NEW QUESTION # 33
In the Juniper Apstra design phase, which object dictates port count, port speed, and how the ports would be used?

• A. network devices
• B. interface map
• C. logical devices
• D. rack type

Answer: B

Explanation:
Interface maps are objects that map interfaces between logical devices and physical hardware devices in the Juniper Apstra design phase. They dictate port count, port speed, and how the ports would be used for achieving the intended network configuration rendering. Interface maps also allow you to select device ports, transformations, and interfaces, provision breakout ports, and disable unused ports.

NEW QUESTION # 34
You connect two single-homed servers using Juniper Apstra as shown in the exhibit. You are using the ERB design blueprint with two virtual networks in a common routing zone. In this scenario, which two types of VXLAN tunnels will be automatically created by the EVPN control plane? (Choose two.)

• A. EVPN signaled route Type-3 VXLAN tunnels
• B. EVPN signaled route Type-2 VXLAN tunnels
• C. EVPN signaled route Type-8 VXLAN tunnels
• D. EVPN signaled route Type-6 VXLAN tunnels

Answer: A,B

Explanation:
EVPN route Type-3 is used to advertise the IP address of the VTEP and the VNIs that it supports.
This allows the VTEPs to discover each other and form VXLAN tunnels for the VNIs that they have in common. EVPN route Type-2 is used to advertise the MAC and IP addresses of the hosts connected to the VTEPs. This allows the VTEPs to learn the MAC-to-IP bindings and the MAC-to- VTEP mappings for the hosts in the same VNI. Therefore, these two types of VXLAN tunnels will be automatically created by the EVPN control plane when using Juniper Apstra with the ERB design blueprint and two virtual networks in a common routing zone.

NEW QUESTION # 35
You want to keep virtual networks isolated from each other within the Juniper Apstra system. In this scenario, what are three ways to accomplish this task? (Choose three.)

• A. Disable Route Target exports when creating the Routing Zones.
• B. Use Connectivity Templates to block access within the same Routing Zone.
• C. Disable IPv4 connectivity when creating the virtual network within the same Routing Zone.
• D. Put each network in different Routing Zones.
• E. Enable Security Policy for virtual networks in the same Routing Zone.

Answer: B,D,E

Explanation:
To keep virtual networks isolated from each other within the Juniper Apstra system, you can use one or more of the following methods:
Enable Security Policy for virtual networks in the same Routing Zone. This allows you to define rules that control the traffic flow between different virtual networks within the same routing zone.
You can specify the source and destination virtual networks, the protocol, the port, and the action (allow or deny) for each rule. The security policy is applied on the ingress interface of the leaf devices.
Use Connectivity Templates to block access within the same Routing Zone. This allows you to customize the connectivity between different racks within the same routing zone. You can create templates that define the link type, the routing protocol, and the access control list (ACL) for each rack pair. The ACL can be used to filter the traffic based on the source and destination IP addresses, the protocol, and the port.
Put each network in different Routing Zones. This allows you to create logical boundaries between different virtual networks based on the route target (RT) values. A routing zone is a collection of virtual networks that share the same RT for importing and exporting routes. Virtual networks in different routing zones do not exchange routes with each other, unless you configure remote EVPN gateways to connect them.

NEW QUESTION # 36
Which two actions are required during Juniper Apstra's deploy phase? (Choose two.)

• A. Assign interlace maps to the blueprint.
• B. Assign user roles to the blueprint.
• C. Assign resources to the blueprint.
• D. Assign device profiles to the blueprint.

Answer: C,D

Explanation:
The deploy phase is the final step in the Juniper Apstra data center fabric design and deployment process. In this phase, you apply the Apstra-rendered configuration to the devices and verify the intent of the blueprint. Based on the web search results, we can infer the following actions are required during the deploy phase:
Assign device profiles to the blueprint. This action associates a specific vendor model to each logical device in the blueprint. Device profiles contain extensive hardware model details, such as form factor, ASIC, CPU, RAM, ECMP limit, and supported features. Device profiles also define how configuration is generated, how telemetry commands are rendered, and how configuration is deployed on a device. Device profiles enable the Apstra system to render and deploy the configuration according to the Apstra Reference Design. Assign resources to the blueprint. This action allocates the physical devices, IP addresses, VLANs, and ASNs to the logical devices, networks, and routing zones in the blueprint. Resources can be assigned manually or automatically by the Apstra system. Assigning resources ensures that the blueprint has all the necessary elements to generate the configuration and deploy the fabric5 . Assign user roles to the blueprint. This action is not required during the deploy phase. User roles are defined at the system level, not at the blueprint level. User roles determine the permissions and access levels of different users in the Apstra system. User roles can be system-defined or custom-defined .
Assign interface maps to the blueprint. This action is not required during the deploy phase.
Interface maps are defined at the design phase, not at the deploy phase. Interface maps are objects that map the logical interfaces of a logical device to the physical interfaces of a device profile. Interface maps enable the Apstra system to generate the correct interface configuration for each device in the fabric.

NEW QUESTION # 37
Referring to the exhibit, how many rack types are used in the staged blueprint?

• A. three
• B. two
• C. six
• D. seven

Answer: B

Explanation:
Referring to the exhibit, the image shows the Racks table under the Staged menu in the Juniper Apstra UI. The Racks table displays the details of the racks that are used in the blueprint, such as the name, rack type, and date. The rack type is a resource that defines the type and number of leaf devices, access switches, and/or generic systems that are used in rack builds. The image shows seven racks in the table, but only two rack types: BorderLeaf and ServerRack.

NEW QUESTION # 38
Which attribute enables Juniper Apstra to scale and manage thousands of devices with a single server instance?

• A. Apstra is based on NGINX.
• B. Apstra is installed as a cloud resource.
• C. Apstra is available as an OVA.
• D. Apstra is a distributed state system.

Answer: D

Explanation:
The attribute that enables Juniper Apstra to scale and manage thousands of devices with a single server instance is that Apstra is a distributed state system. This means that Apstra uses a graph database to store the network topology and configuration data in a distributed and replicated manner across multiple server nodes. This allows Apstra to handle large-scale networks with high performance, reliability, and availability. Apstra also uses a stateful orchestration engine that ensures the network state is always consistent with the intent of the blueprint, which is the logical representation of the network design and behavior. Apstra can automatically detect and resolve any discrepancies between the desired and actual network state, as well as handle any changes or failures in the network.

NEW QUESTION # 39
Referring to the exhibit, what needs to change in the IP fabric to make it a valid IP fabric?

• A. The connection between the two spine nodes must be increased to 40 Gbps.
• B. The IP fabric connections must be increased to a speed greater than 10 Gbps.
• C. The connection between the two spine nodes must be removed.
• D. The IP fabric must consist of only one device model throughout the fabric.

Answer: C

Explanation:
To make the IP fabric a valid IP fabric, the connection between the two spine nodes must be removed. This is because an IP fabric is a network topology that uses a spine-leaf architecture, where the spine devices are only connected to the leaf devices, and the leaf devices are only connected to the spine devices. This creates a non-blocking, high-performance, and scalable network that supports Layer 3 routing protocols such as BGP or OSPF. The connection between the two spine nodes in the exhibit violates the spine-leaf design principle and introduces unnecessary complexity and potential loops in the network.

NEW QUESTION # 40
Which two protocols can be used to advertise EVPN routes? (Choose two.)

• A. OSPF
• B. MP-IBGP
• C. MP-EBGP
• D. IS-IS

Answer: B,C

NEW QUESTION # 41
Which two statements ate correct about the graph query output shown in the exhibit? (Choose two.)

• A. The interface has an IP address assigned to it.
• B. The output shows a LAG connection.
• C. The switch in the output is a Juniper device.
• D. The interface has tags assigned to it.

Answer: B,C

Explanation:
The graph query output shown in the exhibit is a JSON representation of an interface node and its properties in the Apstra graph database. Based on the output, we can infer the following statements:
The output shows a LAG connection. This is true because the interface node has a property called lag_mode which is set to lacp_active, indicating that the interface is part of a link aggregation group (LAG) that uses the Link Aggregation Control Protocol (LACP) to negotiate the link state and parameters.
The switch in the output is a Juniper device. This is true because the interface node has a property called if_name which is set to ae, indicating that the interface name follows the Juniper naming convention for aggregated Ethernet interfaces.
The interface has an IP address assigned to it. This is false because the interface node has properties called ipv4_addr and ipv6_addr which are both set to null, indicating that the interface does not have any IPv4 or IPv6 address configured.
The interface has tags assigned to it. This is false because the interface node has a property called tags which is set to null, indicating that the interface does not have any tags associated with it.

NEW QUESTION # 42
You have designed your fabric in Juniper Apstra prior to deploying the network devices. Which Apstra element in the Staged tab would be used to assist the team that is installing and cabling the devices?

• A. Links table
• B. Connectivity Templates
• C. Managed Devices list
• D. Virtual Networks table

Answer: A

Explanation:
The Links table in the Staged tab shows the physical connections between the devices in the fabric. It provides information such as the source and destination device names, hostnames, serial numbers, roles, interfaces, and link status. The Links table can be used to assist the team that is installing and cabling the devices by verifying that the devices are connected correctly and that the links are operational. The Links table can also be used to troubleshoot any connectivity issues that may arise during the installation process.

NEW QUESTION # 43
Referring to the exhibit, which role does Device A serve in an IP fabric?

• A. spine
• B. super spine
• C. leaf
• D. server

Answer: A

Explanation:
Device A serves as a spine in an IP fabric. An IP fabric is a network architecture that uses a spine-leaf topology to provide high performance, scalability, and reliability for data center networks. A spine- leaf topology consists of two layers of devices: spine devices and leaf devices.
Spine devices are the core devices that interconnect all the leaf devices using equal-cost multipath (ECMP) routing. Leaf devices are the edge devices that connect to the servers, storage, or other network devices. In the exhibit, Device A is connected to four leaf devices using multiple links, which indicates that it is a spine device.

NEW QUESTION # 44
In Juniper Apstra, which statement is correct?

• A. VMware anomaly detection requires an Apstra server running on VMware.
• B. VMware anomaly detection requires a vCenter server configured under External Systems
• C. VMware anomaly detection is on by default.
• D. VMware anomaly detection requires a VMware hypervisor with exports enabled.

Answer: B

Explanation:
VMware anomaly detection is a feature of Apstra that provides visibility and validation of the virtual network settings and the physical network settings in a VMware vSphere environment. To enable this feature, Apstra requires a connection to a vCenter server that manages the ESX/ESXi hosts and the VMs connected to the Apstra-managed leaf switches. The vCenter server must be configured under External Systems in the Apstra web interface, and the vCenter integration must be staged and committed in the blueprint. This allows Apstra to collect information about VMs, ESX/ESXi hosts, port groups, and VDS, and to flag any inconsistencies or mismatches that might affect VM connectivity.

NEW QUESTION # 45
When working with logical devices, you specify where each port group is connected. In this scenario, which two Juniper Apstra Ul options are available to the operator? {Choose two.)

• A. firewall
• B. router
• C. unused
• D. generic

Answer: C,D

Explanation:
When working with logical devices, you specify where each port group is connected by selecting the port group layout and the port speed and role (s) for each port group. The Juniper Apstra UI offers two options to the operator for the port group role: unused and generic.
Unused: This option means that the port group is not configured or used by Apstra. This can be useful for ports that are faulty, reserved, or not part of the data center fabric.
Generic: This option means that the port group is configured with a generic role that is not specific to any device type or function. This can be useful for ports that are used for testing, troubleshooting, or custom purposes.

NEW QUESTION # 46
Which two statements are correct about Time Voyager? {Choose two.)

• A. Time Voyager retains the last ten blueprint commits.
• B. Time Voyager retains up to twenty-five saved revisions.
• C. Time Voyager retains the five most recent blueprint commits.
• D. Time Voyager retains all of the blueprint revisions from the last Juniper Apstra backup.

Answer: B,C

Explanation:
Time Voyager is a feature of Juniper Apstra that allows you to restore previous revisions of a blueprint, which is a logical representation of your network design and configuration. Time Voyager automatically saves the five most recent blueprint commits, which are the changes that you apply to the network. You can also manually save up to twenty-five revisions by keeping them, which prevents them from being overwritten by new commits.

NEW QUESTION # 47
In Juniper Apstra. which three modes are available for devices? (Choose three.)

• A. Ready
• B. Drain
• C. Active
• D. Deploy
• E. Stopped

Answer: A,B,D

Explanation:
Juniper Apstra supports three deploy modes for devices: Deploy, Drain, and Ready. These modes determine the configuration and state of the devices in the data center fabric.
Deploy: This mode applies the full Apstra-rendered configuration to the device, according to the Apstra Reference Design. The device state becomes IS-ACTIVE and the device is ready to carry traffic in the fabric.
Drain: This mode adds a "drain" configuration to the device, which prevents any new traffic from entering the device. The device state becomes IS-READY and the device is prepared for maintenance or decommissioning.
Ready: This mode removes the Apstra-rendered configuration from the device, leaving only the basic configuration such as device hostname, interface descriptions, and port speed/breakout.
The device state becomes IS-READY and the device is not part of the fabric.

NEW QUESTION # 48
You have recently committed a change after creating a new blueprint in Juniper Apstra. In the main dashboard, you see a number of anomalies related to BGR What is a likely cause of these anomalies?

• A. The fabric has not converged yet.
• B. You have misconfigured ASNs.
• C. A generic system has not been configured.
• D. Spine-leaf links are incorrectly set.

Answer: A

Explanation:
In Juniper Apstra, a blueprint is a logical representation of the network design and configuration.
When you create a new blueprint, you need to commit the changes to apply them to the network devices. However, committing the changes does not mean that the network is immediately updated and operational. It may take some time for the network to converge and reflect the new state of the blueprint. During this time, you may see some anomalies related to BGP in the main dashboard, which indicate that the BGP sessions are not established or stable between the devices. These anomalies are usually temporary and will disappear once the network converges and the BGP sessions are up and running.

NEW QUESTION # 49
Multilenancy for applications is achieved by creating virtual networks (VNs) within which construct?

• A. routing table
• B. security policy
• C. connectivity template
• D. routing zone

Answer: D

Explanation:
A routing zone is an L3 domain, the unit of tenancy in multi-tenant networks. You create routing zones for tenants to isolate their IP traffic from one another, thus enabling tenants to re-use IP subnets. In addition to being in its own VRF, each routing zone can be assigned its own DHCP relay server and external system connections. You can create one or more virtual networks within a routing zone, which means a tenant can stretch its L2 applications across multiple racks within its routing zone.

NEW QUESTION # 50
Referring to the exhibit, which statement is correct?

• A. The gray-solid primitives indicate further configuration is requited.
• B. The red-striped primitives indicate that they are incompatible with the connectivity template design.
• C. The gray-solid primitives indicate that they ate incompatible with the connectivity template design.
• D. The red-striped primitives indicate that further configuration is required.

Answer: D

Explanation:
A connectivity template is a set of configuration parameters that can be applied to a device or a group of devices in a blueprint. A blueprint is a logical representation of the network design and intent. A primitive is a basic unit of configuration that can be added to a connectivity template. A primitive can be a link, a peering, a policy, or a service. In the exhibit, the red-striped primitives indicate that further configuration is required for them to be compatible with the connectivity template design. The red stripes mean that the primitive is incomplete or invalid, and it needs to be edited or deleted. For example, the IP Link primitive needs to have the interface name and IP address specified for each end of the link.

NEW QUESTION # 51
What is the purpose of a Juniper Apstra rack?

• A. It stores information on how leaf nodes connect to generic devices
• B. It stores IP address and ASN pool information.
• C. It stores device port data rates and vendor information.
• D. It stores information on how pods connect to super spines.

Answer: A

Explanation:
A Juniper Apstra rack is a physical entity that contains one or more network devices, such as leaf nodes, access switches, or generic systems. A rack is used to organize and manage the network devices in the Apstra software application. A rack has the following characteristics:
It stores information on how leaf nodes connect to generic devices. This is because a rack can include generic systems, which are devices that are not managed by Juniper Apstra, but are connected to the network. A generic system can be a server, a firewall, a load balancer, or any other device that has a network interface. A rack stores the information on how the leaf nodes, which are the devices that provide access to the end hosts, connect to the generic devices, such as the port number, the link speed, the LAG mode, and the roles.
It has a rack type, which defines the type and number of leaf devices, access switches, and/or generic systems that are used in the rack. A rack type is a resource that is created in the data center design phase, and it does not specify the vendor or the model of the devices. A rack type can be predefined or custom-made, and it can be used to create multiple racks with the same structure and configuration.
It has a rack build, which assigns the specific vendor and model of the devices to the rack. A rack build is created in the staged phase, and it uses the rack type as a template. A rack build can also assign the resources, such as the IP addresses, the ASNs, and the VNIs, to the devices in the rack. It has a rack deployment, which applies the network configuration and services to the devices in the rack. A rack deployment is performed in the active phase, and it uses the rack build as a reference. A rack deployment can also monitor the network performance and compliance of the devices in the rack.

NEW QUESTION # 52
In the Juniper Apstra Ul, which three resources are assigned under the Resources menu?
(Choose three.)

• A. logical device pools
• B. ASN pools
• C. IP address pools
• D. VTEP pools
• E. VNI pools

Answer: B,C,E

Explanation:
In the Juniper Apstra UI, the Resources menu allows you to create and manage global and local resources that are used for various elements of the network design and configuration. The Resources menu includes the following three types of resources that can be assigned to the network devices and virtual networks:
ASN pools: These are pools of autonomous system numbers (ASNs) that are used for the underlay routing protocol (EBGP) between the leaf and spine devices. You can create ASN pools with either 2-byte or 4-byte ASNs, and assign them to the logical devices in the blueprint. VNI pools: These are pools of virtual network identifiers (VNIs) that are used for the overlay network (VXLAN) between the end hosts. You can create VNI pools with a range of VNIs, and assign them to the virtual networks in the blueprint.
IP address pools: These are pools of IPv4 or IPv6 addresses that are used for various purposes in the network, such as the loopback addresses for the devices, the IP prefixes for the virtual networks, the host IP addresses for the end hosts, and the gateway IP addresses for the IRB interfaces. You can create IP address pools with a range of IP addresses, and assign them to the logical devices and virtual networks in the blueprint.
The following two types of resources are not assigned under the Resources menu:
VTEP pools: These are not resources that can be created or assigned by the user. VTEPs are VXLAN tunnel endpoints that are automatically generated by the Apstra server based on the loopback IP addresses of the devices. VTEPs are used as the source and destination IP addresses for the VXLAN tunnels in the overlay network.
Logical device pools: These are not resources that can be created or assigned by the user.
Logical device pools are groups of logical devices that share the same role, interface map, and resource assignments in the blueprint. Logical device pools are used to simplify the network design and configuration by applying the same settings to multiple devices.
