NEW QUESTION # 198
A systems administrator is setting up a new server that will be used as a DHCP server. The administrator installs the OS but is then unable to log on using Active Directory credentials. The administrator logs on using the local administrator account and verifies the server has the correct IP address, subnet mask, and default gateway. The administrator then gets on another server and can ping the new server. Which of the following is causing the issue?
- A. Port 443 is not open on the firewall
- B. The local hosts file is blank
- C. The server is not joined to the domain
- D. The server is experiencing a downstream failure
Answer: C
Explanation:
The server is not joined to the domain is causing the issue. A domain is a logical grouping of computers that share a common directory database and security policy on a network. Active Directory is a Microsoft technology that provides domain services for Windows-based computers. To use Active Directory credentials to log on to a server, the server must be joined to the domain that hosts Active Directory. If the server is not joined to the domain, it will not be able to authenticate with Active Directory and will only accept local accounts for logon. To join a server to a domain, the administrator must have a valid domain account with sufficient privileges and must know the name of the domain controller that hosts Active Directory.
NEW QUESTION # 199
An administrator is configuring a new server for use as a database server. It will have two mirrored drives to hold the operating system, and there will be three drive bays remaining for storage Which of the following RAID levels will yield the BEST combination of available space and redundancy?
- A. RAID
- B. RAIDS
- C. RAID 1
- D. RAID 10
Answer: D
Explanation:
RAID 10 is the RAID level that will yield the best combination of available space and redundancy when configuring a new server for use as a database server with two mirrored drives for the operating system and three drive bays remaining for storage. RAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data. It requires a minimum of four disks and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved. RAID 10 provides high performance, fault tolerance, and fast recovery, but it reduces storage capacity by half. RAID 0 is a RAID configuration that splits data across two or more drives without parity or redundancy. It improves performance but offers no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 1 is a RAID configuration that duplicates data across two or more drives. It provides fault tolerance and improves read performance, but reduces storage capacity by half. If one drive fails in RAID 1, the other drive can continue to operate without data loss or system downtime. RAID 5 is a RAID configuration that stripes data across three or more drives with parity information. It provides fault tolerance and improves performance, but reduces storage capacity by one drive's worth of space. RAID 5 can tolerate one drive failure without data loss, but not two or more.

NEW QUESTION # 200
A server technician is installing a new server OS on legacy server hardware. Which of the following should the technician do FIRST to ensure the OS will work as intended?
- A. Migrate the physical server to a virtual server.
- B. Consult the HCL to ensure everything is supported.
- C. Low-level format the hard drives to ensure there is no old data remaining.
- D. Make sure the case and the fans are free from dust to ensure proper cooling.
Answer: B
Explanation:
Explanation
The first thing that the technician should do before installing a new server OS on legacy server hardware is to consult the HCL (Hardware Compatibility List) to ensure everything is supported. The HCL is a list of hardware devices and components that are tested and certified to work with a specific OS or software product.
The HCL helps to avoid compatibility issues and performance problems that may arise from using unsupported or incompatible hardware. Migrating the physical server to a virtual server may be a good option to improve scalability and flexibility, but it requires additional hardware and software resources and may not be feasible for legacy server hardware. Low-level formatting the hard drives may be a good practice to erase any old data and prepare the drives for a new OS installation, but it does not guarantee that the hardware will work with the new OS. Making sure the case and the fans are free from dust may be a good practice to ensure proper cooling and prevent overheating, but it does not guarantee that the hardware will work with the new OS.

Which of the following would be BEST to help protect an organization against social engineering?
- A. Single sign-on
- B. More complex passwords
- C. An updated code of conduct to enforce social media
- D. Recurring training and support
Answer: D
Explanation:
The best way to protect an organization against social engineering is to provide recurring training and support.
Social engineering is a type of attack that exploits human psychology and behavior to manipulate people into divulging confidential information or performing malicious actions. Social engineering can take various forms, such as phishing emails, phone calls, impersonation, baiting, or quid pro quo. The best defense against social engineering is to educate and empower the employees to recognize and avoid common social engineering techniques and report any suspicious activities or incidents. Recurring training and support can help raise awareness and reinforce best practices among the employees.
NEW QUESTION # 202
An administrator is deploying a new secure web server. The only administration method that is permitted is to connect via RDP. Which of the following ports should be allowed? (Select TWO).
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
- F. 5
- G. 6
Answer: C,E
Explanation:
Explanation
Port 443 is the default port for HTTPS, which is the protocol used for secure web communication. HTTPS uses SSL/TLS certificates to encrypt the data between the web server and the browser. Port 443 is commonly used for web servers that need to provide secure services, such as online banking, e-commerce, or email. By allowing port 443, the administrator can access the web server's interface and manage its settings1.
Port 3389 is the default port for RDP, which is the protocol used for remote desktop connection. RDP allows a user to remotely access and control another computer over a network. Port 3389 is commonly used for remote administration, technical support, or remote work. By allowing port 3389, the administrator can connect to the web server's desktop and perform tasks that require graphical user interface2.
NEW QUESTION # 203
Users report that the FinanceApp software is not running, and they need immediate access. Issues with the FinanceApp software occur every week after the IT team completes server system updates. The users, however, do not want to contact the help desk every time the issue occurs. The users also report the new MarketApp software is not usable when it crashes, which can cause significant downtime. The technician who restarted the MarketApp software noticed it is running under a test account, which is a likely cause of the crashes.
INSTRUCTIONS
Using the Services menu provided, modify the appropriate application services to remedy the stated issues.
Answer:
Explanation:
See the solution in explanation.
Explanation:
FinanceApp software is running as a service named "FinanceApp Service". The service description says
"Provides financial data and calculations for the FinanceApp software". The service status is "Stopped", which means that the service is not running and the software is not functional. The service startup type is "Manual", which means that the service needs to be started manually by the user or the administrator. The service log on as is "Local System", which means that the service runs under a predefined local account that has extensive privileges on the local computer.
To fix the issue with the FinanceApp software, you need to do two things:
* First, you need to start the service, so that the software can run. To do this, you can right-click on the service name and select "Start" from the menu. Alternatively, you can select the service name and click on the "Start" button on the toolbar. You should see a message saying that the service has started successfully.
* Second, you need to change the service startup type, so that the service can start automatically every time the server boots up. This way, you don't have to contact the help desk every time the issue occurs.
To do this, you can right-click on the service name and select "Properties" from the menu. Alternatively, you can select the service name and click on the "Properties" button on the toolbar. You should see a window with several tabs and options. On the "General" tab, under "Startup type", you can select
"Automatic" from the drop-down list. Then, click on "OK" to save your changes.
By doing these two steps, you should be able to use the FinanceApp software without any problems.
The MarketApp software is running as a service named "MarketApp Service". The service description says
"Provides market data and analysis for the MarketApp software". The service status is "Running", which means that the service is running and the software is functional. However, as you reported, the software may crash sometimes, which can cause significant downtime. The service startup type is "Automatic", which means that the service starts automatically every time the server boots up. The service log on as is
"TestAccount", which is a test account that was probably used for development or testing purposes.
To fix the issue with the MarketApp software, you need to do one thing:
* You need to change the service log on as, so that the service runs under a proper account that has sufficient permissions and security settings for production use. To do this, you can right-click on the service name and select "Properties" from the menu. Alternatively, you can select the service name and click on the "Properties" button on the toolbar. You should see a window with several tabs and options.
On the "Log On" tab, under "Log on as", you can select either "Local System account" or "This account". If you choose "Local System account", then the service will run under a predefined local account that has extensive privileges on the local computer. If you choose "This account", then you will need to enter a valid username and password for an account that has appropriate permissions and security settings for running the service. You may need to consult with your IT team or your software vendor to determine which option is best for your situation. Then, click on "OK" to save your changes.
NEW QUESTION # 204
A server administrator is trying to determine the cause of a slowdown on a database server. Upon investigation, the administrator determines the issue is in the storage subsystem. Which of the following will most likely resolve this issue?
- A. Extending capacity by installing a 4TB SATA disk
- B. Implementing deduplication on the storage
- C. Increasing IOPS by implementing flash storage
- D. Reformatting the disk as FAT32
Answer: C
Explanation:
Explanation
Increasing IOPS (input/output operations per second) by implementing flash storage is the most likely solution to resolve a slowdown issue in the storage subsystem of a database server. Flash storage uses solid-state drives (SSDs) that have faster read/write speeds and lower latency than traditional hard disk drives (HDDs). This can improve the performance of database queries and transactions. Implementing deduplication, extending capacity, or reformatting the disk as FAT32 are not likely to resolve the issue, as they do not affect the IOPS of the storage subsystem.

NEW QUESTION # 205
Winch of the following is a type of replication in which all files are replicated, all the time?
- A. Synthetic full
- B. Application consistent
- C. Full
- D. Constant
Answer: D
Explanation:
Explanation
Constant replication is a type of replication in which all files are replicated, all the time. Replication is a process of copying data from one location to another for backup, recovery, or distribution purposes. Constant replication is also known as real-time replication or synchronous replication. It ensures that any changes made to the source data are immediately reflected on the target data without any delay or lag. Constant replication provides high availability and consistency, but it requires high bandwidth and low latency. Application consistent replication is a type of replication that ensures that the replicated data is consistent with the state of the application that uses it. It involves quiescing or pausing the application before taking a snapshot of the data and resuming the application after the snapshot is taken. Application consistent replication provides better recovery point objectives than crash consistent replication, which does not quiesce the application before taking a snapshot. Synthetic full replication is a type of replication that involves creating a new full backup by using the previous full backup and related incremental backups. It reduces the backup window and network bandwidthconsumption by transferring only changed data from the source to the target. Full replication is a type of replication that involves copying all data from the source to the target regardless of whether it has changed or not. It provides a complete backup of the data, but it requires more storage space and network bandwidth than incremental or differential replication. References:

- A. Thresholds
- B. Event logs
- C. Uptime lengths
- D. Disk quotas
Answer: A
Explanation:
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:
Configuringthresholdsallows the monitoring application to define limits (e.g., CPU usage >90%, disk space <
10%) that trigger email alerts when exceeded. This proactive measure helps administrators address issues before they escalate.
* Event logs:Provide historical data but do not send alerts.
* Disk quotas:Restrict user disk usage but are unrelated to alerts.
* Uptime lengths:Measure server runtime but do not trigger alerts.
NEW QUESTION # 207 
Which of the following actions should the server administrator perform on the server?
- A. Close ports 80 and 443 and rerun the scan.
- B. Close port 3389 and rerun the scan.
- C. Close all ports and rerun the scan.
- D. Close ports 69 and 1010 and rerun the scan.
Answer: B
Explanation:
Explanation
The server administrator should close port 3389 and rerun the scan. Port 3389 is used for Remote Desktop Protocol (RDP), which allows remote access and control of a server. RDP is vulnerable to brute-force attacks, credential theft, and malware infection. Closing port 3389 can prevent unauthorized access and improve the security of the server. The other ports are not as risky as port 3389 and can be left open for legitimate purposes. References: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.4:
Given a scenario, implement proper environmental controls and techniques.
NEW QUESTION # 208
An administrator has been troubleshooting a server issue. The administrator carefully questioned the users and examined the available logs. Using this information, the administrator was able to rule out several possible causes and develop a theory as to what the issue might be. Through further testing, the administrator's theory proved to be correct. Which of the following should be the next step to troubleshoot the issue?
- A. Establish an action plan.
- B. Implement the solution.
- C. Escalate the issue to the management team.
- D. Document the findings and actions.
Answer: A
Explanation:
The next step to troubleshoot the issue after developing and testing a theory is to establish an action plan. This involves identifying the steps needed to implement the solution, estimating the time and resources required, and evaluating the potential risks and impacts of the solution. Documenting the findings and actions, escalating the issue to the management team, or implementing the solution are steps that should be done after establishing an action plan.

- A. rsync
- B. scp
- C. copy
- D. robocopy
Answer: D
Explanation:
Robocopy (Robust File Copy) is a command-line tool that can copy files and folders between Windows servers or computers. It has many features and options that can ensure all the data is copied consistently, such as retrying failed copies, resuming interrupted copies, copying permissions and attributes, mirroring source and destination directories, and logging the copy progress and results.

NEW QUESTION # 210
A server administrator needs to harden a server by only allowing secure traffic and DNS inquiries. A port scan reports the following ports are open:
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
- F. 5
Answer: C
Explanation:
The administrator should only allow secure traffic and DNS inquiries on the server, which means that only ports 22, 53, and 443 should be open. Port 22 is used for SSH (Secure Shell), which is a protocol that allows secure remote login and command execution over a network connection using a command-line interface (CLI).
Port 53 is used for DNS (Domain Name System), which is a service that translates domain names into IP addresses and vice versa. Port 443 is used for HTTPS (Hypertext Transfer Protocol Secure), which is a secure version of HTTP that encrypts the data exchanged between a web browser and a web server.
NEW QUESTION # 211
Which of me following is the BEST action to perform before applying patches to one of the hosts in a high availability cluster?
- A. Failover all VMs.
- B. Fallback cluster services.
- C. Disable the heartbeat network.
- D. Set the cluster to active-active.
Answer: A
Explanation:
This is the best action to perform before applying patches to one of the hosts in a high availability cluster. A high availability cluster is a group of hosts that act like a single system and provide continuous uptime. A high availability cluster is often used for load balancing, backup, and failover purposes. Failover is a process of transferring workloads from one host to another in case of a failure or maintenance. By failing over all VMs (Virtual Machines) from the host that needs to be patched to another host in the cluster, the technician can ensure that there is no downtime or data loss during the patching process. Disabling the heartbeat network is not a good action to perform, as this would disrupt the communication and synchronization between the hosts in the cluster. Fallback cluster services is not a valid term, but it may refer to restoring cluster services after a failover, which is not relevant before applying patches. Setting the cluster to active-active is not a good action to perform, as this would increase the load on both hosts and reduce redundancy.
