  A. DHCP options
  B. NIC teaming
  C. Zone transfers
  D. Relay agent
  E. VLAN ID
  D. Relay agent

• Question 372:

  An administrator received an alert that a backup job has been unsuccessful in the previous three attempts. The administrator discovers the issue occurred while backing up a user's data on a network share.

  Which of the following actions would be best to allow the job to complete successfully?

  A. Enabling open file backups in the backup job
  B. Moving the user's data off the network share
  C. Excluding the user's data from the backup
  D. Changing the backup job to exclude certain file types
  A. Enabling open file backups in the backup job

  ---

  Explanation

  Enabling open file backups allows the backup software to copy files that are currently open or in use by applications. This ensures that even if a file is actively being modified during the backup process, it will still be included in the backup.

• Question 373:

  A technician wants to limit disk usage on a server. Which of the following should the technician implement?

  A. Formatting
  B. Compression
  C. Disk quotas
  D. Partitioning
  C. Disk quotas

  ---

  Explanation

  Disk quotas are a way to limit disk usage on a server by setting a maximum amount of space that each user or group can use. Disk quotas can help manage disk space allocation, prevent disk space exhaustion, and enforce fair usage

  policies. Disk quotas can be set at the volume level or at the folder level, depending on the file system and operating system used.

• Question 374:

  A server shut down after an extended power outage. When power was restored, the system failed to start. A few seconds into booting, the Num Lock, Scroll Lock, and Caps Lock LEDs ashed several times, and the system stopped. Which of the following is the MOST likely cause of the issue?

  A. The keyboard is defective and needs to be replaced.
  B. The system failed before the display card initialized.
  C. The power supply is faulty and is shutting down the system.
  D. The NIC has failed, and the system cannot make a network connection.
  C. The power supply is faulty and is shutting down the system.

  ---

  Explanation

  "A problematic Power Supply Unit is more likely to cause the described behavior. An issue with the PSU could lead to unstable power delivery, which may trigger the server's built-in protection mechanisms, causing it to shut down. Faulty power supply units are known to cause erratic behavior, including unusual light patterns on the indicator LEDs."

• Question 375:

  A syslog server is configured to use UDP port 514. The administrator uses Telnet to check port 514 against the syslog server. However, the syslog server is not responding. Which of the following is the MOST likely reason why the syslog server is not responding?

  A. The syslog server is down.
  B. Telnet does not work on UDP.
  C. The firewall is blocking UDP port 514
  D. The log is full on the syslog server.
  B. Telnet does not work on UDP.

• Question 376:

  A server is only able to connect to a gigabit switch at 100Mb. Other devices are able to access the network port at full gigabit speeds, and when the server is brought to another location, it is able to connect at full gigabit speed. Which of the following should an administrator check first?

  A. The switch management
  B. The VLAN configuration
  C. The network cable
  D. The network drivers
  C. The network cable

  Explanation

• Question 377:

  Which of the following environmental controls must be carefully researched so the control itself does not cause the destruction of the server equipment?

  A. Humidity control system
  B. Sensors
  C. Fire suppression
  D. Heating system
  C. Fire suppression

  ---

  Explanation

• Question 378:

  A server administrator is currently working on an incident. Which of the following steps should the administrator perform before resolving the issue?

  A. Inform the impacted users.
  B. Make the changes to the system.
  C. Determine the probable causes.
  D. Identify changes to the server.
  C. Determine the probable causes.

  ---

  Explanation

  The step that the server administrator should perform before resolving the issue is to determine the probable causes. This step is part of the troubleshooting process that follows a logical and systematic approach to identify and solve

  problems with servers and applications. The troubleshooting process consists of several steps, such as:

  Identify the problem: Gather information from various sources, such as users, logs, or alerts, to understand the symptoms and scope of the problem. Establish a theory of probable cause: Analyze the information and formulate one or more

  possible causes of the problem based on evidence or experience. Test the theory to determine cause: Perform tests or experiments to verify or eliminate each possible cause until the root cause is found. Establish a plan of action to resolve

  the problem and implement the solution:

  Design and execute a plan to fix the problem using appropriate tools and techniques.

  Verify full system functionality and implement preventive measures: Confirm that the problem is resolved and that no other issues arise as a result of the solution. Implement preventive measures to avoid recurrence of the problem or improve

  performance.

  Document findings, actions, and outcomes: Record the details of the problem, its cause, its solution, and its outcome for future reference or knowledge sharing.

• Question 379:

  Which of the following authentication types defines credentials as "something you have"?

  A. Swipe pattern
  B. PIN
  C. Fingerprint
  D. Smart card
  D. Smart card

  ---

  Explanation

  The concept of authentication is rooted in the principle of verifying identity, which is commonly broken down into three categories: "something you know" (like a password or PIN), "something you have" (such as a smart card or a security token), and "something you are" (biometric data, for example, fingerprints). The question asks for the authentication type defined by "something you have."

• Question 380:

  An administrator is troubleshooting a failed NIC in an application server. The server uses DHCP to get all IP configurations, and the server must use a specific IP address. The administrator replaces the NIC, but then the server begins to receive a different and incorrect IP address. Which of the following will enable the server to get the proper IP address?

  A. Modifying the MAC used on the DHCP reservation
  B. Updating the local hosts file with the correct IP address
  C. Modifying the WWNN used on the DHCP reservation
  D. Updating the NIC to use the correct WWNN
  A. Modifying the MAC used on the DHCP reservation

  ---

  Explanation

  A DHCP reservation is a way to assign a specific IP address to a device based on its MAC address, which is a unique identifier for each network interface card (NIC). When the administrator replaced the NIC, the MAC address of the server changed, and the DHCP server no longer recognized it as the same device. Therefore, the DHCP server assigned a different IP address to the server, which was incorrect for the application. To fix this problem, the administrator needs to modify the DHCP reservation to use the new MAC address of the NIC, so that the server can get the proper IP address. A WWNN (World Wide Node Name) is a unique identifier for a Fibre Channel node, which is a device that can communicate over a Fibre Channel network. A WWNN is not related to DHCP or IP addresses, and it is not used for DHCP reservations. Therefore, options B and D are incorrect. Updating the local hosts file with the correct IP address (option C) is also incorrect, because it does not solve the problem of getting the correct IP address from the DHCP server. The hosts file is a local file that maps hostnames to IP addresses, and it is used to override DNS queries. However, it does not affect how the DHCP server assigns IP addresses to devices. Moreover, updating the hosts file manually on every device that needs to communicate with the server is not a scalable or efficient solution.
