An administrator is alerted to an issue with server hardware deployed as a virtualization host. The alert indicates a predictive failure in a DIMM module. Which of the following is the BEST action for the administrator to take?
A. Replace the failed module during the next scheduled downtime.
B. Hot swap the failed module immediately.
C. Schedule an outage to replace the failed module immediately.
D. Hot swap the failed module during the next scheduled downtime.
Show Answer
Correct Answer: C
Explanation: A predictive failure warning calls for prompt preventive replacement, but DIMMs generally are not hot-swappable. Schedule a controlled outage and replace the module as soon as possible rather than waiting for routine downtime.
Question 172
An administrator has been asked to increase the storage capacity of a stand-alone file server, but no further expansion slots are available. Which of the following would be the FASTEST solution to implement with no downtime?
A. Configure a RAID array.
B. Replace the current drives with higher-capacity disks.
C. Implement FCoE for more storage capacity.
D. Connect the server to a SAN.
Show Answer
Correct Answer: D
Explanation: Connecting the server to a SAN adds externally provided storage without replacing the existing drives, allowing capacity to be expanded while the server remains online. Replacing drives risks downtime, and RAID or FCoE alone does not directly provide additional storage capacity.
Question 173
An application server cannot communicate with a newly installed database server. The database server, which has static IP information, is reading the following output from ipconfig:
IP: 10.0.10.240
Mask: 255.255.255.128
Gateway: 10.0.10.1
The application server is reading the following output from ipconfig:
IP: 10.0.10.25
Mask: 255.255.255.128
Gateway: 10.0.10.1
Which of the following MOST likely contains an error?
A. IP address
B. DHCP
C. Gateway
D. Subnet mask
Show Answer
Correct Answer: A
Explanation: With a /25 mask, the application server and gateway are on 10.0.10.0/25, while 10.0.10.240 is on 10.0.10.128/25. The database server’s IP address is therefore the most likely misconfiguration for communication on the same subnet.
Question 174
Ann, an administrator, has been troubleshooting a server issue. She carefully questioned the users and examined the available logs. Using this information, she was able to rule out several possible causes and develop a theory as to what the issue might be. Through further testing, her theory proved to be correct. Which of the following should be the NEXT step to troubleshoot the issue?
A. Document the findings and actions.
B. Escalate the issue to the management team.
C. Implement the solution.
D. Establish an action plan
Show Answer
Correct Answer: D
Explanation: After testing confirms the theory of probable cause, the next step is to establish a plan of action to resolve the issue. The solution is implemented only after that plan is established.
Question 175
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 flashed 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.
Show Answer
Correct Answer: B
Explanation: The flashing keyboard LEDs indicate an early POST error. Because the system stops before it can display an error, it most likely failed before the display card initialized. The pattern does not, by itself, indicate a defective keyboard or NIC.
Question 176
Which of the following backup types copies changed data from a server and then combines the backups on the backup target?
A. Differential
B. Incremental
C. Synthetic full
D. Snapshot
Show Answer
Correct Answer: C
Explanation: A synthetic full backup combines an existing full backup with subsequent changed-data backups on the backup target, creating a new full backup without rereading all the source data.
Question 177
The management team at a healthcare organization is concerned about being able to access the daily vital records if there is an IT disaster that causes both servers and the network to be offline. Which of the following backup types can the organization use to mitigate this risk?
A. Tape
B. Cloud
C. Disk
D. Print
Show Answer
Correct Answer: D
Explanation: Printed copies can be accessed without servers, computers, or a network, making them the suitable backup for vital daily records during the described outage.
Question 178
A change in policy requires a complete backup of the accounting server every seven days and a backup of modified data every day. Which of the following would be BEST to restore a full backup as quickly as possible in the event of a complete loss of server data?
A. A full, weekly backup with daily open-file backups
B. A full, weekly backup with daily archive backups
C. A full, weekly backup with daily incremental backups
D. A full, weekly backup with daily differential backups
Show Answer
Correct Answer: D
Explanation: Daily differential backups capture all changes made since the most recent full backup. After a data loss, restore the latest weekly full backup and only the latest differential backup. Incremental backups would require restoring each daily backup in sequence, taking longer.
Question 179
A server administrator is installing servers in a rack that does not have rack unit markings on the sides. The available open space for the new servers is approximately 3.5in (8.9cm) high. Which of the following is the LARGEST server size that can fit in this space?
A. 1U
B. 2U
C. 3U
D. 4U
Show Answer
Correct Answer: B
Explanation: One rack unit (1U) is 1.75 inches (4.45 cm), so a 2U server is nominally 3.5 inches (8.9 cm) high and is the largest listed size that fits the available space.
Question 180
A hardware technician is installing 19 1U servers in a 42-unit rack. The technician needs to allocate enough space per server for optimal air flow.
Which of the following unit sizes should be allocated per server?
A. 1U
B. 2U
C. 3U
D. 4U
Show Answer
Correct Answer: A
Explanation: Each server is 1U, and rack servers are designed to maintain proper airflow when installed in adjacent rack units. Allocate 1U per server; gaps are not required for airflow.
