Which of the following server types would benefit MOST from the use of a load balancer?
A. DNS server
B. File server
C. DHCP server
D. Web server
Show Answer
Correct Answer: D
Explanation: Web servers commonly receive large volumes of client requests, so a load balancer can distribute traffic across multiple servers to improve performance and availability.
Question 132
Which of the following techniques can be configured on a server for network redundancy?
A. Clustering
B. Virtualizing
C. Cloning
D. Teaming
Show Answer
Correct Answer: D
Explanation: Teaming combines multiple network interfaces on a server so connectivity can continue if one interface or link fails. Clustering provides redundancy at the server or service level, rather than specifically configuring network interfaces.
Question 133
Which of the following backup methods protects all the changes that have occurred since the last full backup?
A. Incremental
B. Archive
C. Differential
D. Snapshot
Show Answer
Correct Answer: C
Explanation: A differential backup captures all changes since the last full backup. An incremental backup captures only changes since the most recent backup.

Question 134
A new virtual server was deployed in a perimeter network. Users have reported the time on the server has been incorrect. The engineer has verified the configuration, and the internal time servers are configured properly. Which of the following should the engineer do to resolve this issue?
A. Check the firewall rules.
B. Replace the CMOS battery in the server.
C. Restart the time servers.
D. Manually correct the time.
Show Answer
Correct Answer: A
Explanation: Check the firewall rules to ensure NTP traffic (typically UDP port 123) is allowed between the virtual server in the perimeter network and the internal time servers. A VM has no CMOS battery, and manually setting the time would only be a temporary fix.
Question 135
A server administrator is installing a new server on a manufacturing floor. Because the server is publicly accessible, security requires the server to undergo hardware hardening. Which of the following actions should the administrator take?
A. Close unneeded ports.
B. Disable unused services.
C. Set a BIOS password.
D. Apply driver updates.
Show Answer
Correct Answer: C
Explanation: Set a BIOS password to restrict unauthorized access to firmware settings and boot configuration, which is a hardware-level hardening measure. Closing ports and disabling services are software/network hardening, while driver updates are maintenance.
Question 136
A technician is tasked with upgrading 24 hosts simultaneously with a Type 1 hypervisor. Which of the following protocols should the technician use for this upgrade?
A. VPN
B. TFTP
C. SSH
D. HTTP
Show Answer
Correct Answer: B
Explanation: TFTP is commonly used to distribute boot files and installation images to multiple hosts over a network, such as during PXE-based hypervisor deployments.
Question 137
Users at a company are licensed to use an application that is restricted by the number of active sessions. Which of the following best describes this licensing model?
A. Per-server
B. Per-seat
C. Per-concurrent user
D. Per-core
Show Answer
Correct Answer: C
Explanation: Per-concurrent-user licensing limits how many people can use the application at the same time, typically by counting active sessions rather than named users or installed copies.

Question 138
Following a recent power outage, a server in the data center has been constantly going offline and losing its configuration. Users have been experiencing access issues while using the application on the server. The server technician notices the date and time are incorrect when the server is online. All other servers are working. Which of the following would MOST likely cause this issue? (Choose two.)
A. The server has a faulty power supply.
B. The server has a CMOS battery failure.
C. The server requires OS updates.
D. The server has a malfunctioning LED panel.
E. The servers have NTP configured.
F. CPU frequency scaling is set too high.
Show Answer
Correct Answer: A, B
Explanation: A faulty power supply can cause the server to shut down repeatedly. A failed CMOS battery can cause it to lose firmware settings and the correct date and time after power loss.

Question 139
A technician is troubleshooting a server issue. The technician has determined several possible causes of the issue and has identified various solutions. Which of the following should the technician do NEXT?
A. Consult internet forums to determine which is the most common cause and deploy only that solution.
B. Test each solution individually to determine the root cause, rolling back the changes in between each test.
C. Implement the shortest solution first to identify the issue and minimize downtime.
D. Test each solution in succession and restore the server from the latest snapshot.
Show Answer
Correct Answer: B
Explanation: Test each proposed solution individually and roll back the change before testing the next. This isolates the cause and avoids confounding results; restoring from a snapshot after applying solutions in succession does not identify which one resolved the issue.
Question 140
An administrator is troubleshooting an application performance issue on a virtual server with two vCPUs. The application performance logs indicate CPU contention. The administrator adds more vCPU cores to the VM, yet the issue persists. Which of the following is the MOST likely reason for this issue?
A. The server has high page utilization.
B. The server has high disk latency.
C. The application is single-threaded.
D. The application cannot be virtualized.
Show Answer
Correct Answer: C
Explanation: A single-threaded application can execute its workload on only one CPU core at a time. Adding vCPUs therefore may not improve its performance or resolve the CPU contention.
