CompTIA Server+ Practice Questions

Master the Server Administration Domain

Test your knowledge in the Server Administration domain with these 10 practice questions. Each question is designed to help you prepare for the CompTIA Server+ certification exam with detailed explanations to reinforce your learning.

Question 1

A server administrator is tasked with monitoring server performance. Which of the following metrics is most important for identifying potential memory bottlenecks?

A) Disk read/write speed

B) Network latency

C) CPU utilization

D) Memory usage

Show Answer & Explanation

Correct Answer: D

Explanation: Memory usage is the most important metric for identifying potential memory bottlenecks. High memory usage can indicate that the server is running out of available RAM, which can lead to performance issues.

Question 2

What is the primary benefit of implementing VLANs in a server environment?

A) Increased physical security

B) Improved network performance

C) Simplified cabling

D) Enhanced data encryption

Show Answer & Explanation

Correct Answer: B

Explanation: VLANs improve network performance by segmenting network traffic, reducing broadcast domains, and allowing for better management of network resources. While VLANs can indirectly contribute to security, their primary benefit is network performance.

Question 3

Which of the following best describes the purpose of server clustering in a high availability environment?

A) To consolidate multiple servers into a single physical unit

B) To distribute workloads across multiple servers for load balancing

C) To ensure continued operation by providing failover capabilities

D) To increase the performance of a single application

Show Answer & Explanation

Correct Answer: C

Explanation: Server clustering is used to provide failover capabilities, ensuring continued operation if one server fails. Option A describes server consolidation. Option B is related to load balancing, and Option D is not the primary purpose of clustering.

Question 4

What is the primary purpose of VLANs in a server environment?

A) To increase the physical space in a data center

B) To logically segment network traffic for better management

C) To increase the bandwidth of the server network

D) To physically separate network devices

Show Answer & Explanation

Correct Answer: B

Explanation: VLANs (Virtual Local Area Networks) are used to logically segment network traffic, improving management and security by isolating different types of traffic. They do not increase physical space, bandwidth, or physically separate devices.

Question 5

A server administrator is tasked with setting up a new server role to host web applications. Which server role should they install?

A) File Server

B) Print Server

C) Web Server

D) Database Server

Show Answer & Explanation

Correct Answer: C

Explanation: To host web applications, the administrator should install the Web Server role, which provides the necessary services and infrastructure for hosting websites and web applications. Option A is for file sharing, Option B is for managing print jobs, and Option D is for database management.

Question 6

During a routine check, you notice that a server's CPU utilization is consistently above 90%. What is the best initial action to take?

A) Immediately restart the server

B) Install additional CPUs

C) Investigate the processes consuming high CPU resources

D) Upgrade the server's RAM

Show Answer & Explanation

Correct Answer: C

Explanation: When CPU utilization is consistently high, the best initial action is to investigate the processes consuming the most CPU resources. This helps identify if there are unnecessary processes or if an application needs optimization.

Question 7

A company is planning to deploy a new web application. Which server role should be configured to host the application?

A) File server

B) Print server

C) Web server

D) Database server

Show Answer & Explanation

Correct Answer: C

Explanation: A web server role should be configured to host a web application, as it is designed to handle HTTP requests and serve web content. File servers manage file storage, print servers manage print jobs, and database servers handle database operations.

Question 8

What is the primary purpose of implementing VLANs in a server environment?

A) To increase the physical security of the network

B) To reduce the number of physical switches required

C) To logically segment network traffic for improved management and security

D) To increase the speed of the network

Show Answer & Explanation

Correct Answer: C

Explanation: VLANs (Virtual Local Area Networks) are used to logically segment network traffic, which helps in improving network management and security. They do not inherently increase speed or physical security, nor do they necessarily reduce the number of physical switches needed.

Question 9

A server administrator notices that a server is running slowly. Which of the following performance metrics should be checked first?

A) Disk Usage

B) Network Latency

C) CPU Utilization

D) Power Supply Voltage

Show Answer & Explanation

Correct Answer: C

Explanation: CPU Utilization is a primary metric to check when a server is running slowly, as high CPU usage can severely impact performance. Disk usage, network latency, and power supply voltage are also important but may not be the immediate cause of slowness.

Question 10

A company is planning to migrate data from an old server to a new one. Which of the following should be considered first to ensure a smooth migration?

A) The physical location of the new server

B) The network bandwidth available during migration

C) The compatibility of data formats between servers

D) The power requirements of the new server

Show Answer & Explanation

Correct Answer: C

Explanation: Ensuring compatibility of data formats between the old and new servers is crucial to prevent data corruption or loss during migration. Options A, B, and D are important but secondary to data compatibility.
