CompTIA Server+ Practice Questions

Master the Security and Disaster Recovery Domain

Test your knowledge in the Security and Disaster Recovery 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

What is the primary purpose of a server decommissioning procedure?

A) To upgrade the server hardware for better performance

B) To ensure data is securely erased before disposal

C) To test the server's disaster recovery capabilities

D) To migrate data to a cloud environment

Show Answer & Explanation

Correct Answer: B

Explanation: The primary purpose of a server decommissioning procedure is to securely erase data to prevent unauthorized access and ensure compliance with data protection regulations. Options A and D are not related to decommissioning, and C is related to disaster recovery testing, not decommissioning.

Question 2

A company wants to prevent unauthorized physical access to its server room. Which of the following controls is most effective?

A) Installing an IDS system

B) Implementing biometric access controls

C) Using software firewalls

D) Deploying network segmentation

Show Answer & Explanation

Correct Answer: B

Explanation: Biometric access controls, such as fingerprint or retina scanners, provide a high level of security by ensuring that only authorized personnel can physically access the server room. IDS, software firewalls, and network segmentation do not control physical access.

Question 3

A company has implemented multi-factor authentication (MFA) for its servers. What is the primary benefit of this security measure?

A) It simplifies the login process

B) It increases the complexity of passwords

C) It enhances security by requiring multiple forms of verification

D) It reduces the need for password changes

Show Answer & Explanation

Correct Answer: C

Explanation: MFA enhances security by requiring multiple forms of verification, such as something you know (password) and something you have (token). It does not simplify login, increase password complexity, or reduce the need for password changes.

Question 4

What is the primary benefit of implementing a Security Information and Event Management (SIEM) system in a server environment?

A) It increases server processing speed

B) It centralizes security monitoring and analysis

C) It provides automatic software updates

D) It eliminates the need for a firewall

Show Answer & Explanation

Correct Answer: B

Explanation: A SIEM system centralizes security monitoring and analysis, allowing for better detection and response to security incidents. It does not increase processing speed, provide software updates, or eliminate the need for a firewall.

Question 5

Which of the following is a key benefit of using Multi-Factor Authentication (MFA) in server environments?

A) It simplifies password management

B) It provides a single point of failure

C) It enhances user convenience

D) It provides an additional layer of security

Show Answer & Explanation

Correct Answer: D

Explanation: MFA provides an additional layer of security by requiring more than one form of verification to access systems, making unauthorized access more difficult. It does not simplify password management (A), create a single point of failure (B), or necessarily enhance convenience (C).

Question 6

An organization has implemented a disaster recovery plan that includes off-site data backups. Which of the following is a critical step to ensure the effectiveness of this plan?

A) Regularly test the recovery process

B) Encrypt all data before backup

C) Perform daily network scans

D) Update the recovery plan quarterly

Show Answer & Explanation

Correct Answer: A

Explanation: Regularly testing the recovery process ensures that the disaster recovery plan is effective and that data can be successfully restored from off-site backups. While encryption, network scans, and plan updates are important, they do not directly test the recovery process.

Question 7

In a disaster recovery plan, what is the purpose of conducting regular recovery testing?

A) To ensure the backup tapes are stored securely

B) To verify the effectiveness of the recovery process

C) To reduce the cost of maintaining backup hardware

D) To improve the speed of daily operations

Show Answer & Explanation

Correct Answer: B

Explanation: Regular recovery testing verifies that the disaster recovery process is effective and that systems can be restored to operational status. Secure storage, cost reduction, and operation speed are not directly related to recovery testing.

Question 8

Which of the following is a critical step in server decommissioning procedures to ensure data security?

A) Performing a firmware upgrade

B) Disabling unused services

C) Wiping or physically destroying storage media

D) Implementing a new backup strategy

Show Answer & Explanation

Correct Answer: C

Explanation: Wiping or physically destroying storage media is a critical step in server decommissioning to ensure that no residual data can be recovered and accessed by unauthorized individuals.

Question 9

A server administrator needs to ensure data is secure both at rest and in transit. Which combination of technologies should they implement?

A) Data encryption and VLAN segmentation

B) Data encryption and SSL/TLS

C) RAID 6 and VLAN segmentation

D) RAID 6 and SSL/TLS

Show Answer & Explanation

Correct Answer: B

Explanation: Data encryption secures data at rest, while SSL/TLS secures data in transit by encrypting data being transmitted over networks. RAID 6 is for data redundancy, and VLAN segmentation is for network organization, not encryption.

Question 10

An administrator is tasked with hardening a server. Which of the following actions should they prioritize?

A) Install additional RAM

B) Disable unused services

C) Upgrade the CPU

D) Increase the cooling capacity

Show Answer & Explanation

Correct Answer: B

Explanation: Disabling unused services is a critical step in server hardening as it reduces the attack surface by eliminating potential vulnerabilities. Installing RAM (A), upgrading the CPU (C), and increasing cooling (D) are related to performance and hardware management, not security hardening.
