CompTIA Cloud+ Practice Questions

Master the Security Domain

Test your knowledge in the Security domain with these 5 practice questions. Each question is designed to help you prepare for the CompTIA Cloud+ certification exam with detailed explanations to reinforce your learning.

Question 1

What is the primary advantage of using a cloud-based Web Application Firewall (WAF) over a traditional on-premises firewall?

A) Higher throughput capacity

B) Lower latency

C) Automatic scaling and updates

D) Reduced bandwidth usage

Show Answer & Explanation

Correct Answer: C

Explanation: Cloud-based WAFs offer automatic scaling to handle varying traffic loads and receive regular updates from the provider to protect against the latest threats, making them more flexible and easier to manage than on-premises solutions.

Question 2

A company is implementing a cloud-based intrusion detection system (IDS). What is one of the main challenges they might face with this implementation?

A) Lack of scalability to handle increased traffic.

B) Difficulty in integrating with existing on-premises security tools.

C) Inability to monitor encrypted traffic.

D) High latency in detecting and responding to threats.

Show Answer & Explanation

Correct Answer: C

Explanation: One of the main challenges with cloud-based IDS is the inability to monitor encrypted traffic without decrypting it first, which can introduce privacy concerns and technical challenges. Option A is less likely as cloud solutions are typically scalable. Option B can be addressed with proper integration tools. Option D is not a common issue with modern cloud-based IDS solutions, which are designed to provide real-time threat detection.

Question 3

A company is subject to GDPR regulations and must ensure data privacy in its cloud operations. Which of the following should be prioritized to comply with GDPR?

A) Encrypting all data in transit between cloud services.

B) Implementing a data loss prevention (DLP) solution.

C) Ensuring data processing agreements are in place with the cloud provider.

D) Regularly backing up data to multiple geographic locations.

Show Answer & Explanation

Correct Answer: C

Explanation: GDPR compliance requires organizations to have data processing agreements in place with any third parties that process personal data on their behalf, including cloud providers. This ensures that data handling practices meet GDPR standards. While encrypting data (Option A) and implementing DLP (Option B) are important security measures, they are not specific to GDPR compliance. Regular backups (Option D) are good practice but not directly related to GDPR requirements.

Question 4

An organization is migrating its sensitive data to a cloud environment and needs to ensure that the data is encrypted both at rest and in transit. Which of the following combinations of services and practices would best achieve this goal?

A) Use a cloud provider's built-in encryption service for data at rest and implement TLS for data in transit.

B) Implement a third-party encryption tool for data at rest and use a VPN for data in transit.

C) Rely on the cloud provider's network security features for data in transit and use client-side encryption for data at rest.

D) Use a cloud provider's firewall for data in transit and enable server-side encryption for data at rest.

Show Answer & Explanation

Correct Answer: A

Explanation: Option A is correct because using a cloud provider's built-in encryption service ensures that data at rest is encrypted using industry-standard protocols, and implementing TLS (Transport Layer Security) is a widely recognized best practice for encrypting data in transit. Option B is incorrect because while a third-party tool can be effective, it adds complexity and potential compatibility issues. VPNs are not primarily used for encrypting data in transit in the same way TLS is. Option C is incorrect because relying solely on network security features without encryption like TLS can leave data vulnerable during transmission. Option D is incorrect because firewalls do not encrypt data; they control access. Server-side encryption is correct for data at rest, but it should be combined with TLS for data in transit.

Question 5

In the context of cloud security, what is the primary purpose of a Web Application Firewall (WAF)?

A) To encrypt data in transit between cloud services.

B) To monitor and log API requests for auditing purposes.

C) To protect web applications by filtering and monitoring HTTP traffic.

D) To manage user identities and enforce access controls.

Show Answer & Explanation

Correct Answer: C

Explanation: A Web Application Firewall (WAF) is designed to protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet. It helps in preventing attacks such as cross-site scripting (XSS), SQL injection, and other web application vulnerabilities. Options A, B, and D describe different security functions not directly related to a WAF.
