6 Free CompTIA Security+ SY0-701 Security Architecture Practice Questions with Answers

Sample Question 1 — Security Architecture

Your company is migrating to a cloud-based infrastructure. You need to design a secure architecture that minimizes risk. Which approach best balances security and agility?

  1. A. Deploy all applications and data to a single cloud provider's public cloud.
  2. B. Utilize a multi-cloud strategy with strong identity and access management (IAM) across all platforms. (Correct answer)
  3. C. Keep all sensitive data on-premises and only use the cloud for non-critical applications.
  4. D. Employ a hybrid cloud model with minimal integration between on-premises and cloud environments.

Correct answer: B

Explanation: A multi-cloud strategy offers resilience and avoids vendor lock-in. Strong IAM across platforms is crucial for centralizing security management. Option A is risky due to single point of failure. Option C limits the benefits of cloud computing, and Option D creates security and management complexities. Generated by AI

Sample Question 2 — Security Architecture

A new software application requires access to both a legacy database and a cloud-based storage service. What architectural principle should be prioritized to minimize risk from a security perspective?

  1. A. Least privilege. (Correct answer)
  2. B. Separation of duties.
  3. C. Defense in depth.
  4. D. Data loss prevention (DLP).

Correct answer: A

Explanation: Least privilege ensures the application only has the necessary access to both the database and cloud storage, limiting potential damage from compromise. While the other options are important security concepts, least privilege directly addresses the access control aspect of this scenario. Generated by AI

Sample Question 3 — Security Architecture

Your organization is experiencing frequent denial-of-service (DoS) attacks. Which architectural element would be MOST effective in mitigating these attacks?

  1. A. Improved endpoint security.
  2. B. Implementation of a robust intrusion detection system (IDS).
  3. C. Deployment of a content delivery network (CDN). (Correct answer)
  4. D. Strengthening data loss prevention (DLP) measures.

Correct answer: C

Explanation: A CDN distributes traffic across multiple servers, making it harder for DoS attacks to overwhelm a single point of failure. While IDS can detect attacks and endpoint security is crucial, a CDN directly addresses the volume and distribution of traffic issues inherent in DoS attacks. DLP is irrelevant to DoS.

Sample Question 4 — Security Architecture

You are designing the security architecture for a new e-commerce website. Which security control would be MOST effective in preventing unauthorized access to customer credit card information?

  1. A. Strong passwords.
  2. B. Regular security audits.
  3. C. Payment Card Industry Data Security Standard (PCI DSS) compliance. (Correct answer)
  4. D. Intrusion detection systems (IDS).

Correct answer: C

Explanation: PCI DSS specifically addresses the secure handling of credit card data. While the other options are important aspects of overall security, PCI DSS compliance provides a comprehensive framework for securing payment card information. Generated by AI

Sample Question 5 — Security Architecture

Your company is implementing a zero trust security model. Which principle is CENTRAL to this approach?

  1. A. Implicit trust.
  2. B. Network segmentation.
  3. C. Assume breach. (Correct answer)
  4. D. Perimeter security.

Correct answer: C

Explanation: Zero trust operates on the principle of 'never trust, always verify.' It assumes a breach has already occurred and verifies every access request, regardless of location. Network segmentation is part of the implementation, but the core principle is 'assume breach.' Generated by AI

Sample Question 6 — Security Architecture

You're tasked with designing a secure network architecture for a small office. Which topology offers the best balance between security and simplicity?

  1. A. Star topology. (Correct answer)
  2. B. Bus topology.
  3. C. Ring topology.
  4. D. Mesh topology.

Correct answer: A

Explanation: A star topology, with a central switch, provides a good balance of simplicity and security. It's easier to manage and offers better security compared to the other topologies. A failure in one device is usually isolated. Mesh is overly complex for a small office. Generated by AI
