CompTIA Updated CAS-005 Exam Questions and Answers by ayub

In serverless computing, organizations rely heavily on CSPs to manage the infrastructure, runtime, and scaling. A key risk is thelevel of control and influence governments have over CSPs, potentially affecting availability, access, or confidentiality of hosted services due to legal orders or government actions. Concerns about virtualization technologies, scalability, or third-party monitoring are valid but less critical compared to the overarching legal and control risks tied to CSP reliance.

The question focuses oninternet-facing hosts, implying external exposure. CVSS scores, remote executability, and exploitavailability guide prioritization. Server2 (205.1.3.5, CVSS 6.5, Bind Server) has a public IP, suggesting it’s internet-facing, unlike Server1 and Server4 (192.168.x.x, private IPs). Server3 (207.1.5.7, CVSS 5.5) is also public but has a lower score and risk compared to Server2’s proof-of-concept (POC) exploit. Server2’s Bind Server (DNS) role is critical and commonly targeted, making it the priority.

Option A:Server1 (CVSS 7.5) is private, not internet-facing.

Option B:Server2 (CVSS 6.5) is internet-facing with an exploit POC, warranting immediate patching.

Option C:Server3 (CVSS 5.5) is internet-facing but less severe.

Option D:Server4 (CVSS 9.8) is critical but private, not internet-facing.

Phishing simulations are a proven method for reinforcing security awareness, meeting compliance training requirements, and improving user incident reporting. In CAS-005, social engineering testing is a recommended component of organizational security culture programs.

DoS attacks (A) and penetration tests (B) assess technical security, not user awareness.

Fake ransomware (D) can cause unnecessary alarm and operational disruption.

The best location to test a newly released feature for an internal application, without affecting the production environment, is the staging environment. Here’s a detailed explanation:

Staging Environment: This environment closely mirrors the production environment in terms of hardware, software, configurations, and settings. It serves as a final testing ground before deploying changes to production. Testing in the staging environment ensures that the new feature will behave as expected in the actual production setup.

Isolation fromProduction: The staging environment is isolated from production, which means any issues arising from the new feature will not impact the live users or the integrity of the production data. This aligns with best practices in change management and risk mitigation.

Realistic Testing: Since the staging environment replicates the production environment, it provides realistic testing conditions. This helps in identifying potential issues that might not be apparent in a development or testing environment, which often have different configurations and workloads.
