CompTIA CASP+ (CAS-004) — Question 196

A company has moved its sensitive workloads to the cloud and needs to ensure high availability and resiliency of its web-based application. The cloud architecture team was given the following requirements:

• The application must run at 70% capacity at all times
• The application must sustain DoS and DDoS attacks.
• Services must recover automatically.

Which of the following should the cloud architecture team implement? (Choose three.)

Answer options

• A. Read-only replicas
• B. BCP
• C. Autoscaling
• D. WAF
• E. CDN
• F. Encryption
• G. Continuous snapshots
• H. Containerization

Correct answer: C, D, E

Explanation

The correct answers are C, D, and E. Autoscaling (C) allows the application to adjust its capacity dynamically, ensuring it remains at 70% utilization. A Web Application Firewall (WAF) (D) protects against DoS and DDoS attacks, while a Content Delivery Network (CDN) (E) helps distribute traffic and mitigate the effects of such attacks. The other options do not directly address the requirements for high availability and resilience under attack.
