CompTIA CASP+ (CAS-004) — Question 321

A company’s Chief Information Security Officer wants to prevent the company from being the target of ransomware. The company’s IT assets need to be protected. Which of the following are the MOST secure options to address these concerns? (Choose three.)

Answer options

• A. Antivirus
• B. EDR
• C. Sandboxing
• D. Application control
• E. Host-based firewall
• F. IDS
• G. NGFW
• H. Strong authentication

Correct answer: B, C, D

Explanation

The correct answers are B, C, and D because EDR provides advanced threat detection and response capabilities, Sandboxing allows untrusted applications to be executed in a secure environment, and Application control restricts which applications can run, reducing the attack surface. The other options, while useful, do not provide the same level of proactive protection specifically against ransomware.
