Question 14. Securing DNS in cloud environments involves: A) Disabling DNS services B) Using DNSSEC to verify DNS responses C) Blocking all DNS traffic
D) Using only internal DNS servers without validation Answer: B Explanation: DNSSEC adds cryptographic signatures to DNS responses, ensuring authenticity and preventing DNS spoofing attacks. Question 15. Load balancing in cloud environments can have security implications primarily because: A) It reduces latency only B) It exposes backend servers to direct internet access if misconfigured C) It encrypts all traffic automatically D) It eliminates the need for firewalls Answer: B Explanation: Misconfigured load balancers can expose backend servers directly to the internet, increasing attack surface if proper security measures are not in place. Question 16. Which data security measure involves converting data into an unreadable format to prevent unauthorized access? A) Data masking B) Data encryption
C) Backup data automatically D) Harden cloud databases Answer: B Explanation: DLP tools monitor data movement and prevent sensitive data from leaving the organization unauthorized. Question 19. Which technique involves replacing sensitive data with fictitious but realistic data for testing or analysis? A) Data masking B) Data encryption C) Data classification D) Data retention Answer: A Explanation: Data masking conceals actual data by replacing it with similar, non-sensitive data for secure testing or analysis. Question 20. Cloud storage security best practices include: A) Keeping default permissions B) Regularly reviewing and adjusting access controls C) Disabling logging
D) Avoiding encryption for better performance Answer: B Explanation: Regular review of access controls ensures only authorized users have access, reducing the risk of data breaches. Question 21. Which cloud database security measure involves configuring database permissions to restrict access based on user roles? A) Role-Based Access Control (RBAC) B) Data encryption at rest C) Data masking D) Firewall rules Answer: A Explanation: RBAC assigns permissions based on user roles, ensuring users can only access data necessary for their responsibilities. Question 22. Data classification in the cloud helps organizations to: A) Define storage locations for data B) Determine security controls based on data sensitivity C) Automate data backups D) Improve network throughput
Answer: B Explanation: Incorporating security into the SDLC ensures vulnerabilities are addressed early, reducing risk in cloud applications. Question 25. The OWASP Top 10 highlights common web application vulnerabilities. Which of these is a primary concern in cloud applications?
