Basic understanding of cybersecurity Answer: Technical expertise in network management (A) Specialized personnel are required to effectively manage and troubleshoot GSLB systems. 4. What potential risk must be addressed during the implementation of a GSLB system? A. Increase in server efficiency B. Security concerns from potential attacks C. Enhanced user engagement D. Easier data integration processes Answer: Security concerns from potential attacks (B) Implementing GSLB necessitates protecting the system against malicious attacks. 5. Which aspect is crucial for maintaining smooth user experience with GSLB? A. Health monitoring and efficient routing B. Greater initial hardware investment C. Reduced server availability D. Increased server complexity Answer: Health monitoring and efficient routing (A) A well-designed GSLB system focuses on health monitoring and efficient routing to ensure optimal performance. 6. What is the primary goal of Global Server Load Balancing (GSLB)? A. To increase server hardware capacity B. To reduce the number of servers needed C. To improve application availability and performance D. To enforce strict security measures Answer: To improve application availability and performance (C) GSLB aims to distribute user requests to enhance application availability, performance, and scalability. 7. Which mechanism does GSLB use to ensure traffic is only directed to functioning servers? A. Caching B. Load balancing C. Traffic smoothing D. Health checks Answer: Health checks (D) Health checks are essential for monitoring server availability and ensuring high service quality. 8. How does GSLB minimize response times for users? A. By increasing server capacity B. By caching all server data C. By routing to the closest server based on user location D. By limiting server access only to authorized users Answer: By routing to the closest server based on user location (C) GSLB routes requests to geographically closest servers, effectively reducing latency. 9. What role does DNS play in GSLB? A. It manages server health checks B. It routes user requests to appropriate servers C. It enhances server security D. It stores frequently accessed data Answer: It routes user requests to appropriate servers (B) GSLB commonly uses DNS to intelligently route user requests. 10. Which of the following is essential for maintaining GSLB functionality? A. Reduced server monitoring B. A single server configuration C. Robust network infrastructure D. Limited geographic coverage Answer: Robust network infrastructure (C) A robust network infrastructure is crucial for handling increased traffic volume in GSLB. 11. What is a key benefit of employing a failover mechanism in GSLB? A. Continuous service during server failures B. Higher chances of server downtime C. Increased server load D. Reduced application performance Answer: Continuous service during server failures (A) Failover mechanisms ensure uninterrupted service by redirecting traffic if a server becomes unavailable. 12. What type of solution is GSLB primarily classified as? A. Database management solution B. Client-side solution C. DNS-based and IP-based network solution D. Cloud computing solution Answer: DNS-based and IP-based network solution (C) GSLB employs both DNS and IP network-layer protocols for routing requests. 13. Which of the following strategies is NOT typically associated with GSLB? A. Traffic smoothing B. Health monitoring of servers C. Increased latency for users D. Centralized server management Answer: Increased latency for users (C) GSLB aims to decrease latency, hence increased latency is not a strategy associated with it.
