Question 105:

A) Azure Traffic Manager
B) Application Gateway
C) Standard Load Balancer
D) Azure Firewall

Answer:
A

Explanation:

Azure Traffic Manager is a global DNS-based routing service that directs users to the nearest or healthiest application endpoint. It supports multiple routing methods, including performance-based, priority, weighted, and geographic routing. Traffic Manager continuously monitors endpoint health and automatically reroutes traffic if an endpoint becomes unavailable, ensuring high availability, optimized performance, and minimal user impact. This is crucial for multi-region deployments, disaster recovery, and global applications where latency optimization and reliability are essential.

Option B, Application Gateway, provides regional layer 7 load balancing with WAF capabilities. It cannot perform global DNS-based routing or failover, limiting its usefulness for multi-region, latency-sensitive applications.

Option C, Standard Load Balancer, operates at layer 4 and is region-specific. It cannot provide global routing, endpoint selection based on proximity, or health-based failover across regions.

Option D, Azure Firewall, inspects and filters traffic but does not provide global endpoint routing, latency optimization, or disaster recovery. Its function is security enforcement, not traffic optimization.

Deploying Azure Traffic Manager ensures users connect to the nearest healthy endpoint, minimizing latency and improving responsiveness. It enhances global application availability by automatically rerouting traffic during regional outages. Integration with monitoring tools provides operational visibility, enabling proactive management of traffic patterns, endpoint health, and availability. Traffic Manager supports enterprise best practices for high-performance, globally distributed applications, ensuring operational continuity, reliability, and superior user experience. It is critical for multi-region deployment strategies, disaster recovery planning, and optimized global performance in enterprise-scale cloud environments.
