Drag a concept onto its matching description — or click a concept then click the description.
Static public IP that can be remapped to another instance
DNS-based routing to healthy endpoints
Distributes traffic evenly across all registered targets in all AZs
Improves availability and performance using Anycast IPs
Captures IP traffic information for troubleshooting
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Elastic Load Balancer: Distributes incoming traffic across multiple targets to increase fault tolerance.
Correct matches: Elastic Load Balancer distributes traffic, Route 53 provides DNS health checks, and Global Accelerator uses anycast routing. Common confusions: ELB does not handle DNS; Route 53 does not direct traffic over the global network; Global Accelerator does not log traffic.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Elastic Load Balancer: Distributes incoming traffic across multiple targets to increase fault tolerance.
Why this is correct
This correctly describes the purpose of Elastic Load Balancer for high availability and fault tolerance.
Elastic Load Balancer: Routes traffic based on DNS health checks.
Why it's wrong here
Incorrect — DNS-based routing with health checks is a feature of Amazon Route 53, not ELB.
Amazon Route 53: Provides DNS-based routing with health checks to direct traffic to healthy endpoints.
Why this is correct
This correctly describes Route 53's role in high availability through DNS routing and health checks.
Amazon Route 53: Improves application availability by directing traffic over the AWS global network.
Why it's wrong here
Incorrect — directing traffic over the AWS global network using anycast is a feature of AWS Global Accelerator.
AWS Global Accelerator: Uses anycast IP addresses to route traffic to optimal endpoints.
Why this is correct
This correctly describes how Global Accelerator improves availability and fault tolerance.
AWS Global Accelerator: Captures network traffic logs for analysis.
Why it's wrong here
Incorrect — capturing network traffic logs is a function of VPC Flow Logs, not Global Accelerator.
