AWS Certified SysOps Administrator – Associate (legacy) — Question 74

A user has configured ELB with three instances. The user wants to achieve High Availability as well as redundancy with ELB. Which of the below mentioned AWS services helps the user achieve this for ELB?

Answer options

• A. Route 53
• B. AWS Mechanical Turk
• C. Auto Scaling
• D. AWS EMR

Correct answer: A

Explanation

Route 53 can route traffic across multiple instances, providing DNS failover and health checks, which enhances High Availability and redundancy for ELB. The other options, such as AWS Mechanical Turk, Auto Scaling, and AWS EMR, do not specifically address the routing and availability needs of the ELB setup in this context.
