AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 199

You have two public applications on different domains that use two front-end servers and two back-end servers each. You wish to achieve high availability for both applications. What two options should you configure? (Choose two.)

Answer options

• A. Route 53: 2 public zones and 2 private zones.
• B. Route 53: 2 public zones and 1 private zone.
• C. 3 load balancers: 2 public and 1 internal.
• D. 4 load balancers: 2 public and 2 internal.

Correct answer: A, D

Explanation

The correct choices are A and D. Configuring 2 public zones and 2 private zones in Route 53 (A) allows for redundancy and management of traffic effectively across both applications. Additionally, having 4 load balancers with 2 public and 2 internal (D) ensures that there is sufficient load distribution and failover capabilities, while the other options do not provide the necessary redundancy.
