Question 670

A company places two redundant application servers in one Availability Zone and calls that zone fault tolerance. Which underlying reason BEST explains the recommended choice?

  1. Edge locations provide selected network and caching functions rather than every regional service.
  2. Multiple machines inside one AZ can still share the same zone failure domain.
  3. Edge caches can serve eligible content near viewers while origins remain elsewhere.
  4. Regions are distinct geographic locations and matter for data location and supported services.

Explanation

Correct Answer

B:

Multiple machines inside one AZ can still share the same zone failure domain. This principle explains why the suitable decision is: Use more than one AZ when the business requires protection from an AZ outage. The confirming observation would be: A simulated AZ outage leaves at least one healthy instance in another AZ.
