Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

What best describes the purpose of having many Availability Zones in each AWS region?

A	Allow for fault tolerance but not high availability.
B	Allow for cheaper prices due to competition between them.
C	Allow for duplicate and redundant compute, and data backups.
D	None of the above

Explanation:

Detailed explanation-1: -Which statement best describes Availability Zones? Distinct locations from within an AWS region that are engineered to be isolated from failures.

Detailed explanation-2: -Which statement BEST describes the relationship between Regions, Availability Zones and data centers? Regions are clusters of Availability Zones.

Detailed explanation-3: -Within the constructs of AWS, customers are encouraged to run their workloads in more than one Availability Zone. This ensures that customer applications can withstand even a complete Availability Zone failure-a very rare event in itself. This recommendation stands for real-time SIP infrastructure as well.

Detailed explanation-4: -Availability Zones are distinct locations within an AWS Region that are engineered to be isolated from failures in other Availability Zones. They provide inexpensive, low-latency network connectivity to other Availability Zones in the same AWS Region.
