MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A region can have multiple availability zones, but no availability zones are shared with different regions. Participating data centers in an availability zone connect to each other over a redundant, high-speed, low-latency private network link, and all zones in a region connect through the same sort of network links.

Detailed explanation-2: -Each AWS region is isolated and operates independently from other regions but the availability zones within each region are connected via low-latency links to provide replication and fault tolerance.

Detailed explanation-3: -The statement “A region always contains two availability zones” is false because regions will contain at least two availability zones, not exactly two.

Detailed explanation-4: -All Availability Zones (AZs) are interconnected with high-bandwidth, low-latency networking, over fully redundant and dedicated metro fiber. This results in single-digit millisecond latency between resources in different Availability Zones in the same Region.

Detailed explanation-5: -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. Each region is completely independent.
