MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Zone-redundant services (ZRS): With zone-redundant services, replication of data is performed automatically to protect resources from single points of failure. Zone redundant storage, for example, replicates the data across three zones so that a zone failure won’t impact the high availability of the data.

Detailed explanation-2: -Elastic Load Balancer allows the incoming traffic to be distributed automatically across multiple healthy EC2 instances.

Detailed explanation-3: -Availability zones can be used to spread a solution across multiple zones within a region, allowing for an application to continue functioning when one zone fails. With availability zones, Azure offers industry best 99.99% Virtual Machine (VM) uptime service-level agreement (SLA).

Detailed explanation-4: -Ramping Up AWS Redundancy AZs are insulated from the failures of other zones in the group, making them a simple form of redundancy. By replicating your EC2 instance across multiple AZs, you significantly reduce the chance of total outage or failure.
