2.Common points of failures like generators and cooling equipment are shared across Availability Zones.

A.TRUE

B.FALSE

Answer:B

FALSE

In AWS, Availability Zones (AZs) are designed to be independent and isolated from each other to improve fault tolerance. Each AZ has its own power, cooling, and networking infrastructure to minimize shared points of failure. This ensures that failures in one AZ do not impact others.

3.Within the IAM service a GROUP is regarded as a

A.A collection of AWS accounts

B.It’s the group of EC2 machines that gain the permissions specified in the GROUP.

C.There’s no GROUP in IAM, but only USERS and RESOURCES.

D.A collection of users.

Answer:D

A collection of users.

In AWS Identity and Access Management (IAM), a Group is a collection of IAM users that share the same permissions. Instead of assigning policies to individual users, you can assign permissions to a Group, and all users within that group inherit the permissions.

This simplifies permission management and ensures consistent access control across multiple users.

4.Does AWS Direct Connect allow you access to all Availabilities Zones within a Region?

A.Depends on the type of connection

B.No

C.Yes

D.Only when there’s just one availability zone in a region. If there are more than one, only one availability zone can be accessed directly.

Answer:C

Yes

AWS Direct Connect provides a dedicated network connection from your on-premises data center to AWS and allows access to all Availability Zones within a Region. Once connected, you can route traffic to any AZ within that region, as long as you have the necessary VPC configurations in place (such as using AWS Direct Connect Gateway for multi-region access).

5.Which services allow the customer to retain full administrative privileges of the underlying EC2 instances?

A.Amazon Relational Database Service

B.Amazon Elastic Map Reduce

C.Amazon ElastiCache

D.Amazon DynamoDB

E.AWS Elastic Beanstalk

Answer: B & E

Amazon Elastic MapReduce (EMR) and AWS Elastic Beanstalk

Explanation:

Amazon EMR: Customers retain full administrative access to the underlying EC2 instances in an EMR cluster. You can SSH into the instances, install software, and manage configurations.
AWS Elastic Beanstalk: While Elastic Beanstalk manages deployments, it still provides full control over the underlying EC2 instances, allowing users to modify configurations and access the instances directly.
