1.What is the default maximum number of MFA devices in use per AWS account (at the root account level)?

A.1

B.5

C.15

D.10

Answer:A

Explanation:

By default, AWS allows only 1 MFA device to be associated with the root account of an AWS account.

You can add multiple MFA devices for IAM users, but the root account is limited to one MFA device to ensure secure access.

2.Can the string value of ‘Key’ be prefixed with laws?

A.No

B.Only for EC2 not S3

C.Yes

D.Only for S3 not EC

Answer:C

Yes

Explanation:

In AWS, the string value of a key in a tag can be prefixed with “aws:” but only by AWS.

Tags with keys prefixed with aws: are reserved for internal AWS use.
You cannot create or modify tags with keys that begin with “aws:” for your own resources, as they are used for system-defined tags.

3.You nave multiple Amazon EC2 instances running in a cluster across multiple Availability Zones within the same region. What combination of the following should be used to ensure the highest network performance (packets per second), lowest latency, and lowest jitter? Choose 3 answers

A.Amazon EC2 placement groups

B.Enhanced networking

C.Amazon PV AMI

D.Amazon HVM AMI

E.Amazon Linux

F.Amazon VPC

Amazon EC2 placement groups – Placement groups, especially cluster placement groups, are designed to achieve low-latency and high-throughput network performance by placing EC2 instances close to each other.

Enhanced networking – Enhanced networking uses SR-IOV (Single Root I/O Virtualization) to provide higher I/O performance and lower latency for EC2 instances.

Amazon HVM AMI – HVM (Hardware Virtual Machine) AMIs provide better performance than PV (Paravirtual) AMIs, especially when combined with enhanced networking.

4.Are you able to integrate a multi-factor token service with the AWS Platform?

A.Yes, using the AWS multi-factor token devices to authenticate users on the AWS platform.

B.No, you cannot integrate multi-factor token devices with the AWS platform.

C.Yes, you can integrate private multi-factor token devices to authenticate users to the AWS platform.

Send an SNS notification, if configured to do so.
Terminate an instance in the AZ which currently has 2 running EC2 instances.

Explanation:

SNS Notification:
- Auto Scaling can be configured to send an SNS notification when an instance is launched or terminated.
- This allows administrators to monitor and track Auto Scaling activities.
Terminate in the AZ with More Instances:
- By default, Auto Scaling tries to maintain balance across Availability Zones (AZs).
- If there is an imbalance, Auto Scaling terminates instances in the AZ with the highest number of running instances to maintain even distribution.

5.What is one key difference between an Amazon EBS-backed and an instance-store backed instance?

A.Amazon EBS-backed instances can be stopped and restarted.

B.Instance-store backed instances can be stopped and restarted.

C.Auto scaling requires using Amazon EBS-backed instances.

D.Virtual Private Cloud requires EBS backed instances.

Answer:A

Amazon EBS-backed instances can be stopped and restarted.

Explanation:

Amazon EBS-backed instances:
- Can be stopped and restarted without losing data stored on the root volume.
- The root volume is stored on Amazon EBS, which is persistent storage.
Instance-store backed instances:
- Cannot be stopped and restarted — they can only be terminated and data on the instance store is lost when the instance is stopped or terminated.
- The root volume is stored on ephemeral instance storage, which is temporary.
