2.You have an EC2 Security Group with several running EC2 instances. You change the Security Group rules to allow inbound traffic on a new port and protocol, and launch several new instances in the same Security Group. The new rules apply:

A.Immediately to all instances in the security group.

B.Immediately to the new instances only.

C.Immediately to the new instances, but old instances must be stopped and restarted before the new rules apply.

D. To all instances, but it may take several minutes for old instances to see the changes.

Answer:A

Immediately to all instances in the security group.

Explanation:

When you modify security group rules (such as allowing traffic on a new port or protocol), the changes are applied immediately to all instances associated with that security group.
Security groups are stateful, so inbound and outbound rules are dynamically applied without requiring the instances to be restarted.
New instances launched in the same security group will also inherit these updated rules automatically.

3.You launch an Amazon EC2 instance without an assigned AVVS identity and Access Management (IAM) role. Later, you decide that the instance should be running with an IAM role. Which action must you take in order to have a running Amazon EC2 instance with an IAM role assigned to it?

A.Create an image of the instance, and register the image with an IAM role assigned and an Amazon EBS volume mapping.

B.Create a new IAM role with the same permissions as an existing IAM role, and assign it to the running instance.

C.Create an image of the instance, add a new IAM role with the same permissions as the desired IAM role, and deregister the image with the new role assigned.

D.Create an image of the instance, and use this image to launch a new instance with the desired IAM role assigned.

Answer:D

Create an image of the instance, and use this image to launch a new instance with the desired IAM role assigned.

Explanation:

If an EC2 instance is launched without an IAM role, you cannot assign an IAM role to it after launch directly.
To assign an IAM role to an instance:
1. Create an image (AMI) of the running instance.
2. Launch a new instance using that image.
3. Assign the desired IAM role during the launch process.

4.A customer needs corporate IT governance and cost oversight of all AWS resources consumed by its divisions. The divisions want to maintain administrative control of the discrete AWS resources they consume and keep those resources separate from the resources of other divisions. Which of the following options, when used together will support the autonomy/control of divisions while enabling corporate IT to maintain governance and cost oversight?

Choose 2 answers

A.Use AWS Consolidated Billing and disable AWS root account access for the child accounts.

B.Enable IAM cross-account access for all corporate IT administrators in each child account.

C.Create separate VPCs for each division within the corporate IT AWS account.

D.Use AWS Consolidated Billing to link the divisions’ accounts to a parent corporate account.

E.Write all child AWS CloudTrail and Amazon CloudWatch logs to each child account’s Amazon S3 ‘Log’ bucket.

Enable IAM cross-account access for all corporate IT administrators in each child account.
Use AWS Consolidated Billing to link the divisions’ accounts to a parent corporate account.

Explanation:

IAM Cross-Account Access:
- This allows corporate IT administrators to centrally manage security, compliance, and governance by accessing child accounts while allowing divisions to maintain administrative control over their own AWS resources.
AWS Consolidated Billing:
- Consolidated Billing combines the bills of multiple AWS accounts into one account, giving corporate IT cost oversight while maintaining division-level autonomy.
- It also provides volume discounts and helps track spending across multiple accounts.

C.one

D.reserved

Answer:A
