Question 101

A company's Security Engineer is copying all application logs to centralized Amazon S3 buckets. Currently, each of the company's applications is in its own IAM account, and logs are pushed into S3 buckets associated with each account. The Engineer will deploy an IAM Lambda function into each account that copies the relevant log files to the centralized S3 bucket.

The Security Engineer is unable to access the log files in the centralized S3 bucket. The Engineer's IAM user policy from the centralized account looks like this:

Questions 101

The centralized S3 bucket policy looks like this:

Questions 101

Why is the Security Engineer unable to access the log files?

Options:

The S3 bucket policy does not explicitly allow the Security Engineer access to the objects in the bucket.

The object ACLs are not being updated to allow the users within the centralized account to access the objects

The Security Engineers IAM policy does not grant permissions to read objects in the S3 bucket

The s3:PutObject and s3:PutObjectAcl permissions should be applied at the S3 bucket level

Question 102

A business stores website images in an Amazon S3 bucket. The firm serves the photos to end users through Amazon CloudFront. The firm learned lately that the photographs are being accessible from nations in which it does not have a distribution license.

Which steps should the business take to safeguard the photographs and restrict their distribution? (Select two.)

Options:

Update the S3 bucket policy to restrict access to a CloudFront origin access identity (OAI).

Update the website DNS record to use an Amazon Route 53 geolocation record deny list of countries where the company lacks a license.

Add a CloudFront geo restriction deny list of countries where the company lacks a license.

Update the S3 bucket policy with a deny list of countries where the company lacks a license.

Enable the Restrict Viewer Access option in CloudFront to create a deny list of countries where the company lacks a license.

Question 103

A company is designing a new application stack. The design includes web servers and backend servers that are hosted on Amazon EC2 instances. The design also includes an Amazon Aurora MySQL DB cluster.

The EC2 instances are m an Auto Scaling group that uses launch templates. The EC2 instances for the web layer and the backend layer are backed by Amazon Elastic Block Store (Amazon EBS) volumes. No layers are encrypted at rest. A security engineer needs to implement encryption at rest.

Which combination of steps will meet these requirements? (Select TWO.)

Options:

Modify EBS default encryption settings in the target AWS Region to enable encryption. Use an Auto Scaling group instance refresh.

Modify the launch templates for the web layer and the backend layer to add AWS Certificate Manager (ACM) encryption for the attached EBS volumes. Use an Auto Scaling group instance refresh.

Create a new AWS Key Management Service (AWS KMS) encrypted DB cluster from a snapshot of the existing DB cluster.

Apply AWS Key Management Service (AWS KMS) encryption to the existing DB cluster.

Apply AWS Certificate Manager (ACM) encryption to the existing DB cluster.

Answer:

A, C

Explanation:

Explanation:

https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Overview.Encryption.html

https://aws.amazon.com/premiumsupport/knowledge-center/ebs-automatic-encryption/

To implement encryption at rest for both the EC2 instances and the Aurora DB cluster, the following steps are required:

For the EC2 instances, modify the EBS default encryption settings in the target AWS Region to enable encryption. This will ensure that any new EBS volumes created in that Region are encrypted by default using an AWS managed key. Alternatively, you can specify a customer managed key when creating new EBS volumes. For more information, see Amazon EBS encryption.
Use an Auto Scaling group instance refresh to replace the existing EC2 instances with new ones that have encrypted EBS volumes attached. An instance refresh is a feature that helps you update all instances in an Auto Scaling group in a rolling fashion without the need to manage the instance replacement process manually. For more information, see Replacing Auto Scaling instances based on an instance refresh.
For the Aurora DB cluster, create a new AWS Key Management Service (AWS KMS) encrypted DB cluster from a snapshot of the existing DB cluster. You can use either an AWS managed key or a customer managed key to encrypt the new DB cluster. You cannot enable or disable encryption for an existing DB cluster, so you have to create a new one from a snapshot. For more information, see Encrypting Amazon Aurora resources.

The other options are incorrect because they either do not enable encryption at rest for the resources (B, D), or they use the wrong service for encryption (E).

Best Dumps among other dumps providers. I like it so much because of their authenticity.

Kaiden Sep 16, 2024

That's great. I've used other dump providers in the past and they were often outdated or had incorrect information. This time I will try it.
