NEW QUESTION # 800
A company creates operations data and stores the data in an Amazon S3 bucket for the company's annual audit, an external consultant needs to access an annual report that is stored in the S3 bucket. The external consultant needs to access the report for 7 days.
The company must implement a solution to allow the external consultant access to only the report.
Which solution will meet these requirements with the MOST operational efficiency?

  • A. Create a new S3 bucket that is configured to host a public static website. Migrate the operations data to the new S3 bucket. Share the S3 website URL with the external consultant.
  • B. Enable public access to the S3 bucket for 7 days. Remove access to the S3 bucket when the external consultant completes the audit.
  • C. Create a new 1AM user that has access to the report in the S3 bucket. Provide the access keys to the external consultant. Revoke the access keys after 7 days.
  • D. Generate a presigned URL that has the required access to the location of the report on the S3 bucket.Share the presigned URL with the external consultant.

Answer: D

Explanation:
A presigned URL allows temporary access to a specific object in an S3 bucket without needing to make the bucket public or creating and managing additional IAM users. The URL is time-limited, and permissions are granted only to the specific object (in this case, the annual report), making it a highly secure and operationally efficient solution.
With a presigned URL, the consultant can access the report for the specified duration (7 days), after which the URL will expire automatically, removing the need for manual intervention to revoke access.
AWS References:
* Amazon S3 Presigned URLs explain how to generate a presigned URL to grant temporary access to S3 objects.
* Best Practices for S3 Security emphasize using presigned URLs for sharing temporary access to S3 objects securely.
Why the other options are incorrect:
* A. Public static website: This approach involves making the S3 bucket publicly accessible, which is unnecessary and insecure for sensitive data.
* B. Enable public access: Granting public access to the entire bucket, even temporarily, is a security risk and violates best practices.
* C. Create an IAM user: Creating an IAM user and managing credentials is unnecessary overhead and less secure compared to a presigned URL for this short-term need.


NEW QUESTION # 801
A company recently signed a contract with an AWS Managed Service Provider (MSP) Partner for help with an application migration initiative. A solutions architect needs to share an Amazon Machine Image (AMI) from an existing AWS account with the MSP Partner's AWS account. The AMI is backed by Amazon Elastic Block Store (Amazon EBS) and uses a customer managed customer master key (CMK) to encrypt EBS volume snapshots.
What is the MOST secure way for the solutions architect to share the AMI with the MSP Partner's AWS account?

  • A. Make the encrypted AMI and snapshots publicly available. Modify the CMK's key policy to allow the MSP Partner's AWS account to use the key
  • B. Export the AMI from the source account to an Amazon S3 bucket in the MSP Partner's AWS account.
    Encrypt the S3 bucket with a CMK that is owned by the MSP Partner Copy and launch the AMI in the MSP Partner's AWS account.
  • C. Modify the launchPermission property of the AMI Share the AMI with the MSP Partner's AWS account only. Modify the CMK's key policy to trust a new CMK that is owned by the MSP Partner for encryption.
  • D. Modify the launchPermission property of the AMI. Share the AMI with the MSP Partner's AWS account only. Modify the CMK's key policy to allow the MSP Partner's AWS account to use the key.

Answer: D

Explanation:
Explanation
Share the existing KMS key with the MSP external account because it has already been used to encrypt the AMI snapshot.

NEW QUESTION # 802
A Solutions Architect identified a series of DDoS attacks while monitoring the VPC. The Architect needs to fortify the current cloud infrastructure to protect the data of the clients.
Which of the following is the most suitable solution to mitigate these kinds of attacks?

  • A. Using the AWS Firewall Manager, set up a security layer that will prevent SYN floods, UDP reflection attacks, and other DDoS attacks.
  • B. Set up a web application firewall using AWS WAF to filter, monitor, and block HTTP traffic.
  • C. A combination of Security Groups and Network Access Control Lists to only allow authorized traffic to access your VPC.
  • D. Use AWS Shield Advanced to detect and mitigate DDoS attacks.

Answer: D

Explanation:
For higher levels of protection against attacks targeting your applications running on Amazon Elastic Compute Cloud (EC2), Elastic Load Balancing(ELB), Amazon CloudFront, and Amazon Route 53 resources, you can subscribe to AWS Shield Advanced. In addition to the network and transport layer protections that come with Standard, AWS Shield Advanced provides additional detection and mitigation against large and sophisticated DDoS attacks, near real-time visibility into attacks, and integration with AWS WAF, a web application firewall.

AWS Shield Advanced also gives you 24x7 access to the AWS DDoS Response Team (DRT) and protection against DDoS related spikes in your Amazon Elastic Compute Cloud (EC2), Elastic Load Balancing(ELB), Amazon CloudFront, and Amazon Route 53 charges.
Hence, the correct answer is: Use AWS Shield Advanced to detect and mitigate DDoS attacks.
The option that says: Using the AWS Firewall Manager, set up a security layer that will prevent SYN floods, UDP reflection attacks and other DDoS attacks is incorrect because AWS Firewall Manager is mainly used to simplify your AWS WAF administration and maintenance tasks across multiple accounts and resources. It does not protect your VPC against DDoS attacks.
The option that says: Set up a web application firewall using AWS WAF to filter, monitor, and block HTTP traffic is incorrect. Even though AWS WAF can help you block common attack patterns to your VPC such as SQL injection or cross-site scripting, this is still not enough to withstand DDoS attacks. It is better to use AWS Shield in this scenario.
The option that says: A combination of Security Groups and Network Access Control Lists to only allow authorized traffic to access your VPC is incorrect. Although using a combination of Security Groups and NACLs are valid to provide security to your VPC, this is not enough to mitigate a DDoS attack. You should use AWS Shield for better security protection. References:
