Practice Test 4 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
A Solutions Architect is designing a solution to store and archive corporate documents and has determined that Amazon Glacier is the right solution. Data has to be retrieved within 3-5 hrs as directed by the management.
Which feature in Amazon Glacier can help meet this requirement and ensure cost-effectiveness?
A. Enable Amazon Redshift Enhanced VPC Routing.
B. Create a Cluster Security Group to allow the Amazon Redshift cluster to access Amazon S3.
C. Create a NAT gateway in a public subnet to allow the Amazon Redshift cluster to access Amazon S3.
D. Create and configure an Amazon S3 VPC endpoint.
Explanation:
Correct Answer – A and D
Amazon Redshift Enhanced VPC Routing provides VPC resources access to Redshift.
Redshift will not be able to access the S3 VPC endpoints without enabling Enhanced VPC routing. So one option will not support the scenario if another is not selected.
NAT instance (the proposed answer) cannot be reached by Redshift without enabling Enhanced VPC Routing.
Option D:
- VPC Endpoints – It enables you to privately connect your VPC to the supported AWS Services and VPC Endpoint services powered by PrivateLink without requiring an IGW, NAT Device, VPN Connection or AWS Direct Connect connections. Instances in VPC do not require Public IP addresses to communicate with resources in the service and traffic between your VPC and other service does not leave the Amazon network.
- S3 VPC Endpoint – it is a feature that will allow you to make even better use of VPC and S3.
