Question 181

You are the AWS cloud architect and have been tasked with designing an appropriate subnetting design for your production VPC. Your production VPC requires secure communications back to the corporate private network. Quality of Service (QoS) is very important 24 ◊ 7 for this particular connection, as real-time data is passed continually backwards and forwards between your on-prem bioinformatics enterprise application, and the number crunching servers deployed in the cloud. Any potential latency incurred on this connection will have a direct impact on the company's ability to attract investors and expansion into new markets. Select the correct network configuration that best facilitates your company's continued growth plans.

Question 187

A global film production company uses the AWS Cloud to encode and store its video content before distribution. The company's three global offices are connected to the us-east-1 Region through AWS Site-to-Site VPN links that terminate on a transit gateway with BGP routing activated.

The company recently started to produce content at a higher resolution to support 8K streaming.

Uploads of files to Amazon EC2 instances are taking 10 times longer than they did with the previous format.

Which actions should a network engineer recommend to reduce the upload times? (Choose two.)

Create a second VPN tunnel from each office location to the transit gateway. Activate equal-cost multi-path (ECMP) routing.

Modify the transit gateway to activate Jumbo MTU on the VPN tunnels to each office location.

Replace the existing VPN tunnels with new tunnels that have acceleration activated.

Upgrade each EC2 instance to a modern instance type. Activate Jumbo MTU in the operating system.

Replace the existing VPN tunnels with new tunnels that have IGMP activated.

Question 189

You operate a production VPC with both a public and a private subnet. Your organization maintains a restricted Amazon S3 bucket to support this production workload. Only Amazon EC2 instances in the private subnet should access the bucket. You implement VPC endpoints (VPC-E) for Amazon S3 and remove the NAT that previously provided a network path to Amazon S3. The default VPC-E policy is applied. Neither EC2 instances in the public or private subnets are able to access the S3 bucket.

What should you do to enable Amazon S3 access from EC2 instances in the private subnet?

Add the CIDR address range of the private subnet to the S3 bucket policy.

Add the VPC-E identifier to the S3 bucket policy.

Add the VPC identifier for the production VPC to the S3 bucket policy.

Add the VPC-E identifier for the production VPC to endpoint policy.
