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.

Provision a Direct Connect connection - between your service provider's data center and the AWS region that your cloud compute resources exist in. Configure just a Private Virtual Interface. As this is a Direct Connection, a Virtual Private Gateway is not required

Suggested answer: D

Explanation:

Explanation:

Answers A, B, and C all rely on an Internet connection. An Internet connection cannot guarantee QoS and will be subject to performance fluctuations - therefore they are all incorrect options. The only difference between these options is whether a Virtual Private Gateway is required - the answer is yes and therefore the correct answer is D.

You can exchange traffic between the two ports in the same region connecting to different Virtual Private Gateways (VGWs) if you have more than one virtual interface.
Suggested answer: D

Explanation:

Explanation:

You must create a virtual interface to begin using your AWS Direct Connect connection. You can create a public virtual interface to connect to public resources or a private virtual interface to connect to your VPC. Also, it is possible to configure multiple virtual interfaces on a single AWS Direct Connect connection, and you'll need one private virtual interface for each VPC to connect to. Each virtual interface needs a VLAN ID, interface IP address, ASN, and BGP key. To use your AWS Direct Connect connection with another AWS account, you can create a hosted virtual interface for that account. These hosted virtual interfaces work the same as standard virtual interfaces and can connect to public resources or a VPC.

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. The size of the content files has increased to three times the size of the content files from the previous format. 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.

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.
