Question 1

A company provisions an AWS Direct Connect connection to permit access to Amazon EC2 resources in several Amazon VPCs and to data stored in private Amazon S3 buckets. The Network Engineer needs to configure the company's on-premises router for this Direct Connect connection.

Which of the following actions will require the LEAST amount of configuration overhead on the customer router?

A : nfigure private virtual interfaces for the VPC resources and for Amazon S3.

B : nfigure private virtual interfaces for the VPC resources and a public virtual interface for Amazon S3.

C : nfigure a private virtual interface to a Direct Connect gateway for the VPC resources and for Amazon S3

D : nfigure a private virtual interface to a Direct Connect gateway for the VPC resources and a public virtual interface for Amazon S3.

Answer: A

Question 2

A company deployed an application in two AWS Regions in one AWS account. The company has one VPC in each Region. The VPCs use non-overlapping private CIDR ranges. The company needs to connect both VPCs to a single on-premises data center to test the application. The application requires up to 800 Mbps of throughput. A network engineer needs to establish connectivity between the VPCs and the on-premises data center. Which solution will meet this requirement with the LEAST operational overhead?

A : Order a 2 Gbps Direct Connect connection for the data center. Configure a virtual private gateway in each VPC. Create a private VIF for each virtual private gateway, and associate the virtual private gateways with the Direct Connect connection. Configure static routes in the VPC route tables and in the data center router.

B : Order a 2 Gbps Direct Connect connection for the data center. Configure a virtual private gateway in each VPC. Create a private VIF for each virtual private gateway, and associate the virtual private gateways with the Direct Connect connection. Configure Open Shortest Path First (OSPF) routing between the private VIF and the data center.

C : Configure a customer gateway and a virtual private gateway in each VPC. Configure an AWS SitetoSite VPN connection between the data center and each VPC. Configure static routes in each VPC route table to point to the subnets in the data center.

D : Configure a customer gateway and a virtual private gateway in each VPC. Configure an AWS SitetoSite VPN connection between the data center and each VPC. Configure BGP routing between the VPCs and the data center.

Answer: A

Question 3

A company has an application running on Amazon EC2 instances in a VPC The application must publish custom metrics to Amazon CloudWatch in the same AWS Region The metrics include proprietary information All connectivity must be over private IP addresses.

Which solution will meet these requirements'?

A : nnect to CloudWatch through a NAT gateway

B : nnect to CloudWatch through a gateway endpoint

C : nnect to CloudWatch through an internet gateway

D : nnect to CloudWatch through an interface endpoint

Answer: D

Question 4

A department in your company has created a new account that is not part of the organization's consolidated billing family. The department has also created a VPC for its workload. Access is restricted by network access control lists to the department's on-premises private IP allocation. An AWS Direct Connect private virtual interface for this VPC advertises a default route to the company network. When the department downloads data from an Amazon Elastic Compute Cloud(EC2) instance in its new VPC, what are the associated charges?

A : company pays Internet Data Out charges.

B : company pays AWS Direct Connect Data Out charges.

C : department pays Internet Data Out charges.

D : department pays AWS Direct Connect Data Out charges.

Answer: D

Question 5

A company runs workloads in multiple VPCs. The company needs to securely access a workload in one of the VPCs, named VPC-A, from an on-premises data center. A network engineer sets up an AWS Site-to-Site VPN connection to a transit gateway. The network engineer configures dynamic routing for the connection, and communication works properly. Recently, the owner of VPC-A added another CIDR range to the VPC. The VPC-A owner created workloads that use the additional CIDR range. The company's on-premises network is unable to reach the new workloads. The network engineer needs to resolve the network connectivity issue and ensure that connectivity will not be affected if additional VPC CIDR ranges are added to the VPC in the future. Which solution will meet these requirements with the MOST operational efficiency?

A : Configure route propagation for VPC-A to the VPN attachment route table.

B : Manually update the VPN attachment route table to include the new CIDR range.

C : Configure an Amazon EventBridge rule to invoke an AWS Lambda function when the rule to matches an update to the VPC-A CIDR range. Configure the Lambda function to update the VPN attachment route table.

D : Configure an Amazon CloudWatch alarm to invoke an AWS Lambda function when there is an update to the VPC-A CIDR range. Configure the Lambda function to update the VPN attachment route table. Restart the VPN tunnels.

Answer: A
