The network engineer discovers that the EC2 instances are still able to resolve DNS requests by using Amazon DNS servers inside the VPC Why is the solution tailing to meet the compliance requirement9

A : The security group cannot filter outbound traffic to the Amazon DNS servers

B : The security group must have inbound rules to prevent DNS requests from coming back to EC2 instances.

C : The EC2 instances are using the HTTPS port to send DNS queries to Amazon DNS servers

D : The security group cannot filter outbound traffic to destinations within the same VPC

Answer: A

Question 2

A company has configured an AWS Cloud WAN core network with edge locations in the us-east-1 Region and the us-west-1 Region. Each edge location has two segments: development and staging. The segments use the default core network policy. The company has attached VPCs to the core network. A development VPC is attached to the development segment in us-east-1 and is configured to use the 10.0.0.0 CIDR block. A staging VPC is attached to the staging segment in us-west-1 and is configured to use the 10.5.0.0 CIDR block. The company has updated the route tables for both VPCs with a route that directs any traffic for 0.0.0.0/0 to the core network. The companys network team needs to establish communication between the two VPCs by using the AWS Cloud WAN core network. The network team is not receiving a response during tests of communication between the VPCs. The network team has verified that security groups and network ACLs are not blocking the traffic. What should the network team do to establish this communication?

A : Update both VPC route tables to have a new static route. Configure a route on the development VPC to direct the traffic for 10.0.0.0 to the development VPC attachment. Configure a route on the staging VPC to direct the traffic for 10.5.0.0 to the staging VPC attachment.

B : Update the segment filter to allow traffic on the development and staging segments.

C : Set the isolate-attachments parameter to False for the development and staging segments.

D : Update the core network policy to add a static route for each segment. Configure a route to direct the traffic for 10.0.0.0 to the development VPC attachment. Configure a route to direct the traffic for 10.5.0.0 to the staging VPC attachment.

Answer: D

Question 3

A global delivery company is modernizing its fleet management system. The company has several business units. Each business unit designs and maintains applications that are hosted in its own AWS account in separate application VPCs in the same AWS Region. Each business unit's applications are designed to get data from a central shared services VPC. The company wants the network connectivity architecture to provide granular security controls. The architecture also must be able to scale as more business units consume data from the central shared services VPC in the future. Which solution will meet these requirements in the MOST secure manner?

A : Create a central transit gateway. Create a VPC attachment to each application VPC. Provide full mesh connectivity between all the VPCs by using the transit gateway.

B : Create VPC peering connections between the central shared services VPC and each application VPC in each business unit's AWS account.

C : Create VPC endpoint services powered by AWS PrivateLink in the central shared services VPCreate VPC endpoints in each application VPC.

D : Create a central transit VPC with a VPN appliance from AWS Marketplace. Create a VPN attachment from each VPC to the transit VPC. Provide full mesh connectivity among all the VPCs.

Answer: C

Question 4

A company hosts an application on Amazon EC2 instances behind an Application Load Balancer (ALB). The company recently experienced a network security breach. A network engineer must collect and analyze logs that include the client IP address, target IP address, target port, and user agent of each user that accesses the application. What is the MOST operationally efficient solution that meets these requirements?

A : Configure the ALB to store logs in an Amazon S3 bucket. Download the files from Amazon S3, and use a spreadsheet application to analyze the logs.

B : Configure the ALB to push logs to Amazon Kinesis Data Streams. Use Amazon Kinesis Data Analytics to analyze the logs.

C : Configure Amazon Kinesis Data Streams to stream data from the ALB to Amazon OpenSearch Service (Amazon Elasticsearch Service). Use search operations in Amazon OpenSearch Service (Amazon Elasticsearch Service) to analyze the data.

D : Configure the ALB to store logs in an Amazon S3 bucket. Use Amazon Athena to analyze the logs in Amazon S3.

Answer: D

Question 5

A company has an on-premises data center in the United States. The data center is connected to AWS by an AWS Direct Connect connection. The data center has a private VIF that is connected to a Direct Connect gateway. Recently, the company opened a new data center in Europe and established a new Direct Connect connection between the Europe data center and AWS. A new private VIF connects to the existing Direct Connect gateway. The company wants to use Direct Connect SiteLink to set up a private network between the data center in the United States and the data center in Europe. Which solution will meet these requirements in the MOST operationally efficient manner?

A : Create a new public VIF from each data center. Enable SiteLink on the new public VIFs.

B : Create a new transit VIF from each data center. Enable SiteLink on the new transit VIFs.

C : Use the existing VIF from each data center. Enable SiteLink on the existing private VIFs.

D : Create a new AWS Site-to-Site VPN connection between the data centers. Configure the new connection to use SiteLink.
