QUESTION DESCRIPTION:
A company is deploying a new application in the AWS Cloud. The company wants a highly available web server that will sit behind an Elastic Load Balancer. The load balancer will route requests to multiple target groups based on the URL in the request. All traffic must use HTTPS. TLS processing must be offloaded to the load balancer. The web server must know the user’s IP address so that the company can keep accurate logs for security purposes.
Which solution will meet these requirements?
Correct Answer & Rationale:
Answer: A
Explanation:
An Application Load Balancer (ALB) can be used to route traffic to multiple target groups based on the URL in the request. The ALB can be configured with an HTTPS listener to ensure all traffic uses HTTPS. TLS processing can be offloaded to the ALB, which reduces the load on the web server. Path-based routing rules can be used to route traffic to the correct target group based on the URL in the request. The X-Forwarded-For request header can be included with traffic to the targets, which will allow the web server to know the user's IP address and keep accurate logs for security purposes.
QUESTION DESCRIPTION:
A company has two AWS accounts one for Production and one for Connectivity. A network engineer needs to connect the Production account VPC to a transit gateway in the Connectivity account. The feature to auto accept shared attachments is not enabled on the transit gateway.
Which set of steps should the network engineer follow in each AWS account to meet these requirements?
Correct Answer & Rationale:
Answer: A
Explanation:
step 1: In the Production account, create a resource share in AWS Resource Access Manager for the transit gateway and provide the Connectivity account ID. Enabling the feature to allow external accounts is also required to share resources between accounts. Step 2: In the Connectivity account, accept the shared resource. This action will allow the Production account to use the transit gateway in the Connectivity account. Step 3: In the Connectivity account, create an attachment to the VPC subnets. This attachment will enable communication between the VPC in the Production account and the transit gateway in the Connectivity account. Step 4: In the Production account, accept the attachment and associate a route table with the attachment. This will enable the VPC to route traffic through the transit gateway to other resources in the Connectivity account.
QUESTION DESCRIPTION:
A company has an application VPC and a networking VPC that are connected through VPC peering. The networking VPC contains a Network Load Balancer (NLB). The application VPC contains Amazon EC2 instances that run an application. The EC2 instances are part of a target group that is associated with the NLB in the networking VPC.
The company configures a third VPC and peers it to the networking VPC. The new VPC contains a new version of the existing application. The new version of the application runs on new EC2 instances in an application subnet. The new version of the application runs in a different Availability Zone than that original version of the application.
The company needs to establish connectivity between the NLB and the new version of the application.
Which combination of steps will meet this requirement? (Choose three.)
Correct Answer & Rationale:
Answer: B, C, F
Explanation:
Since the new application EC2 instances reside in a different VPC, the NLB must use IP addresses to register the instances. Instance IDs can only be used for targets within the same VPC as the NLB.
To handle traffic efficiently, the NLB must be configured in the Availability Zone where the new application EC2 instances are running. This ensures proper routing and load balancing for instances in that zone.
The network ACL for the new application's subnet must allow both inbound and outbound traffic to facilitate communication between the NLB in the networking VPC and the application EC2 instances in the new VPC.
QUESTION DESCRIPTION:
An Australian ecommerce company hosts all of its services in the AWS Cloud and wants to expand its customer base to the United States (US). The company is targeting the western US for the expansion.
The company’s existing AWS architecture consists of four AWS accounts with multiple VPCs deployed in the ap-southeast-2 Region. All VPCs are attached to a transit gateway in ap-southeast-2. There are dedicated VPCs for each application service. The company also has VPCs for centralized security features such as proxies, firewalls, and logging.
The company plans to duplicate the infrastructure from ap-southeast-2 to the us-west-1 Region. A network engineer must establish connectivity between the various applications in the two Regions. The solution must maximize bandwidth, minimize latency and minimize operational overhead.
Which solution will meet these requirements?
Correct Answer & Rationale:
Answer: B
Explanation:
Peering the transit gateways in each region would establish a private network connection between the two regions, allowing the company to route traffic between the VPCs in different regions without going over the public internet. This would help minimize latency and maximize bandwidth while reducing the operational overhead of managing multiple VPN connections.
QUESTION DESCRIPTION:
A company has an AWS Site-to-Site VPN connection between its existing VPC and on-premises network. The default DHCP options set is associated with the VPC. The company has an application that is running on an Amazon Linux 2 Amazon EC2 instance in the VPC. The application must retrieve an Amazon RDS database secret that is stored in AWS Secrets Manager through a private VPC endpoint. An on-premises application provides internal RESTful API service that can be reached by URL (https://api.example.internal). Two on-premises Windows DNS servers provide internal DNS resolution.
The application on the EC2 instance needs to call the internal API service that is deployed in the on-premises environment. When the application on the EC2 instance attempts to call the internal API service by referring to the hostname that is assigned to the service, the call fails. When a network engineer tests the API service call from the same EC2 instance by using the API service's IP address, the call is successful.
What should the network engineer do to resolve this issue and prevent the same problem from affecting other resources in the VPC?
Correct Answer & Rationale:
Answer: B
Explanation:
Creating an Amazon Route 53 Resolver rule and associating it with the VPC would enable forwarding of DNS queries for a specified domain name (example.internal) to a specified IP address (the on-premises Windows DNS servers) 3 . This would allow EC2 instances in the VPC to resolve the internal API service by using its hostname. Configuring the rule to forward DNS queries only if the domain name matches example.internal would also allow EC2 instances to use the Amazon Route 53 Resolver server for other DNS queries, such as those for AWS services through private VPC endpoints 2 .
QUESTION DESCRIPTION:
A company has 10 Amazon EC2 instances that run web server software in a production VPC. The company also has 10 web servers that run in an on-premises data center. The company has a 10 Gbps AWS Direct Connect connection between the on-premises data center and the production VPC. The data center uses the 10.100.0.0/20 CIDR block.
The company needs to implement a load balancing solution that receives HTTPS traffic from thousands of external users. The solution must distribute the traffic across the web servers on AWS and the web servers in the data center. Regardless of the location of the web servers, HTTPS requests must go to the same web server for the duration of the session.
Which solution will meet these requirements?
Correct Answer & Rationale:
Answer: B
Explanation:
Application Load Balancer (ALB) is the best choice for handling HTTPS traffic because it operates at the application layer (Layer 7). It supports features such as sticky sessions, which are required to ensure that requests from the same user are routed to the same server for the duration of the session.
IP as the Target Type : To load balance traffic between both EC2 instances and on-premises servers, the target type must be set to IP. This configuration allows the ALB to distribute traffic to servers identified by IP addresses, including those in the on-premises data center.
Sticky Sessions : Application-based sticky sessions ensure that the load balancer uses cookies to route requests consistently to the same web server, meeting the requirement for session persistence.
QUESTION DESCRIPTION:
A company manages resources across VPCs in multiple AWS Regions. The company needs to connect to the resources by using its internal domain name. A network engineer needs to apply the aws.example.com DNS suffix to all resources.
What must the network engineer do to meet this requirement?
Correct Answer & Rationale:
Answer: D
Explanation:
Creating one private hosted zone for aws.example.com and associating it with every VPC that has resources would enable DNS resolution for all resources by using their internal domain name. Creating an alias record in each private hosted zone with the full AWS service endpoint pointing to the interface VPC endpoint in the shared services VPC would enable private connectivity to Amazon S3 and AWS Systems Manager without using public endpoints.
QUESTION DESCRIPTION:
A company has workloads that run in a VPC. The workloads access Amazon S3 by using an S3 gateway endpoint. The company also has on-premises workloads that need to access Amazon
S3 privately over a VPN connection. The company has established the VPN connection to the VPC.
Which solution will provide connectivity to Amazon S3 from the VPC workloads and the on-premises workloads in the MOST operationally efficient way?
Correct Answer & Rationale:
Answer: C
Explanation:
The correct solution is to use an S3 interface endpoint and an on-premises DNS resolver. An S3 interface endpoint allows you to access Amazon S3 using private IP addresses within your VPC. An on-premises DNS resolver can be configured to forward the DNS queries for the S3 domain names to the S3 interface endpoint, so that the on-premises workloads can access Amazon S3 privately over the VPN connection. This solution is operationally efficient, as it does not require any additional infrastructure or changes to the existing workloads. The VPC workloads can continue to use the S3 gateway endpoint, which provides lower latency and higher throughput than the S3 interface endpoint.
QUESTION DESCRIPTION:
A company has established connectivity between its on-premises data center in Paris, France, and the AWS Cloud by using an AWS Direct Connect connection. The company uses a transit VIF that connects the Direct Connect connection with a transit gateway that is hosted in the Europe (Paris) Region. The company hosts workloads in private subnets in several VPCs that are attached to the transit gateway.
The company recently acquired another corporation that hosts workloads on premises in an office building in Tokyo, Japan. The company needs to migrate the workloads from the Tokyo office to AWS. These workloads must have access to the company's existing workloads in Paris. The company also must establish connectivity between the Tokyo office building and the Paris data center.
In the Asia Pacific (Tokyo) Region, the company creates a new VPC with private subnets for migration of the workloads. The workload migration must be completed in 5 days. The workloads cannot be directly accessible from the internet.
Which set of steps should a network engineer take to meet these requirements?
Correct Answer & Rationale:
Answer: C
Explanation:
Option C is the best solution because it allows the company to use transit gateways to connect the VPCs in different regions and the on-premises sites. Transit gateways support inter-region peering and VPN attachments, which enable secure and scalable connectivity. Option A is not valid because public subnets are not suitable for workloads that cannot be directly accessible from the internet. Option B is not valid because Direct Connect connections take longer than 5 days to provision.
