Which of the following solutions would you suggest to address these requirements?
Response:
- A. Generate a separate certificate for each FQDN in each AWS Region using AWS KMS. Associate the certificates with the corresponding ALBs in the relevant AWS Region
- B. Generate a certificate for each FQDN via AWS Certificate Manager. Associate the same FQDN certificate with the ALBs in the relevant AWS Regions
- C. Set up the key pairs and then generate the certificate for each FQDN via AWS KMS. Associate the same FQDN certificate with the ALBs in the relevant AWS Regions
- D. Generate a separate certificate for each FQDN in each AWS Region using AWS Certificate Manager.

NEW QUESTION # 27
An insurance company is planning the migration of workloads from its on-premises data center to the AWS Cloud. The company requires end-to-end domain name resolution. Bi-directional DNS resolution between AWS and the existing on-premises environments must be established. The workloads will be migrated into multiple VPCs. The workloads also have dependencies on each other, and not all the workloads will be migrated at the same time.
Which solution meets these requirements?
- A. Configure a public hosted zone for each application VPC, and create the requisite records. Create a set of Amazon Route 53 Resolver inbound and outbound endpoints in an egress VPC. Define Route 53 Resolver rules to forward requests for the on-premises domains to the on-premises DNS resolver. Associate the application VPC private hosted zones with the egress VPC. and share the Route 53 Resolver rules with the application accounts by using AWS Resource Access Manager. Configure the on-premises DNS servers to forward the cloud domains to the Route 53 inbound endpoints.
- B. Configure a private hosted zone for each application VPC, and create the requisite records. Create a set of Amazon Route 53 Resolver inbound and outbound endpoints in an egress VPC. Define Route 53 Resolver rules to forward requests for the on-premises domains to the on-premises DNS resolver. Associate the application VPC private hosted zones with the egress VPC, and share the Route 53 Resolver rules with the application accounts by using AWS Resource Access Manager. Configure the on-premises DNS servers to forward the cloud domains to the Route 53 inbound endpoints.

Answer: B
Explanation:
Creating a private hosted zone for each application VPC and creating the requisite records would enable end-to-end domain name resolution for the resources. Creating a set of Amazon Route 53 Resolver inbound and outbound endpoints in an egress VPC would enable bi-directional DNS resolution between AWS and the existing on-premises environments. Defining Route 53 Resolver rules to forward requests for the on-premises domains to the on-premises DNS resolver would enable DNS queries from AWS resources to on-premises resources. Associating the application VPC private hosted zones with the egress VPC and sharing the Route 53 Resolver rules with the application accounts by using AWS Resource Access Manager would enable DNS queries among different VPCs and accounts. Configuring the on-premises DNS servers to forward the cloud domains to the Route 53 inbound endpoints would enable DNS queries from on-premises resources to AWS resources1.

NEW QUESTION # 32
A company has an AWS Direct Connect connection between its on-premises data center in the United States (US) and workloads in the us-east-1 Region. The connection uses a transit VIF to connect the data center to a transit gateway in us-east-1.
The company is opening a new office in Europe with a new on-premises data center in England.

NEW QUESTION # 34
A bank built a new version of its banking application in AWS using containers that content to an on- premises database over VPN connection. This application version requires users to also update their client application. The bank plans to deprecate the earlier client version.
However, the company wants to keep supporting earlier clients through their on-premises version of the application to serve a small portion of the customers who haven't yet upgraded.
What design will allow the company to serve both newer and earlier clients in the MOST efficient way?
Response:
- A. Use an Application Load Balancer for the new application. Register both the new and earlier application backends as separate target groups. Use header-based routing to route traffic based on the application version.
- B. Use an Amazon Route 53 multivalue answer routing policy to route older client traffic to the on- premises application version and the rest of the traffic to the new AWS based version.
- C. Use a Classic Load Balancer for the new application. Route all traffic to the new application by using an Elastic Load Balancing (ELB) load balancer DNS. Define a user-agent-based rule on the backend servers to redirect earlier clients to the on-premises application.
- D. Use an Application Load Balancer for the new application. Register both the new and earlier applications as separate target groups and use path-based routing to route traffic based on the application version.

NEW QUESTION # 39
An organization launched an IPv6-only web portal to support IPv6-native mobile clients. Front-end instances launch in an Amazon VPC associated with an appropriate IPv6 CIDR. The VPC IPv4 CIDR is fully utilized. A single subnet exists in each of two Availability Zones with appropriately configured IPv6 CIDR associations. Auto Scaling is properly configured, and no Elastic Load Balancing is used.
Customers say the service is unavailable during peak load times. The network engineer attempts to launch an instance manually and receives the following message: "There are not enough free addresses in subnet 'subnet-12345677' to satisfy the requested number of instances." What action will resolve the availability problem?
- A. Create a new subnet using a VPC secondary IPv4 CIDR, and associate an IPv6 CIDR. Include the new subnet in the Auto Scaling group.
- B. Create a new subnet using a VPC secondary IPv6 CIDR, and associate an IPv6 CIDR. Include the new subnet in the Auto Scaling group.
- C. Add a secondary IPv4 CIDR to the Amazon VPC. Assign secondary IPv4 address space to each of the existing subnets.
- D. Resize the IPv6 CIDR on each of the existing subnets. Modify the Auto Scaling group maximum number of instances.
