Question 16

An ecommerce company needs to Implement additional security controls on all its domain names that are hosted in Amazon Route 53. The company's new policy requires data authentication and data integrity verification for all queries to the company's domain names. The current Route 53 architecture has four public hosted zones.

A network engineer needs to implement DNS Security Extensions (DNSSEC) signing and validation on the hosted zones. The solution must include an alert capability.

Which combination of steps will meet these requirements? {Select THREE.)

Options:

Enable DNSSEC signing for Route 53. Request that Route 53 create a Key-signing key (KSK) based on a customer managed key in AWS Key Management Service (AWS KMS).

Enable DNSSEC signing for Route 53. Request that Route 53 create a zone-signing key (ZSK) based on a customer managed key in AWS Key Management Service (AWS KMS).

Create a chain of trust for the hosted zones by adding a Delegation Signer (DS) record for each subdomain.

Create a chain of trust for the hosted zones by adding a Delegation Signer (DS) record to the parent zone.

Set up an Amazon CloudWatch alarm that provides an alert whenever aDNSSECInternalFailure error or DNSSECKeySigningKeysNeedingAction error is detected.

Set up an AWS CloudTrail alarm that provides an alert whenever a DNSSECInternalFailure error or DNSSECKeySigningKeysNeedingAction error is detected.

Question 17

A company has a highly available application that is hosted in multiple VPCs and in two on-premises data centers. All the VPCs reside in the same AWS Region. All the VPCs require access to each other and to the on-premises data centers for the transfer of files that are multiple gigabytes in size.

A network engineer is designing an AWS Direct Connect solution to connect the on-premises data centers to each VPC.

Which architecture will meet the company's requirements with the LEAST operational overhead?

Options:

Configure a virtual private gateway and a private VIF in each VPC in the Region. Configure a Direct Connect gateway. Associate the VIF of every VPC with the Direct Connect gateway. Create a new private VIF that connects the Direct Connect gateway to each on-premises data center. Configure the new private VIF to exchange BGP routes with the on-premises data centers and to have an MTU of 9001. Use VPC peering between each VPC. Configure stati

Configure a transit gateway in the same Region of each VPC. Attach each VPC to thetransit gateway. Configure a Direct Connect gateway. Associate the Direct Connect gateway with the transit gateway. Associate a new transit VIF with each Direct Connect connection. Configure the new transit VIF to exchange BGP routes and to have an MTU of 9001. Configure route propagation between each VPC and the transit gateway.

Question 18

A company is migrating an existing application to a new AWS account. The company will deploy the application in a single AWS Region by using one VPC and multiple Availability Zones. The application will run on Amazon EC2 instances. Each Availability Zone will have several EC2 instances. The EC2 instances will be deployed in private subnets.

The company's clients will connect to the application by using a web browser with the HTTPS protocol. Inbound connections must be distributed across the Availability Zones and EC2 instances. All connections from the same client session must be connected to the same EC2 instance. The company must provide end-to-end encryption for all connections between the clients and the application by using the application SSL certificate.

Which solution will meet these requirements?

Options:

Create a Network Load Balancer. Create a target group. Set the protocol to TCP and the port to 443 for the target group. Turn on session affinity (sticky sessions). Register the EC2 instances as targets. Create a listener. Set the protocol to TCP and the port to 443 for the listener. Deploy SSL certificates to the EC2 instances.

Create an Application Load Balancer. Create a target group. Set the protocol to HTTP and the port to 80 for the target group. Turn on session affinity (sticky sessions) with an application-basedcookie policy. Register the EC2 instances as targets. Create an HTTPS listener. Set the default action to forward to the target group. Use AWS Certificate Manager (ACM) to create a certificate for the listener.

Create a Network Load Balancer. Create a target group. Set the protocol to TLS and the port to 443 for the target group. Turn on session affinity (sticky sessions). Register the EC2 instances as targets. Create a listener. Set the protocol to TLS and the port to 443 for the listener. Use AWS Certificate Manager (ACM) to create a certificate for the application.

Hey, I tried Cramkey Dumps for my IT certification exam. They are really awesome and helped me pass my exam with wonderful score.

Megan Aug 30, 2024

That’s great!!! I’ll definitely give it a try. Thanks!!!

Melody

My experience with Cramkey was great! I was surprised to see that many of the questions in my exam appeared in the Cramkey dumps.

Colby Aug 17, 2024

Yes, In fact, I got a score of above 85%. And I attribute a lot of my success to Cramkey's dumps.

Josephine

I want to ask about their study material and Customer support? Can anybody guide me?

Zayd Oct 22, 2024

Yes, the dumps or study material provided by them are authentic and up to date. They have a dedicated team to assist students and make sure they have a positive experience.

Alaya

Best Dumps among other dumps providers. I like it so much because of their authenticity.

Kaiden Sep 16, 2024

That's great. I've used other dump providers in the past and they were often outdated or had incorrect information. This time I will try it.

Question 19

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?

Options:

Deploy a Network Load Balancer (NLB) in the production VPC. Create one target group for the EC2 Instances and a second target group for the on-premises servers. Specify IP as the target type. Register the EC2 instances and the on-premises servers with the target groups. Enable connection draining on the NLB.

Deploy an Application Load Balancer (ALB) in the production VPC. Create one target group for the EC2 Instances and a second target group for the on-premises servers. Specify IP as the target type. Register the EC2 instances and the on-premises servers with the target groups. Enable application-based sticky sessions on the ALB.
