Question 20

A software company offers a software-as-a-service (SaaS) accounting application that is hosted in the AWS Cloud The application requires connectivity to the company's on-premises network. The company has two redundant 10 GB AWS Direct Connect connections between AWS and its on-premises network to accommodate the growing demand for the application.

The company already has encryption between its on-premises network and the colocation. The company needs to encrypt traffic between AWS and the edge routers in the colocation within the next few months. The company must maintain its current bandwidth.

What should a network engineer do to meet these requirements with the LEAST operational overhead?

Options:

Deploy a new public VIF with encryption on the existing Direct Connect connections. Reroute traffic through the new public VIF.

Create a virtual private gateway Deploy new AWS Site-to-Site VPN connections from on premises to the virtual private gateway Reroute traffic from the Direct Connect private VIF to the new VPNs.

Deploy a new pair of 10 GB Direct Connect connections with MACsec. Configure MACsec on the edge routers. Reroute traffic to the new Direct Connect connections. Decommission the original Direct Connect connections

Deploy a new pair of 10 GB Direct Connect connections with MACsec. Deploy a new public VIF on the new Direct Connect connections. Deploy two AWS Site-to-Site VPN connections on top of the new public VIF. Reroute traffic from the existing private VIF to the new Site-to-Site connections. Decommission the original Direct Connect connections.

Question 21

A company has a hybrid cloud environment. The company’s data center is connected to the AWS Cloud by an AWS Direct Connect connection. The AWS environment includes VPCs that are connected together in a hub-and-spoke model by a transit gateway. The AWS environment has a transit VIF with a Direct Connect gateway for on-premises connectivity.

The company has a hybrid DNS model. The company has configured Amazon Route 53 Resolver endpoints in the hub VPC to allow bidirectional DNS traffic flow. The company is running a backend application in one of the VPCs.

The company uses a message-oriented architecture and employs Amazon Simple Queue Service (Amazon SQS) to receive messages from other applications over a private network. A network engineer wants to use an interface VPC endpoint for Amazon SQS for this architecture. Client services must be able to access the endpoint service from on premises and from multiple VPCs within the company's AWS infrastructure.

Which combination of steps should the network engineer take to ensure that the client applications can resolve DNS for the interface endpoint? (Choose three.)

Options:

Create the interface endpoint for Amazon SQS with the option for private DNS names turned on.

Create the interface endpoint for Amazon SQS with the option for private DNS names turned off.

Manually create a private hosted zone for sqs.us-east-1.amazonaws.com. Add necessary records that point to the interface endpoint. Associate the private hosted zones with other VPCs.

Use the automatically created private hosted zone for sqs.us-east-1.amazonaws.com with previously created necessary records that point to the interface endpoint. Associate the private hosted zones with other VPCs.

Access the SQS endpoint by using the public DNS name sqs.us-east-1 amazonaws.com in VPCs and on premises.

Access the SQS endpoint by using the private DNS name of the interface endpoint .sqs.us-east-1.vpce.amazonaws.com in VPCs and on premises.

Question 22

A company’s network engineer is designing a hybrid DNS solution for an AWS Cloud workload. Individual teams want to manage their own DNS hostnames for their applications in their development environment. The solution must integrate the application-specific hostnames with the centrally managed DNS hostnames from the on-premises network and must provide bidirectional name resolution. The solution also must minimize management overhead.

Which combination of steps should the network engineer take to meet these requirements? (Choose three.)

Options:

Use an Amazon Route 53 Resolver inbound endpoint.

Modify the DHCP options set by setting a custom DNS server value.

Use an Amazon Route 53 Resolver outbound endpoint.

Create DNS proxy servers.

Create Amazon Route 53 private hosted zones.

Set up a zone transfer between Amazon Route 53 and the on-premises DNS.

I've heard that Cramkey is one of the best websites for exam dumps. They have a high passing rate and the questions are always up-to-date. Is it true?

Cian (not set)

Definitely. The dumps are constantly updated to reflect the latest changes in the certification exams. And I also appreciate how they provide explanations for the answers, so I could understand the reasoning behind each question.

Mylo

Excellent dumps with authentic information… I passed my exam with brilliant score.

Dominik (not set)

That's amazing! I've been looking for good study material that will help me prepare for my upcoming certification exam. Now, I will try it.

Joey

I highly recommend Cramkey Dumps to anyone preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

Dexter (not set)

Agreed. It's definitely worth checking out if you're looking for a comprehensive and reliable study resource.

Victoria

Hey, guess what? I passed the certification exam! I couldn't have done it without Cramkey Dumps.

Isabel (not set)

Same here! I was so surprised when I saw that almost all the questions on the exam were exactly what I found in their study materials.

Question 23

A company uses AWS Direct Connect to connect its corporate network to multiple VPCs in the same AWS account and the same AWS Region. Each VPC uses its own private VIF and its own virtual LAN on the Direct Connect connection. The company has grown and will soon surpass the limit of VPCs and private VIFs for each connection.

What is the MOST scalable way to add VPCs with on-premises connectivity?

Options:

Provision a new Direct Connect connection to handle the additional VPCs. Use the new connection to connect additional VPCs.

Create virtual private gateways for each VPC that is over the service quota. Use AWS Site-to-Site VPN to connect the virtual private gateways to the corporate network.

Create a Direct Connect gateway, and add virtual private gateway associations to the VPCs. Configure a private VIF to connect to the corporate network.

Create a transit gateway, and attach the VPCs. Create a Direct Connect gateway, and associate it with the transit gateway. Create a transit VIF to the Direct Connect gateway.
