Amazon ANS-C00 Practice Test - Questions Answers, Page 13

Within the TCP/IP model what is the name of the Packet Data Unit (PDU) used between Transport Layers for communication between sender and receiver

A company uses multiple AWS accounts within AWS Organizations and has services deployed in a single AWS Region. The instances in a private subnet occasionally download patches from the internet through a NAT gateway. The company recently migrated from VPC peering to AWS Transit Gateway. The cumulative traffic through deployed NAT gateways is less than 1 Gbps. The NAT gateway hourly charge contributes to most of the NAT gateway costs across all inked accounts.

What should the company do to reduce NAT gateway hourly costs?

A company has an application running in an Amazon VPC that must be able to communicate with on-premises resources in a data center. Network traffic between AWS and the data center will initially be minimal, but will increase to more than 10 Gbps over the next few months. The company's goal is to launch the application as quickly as possible.

The network engineer has been asked to design a hybrid IT connectivity solution. What should be done to meet these requirements?

Your company has a highly available Direct Connect solution that utilizes two datacenters. Each data center contains one two-connection LAG and one standard DX connection. How many LOAs will be filled out in total if your company completes an order to add a new connection to each one of the LAGs?

You are designing the network infrastructure for an application server in Amazon VPC. Users will access all the application instances from the Internet and from an on-premises network. The on-premises network is connected to your VPC over an AWS Direct Connect link.

How should you design routing to meet these requirements?

You have a global corporate network with 153 individual IP prefixes in your internal routing table. You establish a private virtual interface over AWS Direct Connect to a VPC that has an Internet gateway (IGW). All instances in the VPC must be able to route to the Internet via an IGW and route to the global corporate network via the VGW. How should you configure your on-premises BGP peer to meet these requirements?

Your company maintains an Amazon Route 53 private hosted zone. DNS resolution is restricted to a single, pre-existing VPC. For a new application deployment, you create an additional VPC in the same AWS account. Both this new VPC and your on-premises DNS infrastructure must resolve records in the existing private hosted zone. Which two activities are required to enable DNS resolution both within the new VPC and from the on-premises infrastructure? (Choose two.)

You deploy your Internet-facing application is the us-west-2(Oregon) region. To manage this application and upload content from your corporate network, you have a 1-Gbps AWS Direct Connect connection with a private virtual interface via one of the associated Direct Connect locations. In normal operation, you use approximately 300 Mbps of the available bandwidth, which is more than your Internet connection from the corporate network.

You need to deploy another identical instance of the application is us-east-1(N Virginia) as soon as possible. You need to use the benefits of Direct Connect. Your design must be the most effective solution regarding cost, performance, and time to deploy.

Which design should you choose?

You have just configured an Elastic Load Balancer. Assuming all settings are configured properly, about how long will it take an instance to become healthy with a 6 second HealthCheck Interval, an unhealthy threshold of 5 and a healthy threshold of 10?
