Master Amazon ANS-C01 Exam with Reliable Practice Questions

A company is developing an API-based application on AWS for its process workflow requirements. The API will be invoked by clients in the company's on-premises data centers. The company has set up an AWS Direct Connect connection between on premises and AWS. A network engineer decides to implement the API as a private REST API in Amazon API Gateway. The network engineer wants to ensure that clients can reach the API endpoint through private communication.

Which solution can the network engineer use to invoke the API without any additional infrastructure setup?

A company has an internal web-based application that employees use. The company hosts the application over a VPN in the company's on-premises network. The application runs on a fleet of Amazon EC2 instances in a private subnet behind a Network Load Balancer (NLB) in the same subnet. The instances are in an Amazon EC2 Auto Scaling group.

During a recent security incident, SQL injection occurred on the application. A network engineer must implement a solution to prevent SQL injection attacks in the future.

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

A retail company is migrating its on-premises application to the AWS Cloud. Currently, the company has two on-premises data center locations. One data center is on the east coast of the United States, and one data center is on the west coast.

Each data center hosts four database systems. The largest database system stores 500 GB of dat

a. The data centers are interconnected by two 10 GbE circuits for data synchronization. Each data center has two separate 1 GbE upstream internet connections. The company plans to have eight total VPCs to service its multiple business units. Four VPCs will be in the us-east-1 Region, and four will be in the us-west-2 Region.

A network engineer needs to design a connectivity solution that allows VPC-to-VPC connectivity. The solution must also allow secure connections between the on-premises data centers and AWS during the migration process. The company expects spikes in traffic among the VPCs during database synchronization. The company wants to run the migration plan during one weekend and as soon as technically possible. The company also wants to minimize long-term operational and human resources costs.

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

A company has a hybrid IT setup that includes services that run in an on-premises data center and in the AWS Cloud. The company is using AWS Direct Connect to connect its data center to AWS. The company is using one AWS Site-to-Site VPN connection as backup and requires a backup connectivity option to always be present. The company is transitioning to IPv6 by implementing dual-stack architectures.

Which combination of steps will transition the data center's connectivity to AWS in the LEAST amount of time? (Select TWO.)

A network engineer needs to design the architecture for a high performance computing (HPC) workload. Amazon EC2 instances will require 10 Gbps flows and an aggregate throughput of up to 100 Gbps across many instances with low-latency communication.

Which architecture solution will optimize this workload?
