ANS-C01 Exam
A company has deployed Amazon EC2 instances in private subnets in a VPC. The EC2 instances must initiate any requests that leave the VPC, including requests to the company's on-premises data center over an AWS Direct Connect connection. No resources outside the VPC can be allowed toopen communications directly to the EC2 instances.
The on-premises data center's customer gateway is configured with a stateful firewall device that filters for incoming and outgoing requests to and from multiple VPCs. In addition, the company wants to use a single IP match rule to allow all the communications from the EC2 instances to its data center from a single IP address.
Which solution will meet these requirements with the LEAST amount of operational overhead?
A European car manufacturer wants to migrate its customer-facing services and its analytics platform from two on-premises data centers to the AWS Cloud. The company has a 50-mile (80.4 km) separation between its on-premises data centers and must maintain that separation between its two locations in the cloud. The company also needs failover capabilities between the two locations in the cloud.
The company's infrastructure team creates several accounts to separate workloads and responsibilities. The company provisions resources in the eu-west-3 Region and in the eu-central-1 Region. The company selects an AWS Direct Connect Partner in each Region and requests two resilient 1 Gbps fiber connections from each provider.
The company's network engineer must establish a connection between all VPCs in the accounts and between the on-premises network and the AWS Cloud. The solution must provide access to all services in both Regions in case of network issues.
Which solution will meet these requirements?
A company is growing rapidly. Data transfers between the company's on-premises systems and Amazon EC2 instances that run in VPCs are limited by the throughput of a single AWS Site-to-Site VPN connection between the company's on-premises data center firewall and an AWS Transit Gateway.
A network engineer must resolve the throttling by designing a solution that is highly available and secure. The solution also must scale the VPN throughput from on premises to the VPC resources to support the increase in traffic.
