ANS-C01 Exam
A company wants to improve visibility into its AWS environment. The AWS environment consists of multiple VPCs that are connected to a transit gateway. The transit gateway connects to an on-premises data center through an AWS Direct Connect gateway and a pair of redundant Direct Connect connections that use transit VIFs. The company must receive notification each time a new route is advertised to AWS from on premises over Direct Connect.
What should a network engineer do to meet these requirements?
A company has an AWS account with four VPCs in the us-east-1 Region. The VPCs consist of a development VPC and three production VPCs that host various workloads.
The company has extended its on-premises data center to AWS with AWS Direct Connect by using a Direct Connect gateway. The company now wants to establish connectivity to its production VPCs and development VPC from on premises. The production VPCs are allowed to route data to each other. However, the development VPC must be isolated from the production VPCs. No data can flow between the development VPC and the production VPCs.
In preparation to implement this solution, a network engineer creates a transit gateway with a single transit gateway route table. Default route table association and default route table propagation are turned off. The network engineer attaches the production VPCs. the development VPC. and the Direct Connect gateway to the transit gateway. For each VPC route table, the network engineer adds a route to 0.0.0.0/0 with the transit gateway as the next destination.
Which combination of steps should the network engineer take next to complete this solution? (Select THREE.)
A company's network engineer is configuring an AWS Site-to-Site VPN connection between a transit gateway and the company's on-premises network. The Site-to-Site VPN connection is configured to use BGP over two tunnels in active/active mode with equal-cost multi-path (ECMP) routing activated on the transit gateway.
When the network engineer attempts to send traffic from the on-premises network to an Amazon EC2 instance, traffic is sent over the first tunnel. However, return traffic is received over the second tunnel and is dropped at the customer gateway. The network engineer must resolve this issue without reducing the overall VPN bandwidth.
