ANS-C01 Exam
A network engineer needs to deploy an AWS Network Firewall firewall into an existing AWS environment. The environment consists of the following:
A transit gateway with all VPCs attached to it
Several hundred application VPCs
A centralized egress internet VPC with a NAT gateway and an internet gateway
A centralized ingress internet VPC that hosts public Application Load Balancers
On-premises connectivity through an AWS Direct Connect gateway attachment
The application VPCs have workloads deployed across multiple Availability Zones in private subnets with the VPC route table s default route (0.0.0.0/0) pointing to the transit gateway. The Network Firewall firewall needs to inspect east-west (VPC-to-VPC) traffic and north-south (internet-bound and on-premises network) traffic by using Suricata compatible rules.
The network engineer must deploy the firewall by using a solution that requires the least possible architectural changes to the existing production environment.
Which combination of steps should the network engineer take to meet these requirements? (Choose three.)
A company is planning to use Amazon S3 to archive financial data. The data is currently stored in an on-premises data center. The company uses AWS Direct Connect with a Direct Connect gateway and a transit gateway to connect to the on-premises data center. The data cannot be transported over the public internet and must be encrypted in transit.
Which solution will meet these requirements?
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.
