Question 1

A network engineer needs to build an encrypted connection between an on-premises data center and a VPC. The network engineer attaches the VPC to a virtual private gateway and sets up an AWS Site-to-Site VPN connection. The VPN tunnel is UP after configuration and is working. However, during rekey for phase 2 of the VPN negotiation, the customer gateway device is receiving different parameters than the parameters that the device is configured to support. The network engineer checks the IPsec configuration of the VPN tunnel. The network engineer notices that the customer gateway device is configured with the most secure encryption algorithms that the AWS Site-to-Site VPN configuration file provides. What should the network engineer do to troubleshoot and correct the issue?

A : Check the native virtual private gateway logs. Restrict the VPN tunnel options to the specific VPN parameters that the virtual private gateway requires.

B : Check the native customer gateway logs. Restrict the VPN tunnel options to the specific VPN parameters that the customer gateway requires.

C : Check Amazon CloudWatch logs of the virtual private gateway. Restrict the VPN tunnel options to the specific VPN parameters that the virtual private gateway requires.

D : Check Amazon CloudWatch logs of the customer gateway. Restrict the VPN tunnel options to the specific VPN parameters that the customer gateway requires.

Answer: B

Question 2

A company has configured an AWS Cloud WAN core network with edge locations in the us-east-1 Region and the us-west-1 Region. Each edge location has two segments: development and staging. The segments use the default core network policy. The company has attached VPCs to the core network. A development VPC is attached to the development segment in us-east-1 and is configured to use the 10.0.0.0 CIDR block. A staging VPC is attached to the staging segment in us-west-1 and is configured to use the 10.5.0.0 CIDR block. The company has updated the route tables for both VPCs with a route that directs any traffic for 0.0.0.0/0 to the core network. The companys network team needs to establish communication between the two VPCs by using the AWS Cloud WAN core network. The network team is not receiving a response during tests of communication between the VPCs. The network team has verified that security groups and network ACLs are not blocking the traffic. What should the network team do to establish this communication?

A : Update both VPC route tables to have a new static route. Configure a route on the development VPC to direct the traffic for 10.0.0.0 to the development VPC attachment. Configure a route on the staging VPC to direct the traffic for 10.5.0.0 to the staging VPC attachment.

B : Update the segment filter to allow traffic on the development and staging segments.

C : Set the isolate-attachments parameter to False for the development and staging segments.

D : Update the core network policy to add a static route for each segment. Configure a route to direct the traffic for 10.0.0.0 to the development VPC attachment. Configure a route to direct the traffic for 10.5.0.0 to the staging VPC attachment.

Answer: D

Question 3

A gaming company is running an online multiplayer game in multiple AWS Regions The company needs traffic from its end users to be routed to the Region that is closest to the end users geographically When maintenance occurs in a Region, traffic must be routed to the next closest Region with no changes to the IP addresses being used as connections by the end users

Which solution will meet these requirements?

A : eate an Amazon CloudFront distribution in front of all the Regions

B : an Amazon Route 53 geoproximity routing policy to navigate traffic to the closest Region

C : an Amazon Route 53 geolocation routing policy to navigate traffic to the closest Region

D : nfigure AWS Global Accelerator in front of all the Regions

Answer: D

Question 4

A company wants to implement a distributed architecture on AWS that uses a Gateway Load Balancer (GWLB) and GWLB endpoints. The company has chosen a hub-and-spoke model. The model includes a GWLB and virtual appliances that are deployed into a centralized appliance VPC and GWLB endpoints. The model also includes internet gateways that are configured in spoke VPCs. Which sequence of traffic flow to the internet from the spoke VPC is correct?

A : 1.An application in a spoke VPC sends traffic to the GWLB endpoint based on the VPC route table configuration.2. Traffic is delivered securely and privately to the GWLB.3. The GWLB sends the traffic to a virtual appliance for inspection.4. Return traffic flows back to the GWLB endpoint and out to the internet through the internet gateway.

B : 1. An application in a spoke VPC sends traffic to the GWLB endpoint based on the VPC route table configuration.2. Traffic is delivered securely and privately to the GWLB endpoint.3. The GWLB sets the X-Forwarded-For request header and sends the traffic to a virtual appliance for inspection.4. Return traffic flows back to the GWLB and out to the internet through an internet gateway.

C : 1. An application in a spoke VPC sends traffic to the GWLB endpoint.2. Traffic is delivered securely and privately to the GWLB.3. The GWLB sets the X-Forwarded-For request header and sends the traffic to a virtual appliance for inspection.4. Return traffic flows back to the GWLB endpoint and out to the internet through the internet gateway.

D : 1. An application in a spoke VPC sends traffic to the GWLB.2. Traffic is delivered securely and privately to the GWLB endpoint.3. The GWLB sends the traffic to a virtual appliance for inspection.4. Return traffic flows back to the GWLB and out to the internet through an internet gateway.

Answer: A

Question 5

A consulting company manages AWS accounts for its customers. One of the company's customers needs to add intrusion prevention for its environment without having to re-architect the environment. The customer's environment includes five VPCs in two AWS Regions in the United States. VPC-to-VPC connectivity is achieved through VPC peering. The customer does not plan to increase the number of VPCs within the next 2 years. The solution must accommodate unencrypted traffic. Which solution will meet these requirements?

A : Configure VPC security groups and network ACLs.

B : Use an AWS Network Firewall centralized deployment model in each VPC.

C : Use an AWS Network Firewall distributed deployment model in each VPC.

D : Deploy AWS Shield in each VPC.

Answer: C
