Some new questions:
Q
A company has a 2 Gbps AWS Direct Connect hosted connection from the company’s office to a VPC in the ap-southeast-2 Region. A network engineer adds a 5 Gbps Direct Connect hosted connection from a different Direct Connect location in the same Region. The hosted connections are connected to different routers from the office with an iBGP session running in between the routers.
The network engineer wants to ensure that the VPC uses the 5 Gbps hosted connection to route traffic to the office. Failover to the 2 Gbps hosted connection must occur when the 5 Gbps hosted connection is down.
Which solution will meet these requirements?
A. Configure an outbound BGP policy from the router that is connected to the 2 Gbps connection. Advertise routes with a longer AS_PATH attribute to AWS.
B. Advertise a longer prefix route from the router that is connected to the 2 Gbps connection.
C. Advertise a less specific route from the router that is connected to the 5 Gbps connection.
D. Configure an outbound BGP policy from the router that is connected to the 5 Gbps connection. Advertise routes with a longer AS_PATH attribute to AWS.

Q
A company has a VPC in the AWS Cloud. The company recently acquired a competitor that also has a VPC in the AWS Cloud. A network engineer discovers an IP address overlap between the two VPCs. Both VPCs require access to an AWS Marketplace partner service.
Which solution will ensure interoperability among the VPC hosted services and the AWS Marketplace partner service?
A. Configure VPC peering with static routing between the VPCs. Configure an AWS Site-to-Site VPN connection with static routing to the partner service.
B. Configure a NAT gateway in the VPCs. Configure default routes in each VPC to point to the local NAT gateway. Attach each NAT gateway to a transit gateway. Configure an AWS Site-to-Site VPN connection with static routing to the partner service.
C. Configure AWS PrivateLink to facilitate connectivity between the VPCs and the partner service. Use the DNS name that is created with the associated interface endpoints to route traffic between the VPCs and the partner service.
D. Configure a NAT instance in the VPCs. Configure default routes in each VPC to point to the local NAT instance. Configure an interface endpoint in each VPC to connect to the partner service. Use the DNS name that is created with the associated interface endpoints to route traffic between the VPCs and the partner service.

Q
A company uses Amazon Route 53 to host a public hosted zone for example.com. A network engineer recently reduced the TTL on several records to 60 seconds. The network engineer wants to assess whether the change has increased the number of queries to Route 53 beyond the expected levels that the company identified before the change. The network engineer must obtain the number of queries that have been made to the example.com public hosted zone.
Which solution will provide this information?
A. Create a new trail in AWS CloudTrail to include Route 53 data events. Send logs to Amazon CloudWatch Logs. Set up a CloudWatch metric filter to count the number of queries and create graphs.
B. Use Amazon CloudWatch to access the AWS/Route 53 namespace and to check the DNSQuenes metric tor the public hosted zone.
C. Use Amazon CloudWatch to access the AWS/Route 53 Resolver namespace and to check the InboundQueryVolume metric for a specific endpoint.
D. Configure logging to Amazon CloudWatch for the public hosted zone. Set up a CloudWatch metric filter to count the number of queries and create graphs.

Q
A company uses the us-east-1 Region and the ap-south-1 Region for its business units (BUs). The BUs are named BU-1 and BU-2. For each BU. there are two VPCs in us-east-1 and one VPC in ap-south-1.
Because of workload isolation requirements, resources can communicate within the same BU but cannot communicate with resources in the other BU. The company plans to add more BUs and plans to expand into more Regions.
Which solution will meet these requirements with the MOST operational efficiency?
A. Configure an AWS Cloud WAN network that operates in the required Regions Attach all BU VPCs to the AWS Cloud WAN core network. Update the AWS Cloud WAN segment actions to configure new routes to deny traffic between the different BU segments.
B. Configure a transit gateway in each Region. Configure peering between the transit gateways. Attach the BU VPCs to the transit gateway in the corresponding Region. Configure the transit gateway and VPC route tables to isolate traffic between BU VPCs.
C. Configure an AWS Cloud WAN network that operates in the required Regions. Attach all BU VPCs to the AWS Cloud WAN core network. Update the core network policy by setting the isolate-attachments parameter for each segment.
D. Configure an AWS Cloud WAN network that operates in the required Regions. Create AWS Cloud WAN segments for each BU. Configure VPC attachments for each BU’s VPCs to the corresponding BU segment.
