NEW QUESTION # 105
A company installed an AWS Site-to-Site VPN and configured it to use two tunnels. The company has learned that the VPN connectivity is unstable. During a ping test from the on-premises data center to AWS,a network engineer notices that the first few ICMP replies time out but that subsequent requests are successful.
The AWS Management Console shows that the status for both tunnels last changed at the same time the ping responses were successfully received. Which steps should the network engineer take to resolve the instability?
(Choose two.)
Response:
- A. Use AS PATH prepending on one path to cause all traffic to prefer that tunnel
- B. Use a higher multi-exit discriminator (MED) value on the preferred path to prefer that tunnel
- C. Enable dead peer detection (DPD) on the customer gateway device
- D. Change the tunnel configuration to active/standby on the virtual private gateway
- E. Send ICMP requests to an instance in the VPC every 5 seconds from the on-premises network
Answer: A,B

NEW QUESTION # 110
A company recently migrated its Amazon EC2 instances to VPC private subnets to satisfy a security compliance requirement. The EC2 instances now use a NAT gateway for internet access. After the migration, some long-running database queries from private EC2 instances to a publicly accessible third-party database no longer receive responses. The database query logs reveal that the queries successfully completed after 7 minutes but that the client EC2 instances never received the response. Which configuration change should a network engineer implement to resolve this issue?
- A. Close idle TCP connections through the NAT gateway.
- B. Configure the NAT gateway timeout to allow connections for up to 600 seconds.
- C. Enable TCP keepalive on the client EC2 instances with a value of less than 300 seconds.
- D. Enable enhanced networking on the client EC2 instances.
Answer: C
Explanation:
When a TCP connection is idle for a long time, it may be terminated by network devices, including the NAT gateway. By enabling TCP keepalive, the client EC2 instances can periodically send packets to the third-party database to indicate that the connection is still active, preventing it from being terminated prematurely.

NEW QUESTION # 113
You currently use a single security group assigned to all nodes in a clustered NoSQL database. Only your cluster members in one region must be able to connect to each other.
This security group uses a self-referencing rule using the cluster security group's group-id to make it easier to add or remove nodes from the cluster.
You need to make this database comply with out-of-region disaster recovery requirements and ensure that the network traffic between the nodes is encrypted when travelling between regions.
How should you enable secure cluster communication while deploying additional cluster members in another AWS region?
Response:
- A. Use public IP addresses and TLS to securely communicate between cluster nodes in each AWS region, and create cluster security group rules that reference each other's security group-id in each region.
- B. Create an IPsec VPN between AWS regions, use private IP addresses to route traffic, and create cluster security group CIDR-based rules that correspond with the VPC CIDR in the other region.
- C. Use public IP addresses and TLS to securely communicate between cluster nodes in each AWS region, and create cluster security group CIDR-based rules that correspond with the VPC CIDR in the other region.
- D. Create an IPsec VPN between AWS regions, use private IP addresses to route traffic, and create cluster security group rules that reference each other's security group-id in each region.
Answer: B

NEW QUESTION # 115
A company has hundreds of Amazon EC2 instances that are running in two production VPCs across all Availability Zones in the us-east-1 Region. The production VPCs are named VPC A and VPC B.
A new security regulation requires all traffic between production VPCs to be inspected before the traffic is routed to its final destination. The company deploys a new shared VPC that contains a stateful firewall appliance and a transit gateway with a VPC attachment across all VPCs to route traffic between VPC A and VPC B through the firewall appliance for inspection. During testing, the company notices that the transit gateway is dropping the traffic whenever the traffic is between two Availability Zones.
What should a network engineer do to fix this issue with the LEAST management overhead?
- A. In the shared VPC, configure one VPC peering connection to VPC A and another VPC peering connection to VPC B.
- B. Enable transit gateway appliance mode on the VPC attachment in VPC A and VPC B.
- C. In the shared VPC, replace the VPC attachment with a VPN attachment. Create a VPN tunnel between the transit gateway and the firewall appliance. Configure BGP.

NEW QUESTION # 119
A global company operates all its non-production environments out of three AWS Regions: eu- west-1, us-east-1, and us-west-1. The company hosts all its production workloads in two on- premises data centers. The company has 60 AWS accounts and each account has two VPCs in each Region. Each VPC has a virtual private gateway where two VPN connections terminate for resilient connectivity to the data centers. The company has 360 VPN tunnels to each data center, resulting in high management overhead. The total VPN throughput for each Region is 500 Mbps.
The company wants to migrate the production environments to AWS. The company needs a solution that will simplify the network architecture and allow for future growth. The production environments will generate an additional 2 Gbps of traffic per Region back to the data centers.
This traffic will increase over time.
Which solution will meet these requirements?
- A. Set up an AWS Direct Connect connection from each data center to AWS in each Region. Create and attach private VIFs to a single Direct Connect gateway. Attach the Direct Connect gateway to all the VPCs. Remove the existing VPN connections that are attached directly to the virtual private gateways.
- B. Peer all the VPCs in each Region to a new VPC in each Region that will function as a centralized transit VPC. Create new VPN connections from each data center to the transit VPCs. Terminate the original VPN connections that are attached to all the original VPCs. Retain the new VPN connection to the new transit VPC in each Region.
- C. Create a single transit gateway with VPN connections from each data center. Share the transit gateway with each account by using AWS Resource Access Manager (AWS RAM). Attach the transit gateway to each VPC. Remove the existing VPN connections that are attached directly to the virtual private gateways.
- D. Create a transit gateway in each Region with multiple newly commissioned VPN connections from each data center. Share the transit gateways with each account by using AWS Resource Access Manager (AWS RAM). In each Region, attach the transit gateway to each VPRemove the existing VPN connections that are attached directly to the virtual private gateways.
Answer: D
Explanation:
An AWS Transit Gateway provides the option of creating an IPsec VPN connection between your remote network and the Transit Gateway over the internet. A Transit Gateway is a regional resource.
https://docs.aws.amazon.com/whitepapers/latest/aws-vpc-connectivity-options/aws-transit- gateway-vpn.html You can use AWS Resource Access Manager (RAM) to share a transit gateway for VPC attachments across accounts or across your organization in AWS Organizations. That helps reducing the VPN connections.
https://docs.aws.amazon.com/vpc/latest/tgw/transit-gateway-share.html
AWS Transit Gateway can scale up to 50 Gbps throughput aggregating multiple VPN tunnels.
