List of questions
Question 121

A company has many application VPCs that use AWS Site-to-Site VPN connections for connectivity to an on-premises location. The company's network team wants to gradually migrate to AWS Transit Gateway to provide VPC-to-VPC connectivity.
The network team sets up a transit gateway that uses equal-cost multi-path (ECMP) routing. The network team attaches two temporary VPCs to the transit gateway for testing. The test VPCs contain Amazon EC2 instances to confirm connectivity over the transit gateway between the on-premises location and the VPCs. The network team creates two new Site-to-Site VPN connections to the transit gateway.
During testing, the network team cannot reach the required bandwidth of 2.5 Gbps over the pair of new Site-to-Site VPN connections.
Which combination of steps should the network team take to improve bandwidth performance and minimize network congestion? (Select THREE)
Question 122

A company is building a new workload on AWS that uses an Application Load Balancer (ALB) The company has configured a new ALB target group that uses slow start mode. A team begins registering Amazon EC2 Instances as targets in the new target group. During testing, the team observes that the targets did not enter slow start mode.
What caused the targets to not enter slow start mode?
Question 123

A company is using third-party firewall appliances to monitor and inspect traffic on premises The company wants to use this same model on AWS. The company has a single VPC with an internet gateway. The VPC has a fleet of web servers that run on Amazon EC2 instances that are managed by an Auto Scaling group.
The company's network team needs to work with the security team to establish inline inspection of all packets that are sent to and from the web servers. The solution must scale as the fleet of virtual firewall appliances scales.
Which combination of steps should the network team take to implement this solution? (Select THREE)
Question 124

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?
Question 125

A company has business operations in the United States and in Europe. The company's public applications are running on AWS and use three transit gateways. The transit gateways are located in the us-west-2. us-east-1. and eu-central-1 Regions. All the transit gateways are connected to each other in a full mesh configuration.
The company accidentally removes the route to the eu-central-1 VPCs from the us-west-2 transit gateway route table. The company also accidentally removes the route to the us-west-2 VPCs from the eu-central-1 transit gateway route table.
How can a network engineer identify the misconfiguration with the LEAST operational overhead?
Question 126

Two companies are merging. The companies have a large AWS presence with multiple VPCs and are designing connectivity between their AWS networks. Both companies are using AWS Direct Connect with a Direct Connect gateway. Each company also has a transit gateway and multiple AWS Site-to-Site VPN connections from its transit gateway to on-premises resources. The new solution must optimize network visibility, throughput, logging, and monitoring.
Which solution will meet these requirements?
Question 127

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?
Question 128

A company has developed a new web application on AWS. The application runs on Amazon Elastic Container Service (Amazon ECS) on AWS Fargate behind an Application Load Balancer (ALB) in the us-east-1 Region. The application uses Amazon Route 53 to host the DNS records for the domain. The content that is served from the website is mostly static images and files that are not updated frequently. Most of the traffic to the website from end users will originate from the United States. Some traffic will originate from Canada and Europe.
A network engineer needs to design a solution that will reduce latency for end users at the lowest cost. The solution also must ensure that all traffic is encrypted in transit until the traffic reaches the ALB.
Which solution will meet these requirements?
Question 129

A financial company offers investment forecasts and recommendations to authorized users through the internet. All the services are hosted in the AWS Cloud. A new compliance requirement states that all the internet service traffic from any host must be logged and retained for 2 years. In its development AWS accounts, the company has designed, tested, and verified a solution that uses Amazon VPC Traffic Mirroring with a Network Load Balancer (NLB) as the traffic mirror target. While the solution runs in one AWS account, the solution mirrors the traffic to another AWS account.
A network engineer notices that not all traffic is mirrored when the solution is deployed into the production environment. The network engineer also notices that this behavior is random.
Which statements are possible explanations for why not all the traffic is mirrored? (Select TWO.)
Question 130

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?
