Question 1

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 2

A company has an on-premises data center in the United States. The data center is connected to AWS by an AWS Direct Connect connection. The data center has a private VIF that is connected to a Direct Connect gateway. Recently, the company opened a new data center in Europe and established a new Direct Connect connection between the Europe data center and AWS. A new private VIF connects to the existing Direct Connect gateway. The company wants to use Direct Connect SiteLink to set up a private network between the data center in the United States and the data center in Europe. Which solution will meet these requirements in the MOST operationally efficient manner?

A : Create a new public VIF from each data center. Enable SiteLink on the new public VIFs.

B : Create a new transit VIF from each data center. Enable SiteLink on the new transit VIFs.

C : Use the existing VIF from each data center. Enable SiteLink on the existing private VIFs.

D : Create a new AWS Site-to-Site VPN connection between the data centers. Configure the new connection to use SiteLink.

Answer: C

Question 3

An IoT company sells hardware sensor modules that periodically send out temperature, humidity, pressure, and location data through the MQTT messaging protocol. The hardware sensor modules send this data to the company's on-premises MQTT brokers that run on Linux servers behind a load balancer. The hardware sensor modules have been hardcoded with public IP addresses to reach the brokers. The company is growing and is acquiring customers across the world. The existing solution can no longer scale and is introducing additional latency because of the company's global presence. As a result, the company decides to migrate its entire infrastructure from on premises to the AWS Cloud. The company needs to migrate without reconfiguring the hardware sensor modules that are already deployed across the world. The solution also must minimize latency. The company migrates the MQTT brokers to run on Amazon EC2 instances. What should the company do next to meet these requirements?

A : ace the EC2 instances behind a Network Load Balancer (NLB). Configure TCP listeners. Use Bring Your Own IP (BYOIP) from the on-premises network with the NLB.

B : ace the EC2 instances behind a Network Load Balancer (NLB). Configure TCP listeners. Create an AWS Global Accelerator accelerator in front of the NLUse Bring Your Own IP (BYOIP) from the on-premises network with Global Accelerator.

C : ace the EC2 instances behind an Application Load Balancer (ALB). Configure TCP listeners. Create an AWS Global Accelerator accelerator in front of the ALB. Use Bring Your Own IP (BYOIP) from the on-premises network with Global Accelerator

D : ace the EC2 instances behind an Amazon CloudFront distribution. Use Bring Your Own IP (BYOIP) from the on-premises network with CloudFront.

Answer: B

Question 4

A company has set up hybrid connectivity between its VPCs and its on-premises data center. The company has the on-premises.example.com subdomain configured at its DNS server in the onpremises data center. The company is using the aws.example.com subdomain for workloads that run on AWS across different VPCs and accounts. Resources in both environments can access each other by using IP addresses. The company wants workloads in the VPCs to be able to access resources on premises by using the on-premises.example.com DNS names. Which solution will meet these requirements with MINIMUM management of resources?

A : Create an Amazon Route 53 Resolver outbound endpoint. Configure a Resolver rule that conditionally forwards DNS queries for on-premises.example.com to the on-premises DNS server. Associate the rule with the VPCs.

B : Create an Amazon Route 53 Resolver inbound endpoint and a Resolver outbound endpoint. Configure a Resolver rule that conditionally forwards DNS queries for on-premises.example.com to the on-premises DNS server. Associate the rule with the VPCs.

C : Launch an Amazon EC2 instance. Install and configure BIND software to conditionally forward DNS queries for on-premises.example.com to the on-premises DNS server. Configure the EC2 instance's IP address as a custom DNS server in each VPC.

D : Launch an Amazon EC2 instance in each VPC. Install and configure BIND software to conditionally forward DNS queries for on-premises.example.com to the on-premises DNS server. Configure the EC2 instance's IP address as a custom DNS server in each VPC.

Answer: A

Question 5

A company deployed an application in two AWS Regions in one AWS account. The company has one VPC in each Region. The VPCs use non-overlapping private CIDR ranges. The company needs to connect both VPCs to a single on-premises data center to test the application. The application requires up to 800 Mbps of throughput. A network engineer needs to establish connectivity between the VPCs and the on-premises data center. Which solution will meet this requirement with the LEAST operational overhead?

A : Order a 2 Gbps Direct Connect connection for the data center. Configure a virtual private gateway in each VPC. Create a private VIF for each virtual private gateway, and associate the virtual private gateways with the Direct Connect connection. Configure static routes in the VPC route tables and in the data center router.

B : Order a 2 Gbps Direct Connect connection for the data center. Configure a virtual private gateway in each VPC. Create a private VIF for each virtual private gateway, and associate the virtual private gateways with the Direct Connect connection. Configure Open Shortest Path First (OSPF) routing between the private VIF and the data center.

C : Configure a customer gateway and a virtual private gateway in each VPC. Configure an AWS SitetoSite VPN connection between the data center and each VPC. Configure static routes in each VPC route table to point to the subnets in the data center.

D : Configure a customer gateway and a virtual private gateway in each VPC. Configure an AWS SitetoSite VPN connection between the data center and each VPC. Configure BGP routing between the VPCs and the data center.

Answer: A
