Question 1

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 2

A department in your company has created a new account that is not part of the organization's consolidated billing family. The department has also created a VPC for its workload. Access is restricted by network access control lists to the department's on-premises private IP allocation. An AWS Direct Connect private virtual interface for this VPC advertises a default route to the company network. When the department downloads data from an Amazon Elastic Compute Cloud(EC2) instance in its new VPC, what are the associated charges?

A : company pays Internet Data Out charges.

B : company pays AWS Direct Connect Data Out charges.

C : department pays Internet Data Out charges.

D : department pays AWS Direct Connect Data Out charges.

Answer: D

Question 3

A company hosts a web application that runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). The instances are in an Auto Scaling group. The company uses an Amazon CloudFront distribution with the ALB as an origin. The application recently experienced an attack. In response, the company associated an AWS WAF web ACL with the CloudFront distribution. The company needs to use Amazon Athena to analyze application attacks that AWS WAF detects. Which solution will meet this requirement?

A : Configure the ALB and the EC2 instance subnets to produce VPC flow logs. Configure the VPC flow logs to deliver logs to an Amazon S3 bucket for log analysis.

B : Create a trail in AWS CloudTrail to capture data events. Configure the trail to deliver logs to an Amazon S3 bucket for log analysis.

C : Configure the AWS WAF web ACL to deliver logs to an Amazon Kinesis Data Firehose delivery stream. Configure the stream to deliver the data to an Amazon S3 bucket for log analysis.

D : Turn on access logging for the ALB. Configure the access logs to deliver the logs to an Amazon S3 bucket for log analysis.

Answer: D

Question 4

A company uses AWS Direct Connect to connect its corporate network to multiple VPCs in the same AWS account and the same AWS Region. Each VPC uses its own private VIF and its own virtual LAN on the Direct Connect connection. The company has grown and will soon surpass the limit of VPCs and private VIFs for each connection. What is the MOST scalable way to add VPCs with on-premises connectivity?

A : ovision a new Direct Connect connection to handle the additional VPCs. Use the new connection to connect additional VPCs.

B : eate virtual private gateways for each VPC that is over the service quota. Use AWS Site-to-Site VPN to connect the virtual private gateways to the corporate network.

C : eate a Direct Connect gateway, and add virtual private gateway associations to the VPCs. Configure a private VIF to connect to the corporate network.

D : eate a transit gateway, and attach the VPCs. Create a Direct Connect gateway, and associate it with the transit gateway. Create a transit VIF to the Direct Connect gateway.

Answer: D

Question 5

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.
