AWS Certified Solutions Architect - Professional Questions and Answers

Question 197

An education company is running a web application used by college students around the world. The application runs in an Amazon Elastic Container Service (Amazon ECS) cluster in an Auto Scaling group behind an Application Load Balancer (ALB). A system administrator detected a weekly spike in the number of failed logic attempts. Which overwhelm the application’s authentication service. All the failed login attempts originate from about 500 different IP addresses that change each week. A solutions architect must prevent the failed login attempts from overwhelming the authentication service.

Which solution meets these requirements with the MOST operational efficiency?

Options:

A.

Use AWS Firewall Manager to create a security group and security group policy to deny access from the IP addresses.

B.

Create an AWS WAF web ACL with a rate-based rule, and set the rule action to Block. Connect the web ACL to the ALB.

C.

Use AWS Firewall Manager to create a security group and security group policy to allow access only to specific CIDR ranges.

D.

Create an AWS WAF web ACL with an IP set match rule, and set the rule action to Block. Connect the web ACL to the ALB.

Question 198

A company has used infrastructure as code (IaC) to provision a set of two Amazon EC2 instances. The instances have remained the same for several years.

The company ' s business has grown rapidly in the past few months. In response the company ' s operations team has implemented an Auto Scaling group to manage the sudden increases in traffic. Company policy requires a monthly installation of security updates on all operating systems that are running.

The most recent security update required a reboot. As a result, the Auto Scaling group terminated the instances and replaced them with new, unpatched instances.

Which combination of steps should a solutions architect recommend to avoid a recurrence of this issue? (Choose two.)

Options:

A.

Modify the Auto Scaling group by setting the Update policy to target the oldest launch configuration for replacement.

B.

Create a new Auto Scaling group before the next patch maintenance. During the maintenance window, patch both groups and reboot the instances.

C.

Create an Elastic Load Balancer in front of the Auto Scaling group. Configure monitoring to ensure that target group health checks return healthy after the Auto Scaling group replaces the terminated instances.

D.

Create automation scripts to patch an AMI, update the launch configuration, and invoke an Auto Scaling instance refresh.

E.

Create an Elastic Load Balancer in front of the Auto Scaling group. Configure termination protection on the instances.

Question 199

A company is creating a REST API to share information with six of its partners based in the United States. The company has created an Amazon API Gateway Regional endpoint. Each of the six partners will access the API once per day to post daily sales figures.

After initial deployment, the company observes 1.000 requests per second originating from 500 different IP addresses around the world. The company believes this traffic is originating from a botnet and wants to secure its API while minimizing cost.

Which approach should the company take to secure its API?

Options:

A.

Create an Amazon CloudFront distribution with the API as the origin. Create an AWS WAF web ACL with a rule lo block clients thai submit more than fiverequests per day. Associate the web ACL with the CloudFront distnbution. Configure CloudFront with an origin access identity (OAI) and associate it with the distribution. Configure API Gateway to ensure only the OAI can run the POST method.

B.

Create an Amazon CloudFront distribution with the API as the origin. Create an AWS WAF web ACL with a rule to block clients that submit more than five requests per day. Associate the web ACL with the CloudFront distnbution. Add a custom header to the CloudFront distribution populated with an API key. Configure the API to require an API key on the POST method.

C.

Create an AWS WAF web ACL with a rule to allow access to the IP addresses used by the six partners. Associate the web ACL with the API. Create a resource policy with a request limit and associate it with the API. Configure the API to require an API key on the POST method.

D.

Create an AWS WAF web ACL with a rule to allow access to the IP addresses used by the six partners. Associate the web ACL with the API. Create a usage plan with a request limit and associate it with the API. Create an API key and add it to the usage plan.

Question 200

A company needs a hybrid DNS architecture. The architecture must include the company’s on-premises network and a VPC. An AWS Site-to-Site VPN connection connects the VPC to the on-premises network. The company already hosts the onprem.mydc.com domain name on premises.

The company wants to host the myvpc.example.com domain name in the company’s AWS account and resolve it to the VPC. The company also needs the on-premises devices to resolve DNS queries to the myvpc.example.com domain.

Which combination of steps will meet these requirements? Select THREE.

Options:

A.

Create an Amazon Route 53 private hosted zone for the myvpc.example.com domain. Associate the domain with the VPC.

B.

Create an Amazon Route 53 public hosted zone for the myvpc.example.com domain. Associate the domain with the VPC.

C.

Use Amazon Route 53 Resolver to create an inbound endpoint in the AWS Region of the VPC.

D.

Use Amazon Route 53 Resolver to create an outbound endpoint in the AWS Region of the VPC.

E.

Use Amazon Route 53 Resolver to create a forwarding rule for the Route 53 private hosted zone domain and IP addresses of the outbound endpoint.

F.

Configure the on-premises DNS resolvers with a conditional forwarding rule for DNS queries for the Amazon Route 53 private hosted zone domain and IP addresses of the inbound endpoint.
