Question #848 / 1019

A company operates its application on Oracle Database Enterprise Edition and plans to migrate to AWS using the Bring Your Own License (BYOL) model. The application depends on proprietary database extensions that require direct access to the underlying operating system. A solutions architect must design the migration strategy. Which solution is MOST cost-effective?

A

Migrate to Amazon RDS for Oracle using AWS DMS. Replace the proprietary extensions with Amazon EC2-hosted services.

B

Migrate to Amazon RDS Custom for Oracle using native tools. Configure the database environment to accommodate the proprietary extensions.

C

Migrate to Amazon Aurora PostgreSQL using AWS DMS. Modify the application to eliminate dependency on the proprietary extensions.

D

Migrate to Amazon DynamoDB using AWS DMS. Redesign the application to use NoSQL structures instead of the proprietary extensions.

Question #749 / 1019

A company’s web application runs on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). The application is fronted by a CloudFront distribution with the ALB as its origin. AWS WAF is configured to mitigate cross-site scripting (XSS) attacks. Security logs recently identified a malicious external IP address that must be blocked from accessing the application.

What should a solutions architect do to block the malicious IP address effectively?

A

Update the network ACL associated with the CloudFront distribution to include a deny rule for the malicious IP address.

B

Modify the AWS WAF configuration to add an IP match condition that blocks the malicious IP address.

C

Update the network ACL for the EC2 instances in the ALB\u2019s target groups to deny traffic from the malicious IP address.

D

Modify the security groups for the EC2 instances in the ALB\u2019s target groups to deny ingress traffic from the malicious IP address.

Sample Questions

Question #250 / 529

A company is deploying a distributed database that requires consistent high-throughput and low-latency communication between five Amazon EC2 instances within the same AWS Region. The solution does not need to account for fault tolerance.

Which architecture will satisfy these requirements?

A

Deploy five EC2 instances within a cluster placement group, using an instance type that supports enhanced networking capabilities.

B

Deploy five EC2 instances in an Auto Scaling group across a single Availability Zone, attaching an additional elastic network interface to each instance.

C

Deploy five EC2 instances within a partition placement group, selecting an instance type that supports enhanced networking capabilities.

D

Deploy five EC2 instances across a spread placement group, attaching an additional elastic network interface to each instance.

Question #47 / 529

A company is developing a serverless application hosted on AWS Lambda within a VPC. The application must communicate with an external API that mandates all requests originate from a single static public IPv4 address. The company needs to ensure the Lambda functions can securely access the API while adhering to this requirement.

Which solution will enable the application to meet the external provider's condition?

A

Deploy a NAT gateway in a public subnet. Assign an Elastic IP address to the NAT gateway. Update the VPC route tables to direct outbound traffic from the Lambda function's subnet to the NAT gateway.

B

Create an egress-only internet gateway. Attach an Elastic IP address to the gateway. Modify the Lambda function's security group to route traffic through the egress-only internet gateway.

C

Configure an internet gateway with an Elastic IP address. Update the Lambda function's elastic network interface to associate with the internet gateway's Elastic IP address.

D

Attach an internet gateway to the VPC. Assign an Elastic IP address to the internet gateway. Configure the main route table in the VPC to route all outbound traffic through the internet gateway.

Sample Questions

Question #182 / 557

A company built an API on AWS using Amazon CloudFront, Amazon API Gateway, and AWS Lambda. The API consistently receives at least five requests per second, and many users submit identical data via the POST method. The developer wants to cache these POST responses to reduce backend load and improve performance. Which solution meets these requirements?

A

Enable CloudFront caching with custom cache policies that include the POST method and relevant headers.

B

Modify the API Gateway stage settings to override the default cache behavior and enable caching for the POST method.

C

Store recent POST responses in the Lambda function's /tmp storage and configure the function to serve cached responses when possible.

D

Use Amazon ElastiCache to store POST responses and update the Lambda function to retrieve cached data from ElastiCache.

Question #198 / 557

A developer has designed an AWS Lambda function that interacts with an Amazon RDS PostgreSQL DB instance. During load testing, the database returns an error due to exceeding the maximum number of connections. Which solution resolves this issue with the LEAST operational effort?

A

Set up a standby replica for the DB instance and direct read queries to the replica.

B

Migrate the database to Amazon Aurora Serverless to automatically handle scaling.

C

Enable Multi-AZ deployment for the RDS PostgreSQL DB instance.

D

Use Amazon RDS Proxy and route database requests through the proxy.
