Question #273 / 1019

An e-commerce platform is hosting its infrastructure in a single AWS Region and needs to implement a disaster recovery solution using another Region. The company's primary database must be replicated to the DR Region with the lowest possible replication lag. The DR environment should maintain minimal running resources but be capable of rapid scaling during a failover.

Which DR strategy will provide the lowest recovery time objective (RTO) while meeting these requirements?

A

Deploy an Amazon Aurora global database with a pilot light architecture.

B

Deploy an Amazon Aurora global database with a warm standby setup.

C

Configure Amazon RDS Multi-AZ instances with a pilot light architecture.

D

Configure Amazon RDS Multi-AZ instances with a warm standby setup.

Question #833 / 1019

A company is designing an event-driven file processing system. Each uploaded file requires multiple processing steps, such as virus scanning, metadata extraction, and thumbnail generation. An idempotent AWS Lambda function performs each processing step. Each step is independent of the others and requires only a subset of the file event information. The company wants to ensure that each processing step Lambda function has access to only the necessary data and that the system components remain loosely coupled to accommodate future changes. Which solution will meet these requirements?

A

Create an Amazon Simple Queue Service (Amazon SQS) queue for each processing step. Develop a Lambda function to transform the file event data into the required format for each step and publish messages to the corresponding queues. Subscribe each processing step Lambda function to its designated SQS queue.

B

Create an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe all processing step Lambda functions to the topic. Use SNS message filtering to deliver only the relevant data subset to each Lambda function.

C

Create an Amazon EventBridge event bus. Define an event rule for each processing step. Configure an input transformer for each rule to send only the required data to the corresponding target processing step Lambda function.

D

Create a single Amazon Simple Queue Service (Amazon SQS) queue. Implement a Lambda function to subscribe to the queue, transform the file event data, and synchronously invoke all processing step Lambda functions in parallel on separate threads.

Sample Questions

Question #77 / 529

Example Corp. has an on-premises data center connected to VPC Main in their AWS account via a Site-to-Site VPN. They acquire NewCorp, which has VPC New. There is no IP address overlap between the networks. VPC Main and VPC New are peered. Example Corp. wants its on-premises servers to access VPC New. Network ACLs and security groups are properly configured.

Which solution will meet this requirement with the LEAST operational effort?

A

Create a transit gateway. Attach the Site-to-Site VPN, VPC Main, and VPC New to the transit gateway. Update the transit gateway route tables for all networks to add IP range routes for all other networks.

B

Create a transit gateway. Establish a new Site-to-Site VPN connection between the on-premises network and VPC New, and connect the VPN connection to the transit gateway. Add a route to direct traffic to the peered VPCs and an authorization rule to grant access to VPC Main and VPC New.

C

Update the route tables for the Site-to-Site VPN, VPC Main, and VPC New to include routes for all three networks. Enable BGP propagation for all networks and wait up to 5 minutes for propagation to complete.

D

Modify the existing Site-to-Site VPN\u2019s virtual private gateway to include both VPC Main and VPC New. Split the virtual private gateway\u2019s routers between the two VPCs.

Question #148 / 529

A company needs to implement a disaster recovery plan for their primary on-premises application, which uses a PostgreSQL database. The application runs on physical servers that host multiple other services. All on-premises systems use operating systems compatible with Amazon EC2. The company wants to minimize operational complexity while ensuring rapid recovery.

Which solution BEST meets these requirements?

A

Deploy AWS Application Migration Service (MGN) agents on all source servers, including the PostgreSQL database server. Configure replication settings and launch templates. Conduct periodic recovery drills using non-disruptive test instances. Initiate a full cutover to AWS during a disaster.

B

Install AWS Application Migration Service (MGN) agents on the on-premises servers, including the PostgreSQL server. Configure AWS Elastic Disaster Recovery with automated replication and predefined launch settings. Perform regular failover and recovery tests using the most recent synchronized data.

C

Set up an AWS Database Migration Service (AWS DMS) replication instance and a target Amazon RDS for PostgreSQL DB instance. Create a DMS task for continuous data replication. Manually install and configure the application on EC2 instances using compatible AMIs. Use custom scripts to synchronize application state changes.

D

Deploy an AWS Storage Gateway File Gateway on premises. Store application and database files on the gateway. Schedule regular EBS snapshots of the gateway volumes. Provision EC2 instances and restore the application and database from snapshots during a disaster, requiring manual configuration adjustments.

Sample Questions

Question #365 / 557

A developer is creating an AWS Lambda function that is invoked by messages from an Amazon Simple Notification Service (Amazon SNS) topic. The messages represent user profile updates from a social media platform. The developer wants the Lambda function to process only the messages that pertain to phone number changes. Additional subscribers to the SNS topic will process any other messages. Which solution will meet these requirements in the LEAST development effort?

A

Use Lambda event filtering to allow only messages that are related to phone number changes to invoke the Lambda function.

B

Use an SNS filter policy on the Lambda function subscription to allow only messages that are related to phone number changes to invoke the Lambda function.

C

Subscribe an Amazon Simple Queue Service (Amazon SQS) queue to the SNS topic. Configure the SQS queue with a filter policy to allow only messages that are related to phone number changes. Connect the SQS queue to the Lambda function.

D

Configure the Lambda code to check the received message. If the message is not related to a phone number change, configure the Lambda function to publish the message back to the SNS topic for the other subscribers to process.

Question #462 / 557

A company is developing a real-time monitoring system for a distributed application. The system must ingest a continuous stream of performance metrics and allow multiple processing units to analyze the data simultaneously. Each processing unit must be able to recover from failures without missing any metrics, and the solution should avoid duplicating data across processors. The architect also plans to add more processing units later with minimal changes. Which solution meets these requirements?

A

Publish the data to Amazon Simple Queue Service (Amazon SQS).

B

Publish the data to Amazon Data Firehose.

C

Publish the data to Amazon EventBridge.

D

Publish the data to Amazon Kinesis Data Streams.
