Question 204

A company owns an asynchronous API that is used to ingest user requests and, based on the request type, dispatch requests to the appropriate microservice for processing. The company is using Amazon API Gateway to deploy the API front end, and an AWS Lambda function that invokes Amazon DynamoDB to store user requests before dispatching them to the processing microservices.

The company provisioned as much DynamoDB throughput as its budget allows, but the company is still experiencing availability issues and is losing user requests.

What should a solutions architect do to address this issue without impacting existing users?

Options:

Add throttling on the API Gateway with server-side throttling limits.

Use DynamoDB Accelerator (DAX) and Lambda to buffer writes to DynamoDB.

Create a secondary index in DynamoDB for the table with the user requests.

Use the Amazon Simple Queue Service (Amazon SQS) queue and Lambda to buffer writes to DynamoDB.

Question 205

A company wants to migrate its MySQL database from on premises to AWS. The company recently experienced a database outage that significantly impacted the business. To ensure this does not happen again, the company wants a reliable database solution on AWS that minimizes data loss and stores every transaction on at least two nodes.

Which solution meets these requirements?

Options:

Create an Amazon RDS DB instance with synchronous replication to three nodes in three Availability Zones.

Create an Amazon RDS MySQL DB instance with Multi-AZ functionality enabled to synchronously replicate the data.

Create an Amazon RDS MySQL DB instance and then create a read replica in a separate AWS Region that synchronously replicates the data.

Create an Amazon EC2 instance with a MySQL engine installed that triggers an AWS Lambda function to synchronously replicate the data to an Amazon RDS MySQL DB instance.

Hey, I used Cramkey Dumps to prepare for my recent exam and I passed it.

Lewis Sep 11, 2024

Yeah, I used these dumps too. And I have to say, I was really impressed with the results.

Vienna

I highly recommend them. They are offering exact questions that we need to prepare our exam.

Jensen Oct 9, 2024

That's great. I think I'll give Cramkey a try next time I take a certification exam. Thanks for the recommendation!

Annabel

I recently used them for my exam and I passed it with excellent score. I am impressed.

Amirah Oct 28, 2024

I passed too. The questions I saw in the actual exam were exactly the same as the ones in the Cramkey Dumps. I was able to answer the questions confidently because I had already seen and studied them.

Fatima

Hey I passed my exam. The world needs to know about it. I have never seen real exam questions on any other exam preparation resource like I saw on Cramkey Dumps.

Niamh Oct 15, 2024

That's true. Cramkey Dumps are simply the best when it comes to preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

Rae

I tried using Cramkey dumps for my recent certification exam and I found them to be more accurate and up-to-date compared to other dumps I've seen. Passed the exam with wonderful score.

Rayyan Sep 14, 2024

I see your point. Thanks for sharing your thoughts. I might give it a try for my next certification exam.

Question 206

A solutions architect needs to implement a solution to reduce a company's storage costs. All the company's data is in the Amazon S3 Standard storage class. The company must keep all data for at least 25 years. Data from the most recent 2 years must be highly available and immediately retrievable.

Which solution will meet these requirements?

Options:

Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive immediately.

Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 2 years.

Use S3 Intelligent-Tiering. Activate the archiving option to ensure that data is archived in S3 Glacier Deep Archive.

Set up an S3 Lifecycle policy to transition objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) immediately and to S3 Glacier Deep Archive after 2 years.

Question 207

A company stores its application logs in an Amazon CloudWatch Logs log group. A new policy requires the company to store all application logs in Amazon OpenSearch Service (Amazon Elasticsearch Service) in near-real time.

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

Options:

Configure a CloudWatch Logs subscription to stream the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service).

Create an AWS Lambda function. Use the log group to invoke the function to write the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service).

Create an Amazon Kinesis Data Firehose delivery stream. Configure the log group as the delivery stream's source. Configure Amazon OpenSearch Service (Amazon Elasticsearch Service) as the delivery stream's destination.

Install and configure Amazon Kinesis Agent on each application server to deliver the logs to Amazon Kinesis Data Streams. Configure Kinesis Data Streams to deliver the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service)
