Question 3

An application publishes Amazon SNS messages in response to several events. An AWS Lambda function subscribes to these messages. Occasionally the function will fail while processing a message, so the original event message must be preserved for root cause analysis. What architecture will meet these requirements without changing the workflow?

Accepted Answer

An SQS queue can preserve the original message for later processing if the Lambda function fails.

Question 4

You need to select and configure compute resources for a set of batch processing jobs. These jobs take around 2 hours to complete and are run nightly. You want to minimize service costs. What should you do?

Accepted Answer

Preemptible VM instances are cost-effective for batch processing jobs as they are significantly cheaper than regular instances and are suitable for workloads that can be interrupted, like nightly batch jobs.

Question 5

A Solutions Architect is designing a photo application on AWS. Every time a user uploads a photo to Amazon S3, the Architect must insert a new item to a DynamoDB table. Which AWS-managed service is the BEST fit to insert the item?

Accepted Answer

AWS Lambda is the best fit for this task as it can be triggered by S3 events to automatically execute code that inserts a new item into a DynamoDB table without the need for managing servers.

Question 6

A legacy application running in premises requires a Solutions Architect to be able to open a firewall to allow access to several Amazon S3 buckets. The Architect has a VPN connection to AWS in place. How should the Architect meet this requirement?

Accepted Answer

An IAM role can be created to allow access to Amazon S3 from the corporate network.

Question 7

You have 32 GB of data in a single file that you need to upload to a Nearline Storage bucket. The WAN connection you are using is rated at 1 Gbps, and you are the only one on the connection. You want to use as match of the rated 1 Gbps as possible to transfer the file rapidly. How should you upload the file?

Accepted Answer

Enabling parallel composite uploads with gsutil allows the file to be split into multiple components, which can be uploaded in parallel, maximizing the use of the available bandwidth and speeding up the transfer.

Question 8

An application requires block storage for file updates. The data is 500 GB and must continuously sustain 100 MiB/s of aggregate read/write operations. Which storage option is appropriate for this application?

Accepted Answer

Amazon EBS (Elastic Block Store) is designed for block storage and can handle the required 100 MiB/s read/write operations, making it suitable for applications needing block storage for file updates.

Question 9

You want to configure 10 Compute Engine instances for availability when maintenance occurs. Your requirements state that these instances should attempt to automatically restart if they crash. Also, the instances should be highly available including during system maintenance. What should you do?

Accepted Answer

The answer of You want to configure 10 Compute Engine...

Question 10

A Solutions Architect is designing the architecture for a new three-tier web-based e-commerce site that must be available 24/7. Requests are expected to range from 100 to 10,000 each minute. Usage can vary depending on time of day, holidays, and promotions. The design should be able to handle these volumes, with the ability to handle higher volumes if necessary. How should the Architect design the architecture to ensure the web tier is cost-optimized and can handle the expected traffic? (Choose two.)

Accepted Answer

A) Launch Amazon EC2 instances in an Auto Scaling group behind an ELB. This will allow the web tier to scale up or down automatically based on demand, ensuring that the site is always available and responsive.C) Create an CloudFront distribution pointing to static content in Amazon S3. This will offload the serving of static content from the web tier, reducing the load on the web servers and improving performance.

Question 11

You need to monitor resources that are distributed over different projects in Google Cloud Platform. You want to consolidate reporting under the same Stackdriver Monitoring dashboard. What should you do?

Accepted Answer

The answer of You need to monitor resources that are...

Question 12

A company requires that the source, destination, and protocol of all IP packets be recorded when traversing a private subnet. What is the MOST secure and reliable method of accomplishing this goal.

Accepted Answer

VPC flow logs are specifically designed to capture information about the IP traffic going to and from network interfaces in a VPC, including source, destination, and protocol, making them the most secure and reliable method for this requirement.

Question 13

A company is launching a static website using the zone apex (mycompany.com). The company wants to use Amazon Route 53 for DNS. Which steps should the company perform to implement a scalable and cost-effective solution? (Choose two.)

Accepted Answer

Using an ELB with Auto Scaling or an S3 bucket ensures scalability and cost-effectiveness.

Question 14

After reviewing their logs, a startup company noticed large, random spikes in traffic to their web application. The company wants to configure a cost-efficient Auto Scaling solution to support high availability of the web application. Which scaling plan should a Solutions Architect recommend to meet the company's needs?

Accepted Answer

Dynamic scaling automatically adjusts the number of instances in response to changes in demand, making it cost-efficient and suitable for handling random traffic spikes.

Question 15

A retail company has sensors placed in its physical retail stores. The sensors send messages over HTTP when customers interact with in-store product displays. A Solutions Architect needs to implement a system for processing those sensor messages; the results must be available for the Data Analysis team. Which architecture should be used to meet these requirements?

Accepted Answer

Using Amazon API Gateway as the HTTP endpoint allows for scalable and secure handling of incoming messages. Triggering an AWS Lambda function provides a serverless way to process the messages, and storing results in Amazon DynamoDB offers a scalable and reliable database solution for the Data Analysis team.

Question 17

A media company asked a Solutions Architect to design a highly available storage solution to serve as a centralized document store for their Amazon EC2 instances. The storage solution needs to be POSIX-compliant, scale dynamically, and be able to serve up to 100 concurrent EC2 instances. Which solution meets these requirements?

Accepted Answer

Amazon Elastic File System (Amazon EFS) is POSIX-compliant, scales dynamically, and can be mounted by multiple EC2 instances concurrently, making it suitable for the described requirements.
