Question 1

A company has an application that uses Amazon Elastic File System (Amazon EFS) to store data. The files are 1 GB in size or larger and are accessed often only for the first few days after creation. The application data is shared across a cluster of Linux servers. The company wants to reduce storage costs tor the application. What should a solutions architect do to meet these requirements?

Accepted Answer

Configuring a Lifecycle policy to move files to the EFS Infrequent Access (IA) storage class after 7 days will reduce storage costs while still allowing the files to be accessed when needed.

Question 2

A company wants to use high performance computing (HPC) infrastructure on AWS for financial risk modeling. The company's HPC workloads run on Linux. Each HPC workflow runs on hundreds of AmazonEC2 Spot Instances, is short-lived, and generates thousands of output files that are ultimately stored in persistent storage for analytics and long-term future use. The company seeks a cloud storage solution that permits the copying of on premises data to long-term persistent storage to make data available for processing by all EC2 instances. The solution should also be a high performance file system that is integrated with persistent storage to read and write datasets and output files. Which combination of AWS services meets these requirements?

Accepted Answer

Amazon FSx for Lustre is a high-performance file system that can be integrated with Amazon S3, allowing for efficient processing of large datasets and storage of output files. It is suitable for HPC workloads and can handle the requirements of copying on-premises data to persistent storage.

Question 3

A company recently migrated a message processing system to AWS. The system receives messages into an ActiveMQ queue running on an Amazon EC2 instance. Messages are processed by a consumer application running on Amazon EC2. The consumer application processes the messages and writes results to a MySQL database running on Amazon EC2. The company wants this application to be highly available with low operational complexity. Which architecture offers the HIGHEST availability?

Accepted Answer

This option provides the highest availability by using Amazon MQ with active/standby brokers for message durability, an Auto Scaling group for consumer instances to ensure redundancy and scalability, and Amazon RDS for MySQL with Multi-AZ for database failover and high availability.

Question 4

A company's website hosted on Amazon EC2 instances processes classified data stored in Amazon S3. Due to security concerns, the company requires a private and secure connection between its EC2 resources and Amazon S3. Which solution meets these requirements?

Accepted Answer

Using a VPC endpoint allows secure and private connectivity between EC2 instances and S3 without traversing the public internet, meeting the security requirements.

Question 5

A company needs guaranteed Amazon EC2 capacity in three specific Availability Zones in a specific AWS Region for an upcoming event that will last 1 week. What should the company do to guarantee the EC2 capacity?

Accepted Answer

An On-Demand Capacity Reservation allows you to reserve capacity in specific Availability Zones within a Region, ensuring the required EC2 capacity is available when needed.

Question 6

A company has a service that produces event data. The company wants to use AWS to process the event data as it is received. The data is written in a specific order that must be maintained throughout processing. The company wants to implement a solution that minimizes operational overhead. How should a solution architect accomplish this?

Accepted Answer

Using an Amazon SQS FIFO queue ensures that the order of messages is maintained, which is crucial for the company's requirement. AWS Lambda can process these messages with minimal operational overhead.

Question 7

A solutions architect is designing the architecture of a new application being deployed to the AWS Cloud. The application will run on Amazon EC2 On-Demand Instances and will automatically scale across multiple Availability Zones. The EC2 instances will scale up and down frequently throughout the day. An Application Load Balancer (ALB) will handle the load distribution. The architecture needs to support distributed session data management. The company is willing to make changes to code if needed. What should the solutions architect do to ensure that the architecture supports distributed session data management?

Accepted Answer

Amazon ElastiCache can be used to store session data in a distributed manner, allowing multiple instances to access the same session data, which is ideal for applications that scale across multiple Availability Zones.

Question 8

A company is creating a web application that will store a large number of images in Amazon S3. The images will be accessed by users over variable periods of time. The company wants to: Retain all the images Incur no cost for retrieval. Have minimal management overhead. Have the images available with no impact on retrieval time. Which solution meets these requirements?

Accepted Answer

S3 Intelligent-Tiering automatically moves data between two access tiers when access patterns change, ensuring cost efficiency without retrieval costs or management overhead, and with no impact on retrieval time.

Question 9

A company wants a storage option that enables its data science team to analyze its data on premises and in the AWS Cloud. The team needs to be able to run statistical analyses by using the data on premises and by using a fleet of Amazon EC2 instances across multiple Availability Zones.

Question 11

A company hosts its multi-tier public web application in the AWS Cloud. The web application runs on Amazon EC2 instances and its database runs on Amazon RDS. The company is anticipating a large increase in sales during an upcoming holiday weekend. A solutions architect needs to build a solution to analyze the performance of the web application with a granularity of no more than 2 minutes. What should the solutions architect do to meet this requirement?

Accepted Answer

Enabling detailed monitoring on EC2 instances provides metrics at a 1-minute granularity, which meets the requirement for analyzing performance with a granularity of no more than 2 minutes. CloudWatch metrics can then be used for further analysis.

Question 12

A company wants to build an online marketplace application on AWS as a set of loosely coupled microservices. For this application, when a customer submits a new order, two microservices should handle the event simultaneously. The Email microservice will send a confirmation email, and the OrderProcessing microservice will start the order delivery process. If a customer cancels an order, the OrderCancelation and Email microservices should handle the event simultaneously. A solutions architect wants to use Amazon Simple Queue Service (Amazon SQS) and Amazon Simple Notification Service (Amazon SNS) to design the messaging between the microservices. How should the solutions architect design the solution?

Amazon EFS (Elastic File System) supports the NFS protocol, is highly scalable, and allows multiple EC2 instances to access the same file system simultaneously.

Question 19

A company has an on-premises application that collects data and stores it to an on-premises NFS server. The company recently set up a 10 Gbps AWS Direct Connect connection. The company is running out of storage capacity on premises. The company needs to migrate the application data from on premises to the AWS Cloud while maintaining low-latency access to the data from the on-premises application. What should a solutions architect do to meet these requirements?

Accepted Answer

AWS Storage Gateway with a file gateway allows the on-premises application to access data stored in Amazon S3 using NFS, providing a seamless integration and low-latency access while offloading storage to the cloud.
