Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q542-Q547):

NEW QUESTION # 542
A company recently launched Linux-based application instances on Amazon EC2 in a private subnet and launched a Linux-based bastion host on an Amazon EC2 instance in a public subnet of a VPC. A solutions architect needs to connect from the on-premises network, through the company's internet connection, to the bastion host, and to the application servers. The solutions architect must make sure that the security groups of all the EC2 instances will allow that access.
Which combination of steps should the solutions architect take to meet these requirements?
(Choose two.)

Answer: A,B

Explanation:
C because from on-prem network to bastion through internet (using on-prem resource's public IP).
D because bastion and ec2 is in same VPC, meaning bastion can communicate to EC2 via it's private IP address.


NEW QUESTION # 543
A music publishing company is building a multitier web application that requires a key-value store which will save the document models. Each model is composed of band ID, album ID, song ID, composer ID, lyrics, and other data. The web tier will be hosted in an Amazon ECS cluster with AWS Fargate launch type.
Which of the following is the MOST suitable setup for the database-tier?

Answer: A

Explanation:
Amazon DynamoDB is a fast and flexible NoSQL database service for all applications that need consistent, single-digit millisecond latency at any scale. It is a fully managed cloud database and supports both document and key-value store models. Its flexible data model, reliable performance, and automatic scaling of throughput capacity makes it a great fit for mobile, web, gaming, ad tech, IoT, and many other applications.

Hence, the correct answer is: Launch a DynamoDB table.
The option that says: Launch an Amazon RDS database with Read Replicas is incorrect because this is a relational database. This is not suitable to be used as a key-value store. A better option is to use DynamoDB as it supports both document and key-value store models.
The option that says: Use Amazon WorkDocs to store the document models is incorrect because Amazon WorkDocs simply enables you to share content, provide rich feedback, and collaboratively edit documents. It is not a key-value store like DynamoDB.
The option that says: Launch an Amazon Aurora Serverless database is incorrect because this type of database is not suitable to be used as a key-value store. Amazon Aurora Serverless is an on-demand, auto-scaling configuration for Amazon Aurora where the database will automatically start-up, shut down, and scale capacity up or down based on your application's needs. It enables you to run your database in the cloud without managing any database instances. It's a simple, cost-effective option for infrequent, intermittent, or unpredictable workloads and not as a key-value store. References:

NEW QUESTION # 544
[Design High-Performing Architectures]
A company stores multiple Amazon Machine Images (AMIs) in an AWS account to launch its Amazon EC2 instances. The AMIs contain critical data and configurations that are necessary for the company's operations. The company wants to implement a solution that will recover accidentally deleted AMIs quickly and efficiently.
Which solution will meet these requirements with the LEAST operational overhead?

Answer: C

Explanation:
Recycle Bin is a data recovery feature that enables you to restore accidentally deleted Amazon EBS snapshots and EBS-backed AMIs. When using Recycle Bin, if your resources are deleted, they are retained in the Recycle Bin for a time period that you specify before being permanently deleted. You can restore a resource from the Recycle Bin at any timebefore its retention period expires. This solution has the least operational overhead, as you do not need to create, copy, or upload any additional resources. You can also manage tags and permissions for AMIs in the Recycle Bin. AMIs in the Recycle Bin do not incur any additional charges. Reference:
Recover AMIs from the Recycle Bin
Recover an accidentally deleted Linux AMI


NEW QUESTION # 545
A company wants to host a scalable web application on AWS. The application will be accessed by users from different geographic regions of the world. Application users will be able to download and upload unique data up to gigabytes in size. The development team wants a cost-effective solution to minimize upload and download latency and maximize performance.
What should a solutions architect do to accomplish this?

Answer: B

Explanation:
This answer is correct because it meets the requirements of hosting a scalable web application that can handle large data transfers from different geographic regions. Amazon EC2 provides scalable compute capacity for hosting web applications. Auto Scaling can automatically adjust the number of EC2 instances based on the demand and traffic patterns. Amazon CloudFront is a content delivery network (CDN) that can cache static and dynamic content at edge locations closer to the users, reducing latency and improving performance. CloudFront can also use S3 Transfer Acceleration to speed up the transfers between S3 buckets and CloudFront edge locations.

NEW QUESTION # 546
A company hosts a three-tier web application that includes a PostgreSQL database The database stores the metadata from documents The company searches the metadata for key terms to retrieve documents that the company reviews in a report each month The documents are stored in Amazon S3 The documents are usually written only once, but they are updated frequency The reporting process takes a few hours with the use of relational queries The reporting process must not affect any document modifications or the addition of new documents.
What are the MOST operationally efficient solutions that meet these requirements? (Select TWO )

Answer: A,B
