Use a bucket policy to grant permission to users in its account as well as to users in
another account - Answers :A company wants to grant access to an Amazon S3 bucket
to users in its own AWS account as well as to users in another AWS account. Which of
the following options can be used to meet this requirement?
Leverage AWS Database Migration Service (AWS DMS) as a bridge between Amazon
S3 and Amazon Kinesis Data Streams - Answers :A Big Data analytics company writes
data and log files in Amazon S3 buckets. The company now wants to stream the
existing data files as well as any ongoing file updates from Amazon S3 to Amazon
Kinesis Data Streams.
As a Solutions Architect, which of the following would you suggest as the fastest
possible way of building a solution for this requirement?
Amazon CloudFront can route to multiple origins based on the content type
Use an origin group with primary and secondary origins to configure Amazon
CloudFront for high-availability and failover
Use field level encryption in Amazon CloudFront to protect sensitive data for specific
content - Answers :The engineering team at a social media company has recently
migrated to AWS Cloud from its on-premises data center. The team is evaluating
Amazon CloudFront to be used as a CDN for its flagship application. The team has
hired you as an AWS Certified Solutions Architect - Associate to advise on Amazon
CloudFront capabilities on routing, security, and high availability.
Which of the following would you identify as correct regarding Amazon CloudFront?
(Select three)
Select a cluster placement group while launching Amazon EC2 instances - Answers :An
IT company runs a high-performance computing (HPC) workload on AWS. The
workload requires high network throughput and low-latency network performance along
with tightly coupled node-to-node communications. The Amazon EC2 instances are
properly sized for compute and storage capacity and are launched using default
options.
Which of the following solutions can be used to improve the performance of the
workload?
Create an Amazon Machine Image (AMI) after installing the software and copy the AMI
across all Regions. Use this Region-specific AMI to run the recovery process in the
respective Regions - Answers :The engineering team at a global e-commerce company
, is currently reviewing their disaster recovery strategy. The team has outlined that they
need to be able to quickly recover their application stack with a Recovery Time
Objective (RTO) of 5 minutes, in all of the AWS Regions that the application runs. The
application stack currently takes over 45 minutes to install on a Linux system.
As a Solutions architect, which of the following options would you recommend as the
disaster recovery strategy?
Create an Amazon CloudFront distribution - Answers :A photo hosting service publishes
a collection of beautiful mountain images, every month, that aggregate over 50
gigabytes in size and downloaded all around the world. The content is currently hosted
on Amazon EFS and distributed by Elastic Load Balancing (ELB) and Amazon EC2
instances. The website is experiencing high load each month and very high network
costs.
As a Solutions Architect, what can you recommend that won't force an application
refactor and reduce network costs and Amazon EC2 load drastically?
Instance Store - Answers :As a Solutions Architect, you are tasked to design a
distributed application that will run on various Amazon EC2 instances. This application
needs to have the highest performance local disk to cache data. Also, data is copied
through an Amazon EC2 to EC2 replication mechanism. It is acceptable if the instance
loses its data when stopped or terminated.
Which storage solution do you recommend?
Amazon Kinesis with Amazon Simple Notification Service (Amazon SNS) - Answers :An
Internet of Things (IoT) company would like to have a streaming system that performs
real-time analytics on the ingested IoT data. Once the analytics is done, the company
would like to send notifications back to the mobile applications of the IoT device owners.
As a solutions architect, which of the following AWS technologies would you
recommend to send these notifications to the mobile applications?
Use an Auto Scaling Group - Answers :The engineering team at a leading e-commerce
company is anticipating a surge in the traffic because of a flash sale planned for the
weekend. You have estimated the web traffic to be 10x. The content of your website is
highly dynamic and changes very often.
As a Solutions Architect, which of the following options would you recommend to make
sure your infrastructure scales for that day?
Use Amazon RDS Read Replicas - Answers :A company has developed a popular
photo-sharing website using a serverless pattern on the AWS Cloud using Amazon API
Gateway and AWS Lambda. The backend uses an Amazon RDS PostgreSQL
