Which of the following describes a physical location around the world where AWS
clusters data centers?
1. Endpoint
2. Collection
3. Fleet
4. Region - CORRECT ANSWES -- 4
<strong>D.</strong><br>A region is a named set of AWS resources in the same
geographical area. A region comprises at least two availability zones. Endpoint,
Collection, and Fleet do not describe a physical location around the world where AWS
clusters data centers.
Each AWS region is composed of two or more locations that offer organizations the
ability to operate production systems that are more highly available, fault tolerant, and
scalable than would be possible using a single data center. What are these locations
called?
1. Availability zones
2. Replication areas
3. Geographic districts
4. Compute centers - CORRECT ANSWES -- 1
<strong>A.</strong><br>An availability zone is a distinct location within a region that is
insulated from failures in other availability zones and provides inexpensive, low-latency
network connectivity to other availability zones in the same region. Replication areas,
geographic districts, and compute centers are not terms used to describe AWS data
center locations.
What is the deployment term for an environment that extends an existing on-premises
infrastructure into the cloud to connect cloud resources to internal systems?
1. All-in deployment
2. Hybrid deployment
3. On-premises deployment
4. Scatter deployment - CORRECT ANSWES -- 2
<strong>B.</strong><br>A hybrid deployment is a way to connect infrastructure and
applications between cloud-based resources and existing resources that are not located
in the cloud. An all-in deployment refers to an environment that exclusively runs in the
,cloud. An on-premises deployment refers to an environment that runs exclusively in an
organization's data center.
Which AWS Cloud service allows organizations to gain system-wide visibility into
resource utilization, application performance, and operational health?
1. AWS Identity and Access Management (IAM)
2. Amazon Simple Notification Service (Amazon SNS)
3. Amazon CloudWatch
4. AWS CloudFormation - CORRECT ANSWES -- 3
<strong>C.</strong><br>Amazon CloudWatch is a monitoring service for AWS Cloud
resources and the applications organizations run on AWS. It allows organizations to
collect and track metrics, collect and monitor log files, and set alarms. AWS IAM,
Amazon SNS, and AWS CloudFormation do not provide visibility into resource
utilization, application performance, and the operational health of your AWS resources.
Which of the following AWS Cloud services is a fully managed NoSQL database
service?
1. Amazon Simple Queue Service (Amazon SQS)
2. Amazon DynamoDB
3. Amazon ElastiCache
4. Amazon Relational Database Service (Amazon RDS) - CORRECT ANSWES -- 2
<strong>B.</strong><br>Amazon DynamoDB is a fully managed, fast, and flexible
NoSQL database service for all applications that need consistent, single-digit
millisecond latency at any scale. Amazon SQS, Amazon ElastiCache, and Amazon
RDS do not provide a NoSQL database service. Amazon SQS is a managed message
queuing service. Amazon ElastiCache is a service that provides in-memory cache in the
cloud. Finally, Amazon RDS provides managed relational databases.
Your company experiences fluctuations in traffic patterns to their e-commerce website
based on flash sales. What service can help your company dynamically match the
required compute capacity to the spike in traffic during flash sales?
1. Auto Scaling
2. Amazon Glacier
3. Amazon Simple Notification Service (Amazon SNS)
4. Amazon Virtual Private Cloud (Amazon VPC) - CORRECT ANSWES -- 1
<strong>A.</strong><br>Auto Scaling helps maintain application availability and allows
organizations to scale Amazon Elastic Compute Cloud (Amazon EC2) capacity up or
down automatically according to conditions defined for the particular workload. Not only
can it be used to help ensure that the desired number of Amazon EC2 instances are
running, but it also allows resources to scale in and out to match the demands of
dynamic workloads. Amazon Glacier, Amazon SNS, and Amazon VPC do not provide
services to scale compute capacity automatically.
Your company provides an online photo sharing service. The development team is
looking for ways to deliver image files with the lowest latency to end users so the
,website content is delivered with the best possible performance. What service can help
speed up distribution of these image files to end users around the world?
1. Amazon Elastic Compute Cloud (Amazon EC2)
2. Amazon Route 53
3. AWS Storage Gateway
4. Amazon CloudFront - CORRECT ANSWES -- 4
<strong>D.</strong><br>Amazon CloudFront is a web service that provides a CDN to
speed up distribution of your static and dynamic web content—for
example, .html, .css, .php, image, and media files—to end users. Amazon CloudFront
delivers content through a worldwide network of edge locations. Amazon EC2, Amazon
Route 53, and AWS Storage Gateway do not provide CDN services that are required to
meet the needs for the photo sharing service.
Your company runs an Amazon Elastic Compute Cloud (Amazon EC2) instance
periodically to perform a batch processing job on a large and growing filesystem. At the
end of the batch job, you shut down the Amazon EC2 instance to save money but need
to persist the filesystem on the Amazon EC2 instance from the previous batch runs.
What AWS Cloud service can you leverage to meet these requirements?
1. Amazon Elastic Block Store (Amazon EBS)
2. Amazon DynamoDB
3. Amazon Glacier
4. AWS CloudFormation - CORRECT ANSWES -- 1
<strong>A.</strong><br>Amazon EBS provides persistent block-level storage volumes
for use with Amazon EC2 instances on the AWS Cloud. Amazon DynamoDB, Amazon
Glacier, and AWS CloudFormation do not provide persistent block-level storage for
Amazon EC2 instances. Amazon DynamoDB provides managed NoSQL databases.
Amazon Glacier provides low-cost archival storage. AWS CloudFormation gives
developers and systems administrators an easy way to create and manage a collection
of related AWS resources.
What AWS Cloud service provides a logically isolated section of the AWS Cloud where
organizations can launch AWS resources in a virtual network that they define?
1. Amazon Simple Workflow Service (Amazon SWF)
2. Amazon Route 53
3. Amazon Virtual Private Cloud (Amazon VPC)
4. AWS CloudFormation - CORRECT ANSWES -- 3
<strong>C.</strong><br>Amazon VPC lets organizations provision a logically isolated
section of the AWS Cloud where they can launch AWS resources in a virtual network
that they define. Amazon SWF, Amazon Route 53, and AWS CloudFormation do not
provide a virtual network. Amazon SWF helps developers build, run, and scale
background jobs that have parallel or sequential steps. Amazon Route 53 provides a
highly available and scalable cloud Domain Name System (DNS) web service. Amazon
CloudFormation gives developers and systems administrators an easy way to create
and manage a collection of related AWS resources.
, Your company provides a mobile voting application for a popular TV show, and 5 to 25
million viewers all vote in a 15-second timespan. What mechanism can you use to
decouple the voting application from your back-end services that tally the votes?
1. AWS CloudTrail
2. Amazon Simple Queue Service (Amazon SQS)
3. Amazon Redshift
4. Amazon Simple Notification Service (Amazon SNS) - CORRECT ANSWES -- 2
<strong>B.</strong><br>Amazon SQS is a fast, reliable, scalable, fully managed
message queuing service that allows organizations to decouple the components of a
cloud application. With Amazon SQS, organizations can transmit any volume of data, at
any level of throughput, without losing messages or requiring other services to be
always available. AWS CloudTrail records AWS API calls, and Amazon Redshift is a
data warehouse, neither of which would be useful as an architecture component for
decoupling components. Amazon SNS provides a messaging bus complement to
Amazon SQS; however, it doesn't provide the decoupling of components necessary for
this scenario.
