WEEK 4 QUIZ
FINAL ASSESSMENT

INTRODUCTION

In the final week of this course, you focus on the migrate and modernize phase of the migration structure. During week 4, you learn about migrating specific types of components and the services that assist with their migration: AWS Application Migration Service, AWS Database Migration Service, AWS DataSync, AWS Storage Gateway, and the AWS Snow Family. This week closes with some additional resources so that you can continue your self-paced study with AWS.

Learning Objectives

Learn about the AWS Snow Family
Differentiate between migrating applications and databases

Demonstrate an understanding of AWS Schema Conversion Tool (AWS SCT)

WEEK 4 QUIZ

1. Which of the following is one of the 7Rs of migration?

Replatform (CORRECT)

Reanimate
Reallocate

Correct: The seven common migration strategies (7 Rs) for moving applications to the AWS Cloud are refactor, replatform, repurchase, rehost, relocate, retain, and retire.

2. Which AWS service is used for a one-time migration of a large amount of data?

AWS Direct Connect
AWS Snow Family (CORRECT)
Virtual private network (VPN)

Amazon DynamoDB

Correct: The AWS Snow Family helps physically transport up to exabytes of data into and out of AWS.

3. Which AWS service tracks the overall progression of the migration process?

AWS Control Tower

AWS CloudFormation
AWS Migration Hub (CORRECT)
AWS Database Migration Service (AWS DMS)

Correct: AWS Migration Hub is the one destination for cloud migration and modernization, giving you the tools you need to accelerate and simplify your journey with AWS.

4. Which service creates standardized application templates that can be deployed by the end user?

AWS Systems Manager
AWS Service Catalog (CORRECT)

Amazon CloudFront
AWS Migration Hub

Correct: AWS Service Catalog helps you create and manage infrastructure as code (IaC) templates that are approved for use on AWS. With AWS Service Catalog, anyone can discover approved, self-service cloud resources.

5. What is one benefit of using AWS Database Migration Service (AWS DMS)?

AWS DMS only supports migrating MySQL databases
AWS DMS only supports homogeneous migrations
AWS DMS allows the source database to remain fully operational during migration. (CORRECT)

AWS DMS does not support heterogeneous migrations.

Correct: AWS DMS helps migrate databases to AWS quickly and securely. The source database remains fully operational during the migration, minimizing downtime to applications that rely on the database.

FINAL ASSESSMENT

1. What is an example of rehosting an application?

Before moving an application to the cloud, the application is rewritten in a new programing language.

During a migration, older applications are discovered. They are no longer needed and can be turned off.
A containerized application can be moved from on premises to the cloud without making any changes.
All on-premises applications and resources can be easily moved to the cloud except for the load balancers. The existing load balancers are replaced by Elastic Load Balancing (ELB) load balancers. (CORRECT)

Correct: With rehosting (also known as lift and shift), applications are moved to the cloud without making any changes to take advantage of cloud capabilities.

2. Which of the following are steps in creating a migration plan? [Choose TWO.]

Creating a reverse migration plan back to the data center
Creating the shortest possible migration timeline to encourage a faster migration

Increasing on-premises capacity through hardware acquisition
Determining service migration path (CORRECT)
Communicating your plan to coworkers

Creating a reverse migration plan back to the data center
Creating the shortest possible migration timeline to encourage a faster migration
Increasing on-premises capacity through hardware acquisition

Determining service migration path (CORRECT)
Communicating your plan to coworkers (CORRECT)

Correct: In the early stages of migration planning, it is important to determine the service migration path by assessing the on-premises resources you have, and deciding which of these resources will be migrated to the cloud.

Correct: It is also important to communicate the migration plan to all stakeholders because successful migrations require significant contributions from many different parts of the business.

3. Which statement about the AWS shared responsibility security model is TRUE?

AWS is responsible for security of the cloud, and the customer is responsible for security in the cloud. (CORRECT)
Security is a responsibility fully shared between the AWS Partners and the customer.

Security is entirely the responsibility of AWS, and is verified by auditors.
Security is the shared responsibility of the customer and their chosen third-party security providers.

Correct: AWS is responsible for protecting the infrastructure that runs all the services that are offered in the AWS Cloud. Customers are responsible for protecting their data, securing networks and firewalls, performing identity and access management, and (depending on the service) managing operating systems and applications. For more information, see Shared Responsibility Model (https://aws.amazon.com/compliance/shared-responsibility-model/).

4. What does AWS Prescriptive Guidance provide to customers?

A fully automated migration tool
Strategies, methodologies, and frameworks for cloud migration and modernization (CORRECT)
Direct access to the AWS Migration team

A single location to inventory assets and track migration of applications

Correct: AWS Prescriptive Guidance provides time-tested strategies, guides, and patterns to help accelerate the customer’s cloud migration, modernization, and optimization projects.

5. Which of the following is a stage in the assessing process?

Rebuild

Foundation (CORRECT)
Re-evaluation
Mitigation

Correct: When organizations contemplate large-scale migration to AWS, they generally fall somewhere along the path of what is called the stages of adoption, which has four stages: project, foundation, migration, and reinvention.

6. Which AWS Migration Evaluator tool is designed to provide visibility into inventory and resource utilization data with a high level of accuracy?

Mobilization assessment
Inventory discovery (CORRECT)

Content evaluation
Application discovery

Correct: Migration Evaluator offers an agentless collector that can help with collecting information about existing inventory and resource utilization data. For more information, see Migration Evaluator resources (https://aws.amazon.com/migration-evaluator/resources/).

7. What does AWS Migration Hub provide?

A single place to track migrations (CORRECT)
A single place to build AWS CloudFormation templates
A bucket for AWS CloudTrail logs

A single place to manage Amazon CloudWatch metrics

Correct: AWS Migration Hub (Migration Hub) provides a single place to discover existing servers, plan migrations, and track the status of each application migration.

8. What is a requirement for doing an agentless installation of the AWS Application Discovery Service Agent?

Using VMware vCenter (CORRECT)

Using Lambda functions
Using serverless servers on premises
Using Amazon Elastic Compute Cloud (Amazon EC2) instances

Correct: The AWS Agentless Discovery Connector (Discovery Connector) is a VMware appliance that can collect information only about VMware virtual machines (VMs). You install the Discovery Connector as a VM in your VMware vCenter Server environment by using an Open Virtualization Archive (OVA) file.

9. Which networking service transfers large, ongoing amounts of data between a customer’s data center and the cloud?

AWS Direct Connect (CORRECT)
AWS Snowmobile

Virtual private network (VPN)
