AWS AWS Migration & Hybrid Cloud 5 — Questions and Answers
Question 1: A company running Microsoft SQL Server on-premises wants to migrate to AWS with the least schema and code changes possible. Which target is MOST appropriate?
- Amazon Aurora MySQL
- Amazon RDS for SQL Server (Correct answer)
- Amazon DynamoDB
- Amazon Redshift
Correct answer: Amazon RDS for SQL Server
Amazon RDS for SQL Server provides a fully managed SQL Server environment, minimizing schema and application changes compared to migrating to a different database engine.
Question 2: AWS Direct Connect supports which type of virtual interfaces (VIFs) for connecting to VPCs across multiple AWS accounts?
- Public VIF
- Private VIF
- Transit VIF (Correct answer)
- Hosted VIF
Correct answer: Transit VIF
A Transit VIF connects a Direct Connect connection to an AWS Transit Gateway, enabling connectivity to multiple VPCs and accounts through a single interface.
Question 3: During a migration using AWS DMS, the replication instance runs out of storage. What is the recommended remediation?
- Terminate and recreate the replication instance with more storage
- Modify the replication instance to increase its allocated storage without stopping replication (Correct answer)
- Switch to a Snowball Edge device for the remaining data
- Pause the task and manually clear the replication logs
Correct answer: Modify the replication instance to increase its allocated storage without stopping replication
AWS DMS allows you to modify a replication instance's allocated storage online, and the change takes effect without requiring task interruption in most cases.
Question 4: A company wants to use AWS Outposts to extend AWS infrastructure into its on-premises data center. Which statement about Outposts is TRUE?
- Outposts requires a dedicated internet connection independent of Direct Connect
- Outposts hardware is owned and maintained by the customer
- Outposts delivers AWS compute and storage to on-premises locations and is managed by AWS (Correct answer)
- Outposts only supports Amazon EC2 instances and no managed database services
Correct answer: Outposts delivers AWS compute and storage to on-premises locations and is managed by AWS
AWS Outposts is fully managed by AWS, delivering native AWS services (EC2, EBS, RDS, EKS, etc.) to customer on-premises locations with AWS-owned hardware.
Question 5: Which AWS service helps assess on-premises server utilization and dependency mapping to plan a migration, without requiring agents on every server?
- AWS Migration Hub Orchestrator
- AWS Application Discovery Service with agentless discovery via the Discovery Connector (Correct answer)
- AWS Systems Manager Inventory
- AWS Config with resource relationships
Correct answer: AWS Application Discovery Service with agentless discovery via the Discovery Connector
The AWS Application Discovery Service Discovery Connector is an agentless VMware appliance that collects VM metadata and performance data without installing agents on each server.
Question 6: A company is using AWS Transit Gateway to connect multiple VPCs and an on-premises network via Direct Connect. They want to prevent VPCs from communicating with each other while still allowing all VPCs to reach on-premises. How is this achieved?
- Use separate Transit Gateways for each VPC
- Use Transit Gateway route tables with isolated routing — attach VPCs to an isolated route table that only propagates the on-premises route (Correct answer)
- Use VPC peering between each VPC pair with deny rules
- Enable blackhole routes in each VPC's main route table
Correct answer: Use Transit Gateway route tables with isolated routing — attach VPCs to an isolated route table that only propagates the on-premises route
Transit Gateway supports segmented routing via multiple route tables; placing VPCs in an isolated route table that only has the on-premises prefix prevents VPC-to-VPC traffic while allowing on-premises connectivity.
Question 7: When using AWS Storage Gateway in Tape Gateway mode, where are virtual tape archives stored after they are ejected from the virtual tape library (VTL)?
- Amazon EBS
- Amazon S3 Standard
- Amazon S3 Glacier or Glacier Deep Archive (Correct answer)
- Amazon FSx for Windows
Correct answer: Amazon S3 Glacier or Glacier Deep Archive
Ejected virtual tapes move to Amazon S3 Glacier or Glacier Deep Archive (the virtual tape shelf), providing low-cost, durable long-term storage matching physical tape economics.
