Which AWS service provides a single location to track the progress of application migrations?
- A . AWS Application Discovery Service
- B . AWS Application Migration Service
- C . AWS Service Catalog
- D . AWS Migration Hub
D
Explanation:
AWS Migration Hub is a service that provides a single location to track the progress of application migrations across multiple AWS and partner solutions. It allows you to choose the AWS and partner migration tools that best fit your needs, while providing visibility into the status of migrations across your portfolio of applications1. AWS Migration Hub supports migration status updates from the following tools: AWS Application Migration Service, AWS Database Migration Service, CloudEndure Migration, Server Migration Service, and Migrate for Compute Engine1.
The other options are not correct for the following reasons:
AWS Application Discovery Service is a service that helps you plan your migration projects by automatically identifying servers, applications, and dependencies in your on-premises data centers2. It does not track the progress of application migrations, but rather provides information to help you plan and scope your migrations.
AWS Application Migration Service is a service that helps you migrate and modernize applications from any source infrastructure to AWS with minimal downtime and disruption3. It is one of the migration tools that can send status updates to AWS Migration Hub, but it is not the service that provides a single location to track the progress of application migrations.
AWS Service Catalog is a service that allows you to create and manage catalogs of IT services that are approved for use on AWS4. It does not track the progress of application migrations, but rather helps you manage the provisioning and governance of your IT services:

Which AWS Well-Architected Framework pillar focuses on structured and streamlined allocation of computing resources?
- A . Reliability
- B . Operational excellence
- C . Performance efficiency
- D . Sustainability
C
Explanation:
Understanding Performance Efficiency: This pillar of the AWS Well-Architected Framework focuses on using computing resources efficiently to meet system requirements and maintain that efficiency as demand changes and technologies evolve.
Key Aspects of Performance Efficiency:
Selection: Choose the right resources for the job. This includes using the most appropriate instance types, storage options, and database services.
Review: Regularly review your architecture to take advantage of the latest AWS services and features, and to ensure you’re using the best possible resource for your needs.
Monitoring: Continuously monitor your system performance, gather metrics, and use those metrics to make informed decisions about scaling and performance optimization.
Trade-offs: Understand the trade-offs between various performance-related aspects, such as cost, latency, and durability, and make decisions that align with your business goals.
How to Implement Performance Efficiency:
Use Auto Scaling: Implement Auto Scaling to automatically adjust the number of resources based on the demand.
Choose Appropriate Storage Options: Select the right storage solution (e.g., S3, EBS, or EFS) based on performance and access patterns.
Optimize Networking: Utilize Amazon CloudFront, AWS Global Accelerator, and VPC to optimize your network performance.
Regular Review and Testing: Regularly review your architecture, test performance under various
loads, and adjust configurations as needed:

D
Explanation:
Amazon RDS supports six database engines: Amazon Aurora, MySQL, MariaDB, PostgreSQL, Oracle, and SQL Server. Apache Cassandra, MongoDB, and Neo4j are not compatible with Amazon RDS. Therefore, the correct answer is D. You can learn more about Amazon RDS and its supported database engines
A company plans to migrate to the AWS Cloud. The company wants to gather information about its on-premises data center.
Which AWS service should the company use to meet these requirements?
- A . AWS Application Discovery Service
- B . AWS DataSync
- C . AWS Storage Gateway
- D . AWS Database Migration Service (AWS DMS)
A
Explanation:
AWS Application Discovery Service helps companies gather information about on-premises data centers to support migration planning. It collects data on system configuration, resource utilization, and network dependencies, providing essential insights for migration.

Which AWS Cloud benefit is shown by an architecture’s ability to withstand failures with minimal downtime?
- A . Agility
- B . Elasticity
- C . Scalability
- D . High availability
D
Explanation:
Understanding High Availability: High availability (HA) refers to systems that are durable and likely to operate continuously without failure for a long time. HA ensures that an architecture can withstand failures with minimal downtime.
Importance of High Availability:
Redundancy: Systems are designed with redundancy to prevent single points of failure.
Fault Tolerance: Ensures that failures do not result in significant downtime, maintaining service continuity.
Automated Recovery: Utilizes automated recovery mechanisms to quickly restore services in the event of a failure.
AWS Services for High Availability:
Multi-AZ Deployments: Services like RDS, DynamoDB, and others support Multi-AZ deployments for
fault tolerance.
Elastic Load Balancing: Distributes traffic across multiple instances or availability zones to ensure no single point of failure.
Auto Scaling: Automatically adjusts the number of instances based on demand, ensuring availability even during traffic spikes.

Which AWS services are connectivity services for a VPC? (Select TWO.)
- A . AWS Site-to-Site VPN
- B . AWS Direct Connect
- C . Amazon Connect
- D . AWS Key Management Service (AWS KMS)
- E . AWS Identity and Access Management (IAM)
A
Explanation:
AWS Site-to-Site VPN and AWS Direct Connect are AWS services that are connectivity services for a VPC. AWS Site-to-Site VPN is a service that enables you to securely connect your on-premises network or branch office site to your Amazon Virtual Private Cloud (Amazon VPC). You can establish VPN connections over the internet or over AWS Direct Connect1. AWS Direct Connect is a service that lets you establish a dedicated network connection between your network and one of the AWS Direct Connect locations. Using AWS Direct Connect, you can create a private connection between AWS and your datacenter, office, or colocation environment, which can reduce your network costs,increase bandwidth throughput, and provide a more consistent network experience than internet-based connections2. Amazon Connect is a service that lets you set up and manage a contact center in the cloud, but it does not provide network connectivity between the VPC and your on-premises network. AWS Key Management Service (AWS KMS) is a service that makes it easy for you to create and manage cryptographic keys and control their use across a wide range of AWS services and inyour applications, but it does not provide network connectivity between the VPC and your on-premises network. AWS Identity and Access Management (IAM) is a service that enables you to manage access to AWS services and resources securely, but it does not provide network connectivity between the VPC and your on-premises network.
A company is migrating its data center to AWS. The company needs an AWS Support plan that provides chat access to a cloud sup engineer 24 hours a day, 7 days a week. The company does not require access to infrastructure event management.
What is the MOST cost-effective AWS Support plan that meets these requirements?
- A . AWS Enterprise Support
- B . AWS Business Support
- C . AWS Developer Support
- D . AWS Basic Support
B
Explanation:
AWS Business Support is the most cost-effective AWS Support plan that provides chat access to a cloud support engineer 24/7. AWS Business Support also offers phone and email support, as well as a response time of less than one hour for urgent issues. AWS Business Support does not include access to infrastructure event management, which is a feature of AWS Enterprise Support. AWS Enterprise Support is more expensive and provides additional benefits, such as a technical account manager, a support concierge, and a response time of less than 15 minutes for critical issues. AWS Developer Support and AWS Basic Support do not provide chat access to a cloud support engineer. AWS Developer Support provides email support and a response time of less than 12 hours for general guidance issues. AWS Basic Support provides customer service and account support, as well as access to forums and documentation1
