Question #1
A company is planning to run a global marketing application in the AWS Cloud. The application will feature videos that can be viewed by users. The company must ensure that all users can view these videos with low latency.
Which AWS service should the company use to meet this requirement?
Which AWS service should the company use to meet this requirement?
- AAWS Auto Scaling
- BAmazon Kinesis Video Streams
- CElastic Load Balancing
- DAmazon CloudFrontMost Voted
Correct Answer:
D
D

Amazon CloudFront is the optimal choice for reducing latency when distributing video content globally. It operates as a content delivery network (CDN), which caches content in various locations worldwide. This proximity to the end user accelerates the delivery of content, ensuring a smoother, faster viewing experience regardless of the viewer's geographical location. Using CloudFront can significantly enhance user satisfaction by minimizing video loading times and buffering delays, crucial for maintaining engagement in a marketing application.

- ASecurity
- BReliabilityMost Voted
- CPerformance efficiency
- DCost optimization
Correct Answer:
B
B

The AWS Well-Architected Framework's reliability pillar precisely aims to ensure that workloads execute their intended functions efficiently and can swiftly recover from system or service disruptions. This involves not just continuity and recovery strategies but also effectively adapting to changing conditions or demands by appropriately scaling computing resources. This element is crucial for maintaining the operational integrity and resilience of applications and services within the AWS environment.

Question #4
A company is planning to replace its physical on-premises compute servers with AWS serverless compute services. The company wants to be able to take advantage of advanced technologies quickly after the migration.
Which pillar of the AWS Well-Architected Framework does this plan represent?
Which pillar of the AWS Well-Architected Framework does this plan represent?
- ASecurity
- BPerformance efficiencyMost Voted
- COperational excellence
- DReliability
Correct Answer:
B
B

Performance efficiency, especially in the context of transitioning from on-premises servers to serverless AWS solutions, directly underscores using computing resources effectively to adapt to changing demands and evolving technologies. This focus not only caters to meeting system requirements efficiently but also ensures that as technology progresses, your infrastructure can swiftly adapt, optimizing performance continually. In this scenario, this is precisely what the company aims to achieve by taking advantage of new capabilities post-migration swiftly, making 'Performance Efficiency' the most applicable pillar of the AWS Well-Architected Framework.

Question #5
A large company has multiple departments. Each department has its own AWS account. Each department has purchased Amazon EC2 Reserved Instances.
Some departments do not use all the Reserved Instances that they purchased, and other departments need more Reserved Instances than they purchased.
The company needs to manage the AWS accounts for all the departments so that the departments can share the Reserved Instances.
Which AWS service or tool should the company use to meet these requirements?

Question #6
Which component of the AWS global infrastructure is made up of one or more discrete data centers that have redundant power, networking, and connectivity?
- AAWS Region
- BAvailability ZoneMost Voted
- CEdge location
- DAWS Outposts
Correct Answer:
B
B

Correct choice! Indeed, an Availability Zone (AZ) in AWS includes one or more distinct data centers located within a region. What sets it apart is its own separate facilities like power backups and networking resources. This kind of infrastructure supports high availability and durability by remaining operational even if there’s an issue in other AZs, thus ensuring uninterrupted service. Also, for the records, AZs are not synonymous with data centers, as each zone can have multiple data centers. This clear distinction helps in setting robust and reliable cloud solutions, promoting fault tolerance within the AWS ecosystem.

Question #7
Which duties are the responsibility of a company that is using AWS Lambda? (Choose two.)
- ASecurity inside of codeMost Voted
- BSelection of CPU resources
- CPatching of operating system
- DWriting and updating of codeMost Voted
- ESecurity of underlying infrastructure
Correct Answer:
AD
AD

AWS Lambda manages the infrastructure's security and maintenance but leaves certain responsibilities to the user, specifically surrounding the code itself. As a cloud user, you are responsible for ensuring your code is secure from vulnerabilities and for its creation and updates. This separation of duties allows developers to focus more on building with efficiency and innovation in mind, rather than the underlying operational details.

Question #8
Which AWS services or features provide disaster recovery solutions for Amazon EC2 instances? (Choose two.)
- A׀•׀¡2 Reserved Instances
- BEC2 Amazon Machine Images (AMIs)Most Voted
- CAmazon Elastic Block Store (Amazon EBS) snapshotsMost Voted
- DAWS Shield
- EAmazon GuardDuty
Correct Answer:
BC
BC

For disaster recovery of Amazon EC2 instances, Amazon Machine Images (AMIs) and Amazon Elastic Block Store (EBS) snapshots are key services. AMIs allow for the creation of a duplicate instance with the same configurations, encompassing both the OS and applications. EBS snapshots provide point-in-time backups of volumes, essential for data recovery or setting up instances in new locations, making these tools indispensable for robust disaster recovery strategies.

Question #9
A company is migrating to the AWS Cloud instead of running its infrastructure on premises.
Which of the following are advantages of this migration? (Choose two.)
Which of the following are advantages of this migration? (Choose two.)
- AElimination of the need to perform security auditing
- BIncreased global reach and agilityMost Voted
- CAbility to deploy globally in minutesMost Voted
- DElimination of the cost of IT staff members
- ERedundancy by default for all compute services
Correct Answer:
BD
BD

Absolutely, when businesses shift to AWS Cloud from an on-prem setup, two vital boosts they get are the capacity for quick global deployment and increased agility. This makes them speedier and more flexible in addressing market changes and customer needs globally. The idea that cloud migration removes IT staff costs isn't really spot on; it mainly decreases capital expenses and shifts spending from heavy upfront investments to more manageable variable costs. Also, the cloud model immensely scales operations without having to guess the infrastructure capacity needed.

Question #10
A user is comparing purchase options for an application that runs on Amazon EC2 and Amazon RDS. The application cannot sustain any interruption. The application experiences a predictable amount of usage, including some seasonal spikes that last only a few weeks at a time. It is not possible to modify the application.
Which purchase option meets these requirements MOST cost-effectively?
Which purchase option meets these requirements MOST cost-effectively?
- AReview the AWS Marketplace and buy Partial Upfront Reserved Instances to cover the predicted and seasonal load.
- BBuy Reserved Instances for the predicted amount of usage throughout the year. Allow any seasonal usage to run on Spot Instances.
- CBuy Reserved Instances for the predicted amount of usage throughout the year. Allow any seasonal usage to run at an On-Demand rate.Most Voted
- DBuy Reserved Instances to cover all potential usage that results from the seasonal usage.
Correct Answer:
B
B

Reserved Instances provide a significant discount compared to On-Demand pricing and are ideal for predictable workloads, making them a suitable choice for the primary, consistent load of the application described. Using Spot Instances for handling seasonal spikes is cost-effective; however, they can be interrupted, which is a risk for applications that cannot sustain interruptions. Given this, although not ideal under strict no-interruption conditions, it can be a viable solution if the spikes are managed carefully to minimize disruption risks. However, option C, using On-Demand for seasonal spikes, whilst more expensive, ensures zero interruptions, aligning better with the application's stringent availability requirements.
