Q1. Which of the below is an example of an architectural benefit of moving to the cloud?
Answer: C. Elasticity
Elasticity is the hallmark cloud architectural benefit, scaling resources up and down automatically with demand. Vertical scalability exists on-premises too, so it is not a distinguishing benefit of the cloud.
Q2. An ecommerce company is using Auto Scaling groups to manage a group of web servers running on Amazon EC2 and are additionally placed behind an Elastic Load balancer. This architecture follows which AWS Well-Architected Framework best pract…
Answer: B. Design for failure
Auto Scaling with health check replacement plus a load balancer is the classic example of designing for failure and expecting components to fail. Decoupling is done with queues or messaging services like SQS, not load balancers.
Q3. A company has 50 different business units and requires that each business unit's billing information is viewed separately. What should a cloud practitioner recommend?
Answer: B. Tag each business unit's resources, then filter by unit in Cost Explorer.
Cost allocation tags let you break down spend by business unit and filter those tags in Cost Explorer. Splitting by Region or VPC is unnecessary, and the coverage report is a Savings Plans feature, not a general billing view.
Q4. Which AWS services are associated with Edge Locations? (Select TWO.)
Answer: D,E. Amazon CloudFront || AWS Shield
CloudFront edge locations cache content close to users, and AWS Shield runs at the edge to absorb DDoS attacks. Direct Connect is a private physical connection into AWS, so it is not tied to edge locations.
Q5. A company has a mission critical Linux-based application. The application must run every Monday from 6 AM until 10pm. As the application is critical, it cannot be interrupted. Which Amazon EC2 instance purchasing option meets these require…
Answer: C. On-Demand Capacity Reservation with Savings Plan
On-Demand Capacity Reservations with a Savings Plan guarantee capacity in a specific Availability Zone while lowering cost for the predictable Monday schedule. Spot Instances are cheapest but can be interrupted with two minutes' notice, which fails the mission-critical requirement.
Q6. A company plans to connect their on-premises data center to the AWS Cloud and requires consistent bandwidth and performance. Which AWS service should the company choose?
Answer: C. AWS Direct Connect
AWS Direct Connect provides a dedicated private connection with consistent bandwidth and performance between on-premises and AWS. Site-to-Site VPN is the common distractor, but it runs over the public internet, so performance varies.
Q7. An IT company has deployed its infrastructure on the AWS cloud. There must be a database that supports reads with a latency of under a millisecond for critical applications. Which AWS service will meet this requirement?
Answer: B. Amazon ElastiCache
Amazon ElastiCache is an in-memory data store delivering sub-millisecond read latency, ideal for caching in front of critical applications. Amazon RDS is a solid database but cannot guarantee single-millisecond response times.
Q8. A company requires a single service which can manage their backup and restore requirements, their data lakes, and archives all in one place. Which AWS service is suitable for all these use cases?
Answer: B. Amazon Simple Storage Service (Amazon S3).
Amazon S3 object storage covers backup and restore, data lakes, and archival use cases in a single service with lifecycle policies. EFS and EBS are the usual distractors, but they serve file and block storage workloads respectively.
Q9. A company needs to optimize costs and resource usage through monitoring of operational health for all resources running on AWS. Which AWS service will meet these requirements?
Answer: D. Amazon CloudWatch
Amazon CloudWatch collects metrics and alarms to monitor operational health and support right-sizing for cost optimization. AWS CloudTrail records API audit events, not real-time performance or health metrics.
Q10. A company has many different business units all using the same AWS services to manage their different applications. Which AWS service or tool can the company use to receive volume discounts across multiple AWS accounts?
Answer: C. AWS Organizations
AWS Organizations enables consolidated billing, so combined usage across accounts reaches volume discount tiers faster. Cost Explorer and AWS Budgets only report and alert on spend, never apply discounts.
