Hello, In this article I will cover up some of the sample questions asked in the AWS Certified Solutions Architect – Associate certification exam. These questions should help you to get understanding of the pattern of the exam and the questions asked.
I have taken these questions from the book named AWS Certified solutions architect official study guide. This is one of the best book to prepare for AWS certified solutions architect associate exam.
I think this book is quite enough to prepare for the exam as it has good number of self paced labs and enough sample question and answers.
Moreover if you are the one who is more interested in learning from videos instead of the books. There is a very good course which can help you to clear the exam with minimum efforts. Here is the link to the exam: AWS certified solutions architect .
You can also read my post on how to prepare for AWS certifications.
1.Which of the following describes a physical location around the world where AWS clusters data centers?
- Endpoint
- Collection
- Fleet
- Region
2.Each AWS region is composed of two or more locations that offer organizations the ability to operate production systems that are more highly available, fault tolerant, and scalable than would be possible using a single data center. What are these locations called?
- Availability Zones
- Replication areas
- Geographic districts
- Compute centers
3.Which AWS Cloud service allows organizations to gain system-wide visibility into resource utilization, application performance, and operational health?
- AWS Identity and Access Management (IAM)
- Amazon Simple Notification Service (Amazon SNS)
- Amazon CloudWatch
- AWS CloudFormation
4. Your company runs an Amazon Elastic Compute Cloud (Amazon EC2) instance periodically to perform a batch processing job on a large and growing filesystem. At the end of the batch job, you shut down the Amazon EC2 instance to save money but need to persist the filesystem on the Amazon EC2 instance from the previous batch runs. What AWS Cloud service can you leverage to meet these requirements?
- Amazon Elastic Block Store (Amazon EBS)
- Amazon DynamoDB
- Amazon Glacier
- AWS CloudFormation

- Data is automatically replicated to other regions.
- Data is automatically replicated within a region.
- Data is replicated only if versioning is enabled on the bucket.

- DELETE after PUT of new object
12.Amazon Glacier is well-suited to data that is which of the following? (Choose 2 answers)
- Is infrequently or rarely accessed
- Must be immediately available when needed
- Is available after a three- to five-hour restore period
- Is frequently erased within 30 days
13.Your web application needs four instances to support steady traffic nearly all of the time. On the last day of each month, the traffic triples. What is a cost-effective way to handle this traffic pattern?
- Run 12 Reserved Instances all of the time.
- Run four On-Demand Instances constantly, then add eight more On-Demand Instances on the last day of each month.
- Run four Reserved Instances constantly, then add eight On-Demand Instances on the last day of each month.
- Run four On-Demand Instances constantly, then add eight Reserved Instances on the last day of each month.
14.Your order-processing application processes orders extracted from a queue with two Reserved Instances processing 10 orders/minute. If an order fails during processing, then it is returned to the queue without penalty. Due to a weekend sale, the queues have several hundred orders backed up. While the backup is not catastrophic, you would like to drain it so that customers get their confirmation emails faster. What is a cost-effective way to drain the queue for orders?
- Create more queues.
- Deploy additional Spot Instances to assist in processing the orders.
- Deploy additional Reserved Instances to assist in processing the orders.
- Deploy additional On-Demand Instances to assist in processing the orders.
15.You have purchased an m3.xlarge Linux Reserved instance in us-east-1a. In which ways can you modify this reservation? (Choose 2 answers)
- Change it into two m3.large instances.
- Change it to a Windows instance.
- Move it to us-east-1b.
- Change it to an m4.xlarge.
Answers:
- D. A region is a named set of AWS resources in the same geographical area. A region comprises at least two Availability Zones. Endpoint, Collection, and Fleet do not describe a physical location around the world where AWS clusters data centers.
- A. An Availability Zone is a distinct location within a region that is insulated from failures in other Availability Zones and provides inexpensive, low-latency network connectivity to other Availability Zones in the same region. Replication areas, geographic districts, and compute centers are not terms used to describe AWS data center locations.
- C. Amazon CloudWatch is a monitoring service for AWS Cloud resources and the applications organizations run on AWS. It allows organizations to collect and track metrics, collect and monitor log files, and set alarms. AWS IAM, Amazon SNS, and AWS CloudFormation do not provide visibility into resource utilization, application performance, and the operational health of your AWS resources.
- A. Amazon EBS provides persistent block-level storage volumes for use with Amazon EC2 instances on the AWS Cloud. Amazon DynamoDB, Amazon Glacier, and AWS CloudFormation do not provide persistent block-level storage for Amazon EC2 instances. Amazon DynamoDB provides managed NoSQL databases. Amazon Glacier provides low-cost archival storage. AWS CloudFormation gives developers and systems administrators an easy way to create and manage a collection of related AWS resources.
- B. Amazon SQS is a fast, reliable, scalable, fully managed message queuing service that allows organizations to decouple the components of a cloud application. With Amazon SQS, organizations can transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be always available. AWS CloudTrail records AWS API calls, and Amazon Redshift is a data warehouse, neither of which would be useful as an architecture component for decoupling components. Amazon SNS provides a messaging bus complement to Amazon SQS; however, it doesn’t provide the decoupling of components necessary for this scenario.
- D, E. Objects are stored in buckets, and objects contain both data and metadata.
- B, D. Amazon S3 cannot be mounted to an Amazon EC2 instance like a file system and should not serve as primary database storage.
- B, C, E. Static website hosting does not restrict data access, and neither does an Amazon S3 lifecycle policy.
- C, E. Versioning protects data against inadvertent or intentional deletion by storing all versions of the object, and MFA Delete requires a one-time code from a Multi-Factor Authentication (MFA) device to delete objects. Cross-region replication and migration to the Amazon Glacier storage class do not protect against deletion. Vault locks are a feature of Amazon Glacier, not a feature of Amazon S3.
- B. Data is automatically replicated within a region. Replication to other regions and versioning are optional. Amazon S3 data is not backed up to tape.
- B, C. Amazon S3 provides read-after-write consistency for PUTs to new objects (new key), but eventual consistency for GETs and DELETEs of existing objects (existing key).
- A, C. Amazon Glacier is optimized for long-term archival storage and is not suited to data that needs immediate access or short-lived data that is erased within 90 days.
- C. Reserved Instances provide cost savings when you can commit to running instances full time, such as to handle the base traffic. On-Demand Instances provide the flexibility to handle traffic spikes, such as on the last day of the month.
- B. Spot Instances are a very cost-effective way to address temporary compute needs that are not urgent and are tolerant of interruption. That’s exactly the workload described here. Reserved Instances are inappropriate for temporary workloads. On-Demand Instances are good for temporary workloads, but don’t offer the cost savings of Spot Instances. Adding more queues is a non-responsive answer as it would not address the problem.
- A, C. You can change the instance type only within the same instance type family, or you can change the Availability Zone. You cannot change the operating system nor the instance type family.
