Q1. A startup is developing a web application where users can find articles based on various criteria such as keywords, authors, or topics. They seek an AWS service that can handle this function efficiently. Which service should they use?
Answer: B. Amazon OpenSearch Service
Amazon OpenSearch Service provides managed search and analytics, ideal for keyword-based lookups across large content sets. EC2 could host a custom search stack but adds management overhead and no built-in search capability.
Q2. A company plans to use reserved instances to get discounted pricing for Amazon EC2 instances. The company may need to change the EC2 instance type during the one year period. Which instance purchasing option is the MOST cost-effective for…
Answer: B. Convertible Reserved Instances
Convertible Reserved Instances can be exchanged for a different instance family, OS, or tenancy during the term. Standard Reserved Instances offer a bigger discount but lock the configuration, so they fail this requirement.
Q3. Which of the following is a sole responsibility of AWS?
Answer: C. Availability Zone management
Under the shared responsibility model, AWS solely manages the global infrastructure, including Availability Zones. Patch management is split depending on the service, and data access controls always belong to the customer.
Q4. A company is planning to deploy an application with a relational database on AWS. The application layer requires access to the database instance's operating system in order to run scripts. The company prefers to keep management overhead to…
Answer: A. Amazon EC2
Only EC2 allows OS-level access, which the scripting requirement demands, even though it means more management work. RDS would minimize overhead but blocks shell access, making it the trap answer here.
Q5. Which type of credential should a Cloud Practitioner use for programmatic access to AWS resources from the AWS CLI/API?
Answer: A. Access keys
Access keys are the long-term credentials used to sign CLI and API requests programmatically. A user name and password only work for console sign-in, so it is the classic distractor.
Q6. Which tasks require the use of the AWS account root user? (Select TWO.)
Answer: B,D. Changing the account name. || Changing AWS Support plans.
Tasks that require the AWS account root user include changing the account name and changing AWS Support plans. A handy exam cue: root user tasks are rare and account-level, while S3 encryption and CloudTrail log viewing can all be delegated to IAM users or roles.
Q7. A company has multiple AWS accounts and is using AWS Organizations with consolidated billing. Which advantages will they benefit from? (Select TWO.)
Answer: A,C. They may benefit from lower unit pricing for aggregated usage. || They will receive one bill for the accounts in the Organization.
Consolidated billing in AWS Organizations provides one bill for all accounts and combines usage so volume discounts, Reserved Instance discounts, and Savings Plans can be shared. The strongest distractor, a fixed discount, fails because discounts come from volume tiers and commitments, not a flat rate.
Q8. Which of the following represents a value proposition for using the AWS Cloud?
Answer: A. It is not necessary to enter into long term contracts.
A core value proposition of AWS is pay-as-you-go pricing with no long-term contracts required, though optional commitments earn discounts. Remember the shared responsibility model: AWS never secures your applications, and customers cannot access data centers or pick hardware.
Q9. A company is planning to move a number of legacy applications to the AWS Cloud. The solution must be cost-effective. Which approach should the company take?
Answer: C. Rehost the applications on Amazon EC2 instances that are right-sized.
For a cost-effective migration of legacy applications, rehosting onto right-sized EC2 instances is the fastest and cheapest approach that works as-is. Dedicated hosts cost more, Lambda requires rearchitecting, and S3 static hosting only serves static content.
Q10. Which of the following are valid benefits of using the AWS Cloud? (Select TWO.)
Answer: C,D. Ability to go global quickly. || Fast provisioning of IT resources.
Going global quickly and provisioning IT resources fast are two of the six advantages of cloud computing. Watch for absolutes in distractors: words like all in outsource all operational risk signal a wrong answer, and customers never control physical data center infrastructure.
Q11. Which of the following can an AWS customer use to launch a new ElastiCache cluster? (Select TWO.)
Answer: C,E. AWS Management Console || AWS CloudFormation
You can launch an ElastiCache cluster through the AWS Management Console or automate it with AWS CloudFormation templates. Exam cue: the console, CLI, SDKs, and CloudFormation are the standard ways to provision resources, while Concierge support only assists Enterprise plan customers.
