Question 1 of 10
1. Question
A company wants to develop an application that requires sending, storing, and receiving messages across its components in a first-in, first-out (FIFO) delivery process. Which AWS service should be used?
-
-
-
-
Correct
Amazon SQS – Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message-oriented middleware and empowers developers to focus on differentiating work. Importantly, Amazon SQS offers two types of message queues: Standard and FIFO. FIFO queues have the exact ordering of messages and ensure that exactly-once processing is there, thus serving the company‘s requirements in the best possible way.
Incorrect Options:
AWS Step Functions – AWS Step Functions is a serverless workflow service that allows you to coordinate AWS services into serverless workflows. it‘s excellent for managing dependencies and ordering between steps in a workflow, it doesn‘t inherently provide FIFO messaging capabilities.
AWS Glue – AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy to prepare and load your data for analytics. It‘s used for data cataloging and data preparation, but not for messaging or queuing tasks.
Amazon Kinesis Data Streams – Amazon Kinesis Data Streams (KDS) is a massively scalable and durable real-time data streaming service. It can continuously capture gigabytes of data per second from hundreds of thousands of sources. It is used for collecting and processing large streams of data records in real time, but it doesn‘t offer the strict FIFO capabilities like Amazon SQS FIFO queues.

Question 2 of 10
2. Question
A company wants to transfer its existing messaging functionality from an on-premises application to the AWS Cloud. Which of the following AWS services would be used for message broker service?
-
-
-
-
Correct
Amazon MQ – Amazon MQ is a managed message broker service for Apache ActiveMQ. It makes it easy to set up and operate message brokers in the cloud. With Amazon MQ, you can use industry-standard APIs and protocols for messaging, including JMS, NMS, AMQP, STOMP, MQTT, and WebSocket. Message brokers allow different software systems to communicate and exchange information, often enabling real-time integration.
Amazon MQ manages the administration and maintenance tasks of the active-active message broker, including responsibility for broker setup, patching, failure detection, recovery, and message durability. It supports both single-instance brokers for development and testing and active/standby brokers for production workloads. As a fully managed service, Amazon MQ takes care of the heavy lifting involved in the setup, operation, and scaling of a message broker.
Incorrect Options:
Amazon SNS – Amazon Simple Notification Service (SNS) is a fully managed messaging service for both application-to-application and application-to-person communication. Amazon SNS is a powerful service for pub/sub messaging and mobile notifications and it is not a message broker service like Amazon MQ.
Amazon EC2 – Amazon Elastic Compute Cloud (EC2) provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. While you could theoretically set up your own message broker on an EC2 instance, it wouldn‘t offer the same level of managed service that Amazon MQ provides.
AWS Lambda – AWS Lambda lets you run your code without provisioning or managing servers. You pay only for the compute time you consume. Although AWS Lambda can respond to events (including message notifications) and integrate with various AWS messaging services, it is not a message broker service.

Question 3 of 10
3. Question
A company is planning to run a new application on an Amazon EC2 instance. They have limited funds and are very concerned about overspending. So they want to receive an alert when the monthly bill exceeds $500.
As a cloud practitioner, which of the following options do you recommend for this use case? (Select TWO.)
-
-
-
-
-
Correct
Configure AWS Budgets to receive an alert when the threshold is exceeded – AWS Budgets enables you to set custom cost and usage budgets. It allows you to get alerts (via email or Amazon SNS) when your AWS usage or costs exceed the thresholds you‘ve set, like the monthly limit of $500 in our case. These alerts can help to manage costs and reduce the risk of unexpected charges.
Configure Amazon CloudWatch to trigger billing alerts when the threshold is exceeded – Amazon CloudWatch allows you to monitor your AWS resources and applications in real-time. One of its features is the ability to create billing alarms, which can send an alert when your AWS usage costs exceed a specified threshold. By configuring CloudWatch, the company will be alerted if their spending exceeds the set limit.
Incorrect Options:
Configure the Amazon SES to get an email when the threshold is exceeded – Amazon Simple Email Service (SES) is an email platform that provides an easy, cost-effective way for you to send and receive email using your own email addresses and domains. While it can be used to send email alerts triggered by other AWS services, but it does not have built-in functionality to monitor AWS costs or usage.
Configure the Amazon EC2 instance to receive an alert when the threshold is exceeded – Amazon EC2 provides secure, resizable compute capacity in the cloud. It does not have a built-in feature to monitor costs or usage across AWS services. Billing and usage monitoring is not part of the EC2 service.
Configure the AWS Cost Explorer to get an alert when the threshold is exceeded – AWS Cost Explorer is a user interface that lets you visualize, understand, and manage your AWS costs and usage over time. It can provide a detailed view of your past, present, and forecasted AWS usage and costs but it does not have the functionality to send alerts when costs or usage exceed a specified threshold.

Question 9 of 10
9. Question
A movie-based application has some older media files that will be accessed less frequently. Which storage class should be used for cost-effectiveness with high durability and low latency?
-
-
-
-
Correct
S3 Standard-IA – Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is an Amazon S3 storage class for data that is accessed less frequently but requires rapid access when needed. S3 Standard-IA offers the high durability, throughput, and low latency of S3 Standard, with a low per GB storage price and per GB retrieval fee. This combination makes S3 Standard-IA suitable for long-term storage, backups, and as a data store for disaster recovery files. Therefore, for older media files that won‘t be accessed frequently but still need to be readily available when accessed, S3 Standard-IA is an excellent, cost-effective choice.
Incorrect Options:
S3 Standard – Amazon S3 Standard offers high durability, availability, and performance object storage for frequently accessed data, it has a higher cost compared to S3 Standard-IA. It‘s not the most cost-effective choice for data that is accessed less frequently, like the older media files in this case.
S3 Glacier Deep Archive – S3 Glacier Deep Archive is Amazon S3‘s lowest-cost storage class and supports long-term retention and digital preservation for data that may be accessed once or twice in a year. Because of the long retrieval times (up to 12 hours), it‘s not ideal for the given use case, which requires low latency.
S3 One Zone-IA – S3 One Zone-Infrequent Access stores data in a single availability zone, making it less resilient to data loss due to zone failures. It‘s a lower-cost option for infrequently accessed data, it doesn‘t offer the same level of durability as S3 Standard-IA, making it a less optimal choice for the media files in question.

Question 10 of 10
10. Question
Why is an Amazon EC2 instance more beneficial than an on-premises data center for running applications? (Select TWO.)
-
-
-
-
-
Correct
Instances can be launched on-demand when needed – One of the major benefits of using Amazon EC2 (Elastic Compute Cloud) over an on-premises data center is the ability to launch instances on-demand when needed. This allows you to quickly scale capacity, both up and down, as your computing requirements change. You pay only for the compute capacity you consume, making it a cost-effective solution for unpredictable workloads or new applications.
Amazon EC2 allows for scalability in capacity – Amazon EC2 also allows for scalability in capacity. EC2 provides a true virtual computing environment, which means it gives you complete control of your computing resources. You can increase or decrease capacity within minutes, not hours or days. You can also commission one or thousands of server instances simultaneously.
Incorrect Options:
Amazon EC2 costs are billed on a monthly basis – You do receive a monthly bill for Amazon EC2 usage, the benefit here is that you only pay for the resources you use, which can be less expensive than maintaining a fixed-capacity on-premises data center.
Get full administrative control of Amazon EC2 instances – You do have administrative access to your EC2 instances, this is not a unique benefit over an on-premises data center where you would also typically have full administrative control of your servers.
Amazon EC2 provides higher security – AWS provides a number of powerful security measures for EC2, such as security groups and VPCs, saying that EC2 provides higher security than on-premises data centers might not be entirely accurate. The security of an EC2 instance or an on-premises data center can largely depend on how it‘s set up and managed. However, AWS does adhere to many compliance programs which could be beneficial from a security standpoint.

Question 1 of 10
1. Question
A company wants to develop an application that requires sending, storing, and receiving messages across its components in a first-in, first-out (FIFO) delivery process. Which AWS service should be used?
Correct
Amazon SQS – Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message-oriented middleware and empowers developers to focus on differentiating work. Importantly, Amazon SQS offers two types of message queues: Standard and FIFO. FIFO queues have the exact ordering of messages and ensure that exactly-once processing is there, thus serving the company‘s requirements in the best possible way.
Incorrect Options:
AWS Step Functions – AWS Step Functions is a serverless workflow service that allows you to coordinate AWS services into serverless workflows. it‘s excellent for managing dependencies and ordering between steps in a workflow, it doesn‘t inherently provide FIFO messaging capabilities.
AWS Glue – AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy to prepare and load your data for analytics. It‘s used for data cataloging and data preparation, but not for messaging or queuing tasks.
Amazon Kinesis Data Streams – Amazon Kinesis Data Streams (KDS) is a massively scalable and durable real-time data streaming service. It can continuously capture gigabytes of data per second from hundreds of thousands of sources. It is used for collecting and processing large streams of data records in real time, but it doesn‘t offer the strict FIFO capabilities like Amazon SQS FIFO queues.

Question 2 of 10
2. Question
A company wants to transfer its existing messaging functionality from an on-premises application to the AWS Cloud. Which of the following AWS services would be used for message broker service?
Correct
Amazon MQ – Amazon MQ is a managed message broker service for Apache ActiveMQ. It makes it easy to set up and operate message brokers in the cloud. With Amazon MQ, you can use industry-standard APIs and protocols for messaging, including JMS, NMS, AMQP, STOMP, MQTT, and WebSocket. Message brokers allow different software systems to communicate and exchange information, often enabling real-time integration.
Amazon MQ manages the administration and maintenance tasks of the active-active message broker, including responsibility for broker setup, patching, failure detection, recovery, and message durability. It supports both single-instance brokers for development and testing and active/standby brokers for production workloads. As a fully managed service, Amazon MQ takes care of the heavy lifting involved in the setup, operation, and scaling of a message broker.
Incorrect Options:
Amazon SNS – Amazon Simple Notification Service (SNS) is a fully managed messaging service for both application-to-application and application-to-person communication. Amazon SNS is a powerful service for pub/sub messaging and mobile notifications and it is not a message broker service like Amazon MQ.
Amazon EC2 – Amazon Elastic Compute Cloud (EC2) provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. While you could theoretically set up your own message broker on an EC2 instance, it wouldn‘t offer the same level of managed service that Amazon MQ provides.
AWS Lambda – AWS Lambda lets you run your code without provisioning or managing servers. You pay only for the compute time you consume. Although AWS Lambda can respond to events (including message notifications) and integrate with various AWS messaging services, it is not a message broker service.

S3 Standard – Amazon S3 Standard offers high durability, availability, and performance object storage for frequently accessed data, it has a higher cost compared to S3 Standard-IA. It‘s not the most cost-effective choice for data that is accessed less frequently, like the older media files in this case.
S3 Glacier Deep Archive – S3 Glacier Deep Archive is Amazon S3‘s lowest-cost storage class and supports long-term retention and digital preservation for data that may be accessed once or twice in a year. Because of the long retrieval times (up to 12 hours), it‘s not ideal for the given use case, which requires low latency.
S3 One Zone-IA – S3 One Zone-Infrequent Access stores data in a single availability zone, making it less resilient to data loss due to zone failures. It‘s a lower-cost option for infrequently accessed data, it doesn‘t offer the same level of durability as S3 Standard-IA, making it a less optimal choice for the media files in question.

S3 Standard-IA – Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is an Amazon S3 storage class for data that is accessed less frequently but requires rapid access when needed. S3 Standard-IA offers the high durability, throughput, and low latency of S3 Standard, with a low per GB storage price and per GB retrieval fee. This combination makes S3 Standard-IA suitable for long-term storage, backups, and as a data store for disaster recovery files. Therefore, for older media files that won‘t be accessed frequently but still need to be readily available when accessed, S3 Standard-IA is an excellent, cost-effective choice.

Question 10 of 10
10. Question
Why is an Amazon EC2 instance more beneficial than an on-premises data center for running applications? (Select TWO.)
Correct
Instances can be launched on-demand when needed – One of the major benefits of using Amazon EC2 (Elastic Compute Cloud) over an on-premises data center is the ability to launch instances on-demand when needed. This allows you to quickly scale capacity, both up and down, as your computing requirements change. You pay only for the compute capacity you consume, making it a cost-effective solution for unpredictable workloads or new applications.
Amazon EC2 allows for scalability in capacity – Amazon EC2 also allows for scalability in capacity. EC2 provides a true virtual computing environment, which means it gives you complete control of your computing resources. You can increase or decrease capacity within minutes, not hours or days. You can also commission one or thousands of server instances simultaneously.
Incorrect Options:
Amazon EC2 costs are billed on a monthly basis – You do receive a monthly bill for Amazon EC2 usage, the benefit here is that you only pay for the resources you use, which can be less expensive than maintaining a fixed-capacity on-premises data center.
Get full administrative control of Amazon EC2 instances – You do have administrative access to your EC2 instances, this is not a unique benefit over an on-premises data center where you would also typically have full administrative control of your servers.
Amazon EC2 provides higher security – AWS provides a number of powerful security measures for EC2, such as security groups and VPCs, saying that EC2 provides higher security than on-premises data centers might not be entirely accurate. The security of an EC2 instance or an on-premises data center can largely depend on how it‘s set up and managed. However, AWS does adhere to many compliance programs which could be beneficial from a security standpoint.

Be sure to read through all answer explanations thoroughly (even the wrong answers).

Was directed to these exams by my colleague the 3 day before my exam. I immediately purchased and started taking the exams, and can honestly say I would not have passed the exam without doing so.

Review for AWS Certified Cloud Practitioner Exam Questions 2022
★ ★ ★ ★ ★
A V –
I passed the exam today with the help of this mock exams. The questions were not the same but the concepts will surely help to clear the exam. Most important please read the explanation for the questions after every exam.
Bogdan Furtuna –
I passed today the AWS Cloud Practitioner exam.
Skillcertpro tests helped me understand many aspects of this domain.
The explanations are gold and most of all, they are CORRECT.
Allow 3-4 ours / day for 1 test and complete them all.
I guarantee you that at the end you will understand very well many things and all blanks will be filled.
I believe this resource is better than any course or online training as it’s putting ou in front of a test and you test your knowledge. If you are right, that’s good, but if you are wrong, you receive explanations.
Vikram Ayodhya –
I just took the exam yesterday and passed with 95%. Never expected such a big score.. all thanks to your practice questions
Esther mathewe –
There are some spelling errors in few questions.. but overall satisfied with the practice set.. passed my exam

Mani JV –
Thanks skillcertpro for the excellent practice questions, this helped me exam and most importantly it helped me to tackle real exam and mentally prepare myself to sit for a long stretch of 3 hours and at the end your reference to why the answered options were wrong helped me gain more in-depth knowledge. Again thanks for this course.
tony curtis –
Wish I would have found SkillCertPro 1st!!! Would have saved me many many hours. I prep’ed with WizLabs, but feel like i would have flunked had i not heard about SkillCertPro on a AWS CCP exam blog comparing them against all the rest. Passed 1st time with 891. Highly recommend.
Paul David Gelario –

Dalbir Singh –
Passed the exam with 955. These practice questions are very close to the actual exam, highly recommended. When I took the practice tests for the first time, my result was 60% on average. I have read all the explanations of the review section and 3 days later, took all the practice tests again. This time, I scored more than 86% on average. The main exam had 6-7 very hard/confusing questions. Doesn’t bother me much. Thanks a lot skillcertpro team.

I passed the test on the first attempt. I studied for only two weeks with a blank mind and passed it. The question was not the same but just did these practice exams until you got upper 90% scores and read the explanation for the questions after every exam. You could gain good preparation and pass the real exam within a short time. Highly recommended!

Diego Thomaz –
Super good. I passed the exam on the first try. It’s super easy, you just need to do all the practice exams at least once, then you should be good to go if you passed on all of them, or most of them (consider 47/65 as a rule of thumb of what passing means).
Oche Ejembi –
Am I glad I purchased this less than 24 hours to my exam!
I had studied videos and read countless whitepapers – but nothing prepped me for the exam quite like these practice questions. The questions will not appear word for word – but the concepts covered here are more than enough to get you a pass mark

I took 2 free AWS training courses. They were helpful to understand but not as much as these tests are. I studied for 2 weeks with these practice tests. Followed all recommended readings. Repeated the tests until I was above 80%. I passed my test on Feb 27th. I am going to buy The AWS Certified Solutions Architect – Associate examination today and start preparing because I want to keep the momentum. Thank you very much SkillCertPro!
Kevin sunny –
Perfect material for clearing the exam.. kudos to skillcertpro
Ranjana Upadhyay –
I cleared my AWS Certified Cloud Practitioner exam on 2nd August with a score of 934/1000.I was studying the exam course through AWS White papers which to be honest was taking away my interest for this exam.I was recommended by my friend to try this course.So I bought this course and gave multiple times each test till I got a score of 98-100%.
This course is seriously worth each penny I spent.Most of the questions came from this course. Also, just a tip make sure you read the incorrect answers as well with the explanation. Also keep practicing till you get 98-100% score. This course will definitely help you in clearing this certification.
Highly recommended!!!
Sameer Qaiser –
I got 90% of the questions from this course only. I scored 880 in the first attempt itself. Thanks, Skillcertpro for this wonderful content and explanation of questions which helped me a lot in starting my Cloud career.

I passed the exam with these questions. I found quite a lot of them in the exam itself, maybe not word by word by the main idea was the same. I loved the feedback that you get when you answer a question incorrectly, it is very easy to understand it.
Shravya Narayan Sarma –
Totally worth it !
Vinodhini Mohan –
