Question 1:
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?
A. AWS Glue
B. Amazon Kinesis Data Streams
C. AWS Step Functions
D. Amazon SQS
Answer: D
Explanation:
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:
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.)
A. Configure the Amazon SES to get an email when the threshold is exceeded.
B. Configure the Amazon EC2 instance to receive an alert when the threshold is exceeded.
C. Configure Amazon CloudWatch to trigger billing alerts when the threshold is exceeded.
D. Configure AWS Budgets to receive an alert when the threshold is exceeded.
E. Configure the AWS Cost Explorer to get an alert when the threshold is exceeded.
Answer: C and D
Explanation:
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 3:
A company wants to migrate its servers to the AWS cloud. Due to strict compliance regulations, they must have separate hardware in the AWS cloud. They cannot share hardware with other AWS customers. Which of the following server meets this requirement?
A.On-Demand Instances
B. Reserved Instances
C. Dedicated Instances
D. Dedicated Hosts
Answer: D
Explanation:
Dedicated Hosts – Dedicated Hosts provide a physical server that is fully dedicated to your own use. This allows you to have complete control over the physical server and the placement of your instances on the server. This is the only type of instance that allows you to use your own server-bound software licenses. Due to these characteristics, Dedicated Hosts are ideal for workloads that need to meet strict compliance and regulatory requirements. In other words, if your company requires complete isolation at the hardware level, AWS Dedicated Hosts are the way to go.
Incorrect Options:
Reserved Instances – Reserved Instances provide you with a significant discount (up to 75%) compared to On-Demand instance pricing. However, Reserved Instances do not provide physical isolation as they may be deployed on shared hardware.
Dedicated Instances – Dedicated Instances are launched in a VPC on hardware that‘s dedicated to a single customer, they don‘t provide the ability to control or manage the physical server or place instances on a specific physical server like Dedicated Hosts. This is a key differentiator between Dedicated Instances and Dedicated Hosts.
On-Demand Instances – On-Demand Instances let you pay for compute capacity by the hour or second with no long-term commitments. However, they don‘t provide physical isolation at the hardware level because they‘re deployed on shared hardware.

Question 4:
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?
A. S3 Standard
B. S3 One Zone-IA
C. S3 Standard-IA
D. S3 Glacier Deep Archive
Answer: C
Explanation:
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 5:
Why is an Amazon EC2 instance more beneficial than an on-premises data center for running applications? (Select TWO.)
A. Amazon EC2 costs are billed on a monthly basis.
B. Amazon EC2 allows for scalability in capacity.
C. Amazon EC2 provides higher security.
D. Instances can be launched on-demand when needed.
E. Get full administrative control of Amazon EC2 instances.
Answer: B and D
Explanation:
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 6:
Which of the following pairs of benefits of AWS cloud allow organizations to deploy their applications closer to their end-users?
A. Global reach and economy of scale
B. Elasticity and agility
C. High availability and reliability
D. Security and pay-as-you-go pricing
E. Scalability and global reach
Answer: A
Explanation:
Global reach – The benefit of global reach in AWS Cloud refers to its worldwide network of regions and availability zones. This global network allows organizations to deploy their applications closer to their end users, ensuring lower latency and better customer experience. By deploying applications across different geographical regions, businesses can cater to their customers‘ needs more effectively, irrespective of where they are located.
Economy of Scale – Economy of scale is an essential benefit that allows AWS to provide services at a lower cost due to the scale of their operations. It can impact the decision to deploy closer to end users because, with economies of scale, the cost to operate in multiple regions (closer to end-users) becomes feasible.
Incorrect Options:
High Availability and Reliability – High availability and reliability are benefits of AWS Cloud, they primarily pertain to the uptime of services and the ability to recover from failures, rather than the geographical distribution of applications.
Elasticity and Agility – Elasticity and agility refer to the ability to quickly scale resources up or down as per demand, and the speed and flexibility with which organizations can experiment and innovate. These do not contribute to deploying applications closer to end users.
Scalability and Global Reach – Global reach is relevant to deploying applications closer to end users, scalability primarily pertains to the ability to quickly increase or decrease resources as per demand, and not specifically to geographical distribution of applications.
Security and Pay-as-you-go Pricing – Security refers to the various measures AWS provides to keep data and applications safe. Pay-as-you-go pricing is a flexible pricing model that allows businesses to pay only for the resources they use. Neither of these benefits directly facilitates deploying applications closer to end users.

Question 7:
Which of the following services offer the Reserved Instance type when you make a purchase? (Select TWO.)
A. Amazon S3
B. Amazon ECS
C. Amazon SQS
D. AWS Lambda
E. Amazon EC2
Answer: B and E
Explanation:
Amazon EC2 – Amazon EC2 (Elastic Compute Cloud) does indeed offer Reserved Instances. With Reserved Instances, you commit to using a specific instance type over a longer period (one or three years), in return for a significant discount compared to On-Demand Instance pricing. Reserved Instances can provide a capacity reservation, offering a significant discount compared to on-demand pricing, and can significantly reduce costs on a per-instance basis.
Amazon ECS – Amazon ECS (Elastic Container Service) indirectly offers Reserved Instances as it runs on Amazon EC2 instances. You can run your ECS services on a cluster of EC2 instances purchased as Reserved Instances. So, in that way, you could consider ECS to be able to use Reserved Instances.
Incorrect Options:
Amazon S3 – Amazon S3 (Simple Storage Service) is a storage service and doesn‘t offer Reserved Instances. Billing for Amazon S3 is based on your usage of data storage, requests (like GET and PUT), and data transfer.
Amazon SQS – Amazon SQS (Simple Queue Service) is a messaging queue service and doesn‘t offer Reserved Instances. Pricing for SQS is based on the number of requests made to your queue and the amount of data transferred.
AWS Lambda – AWS Lambda is a serverless computing service, and its pricing model doesn‘t involve instances, so it doesn‘t offer Reserved Instances. With Lambda, you‘re charged for the compute time you consume and the number of requests.

Question 8:
Which of the following are the advantages of using AWS Organizations? (Select TWO.)
A. Can take advantage of quantity discounts with a single bill.
B. Will get a higher discount for EC2 instances reservation from the regular price.
C. Will receive a fixed discount for usage across accounts.
D. Can use a single enterprise support plan for all accounts.
E. Can share critical resources with other accounts in the Organization.
Answer: A and E
Explanation:
Can take advantage of quantity discounts with a single bill – AWS Organizations allows you to centrally manage and govern multiple AWS accounts. One of the advantages of AWS Organizations is the ability to consolidate billing across multiple AWS accounts. This means that usage across all accounts is consolidated into a single bill. The advantage here is that by aggregating usage from all accounts, you can reach higher usage tiers and potentially unlock quantity-based discounts, which could lead to cost savings.
Can share critical resources with other accounts in the Organization – AWS Organizations allows you to share resources across accounts. This can include sharing of Amazon Machine Images (AMIs), snapshots, and even AWS Reserved Instances. It makes resource management easier and more efficient. This sharing capability also enables collaborative development environments, helping to improve efficiency and productivity. You can apply policies for shared resources at the organization level, thus reducing the management overhead of handling each account individually.
Incorrect Options:
Will receive a fixed discount for usage across accounts – AWS does not offer fixed discounts for usage across multiple accounts in an AWS Organization. Any potential cost savings come from volume-based discounts as usage across all accounts is aggregated.
Can use a single enterprise support plan for all accounts – AWS enterprise support plan is not shared across all the accounts in an organization. Each account would need to have its own support plan.
Will get a higher discount for EC2 instances reservation from the regular price – Using Reserved Instances can lead to cost savings compared to On-Demand Instance pricing, there‘s no specific extra discount for EC2 instances reservation for AWS Organizations beyond what is normally offered by AWS.

Question 9:
According to the shared responsibility model, which operational controls does a customer fully inherit from AWS? (Select TWO.)
A. Configuration management controls
B. Environmental controls
C. Patch management controls
D. Awareness & Training controls
E. Physical controls
Answer: B and E
Explanation:
Physical Controls – In the AWS shared responsibility model, AWS is responsible for the security ‘of‘ the cloud, while the customer is responsible for security ‘in‘ the cloud. Physical controls, which involve the physical security of data centers and infrastructure, fall under AWS‘s responsibility. This includes the physical security of the buildings, servers, networking hardware, and other physical assets used to provide AWS services. As such, customers effectively inherit these controls from AWS.
Environmental Controls – Environmental controls, which include factors such as HVAC systems, power supply systems, fire prevention and suppression, and others that maintain a secure and stable environment for the infrastructure, are also AWS‘s responsibility. AWS manages these controls in their data centers to ensure the continuity and reliability of their services. Thus, these are also fully inherited by AWS customers.
Incorrect Options:
Awareness & Training Controls – Awareness and training controls involve making sure that employees understand their responsibilities regarding security, including both AWS-specific considerations and general security best practices. This responsibility typically falls to the customer, who needs to ensure that their employees are properly trained.
Patch Management Controls – Patch management is typically a customer responsibility. AWS is responsible for patching and fixing flaws within the infrastructure of the cloud, the customer is responsible for patching their guest OS and applications.
Configuration Management Controls – Configuration management involves ensuring that systems are configured according to agreed-upon policies and standards. AWS provides tools and features to assist with configuration management but the customer is typically responsible for setting up and managing their own configurations.

Question 10:
A company wants to track the history of resource changes. What service can help them do this?
A. AWS Config
B. AWS Personal Health Dashboard
C. Amazon CloudWatch
D. AWS CloudTrail
Answer: A
Explanation:
AWS Config – AWS Config enables you to assess, audit, and evaluate the configurations of your AWS resources. AWS Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations. This provides a history of configuration changes, which can be useful for operational troubleshooting, audit, and compliance use cases.
Incorrect Options:
Amazon CloudWatch – Amazon CloudWatch is a monitoring and observability service that provides you with data and actionable insights to monitor your applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health. It doesn‘t track resource configuration changes like AWS Config does.
AWS CloudTrail – AWS CloudTrail enables governance, compliance, operational auditing, and risk auditing of your AWS account. It helps you to log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. However, it is more about user activity and API usage rather than the history of resource configuration changes.
AWS Personal Health Dashboard – AWS Personal Health Dashboard provides alerts and remediation guidance when AWS is experiencing events that may impact your account. It‘s more about the health status of your AWS services rather than tracking changes in resource configurations.
