Question 1
A company plans to use an Amazon Snowball Edge device to transfer files to the AWS Cloud.
Which activities related to a Snowball Edge device are available to the company at no cost?
- A. Use of the Snowball Edge appliance for a 10-day period
- B. The transfer of data out of Amazon S3 and to the Snowball Edge appliance
- C. The transfer of data from the Snowball Edge appliance into Amazon S3
- D. Daily use of the Snowball Edge appliance after 10 days
Correct Answer:
C
Explanation:
I agree with the suggested answer. The correct answer is C. The transfer of data from the Snowball Edge appliance into Amazon S3.
Reasoning:
Data transfer IN to AWS (in this case, from Snowball Edge to S3) is generally free. AWS charges for data transfer OUT of AWS.
- AWS primarily charges for compute, storage, and outbound data transfer. Inbound data transfer is usually free.
Why other options are incorrect:
- A: Use of the Snowball Edge appliance for a 10-day period - This is incorrect because using the Snowball Edge appliance incurs a service fee and a per-day fee, as stated in the AWS documentation.
- B: The transfer of data out of Amazon S3 and to the Snowball Edge appliance - This is incorrect because outbound data transfer from S3 to the Snowball Edge appliance would incur data transfer costs.
- D: Daily use of the Snowball Edge appliance after 10 days - This is incorrect because there are per-day charges associated with the Snowball Edge appliance usage beyond the initial period.
Therefore, Option C is the only activity related to a Snowball Edge device that is available at no cost.

Question 2
A company has deployed applications on Amazon EC2 instances. The company needs to assess application vulnerabilities and must identify infrastructure deployments that do not meet best practices.
Which AWS service can the company use to meet these requirements?
- A. AWS Trusted Advisor
- B. Amazon Inspector
- C. AWS Config
- D. Amazon GuardDuty
Correct Answer:
B
Explanation:
I agree with the suggested answer, which is Amazon Inspector.
Reasoning:
Amazon Inspector is specifically designed to assess applications running on EC2 instances for vulnerabilities and deviations from security best practices. It performs automated security assessments to help improve the security and compliance of applications deployed on AWS. The question explicitly asks for a service that can assess application vulnerabilities and identify infrastructure deployments that do not meet best practices. Amazon Inspector directly addresses these requirements by:
- Scanning EC2 instances for vulnerabilities.
- Identifying security issues and providing remediation guidance.
- Assessing applications against security best practices.
Reasons for not choosing the other options:
- AWS Trusted Advisor: Provides recommendations on cost optimization, performance, security, and fault tolerance. It offers high-level advice across an entire AWS account, but it is not focused on in-depth application vulnerability assessments.
- AWS Config: Tracks resource configurations and evaluates them against desired configurations. While it can help with compliance, it doesn't perform vulnerability scanning like Inspector.
- Amazon GuardDuty: A threat detection service that monitors for malicious activity and unauthorized behavior. It's focused on identifying threats rather than assessing application vulnerabilities.
Therefore, Amazon Inspector is the most suitable service for the stated requirements.

Question 3
A company has a centralized group of users with large file storage requirements that have exceeded the space available on premises. The company wants to extend its file storage capabilities for this group while retaining the performance benefit of sharing content locally.
What is the MOST operationally efficient AWS solution for this scenario?
- A. Create an Amazon S3 bucket for each user. Mount each bucket by using an S3 file system mounting utility.
- B. Configure and deploy an AWS Storage Gateway file gateway. Connect each user’s workstation to the file gateway.
- C. Move each user’s working environment to Amazon WorkSpaces. Set up an Amazon WorkDocs account for each user.
- D. Deploy an Amazon EC2 instance and attach an Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS volume. Share the EBS volume directly with the users.
Correct Answer:
B
Explanation:
I agree with the suggested answer, which is B. Configure and deploy an AWS Storage Gateway file gateway. Connect each user’s workstation to the file gateway.
Reasoning:
The scenario requires extending file storage capabilities while retaining the performance benefit of local content sharing. AWS Storage Gateway, specifically the file gateway type, is designed for this hybrid cloud storage use case. It allows on-premises applications to seamlessly access data stored in Amazon S3 with local caching for frequently accessed files, addressing both the storage extension and performance requirements.
Why other options are not suitable:
- A. Create an Amazon S3 bucket for each user. Mount each bucket by using an S3 file system mounting utility: Mounting S3 buckets directly on each workstation can be complex to manage and might not provide the same level of integration and local caching as a file gateway.
- C. Move each user’s working environment to Amazon WorkSpaces. Set up an Amazon WorkDocs account for each user: This solution involves migrating user environments, which is a more extensive change than simply extending storage. It doesn't directly address the requirement of retaining the performance benefits of local file sharing for existing on-premises workflows.
- D. Deploy an Amazon EC2 instance and attach an Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS volume. Share the EBS volume directly with the users: This approach involves managing an EC2 instance and EBS volume, which adds operational overhead. It also doesn't inherently provide the hybrid cloud storage benefits of AWS Storage Gateway, such as integration with S3 and local caching.

Question 4
According to security best practices, how should an Amazon EC2 instance be given access to an Amazon S3 bucket?
- A. Hard code an IAM user’s secret key and access key directly in the application, and upload the file.
- B. Store the IAM user’s secret key and access key in a text file on the EC2 instance, read the keys, then upload the file.
- C. Have the EC2 instance assume a role to obtain the privileges to upload the file.
- D. Modify the S3 bucket policy so that any service can upload to it at any time.
Correct Answer:
C
Explanation:
I agree with the suggested answer.
The correct answer is C. Have the EC2 instance assume a role to obtain the privileges to upload the file.
Reasoning:
IAM roles are the recommended way to grant permissions to EC2 instances. Instead of storing long-term credentials (like IAM user access keys) on the instance, you assign a role to the instance. This role provides temporary credentials that the application on the instance can use to access AWS services, such as S3. This approach is more secure and easier to manage. It follows the principle of least privilege, granting only the necessary permissions to the EC2 instance.
Why the other options are incorrect:
- A. Hard coding IAM user credentials in the application is a very bad security practice. If the code is compromised, the credentials are compromised as well.
- B. Storing IAM user credentials in a file on the EC2 instance is also a bad security practice. If the instance is compromised, the credentials can be easily accessed.
- D. Modifying the S3 bucket policy to allow any service to upload to it is overly permissive and creates a significant security risk.

Question 5
Which option is a customer responsibility when using Amazon DynamoDB under the AWS Shared Responsibility Model?
- A. Physical security of DynamoDB
- B. Patching of DynamoDB
- C. Access to DynamoDB tables
- D. Encryption of data at rest in DynamoDB
Correct Answer:
C
Explanation:
I agree with the suggested answer. The correct answer is C. Access to DynamoDB tables.
Reasoning:
The AWS Shared Responsibility Model clearly delineates responsibilities between AWS and the customer. In the context of Amazon DynamoDB:
-
AWS is responsible for the security of the cloud, which includes the physical security of the infrastructure, patching the DynamoDB service, and providing encryption at rest as a managed service.
-
Customers are responsible for security in the cloud. This includes managing access to their DynamoDB tables, which involves configuring IAM policies and permissions to control who can access and perform actions on the tables.
Why other options are incorrect:
-
A. Physical security of DynamoDB: This is AWS's responsibility as part of the security of the cloud.
-
B. Patching of DynamoDB: AWS handles the patching and maintenance of the DynamoDB service itself.
-
D. Encryption of data at rest in DynamoDB: AWS provides encryption at rest as a managed feature. While customers might configure certain encryption settings, the underlying encryption mechanism is managed by AWS.
Therefore, access management is the primary customer responsibility related to DynamoDB security.
-
Question 6
Which option is a perspective that includes foundational capabilities of the AWS Cloud Adoption Framework (AWS CAF)?
- A. Sustainability
- B. Performance efficiency
- C. Governance
- D. Reliability
Correct Answer:
C
Explanation:
I agree with the suggested answer.
The recommended answer is C. Governance because Governance is a key perspective within the AWS Cloud Adoption Framework (CAF) that focuses on establishing and implementing policies, processes, and controls to effectively manage and govern cloud resources. It is foundational because it provides the framework for making informed decisions, managing risks, and ensuring compliance within the cloud environment.
Here's why the other options are less suitable:
- A. Sustainability: While sustainability is an important consideration, it is not explicitly identified as a foundational perspective within the core AWS CAF documentation.
- B. Performance efficiency: Performance efficiency is a pillar of the AWS Well-Architected Framework, which complements the CAF but is not a foundational CAF perspective itself.
- D. Reliability: Similar to performance efficiency, reliability is a pillar of the AWS Well-Architected Framework, rather than a core perspective of the AWS CAF.
The AWS CAF helps organizations identify and address gaps in skills and processes, and Governance provides the structure for managing cloud adoption.

Question 7
A company is running and managing its own Docker environment on Amazon EC2 instances. The company wants an alternative to help manage cluster size, scheduling, and environment maintenance.
Which AWS service meets these requirements?
- A. AWS Lambda
- B. Amazon RDS
- C. AWS Fargate
- D. Amazon Athena
Correct Answer:
C
Explanation:
I agree with the suggested answer. AWS Fargate is the correct choice because it directly addresses the company's need for an alternative to managing their own Docker environment on EC2 instances. Fargate is a serverless compute engine for containers, allowing them to run containers without the overhead of managing the underlying infrastructure like cluster sizing, scheduling, and environment maintenance.
Reasoning:
Fargate is specifically designed to abstract away the complexities of container management, letting the user focus on the containers themselves rather than the infrastructure.
- It handles cluster size automatically, scaling up or down as needed based on the application's demands.
- It manages the scheduling of containers, ensuring they are placed on appropriate resources.
- It takes care of environment maintenance, including patching and updating the underlying infrastructure.
Reasons for eliminating other options:
- A. AWS Lambda: Lambda is a serverless compute service, but it's designed for event-driven functions, not for running and managing Docker containers. It's not a direct alternative for a Docker environment.
- B. Amazon RDS: RDS is a managed relational database service. It doesn't manage or run containers.
- D. Amazon Athena: Athena is a serverless interactive query service for data stored in Amazon S3. It's not related to container management.
Therefore, Fargate is the only service among the choices that meets the company's requirements for an alternative to managing their own Docker environment on EC2 instances.

Question 8
A company wants to run a NoSQL database on Amazon EC2 instances.
Which task is the responsibility of AWS in this scenario?
- A. Update the guest operating system of the EC2 instances.
- B. Maintain high availability at the database layer.
- C. Patch the physical infrastructure that hosts the EC2 instances.
- D. Configure the security group firewall.
Correct Answer:
C
Explanation:
The suggested answer of C is correct.
Reasoning: When a company runs a NoSQL database on Amazon EC2 instances, AWS is responsible for the underlying physical infrastructure. This includes patching and maintaining the hardware, network, and facilities that host the EC2 instances. This division of responsibility is part of the AWS shared responsibility model.
Specifically, AWS handles tasks like:
- Patching the physical infrastructure.
- Maintaining the hardware.
- Ensuring the network is functional.
The other options are incorrect because they fall under the customer's responsibility according to the AWS shared responsibility model:
- A. Update the guest operating system of the EC2 instances: This is the customer's responsibility. The customer manages the operating system, including updates and patches, within their EC2 instances.
- B. Maintain high availability at the database layer: While AWS provides services that *can* help with high availability (like Auto Scaling and Elastic Load Balancing), the configuration and management of high availability for the database itself is the customer's responsibility. AWS ensures the underlying infrastructure is available, but the application-level HA is managed by the customer.
- D. Configure the security group firewall: Security Groups are a customer-configurable firewall for EC2 instances. The customer is responsible for defining and managing these rules.
The AWS Shared Responsibility Model clearly defines these boundaries.

Correct Answer:
AE
Explanation:
I agree with the suggested answer (AE).
Reasoning:
- AWS Cost Explorer: This service helps you visualize, understand, and manage your AWS costs and usage over time. It can identify trends and potential areas for cost optimization, including identifying underutilized EC2 instances.
- AWS Compute Optimizer: This service analyzes the configuration and utilization metrics of your AWS resources and recommends optimal AWS resources for your workloads. It helps identify rightsizing opportunities for EC2 instances by suggesting instance types that better match your workload requirements.
Reasons for excluding other options:
- B. AWS Billing Conductor: There appears to be some confusion. While AWS Billing Conductor exists, its primary function is to customize billing data for different groups within an organization, rather than providing rightsizing recommendations.
- C. Amazon CodeGuru: This service focuses on code analysis and optimization, not infrastructure rightsizing.
- D. Amazon SageMaker: This is a machine learning platform and does not provide EC2 rightsizing recommendations.
Therefore, options A and E are the most appropriate choices.

- A. Providing high-performance container orchestration
- B. Creating and rotating encryption keys
- C. Detecting underutilized resources to save costs
- D. Improving security by proactively monitoring the AWS environment
- E. Implementing enforced tagging across AWS resources
Correct Answer:
CD
Explanation:
I agree with the suggested answer (C and D).
Reasoning: AWS Trusted Advisor is designed to provide recommendations that help you follow AWS best practices. Its benefits include cost optimization through the detection of underutilized resources and enhanced security by proactively monitoring the AWS environment for potential vulnerabilities. Options C and D align perfectly with these core functionalities.
Reasons for not choosing other options:
- A: High-performance container orchestration is primarily handled by services like Amazon ECS, Amazon EKS, or AWS Fargate, not Trusted Advisor.
- B: Creating and rotating encryption keys is a function of AWS Key Management Service (KMS) or AWS CloudHSM, not Trusted Advisor.
- E: Implementing enforced tagging across AWS resources can be achieved using AWS Tag Policies and AWS Config, but it is not a direct function of Trusted Advisor.
Trusted Advisor focuses on five pillars: Cost Optimization, Security, Fault Tolerance, Performance, and Service Limits. The correct options directly reflect its capabilities in Cost Optimization and Security.
- Cost optimization: Detecting underutilized resources directly contributes to cost savings.
- Security: Proactively monitoring the AWS environment helps identify and mitigate security risks.
