A genomic research institute, GenePulse, is migrating its legacy DNA sequencing analysis platform to AWS. The platform's application tier runs on legacy virtual machines, while its database tier uses a proprietary relational database that requires expensive licensing and intensive database administration. The institute wants to migrate to AWS to eliminate database licensing costs and minimize operational overhead, but it has strict timeline constraints that forbid modifying the application's core code or architecture. Which migration strategy should GenePulse adopt for this platform?

Cevabı ve açıklamayı göster

Cevap: Replatforming

Cevap

Replatforming
Replatforming is the correct strategy because it allows the organization to achieve direct benefits (such as shifting from a self-managed database to a fully managed service to eliminate licensing fees and reduce admin overhead) without changing the core application logic or architecture.

Adım Adım Çözüm

1
Identify the migration goals and constraints in the scenario.
The goals are to eliminate proprietary database licensing fees and reduce administration overhead. The key constraint is that the application's core code or architecture cannot be modified.
Understanding both what the customer wants to achieve and what they cannot change is required to select the correct migration strategy.
2
Compare the requirements against the characteristics of the migration strategies.
Rehosting is rejected because it keeps the proprietary database. Refactoring is rejected because it requires code changes. Repurchasing is rejected because the custom application is kept. Replatforming fits because shifting to a managed database service (e.g., Amazon RDS or Aurora) eliminates proprietary licenses and reduces administrative tasks without rewriting application code.
Evaluating each strategy ensures the selected option satisfies all operational goals while respecting the constraints.

Which of the following solutions represents the AWS-recommended best practice to grant the necessary permissions?

Cevabı ve açıklamayı göster

Cevap: Create an IAM role with S3 read permissions and associate it with the EC2 instance using an instance profile.

Cevap

Create an IAM role with S3 read permissions and associate it with the EC2 instance using an instance profile.
The correct option is to create an IAM role with S3 read permissions and associate it with the EC2 instance. This method uses temporary security credentials that are automatically distributed and rotated by AWS, fulfilling the security requirement of not storing long-term credentials on the instance.

Adım Adım Çözüm

1
Define permissions using an IAM policy that allows read-only access to the target Amazon S3 bucket.
An IAM policy document specifying the allowed S3 actions is created.
This establishes the minimum required permissions following the principle of least privilege.
2
Create an IAM role and attach the read-only S3 policy to it.
An IAM role is created with the necessary permissions associated.
An IAM role allows AWS services to assume permissions dynamically without long-term credentials.
3
Associate the IAM role with the EC2 instance via an instance profile.
The EC2 instance is now authorized to retrieve temporary credentials from the instance metadata service.
This enables the application to authenticate securely and automatically rotate credentials without hardcoding them.

Cevabı ve açıklamayı göster

Cevap: Writing and securing the application code running inside the Lambda functions; Configuring Identity and Access Management (IAM) execution roles for the Lambda functions

Cevap

Under the AWS Shared Responsibility Model for AWS Lambda, the customer is responsible for writing and securing the application code and configuring Identity and Access Management (IAM) execution roles.
In serverless compute services like AWS Lambda, the boundary of responsibility shifts upwards. AWS manages the physical security, virtual machines, operating system, and the runtime software stack. The customer remains responsible for configuration and data management, specifically securing the application code written for the function and configuring IAM execution roles to control access to other AWS resources.

Adım Adım Çözüm

1
Identify the AWS service model type for AWS Lambda.
AWS Lambda is a serverless (managed) service where physical infrastructure, virtualization, operating systems, and managed runtime environments are handled entirely by AWS.
Understanding the service model helps determine the boundary of shared responsibility.
2
Distinguish between responsibilities for security 'of' the cloud (AWS) and security 'in' the cloud (customer) for Lambda.
AWS secures the execution environment, OS patching, runtime version maintenance, and physical hardware. The customer secures their own code, configuration settings, and access control (IAM).
This separation determines the specific operational tasks assigned to each party.

Cevap: Ingest and queue the data streams using Amazon Simple Queue Service (Amazon SQS) queues between the ingestion and processing layers.; Deploy a serverless data processing pipeline using AWS Lambda functions that write results directly to Amazon DynamoDB.

Cevap

Ingest and queue the data streams using Amazon Simple Queue Service (Amazon SQS) queues between the ingestion and processing layers, and deploy a serverless data processing pipeline using AWS Lambda functions that write results directly to Amazon DynamoDB.
The correct architecture uses Amazon SQS to queue messages, which ensures that the ingestion and processing components are loosely coupled and can scale or fail independently without losing data. Additionally, using AWS Lambda and Amazon DynamoDB leverages the 'services, not servers' principle, allowing the company to build and run applications without the operational burden of provisioning and managing virtual servers.

Adım Adım Çözüm

1
Analyze the requirements for 'loose coupling' to find a solution that reduces interdependencies between components.
Amazon SQS acts as a message broker that decouples layers, allowing the processing layer to consume messages at its own pace without affecting the ingestion layer.
This isolates layers, satisfying the loose coupling principle.
2
Analyze the requirements for 'services, not servers' to find solutions that offload system administration.
AWS Lambda and Amazon DynamoDB are fully managed, serverless services that do not require provisioning, configuring, or managing virtual servers.
This satisfies the services, not servers principle by offloading operational overhead to AWS.
3
Evaluate the distractors against these principles to confirm why they are incorrect.
Monolithic architectures, hardcoded IP addresses, and manual vertical scaling of EC2 instances introduce tight coupling and significant administrative overhead.
These options are anti-patterns that contradict the target AWS design principles.

Cevap: Disposable resources, by replacing configuration-drifted servers with newly bootstrapped, standardized instances instead of updating them in place.

Cevap

Disposable resources, by replacing configuration-drifted servers with newly bootstrapped, standardized instances instead of updating them in place.
The strategy of terminating old servers and launching new, identical instances using automated templates (AWS CloudFormation) and pre-configured images (AMIs) demonstrates the principle of disposable resources. In cloud computing, resources should be treated as temporary and easily replaceable, which prevents configuration drift and ensures consistency across environments.

Adım Adım Çözüm

1
Identify the core problem described in the scenario.
The operations team is experiencing configuration drift and application failures due to manual, in-place server updates.
Understanding the problem helps identify which cloud design pattern directly addresses it.
2
Analyze the proposed solution.
The team will use AWS CloudFormation to automatically spin up new instances using a standard AMI and terminate the old ones.
This shows the team is moving away from maintaining long-running, manually updated servers and instead programmatically replacing them.
3
Map the solution to AWS cloud design principles.
Replacing resources programmatically rather than updating them in place corresponds to the design principle of 'disposable resources instead of fixed servers'.
This aligns with the AWS Well-Architected Framework recommendation to treat infrastructure as temporary and easily replaceable.

Cevap: Create individual IAM users for each team member and assign permissions by placing them in an IAM group with appropriate policies.; Enable Multi-Factor Authentication (MFA) for each individual user account and the AWS account root user.

Cevap

Create individual IAM users for each team member, manage their permissions using IAM groups, and enable Multi-Factor Authentication (MFA) on all accounts.
Establishing individual IAM users and organizing them into groups ensures that user activity is auditable and permissions adhere to the principle of least privilege. Requiring MFA for all users, including the root user, enforces a strong secondary layer of access validation to protect resources from credential leakage.

Adım Adım Çözüm

1
Evaluate the requirement for individual accountability and permission control.
Determine that shared credentials must be avoided and that permissions must be managed centrally and specifically for roles.
Creating individual IAM users ensures that all actions can be audited to a specific person, while IAM groups allow efficient distribution of minimum necessary permissions.
2
Evaluate identity authentication security measures.
Determine that Multi-Factor Authentication (MFA) should be enforced for all administrative and root accounts.

Cevap: Retrieve the AWS PCI DSS compliance reports and Attestation of Compliance (AoC) from AWS Artifact.

Cevap

Retrieve the AWS PCI DSS compliance reports and Attestation of Compliance (AoC) from AWS Artifact.
Under the AWS Shared Responsibility Model, AWS is responsible for security of the cloud, which includes the physical security of data centers. Because customers cannot access or physically audit AWS data centers, AWS undergoes independent third-party audits to verify compliance. The resulting compliance reports, such as the PCI DSS Attestation of Compliance (AoC), are made available on-demand to customers via AWS Artifact.

Adım Adım Çözüm

1
Identify the compliance requirement and responsibility boundary.
The requirement is to verify the physical security and compliance of AWS data centers. Under the Shared Responsibility Model, AWS is solely responsible for physical security.
Since customers have no physical access to AWS facilities, they must rely on third-party audits performed on AWS's infrastructure.
2
Determine the AWS service that provides access to third-party compliance reports.

An enterprise is migrating its legacy document-indexing application to AWS. The application currently runs on a cluster of self-managed virtual machines that parse uploaded files, extract text, and index the content into a local database. The migration team's initial plan is to deploy a fleet of Amazon EC2 instances in an Auto Scaling group, running a self-managed search index cluster on those instances. A solutions architect reviews this plan and recommends replacing the self-managed search index cluster with Amazon OpenSearch Service, and using AWS Lambda to trigger the parsing and indexing process directly from Amazon S3 uploads. Which design principle of the AWS Cloud is the architect primarily advocating for by recommending Amazon OpenSearch Service and AWS Lambda over self-managed EC2 instances?

Cevabı ve açıklamayı göster

Cevap: Services not servers

Cevap

Services not servers
The correct answer is 'Services not servers'. This design principle encourages utilizing managed services (such as Amazon OpenSearch Service) and serverless technologies (such as AWS Lambda) to offload the operational burden of provisioning, configuring, patching, and securing physical servers and operating systems. This allows the organization to focus on writing code and developing features rather than managing infrastructure.

Adım Adım Çözüm

1
Analyze the migration team's initial architecture.
The initial design relies on Amazon EC2 instances running self-managed virtual servers and a self-managed search cluster.
Understanding the baseline helps identify what operational overhead is present.
2
Evaluate the solutions architect's proposed recommendations.
The architect suggests using Amazon OpenSearch Service (a managed service) and AWS Lambda (a serverless service) instead of self-managed virtual machines.
Identifying the target services determines the operational model transition.
3
Map the change in operational model to AWS Cloud design principles.
Moving from self-managed servers on EC2 to fully managed and serverless offerings directly shifts administrative tasks (like OS patching, server provisioning, and cluster management) to AWS, which represents the principle of 'services not servers'.
This links the architecture recommendation to the correct design principle.

Which of the following tasks remains the sole responsibility of the customer under the AWS Shared Responsibility Model?

Cevabı ve açıklamayı göster

Cevap: Configuring security group rules to restrict network access to the EC2 instances and applying updates to the application code.

Cevap

Configuring security group rules to restrict network access to the EC2 instances and applying updates to the application code.
The correct option is correct because managing security groups and application code are customer responsibilities (security 'in' the cloud). Even though AWS Elastic Beanstalk automates deployment, the provisioned EC2 instances run in the customer's environment, leaving network access rules (security groups) and code security under the customer's control.

Adım Adım Çözüm

1
Analyze the service model in the scenario.
AWS Elastic Beanstalk is a Platform as a Service (PaaS) that provisions standard Infrastructure as a Service (IaaS) resources, including Amazon EC2 instances, under the customer's control.
Identifying the service model helps determine where the boundary of responsibility lies for the operating system and network settings.
2
Differentiate between security 'of' the cloud and security 'in' the cloud.
AWS manages the physical infrastructure, virtualization hypervisors, and data center facilities. The customer manages the guest operating system, network firewalls (security groups), and application code.
Applying the Shared Responsibility Model principles isolates customer duties from AWS duties.
3
Evaluate the choices based on the customer's operational responsibilities.
Configuring security groups and updating application code are customer duties (security 'in' the cloud), whereas physical security, hypervisor patching, and data center compliance belong to AWS.
Verifying each option ensures the correct option matches the customer's responsibility profile.

Create an IAM group to manage the customer support users collectively, and attach the Amazon S3 read-only IAM policy directly to that group.
The correct practices involve creating an IAM group to manage the customer support team collectively and attaching the S3 read-only IAM policy directly to that group. This aligns with the AWS best practice of using groups to manage permissions for multiple users with similar access needs, ensuring administrative overhead is reduced and permissions are inherited consistently.

Adım Adım Çözüm

1
Group creation
An IAM group is created for the customer support team, and individual IAM user accounts are created for each agent and added to this group.
This establishes a logical boundary for managing permissions for a team of people with the same job function, following standard identity management practices.
2
Policy attachment
The S3 read-only IAM policy is attached directly to the group.
By attaching the policy to the group, all users added to the group automatically inherit the required permissions without needing direct policy assignment.
