Question 1:
Which of the following combination of steps will help accomplish the goals of a DevOps Engineer who must ensure all IAM entity configurations across multiple AWS accounts in AWS Organizations are compliant with corporate IAM policies?
A. Deploy AWS Config rules to all accounts in Organizations that match the corporate IAM policies.
B. Enable AWS Trusted Advisor in Organizations for all accounts to report on noncompliant IAM entities.
C. Deploy AWS Config rules to the master account in Organizations that match corporate IAM policies.
D. Apply an SCP in Organizations to ensure compliance of IAM entities.
Answer: A
Explanation:
AWS Config Rules: By deploying AWS Config rules across all accounts, you can continuously monitor and evaluate the configurations of IAM entities against the established corporate IAM policies. This ensures that any non-compliance is flagged in real-time.
Organizational Scope: AWS Config can be set up to evaluate compliance across multiple accounts within an AWS Organization, providing a centralized view of IAM compliance status.
Automated Compliance Checks: This approach automates compliance checks, making it easier to maintain adherence to corporate policies and quickly identify any issues that need to be addressed.
Incorrect Options:
B. Enable AWS Trusted Advisor in Organizations for all accounts to report on noncompliant IAM entities.
This option is incorrect because:
Limited Scope: While AWS Trusted Advisor provides insights and recommendations for best practices, it does not offer comprehensive compliance monitoring specifically tailored to corporate IAM policies. Trusted Advisor checks are more general and do not provide the detailed compliance enforcement capabilities that AWS Config does.
Reactive, Not Proactive: Trusted Advisor reports are not automatically enforced; they are advisory in nature. This means that relying solely on Trusted Advisor would not ensure compliance but rather inform about potential issues after the fact.
C. Deploy AWS Config rules to the master account in Organizations that match corporate IAM policies.
This option is incorrect because:
Limited Coverage: Deploying AWS Config rules only to the master account does not cover the entire organization. Compliance checks need to be applied across all accounts to ensure that IAM entities are compliant in every account within the organization.
Ineffective for Multi-Account Management: This approach would leave other accounts unmonitored for compliance, which could lead to non-compliance issues going unnoticed.
D. Apply an SCP in Organizations to ensure compliance of IAM entities.
This option is incorrect because:
Service Control Policies (SCPs): While SCPs can help manage permissions across accounts, they do not evaluate or enforce compliance with IAM policies. SCPs are used to control the maximum available permissions for IAM entities but do not provide a mechanism for checking compliance against specific policies.
Lack of Monitoring: SCPs do not provide monitoring capabilities or reporting on compliance status, which is essential for ensuring that IAM configurations adhere to corporate policies.
Question 2:
Which of the following actions will accomplish the goals of a company that is running an application on Amazon EC2 instances in an Auto Scaling group, provided that recently an issue occurred that prevented EC2 instances from launching successfully, and it took several hours for the Support team to discover the issue and the support team wants to be notified by email whenever an EC2 instance does not start successfully.
A. Create a status check alarm on Amazon EC2 to send a notification to an Amazon SNS topic whenever a status check fail occurs.
B. Add a health check to the Auto Scaling group to invoke an AWS Lambda function whenever an instance status is impaired.
C. Configure the Auto Scaling group to send a notification to an Amazon SNS topic whenever a failed instance launch occurs.
D. Create an Amazon CloudWatch alarm that invokes an AWS Lambda function when a failed AttachInstances Auto Scaling API call is made.
Answer: C
Explanation:
C. Configure the Auto Scaling group to send a notification to an Amazon SNS topic whenever a failed instance launch occurs.
This option directly addresses the requirement by configuring the Auto Scaling group to send notifications to an Amazon SNS topic when a failed instance launch occurs. This ensures that the support team receives an email notification whenever an instance fails to launch, allowing them to respond promptly1.
Incorrect Options:
A. Create a status check alarm on Amazon EC2 to send a notification to an Amazon SNS topic whenever a status check fail occurs.
While creating a status check alarm can notify the team of general instance health issues, it does not specifically address the scenario of failed instance launches. Status check alarms are more suited for monitoring the health of running instances rather than capturing launch failures.
B. Add a health check to the Auto Scaling group to invoke an AWS Lambda function whenever an instance status is impaired.
Adding a health check to invoke a Lambda function for impaired instance status is useful for handling unhealthy instances, but it does not specifically notify the team about failed instance launches. This option focuses on instances that are already running but have become unhealthy.
D. Create an Amazon CloudWatch alarm that invokes an AWS Lambda function when a failed AttachInstances Auto Scaling API call is made.
This option involves creating a CloudWatch alarm for a specific API call failure, which is not directly related to instance launch failures. The AttachInstances API call is used to attach instances to an Auto Scaling group, and monitoring this does not address the requirement of notifying about failed instance launches.
Question 3:
Which of the following attributes could not be defined under the Ansible Inventory system?
A. Children groups
B. Group variables
C. Host groups
D. Include vars
Answer: D
Explanation:
The attributes that can be defined under the Ansible Inventory system are:
Children groups: These are groups within groups, allowing for hierarchical organization of hosts.
Group variables: These are variables that apply to all hosts within a group.
Host groups: These are groups of hosts that share common characteristics or are used for specific purposes.
Therefore, the attribute that could not be defined under the Ansible Inventory system is:
Include vars.
While “include vars” is a valid Ansible syntax for including variable files, it is not an attribute that can be directly defined within the inventory file itself. Instead, it is used to include external variable files that contain variables that can be used in your Ansible playbooks.
Question 4:
Which of the following options is the most suitable action for you when you have decided that you need to change the instance type of your production instances which are running as part of an AutoScaling group and the entire architecture is deployed using CloudFormation Template, it is observed that you currently have 4 instances in Production and you cannot have any interruption in service and need to ensure 2 instances are always running during the update.
A. AutoScalinglntegrationUpdate
B. AutoScalingRollingUpdate
C. AutoScalingScheduledAction
D. AutoScalingReplacingUpdate
Answer: B
Explanation:
The AWS::AutoScaling::AutoScalingGroup resource supports an UpdatePoIicy attribute. This is used to define how an Auto Scalinggroup resource is updated when an update to the Cloud Formation stack occurs. A common approach to updating an Auto Scaling group is to perform a rolling update, which is done by specifying the AutoScalingRollingUpdate policy. This retains the same Auto Scaling group and replaces old instances with new ones, according to the parameters specified. For more information on Autoscaling updates, please refer to the below link.
Question 5:
Showing the instances as healthy, which of the following could be the ultimate issue faced by an application running a specific process that is critical to the application’s functionality, and have added the health check process to your Auto Scaling Group and it is observed that the application itself is not working as it should.
A. The health check is not checking the application process
B. You do not have the time range in the health check properly configured
C. It is not possible for a health check to monitor a process that involves the application
D. The health check is not configured properly
Answer: A
Explanation:
If you have custom health checks, you can send the information from your health checks to Auto Scaling so that Auto Scaling can use this information. For example, if you determine that an instance is not functioning as expected, you can set the health status of the instance to Unhealthy. The next time that Auto Scaling performs a health check on the instance, it will determine that the instance is unhealthy and then launch a replacement instance.

Question 6:
Which of the following is the potential reason behind issues faced by an application which is recently deployed on EC2 instances behind an ELB, provided that after a couple of weeks, customers are complaining on receiving errors from the application and you want to diagnose the errors and are trying to get errors from the ELB access logs but it is given that the ELB access logs are empty.
A. Access logging is an optional feature of Elastic Load Balancing that is disabled by default
B. You do not have the appropriate permissions to access the logs
C. You do not have your CloudWatch metrics correctly configured
D. ELB Access logs are only available for a maximum of one week
Answer: A
Explanation:
Elastic Load Balancing provides access logs that capture detailed information about requests sent to your load balancer. Cach log contains information such as the time the request was received, the client’s IP address, latencies, request paths, and server responses. You can use these access logs to analyze traffic patterns and to troubleshoot issues. Access logging is an optional feature of Elastic Load Balancing that is disabled by default. After you enable access logging for your load balancer. Clastic Load Balancing captures the logs and stores them in the Amazon S3 bucket that you specify. You can disable access logging at any time.
Question 7:
Which of the following options is one of the action items to be achieved for the deployment of an application to AWS which makes use of Auto Scaling to launch new instances and you now want to change the instance type for the new instances.
A. Create new EC2 instances with the new instance type and attach it to the Autoscaling Group
B. Use Elastic Beanstalk to deploy the new application with the new instance type
C. Use Cloudformation to deploy the new application with the new instance type
D. Create a new launch configuration with the new instance type
Answer: D
Explanation:
The ideal way is to create a new launch configuration, attach it to the existing Auto Scaling group, and terminate the running instances. Option A is invalid because Clastic beanstalk cannot launch new instances on demand. Since the current scenario requires Autoscaling, this is not the ideal option Option B is invalid because this will be a maintenance overhead, since you just have an Autoscaling Group. There is no need to create a whole Cloudformation template for this. Option D is invalid because Autoscaling Group will still launch CC2 instances with the older launch configuration.
Question 8:
While still keeping them in your Auto Scaling Group, which of the following Auto Scaling processes would be helpful when testing new instances before sending traffic to them?
A. Suspend the process AddToLoadBalancer
B. Suspend the process AZ Rebalance
C. Suspend the process Health Check
D. Suspend the process Replace Unhealthy
Answer: A
Explanation:
If you suspend Add To Load Balancer, Auto Scaling launches the instances but does not add them to the load balancer or target group. If you resume the Add To Load Balancer process. Auto Scaling resumes adding instances to the load balancer or target group when they are launched. However, Auto Scaling does not add the instances that were launched while this process was suspended. You must register those instances manually. Option A is invalid because this just balances the number of CC2 instances in the group across the Availability Zones in the region Option B is invalid because this just checks the health of the instances. Auto Scaling marks an instance as unhealthy if Amazon CC2 or Clastic Load Balancing tells Auto Scaling that the instance is unhealthy. Option C is invalid because this process just terminates instances that are marked as unhealthy and later creates new instances to replace them.
Question 9:
Which of the following options can suffice the requirements of an ELB setup in AWS with EC2 instances running behind it and you have been requested to monitor the incoming connections to the ELB?
A. Create a custom metric CloudWatch filter on your load balancer
B. Use AWSCIoudTrail with your load balancer
C. Enable access logs on the load balancer
D. Use a CloudWatch Logs Agent
Answer: C
Explanation:
Clastic Load Balancing provides access logs that capture detailed information about requests sent to your load balancer. Cach log contains information such as the time the request was received, the client’s IP address, latencies, request paths, and server responses. You can use these access logs to analyze traffic patterns and to troubleshoot issues.
Question 10:
Which of the following options shall a devops engineer choose in order to meet the requirements of a company that uses Amazon S3 to store proprietary information, it is observed that the Development team creates buckets for new projects on a daily basis and the Security team wants to ensure that all existing and future buckets have encryption, logging, and versioning enabled, provided no buckets should ever be publicly read or write accessible.
A. Enable AWS Systems Manager and configure automatic remediation using Systems Manager documents.
B. Enable AWS CloudTrail and configure automatic remediation using AWS Lambda.
C. Enable AWS Config rules and configure automatic remediation using AWS Systems Manager documents.
D. Enable AWS Trusted Advisor and configure automatic remediation using Amazon CloudWatch Events.
Answer: C
Explanation:
AWS Config rules: Continuously monitor S3 buckets for changes and evaluate their compliance against defined rules.
Automatic remediation using AWS Systems Manager documents: Automate the process of modifying non-compliant buckets to enforce encryption, logging, and versioning.
Comprehensive coverage: Ensures both existing and future buckets are managed, preventing accidental misconfigurations.
Scalability: Handles large numbers of buckets efficiently.
This solution offers a proactive and scalable approach to maintaining security best practices for S3 buckets.
