A company has developed a service that is deployed on a fleet of Linux-based Amazon EC2 instances that are in an Auto Scaling group. The service occasionally fails unexpectedly because of an error in the application code. The company's engineering team determines that resolving the underlying cause of the service failure could take several weeks. A SysOps administrator needs to create a solution to automate recovery if the service crashes on any of the EC2 instances. Which solutions will meet this requirement? (Select TWO.)
A. Install the Amazon CloudWatch agent on the EC2 instances. Configure the CloudWatchagent to monitor the service. Set the CloudWatch action to restart if the service healthcheck fails.
B. Tag the EC2 instances. Create an AWS Lambda function that uses AWS SystemsManager Session Manager to log in to the tagged EC2 instances and restart the service.Schedule the Lambda function to run every 5 minutes.
C. Tag the EC2 instances. Use AWS Systems Manager State Manager to create anassociation that uses the AWS-RunSheIIScript document. Configure the associationcommand with a script that checks if the service is running and that starts the service if theservice is not running. For targets, specify the EC2 instance tag. Schedule the associationto run every 5 minutes.
D. Update the EC2 user data that is specified in the Auto Scaling group's launch templateto include a script that runs on a cron schedule every 5 minutes.
E. Update the EC2 user data that is specified in the Auto Scaling group's launch templateto ensure that the service runs during startup. Redeploy all the EC2 instances in the AutoScaling group with the updated launch template.
Users of a company's internal web application recently experienced application performance issues for a brief period The application includes frontend web servers that run in an Amazon Elastic Kubernetes Service (Amazon EKS) cluster The application also includes a bacKend Amazon Aurora PostgreSQL DB cluster that includes one DB instance. A SysOps administrator determines that the source of the performance issues was high utilization of the DB cluster. The single writer instance experienced more than 90% utilization for 11 minutes The cause of the high utilization was an automated report that is scheduled to run one time each week What should the SysOps administrator do to ensure that users do not experience performance Issues each week when the report runs?
A. Increase the size of the DB instance. Monitor the performance during the nextscheduled run of the report
B. Add a reader instance. Change the database connection string of the report applicationto use the newly created reader instance.
C. Add another writer instance Change the database connection string of the reportapplication to use the newly created writer instance.
D. Configure auto scaling for the DB cluster Set the minimum capacity units, maximumcapacity units, and target utilization
A company has an application that collects notifications from thousands of alarm systems. The notifications include alarm notifications and information notifications. The information notifications include the system arming processes, disarming processes, and sensor status. All notifications are kept as messages in an Amazon Simple Queue Service (Amazon SQS) queue. Amazon EC2 instances that are in an Auto Scaling group process the messages. A SysOps administrator needs to implement a solution that prioritizes alarm notifications over information notifications. Which solution will meet these requirements?
A. Adjust the Auto Scaling group to scale faster when a high number of messages is in thequeue.
B. Use the Amazon Simple Notification Service (Amazon SNS) fanout feature with AmazonSQS to send the notifications in parallel to all the EC2 instances.
C. Add an Amazon DynamoDB stream to accelerate the message processing.
D. Create a queue for alarm notifications and a queue for information notifications. Updatethe application to collect messages from the alarm notifications queue first.
A company that uses AWS Organizations recently implemented AWS Control Tower The company now needs to centralize identity management A SysOps administrator must federate AWS 1AM Identity Center with an external SAML 2.0 identity provider (IdP) to centrally manage access to all the company's accounts and cloud applications Which prerequisites must the SysOps administrator have so that the SysOps administrator can connect to the external IdP? (Select TWO.)
A. A copy of the 1AM Identity Center SAML metadata
B. The IdP metadata, including the public X.509 certificate
C. The IP address of the IdP
D. Root access to the management account
E. Administrative permissions to the member accounts of the organization
A company uses AWS Organizations to manage its multi-account environment. The organization contains a dedicated account for security and a dedicated account for logging. A SysOps administrator needs to implement a centralized solution that provides alerts when a resource metric in any account crosses a standard defined threshold. Which solution will meet these requirements?
A. Deploy an AWS CloudFormation stack set to the accounts in the organization. Use atemplate that creates the required Amazon CloudWatch alarms and references an AmazonSimple Notification Service (Amazon SNS) topic in the logging account with publishpermissions for all the accounts.
B. Deploy an AWS CloudFormation stack in each account. Use the stack to deploy therequired Amazon CloudWalch alarms and the required Amazon Simple Notification Service(Amazon SNS) topic.
C. Deploy an AWS Lambda function on a cron job in each account. Configure the Lambdafunction to read resources that are in the account and to invoke an Amazon SimpleNotification Service (Amazon SNS) topic if any metrics cross the defined threshold.
D. Deploy an AWS CloudFormation change set to the organization. Use a template tocreate the required Amazon CloudWatch alarms and to send alerts to a verified AmazonSimple Email Service (Amazon SES) identity.
A company hosts a production MySQL database on an Amazon Aurora single-node DB cluster. The database is queried heavily for reporting purposes. The DB cluster is experiencing periods of performance degradation because of high CPU utilization and maximum connections errors. A SysOps administrator needs to improve the stability of the database. Which solution will meet these requirements?
A. Create an Aurora Replica node. Create an Auto Scaling policy to scale replicas basedon CPU utilization. Ensure that all reporting requests use the read-only connection string.
B. Create a second Aurora MySQL single-node DB cluster in a second Availability Zone.Ensure that all reporting requests use the connection string for this additional node.
C. Create an AWS Lambda function that caches reporting requests. Ensure that allreporting requests call the Lambda function.
D. Create a multi-node Amazon ElastiCache cluster. Ensure that all reporting requests usethe ElastiCache cluster. Use the database if the data is not in the cache.
A company runs its web application on multiple Amazon EC2 instances that are part of an Auto Scaling group. The company wants the Auto Scaling group to scale out as soon as CPU utilization rises above 50% for the instances. How should a SysOps administrator configure the Auto Scaling group to meet these requirements?
A. Configure the Auto Scaling group to scale based on events.
B. Configure the Auto Scaling group to scale based on a schedule.
C. Configure the Auto Scaling group to scale dynamically based on demand.
D. Configure the Auto Scaling group to use predictive scaling.
A company manages its production applications across several AWS accounts. The company hosts the production applications on Amazon EC2 instances that run Amazon Linux 2. The EC2 instances are spread across multiple VPCs. Each VPC uses its own Amazon Route 53 private hosted zone for private DNS. A VPC from Account A needs to resolve private DNS records from a private hosted zone that is associated with a different VPC in Account B. What should a SysOps administrator do to meet these requirements?
A. In Account A, create an AWS Systems Manager document that updates the/etc/resolv.conf file across all EC2 instances to point to the AWS provided default DNSresolver for the VPC in Account B.
B. In Account A, create an AWS CloudFormation template that associates the privatehosted zone from Account B with the private hosted zone in Account A.
C. In Account A, use the AWS CLI to create a VPC association authorization. When theassociation is created, use the AWS CLI in Account B to associate the VPC from AccountA with the private hosted zone in Account B.
D. In Account B, use the AWS CLI to create a VPC association authorization. When the association is created, use the AWS CLI in Account A to associate the VPC from AccountB with the private hosted zone in Account A.
