Which AWS service meets the requirements?
A company has an application running on a fleet of Microsoft Windows instances. Patches to the operating system need to be applied each month. AWS Systems Manager Patch Manager is used to apply the patches on a schedule.
When the fleet is being patched, customers complain about delayed service responses.
What can be done to ensure patches are deployed with MINIMAL customer impact?
An organization has been running their website on several m2 Linux instances behind a Classic Load Balancer for more than two years. Traffic and utilization have been constant and predictable.
What should the organization do to reduce costs?

How can a SysOps administrator achieve this while maintaining the security of the application?
A sysops administrator must generate a report that provides a breakdown of all API activity by a specific user over the course of a year. AWS CloudTrail has already been enabled.
How should this report be generated?
A, Access the Cloud Trail logs stored in the Amazon S3 bucket tied to Cloud Trail. Use Amazon Athena to extract the information needed to generate the report
B. Locate the monthly reports that CloudTrail sends that are emailed to the account's root user. Forward the reports to the auditor using a secure channel
C. Use the AWS Management Console to search for the user name in the CloudTrail history. Filter by API and download the report in CSV format
D. Use the CloudTrail digest files stored in the company's Amazon S3 bucket. Send the logs to Amazon QuickSight to create the report.
A SysOps Administrator created an AWS CloudFormation template for the first time. The stack failed with a status of ROLLBACK_COMPLETE. The Administrator identified and resolved the template issue causing the failure.
How should the Administrator continue with the stack deployment?
An application running on Amazon EC2 allows users to launch batch jobs for data analysis. The jobs are run asynchronously, and the user is notified when they are complete. While multiple jobs can run concurrently, a user’s request need not be fulfilled for up to 24 hours. To run a job, the application launches an additional EC2 instance that performs all the analytics calculations. A job takes between 75 and 110 minutes to complete and cannot be interrupted.
What is the MOST cost-effective way to run this workload?
A SysOps Administrator must take a team’s single existing AWS CloudFormation template and split it into
smaller, service-specific templates. All of the services in the template reference a single, shared Amazon S3 bucket.
What should the Administrator do to ensure that this S3 bucket can be referenced by all the service
A SysOps Administrator created an Application Load balancer (ALB) and placed two Amazon EC2 instances in the same subnet behind the ALB. During monitoring, the Administrator observes HealthyHostCount drop to 1 in Amazon CloudWatch.
What is MOST likely causing this issue?
A company runs a web application that users access using the domain name www example com The company manages the domain name using Amazon Route 53 The company created an Amazon CloudFront distribution in front of the application and would like www example com to access the application through CloudFront
What is the MOST cost-effective way to achieve this?

What will be the result of this configuration?
An application running on Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones was deployed using an AWS CloudFormation template. A sysops administrator has patched the Amazon Machine Image (AMI) version and must update all the EC2 instances to use the new AMI.
How should Ihe administrator use CloudFormation to apply the new AMI while maintaining a minimum level of active instances to ensure service continuity?
A sysops administrator is creating two AWS Cloud Formation templates The first template will create a VPC with associated resources, such as subnets, route tables, and an internet gateway The second template will deploy application resources within the VPC that was created by the first template The second template should refer to the resources created by the first template
How can this be accomplished with the LEAST amount of administrative effort?
A SysOps administrator is maintaining an application running on Amazon EBS-backed Amazon EC2 instances in an Amazon EC2 Auto scaling group. The application is set to automatically terminate unhealthy instances. The administrator wants to preserve application logs from these instances for failure analysis.
Which action will accomplish this?
A SysOps Administrator is maintaining an application that runs on Amazon EC2 instances behind an application Load Balancer (ALB). Users are reporting errors when attempting to launch the application. The administrator notices an increase in the httpcode_ELS_5xx_Count Amazon CloudWatch metric for the load balancer.
What is the possible cause for this increase?
A web application runs on Amazon EC2 instances behind an ELB Application Load Balancer. The instances run in an EC2 Auto Scaling group across multiple Availability Zones. Amazon Route 53 is used for DNS and points to the load balancer. A SysOps Administrator has launched a new Auto Scaling group with a new version of the application, and wants to gradually shift traffic to the new version.
How can this be accomplished?
A user accidentally deleted a file from an Amazon EBS volume. The SysOps Administrator identified a recent snapshot for the volume.
What should the Administrator do to restore the user's file from the snapshot?
