A SysOps administrator is provisioning an Amazon Elastic File System (Amazon EFS) file system to provide shared storage across multiple Amazon EC2 instances. The instances all exist in the same VPC across multiple Availability Zones. There are two instances in each Availability Zone. The SysOps administrator must make the file system accessible to each instance with the lowest possible latency.
Which solution will meet these requirements?

A. Create a mount target for the EFS file system in the VPC. Use the mount target to mount the file system on each of the instances. B. Create a mount target for the EFS file system in one Availability Zone of the VPC. Use the mount target to mount the file system on the instances in that Availability Zone. Share the directory with the other instances. C. Create a mount target for each instance. Use each mount target to mount the EFS file system on each respective instance. D. Create a mount target in each Availability Zone of the VPC. Use the mount target to mount the EFS file system on the instances in the respective Availability Zone.

A SysOps administrator has successfully deployed a VPC with an AWS CloudFormation template. The SysOps administrator wants to deploy the same template across multiple accounts that are managed through AWS Organizations.
Which solution will meet this requirement with the LEAST operational overhead?

A. Assume the OrganizationAccountAccessRole IAM role from the management account. Deploy the template in each of the accounts. B. Create an AWS Lambda function to assume a role in each account. Deploy the template by using the AWS CloudFormation CreateStack API call. C. Create an AWS Lambda function to query for a list of accounts. Deploy the template by using the AWS CloudFormation CreateStack API call. D. Use AWS CloudFormation StackSets from the management account to deploy the template in each of the accounts.

A company is running distributed computing software to manage a fleet of 20 Amazon EC2 instances for calculations. The fleet includes 2 control nodes and 18 task nodes to run the calculations. Control nodes can automatically start the task nodes.
Currently, all the nodes run on demand. The control nodes must be available 24 hours a day, 7 days a week. The task nodes run for 4 hours each day. A SysOps administrator needs to optimize the cost of this solution.
Which combination of actions will meet these requirements? (Choose two.)

A. Purchase EC2 Instance Savings Plans for the control nodes. B. Use Dedicated Hosts for the control nodes. C. Use Reserved Instances for the task nodes. D. Use Spot Instances for the control nodes. Use On-Demand Instances if there is no Spot availability. E. Use Spot Instances for the task nodes. Use On-Demand Instances if there is no Spot availability.

A company is supposed to receive a data file every hour in an Amazon S3 bucket. An S3 event notification invokes an AWS Lambda function each time a file arrives. The function processes the data for use by an application.
The application team notices that sometimes the file does not arrive. The application team wants to receive a notification whenever the file does not arrive.
What is the MOST operationally efficient solution that meets these requirements?

A. Add an S3 Lifecycle rule on the S3 bucket with a scope that is limited to objects that were created in the last hour. Configure another S3 event notification to be invoked by the lifecycle transition when the number of objects transitioned is zero. Publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to notify the application team. B. Configure another S3 event notification to invoke a Lambda function that posts a message to an Amazon Simple Queue Service (Amazon SQS) queue. Create an Amazon CloudWatch alarm to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to notify the application team when the ApproximateAgeOfOldestMessage metric of the queue is greater than 1 hour. C. Create an Amazon CloudWatch alarm to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to alert the application team when the Invocations metric of the Lambda function is zero for an hour. Configure the alarm to treat missing data as breaching. D. Create a new Lambda function to get the timestamp of the newest file in the S3 bucket. If the timestamp is more than 1 hour ago, publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to notify the application team. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to invoke the new function hourly.

A company recently acquired another corporation and all of that corporation's AWS accounts. A financial analyst needs the cost data from these accounts. ASysOps administrator uses Cost Explorer to generate cost and usage reports. The SysOps administrator notices that "No Tagkey" represents 20% of the monthly cost.
What should the SysOps administrator do to tag the "No Tagkey" resources?

A. Add the accounts to AWS Organizations. Use a service control policy (SCP) to tag all the untagged resources. B. Use an AWS Config rule to find the untagged resources. Set the remediation action to terminate the resources. C. Use Cost Explorer to find and tag all the untagged resources. D. Use Tag Editor to find and tag all the untagged resources.

While setting up an AWS managed VPN connection, a SysOps administrator creates a customer gateway resource in AWS. The customer gateway device resides in a data center with a NAT gateway in front of it.
What address should be used to create the customer gateway resource?

A. The private IP address of the customer gateway device B. The MAC address of the NAT device in front of the customer gateway device C. The public IP address of the customer gateway device D. The public IP address of the NAT device in front of the customer gateway device

A company has a web application that is experiencing performance problems many times each night. A root cause analysis reveals sudden increases in CPU utilization that last 5 minutes on an Amazon EC2 Linux instance. A SysOps administrator must find the process ID (PID) of the service or process that is consuming more CPU.
What should the SysOps administrator do to collect the process utilization information with the LEAST amount of effort?

A. Configure the Amazon CloudWatch agent procstat plugin to capture CPU process metrics. B. Configure an AWS Lambda function to run every minute to capture the PID and send a notification. C. Log in to the EC2 instance by using a .pem key each night. Then run the top command. D. Use the default Amazon CloudWatch CPU utilization metric to capture the PID in CloudWatch.

A SysOps administrator configured AWS Backup to capture snapshots from a single Amazon EC2 instance that has one Amazon Elastic Block Store (AmazonEBS) volume attached. On the first snapshot, the EBS volume has 10 GiB of data. On the second snapshot, the EBS volume still contains 10 GiB of data, but 4GiB have changed. On the third snapshot, 2 GiB of data have been added to the volume, for a total of 12 GiB.
How much total storage is required to store these snapshots?

A. 12 GiB B. 16 GiB C. 26 GiB D. 32 GiB

A team is managing an AWS account that is a member of an organization in AWS Organizations. The organization has consolidated billing features enabled. The account hosts several applications.
A SysOps administrator has applied tags to resources within the account to reflect the environment. The team needs a report of the breakdown of charges by environment.
What should the SysOps administrator do to meet this requirement?

A. Filter, map, and categorize resource groups in Tag Editor. B. Ensure that the organization's service control policies (SCPs) allow access to cost al__cpLocation tags. C. Ensure that the IAM credentials that are used to access Cost Explorer have permissions to group cost by tags. D. Activate the tag keys for cost al__cpLocation on the organization's management account.

A company uses an AWS CloudFormation template to provision an Amazon EC2 instance and an Amazon RDS DB instance. A SysOps administrator must update the template to ensure that the DB instance is created before the EC2 instance is launched.
What should the SysOps administrator do to meet this requirement?

A. Add a wait condition to the template. Update the EC2 instance user data script to send a signal after the EC2 instance is started. B. Add the DependsOn attribute to the EC2 instance resource, and provide the logical name of the RDS resource. C. Change the order of the resources in the template so that the RDS resource is listed before the EC2 instance resource. D. Create multiple templates. Use AWS CloudFormation StackSets to wait for one stack to complete before the second stack is created.
