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?
Question 12
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?
Question 13
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.)
Question 14
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?
Question 15
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?
Question 16
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?
Question 17
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?
Question 18
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?
Question 19
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?
Question 20
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?
