After launching a new Amazon EC2 instance from a Microsoft Windows 2012 Amazon Machine Image (AMI), the SysOps Administrator is unable to connect to the instance using Remote Desktop Protocol (RDP). The instance is also unreachable. As part of troubleshooting, the Administrator deploys a second instance from a different AMI using the same configuration and is able to connect to the instance.
What should be the next logical step in troubleshooting the first instance?
  • A. Use AWS Trusted Advisor to gather operating system log files for analysis.
  • B. Use VPC Flow Logs to gather operating system log files for analysis.
  • C. Use EC2Rescue to gather operating system log files for analysis.
  • D. Use Amazon Inspector to gather operating system log files for analysis.

An organization has decided to consolidate storage and move all of its backups and archives to Amazon S3. With all of the data gathered into a hierarchy under a single directory, the organization determines there is 70 TB of data that needs to be uploaded. The organization currently has a 150-Mbps connection with 10 people working at the location.
Which service would be the MOST efficient way to transfer this data to Amazon S3?
  • A. AWS Snowball
  • B. AWS Direct Connect
  • C. AWS Storage Gateway
  • D. Amazon S3 Transfer Acceleration

A SysOps Administrator is running an automatically scaled application behind an Application Load Balancer. Scaling out is triggered when the CPUUtilization instance metric is more than 75% across the Auto Scaling group. The Administrator noticed aggressive scaling out. Developers suspect an application memory leak that is causing aggressive garbage collection cycles.
How can the Administrator troubleshoot the application without triggering the scaling process?
  • A. Suspend the scaling process before troubleshooting.
  • B. Delete the Auto Scaling group and recreate it when troubleshooting is complete.
  • C. Remove impacted instances from the Application Load Balancer.
  • D. Create a scale down trigger when the CPUUtilization instance metric is at 70%.

A company has two AWS accounts: development and production. All applications send logs to a specific Amazon S3 bucket for each account, and the Developers are requesting access to the production account S3 buckets to view the logs.
Which is the MOST efficient way to provide the Developers with access?
  • A. Create an AWS Lambda function with an IAM role attached to it that has access to both accounts' S3 buckets. Pull the logs from the production S3 bucket to the development S3 bucket.
  • B. Create IAM users for each Developer on the production account, and add the Developers to an IAM group that provides read-only access to the S3 log bucket.
  • C. Create an Amazon EC2 bastion host with an IAM role attached to it that has access to the production S3 log bucket, and then provision access for the Developers on the host.
  • D. Create a resource-based policy for the S3 bucket on the production account that grants access to the development account, and then delegate access in the development account.

An application accesses data through a file system interface. The application runs on Amazon EC2 instances in multiple Availability Zones, all of which must share the same data. While the amount of data is currently small, the company anticipates that it will grow to tens of terabytes over the lifetime of the application.
What is the MOST scalable storage solution to fulfill the requirement?
  • A. Connect a large Amazon EBS volume to multiple instances and schedule snapshots.
  • B. Deploy Amazon EFS is in the VPC and create mount targets in multiple subnets.
  • C. Launch an EC2 instance and share data using SMB/CIFS or NFS.
  • D. Deploy an AWS Storage Gateway cached volume on Amazon EC2.

A SysOps Administrator has been tasked with deploying a company's infrastructure as code. The Administrator wants to write a single template that can be reused for multiple environments in a safe, repeatable manner.
What is the recommended way to use AWS CloudFormation to meet this requirement?
  • A. Use parameters to provision the resources.
  • B. Use nested stacks to provision the resources.
  • C. Use Amazon EC2 user data to provision the resources.
  • D. Use stack policies to provision the resources.

The Security team has decided that there will be no public internet access to HTTP (TCP port 80) because it is moving to HTTPS for all incoming web traffic. The team has asked a SysOps Administrator to provide a report on any security groups that are not compliant.
What should the SysOps Administrator do to provide near real-time compliance reporting?
  • A. Enable AWS Trusted Advisor and show the Security team that the Security Groups unrestricted access check will alarm.
  • B. Schedule an AWS Lambda function to run hourly to scan and evaluate all security groups, and send a report to the Security team.
  • C. Use AWS Config to enable the restricted-common-ports rule, and add port 80 to the parameters.
  • D. Use Amazon Inspector to evaluate the security groups during scans, and send the completed reports to the Security team.

An e-commerce company wants to lower costs on its nightly jobs that aggregate the current day's sales and store the results in Amazon S3. The jobs are currently run using multiple on-demand instances and the jobs take just under 2 hours to complete. If a job fails for any reason, it needs to be restarted from the beginning.
What method is the MOST cost effective based on these requirements?
  • A. Use a mixture of On-Demand and Spot Instances for job execution.
  • B. Submit a request for a Spot block to be used for job execution.
  • C. Purchase Reserved Instances to be used for job execution.
  • D. Submit a request for a one-time Spot Instance for job execution.
