An organization is running multiple applications for their customers. Each application is
deployed by running a base AWS CloudFormation template that configures a new VPC. All
applications are run in the same AWS account and AWS Region. A SysOps administrator
has noticed that when trying to deploy the same AWS
CloudFormation stack, it fails to deploy.
What is likely to be the problem?
A.
The Amazon Machine image used is not available in that region.
B.
The AWS CloudFormation template needs to be updated to the latest version.
C.
The VPC configuration parameters have changed and must be updated in the template.
D.
The account has reached the default limit for VPCs allowed.
The account has reached the default limit for VPCs allowed.
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 this requirement?
A.
Connect a large Amazon EBS volume to multiple instances and schedule snapshots.
B.
Deploy Amazon EFS 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.
Deploy Amazon EFS in the VPC and create mount targets in multiple subnets.
A company has a stateless application that is hosted on a fleet of 10 Amazon EC2 On- Demand Instances in an Auto Scaling group. A minimum of 6 instances are needed to meet service requirements. Which action will maintain uptime for the application MOST cost-effectively?
A.
Use a Spot Fleet with an On-Demand capacity of 6 instances.
B.
Update the Auto Scaling group with a minimum of 6 On-Demand Instances and a maximum of 10 On-Demand Instances.
C.
Update the Auto Scaling group with a minimum of 1 On-Demand Instance and a maximum of 6 On-Demand Instances.
D.
Use a Spot Fleet with a target capacity of 6 instances
Use a Spot Fleet with an On-Demand capacity of 6 instances.
A SysOps administrator is deploying an application on 10 Amazon EC2 instances. The application must be highly available. The instances must be placed on distinct underlying hardware. What should the SysOps administrator do to meet these requirements?
A.
Launch the instances into a cluster placement group in a single AWS Region.
B.
Launch the instances into a partition placement group in multiple AWS Regions.
C.
Launch the instances into a spread placement group in multiple AWS Regions.
D.
Launch the instances into a spread placement group in single AWS Region
Launch the instances into a spread placement group in single AWS Region

A company is testing Amazon Elasticsearch Service (Amazon ES) as a solution for analyzing system logs from a fleet of Amazon EC2 instances. During the test phase, the domain operates on a single-node cluster. A SysOps administrator needs to transition the test domain into a highly available production-grade deployment. Which Amazon ES configuration should the SysOps administrator use to meet this requirement?
A.
Use a cluster of four data nodes across two AWS Regions. Deploy four dedicated master nodes in each Region.
B.
Use a cluster of six data nodes across three Availability Zones. Use three dedicated master nodes.
C.
Use a cluster of six data nodes across three Availability Zones. Use six dedicated master nodes.
D.
Use a cluster of eight data nodes across two Availability Zones. Deploy four master nodes in a failover AWS Region.
Use a cluster of six data nodes across three Availability Zones. Use three dedicated master nodes.
