A company is using Amazon CloudFront to serve static content for its web application to its users. The CloudFront distribution uses an existing on-premises website as a custom origin.
The company requires the use of TLS between CloudFront and the origin server. This configuration has worked as expected for several months. However, users are now experiencing HTTP 502 (Bad Gateway) errors when they view webpages that include content from the CloudFront distribution.
What should a SysOps administrator do to resolve this problem?
A
An Amazon CloudFront distribution has a single Amazon S3 bucket as its origin. A SysOps administrator must ensure that users can access the S3 bucket only through requests from the CloudFront endpoint.
Which solution will meet these requirements?
C
A SysOps administrator is designing a solution for an Amazon RDS for PostgreSQL DB instance. Database credentials must be stored and rotated monthly. The applications that connect to the DB instance send write-intensive traffic with variable client connections that sometimes increase significantly in a short period of time.
Which solution should a SysOps administrator choose to meet these requirements?
C
A company wants to reduce costs for jobs that can be completed at any time. The jobs currently run by using multiple Amazon EC2 On-Demand Instances and the jobs take slightly less than 2 hours to complete. If a job falls for any reason it must be restarted from the beginning.
Which solution will meet these requirements MOST cost-effectively?
C
An environment consists of 100 Amazon EC2 Windows instances. The Amazon CloudWatch agent is deployed and running on all EC2 Instances with a baseline configuration file to capture log files. There is a new requirement to capture the DHCP log files that exist on 50 of the instances.
What is the MOST operationally efficient way to meet this new requirement?
D
A company has 10 Amazon EC2 instances in its production account. A SysOps administrator must ensure that email notifications are sent to administrators each time there is an EC2 instance state change.
Which solution will meet this requirements?
C
A company has an application that runs on a fleet of Amazon EC2 instances behind an Elastic Load Balancer. The instances run in an Auto Scaling group. The application's performance remains consistent throughout most of each day. However, an increase in user traffic slows the performance during the same 4-hour period of time each day.
What is the MOST operationally efficient solution that will resolve this issue?
A
A company hosts an application on an Amazon EC2 instance in a single AWS Region. The application requires support for non-HTTP TCP traffic and HTTP traffic.
The company wants to deliver content with low latency by leveraging the AWS network. The company also wants to implement an Auto Scaling group with an
Elastic Load Balancer.
How should a SysOps administrator meet these requirements?
B
A SysOps administrator has an AWS CloudFormation template that is used to deploy an encrypted Amazon Machine Image (AMI). The CloudFormation template will be used in a second account so the SysOps administrator copies the encrypted AMI to the second account. When launching the new CloudFormation stack in the second account, it fails.
Which action should the SysOps administrator take to correct the issue?
C
A company’s SysOps administrator deploys four new Amazon EC2 instances by using the standard Amazon Linux 2 Amazon Machine Image (AMI). The company needs to be able to use AWS Systems Manager to manage the instances. The SysOps administrator notices that the instances do not appear in the Systems Manager console.
What must the SysOps administrator do to resolve this issue?
D
