Amazon DOP-C01 Practice Test - Questions Answers, Page 29

A development team manually builds an artifact locally and then places it in an Amazon S3 bucket. The application has a local cache that must be cleared when a deployment occurs. The team executes a command to do this, downloads the artifact from Amazon S3, and unzips the artifact to complete the deployment.

A DevOps team wants to migrate to a CI/CD process and build in checks to stop and roll back the deployment when a failure occurs. This requires the team to track the progression of the deployment. Which combination of actions will accomplish this? (Choose three.)

A web application has been deployed using an AWS Elastic Beanstalk application. The Application Developers are concerned that they are seeing high latency in two different areas of the application:

HTTP client requests to a third-party API

MySQL client library queries to an Amazon RDS database

A DevOps Engineer must gather trace data to diagnose the issues.

Which steps will gather the trace information with the LEAST amount of changes and performance impacts to the application?

An application is running on Amazon EC2. It has an attached IAM role that is receiving an AccessDenied error while trying to access a SecureString parameter resource in the AWS Systems Manager Parameter Store. The SecureString parameter is encrypted with a customer-managed Customer Master Key (CMK), What steps should the DevOps Engineer take to grant access to the role while granting least privilege? (Choose three.)

A company has an application that has predictable peak traffic times. The company wants the application instances to scale up only during the peak times. The application stores state in Amazon DynamoDB. The application environment uses a standard Node.js application stack and custom Chef recipes stored in a private Git repository. Which solution is MOST cost-effective and requires the LEAST amount of management overhead when performing rolling updates of the application environment?

A company has developed a Node.js web application which provides REST services to store and retrieve time series data. The web application is built by the Development team on company laptops, tested locally, and manually deployed to a single on-premises server, which accesses a local MySQL database. The company is starting a trial in two weeks, during which the application will undergo frequent updates based on customer feedback. The following requirements must be met:

The team must be able to reliably build, test, and deploy new updates on a daily basis, without downtime or degraded performance. The application must be able to scale to meet an unpredictable number of concurrent users during the trial. Which action will allow the team to quickly meet these objectives?

A company wants to use Amazon DynamoDB for maintaining metadata on its forums. See the sample data set in the image below.

A DevOps Engineer is required to define the table schema with the partition key, the sort key, the local secondary index, projected attributes, and fetch operations. The schema should support the following example searches using the least provisioned read capacity units to minimize cost.

-Search within ForumName for items where the subject starts with ‘a’.

-Search forums within the given LastPostDateTime time frame.

-Return the thread value where LastPostDateTime is within the last three months.

Which schema meets the requirements?

Some of your EC2 instances are configured to use a Proxy. Can you use Amazon Inspector for regular assessment of instances behind proxy?

A company is hosting a web application in an AWS Region. For disaster recovery purposes, a second region is being used as a standby. Disaster recovery requirements state that session data must be replicated between regions in near-real time and 1% of requests should route to the secondary region to continuously verify system functionality. Additionally, if there is a disruption in service in the main region, traffic should be automatically routed to the secondary region, and the secondary region must be able to scale up to handle all traffic. How should a DevOps Engineer meet these requirements?

What storage driver does Docker generally recommend that you use if it is available?
