Amazon AWS Certified DevOps Engineer - Professional DOP-C02 Prüfungsfragen mit Lösungen (Q152-Q157):

152. Frage
A company hired a penetration tester to simulate an internal security breach The tester performed port scans on the company's Amazon EC2 instances. The company's security measures did not detect the port scans.
The company needs a solution that automatically provides notification when port scans are performed on EC2 instances. The company creates and subscribes to an Amazon Simple Notification Service (Amazon SNS) topic.
What should the company do next to meet the requirement?

Antwort: D

Begründung:
* Ensure that Amazon GuardDuty is Enabled:
Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior.
It can detect port scans and generate findings for these events.
* Create an Amazon CloudWatch Alarm for Detected EC2 and Port Scan Findings:
Configure GuardDuty to monitor for port scans and other threats.
Create a CloudWatch alarm that triggers when GuardDuty detects port scan activities.
* Connect the Alarm to the SNS Topic:
The CloudWatch alarm should be configured to send notifications to the SNS topic subscribed by the security team.
This setup ensures that the security team receives near-real-time notifications when a port scan is detected on the EC2 instances.
Example configuration steps:
Enable GuardDuty and ensure it is monitoring the relevant AWS accounts.
Create a CloudWatch alarm:
{
"AlarmName": "GuardDutyPortScanAlarm",
"MetricName": "ThreatIntelIndicator",
"Namespace": "AWS/GuardDuty",
"Statistic": "Sum",
"Dimensions": [
{
"Name": "FindingType",
"Value": "Recon:EC2/Portscan"
}
],
"Period": 300,
"EvaluationPeriods": 1,
"Threshold": 1,
"ComparisonOperator": "GreaterThanOrEqualToThreshold",
"AlarmActions": ["arn:aws:sns:region:account-id:SecurityAlerts"]
}

153. Frage
A company wants to use a grid system for a proprietary enterprise m-memory data store on top of AWS. This system can run in multiple server nodes in any Linux-based distribution. The system must be able to reconfigure the entire cluster every time a node is added or removed. When adding or removing nodes an /etc.
/cluster/nodes config file must be updated listing the IP addresses of the current node members of that cluster.
The company wants to automate the task of adding new nodes to a cluster.
Whatcan a DevOps engineer do to meet these requirements?

Antwort: D

Begründung:
You can run custom recipes manually, but the best approach is usually to have AWS OpsWorks Stacks run them automatically. Every layer has a set of built-in recipes assigned each of five lifecycle events-Setup, Configure, Deploy, Undeploy, and Shutdown. Each time an event occurs for an instance, AWS OpsWorks Stacks runs the associated recipes for each of the instance's layers, which handle the corresponding tasks. For example, when an instance finishes booting, AWS OpsWorks Stacks triggers a Setup event. This event runs the associated layer's Setup recipes, which typically handle tasks such as installing and configuring packages


154. Frage
A company wants to set up a continuous delivery pipeline. The company stores application code in a private GitHub repository. The company needs to deploy the application components to Amazon Elastic Container Service (Amazon ECS). Amazon EC2, and AWS Lambd a. The pipeline must support manual approval actions.
Which solution will meet these requirements?

Antwort: A


155. Frage
A company has multiple AWS accounts. The company uses AWS IAM Identity Center (AWS Single Sign- On) that is integrated with AWS Toolkit for Microsoft Azure DevOps. The attributes for access control feature is enabled in IAM Identity Center.
The attribute mapping list contains two entries. The department key is mapped to ${path:enterprise.
department}. The costCenter key is mapped to ${path:enterprise.costCenter}.
All existing Amazon EC2 instances have a department tag that corresponds to three company departments (d1, d2, d3). A DevOps engineer must create policies based on the matching attributes. The policies must minimize administrative effort and must grant each Azure AD user access to only the EC2 instances that are tagged with the user's respective department name.
Which condition key should the DevOps engineer include in the custom permissions policies to meet these requirements?

Antwort: D

Begründung:
https://docs.aws.amazon.com/singlesignon/latest/userguide/configure-abac.html


156. Frage
A company's application is currently deployed to a single AWS Region. Recently, the company opened a new office on a different continent. The users in the new office are experiencing high latency. The company's application runs on Amazon EC2 instances behind an Application Load Balancer (ALB) and uses Amazon DynamoDB as the database layer. The instances run in an EC2 Auto Scaling group across multiple Availability Zones. A DevOps engineer is tasked with minimizing application response times and improving availability for users in both Regions.
Which combination of actions should be taken to address the latency issues? (Choose three.)

Antwort: B,D,E

Begründung:
C) Create new ALB and Auto Scaling group resources in the new Region and configure the new ALB to direct traffic to the new Auto Scaling group. This will allow users in the new Region to access the application with lower latency by reducing the network hops between the user and the application servers.
D) Create Amazon Route 53 records, health checks, and latency-based routing policies to route to the ALB. This will enable Route 53 to route user traffic to the nearest healthy ALB, based on the latency between the user and the ALBs.
F) Convert the DynamoDB table to a global table. This will enable reads and writes to the table in both Regions with low latency, improving the overall response time of the application
