NEW QUESTION # 47
Which step must be taken to enable centralized logging in a Kubernetes environment?
- A. Deploy a sidecar node that aggregates logs from the entire cluster.
- B. Create a CustomResourceDefinition in each deployment that specifies the IP or names the log collector.
- C. No steps need to be taken. The master node automatically aggregates logs from all worker nodes and stores them on the specified persistent volume.
- D. Create a DaemonSet that deploys a container with a logging agent on every node in the cluster.
Answer: D
Explanation:
Explanation
To enable centralized logging in a Kubernetes environment, you must create a DaemonSet that deploys a container with a logging agent on every node in the cluster. This allows all of the logs from each node to be collected in one place, allowing for easier analysis and management. Reference: Kubernetes Documentation, Logging Architecture.

NEW QUESTION # 49
An application has been designed based on microservices. The application is deployed on Kubernetes using multiple pods that share the same IP address. Each pod is responsible for a service in the application.
Which command validates the success of the application deployment?
- A. kubectl rollout history deployment
- B. kubectl get pods -o wide -w
- C. kubectl describe pods/
- D. kubectl rollout status deployment
Answer: D
NEW QUESTION # 50
Which two practices help make the security of an application a more integral part of the software development lifecycle? (Choose two.)
- A. Add a step to the CI/CD pipeline that runs a static code analysis tool during the pipeline execution.
- B. Use only software modules that are written by the internal team.
- C. Ensure that the code repository server has enabled drive encryption and stores the keys on a Trusted Platform Module or Hardware Security Module.
- D. Add a step to the CI/CD pipeline that runs a dynamic code analysis tool during the pipeline execution.
- E. Add a step to the CI/CD pipeline to modify the release plan so that updated versions of the software are made available more often.
Answer: A,D
Explanation:
Adding a step to the CI/CD pipeline that runs a dynamic code analysis tool and a static code analysis tool during the pipeline execution helps make the security of an application a more integral part of the software development lifecycle. Dynamic code analysis tools search for coding errors and vulnerabilities while the application is running, while static code analysis tools scan the source code for potential errors and vulnerabilities. This ensures that any security issues are identified and addressed before the application is deployed. Additionally, using automated tools helps to reduce the amount of manual effort required for security testing and can reduce the risk of security flaws being introduced.

NEW QUESTION # 53
Refer to the exhibit.
What are the properties of the load balancer in a Kubernetes environment?
- A. Forwards any outgoing traffic from the port named nginx-port to exposed ports http-port1 and http-port2 of nginxapp
- B. Has exposed ports 80 and 8080 to a private IP address and directs outgoing connections to the port named http-port1
- C. Has exposed ports 80 and 8080 to a public IP address and directs incoming connections to the port named nginx-port
- D. Forwards incoming traffic from the port named nginx-port to ports 80 and 8080 of nginxapp
Answer: C
NEW QUESTION # 54
How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?
- A. All devices that generate syslogs must use agents that process the local logs and transmit them in a specific format to the ELK Stack.
- B. All logs are stored in their unstructured text format, and the ELK Stack performs data analysis by intelligently parsing the logs using machine learning algorithms.
- C. All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.
- D. A single, comprehensive log format is defined on the ELK Stack. All incoming logs, regardless of format, are transformed to match the comprehensive format, and only applicable fields are populated.
Answer: C
Explanation:
Explanation
The ELK Stack (Elasticsearch, Logstash, and Kibana) can handle ingesting unstructured logs from various devices in different formats by running custom filters on the logs. The filters are designed to parse the log data and extract the relevant, structured information from it, which is then stored for later analysis. This allows for faster and more accurate analysis of the data, and enables more sophisticated insights to be drawn from it.
