NEW QUESTION # 70
As a department starts following NetDevOps principles, how should the network monitoring strategy be updated to provide more visibility into the user experience?
- A. Update tools to pull or stream monitoring metrics from APIs instead of using legacy protocols
- B. Leverage machine learning tools to more quickly identify problems m syslog and SNMP data
- C. Identify and capture the key performance indicators that describe the state of the network
- D. Identify and fix network issues faster by leveraging streaming telemetry from network devices
Answer: A
Explanation:
Explanation
Updating tools to pull or stream monitoring metrics from APIs instead of using legacy protocols is an important part of a NetDevOps strategy, as it allows for more efficient and automated data collection, as well as better visibility into the user experience. APIs for network monitoring are becoming increasingly common, as they allow for a more direct connection to the devices themselves, and can provide access to more detailed and specific metrics. Cisco's DevOps Solutions and Practices Guide recommends leveraging APIs to monitor the user experience, as they can provide access to more specific metrics and can be integrated with other monitoring tools.
NEW QUESTION # 71

NEW QUESTION # 72
What is as responsibility for teams running private cloud servers that is less of a concern when running in the public cloud?
- A. credentials management
- B. hardware maintenance
- C. cost
- D. metrics and monitoring
Answer: A
Explanation:
Explanation
The responsibility of credentials management is less of a concern when running in the public cloud. This is because the public cloud provider typically manages the credentials and handles authentication and authorization for the cloud services. In a private cloud environment, the organization must manage the credentials themselves, as well as authentication and authorization for the cloud services.

NEW QUESTION # 74
Which two practices help make the security of an application a more integral part of the software development lifecycle? (Choose two.)
- A. Use only software modules that are written by the internal team.
- B. Add a step to the CI/CD pipeline that runs a static code analysis tool during the pipeline execution.
- C. 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.
- D. Ensure that the code repository server has enabled drive encryption and stores the keys on a Trusted Platform Module or Hardware Security Module.
- E. Add a step to the CI/CD pipeline that runs a dynamic code analysis tool during the pipeline execution.
Answer: B,E
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 # 75
A development team uses Kubernetes for application development. Any changes on ConfigMap are performed manually for each development, test, and production environment. The edits are performed to deploy applications. This approach causes inconsistent deployments across all environments.
Which practice improves the consistency of the deployments?
- A. Generate the ConfigMaps specific to the environment by using a templating language such as Jinja2 and store the ConfigMaps in unique branches of a repository
- B. Create a unique repository for each environment that contains ConfigMaps for that environment to ensure that each environment can be deployed independently
- C. Implement environment variables within the ConfigMaps and store the variable definitions separately from the master branch where the ConfigMaps are stored
- D. In the master branch where the ConfigMaps are stored, create a branch for each environment that contains an environment-specific ConfigMap.
Answer: C
NEW QUESTION # 76
Which interface is most commonly used to integrate logging, monitoring, and alerting applications into your CI/ CD pipeline?
- A. REST
- B. SNMP
- C. AMQP
- D. SSH
Answer: A
Explanation:
Explanation
The most commonly used interface to integrate logging, monitoring, and alerting applications into your CI/CD pipeline is REST. Representational State Transfer (REST) is an architectural style that defines a set of constraints and properties based on HTTP. It enables developers to create APIs that are easy to use and access, and is well-suited for integrating logging, monitoring, and alerting applications into your CI/CD pipeline.

NEW QUESTION # 79
A developer has created a deployment that should launch a pod to run their database service. The pod should launch with a metadata name of "Cisco-DB," and the developer has added it to the "Cisco" namespace in their deployment.
Which Kubernetes command confirms that the service is running and usable?
- A. kubectl -n Cisco get services | grep "Cisco-DB"
- B. kubectl get pods | grep "Cisco-DB"
- C. kubectl -n Cisco get pods | grep "Cisco-DB"
- D. kubectl -n Cisco get service | grep "Cisco-DB"
Answer: C
Explanation:
Explanation
The correct answer is B. kubectl -n Cisco get pods | grep "Cisco-DB". This command allows you to view the pods in the Cisco namespace and filter the list for the pod named "Cisco-DB". This will confirm that the pod is running and usable.
