Q59. How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?

All devices that generate syslogs must use agents that process the local logs and transmit them in a specific format to the ELK Stack.

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.

All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.

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.

Q60. Drag and drop the commands from the bottom onto the correct Terraform code in the exhibit to push a network object to a Cisco ASA Firewall device.

Q61. Fill in the blanks to complete the line of Python code that sends a message to a Webex Teams room or person.

Q62. Which two actions help limit the attack surface of your Docker container? (Choose two.)

Run only a single service in each container.

Run all services in a single image.

Use version tags for base images and dependencies.

Use Kali Linux as a base image.

Download images over HTTPS supporting sites.

Running only a single service in each container and using version tags for base images and dependencies helps limit the attack surface of your Docker container. This ensures that only the necessary services are running and that you always have the latest versions of the base images and their dependencies, reducing the risk of malicious code being included in the container image. Reference: Docker Documentation, Security Best Practices.

Q63. A developer is nearing the end of a software development cycle and is ready to deploy the software. The customer wants to continue using a secure software development lifecycle methodology and must plan for postproduction components. Which two areas should be the developer address? (Choose two.)

Q66. Configuration changes to the production network devices are performed by a CI/CD pipeline. The code repository and the CI tool are running on separate servers. Some configuration changes are pushed to the code repository, but the pipeline did not start.
Why did the pipeline fail to start?

The pipeline must be started manually after the code repository is updated.

The CI server was not configured as a Git remote for the repository.

The webhook call from the code repository did not reach the CI server.

Configuration changes must be sent to the pipeline, which then updates the repository.

Explanation
A webhook is basically a callback URL that is triggered when certain events occur, such as a code commit. If the webhook call from the code repository does not reach the CI server, then the pipeline will not start.
According to the Cisco Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, “A webhook is a web-based feature that enables a remote service to communicate with a local service, usually through a web server. Webhooks are used to trigger an action when a specific event occurs, usually in a remote service or application.”

Q67. An organization is developing an application using Git. Each team member is assigned to work on specific parts of the application. At the end of each task, individual code parts are merged in the main build.
Which two requirements should be implemented to increase the likelihood of continuous integration? (Choose two.)

Changes must include automated tests

Changes must be scheduled to deploy at a specific time that has minimal traffic

Changes must be validated during deployment to the production environment

Team members must be responsible for the code committed by any team member

Smaller, individually testable changes must be merged first

Q68. What is chaos engineering?

designing an application with fuzzy logic that makes it hard to predict

a product engineering approach that lacks a formal methodology

splitting a project between teams that do not communicate with each other

introducing problems into a system to study behavior and improve reliability

Section: Logging, Monitoring, and Metrics

Q69. Which type of security testing should be performed as a part of a CI/CD pipeline by analyzing the source code itself without compiling the code into a running executable?

Dynamic Application Security Testing

Runtime Application Health-Protection

Continuous Application Security Testing

Static Analysis Security Testing

Q70. As a department starts following NetDevOps principles, how should the network monitoring strategy be updated to provide more visibility into the user experience?

Update tools to pull or stream monitoring metrics from APIs instead of using legacy protocols

Identify and capture the key performance indicators that describe the state of the network

Identify and fix network issues faster by leveraging streaming telemetry from network devices

Leverage machine learning tools to more quickly identify problems m syslog and SNMP data

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.

Q71.

Refer to the exhibit. A developer is creating a health check monitoring script that queries information from the Cisco DNA Center platform. The script must trigger an alert if a site health statistic named accessGoodCount drops below 80 and if a network statistic named latestHealthScore is 95 or less.
Drag and drop the code snippets from the bottom onto the blanks in the code to monitor the site and network health on a Cisco DNA Center platform instance. Options may be used more than once. Not all options are used.

Explanation
1. ‘timestamp’
2. url = BASE_URL + SITE_HEALTH
3. params
4. url = BASE_URL + NETWORK_HEALTH_URL
5. params

Q72. Refer to the exhibit.

What are the properties of the load balancer in a Kubernetes environment?

TextMessage -> Alter Base

Q79. A company has a CI/CD pipeline implemented to automate application deployment. An urgent change is required in the production environment. A developer produces and tests the required change in the company’s environment, but the pipeline fails when pushed.
Which action conforms to the rules of a CI/CD pipeline and enables the pipeline to pass?

Remove the failing test.

Manually deploy the change into the production environment

Use a backup pipeline

Replicate the production environment in the pipeline before applying

This ensures that the change is applied in the same environment that it was tested in, and that the pipeline will pass. This is in accordance with the rule of a CI/CD pipeline that states that the same environment should be used for testing and deploying code into production. As stated in the Cisco Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, “the same environment should be used for testing and deploying code into production, or the pipeline will fail.”

Q80. A DevOps engineer must build a Docker image to containerize an application. Then the image must be pushed to a repository on Docker Hub in a CI/CD pipeline using GitHub Actions.
