Cisco 300-910 Online Questions & Answers

• Question 61:

  When static routes are added to a router in a network using a CI/CD pipeline, an Ansible playbook is used to make these changes. Which steps must be added to the pipeline to validate that the changes have the intended effect on the traffic flow?

  A. Add a step to run the debug ip routing command before the change, and add a step after the change to issue the no debug ip routing command.
  B. Add a step to capture the routing table before the change, and add a step after the change to capture it again. Calculate the difference between the two for review.
  C. Add a step to ping a host on each of the static routes before the change, and a step after to repeat the same check. Calculate the difference between the two checks for review.
  D. Add a step to run the same playbook again with the debug option enabled and use grep on the log output to ensure that the commands are not applied again.
  B. Add a step to capture the routing table before the change, and add a step after the change to capture it again. Calculate the difference between the two for review.

• Question 62:

  Microservices architecture pattern has been applied and the system has been architected as a set of services. Each service is deployed as a set of instances for throughput and availability.

  In which two ways are these services packaged and deployed? (Choose two.)

  A. Service instances must be isolated from one another.
  B. Service must be independently deployable and scalable.
  C. Service are written using the same languages, frameworks, and framework versions.
  D. Service must be dependent, deployable, and scalable.
  E. Service instances do not need to be isolated from one another.
  A. Service instances must be isolated from one another.
  B. Service must be independently deployable and scalable.

• Question 63:

  DRAG DROP

  The IaC configuration for an application is being deployed using a CI/CD pipeline. Drag and drop the steps for this pipeline from the left into the correct order that they would be executed on the right. Not all options are used.

  Select and Place:

  

  

• Question 64:

  DRAG DROP

  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.

  Select and Place:

  

  

• Question 65:

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

  A. Run only a single service in each container.
  B. Run all services in a single image.
  C. Use version tags for base images and dependencies.
  D. Use Kali Linux as a base image.
  E. Download images over HTTPS supporting sites.
  A. Run only a single service in each container.
  C. Use version tags for base images and dependencies.

  ---

  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.

• Question 66:

  DRAG DROP

  Refer to the exhibit.

  

  A development team is designing an application that will include multiple components and services. To streamline the process, CO/CD must be implemented. Drag and drop the CI/CD pipeline stages from the left onto the targets on the right.

  Select and Place:

  

  

• Question 67:

  Which interface is most commonly used to integrate logging, monitoring, and alerting applications into your CI/CD pipeline?

  A. AMQP
  B. SNMP
  C. SSH
  D. REST
  D. REST

  ---

  Explanation Explanation/Reference: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.

• Question 68:

  FILL BLANK Fill in the blanks to describe the concepts of extending DevOps practices to the network for NetDevOps. NetDevOps builds and manages networks as a system that enables network services to be consumed in a DevOps approach. Organizations practicing NetDevOps see changes in the _________ as routine and expected activities, with a well-

  defined and practiced process for _________ , testing, and __________ network changes. By making them routine, network changes can be small and simple.

• Question 69:

  Refer to the exhibit.

  

  How does the architecture respond to a usage spike?

  A. The monitoring software instructs the Orchestrator to increase the count of containers and to configure the load balancer accordingly
  B. The database prioritizes quick and immediate queries over complicated ones to reduce the request queue
  C. The Orchestrator increases the resources assigned to containers to increase performance
  D. The load balancer interacts with the Orchestrator to optimize the balancing algorithm to match the incoming flow of requests
  D. The load balancer interacts with the Orchestrator to optimize the balancing algorithm to match the incoming flow of requests

• Question 70:

  Refer to the exhibit.

  

  An application has been developed as a fileserver. To create this application as a fileserver. the class is used to store data in an SQL database.

  Which two steps help minimize the risk of attack and compromise of the application? (Choose two.)

  A. Reject string values that are greater than maximum size
  B. Use floating point instead of integer for rating to avoid overflow
  C. Validate the content of the name and address parameters
  D. Run the application in a Docker container
  E. Compile the application using Java HotSpot
  A. Reject string values that are greater than maximum size
  C. Validate the content of the name and address parameters
