• Question 82:

  Which technology is responsible for matching a name to an IP address of an application running on a host?

  A. firewall
  B. proxy
  C. load balancer
  D. DNS
  D. DNS

  ---

  DNS (Domain Name System) is the technology responsible for matching a name to an IP address of an application running on a host. When a user types a domain name into a browser, DNS translates that domain name into the corresponding IP address, enabling the user's device to connect to the server hosting the application.

• Question 83:

  Into which type of Python data structure should common data formats be parsed?

  A. sequence
  B. set
  C. dictionary
  D. list
  C. dictionary

  ---

  JSON: JSON data can be parsed into a Python dictionary using the json.loads() function from the built-in json module. This function takes a JSON string as input and returns a dictionary representing the data.

• Question 84:

  Which tool is able to create a network design that simulates a topology?

  A. Docker
  B. pyATS
  C. Cisco DevNet Sandbox
  D. CML
  D. CML

  ---

  Cisco Modeling Labs (CML) is a tool that allows users to create network designs and simulate network topologies. It enables users to model complex network scenarios, test configurations, and simulate various networking conditions. CML is particularly useful for network design, testing, and validation before implementing changes in a production environment.

• Question 85:

  DRAG DROP

  Drag and drop the element of the Finesse API on the left onto the description of its functionality on the right.

  Select and Place:

• Question 86:

  Which network device plane is responsible for handling QoS?

  A. management plane
  B. data plane
  C. configuration plane
  D. control plane
  B. data plane

  ---

  The data plane, also known as the forwarding plane, is responsible for handling the actual movement of packets through the network device, including Quality of Service (QoS). QoS involves managing and prioritizing network traffic to ensure that critical applications receive the necessary bandwidth and performance levels. The data plane processes and forwards data packets based on the policies set by the control plane.

• Question 87:

  Which IP service is used to monitor the performance of network devices?

  A. SNMP
  B. DHCP
  C. DNS
  D. NTP
  A. SNMP

  ---

  Simple Network Management Protocol (SNMP) is widely used for network management and monitoring. It allows administrators to monitor and manage network devices such as routers, switches, and servers by collecting information on device performance, status, and errors. SNMP: Provides a framework for exchanging management information between network devices. It helps in monitoring network performance, detecting faults, and configuring devices remotely. Other Protocols: References: Cisco DevNet Associate Certification Guide Cisco SNMP Overview

• Question 88:

  Which tool simulates a network that runs Cisco equipment?

  A. Cisco Prime Infrastructure
  B. VMware
  C. Docker
  D. CML
  D. CML

  ---

  Explanation Explanation/Reference:Cisco Modeling Labs (CML) is a network simulation tool that allows users to create, configure, and simulate networks with Cisco devices and topologies. Cisco Modeling Labs (CML): CML provides a virtual environment where users can simulate network topologies and devices, including routers, switches, and other network components. Simulation and Testing: CML allows users to test configurations, troubleshoot network issues, and study network behavior in a controlled environment.

• Question 89:

  A developer prepares a Python application to monitor network performance on specific applications. The developer tests the code on a test environment but requires more use cases and wants the scripts to be improved for different networks. Which resource must be used to take advantage of open-source communities and contributors for the application?

  A. code exchange
  B. sandbox
  C. packet tracer
  D. learning labs
  A. code exchange

• Question 90:

  What are two principles of an infrastructure as code environment? (Choose two.)

  A. Components are coupled, and definitions must be deployed for the environment to function.
  B. Redeployments cause varying environment definitions.
  C. Environments must be provisioned consistently using the same inputs.
  D. Service overlap is encouraged to cater for unique environment needs.
  E. Complete complex systems must be able to be built from reusable infrastructure definitions.
  C. Environments must be provisioned consistently using the same inputs.
  E. Complete complex systems must be able to be built from reusable infrastructure definitions.
