   How can pyATS be used with Cisco Modeling Labs (CML) to automate testing?

   • ABy having pyATS connect to virtual devices in CML and run tests against them
   • BBy using pyATS to build topologies in CML
   • CBy using CML to generate test scripts for pyATS
   • DBy having CML execute pyATS test cases

   A network operations team wants to automatically verify that after every configuration change, all devices still have the expected routing table entries and that no interface is down. They plan to write Python scripts to perform these checks. Which tool should they use to structure these checks as reusable test cases?

   • ApyATS
   • BTerraform
   • CCML
   • DSNMP

   A pyATS user has written several test functions that verify BGP neighbor states, interface status, and routing table entries. They want to run all of these as a single logical unit and also be able to run them individually during debugging. How should they organize these test functions?

   • APut them in a single Job and use the --testcase option to run individual tests.
   • BDefine them as separate Testbeds.
   • CPlace them in a single Testcase and use the --test option to run individual tests.
   • DCreate a separate Job for each test function.

   A network engineer is writing a pyATS script to validate that a new ACL is correctly blocking traffic on a set of routers. The engineer wants the script to run the same verification steps on each router and produce a pass/fail report. Which pyATS concept should the engineer use to organize the verification steps?

   • AA job file that contains the ACL verification commands to be executed.
   • BA testcase that contains multiple test sections, each performing a specific verification step.
   • CA testbed file that defines the ACL configuration for each router.
   • DA single test section that runs all verification steps in one block.

   A network engineer is designing a CML lab to test a new OSPF implementation. The lab must include a mix of IOSv and IOS XE devices, and the engineer needs to ensure that the lab can be easily replicated for different test scenarios. The engineer also needs to manage the device images centrally. Which CML feature combination is most effective for this requirement?

   • AUse the CML API to manually configure each device and save the configuration.
   • BUse pyATS to define the topology and manage images.
   • CUse the CML GUI to manually build the lab each time.
   • DUse image management to upload and manage device images, and use topology templates to create reusable lab blueprints.
