Question 55

An engineer needs a standards-driven YANG model to manage a multivendor network environment. Which model should the engineer choose?

  • A: Native
  • B: OpenConfig
  • C: IETF
  • D: IEEE NETCONF

Question 56

Question 57

A router running ISIS is showing high CPU and bandwidth utilization. An engineer discovers that the router is configured as L1/L2 and has L1 and L2 neighbors.
Which step optimizes the design to address the issue?

  • A: Make this router a DIS for each of the interfaces
  • B: Disable the default behavior of advertising the default route on the L1/L2 router
  • C: Configure the router to be either L1 or L2
  • D: Configure each interface as either L1 or L2 circuit type

Question 58

A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?

  • A: Updates that contain changes within the data are sent only when changes occur.
  • B: Empty data subscriptions do not generate empty update notifications.
  • C: Periodic updates include a full copy of the data that is subscribed to.
  • D: The primary push update is sent immediately and cannot be delayed.

Question 59
