- B: 4-class model
- C: 6-class model
- D: 12-class model

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.
