NEW QUESTION 38
Drag and drop the characteristics from the left onto the correct telemetry mode on the right.
Answer:
Explanation:
In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription. All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.

NEW QUESTION 39
Which statement describes what happens if all VSL connections between the virtual switch members are lost?
- A. The virtual switch members reload.
- B. The VSS transitions to the dual active recovery mode, and only the new active virtual switch continues to forward traffic.
- C. The VSS transitions to the dual active recovery mode, and both virtual switch members continue to forward traffic independently.
- D. Both virtual switch members cease to forward traffic.
Answer: B
Explanation:
Q. What happens if all VSL connections between the virtual switch members are lost?
A. VSLs can be configured with up to eight links between the two switches across any combination of line cards or supervisor ports to provide a high level of redundancy. If for some rare reason all VSL connections are lost between the virtual switch members leaving both the virtual switch members up, the VSS will transition to the dual active recovery mode.
The dual active state is detected rapidly (subsecond) by any of the following three methods:
Enhancement to PagP used in MEC with connecting Cisco switches
L3 Bidirectional Forwarding Detection (BFD) configuration on a directly connected link (besides VSL) between virtual switch members or through an L2 link through an access layer switch L2 Fast-Hello Dual-Active Detection configuration on a directly connected link (besides VSL) between virtual switch members (supported with 12.2(33)SXI) In the dual active recovery mode, all interfaces except the VSL interfaces are in an operationally shut down state in the formerly active virtual switch member. The new active virtual switch continues to forward traffic on all links.

- B. Use OSPF with a passive-interface command on the backup connection.
- C. Use static routes tied to an IP SLA to prefer the primary path while a floating static route points to the backup connection.
