Which two statements are correct about repairing a Juniper Apstra cabling map before deploying your blueprint? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: B, C

The cabling map is a graphical representation of the physical connections between the devices in the data center fabric. It shows the status of the cables, interfaces, and BGP sessions for each device. You can use the cabling map to verify and repair the cabling before deploying your blueprint. Based on the web search results, we can infer the following statements:

Apstra can use LLDP data from the spine-to-leaf fabric devices to update the connections in the cabling map.This is true because Apstra can collect LLDP data from the devices using the Generic Graph Collector processor and use it to update the cabling map automatically.LLDP is a protocol that allows devices to exchange information about their identity, capabilities, and neighbors12.

Apstra can use LLDP data from the leaf devices to update the leaf-to-generic connections in the cabling map.This is true because Apstra can also collect LLDP data from the leaf devices and use it to update the connections to the generic devices, such as routers, firewalls, or servers.Generic devices are devices that are not managed by Apstra but are part of the data center fabric23.

You must manually change the cabling map to update spine-to-leaf fabric links.This is false because Apstra can use LLDP data to update the spine-to-leaf fabric links automatically, as explained above.However, you can also manually change the cabling map to override the Apstra-generated cabling, if needed24.

You must manually change the cabling map to update leaf-to-generic links.This is false because Apstra can use LLDP data to update the leaf-to-generic links automatically, as explained above.However, you can also manually change the cabling map to override the Apstra-generated cabling, if needed24.Reference:

I'm not sure about option A and D, do we really need to manually change the cabling map for those links?

I believe option C is also correct, Apstra can use LLDP data from the leaf devices.
