NO.48 Each PC and IP phone in your network is connected to a switch using the same port. All incoming data traffic is untagged and belongs to the v10 VLAN, while traffic coming from the IP phones is tagged with a VLAN value of 20 and should belong to the v20 VLAN on your switch.
In this scenario, which statement is correct?

You must enable the voice VLAN feature on the incoming interfaces and assign the v20 VLAN.

Explanation
https://www.oreilly.com/library/view/juniper-mx-series/9781449358143/ch09s03.html The primary drawback to GR is the need for protocol extensions and helper support in neighboring routers, and a stable network topology. If any neighbors do not support GR, or if other changes occur in the network, GR ends up aborting and loss results in the dataplane. Even when all goes to plan and the GR event succeeds, which means there is zero loss in the data plane, there is still control plane flap and a subsequent need for protocol reconvergence between the restarting router and its helpers, …
