The correct answer is D. The link carries VRRP messages between the VRRP Master and Backup on all VLANs. VRRP advertisement packets are exchanged on the link between the two Core switches. This link is veryimportant and a failure can lead to a VLAN that is cut into 2 parts which will cause communication disruption.So, it is recommended to configure a trunk of 2 links or more…
Question
A company campus LAN requires high availability, so all edge switches have redundant links to the core. As part of the high availability design, all switches implement Multiple Spanning Tree Protocol (MSTP), and the core switches implement Virtual Router Redundancy Protocol (VRRP). Protocols are implemented to use links in the most efficient manner. What is the purpose of the link between the core switches during normal operation (when all links are up)?
Options
- AThe link acts as a backup link, blocked by MSTP in each instance but ready to transition to the forwarding
- BThe link carries any traffic that arrives on the VRRP Backup to the VRRP Master.
- CThe link does not carry any traffic but remains in forwarding state, ready to act as a backup in case another
- DThe link carries VRRP messages between the VRRP Master and Backup on all VLANs.

Explanation
VRRP advertisement packets are exchanged on the link between the two Core switches. This link is veryimportant and a failure can lead to a VLAN that is cut into 2 parts which will cause communication disruption.So, it is recommended to configure a trunk of 2 links or more between the two Core switches for better redundancy
