Refer to the exhibit.
You configure a vPC between two Cisco Nexus 7000 Series switches but the peer link will not come up. What is the problem?
A. The system priority must be the same.
B. The configuration is correct. The problem lies elsewhere.
C. The role priority must be the same.
D. The vPC domain numbers must be different.
Answer is A
You should manually configure the vPC system priority when you are running Link Aggregation Control Protocol (LACP) to help ensure that the vPC peer devices are the primary devices on LACP. When you manually configure the system priority, make sure that you configure the same priority value on both vPC peer devices. If these values do not match, vPC will not be activated.
