Scenario
The following four questions concern the Nexus 7010’s which are configured as a vPC pair at the core of a Data Center network. You can utilize all the available show commands to answer the questions. Access to the running-configuration is not allowed.
Instructions
Enter NX-OS commands on 7K-3 and 7K-4 to verify network operation and answer four multiple-choice questions.
THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.
Click on the switch to gain access to the console of the switch. No console or enable passwords are required.
To access the multiple-choice questions, click on the numbered boxes on the left of the top panel.
There are four multiple-choice questions with this task. Be sure to answer all four questions before selecting the Next button.
Within the vpc configuration of the 7K’s, the command peer-gateway is configured as confirmed with the command show vpc.
What is the result of enabling this command?
A. Enable 7k-3 to act as the active gateway for packet received on VLAN 101 that are addressed to the MAC address of 7k-4
B. Enables n7k-4 to use of the vpc peer link for forwarding packets received on VLAN 100 that are addressed to the MACRESS OF 7K-4
C. Generates IP redirect messages for packet switched though the peer-gateway router
D. Cause the HSRP active router to update the ARP table on the standby router for faster convergence after the vPC peer link has flapped
E. Allow the vpc peers to coordinate the IACP ID with must be the same on all links on all the port channel.
Should be A
The vPC peer-gateway functionality allows a vPC switch to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. This feature enables local forwarding of such packets without the need to cross the vPC peer-link. In this scenario, the feature optimizes use of the peer-link and avoids potential traffic loss.
