Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 461
An engineer must configure two Cisco Nexus 7000 Series switches in the same data center to support OTV. Which command set completes the join interface configuration? feature otv otv site-identifier 256 interface overlay 1 otv control-group 239.1.1.1 otv data-group 239.1.1.0/29 otv join-interface ethernet 2/1 otv extend-vlan 5-10 no shutdown
Answer options
- A. Edge Device 1 interface ethernet 2/1 ip address 192.0.2.1/24 ip igmp version 3 ip pim sparse-mode Edge Device 2 interface ethernet 2/1 ip address 192.0.2.16/24 ip igmp version 3 ip pim sparse-mode
- B. Edge Device 1 interface ethernet 2/1 ip address 192.0.2.1/24 ip igmp version 3 Edge Device 2 interface ethernet 2/1 ip address 192.0.2.1/24 ip igmp version 3
- C. Edge Device 1 interface ethernet 2/1 ip address 192.0.2.1/24 ip igmp version 3 Edge Device 2 interface ethernet 2/1 ip address 192.0.2.16/24 ip igmp version 3
- D. Edge Device 1 interface ethernet 2/1 ip address 192.0.2.1/24 Edge Device 2 interface ethernet 2/1 ip address 192.0.2.16/24
Correct answer: C
Explanation
The correct answer is C, as it provides unique IP addresses for both Edge Device 1 and Edge Device 2, which is necessary for proper communication in OTV. Option A is incorrect because it includes unnecessary configurations for PIM. Option B is wrong since it assigns the same IP address to both devices, leading to address conflicts. Option D is incomplete as it lacks the IGMP configurations required for multicast operations.
