An engineer fails to implement VRRP on a Cisco Nexus 7000 Series Switch. Which action resolves the issue?

  1. Activate the VRRP license.
  2. Configure the VRRP instance globally.
  3. Enable the VRRP feature.
  4. Set the VRRP group number.

Answer(s): B



Refer to the exhibit.



Two Cisco Nexus 9000 Series Switches fail to establish OSPF neighborship. Which action set resolves the issue?


  1. Configure ospf area 1 as a standard area on N9K2.
    Configure eth1/2 with IP address 10.10.128.130/25.
    Assign eth1/1 to ospf area 0.0.0.1.

  2. Configure ospf area 1 as a standard area on N9K2.
    Configure elh1/1 with IP address 10.10 128.130/25.
    Assign eth1/1 to ospf area 0.0.0.1.

  3. Configure ospf area 0 as a stub area on N9K1.
    Configure eth1/2 with IP address 10.10.1.200/25.
    Assign eth1/2 to ospf area 0.0.0.0.

  4. Configure ospf area 0 as a stub area on N9K1.
    Configure eth1/1 with IP address 10.10.128.130/25.
    Assign eth1/2 to ospf area 0.0.0.0

Answer(s): A



Refer to the exhibit.





An engineer analyzes the packet flow in a Cisco UCS domain that consists of Cisco UCS Fabric Interconnects. The engineer discovers that the virtual machine traffic goes through Cisco Fabric Interconnect B, but the traffic is expected to go through Cisco Fabric Interconnect A. Which action resolves the issue?

  1. Plug the uplink cable into a different port
  2. Allow VLAN 10 on FI-A
  3. Plug the server cable into a different port
  4. Allow VLAN 10 on FI-B

Answer(s): B

Explanation:

The issue is that traffic is expected to go through Cisco Fabric Interconnect A (FI-A), but it is going through FI-B instead. When you check the MAC address table on both fabric interconnects, you see that VLAN 10 is present on FI-B but not on FI-A. This indicates that VLAN 10 is not allowed or not configured on FI-A, which is why the traffic is being forwarded through FI-B.
To resolve this issue, you need to allow VLAN 10 on FI-A, so that traffic can flow through the correct path (FI-A) as expected.



Refer to the exhibit.





A network engineer configured Cisco Nexus 9000 Series Switches to allow the traffic between 172.16.10.10/24 to 172.18.3.100/24 to pass through the 100G-link, but it fails. SW3 and SW4 are configured with the default OSPF configurations. Which configuration on SW1 resolves the issue?


  1. interface eth1/2
    ip ospf cost 5

  2. interface eth1/2
    auto-cost reference-bandwidth 1000

  3. interface eth1/1
    ip ospf cost 1

  4. interface eth1/1
    auto-cost reference-bandwidth 10000

Answer(s): C

Explanation:

The issue here is related to OSPF cost. OSPF chooses the path with the lowest cost, and the cost is determined by the bandwidth of the link. By default, OSPF will prefer lower-cost paths for routing decisions.
In the provided scenario, you want the traffic to pass through the 100G-link (between SW3 and SW4). To achieve this, you must adjust the OSPF cost on the lower-bandwidth links (such as the 10G-links) so that OSPF prefers the 100G-link.
Setting the OSPF cost to 1 on interface eth1/1 (which connects to SW3 on a 100G-link) will make the 100G-link more favorable in OSPF path selection, as it will have a lower cost compared to the other links, ensuring that traffic flows through this link.
