An engineer must configure OSPF routing on Cisco Nexus 9000 Series Switches. The IP subnet of the
Eth 1/2 interface for both switches must be advertised via OSPF. However, these interfaces must
not establish OSPF adjacency or send routing updates. The current OSPF adjacency over the
interface Eth1/1 on SW1 and Eth1/1 on SW2 must remain unaffected. Which configuration must be
applied to both Nexus switches to meet these requirements?
A.
interface ethernet 1/2
passive-interface default
B.
Interface ethernet 1/2 Ip ospf network point-to-point
C.
interface ethernet 1/2 ip ospf passive-interface
D.
interface ethernet 1/2 no ip ospf passive-Interface
Correct Answer: C
Explanation:
The ip ospf passive-interface command is used to prevent OSPF adjacency and routing updates from
being sent or received on a specific interface, while still advertising the interface subnet via OSPF. This command is useful for stub networks or loopback interfaces that do not need to form OSPF
neighbor relationships. The other commands either enable OSPF adjacency by default, change
the OSPF network type, or disable OSPF passive mode. Reference:

Question #2 (Topic: demo questions)
Which configuration statically assigns VSAN membership to a virtual Fibre Channel interface?
A.
switch(config-vsan-cb>#
B.
vsan 100 bind interface fc 3/1
C.
switch# vsan 100 fc 3/1
D.
switch(config-vsan-db)# vsan 100 interface vfc 31
Correct Answer: B
Explanation:
The vsan bind interface command is used to statically assign VSAN membership to a virtual Fibre
Channel interface. This command overrides the VSAN membership that is derived from the physical
interface or the default VSAN. The other commands are either invalid or do not apply to virtual
Fibre Channel interfaces. Reference:

Question #3 (Topic: demo questions)
An engineer updated firmware on Fabric Interconnects and activates it. However, the endpoint
fails to boot from the new firmware image. What is expected to occur in this case?
A.
The system defaults to the backup image version
B.
The system defaults to and boots into the GOLD firmware image
C.
The system defaults to the GOLD firmware image
D.
The system defaults to and boots into the kickstart image
Correct Answer: A
Explanation:
The system will automatically revert to the backup image version if the endpoint fails to boot from
the new firmware image. This is a feature of the Fabric Interconnects that ensures high availability
and reliability. The GOLD firmware image is used for diagnostics and troubleshooting, not for normal
operation. The kickstart image is used for booting the Nexus switches, not the Fabric Interconnects.
Question #4 (Topic: demo questions)
An engineer is implementing OTV on a transport that supports multicast. The solution needs to
meet the following requirements:
• Establish adjacency to the remote peer by using multicast.
• Enable OTV advertisements for VLAN 100 to the other site.
Which two commands should be configured to meet these requirements? (Choose two.)
A.
otv site-vlan 100
B.
otv data-group 232.2.2.0/28
C.
otv use-adjacency-server 172.27.255.94
D.
otv extend-vlan 100
E.
otv control-group 232.1.1.1
Correct Answer: B, D
Explanation:
To establish adjacency to the remote peer by using multicast, the engineer needs to configure the otv
data-group command with a multicast address range that is unique for each site. This command
specifies the multicast group that is used to send and receive OTV data traffic.
