An engineer is recovering a fabric interconnect from a failed upgrade.
The engineer booted the fabric interconnect to the switch(boot)# prompt and copied all the required images.
Which image must be linked to nuova-sim-mgmt-nsg.0.1.0.XXXXXXXXX1 bin to make the management image compliant with the Cisco UCS Manager?

A customer configures HSRP between two data centers that are interconnected with OTV. The configuration succeeds, but traffic between two ESXi virtual hosts on the same site is routed suboptimally through the OTV overlay.
Which two actions optimize the traffic? (Choose two.)
- A . Disable first-hop redundancy.
- B . Filter HSRP traffic by using a Layer 3 VACL on the OTV edge devices.
- C . Filter HSRP by using a Layer 2 MAC-list on the ESXi vSwitch.
- D . Filter HSRP traffic by using a Layer 3 VACL on the ESXi vSwitch.
- E . Filter HSRP by using a Layer 2 MAC-list on the OTV edge devices.
After upgrading a client’s fabric interconnect to the latest version, an engineer discovers that the appliance has lost its entire configuration.
Which two locations should an engineer check to confirm that the appliance had backed up the configuration prior to the upgrade in order to retrieve the lost configuration? (Choose two.)
- A . Equipment FSM page, InternalBackup stage
- B . Service profiles page, InternalBackup stage
- C . Admin page, PollInternalBackup stage
- D . Equipment FSM page, PollInternalBackup stage
- E . Admin page, InternalBackup stage.
An engineer is implementing a new BGP peering in their new data center. The engineer set up the BGP session that peers with the remote end. As soon as the BGP peers attempt to exchange routing prefixes, one of the BGP peers drops the connection. After reviewing the configuration, the engineer reviews the logging messages. The engineer discovers that the router is missing keepalives from the remote end and terminates the session.
Which action resolves the issue?
- A . Set the bgp transport path-mtu-discovery attribute on both peers
- B . Set the higher values for the BGP keepalive and hold-down timers on both peers
- C . Configure the matching BGP AS numbers between the peers
- D . Configure the matching BGP passwords between the peers
Refer to the exhibit.
An engineer is troubleshooting the connectivity between Server-1 and Server-2.
Which action resolves the connectivity issue?
- A . Enable BGP advertise pip feature on both leaf switches
- B . Configure the same source IP address on NVE and virtual peer link on leaf switches
- C . Classify CFS messages for strict priority queue on spine switches
- D . Change all ports on spine switches as port-type fabric

One of Cisco Nexus Series interfaces has become errdisabled with the error message “DCX-No ACK in 100 PDUs”.
What is the cause of this error?
- A . The host has not responded to the Control Sub-TLV DCBX exchanges of the switch.
- B . The acknowledgement number in the server response has not incremented for 100 exchanges.
- C . Cisco Discovery Protocol is disabled on the switch.
- D . LLDP is disabled on the switch.
Refer to the exhibit.
A recent configuration change removes the HSRP adjacency between the SW-1 and SW-2 Cisco Nexus switches. The change causes the servers on this subnet to lose Internet access.
Which action restores the connectivity of all servers on VLAN 13?
- A . Disable HSRP IP redirects on SW-1.
- B . Set the HSRP priority to 70 on SW-1.
- C . Activate HSRP preempt on SW-2.
- D . Set the HSRP password on SW-2.
Refer to the exhibits.
An engineer is implementing the SAN based on the Cisco MDS 9000 Series Switches. When operating the environment, the engineer encounters the error shown.
Which action resolves the issue?
- A . Copy VSAN 101 to the fabric binding database on the MDS-1 switch
- B . Add the World Wide Name of the neighboring switch to the MDS-1 switch
- C . Configure the port security feature on the MDS-1 switch
- D . Enable VSAN 101 on the peer MDS 2 switch fabric interconnect
