An engineer is troubleshooting issues in Cisco UCS Director. Drag and drop the possible causes from the left onto the corresponding issues on the right. <DragDrop items={["Network connectivity is lost between the Cisco UCS Director Bare Metal Agent and the Windows server.","Power fails on the server that runs Cisco UCS Director.","The Cisco UCS Director appliance and the Cisco UCS Director Bare Metal Agent have a discrepancy in the system time.","The VM has VNC enabled."]} slots={[{"answer":"Power fails on the server that runs Cisco UCS Director.","id":"slot1","label":"The master inventory database fails."},{"answer":"The VM has VNC enabled.","id":"slot2","label":"The VMRC HTML5 console fails to launch."},{"answer":"Network connectivity is lost between the Cisco UCS Director Bare Metal Agent and the Windows server.","id":"slot3","label":"The PXE boot tasks fail after a successful deployment of a server running Windows Server."},{"answer":"The Cisco UCS Director appliance and the Cisco UCS Director Bare Metal Agent have a discrepancy in the system time.","id":"slot4","label":"A Cisco UCS Director appliance fails to display new images added to the Cisco UCS Director Bare Metal Agent."}]} explanation={"A power failure on the host running the Cisco UCS Director VM can crash or corrupt the inventory database. VMRC HTML5 cannot launch when VNC is enabled on the VM. The Windows PXE workflow requires network connectivity between the deployed Windows server and the Bare Metal Agent so the final PowerShell notification can complete. The Cisco UCS Director appliance and Bare Metal Agent must have synchronized time for newly added Bare Metal Agent images to display.\n\n**Learn more:** [Cisco UCS Director Troubleshooting Guide — Issues and Solutions](https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-director/troubleshooting-guide/cisco-ucs-director-troubleshooting/issues_and_solutions.html) · [Cisco UCS Director Troubleshooting Guide — Issues and Solutions (PDF)](https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-director/troubleshooting-guide/cisco-ucs-director-troubleshooting/issues_and_solutions.pdf)"} reuse={false} />

Question 2 · Network Open

Refer to the exhibit. Interface fc1/5 is offline. What action should be taken to troubleshoot this problem?

Question exhibit
Answer: D An NPV server interface reports an unavailable upstream port when its upstream NP ports and downstream server F ports are not in the same VSAN. Both sets of ports must be configured in VSAN 100 so the NPV device has an available upstream path. **Learn more:** [Cisco Nexus 6000 Troubleshooting Guide — NPV upstream port not available](https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus6000/sw/troubleshooting/guide/n6k_trouble/n6k_ts_sans.html)

An engineer tries to register Cisco UCS Manager with Cisco UCS Central, but the registration does not succeed. The engineer can ping Cisco UCS Central from UCS Manager. Which two actions must the engineer try to resolve the issue? **(Choose two.)**

Answer: A, D Cisco UCS Manager and Cisco UCS Central must have synchronized time and date through NTP; a time mismatch can prevent registration. Registration communication also requires HTTPS connectivity over TCP port 443, which ICMP ping does not validate. **Learn more:** [Cisco UCS Central Registration and Troubleshooting](https://www.cisco.com/c/en/us/support/docs/servers-unified-computing/ucs-central-software/212221-ucs-central-registration-and-troubleshoo.html) · [Registering Cisco UCS Domains with Cisco UCS Central](https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-manager/GUI-User-Guides/Server-Mgmt/4-0/b_Cisco_UCS_Manager_Server_Mgmt_Guide_4_0/m_gui_registering_ucs_domains_with_ucsc.html)
