Refer to the exhibit. The virtual machines running on Cisco UCS B-Series blades are experiencing performance issues that affect the network connectivity of the target application. The issue is intermittent and affects only some of the connectivity sessions. Which action resolves the issue?
Answer(s): B
FCS Errors and Receive Errors usually indicate a physical layer problem, which could be caused by a faulty cable or a bad transceiver between the UCS Fabric Interconnect and the switch.Since the issue is intermittent and specific to certain ports, replacing the cable and transceiver is a logical step to resolve these physical layer issues and restore stable connectivity.
An engineer is troubleshooting a "Discovery Failed" error on a Cisco UCS C-Series server. The server is configured to be managed by the fabric interconnect directly. The engineer discovered that only the data connection is established with the fabric interconnect. Which port must be connected from the server to the fabric Interconnect to resolve the issue?
Answer(s): D
CIMC (Cisco Integrated Management Controller) is the management interface for Cisco UCS C-Series servers, allowing out-of-band management. If a "Discovery Failed" error occurs and only the data connection is established, it indicates that the management connection (required for server discovery and management) is not properly set up.To resolve this issue, you need to connect the CIMC port on the server to the fabric interconnect, ensuring that the server can be fully managed by the UCS Manager via the fabric interconnect.
A maintenance operation on power rail A caused a reboot of the servers in a Cisco UCS B-Series chassis. The Cisco UCS system has these attributes:•The system is equipped with four PSUs.•N+1 mode is used.•PSU 1 and 2 are connected to rail A.•PSU 3 and 4 are connected to rail B.Which action prevents server reboot when rail A goes down?
In the current setup, PSU 1 and 2 are connected to rail A, and PSU 3 and 4 are connected to rail B. When rail A goes down, both PSU 1 and 2 are lost, leaving only the power from rail B (PSU 3 and 4), which might not be sufficient depending on the load, causing the servers to reboot.By configuring nonredundant mode with PSU1 and PSU3 on rail A and PSU2 and PSU4 on rail B, you distribute the power more evenly across the power rails. This ensures that both power rails provide power to the system, preventing a complete power failure in the event of one rail going down.
A Cisco UCS C125 M5 server is integrated with Cisco UCS Manager using direct connect mode. The adapter for the server is reported as "inoperable" inside Cisco UCS Manager. Which action resolves the issue?
Answer(s): C
When an adapter is reported as "inoperable" in Cisco UCS Manager, one common cause is a firmware mismatch between the adapter and the version of Cisco UCS Manager. For the hardware to be recognized and function correctly, the firmware of the adapter must be compatible with the version of UCS Manager. Updating the adapter's firmware to match the UCS Manager version typically resolves this issue.While reseating the adapter or checking physical connections might also help in some cases, firmware compatibility is a common reason for this type of error, especially in direct-connect environments like with the Cisco UCS C125 M5 server.
An engineer must migrate a blade from UCS Domain A to UCS Domain B. The environment has these configurations:•B200 M5 contains a VIC 1440 that runs 4.0(4)B.•UCS Domain A is a Cisco UCS Fabric Interconnect 6248UP that runs 4.0(4)A.•UCS Domain B is a Cisco UCS Fabric Interconnect 6296UP that runs 3.1 (3)A.•Both domains use a Cisco UCS 5108 Chassis with 2208 IOM. When the engineer inserts the blade into UCS Domain B, it fails to be discovered by Cisco UCS Manager. Which action resolves the issue?
The issue arises because UCS Domain B is running a lower version of UCS Manager (3.1(3)A), while the blade's VIC 1440 and firmware version is 4.0(4)B, which is incompatible with the older UCS version in Domain B.To resolve this, you need to upgrade UCS Domain B to version 4.0(4)A, so that it is compatible with the firmware and hardware (VIC 1440) on the B200 M5 blade.
