Which statement is true about upgrading the firmware on a Cisco MDS storage switch with dual supervisors?
Answer(s): B
Non-Disruptive Upgrades OverviewAll MDS switches support non-disruptive upgrades and downgrade subject to limitations listed in the MDS release notes.On a 95xx or 97xx Series MDS with dual supervisors, during the firmware upgrade, the new code is loaded on the standby supervisor. A switchover then occurs in order to make the supervisor that runs the new code active. The code is then loaded on the previously active supervisor, and it becomes the new standby supervisor. The data plane continues to pass fibre channel traffic. The modules then non-disruptively start at the lowest numbered module and proceed to the highest.On a 91xx, 92xx, or 93xx Series MDS, which has only one supervisor, the supervisor (control plane) is reloaded. The data plane continues to pass fibre channel traffic.

A Cisco MDS 9000 Series Storage Switch has reloaded unexpectedly.Where does the engineer look for the latest core dump file?
Answer(s): D
Saving the Last Core to BootflashThis last core dump is automatically saved to bootflash in the /mnt/pss/ partition before the switchover or reboot occurs. Three minutes after the supervisor module reboots, the saved last core is restored from the flash partition (/mnt/pss) back to its original RAM location. This restoration is a background process and is not visible to the user.

An engineer must implement a Cisco UCS system at a customer site. One of the requirements is to implement SAN boot. The storage system maps the sourceWWPN to a unique LUN.Which method does Cisco recommend to configure the SAN boot?

Refer to the exhibit. Which feature set must be used to configure on switch 2 to establish a VSAN trunk between switch 1 and switch 2?
By default, trunk mode is enabled in all Fibre Channel interfaces. However, trunk mode configuration takes effect only in E-port mode. You can configure trunk mode as on (enabled), off (disabled), or auto (automatic). The default trunk mode is on. The trunk mode configuration at the two ends of an ISL, between two switches, determine the trunking state of the link and the port modes at both ends (see Table 15-1).

An engineer is performing a configuration on a Cisco Nexus 5000 Series Switch. The requirement is for the current Fibre Channel IDs in VSAN 120 to be saved across reboots. The Cisco environment also must integrate with a third-party solution that requires persistent Fibre Channel IDs for the VSAN. The WWN of theCisco switch must be 33:e8:00:05:30:00:16:df and its Fibre Channel ID 0x070128. Which command set meets these requirements?
