Refer to the exhibit. An engineer is troubleshooting a physical configuration issue in Cisco NFVI. Which two observations should be made? (Choose two.)

The correct answer is B. One RAID 1 disk failed ?correct. C. The node is still functional ?correct; RAID1 can tolerate a single disk failure. From the RAID controller output: The RAID1 virtual drive is shown as "Dgrd" (degraded) with a note: "RAID 1 in degraded state." In the PD LIST, one disk (slot 2) is marked "UGood ?active disk in slot 2 disconnected from drive group 0", while the other (slot 3) is "Onln 0"…

Explanation

From the RAID controller output: The RAID1 virtual drive is shown as "Dgrd" (degraded) with a note: "RAID 1 in degraded state." In the PD LIST, one disk (slot 2) is marked "UGood ?active disk in slot 2 disconnected from drive group 0", while the other (slot 3) is "Onln 0" (online and part of drive group 0). In a RAID 1 mirror, only one disk may fail while the array remains available. Here, one disk has failed/disconnected, the other is still online the array is degraded but operational.
