• Question 93:

  A SAN is configured with multiple physical paths to each device for each client system.

  For a specific client, only a subset of visible devices requires management by Device Mapper Multipath. The device in question is visible as /dev/sdf and /dev/sdh to that client.

  Examine the code fragment from /etc/multipath.conf that is proposed configuration to solve the problem:

  

  Which statement is true?

  A. The proposed configuration does work but should not be used due to problems with device name persistence across reboots.
  B. The proposed configuration does not achieve the desired result because you cannot override blacklist entries using different identifier types.
  C. The proposed configuration does not achieve the desired result because the second path (/dev/sdh) is not referenced in blacklist_exceptions.
  D. The proposed configuration achieves the desired result. /dev/sdf and implicity its second path (/dev/sdh) are grouped into a multipath device.
