   A Linux host running RHEL 8 is connected to an E-Series array via two Fibre Channel HBAs. The administrator notices that only one path is active and the other shows as 'failed' in the system logs. The administrator wants to use the native Linux multipathing tool to manage the paths. What is the first step the administrator should take to resolve this?

   • AEdit '/etc/multipath.conf' to add the E-Series device as a 'blacklist' entry.
   • BReboot the host to re-initialize the HBA drivers and re-discover the paths.
   • CRun 'multipath -ll' to check the current multipath topology and identify which paths are failing.
   • DRestart the 'multipathd' service to force a re-scan of all paths.

   After configuring multipathing on a Linux host, the administrator runs 'multipath -ll' and sees the following output for a single LUN: 'dm-0 E-Series, LUN1' with two paths listed as 'active ready' and two paths listed as 'standby'. What does this indicate about the multipath configuration?

   • AThe configuration is incorrect because the E-Series array should show all paths as 'active'.
   • BThe 'standby' paths are failed and need to be replaced.
   • CThe configuration is correct, and the 'standby' paths will become 'active' if the 'active' paths fail.
   • DThe configuration is incorrect because all paths should be 'active' for proper load balancing.
