350-601 Storage Network Practice Question
An engineer is configuring iSCSI multipath I/O (MPIO) for a storage array. The initiator has two NICs connected to two different switches, and the target has two iSCSI ports on different subnets. Which condition must be met for MPIO to function correctly?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Each path must be on a separate subnet.
MPIO requires that the initiator and target have multiple paths that are not on the same subnet to avoid routing issues. Typically, each path should be on a separate subnet.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
CHAP authentication must be disabled.
Why it's wrong here
CHAP is for authentication and does not affect MPIO functionality.
- ✓
Each path must be on a separate subnet.
Why this is correct
Separate subnets ensure distinct paths for MPIO.
- ✗
Both paths must be on the same subnet.
Why it's wrong here
Same subnet can cause issues with ARP and routing for MPIO.
- ✗
Jumbo frames must be enabled on all interfaces.
Why it's wrong here
Jumbo frames are not a requirement for MPIO.
