350-601 Storage Network Practice Question
An engineer is configuring intelligent zoning and wants to use device aliases to simplify zone membership. What is a characteristic of device aliases compared to zone aliases?
⚠ Common exam trap
Cisco often tests the distinction between device aliases (global, VSAN-independent) and zone aliases (local, VSAN-specific), and the trap here is that candidates confuse the scope of these two alias types, assuming device aliases are also VSAN-restricted.

Correct answer & explanation
✓
Device aliases can be used in multiple zones across different VSANs.
Device aliases are globally unique across all VSANs in a Cisco MDS fabric, allowing the same alias to be used in multiple zones and across different VSANs without conflict. This simplifies zone configuration because a single device alias can represent an N-port (e.g., a host HBA) and be referenced in zone memberships for different VSANs, reducing administrative overhead. In contrast, zone aliases are local to a single VSAN and cannot be shared across VSANs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Device aliases require a specific DNS entry.
Why it's wrong here
Device aliases are local to the switch or fabric.
- ✗
Device aliases are restricted to a single VSAN.
Why it's wrong here
Device aliases are VSAN-wide; zone aliases are per-zone.
- ✗
Device aliases are automatically assigned to the default zone.
Why it's wrong here
Device aliases do not affect default zone membership.
- ✓
Device aliases can be used in multiple zones across different VSANs.
Why this is correct
Device aliases are global and can be reused across VSANs.
