CV0-003 Question #110: Real Exam Question with Answer & Explanation
The correct answer is C: Multipathing. Multipathing creates multiple physical I/O paths between servers and storage devices, distributes access across drives, and allows administrators to dynamically add or remove path mappings between physical storage and virtual servers.

Question
A system administrator needs to spread data storage allocation across multiple physical drives and ensure that these are mapped properly to communicate with the virtual server farm. The administrator also needs the ability to quickly create or remove these mappings so data storage is not assigned without being used. Which of the following storage techniques would fit these requirements?
Options
- AVirtual LUN
- BSubnet masking
- CMultipathing
- DPhysical LUN
Explanation
Multipathing creates multiple physical I/O paths between servers and storage devices, distributes access across drives, and allows administrators to dynamically add or remove path mappings between physical storage and virtual servers.
Common mistakes.
- A. A Virtual LUN abstracts logical storage volumes from physical media but does not inherently provide multi-path I/O routing across multiple physical drives or the dynamic path-level mapping management described in the scenario.
- B. Subnet masking is a network IP addressing technique that defines logical network boundaries and has no relationship to storage path mapping or physical drive allocation.
- D. A Physical LUN directly maps to a specific physical storage location and lacks the flexibility to quickly create or remove mappings dynamically across multiple drives.
Concept tested. Multipathing for dynamic storage path management
