Demo Questions
Question 1
Which IBM XIV replication feature provides the ability for a remote target volume to be initialized without requiring the contents of the source volume to be re-replicated over an inter-site link?
- Offline Initialization
- Quick Initialization
- Synchronous Replication
- Asynchronous Replication
Correct answer: A
Explanation:
When an XIV mirror coupling is first activated, all actual data on the source is either copied to the destination (normal initialization) or verified to be on the destination, and only changed data is copied (offline initialization). This process is referred to as initialization.

Question 2
What is the complete source of information for power, cooling, and floor space requirements for IBM tape products?
- Preinstall TDA checklist
- Product announcement letters
- Installation and Planning Guide
- IBM Storage System Interoperation Center
Correct answer: A
Explanation:
The Technical Delivery Assessment (TDA) pre-installation checklist and worksheets document provides several worksheets that the customer must complete for each XIV system.

Question 3
Which function provides a high availability feature with dual-site, active-active access to a volume in IBM Spectrum Virtualize?
- Hypersite
- Hyperledger
- Hyper-Scale
- HyperSwap
Correct answer: D
Explanation:
You can create an IBM HyperSwap topology system configuration where each I/O group in the system is physically on a different site. When used with active-active relationships to create HyperSwap volumes, these configurations can be used to maintain access to data on the system when power failures or site-wide outages occur.
