IBM System Storage DS8000 Technical Solutions V3 Sample Questions:

1. The DS Command Line Interface (CLI) of the DS8800 can be used to perform which two of the following configuration actions?
1.Assign RAID ranks to extent pools
2.Install and activate the D68000 storage tier advisor tool
3.Invoke a server failover/fallback
4.Create and assign LUNs to hosts/servers

A) 1 and 2
B) 3 and 4
C) 2 and 4
D) I and 4

2. A customer has recently decommissioned their DS8700 wants to use the same data center floor space for a new D38 870.
What is an important fact for the technical specialist to discuss with the customer as it relates to data center requirements?

A) The rack dimensions on the DS8870 are larger than the D38700 so more floor space will be needed.
B) Air circulation in the DS8870 has changed and flows back to front so cooling vent locations will need to be adjusted.
C) The DS8870 uses a different power connector than the D68700 so new cords will need to be supplied.
D) The DS8870 uses more power than the DS8700 so more power cords will need to be ordered.

3. A customer has a mission-critical application with redundant fabrics. The customer plans to replace older EMC system with a DS8870 and a SAN Volume Controller (SVC).
Which statement best describes the impact of data migration on the production environment?

A) The production environment does not require an outage.
B) The production environment requires an outage to install the D58870.
C) The production environment requires an outage to install the SVC.
D) The production environment requires an outage to remove the EMC systems.

4. A potential DS8870 customer knows that RAID 5 works much faster and is more capacity-efficient than RAID 6, but they fear for double disk failures due to high rebuild times at large disk sizes.
How should the technical specialist address this concern?

A) Explain RAID 6 is the only applicable solution.
B) Suggest configuring large storage pools with multiple RAID 5 arrays.
C) Discuss the DSS000 Smart Rebuild function with the customer.
D) Discuss how additional hot spares can be configured per device adapter pair.

5. A customer's IT department has had problems meeting their backup window. They now mandate that a fast backup process be in place before an application is deployed. They have a DS8000 as their disk subsystem and a TS3500 tape library for backups.
What is the simplest and most effective option to satis1i this requirement?

A) ImplementFlashCopy
B) Implement TS1 140 drives
C) Increase cache size
D) Install Solid state Drives
