Hitachi Vantara Qualified Professional - VSP 5000 Series Installation 認定 HQT-4160 試験問題 (Q20-Q25):

質問 # 20
What is a critical step in the pre-installation checklist for ensuring the physical security of the VSP
5000 system?

A. Installing surveillance cameras in the data center
B. Configuring firewall settings
C. Securing the racks to the floor
D. Setting BIOS passwords

正解：C

解説：
The Hitachi VSP 5000 is a large enterprise storage system typically installed in data center racks.
A key pre-installation physical security and safety requirement is ensuring that racks are properly anchored or secured to the floor.
This step is critical because:
The storage system is heavy and tall, creating a tip-over risk.
Anchored racks improve stability during maintenance (when components are extended).
It protects equipment from accidental movement or vibration.
Many data center safety standards require rack anchoring before installation.

質問 # 21
Which two steps should you perform before a VSP 5000 system installation? (Choose two.)

A. Ensure you have a Windows laptop configured as Maintenance laptop prior to the installation.
B. Ensure that you have the 3 CE jumpers required to configure the system.
C. Use the Administrator manual to provide the customer with a list of suitable IP addresses for their public network.
D. Use the Maintenance manual to check any power and environmental requirements.

正解：A、D

解説：
Use the Maintenance manual to check any power and environmental requirements.
Reviewing the Maintenance manual ensures that the installation site meets all necessary power and environmental specifications for the VSP 5000 system.
Ensure you have a Windows laptop configured as Maintenance laptop prior to the installation.
A properly configured Maintenance laptop is essential for system setup, configuration, and troubleshooting during the installation process.

質問 # 22
A customer wants to upgrade a diskless VSP 5100 to a VSP 5500. Which three types of components will be added during the upgrade? (Choose three.)

A. Interconnect Switches (ISWs)
B. Channel Boards (CHBs)
C. Hitachi Service and Network Box (HSNBX)
D. Controllers (CTLs)
E. Hitachi Interconnect Edges (HIEs)

正解：A、B、D

解説：
Controllers (CTLs)
Upgrading from a two-controller (2N) VSP 5100 to a four-controller (4N) VSP 5500 requires adding two additional controller blades, doubling the total from two to four to deliver the higher I/O and cache capacity of the 5500.
Interconnect Switches (ISWs)
The VSP 5500 introduces external PCIe "node interconnect switches" - 1 U switch chassis that provide the high-speed fabric and management links between controller pairs. These ISW modules must be added to interconnect the expanded controller set in a 4-node configuration.
Channel Boards (CHBs)
Each new controller requires its own set of front-end channel boards for host connectivity. When you add two controllers, you also add their associated CHBs (FC, iSCSI, FICON, etc.) to furnish the additional host ports on the VSP 5500.

質問 # 23
During the parts-replacement process on a VSP 5000 storage system, what is the recommended action before removing any component?

A. Notifying all connected users about the impending downtime
B. Ensuring the system is in maintenance mode
C. Documenting the serial number of the component
D. Isolating the power supply to the specific component

正解：B

解説：
Before replacing any component in a Hitachi VSP 5000 storage system, it is critical to put the system or the affected controller/module into maintenance mode.
This ensures:
No active I/O is directed to the component being replaced.
Data integrity is preserved during the removal and replacement process.
The system prevents accidental disruptions to other parts of the storage array.
Automatic failover or rebuild processes do not interfere with the replacement.

質問 # 24
In a VSP 5100 a drive in a RAID5 Parity Group has failed and has been blocked by the microcode. As a result, which process gets automatically started?

A. Sparing Copy
B. Correction Copy
C. Dynamic Sparing
D. Copy Back

正解：B

解説：
When a drive in a RAID5 Parity Group fails and is blocked by the microcode in a VSP 5100, the Correction Copy process is automatically started to rebuild the data onto a spare drive.
