Question 1

What is the purpose of multipathing software in a SAN environment?

Accepted Answer

To provide redundant I/O paths between a host and storage, enabling load balancing and failover

Answer

Multipathing software manages multiple physical paths between a host and storage array, enabling failover if one path fails and optionally balancing I/O across paths.

Question 2

In data center storage design, what does 'geo-redundancy' refer to?

Accepted Answer

Maintaining copies of data across geographically separated facilities

Answer

Geo-redundancy distributes data across physically separate locations to protect against site-level disasters such as fires, floods, or power outages.

Question 3

Which storage protocol encapsulates Fibre Channel frames inside Ethernet frames to converge SAN and LAN traffic on a single network?

Accepted Answer

FCoE (Fibre Channel over Ethernet)

Answer

FCoE wraps native Fibre Channel frames in Ethernet, allowing organizations to carry SAN traffic over a Converged Enhanced Ethernet (CEE) network alongside LAN data.

Question 4

What is the purpose of storage-level encryption in a data center?

Accepted Answer

To protect data at rest from unauthorized access if physical media is removed or stolen

Answer

Storage-level encryption ensures that data on physical media is unreadable without the correct keys, protecting sensitive information from physical theft or unauthorized media access.

Question 5

What distinguishes scale-out storage from scale-up storage architecture?

Accepted Answer

Scale-out adds capacity by adding more nodes to a cluster; scale-up adds capacity by upgrading a single system's components

Answer

Scale-out storage grows horizontally by adding independent nodes to a distributed cluster, while scale-up grows vertically by adding drives or controllers to a single system.
