What does iSCSI stand for?

• Internet Small Computer Systems Interface

• Internal Small Computer Systems Interface

• Integrated Small Computer Systems Interface

• Independent Small Computer Systems Interface

Answer explanation

iSCSI stands for Internet Small Computer Systems Interface, making the correct answer choice 'Internet Small Computer Systems Interface'.

What is a major disadvantage of iSCSI?

• It is difficult to set up

• It can run into IP-related problems

• It does not support virtualization

• It is not scalable

Answer explanation

iSCSI can run into IP-related problems, such as network congestion or conflicts, which can impact its performance and reliability.

What is the main advantage of Fibre Channel?

• It is easy to configure

• It is highly scalable

• It is cost-effective

• It uses less power

Answer explanation

The main advantage of Fibre Channel is that it is highly scalable, allowing for easy expansion and growth of the network infrastructure.

What does FCoE stand for?

• Fibre Channel over Ethernet

• Fibre Channel over External

• Fibre Channel over Expansion

• Fibre Channel over Enterprise

Answer explanation

FCoE stands for Fibre Channel over Ethernet, making it the correct choice among the options provided.

What is the purpose of Logical Unit Numbers (LUNs) in iSCSI?

• To provide unique identifiers for devices

• To increase storage capacity

• To enhance data transfer speed

• To simplify network configuration

Answer explanation

To provide unique identifiers for devices

Know that FCoE allows Fibre Channel to use 10 Gigabit Ethernet (or even higher) networks. This solves the problem of enterprises having to run parallel infrastructures for both LANs and SANs.

• FCoE allows Fibre Channel to use 1 Gigabit Ethernet.

• FCoE allows Fibre Channel to use 10 Gigabit Ethernet.

• FCoE allows Fibre Channel to use 100 Megabit Ethernet.

• FCoE allows Fibre Channel to use 5 Gigabit Ethernet.

Answer explanation

FCoE allows Fibre Channel to use 10 Gigabit Ethernet, as mentioned in the question, enabling enterprises to avoid running parallel LAN and SAN infrastructures.

What is the main advantage of Network-Attached Storage (NAS) over Storage-Area Network (SAN)?

• NAS is more costly and difficult to implement.

• NAS uses Fibre Channel.

• NAS is easier to implement and uses TCP/IP.

• NAS offers block-level access.

Answer explanation

NAS is easier to implement and uses TCP/IP, making it more user-friendly compared to SAN.

On a VLAN, what does multipathing create to increase availability and add fault tolerance?

• Single path to the storage resources.

• Multiple paths to the storage resources.

• No path to the storage resources.

• A single path to the network resources.

Answer explanation

On a VLAN, multipathing creates multiple paths to the storage resources to increase availability and add fault tolerance.

For the exam, you should know the difference between NAS and SAN technologies and how to apply them.

• True

• False

Answer explanation

True because understanding the difference between NAS and SAN technologies is essential for the exam.

Logical unit numbers (LUNs) came from the SCSI world and use “targets” that hold up to how many devices?

• 4

• 6

• 8

• 128

Answer explanation

Logical unit numbers (LUNs) in the SCSI world use 'targets' that hold up to 4 devices, making 4 the correct choice.
