- A
The storage array must be configured with multiple target portals (IP addresses).
Multiple target portals allow connection to different paths.
- B
The target must present a single IP address for all paths.
Why wrong: The target must have multiple IP addresses to support multiple paths.
- C
The initiator must have multiple network interfaces connected to different subnets.
Multiple interfaces provide path diversity for MPIO.
- D
The initiator and target must use CHAP authentication.
Why wrong: CHAP is optional for iSCSI, not required for MPIO.
- E
Jumbo frames must be enabled on all switches.
Why wrong: Jumbo frames are optional, not required for MPIO.

350-601 Storage Network Practice Question
This 350-601 practice question tests your understanding of storage network. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network administrator is configuring iSCSI multipath I/O (MPIO) for a storage array. Which two conditions are required for MPIO to operate correctly? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The storage array must be configured with multiple target portals (IP addresses).
MPIO requires multiple network paths between the initiator and target. The target must present multiple IP addresses (one per path) and the initiator must have multiple network interfaces.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The storage array must be configured with multiple target portals (IP addresses).
Why this is correct
Multiple target portals allow connection to different paths.
Related concept
CIDR notation defines the prefix length.
- ✗
The target must present a single IP address for all paths.
Why it's wrong here
The target must have multiple IP addresses to support multiple paths.
- ✓
The initiator must have multiple network interfaces connected to different subnets.
Why this is correct
Multiple interfaces provide path diversity for MPIO.

Why it's wrong here
Jumbo frames are optional, not required for MPIO.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 350-601 subnetting questions on CIDR, address ranges, and subnet selection.
