350-601 Practice Question: A network administrator needs to configure iSCSI…
This 350-601 practice question tests your understanding of 350-601 exam topics. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 needs to configure iSCSI multipath I/O (MPIO) for a host connecting to a storage array. Which requirement must be met to ensure that MPIO functions correctly with load balancing?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The host must have multiple network interfaces on different subnets
MPIO requires multiple paths between the initiator and target. Each path must be on a separate network interface and subnet to provide redundancy and load balancing.
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 iSCSI initiator must use CHAP authentication
Why it's wrong here
CHAP is for authentication, not for multipathing.
✗
Jumbo frames must be enabled on all switches
Why it's wrong here
Jumbo frames are optional and not required for MPIO.
✓
The host must have multiple network interfaces on different subnets
Why this is correct
Multiple distinct network paths are required for MPIO to provide redundancy and load balancing.
The storage array must support synchronous replication
Why it's wrong here
Synchronous replication is unrelated to 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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
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.
The correct answer is: The host must have multiple network interfaces on different subnets — MPIO requires multiple paths between the initiator and target. Each path must be on a separate network interface and subnet to provide redundancy and load balancing.
