N10-009 Network Operations Practice Question
A network administrator needs to create a diagram that shows the IP addressing scheme, VLAN assignments, and routing protocols used in the network. This diagram will be used for troubleshooting and future planning. Which type of documentation should the administrator create?
⚠ Common exam trap
The N10-009 exam often tests the distinction between physical and logical documentation by describing a scenario that mixes physical and logical elements, leading candidates to mistakenly choose a physical topology diagram when the question explicitly asks for IP schemes and VLANs.
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
✓
Logical topology diagram
A logical topology diagram is correct because it documents the IP addressing scheme, VLAN assignments, and routing protocols—abstract elements that define how data flows through the network, independent of physical device locations. This type of diagram is essential for troubleshooting Layer 3 issues and planning changes to the network's logical design.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Physical topology diagram
Why it's wrong here
A physical topology diagram illustrates the actual, tangible connections between network devices, showing where cables run, the specific ports used, and the geographic location of hardware components. It provides a literal map of the physical infrastructure, including device types and their physical links. While vital for understanding the physical layout, this diagram does not inherently represent the logical IP addressing scheme, subnet boundaries, or the virtual segmentation provided by VLANs, which operate at higher OSI layers.
When this WOULD be correct
A network administrator needs to document the physical locations of devices, cable runs, and hardware connections for troubleshooting physical connectivity issues or planning hardware upgrades.
- ✓
Logical topology diagram
Why this is correct
A logical topology diagram illustrates the network's functional relationships and data flow, independent of physical layout. It explicitly depicts OSI Layer 3 elements such as IP subnets, host IP addresses, and the boundaries of VLANs, showing how broadcast domains are segmented. This type of diagram is essential for understanding routing protocols and how different network segments communicate logically, making it the ideal choice for visualizing IP addressing schemes and VLAN assignments.
- ✗
Rack elevation diagram
Why it's wrong here
A rack elevation diagram provides a front or rear view of a server rack, detailing the precise physical placement of all mounted equipment, such as servers, switches, and patch panels, within their respective rack units (RUs). This visual representation is crucial for planning physical space, power distribution, and cooling requirements within the data center. However, it offers no insight into the logical network configuration, IP addressing schemes, or VLAN assignments that govern how these devices communicate.
When this WOULD be correct
When the question asks for a diagram to plan equipment placement, cooling, power distribution, or physical access in a data center, a rack elevation diagram is the correct choice.
- ✗
Cable management plan
Why it's wrong here
A cable management plan is a detailed document outlining the physical organization, routing, labeling, and pathways for network cabling within a facility or rack. Its primary purpose is to ensure neatness, accessibility, and proper airflow for physical infrastructure, facilitating maintenance and troubleshooting of physical connections. This plan focuses exclusively on the tangible cables and their physical arrangement, not the logical IP addressing or VLAN configurations applied to the network interfaces.
When this WOULD be correct
When the question asks for documentation to organize and label physical cable runs in a data center or wiring closet to ensure neatness and facilitate maintenance.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The N10-009 exam frequently reuses these exact scenarios with slightly different constraints.

✗Physical topology diagramWrong answer — click to see why▾
Why this is wrong here
A physical topology diagram shows hardware layout and cabling, not IP addressing, VLANs, or routing protocols, which are logical constructs.
★ When this WOULD be the correct answer
A network administrator needs to document the physical locations of devices, cable runs, and hardware connections for troubleshooting physical connectivity issues or planning hardware upgrades.
Why candidates choose this
Candidates may confuse 'physical' with 'logical' documentation, assuming all network diagrams are physical, or they may think IP and VLAN info is tied to physical layout.
✗Rack elevation diagramWrong answer — click to see why▾
Why this is wrong here
A rack elevation diagram shows the physical placement of equipment in racks, not IP addressing, VLANs, or routing protocols.
★ When this WOULD be the correct answer
When the question asks for a diagram to plan equipment placement, cooling, power distribution, or physical access in a data center, a rack elevation diagram is the correct choice.
Why candidates choose this
Candidates may confuse 'documentation' with physical layout, thinking a rack diagram includes network details, or they may not distinguish between physical and logical diagrams.
✗Cable management planWrong answer — click to see why▾
Why this is wrong here
A cable management plan documents physical cable routing and labeling, not IP addressing, VLANs, or routing protocols, which are logical network elements.
★ When this WOULD be the correct answer
When the question asks for documentation to organize and label physical cable runs in a data center or wiring closet to ensure neatness and facilitate maintenance.
Why candidates choose this
Candidates may confuse cable management with network documentation, thinking it includes all aspects of network planning, but it is limited to physical cabling details.

Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.

Key term
VLAN
A VLAN (Virtual Local Area Network) is a logical grouping of network devices that behave as if they are on the same physical network segment, regardless of their actual physical location.
Key term
VLAN
A VLAN logically segments a physical network into isolated broadcast domains without requiring separate physical switches.
