- A
SNMP
SNMP (especially with SNMPv2c or v3) allows a management station to query device MIBs for detailed information such as interface descriptions, software versions, and status. It can also be used for discovery by polling known community strings.
- B
LLDP
Why wrong: LLDP is used to advertise and discover directly connected neighbors (device ID, port ID, capabilities). It does not provide detailed configuration or status information about non-neighbor devices.
- C
NetFlow
Why wrong: NetFlow is used for traffic flow analysis (IP traffic statistics). It does not provide device configuration or inventory data.
- D
Syslog
Why wrong: Syslog is used for collecting log messages from devices. While it may contain some informational messages, it is not designed for structured inventory or configuration polling.
Quick Answer
The answer is SNMP, or Simple Network Management Protocol, because it is the standard protocol built for network management and monitoring. SNMP enables a management system to perform automatic device discovery by querying a device’s Management Information Base (MIB) and walking through Object Identifiers (OIDs) to retrieve detailed configuration and status data, such as interface descriptions and software versions. On the CompTIA Network+ N10-009 exam, this question tests your understanding of SNMP’s role in centralized monitoring versus protocols like ICMP or SSH, which lack structured MIB-based discovery. A common trap is confusing SNMP with SNMP traps—remember that traps are for alerts, not discovery. For a memory tip, think “SNMP: Simple MIB Pull” to recall that it pulls detailed info from a device’s MIB for automatic discovery and status retrieval.
N10-009 Network Operations Practice Question
This N10-009 practice question tests your understanding of network operations. 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 is configuring a monitoring system to collect metrics from network devices. The administrator needs to ensure that the monitoring system can automatically discover the devices and obtain detailed information about their configuration and status, such as interface descriptions and software versions. Which protocol is best suited for this purpose?

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
SNMP
SNMP (Simple Network Management Protocol) is the correct choice because it is specifically designed for network management and monitoring. It allows a management system to automatically discover devices (via SNMP walks or queries to MIBs) and retrieve detailed configuration and status information, such as interface descriptions and software versions, by reading OIDs from the device's MIB. This matches the requirement for automatic discovery and detailed data collection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse LLDP's neighbor discovery capability with SNMP's management and monitoring functionality, mistakenly thinking LLDP can provide detailed device configuration and status information when it only advertises basic identity and capabilities.
Detailed technical explanation
How to think about this question
SNMP operates using a manager-agent model where the monitoring system (manager) sends GET requests to agents on devices to read OIDs defined in MIBs (e.g., RFC 1213 for MIB-II). For automatic discovery, an SNMP walk (GETNEXT requests) can traverse the entire MIB tree to enumerate all managed objects, including interface descriptions (ifDescr) and software versions (sysDescr). In real-world scenarios, SNMPv3 provides encryption and authentication, making it suitable for secure monitoring in enterprise environments.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the N10-009 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
