The answer is SNMP, the Simple Network Management Protocol, which is the correct choice because it is the standard protocol specifically designed for network management and monitoring. SNMP allows a network management station to query managed devices like routers for system information—such as operating system version and uptime—by reading Object Identifiers (OIDs) stored in the Management Information Base (MIB). On the CompTIA Network+ N10-009 exam, this question tests your understanding of which protocol is purpose-built for centralized network monitoring rather than for file transfer (FTP), email (SMTP), or secure shell access (SSH). A common trap is confusing SNMP with ICMP, which is used for connectivity testing (ping), not for retrieving detailed device inventory data. Remember the memory tip: SNMP stands for “Simple Network Management Protocol,” and the “M” in both SNMP and “Management” reminds you it’s the go-to for monitoring and managing network devices.
N10-009 Network Operations Practice Question
This N10-009 practice question tests your understanding of network operations. 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 technician needs to retrieve the operating system and uptime information from a router for inventory purposes. Which protocol is specifically designed for network management and monitoring?
Why wrong: SMTP is used for sending email, not for network management queries.
B
SNMP
SNMP is used to manage and monitor network devices, including retrieving system information like OS and uptime via MIB objects.
C
HTTP
Why wrong: HTTP is used for web traffic and may provide a web interface, but it is not a protocol specifically designed for automated network management inventory.
D
FTP
Why wrong: FTP is used for file transfer and could be used to retrieve configuration files, but it is not designed for querying system status information like OS version and uptime.
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 standard protocol specifically designed for network management and monitoring. It allows a network management station to query managed devices (like routers) for system information, including operating system version and uptime, via OIDs (Object Identifiers) in the MIB (Management Information Base).
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
CompTIA often tests that candidates confuse SNMP with other application-layer protocols like HTTP or FTP, assuming any protocol that can 'retrieve information' qualifies, but only SNMP is purpose-built for network management with standardized MIB structures.
Detailed technical explanation
How to think about this question
SNMP operates over UDP ports 161 (queries) and 162 (traps), and uses a manager-agent model where the agent on the router exposes data via a MIB. For retrieving OS and uptime, the technician would query OIDs such as 1.3.6.1.2.1.1.1.0 (sysDescr) for OS info and 1.3.6.1.2.1.1.3.0 (sysUpTime) for uptime, which are defined in RFC 1213. A real-world scenario is using SNMPv3 for secure inventory collection across a large enterprise network, avoiding the overhead of CLI scripting.

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.
