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 administrator needs to centrally collect and analyze log messages from multiple routers and switches. Which protocol should be used to forward these log messages to a central server?
Why wrong: SNMP is used for monitoring and managing network devices, but it is not designed to forward syslog messages. SNMP typically uses traps or polls for status information.
B
Syslog
Syslog is the standard protocol for forwarding log messages from network devices to a central logging server.
C
SMTP
Why wrong: SMTP is used for email transmission, not for network device logging.
D
HTTP
Why wrong: HTTP is used for web traffic, not for log forwarding.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Syslog
Syslog (B) is the correct protocol because it is specifically designed for centralized logging and event message collection from network devices. It uses UDP port 514 (or TCP 6514 for reliable delivery) to forward log messages from routers and switches to a central syslog server, enabling administrators to collect, analyze, and archive logs from multiple devices in a standardized format.
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 SNMP traps with syslog messages, thinking SNMP can replace syslog for log collection, but SNMP traps are structured notifications for specific events, not a general-purpose log forwarding protocol.
Detailed technical explanation
How to think about this question
Syslog messages follow RFC 5424 or the older RFC 3164 format, containing a priority value (facility * 8 + severity) that allows the server to filter and categorize logs. In real-world deployments, administrators often configure logging buffered, logging host, and logging trap commands on Cisco IOS devices to control which severity levels (0-7) are forwarded, and may use TCP with logging origin-id to ensure reliable delivery and device identification.
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.
