- A
SNMP
Why wrong: SNMP is used for monitoring and managing devices by reading variables and sending traps, but it is not designed for bulk log collection. Log messages are better handled by syslog.
- B
Syslog
Syslog is a protocol specifically for transporting log messages over IP networks. It allows devices to send logs to a centralized server for storage and analysis.
- C
SMTP
Why wrong: SMTP is used for email transmission. While logs could be emailed, it is not efficient for bulk, real-time log collection and analysis.
- D
FTP
Why wrong: FTP is used for file transfers. It could be used to transfer log files, but it is not a real-time logging protocol and requires manual or scheduled transfers.

A network administrator wants to collect and analyze logs from multiple network devices in a central location. Which of the following protocols should be used?
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
✓
Syslog
Syslog is the correct protocol because it is specifically designed for centralized log collection and analysis from network devices. It uses UDP port 514 (or TCP 6514 for reliable delivery) to send event messages from routers, switches, and firewalls to a central syslog server, enabling administrators to aggregate and review logs for troubleshooting and security monitoring.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SNMP
Why it's wrong here
SNMP is used for monitoring and managing devices by reading variables and sending traps, but it is not designed for bulk log collection. Log messages are better handled by syslog.
When this WOULD be correct
A network administrator needs to monitor bandwidth utilization, CPU load, and error counters on routers and switches from a central management station. SNMP would be the correct protocol to retrieve these performance metrics.
- ✓
Syslog
Why this is correct
Syslog is a protocol specifically for transporting log messages over IP networks. It allows devices to send logs to a centralized server for storage and analysis.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
SMTP
Why it's wrong here
SMTP is used for email transmission. While logs could be emailed, it is not efficient for bulk, real-time log collection and analysis.
When this WOULD be correct
When the question asks for a protocol to send log alerts or notifications via email from a monitoring system to an administrator.
- ✗
FTP
Why it's wrong here
FTP is used for file transfers. It could be used to transfer log files, but it is not a real-time logging protocol and requires manual or scheduled transfers.
When this WOULD be correct
A network administrator needs to transfer large log files from a network device to a central server for offline analysis, where the device can periodically upload logs via FTP. The question would specify batch transfer of log files rather than real-time streaming.
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.
✓SyslogCorrect answer▾
Why this is correct
Syslog is a protocol specifically for transporting log messages over IP networks. It allows devices to send logs to a centralized server for storage and analysis.
✗SNMPWrong answer — click to see why▾
Why this is wrong here
SNMP is used for monitoring and managing network devices by collecting performance metrics and status information, not for centralized log collection and analysis. Syslog is the standard protocol for log transport.
★ When this WOULD be the correct answer
A network administrator needs to monitor bandwidth utilization, CPU load, and error counters on routers and switches from a central management station. SNMP would be the correct protocol to retrieve these performance metrics.
Why candidates choose this
Candidates may confuse SNMP's monitoring capabilities with log collection, as both involve gathering data from network devices, but SNMP focuses on real-time metrics rather than event logs.
✗SMTPWrong answer — click to see why▾
Why this is wrong here
SMTP is used for sending email messages, not for collecting and analyzing logs from network devices to a central location.
★ When this WOULD be the correct answer
When the question asks for a protocol to send log alerts or notifications via email from a monitoring system to an administrator.
Why candidates choose this
Candidates may confuse SMTP with a protocol used for log transmission because both involve sending data, but SMTP is for email, not centralized logging.
✗FTPWrong answer — click to see why▾
Why this is wrong here
FTP is a file transfer protocol, not designed for real-time log collection and analysis from multiple network devices. It lacks the standardized log format and push mechanism that syslog provides for centralized logging.
★ When this WOULD be the correct answer
A network administrator needs to transfer large log files from a network device to a central server for offline analysis, where the device can periodically upload logs via FTP. The question would specify batch transfer of log files rather than real-time streaming.
Why candidates choose this
Candidates may think FTP can be used to transfer log files to a central location, overlooking that syslog is the standard protocol for real-time log collection and that FTP is not designed for continuous, automated log forwarding from multiple devices.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse SNMP traps (which are unsolicited alerts about device conditions) with syslog messages, but SNMP traps are for specific events like link up/down, not for general log collection, while syslog is the standard for aggregating all log entries.
Detailed technical explanation
How to think about this question
Syslog operates with a severity level (0-7) and facility codes to categorize messages, allowing administrators to filter critical events from informational ones. In real-world deployments, syslog can be configured with RFC 5424 format for structured data, and devices often use UDP for speed but may lose packets under load, prompting the use of TCP or TLS for reliability in high-security 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.
