Question 354 of 464
N10-009 Network Operations Practice Question
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?
⚠ Common exam trap
Many 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.
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.
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
Simple Network Management Protocol (SNMP) is primarily utilized for monitoring and managing network devices, allowing administrators to query device status, modify configurations, and receive asynchronous "traps" for specific events. While SNMP traps can signal critical occurrences, they are concise notifications, not detailed log messages. SNMP is not engineered for the continuous, high-volume transmission of comprehensive log data that a centralized logging system requires for deep analysis.
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 the industry-standard protocol designed specifically for the real-time transmission of event and log messages over an IP network from various network devices to a centralized logging server. This enables efficient collection, storage, and analysis of critical operational data, which is essential for network monitoring, security auditing, and troubleshooting. Its standardized message format allows for interoperability across diverse hardware vendors.
- ✗
SMTP
Why it's wrong here
Simple Mail Transfer Protocol (SMTP) is fundamentally designed for sending and receiving electronic mail messages between mail servers. While it could theoretically be configured to email log files, this method is highly inefficient and impractical for real-time, high-volume log collection from multiple network devices. SMTP lacks the structured logging capabilities and immediate processing required for effective centralized log analysis, making it unsuitable for this purpose.
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
File Transfer Protocol (FTP) is a standard network protocol used for transferring computer files between a client and server on a computer network. While log files could certainly be transferred using FTP, it operates at the file level, not as a real-time event logging mechanism. This approach would necessitate manual or scheduled transfers of entire log files, completely lacking the immediate, stream-based collection and structured message handling inherent to dedicated logging protocols.
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.

✗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.
