100-150 Question 230
Select 4You are troubleshooting a network issue and need to collect data about a network device. Which of the following methods can you use to access and gather information about the device?
- A
Using a CLI-based protocol like SSH to connect directly to the device
- B
Utilizing SNMP to retrieve performance metrics and device status
- C
Accessing the device's management interface through a web browser (HTTP/HTTPS)
- D
Performing a traceroute to the device's IP address
- E
Using a syslog server to analyze logs sent by the device
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Accessing and collecting data about network devices can be done through various methods, depending on the type of information required and the tools available. SSH provides command-line access for configuration and diagnostics, SNMP enables performance monitoring, HTTP/HTTPS allows access to web-based management interfaces, and syslog servers collect logs for analysis. Traceroute, while useful for path analysis, does not provide device-specific data directly.
- A. Correct.
Using a CLI-based protocol like SSH allows direct access to the device's configuration and operational data. It is a common method for gathering device information.
- B. Correct.
SNMP (Simple Network Management Protocol) is specifically designed to monitor and collect data from network devices, such as traffic statistics and device health.
- C. Correct.
Accessing the device's management interface via HTTP/HTTPS provides a graphical or web-based interface to view and collect data about the device.
- D. Incorrect.
While traceroute can provide insights into the path packets take to reach the device, it does not give direct information about the device's configuration or performance.
- E. Correct.
A syslog server collects and analyzes logs sent by network devices, which can provide critical information about their operation and issues.
