100-150 Question 231
Select 3You are troubleshooting a network issue and need to collect and access data from a switch. Which of the following methods can be used to retrieve configuration and performance data from the device?
- A
Use Secure Shell (SSH) to access the device's command-line interface (CLI)
- B
Use Simple Network Management Protocol (SNMP) to query the device for performance metrics
- C
Use a syslog server to retrieve real-time logs from the device
- D
Use Telnet to securely monitor and manage the device
- E
Use Network Time Protocol (NTP) to synchronize device logs with a time server
Show answer and explanation
Correct answers: A, B, C
Explanation
Accessing and collecting data about network devices can be achieved through SSH for secure CLI interactions, SNMP for performance and monitoring data, and syslog servers for real-time logs. These methods provide different layers of visibility into device status and operations. Telnet is not secure, and NTP is for time synchronization, not data collection.
- A. Correct.
SSH provides secure remote access to the device's CLI, allowing you to retrieve configuration and operational data directly.
- B. Correct.
SNMP is a protocol designed to collect and manage performance and monitoring data from network devices.
- C. Correct.
Syslog servers collect and store log messages from network devices, providing valuable insights into events and issues.
- D. Incorrect.
Telnet is an outdated and insecure protocol for accessing devices. It does not encrypt data, making it unsuitable for secure management.
- E. Incorrect.
NTP is used to synchronize clocks across devices but does not directly provide access to configuration or performance data.
