Which of the following statements about Nokia's SR Linux logging is FALSE?

  1. SR Linux logs are handled using facility Iocal6 of the native Linux syslog utility.
  2. SR Linux logs can be saved locally as an encrypted file.
  3. SR Linux supports the use of filters to select log messages.
  4. Logging parameter configuration is translated into the /etc/rsyslog.conf file.

Answer(s): B

Explanation:

Nokia SR Linux does not natively support saving logs locally as encrypted files. Logs are managed using standard Linux syslog facilities and can be filtered, but encryption of local log files is not a built- in feature.



Which of the following is NOT a valid logging source used in Nokia's SR Linux?

  1. Linux facility + priority
  2. Console
  3. SR Linux subsystem + priority
  4. Syslog filter

Answer(s): D

Explanation:

"Syslog filter" is not a logging source; it is a mechanism used to filter log messages. Valid logging sources in SR Linux include Linux facility + priority, console, and SR Linux subsystem + priority.



Based on the exhibit output, what CLI command can be used to display the contents of "bgp-log" in Nokia's SR Linux?

  1. show system logging buffer bgp-log
  2. show system logging file bgp-log
  3. info system logging buffer bgp-log
  4. info system logging file bgp-log

Answer(s): B

Explanation:

The "bgp-log" is defined as a log file in the configuration, so the correct command to display its contents is show system logging file bgp-log.



Which of the following statements about using BFD with BGP is FALSE?

  1. It can help rapidly detect link failures.
  2. The BFD endpoints agree on the send/receive rate of control packets.
  3. BGP is notified if several BFD control packets are missed.
  4. Using BFD can speed up the BGP advertisement interval.

Answer(s): D

Explanation:

BFD helps detect link failures rapidly and notifies BGP to trigger route updates quickly, but it does not speed up the BGP advertisement interval itself. BGP advertisement intervals are controlled by BGP timers, not by BFD.
