Setting the TF_LOG environment variable to DEBUG causes debug messages to be logged into syslog.

• A. True
• B. False
• C. Only when running Terraform with the -log=debug flag
• D. It logs to the console, not syslog

Answer: (B)

TF_LOG controls how verbose Terraform’s internal logging is, not where the logs go. When you set TF_LOG to DEBUG, Terraform outputs detailed messages to the command’s standard error (stderr). It does not send those messages to syslog by default. If you want to capture logs in a file, you can set TF_LOG_PATH to a file path, or redirect stdout/stderr as needed. The -log=DEBUG flag operates at runtime for verbosity in the console, but it doesn’t switch the sink to syslog either. So the statement is false.
