You receive an alarm that your Junos device is experiencing problems regarding temperature. Which two commands would you use to investigate this problem? (Choose two.)

`show chassis hardware` displays information about the physical components installed, not their current operational status or temperature readings.

The `show chassis temperature-thresholds` command displays the configured temperature thresholds for various components, allowing verification of alarm limits against current readings.

`show chassis pic fpc-slot <value> pic-slot <value>` displays information specific to a particular PIC, which might include some environmental data, but `show chassis environment` offers a broader view of all chassis temperatures.

The `show chassis environment` command provides comprehensive real-time information about the chassis's operational environment, including current temperatures of various components, which is essential for diagnosing temperature issues.
