A Compute Engine instance failed to boot. Which two checks should you perform? (Choose two.)

A failed boot often points to issues with the instance's core components. A corrupted file system can prevent the operating system from loading essential files, leading to boot failure. Similarly, a boot disk that is completely full leaves no space for the operating system to operate or for temporary files needed during startup, also causing a boot failure. Accessing Compute Engine as a different SSH user is irrelevant to a boot failure, as SSH access requires the instance to be running. Troubleshooting firewall rules or routes is a networking concern and won't prevent an instance from booting, though it might prevent access after booting. Checking for dropped network traffic is also a post-boot networking diagnostic.
