Question

Exhibit

Options

• Asavecore -f vmdump.0
• Bdumpadm uncompressed
• Cgunzip vmdump.0
• Ddumpadm -z off

• A
  93% (51)
• B
  2% (1)
• C
  4% (2)
• D
  2% (1)

Explanation

savecore -f vmdump.0 is correct because the -f flag forces savecore to process the specified compressed dump file and extract the two expected output files (unix.N and vmcore.N) from it - exactly what the documentation describes for a vmdump.0 crash dump. Option B (dumpadm uncompressed) is wrong because dumpadm configures the dump subsystem and has no uncompressed subcommand. Option C (gunzip vmdump.0) is wrong because vmdump files use a proprietary Solaris dump format, not standard gzip compression, so gunzip would either fail or produce unusable output. Option D (dumpadm -z off) simply disables compression for future dumps - it does nothing to process an existing dump file. Memory tip: Associate savecore -f with "force extraction from a file" - whenever you have a raw dump file you need to crack open into its two components, -f is your flag.
