CompTIA Linux+ (XK0-005) — Question 174

A junior systems administrator recently installed an HBA card in one of the servers that is deployed for a production environment. Which of the following commands can the administrator use to confirm on which server the card was installed?

Answer options

• A. lspci | egrep ‘hba|fibr’
• B. lspci | zgrep ‘hba|fibr’
• C. lspci | pgrep ‘hba|fibr’
• D. lspci | ‘hba|fibr’

Correct answer: A

Explanation

The correct command, A, uses egrep, which is appropriate for filtering the output of lspci to show lines containing 'hba' or 'fibr'. Options B and C use zgrep and pgrep, respectively, which are not suitable for this context as they do not process lspci output correctly. Option D lacks the necessary command to filter the output and is thus invalid.
