Palo Alto Networks Cybersecurity Entry-Level Technician (PCCET) — Question 80

The vulnerability time period from when a new, unknown threat occurs until security vendors release a signature file or security patch is known as what?

Answer options

• A. Breach time
• B. Dwell time
• C. Exposure window
• D. Zero-day threat

Correct answer: D

Explanation

The correct answer is 'Zero-day threat' as it specifically refers to vulnerabilities that are exploited before a patch is available. 'Breach time', 'Dwell time', and 'Exposure window' do not accurately capture the concept of an unaddressed threat awaiting a security response.
