ITPEC IP April 2018 Question 59
ITPEC IP April 2018 — Question 59 of 100
A UPS supplies immediate temporary power during the minute required for the private generator to start and stabilize. Its batteries prevent interruption to the server and can bridge short outages or provide enough time for a controlled shutdown.
Answer (c)
Why not others:
- an A/D converter changes an analog signal into digital data
- RAID improves storage performance or resilience against disk failures
- a firewall controls network traffic according to security rules
Key rule: A UPS handles immediate short-term power continuity; a generator supplies longer-duration backup after startup.
