ITPEC FE Morning April 2020 Question 13
Topic: System Component
As a backup system configuration, which of the following is an appropriate description of a hot site?
Explanation
A standby site kept up to date over the network, taking over at once — that is a hot site.
Backup sites are ranked by how much is ready before a failure:
- •Hot site: a standby system is running, with data and programs updated continuously over the network, so business resumes immediately
- •Warm site: hardware is installed in advance and backups are delivered periodically; the system is restored from them after the failure
- •Cold site: only space and utilities are reserved; hardware, data and programs are brought in and set up after the failure
Answer (b)
Why not others:
- •(a) — a shared facility where the system is rebuilt from backups only after the failure; nothing runs in advance, so it is a cold-type arrangement
- •(c) — hardware, data and programs all arrive at the reserved site after the failure: a cold site
- •(d) — hardware installed and periodic backups stored in advance, then restored after the failure: a warm site
Key rule: The less that is already running at the backup site, the colder it is; only a hot site keeps its data current, so only it can resume immediately.
