1. Question 1
What is meant by the expression “The server is down”?
❌ The server is running normally
✅ The server is not running or unreachable
❌ The server has malware
Explanation:
“Down” means the server cannot respond or be accessed.
2. Question 2
Which of the following are means of storing information? (Select all that apply)

Databases and SSDs store data; application servers run applications, not store data.
3. Question 3
Which of the following are desirable backup characteristics? (Select all that apply)
✅ Availability
✅ Durability
❌ Transparency
Explanation:
Backups must be accessible and resilient. Transparency isn’t a required property.
4. Question 4
Mitigating steps to protect data from shutdowns or failures? (Select all that apply)
✅ Replication
✅ Daily Backups
❌ Password protection
Explanation:
Replication & backups reduce data loss; password protection does not mitigate shutdown failures.
5. Question 5
Location is a key distinction between cloud and traditional computing.
✅ True
❌ False
6. Question 6
