✍️ Sample CSCU Questions & Answers

1. What is the key difference between incremental and differential backups?

✓ Incremental backups only save changes since the last backup of any type, while differential backups save all changes since the last full backup

Incremental backups capture only changes since the last backup (full or incremental), using less storage but requiring more steps to restore. Differential backups capture all changes since the last full backup, using more storage but enabling faster restoration.

2. Which of the following is a method to secure your wireless network?

✓ Using WPA3 encryption

WPA3 encryption is the latest and most secure method for protecting wireless networks.

3. What should you do immediately if you suspect your password has been compromised?

✓ Change the password on that account and any account sharing that password

You should change the compromised password and every account using the same one before attackers can exploit the access.

4. What is a zero-day vulnerability?

✓ A previously unknown software vulnerability that is exploited by attackers before the vendor has developed a patch

A zero-day vulnerability is an unknown software flaw that attackers discover and exploit before the software vendor is aware of it or has released a fix, leaving zero days for users to protect themselves.

5. How can data broker websites contribute to identity theft risks?

✓ They aggregate and sell personal information that criminals can use to build profiles for identity theft

Data brokers collect and sell personal information such as addresses, phone numbers, relatives, and financial details, which identity thieves can use to answer security questions or impersonate victims.

6. What is a secure method for disposing of sensitive documents?

✓ Shredding them

Shredding sensitive documents ensures that they cannot be reconstructed and read by unauthorized individuals.
