Answer everything, then click Check: your score and explanations will appear.

3.1 · Recall

1. The 3-2-1 rule is…

2 copies on the same medium 3 copies, 2 media, 1 offsite No copy, all local 1 copy on 1 local disk

3 copies on 2 media including 1 offsite: the rule covering every scenario.

3.1 · Application

2. Karim fears ransomware. Which copy really protects him?

The continuously synced copy The recycle-bin content The external drive unplugged in between The file left open on screen

Only the offline copy escapes encryption of everything connected.

3.2 · Recall

3. On public Wi-Fi, the rule for work…

Screen shared with neighbours Mandatory corporate VPN No special precaution Firewall off to go fast

Unmanaged network = mandatory encrypted tunnel for business data.

3.2 · Application

4. Karim must send a file from a café. What to choose?

A stranger's free VPN Open Wi-Fi without VPN directly A nearby generically named network 4G/5G tethering, otherwise Wi-Fi + VPN

Traveller hierarchy: 4G/5G first, otherwise Wi-Fi + corporate VPN.

3.2 · Arbitration

5. The HTTPS padlock is present, no VPN, for a business file. Call?

Insufficient: enable the corporate VPN Useless: disconnect the active VPN Sufficient: HTTPS replaces everything Sufficient: the network name is enough

HTTPS protects one site, VPN protects all traffic: the two complement each other.

3.3 · Recall

6. A USB drive found in a car park…

Keep it for personal use Format it yourself at the office Never plug it in, hand it to IT Plug it in to identify the content

Abandoned drive = classic vector: isolated analysis by IT.

3.3 · Application

7. Karim must send a document to a partner. Best?

A cleartext personal drive A controlled corporate cloud link A copy with no scan or trace An unencrypted drive handed over by hand

The controlled link leaves a trace and is revoked; the drive gets lost.

3.3 · Arbitration

8. A drive carries sensitive data, in cleartext. Risk and fix?

Simple deletion is enough Plug in everywhere to check Loss = leak: encrypt the drive No risk, carry in cleartext

Encrypted, it is a lost object; in cleartext, it is a data leak.

3.4 · Application

9. Karim sends an encrypted archive. The password…

In cleartext in the file name In the same email as the file In the subject of the same message Via ANOTHER channel than the file

Two-channel rule: file and key separated, never together.

3.4 · Application

10. Karim's laptop could be stolen. The lasting fix?

Check active disk encryption Write the password on the screen Disable all locking Leave the disk in visible cleartext

Encrypted disk = stolen laptop unreadable without the key.

3.4 · Arbitration

11. Archive password lost, no copy in the manager. Outcome?

Encryption removes itself One email recovers everything IT guesses the lost password The file stays permanently unreadable

That is the point: passwords in the manager, BitLocker keys with IT.

3.5 · Application

12. Karim works remotely. The three router settings?

Admin changed, WPA2/3, separate guest Speed, channel and brand No setting needed Colour, name and position

Admin + WPA2/3 + guest: home aligned with the office.

What's next?

Score ≥ 80%: move to Level 4 — personal data and GDPR in daily life (spot, minimize, report).
Score < 80%: revisit the missed sections (3-2-1 in 3.1, VPN in 3.2, two channels in 3.4), reread the explanations above, then retake the test.
