220-1102 Practice Question: A security administrator needs to securely erase…
This 220-1102 practice question tests your understanding of a security administrator needs to securely erase…. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security administrator needs to securely erase data from an SSD before repurposing it in another department. The company policy requires that data be completely unrecoverable. Which method should the administrator use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Perform a standard format using Windows File Explorer
A standard format only marks the file system as empty; data remains and can be recovered with forensic tools. It is not secure for SSDs.
B
Distractor review
Run the Diskpart clean command from a command prompt
Diskpart clean removes partition information but does not overwrite data. It is not sufficient for secure erasure.
C
Best answer
Use the ATA Secure Erase command via the drive's firmware or a trusted tool
ATA Secure Erase is specifically designed for SSDs. It triggers the drive's internal mechanism to erase all user data, including cells in spare areas, making recovery infeasible.
D
Distractor review
Degauss the drive with a strong magnetic field
Degaussing can destroy the electronics of an SSD, making it unusable. It is not a recommended method for SSDs and may not completely erase all data due to the way SSDs store information.

Common exam trap
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Technical deep dive
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

A change advisory board (CAB) approved a standard change to update antivirus definitions on all servers. The technician completes the update on a file server and verifies the server is functioning normally. According to change management best practices, what documentation should the technician complete?
Question 2
A company's change management policy requires all server changes to be approved by the Change Advisory Board (CAB). A technician discovers that a critical database server's operating system needs a security patch to comply with a new regulatory requirement that takes effect in one week. The patch has a known risk of causing service downtime. The next scheduled CAB meeting is in two weeks. What should the technician do FIRST?

FAQ
Questions learners often ask
What does this 220-1102 question test?
OSPF neighbours must agree on key parameters.
What is the correct answer to this question?
The correct answer is: Use the ATA Secure Erase command via the drive's firmware or a trusted tool — For SSDs, the ATA Secure Erase command is the recommended method because it issues a built-in command to the drive controller to clear all data cells. Degaussing can damage SSDs, and standard formatting or Diskpart clean commands do not guarantee complete data removal due to wear leveling and spare area.
What should I do if I get this 220-1102 question wrong?
Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related 220-1102 OSPF questions on adjacency and route selection.
