2.6 Given a scenario, implement procedures for basic small office/home office (SOHO) malware removal.
Objective 2.6 sits in Security, which carries 28% of the A+ Core 2 exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A technician finishes remediating an infected workstation and needs to limit which employees can open a shared folder that once stored the malicious files. Which feature should the technician configure to set per-user read, write, and modify permissions on that folder?
The concept
NTFS provides granular access control through ACLs attached to a file or folder's security descriptor, letting a technician specify exactly who can read, write, or modify data as part of remediation.
Why this answer
Assigning ACLs on the folder is the correct way to restrict which users can access it, which is exactly what NTFS security descriptors are designed to do.
- Correct: ACLs are the NTFS mechanism for assigning per-user or per-group permissions.
- BSelf-healing NTFS repairs minor file system corruption automatically; it does not control who can access a folder.
- CBitLocker encrypts an entire volume so data is unreadable if the drive is removed, but it does not set per-user folder permissions.
- DVolume Shadow Copy Service provides previous-version snapshots for recovery, not access permissions.
- EThe transaction log restores file system consistency after a crash; it plays no role in restricting folder access.
Now you: objective 2.6 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
After removing spyware that had captured a user's saved browser passwords, a technician educates the end user on stronger sign-in security. The technician recommends adding a hardware security key as a second verification method. Which authentication factor category does this represent?
Sample question 2 of 3
While remediating a ransomware infection, a technician confirms that the workstation's drive still uses hardware-based protection so its data remains unreadable if the drive is removed and installed in another system. Which NTFS-integrated feature provides this protection?
Sample question 3 of 3
After a phishing attack compromised a user's password, a technician recommends multifactor authentication. The user suggests using two different passwords at sign-in instead. Which addition would actually satisfy multifactor authentication requirements?
