CompTIA 220-1202 Exam With Confidence Using Practice Dumps

The ext4 (Fourth Extended Filesystem) is the most widely used default filesystem in modern Linux distributions. It is designed for high performance, scalability, and reliability, and is supported by all mainstream Linux kernels.

A. exFAT is used for cross-platform external drives, not native Linux systems.

B. APFS is Apple ' s proprietary filesystem for macOS and iOS.

D. NTFS is the default filesystem for Windows, not Linux.

Antivirus/antimalware detection depends heavily on its definitions/signatures. If those are outdated, new malware variants may not be recognized. Quentin Docter explains that the “definitions database” is a core antivirus component and that its effectiveness depends on “the frequency of updates and the comprehensiveness of the database signatures.” He adds that new signatures are discovered frequently and added to the database, meaning stale definitions leave gaps.

Docter is also explicit that security software “is not perfect” and that malware may get around it, “especially a new threat (and especially if you haven’t updated your definitions lately).” That statement directly matches this scenario: the software exists, but it failed to detect the infection—most likely because the detection data wasn’t current.

The other answers don’t fit as well: folder permissions and user permissions can limit what malware can change, but they don’t explain why security software didn’t detect it. Port security relates to network access control, not local signature detection. Therefore, Outdated definitions (B) is the best explanation.

If unauthorized or non-standard applications are appearing on systems and users are receiving licensing prompts, it’s likely users are installing software themselves. Removing users from the local administrators group will prevent them from installing software without approval and reduce the likelihood of introducing unapproved or malicious programs.

A. Deploying a PKI helps with secure communications but doesn’t address user software installation rights.

C. Blocking suspicious websites is helpful but doesn’t prevent local installations.

D. Stricter UAC may add prompts but can still be bypassed by admin users.
