220-1202 Dumps with Practice Exam Questions Answers

Comprehensive and Detailed Explanation From Exact Extract:

Operating systems periodically reach a status known as "end of life" (EOL), at which point the developer (e.g., Microsoft, Apple) ceases to provide security updates, patches, or technical support. When this happens, the OS becomes vulnerable and non-compliant with security best practices, which is why organizations typically receive advance notifications from vendors or support teams.

A. Manufacturer support expiration only applies to hardware, not OS patching.

C. Security software may be upgraded or removed, but that does not affect patching the OS itself.

D. The release of a new version doesn’t automatically stop updates for the current version.

Comprehensive and Detailed Explanation From Exact Extract:

When an OS reaches its end of life (EOL), it no longer receives updates or support, including critical security patches.

From the Quentin Docter Study Guide:

“End-of-life means the manufacturer no longer supports the OS with updates or security patches, which exposes systems to vulnerabilities unless upgraded”.

All-in-One Exam Guide adds:

“End-of-life notifications serve as a final warning that continued use of the OS will be insecure and unsupported. It’s crucial for administrators to plan migration”.

The correct answer is B. Kerberos token, because Kerberos authentication relies heavily on precise system time synchronization between clients, servers, and the Key Distribution Center (KDC). Kerberos uses time-stamped tickets to prevent replay attacks, and even small time discrepancies can cause authentication failures.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, Kerberos requires clocks on all participating systems to be synchronized within a narrow tolerance (typically five minutes). If system time is inaccurate, Kerberos will reject authentication requests, resulting in login failures and access denial.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that Kerberos tokens include timestamps to ensure tickets are valid only for a short time window. This security design protects against attackers reusing captured authentication data.

The Mike Meyers / Mark Soper Lab Manual reinforces that time synchronization issues are a common cause of Kerberos-related login problems in domain environments. Services like TACACS+, RADIUS, and WPA do not depend on strict system time synchronization in the same way Kerberos does.

Because Kerberos authentication cannot function correctly without accurate system time, B is the correct answer.

TheDo Not Disturbsetting in Windows Notification settings allows users to suppress all notification banners and sounds during presentations or video calls.

FromTravis Everett – All-in-One Exam Guide:

“Use Windows ‘Do Not Disturb’ to prevent notifications from interrupting full-screen apps like video conferencing.”

Comprehensive and Detailed Explanation From Exact Extract:

A bollard is a sturdy physical barrier—often a steel or concrete post—designed to prevent vehicles or unauthorized individuals from ramming into or entering secure areas of a building. It provides physical security and is commonly used outside entrances to prevent forced entry.

A. PIV (Personal Identity Verification) cards are used for identity access control, not physical blocking.

B. Motion lighting may deter activity but doesn’t physically prevent entry.

C. Surveillance records activity but cannot stop a forced entry.
