CompTIA Updated 220-1201 Exam Questions and Answers by madiha

The correct answer is D. Data is being throttled .

Data throttling refers to the intentional slowing down of internet speeds by a mobile carrier after a user reaches a certain data usage limit or during network congestion. In this scenario, the employee can still successfully upload files, but the speed has decreased compared to before—this is a classic symptom of throttling.

Why the other options are incorrect:

A. Wireless is turned off

If wireless were turned off, the employee would not be able to upload anything at all. The question clearly states that uploads are still successful.

B. 5G is disabled

Disabling 5G could reduce speeds slightly if the device falls back to 4G/LTE, but it would not typically cause a significant or noticeable degradation unless compared under ideal conditions. It is not the most likely cause.

C. Roaming is turned on

Roaming allows connectivity outside the home network. While it may incur additional charges, it does not inherently cause significant speed reduction in most modern networks. It is less likely than throttling.

Exam Tip (Core 1 220-1201):

Slow but working connection → Think throttling or congestion

No connection → Think disabled wireless or network issues

Final Answer: D. Data is being throttled

The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.

Recommended Replacement Drive:

To minimize performance degradation, the replacement drive should be:

SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).

Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.

In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.

The correct answer is C. Synchronized system clocks .

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Server Services, NTP (Network Time Protocol) is used to synchronize the clocks of computers across a network to a common time source. This is critical for:

Ensuring accurate timestamps for logs and events.

Coordinating scheduled tasks across multiple systems.

Preventing authentication issues in environments that rely on time-based credentials (e.g., Kerberos).

Why the other options are incorrect:

A. Defined network transport protocols: NTP itself is a protocol that uses UDP, but its primary purpose is not defining transport protocols.

B. Enabled print services on the server: NTP does not relate to printing.

D. Defined server options in DHCP: NTP may be referenced by DHCP options, but the act of adding NTP to a server is focused on time synchronization, not DHCP configuration.
