How many collision domains are created when you segment a network with a 12-port switch?
A. 0
B. 1
C. 2
D. 3
正解：B
解説：
Each port on a switch creates its own collision domain. Unlike hubs (which extend a single collision domain), switches segment each interface, allowing full-duplex communication and eliminating collisions.
MTCNA Course Material - Ethernet Switching Concepts:
"Each switch port is a separate collision domain. A 24-port switch creates 24 separate collision domains." Rene Meneses MTCNA Study Guide - Collision and Broadcast Domains:
"Switches break up collision domains per port, unlike hubs."
Therefore, a 12-port switch creates 12 individual collision domains.

A client uses a RouterBOARD1000. The clock is configured in '/system clock'. The clock resets to default after each reboot.
Select the best solution for the problem.
A. Configure '/system ntp client' and set a valid and reachable NTP server address
B. Configure '/system ntp server' and set a valid and reachable NTP client address
C. Write a script in '/system script' to set the clock
D. Open the router and ensure the CMOS battery is fine
正解：A
解説：
RouterBOARD devices (such as RB1000) typically do not have a battery-backed hardware clock (RTC). This means the system time resets after each reboot. To keep time accurate, you must configure the router to synchronize with an external NTP (Network Time Protocol) server.
* A.#Inefficient and non-scalable solution.
* B.#The /system ntp server is used to act as an NTP server for others - not for receiving time.
* C.#Correct - You must enable /system ntp client and point to a reachable NTP server to get the correct time on boot.
* D.#Irrelevant - RouterBOARDs do not have CMOS batteries for timekeeping like traditional PCs.
Extract from MTCNA Course Material - Time Synchronization:
"To maintain correct system time, configure NTP client to sync with a public or internal time server after reboot." Extract from Rene Meneses Study Guide - Clock and Scheduler:
"RouterBOARD devices don't have battery-backed RTC. Use the NTP client to update time after reboot." Extract from MikroTik Wiki - NTP Setup:
"Use /system ntp client to sync time. /system clock alone will reset on reboot without NTP."
