質問 # 33
As shown in the figure. When the router uses the 0#PF protocol at the same time. Which BDR is in this network? () (Single-choice question)

A. B. Router B

質問 # 34
Which of the following WLAN security policies support open link authentication?

A. WEP
B. WPA2-802.1X
C. WPA
D. WPA2-PSK

正解：A

解説：
WEP (Wired Equivalent Privacy) supports open authentication, which allows any client to associate with the network without verifying credentials. This form of authentication is considered insecure by modern standards, as it provides minimal protection for network access. WPA and WPA2 rely on pre-shared keys or
802.1X authentication, which are more secure and do not use open authentication.

質問 # 35

質問 # 37
As specified by the RSTP protocol, when a root port fails, which type of port will function as a new root port and enter the forwarding state without any delay?

A. Backup Port
B. Edge Port
C. Forwarding Port
D. Alternate Port

正解：D

解説：
Comprehensive Explanation: In RSTP (Rapid Spanning Tree Protocol), the Alternate Port is the backup path to the root bridge. If the current root port fails, the Alternate Port immediately transitions to the forwarding state, providing a new path to the root bridge with minimal delay. This rapid transition is one of the key improvements of RSTP over the older STP protocol. Backup ports, on the other hand, provide redundancy on the same switch, and edge ports are used to connect directly to end devices.

A. Router C
B. Router A
C. No BDR
D. Router B

B. After a device is reset, an interface card is hot-swapped, or an interface card is reset, dynamic MAC address entries on the device or interface card are lost.
C. After a device is reset, an interface card is hot-swapped, or an interface card is reset, the saved entries on the device or interface card are not lost.
D. You can obtain the number of users communicating on an interface by checking the number of specified dynamic MAC address entries.

Detailed Explanation:With a /30 subnet mask, the valid IP range is 192.168.1.0 - 192.168.1.3:
* 192.168.1.3 is the broadcast address, so it can be a destination.
* 192.168.1.1 and 192.168.1.2 are host addresses.
* 255.255.255.255 is the limited broadcast address, which any device can use to reach all hosts on the local network.

質問 # 51
According to OSI reference model, which layer is responsible for end-to-end error checking and flow control?

A. Data link layer
B. Transport layer
C. Physical layer
D. Network layer

正解：B

解説：
Comprehensive Explanation: The Transport layer (Layer 4) in the OSI model is responsible for end-to-end error checking, flow control, and reliable data transmission. It ensures that data is properly sequenced, without errors, and flow-controlled between the sender and receiver. Protocols such as TCP (Transmission Control Protocol) operate at this layer, providing mechanisms for retransmitting lost packets and maintaining the reliability of a session
