Regarding the port filtering mode of VoiceVLAN, which of the following is correct? (Multiple choice)

A. In normal mode, after the port enters VoiceVLAN, the device no longer checks the MAC address of the message.

B. VoiceVLAN port filtering mode can be divided into two types: security mode and normal mode.

C. In security mode, the device will perform a MAC match check on each packet that is to enter the VoiceVLAN for transmission.

D. By default, VoiceVLAN works in normal mode

[SWA] rrpp domain 1
[SWA-rrpp-domain1] control-vlan 4092
Which of the following information can be obtained?

A. To facilitate network management, you can configure an IP management address on VLAN 4092.

B. The ports on switches SWA, SWB, and SWCRRPP rings that access the RRPP ring need to be added to VLAN 4092

C. All ports on switches SWA, SWB, and SWC need to be added to VLAN 4092

D. The primary ring control VLAN on switches SWB and SWC can be different from that on SWA.

Question #66

Which of the following statements about layer 3 switches is correct? (Multiple choice)

A. The Layer 3 switch actually combines some functions of the Layer 2 switch and router, improving network integration and enhancing forwarding performance.

B. The three-layer switch realizes the functions of VLAN division, two-layer switching within VLAN and inter-VLAN routing.

C. The three-layer switch contains two parts: the layer 2 VLAN forwarding engine and the layer 3 forwarding engine

D. The Layer 3 forwarding engine of a Layer 3 switch is equivalent to the function of a router in a traditional network, using hardware ASIC technology to implement Layer 3 routing forwarding across network segments

Question #67

Which of the following statements about the STP root bridge is correct? (Multiple choice)

A. There is no root port on the root bridge

B. The root bridge refers to the bridge with the highest priority on a Physical Segment.

Question #68

Which of the following statements about the PIM SM registration process are correct?

A. After the RP receives the multicast forwarding traffic from the multicast source, it forwards the traffic to its downstream interface until it reaches the multicast receiver, forming an RPT from the RP to the multicast receiver along the way.

B. When the multicast source initially sends traffic, the DR connected to it will encapsulate several empty Register messages to register with the RP

C. Unlike the PUSH method of PIM DM, in PIM SM, the multicast source starts sending multicast traffic only when there are downstream receivers.

D. After receiving the source registration message for the first time, RP will send a (*, G) join message to the multicast source and establish a (*, G) table entry along the way.

Question #69

Regarding the relationship between RSTP and STP, which of the following is correct statement?

A. RSTP is defined in the old EE802.1 D standard. Its protocol concept is the same as STP, but it has improved the convergence time.

B. RSTP can realize load sharing of data from different VLANs on Trunk links based on STP.

C. Switches running RSTP can work together with switches running STP and improve the convergence time of STP.

D. RSTP has all the functions of STP, but it only uses one type of BPDU

Question #70

As shown in the figure, there is no connection between SWA and SWB at the beginning. SWA and SWB enable RSTP. When the topology is stable, the ports connecting SWA and SWB assume that SWA will become the new root bridge. Which of the following statements are correct? (Multiple choice)

A. The designated port of SWB will continue the P/A handshake process with the downstream switch

B. After receiving the Agreement message sent by SWB, SWA's port E1/0/1 will immediately enter the forwarding state.

C. After SWB completes the synchronization process, it will reply with an Agreement message to SWA, and its port E1/0/1 will immediately enter the forwarding state.

D. During the P/A process, no timer will be used, so the designated port can quickly enter the forwarding state, thereby achieving rapid network convergence.
