Question 2

As shown in the figure, initially SWA is connected to SWB through E0/1, and SWB is connected to SWC through port E0/2. SWA and SWC are not directly connected. After enabling STP and waiting for its convergence, connect SWA to SWC, which leads to the switch port The change of STP status, the correct description of this change is

A. SWB port E0/2 will go directly to Blocking state from Forwarding state B. Both SWB port E0/2 and SWC port E0/2 will stay in the Listening state and the Learning state for one Forward Delay period. C. Both SWA port E0/2 and SWC port E0/1 will stay in the Listening state and the Learning state for one Forward Delay period. D. SWC port E0/2 will go directly to Forwarding state from Listening state

Question 3

The following statements about the PIM SM registration suppression timer are correct (choose one or more)

A. The DR router of the multicast source will maintain a registration suppression timer. If the timer expires, the DR will unicast multicast source registration messages to the RP B. To prevent the registration suppression timer from expiring, the DR will send the Register message encapsulating the multicast data to the RP before the timer expires C. After the RP receives the registration message from the DR, it will send a registration stop message and update the local (S, G) and (*, G) entries D. After receiving the registration stop message, the DR will update the registration suppression timer and continue to send data in multicast mode

Question 7

The IP address of the host PCA is 40.1.1.1, and the MAC address is 0011.1111.1111. The PCA is connected to the GigabitEthernet1/0/1 port of the switch SWA. The following commands are configured on the switch SWA:
[SWA]vlan 10
[SWA-vlan10]quit
[SWA]vlan 20
[SWA-vlan20]protocol-vlan ipv4
[SWA-vlan20]quit
[SWA]vlan 30
[SWA-vlan30]quit
[SWA]mac-vlan mac-address 0011-1111-1111 vlan 30
[SWA]vlan 40
[SWA-vlan40]ip-subnet-vlan ip 40.1.1.0 255.255.255.0

Question 8

In the network connection as shown in the figure, SWA/SWB/SWC are in the same MSTP domain and configure the same domain configuration
stp region-configuration
region-name h3c
instance 1 vlan 10
instance 2 vlan 20
instance 2 vlan 30
active region-configuration
The ports of the three interconnected links are all Access and belong to the VLAN as shown in the figure. The three switches respectively create the VLAN virtual interface corresponding to the Access link and run OSPF on the virtual interface. The IP address of the VLAN virtual interface is assigned as follows:
SWA: vlan-interface 10 (192.168.10.1); vlan-interface 30 (192.168.30.1)
SWB: vlan-interface 10 (192.168.10.2); vlan-interface 20 (192.168.20.1)
SWC: vlan-interface 20 (192.168.20.2); vlan-interface 30 (192.168.30.2)
When the interconnection ports are all UP and the STP and OSPF calculations are completed, the following descriptions about network connectivity are correct:

A. Two of the three switches cannot establish OSPF neighbor relationships B. Three switches can establish OSPF neighbor relationships in pairs C. Among the 6 interconnected addresses, at least two interconnected addresses are mutually unreachable D. All interconnection addresses of the three switches are mutually reachable

Question 9

Regarding loop protection, the following statements are correct

A. Link congestion or single link may cause loops B. In MSTP, this function is valid for root port, alternate port and backup port C. If the role of the root port changes, it will become the Discarding state, without forwarding packets, so that no loop will be formed in the network. The Discarding state will be maintained until the port receives the BPDU again and becomes the root port again. D. After the loop protection function is activated, when the BPDU saved on the port ages, the loop protection takes effect

Question 10

The following statements about the DR election process of the PIMSM shared network segment are correct:

A. After electing the DR, elect the BDR again. When the DR fails, the BDR quickly takes over its work to ensure the normal forwarding of multicast traffic B. When electing a DR, first compare the priority of Hello messages. The router with the highest priority of Hello messages will become the DR of the network segment. C. If the priority of Hello messages is the same, the router with the largest shared network segment Routerid will become the DR of this network segment D. If the priority of the Hello message is the same, the router with the larger IP address of the shared network segment interface will become the DR of the network segment

Question 12

Regarding the description of Isolate-user-vlan technology and Super VLAN technology, the following is correct

A. Isolate-user-vlan is a Layer 2 VLAN technology, so switches that support isolate-user-vlan technology are Layer 2 switches B. SuperVLAN is a three-layer VLAN technology, so all switches that support Super VLAN technology are three-layer switches C. SuperVLAN technology is also called VLAN aggregation: the main purpose is to solve the waste of IP addresses or insufficient number of VLAN interfaces
