C. SWA can communicate with SWB

D. PCC can communicate with SWB

A. TACACS+ protocol message subject part is all encrypted, high security

B. TACACS+ adopts UDP protocol, high network transmission efficiency

C. TACACS+ protocol uses TCP reliable transmission

D. The TACACS+ protocol message is simple, which can be combined with authentication and authorization, or separated easily

A. The backup group uses virtual MAC mode

B. The backup group vrid is 5

C. The backup group uses real MAC mode

D. The vrid of the backup group is 4

A. The static aggregation group is established between the switch SWA and the switch SWB

B. LACP priority is 0x8001

C. The dynamic aggregation group is established between the switch SWA and the switch SWB

D. Link aggregation port bandwidth size 2G

A. After receiving the multicast packet, the PIM-DM router sends the packet from all interfaces connected to member hosts

B. After receiving the multicast packet, the PIM-DM router sends the packet from all non-RPF interfaces connected to PIM-DM neighbors

C. After receiving the multicast packet, the PIM-DM router sends the packet from all interfaces connected to PIM-DM neighbors

D. Regardless of whether the PIM protocol is running or not, all routers flood multicast packets

E. After receiving the multicast packet, the PIM-DM router sends the packet from all interfaces

A. PCA can communicate with SWB

B. PCA can communicate with PCC

C. PCA can communicate with SWA

D. PCA can communicate with PCB

E. SWA can communicate with SWB

A. RTA and RTB cannot elect the master router of the backup group

B. RTA is the master router of the backup group

C. RTA and RTB are both in VRRP Master state

D. RTB is the master router of the backup group

A. If Hello messages have the same priority, the router with the larger interface IP address will become the DR

B. All PIM routers are members of the 224.0.0.13 multicast group

C. The router sends PIM Hello in multicast mode, the destination address is 224.0.0.13

D. When the DR is elected, the router with the higher priority of the Hello message will become the DR

E. When the router runs IGMPV2, the DR is elected for the shared network segment through the PIMHello message, and the DR serves as the Querier of IGMP

A. IST is a fragment of CIST in the MST region, and the root of IST is the bridge with the highest priority in the MST region

B. One MST region can contain multiple MSTI instances, and different MST regions can contain different MSTI instances

C. One MSTI instance can map multiple VLANs, and the VLAN mapping relationship in different MST regions can be different

D. The root of IST is the bridge closest to the total root in IST

A. RSTP runs between MST regions

B. Switches running MSTP need to exchange a complete mapping relationship between VLANs and instances. If the mapping relationship is different, the switches do not belong to the same MST domain.

C. If the MST domain names configured on the two switches are not the same, the two switches must belong to different MST domains

D. Switches belonging to the same MST domain must have the same VLAN and instance mapping relationship

A. The MAC addresses of SWA and SWB are 00-E0-FC-00-00-11 and 00-E0-FC-11-00-11, and the priority of the two are 32768 and 4096 respectively. When SWA and SWB are used After ring networking and spanning tree protocol is enabled, SWA will become the root bridge

B. Bridge ID is composed of bridge MAC address and priority field. When comparing bridge ID, compare the MAC address first. The smaller MAC address value is preferred.

C. The bridge with the smallest bridge ID in the network will eventually become the root bridge after STP calculation

D. The length of the bridge priority field is 2 bytes, so the value range of the bridge priority is 0-65535

A. BSR controls the collection and dissemination of RP information and is the management core of the PIM-SM domain

B. If there is no BSR in the PIM-SM domain, RP information cannot be diffused, multicast receivers cannot join normally, and multicast traffic cannot be forwarded normally
