There are multiple types of MAC address entries on the switch. Which of the following types of entries can discard messages by matching the source MAC address of the received message, thereby achieving the purpose of filtering out illegal users.
- A . Static MAC address table
- B . Business MAC address table
- C . Dynamic MAC address table
- D . Blackhole MAC address table
As shown in the figure, CE1 sends VPN1 traffic to PE1. After receiving it, PE1 will forward the VPN traffic. Which of the following descriptions of this scenario are correct? (Multiple choice)
- A . The interface on which PE1 receives the data is bound to the VPN1 instance.
- B . PE1 will use the LDP label corresponding to the Next_Hop address of the VPNv4 route as the outer label of the label message
- C . PE1 will check the forwarding table corresponding to the VPN1 instance and obtain the Tunnel ID information
- D . PE1 will search for the corresponding private network label according to Tunnel 1D and push the label header into the message.
Both VLAN aggregation and MUX VLAN are deployed in a certain enterprise network, and the interfaces connecting the switches to the terminals are all Access interfaces.
Then please match PC1~PC4 with the accessible hosts or servers in the scenario shown in the figure one by one (Note: matching the host itself is not allowed, such as PC1 cannot match PC1)
When dealing with a fault in the existing network, a network engineer drew a topology diagram as shown in the figure. All routers run OSPF. Which of the following descriptions about the access path between PC1 and PC2 is correct?
- A . The path from PC1 to PC2 is: PC1-R1-R2-PC2; the path from PC2 to PC1 is: PC2-R2-R1-PC1
- B . The path from PC1 to PC2 is: PC1-R1-R3-R2-PC2; the path from PC2 to PC1 is: PC2-R2-R1-PC1
- C . The path from PC1 to PC2 is: PC1-R1-R2-PC2; the path from PC2 to PC1 is: PC2-R2-R3-R1-PC1
- D . The path from PC1 to PC2 is: PC1-R1-R3-R2-PC2; the path from PC2 to PC1 is: PC2-R2- R3-R1-PC1
As shown in the figure, the OSPF network has the area number marked in the figure. Area 1, Area 2, and Area 3 are all common areas. The 1P address of the R5 Lo0pback0 interface is 10.0.5.5/32, and the interface enables OSPF through the network method. Tac12000 is configured on all routers, and the matching rules are shown in the figure.
In area 0 of R1, R2, and R3, "filter 2000 import" is configured. Which of the following routers‘ routing tables do not have a route entry for 10.0.5.5/32? (Multiple choice)
- A . R2
- B . R3
- C . R1
- D . R4
By default, the cost type of IS-IS routes is narrow mode. In this mode, which of the following is the maximum value of the route cost?
- A . 63
- B . 65535
- C . 6777215
- D . 1023
In the network shown in the figure, IS-IS IPv6 runs between R2, R6, and R3, and the IPv6 address of R6 Looback0 interface is 2000::6/128. Other links run OSPFv3, area 1 is a Stub area, and area 2 is an NSSA area.
IS-IS routes are imported into OSPFv3 on R2 and R3. Which of the following descriptions are wrong? (Multiple choice)
- A . R1 generates an Inter-Area-Router-LSA in Area 2
- B . R3 generates an Inter-Area-Router-LSA in Area 0
- C . R2 generates an Inter-Area-Router-LSA in area 0
- D . R2 generates an Inter-Area-Router-LSA in Area 1
As shown in the figure, when a network engineer is troubleshooting, he draws a schematic diagram of a multicast network. The IGIP version enabled by R1 and R2 is 2, PIM-SM is used as the multicast routing protocol, and other configurations are default configurations. The querier in the multicast network is ().
In the network shown in the figure, R1 and R2 establish an EBGP neighbor relationship through a directly connected interface, and the BFD function is enabled in the BGP process. The BFD parameters are "bfd min-tx-interva1 1000min-rx-interva1 1000 detect-multiplier6". If the IP address of R2’s GE0/0/0 interface is deleted, and the BGP neighbor relationship is checked on R1, which of the following is the longest time for the R1 BGP neighbor relationship to change from Up to Down?
- A . 180s
- B . 6s
- C . 0s
- D . 60s
