As shown in the figure, a network administrator implements MPLS data forwarding by configuring static LSP. Below the topology diagram is the administrator’s packet capture information of a certain device. Which of the following descriptions of this information are correct? (Multiple choice)
- A . If the packet capture device is R3, then R3 will perform IP forwarding on the packets from PC1 to PC2.
- B . PC1 pings PC2
- C . The message from PC1 to PC2 is forwarded based on the MPLS label in the MPLS domain.
- D . The message from PC2 to P01 is forwarded based on the IP header in the MPLs domain
As shown in the figure, S73 is the user gateway and DHCP Relay in the network. The administrator plans to deploy the DHCP Snooping function on S73 to prevent DHCP attacks. Which of the following commands does not need to be configured on ST3?
- A . [SW3-GigabitEthernet0/0/1] dhcp snooping enable
- B . [SW3-GigabitEthernet0/0/2] dhcp snooping enable
- C . [SW3] dhcp snooping enable ipv4
- D . [SW3-GigabitEthernet0/0/3] dhcp snooping trusted
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
The AS-path attribute is a private attribute of the BGP protocol. The "if-match as-path-filter" command is only valid for BGP routes.
- A . True
- B . False
In the OSPF network shown in the figure, the area numbers are marked in the figure, where area 1 is the Stub area, area 2 is the Totally NSSA area, and area 3 is the NSSA area. If R5 introduces an external route 10.0.5.5/32, which of the following routers do not have a route entry for 10.0.5.5/32 in their routing tables? (Multiple choice)
- A . R2
- B . R6
- C . R4
- D . R3
Advanced ACL defines rules based on information such as source IP address, destination IP address, IP protocol type, TCP source/destination port, UDP source/destination port number, etc. Using routing policies to call advanced ACL can achieve BGP routing control.
- A . True
- B . False
In the OSPFv3 network shown in the figure, routers are interconnected using Ethernet links.
By default, the number of DRs in this network is which of the following?
- A . 6
- B . 9
- C . 8
- D . 7
Trap information is a notification generated by the system when a fault is detected. It mainly records system status information such as faults. If the network administrator wants to view Trap information through the command line, the SNMP agent function must be enabled first.
- A . True
- B . False
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.
in the scenario shown in the figure, which of the following IP addresses can PC3 access? (Multiple choice)
- A . 10.1.1.2
- B . 10.1.1.100
- C . 10.1.1.15
- D . 10.1.1.1
