On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. The import-route isis level-2 into level-1 command is configured on R2.
In AS 65000, R1, R3, R4, and R6 each establish iBGP peer relationships with R2 and R5. R2 and R5 are Route Reflectors (RRs), and R1, R4, R3, and R6 are clients.
An iBGP peer relationship is established between R2 and R5, and the same cluster ID is configured. The iBGP peer relationships are established using Loopback0. The IP address of Loopback0 on each router is 10.0.X.X/32, where X is the router number.
R1 and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command.

Which of the following statements are true?

• A.The BGP routing table of R5 contains two valid routes to 192.168.1.0/24.
• B.The BGP routing table of R4 contains three valid routes to 192.168.2.0/24.
• C.The BGP routing table of R3 contains one valid route to 192.168.2.0/24.
• D.The BGP routing table of R2 contains three valid routes to 192.168.1.0/24.

If technology migration on the network affects the services running on the live network, strictly follow the preset operation process and risk control measures during the implementation of the technology migration project. Generally, this type of project is defined as a migration project. Which of the following operations performed on the live network belongs to a non-migration project?

• A.Changing the area type of some OSPF routers to the stub area in batches
• B.Changing the levels of IS-IS Level-1-2 routers to Level-1 in batches
• C.Modifying the description of router interfaces in batches
• D.Changing the mode of importing routes to BGP from network mode to import mode in batches

The figure shows the file information on R2. When a network engineer runs the dir | exclude 1 command to view the file information, which of the following files will be displayed?

• A.1.cfg
• B.4.zip
• C.2.cfg
• D.3.dat

On the network shown in the figure, the DHCP server function is enabled on GE0/0/0 of R2, and the address pool is an interface address pool.
When GE0/0/0 and GE0/0/1 of R1 function as DHCP clients, only one interface can obtain an IP address by default.

Options:

• A.FALSE
• B.TRUE

MPLS supports nesting of multiple labels. After receiving an MPLS packet, a device first processes the label next to the Layer 2 header, that is, the top MPLS label.
