   • 0x8808
   • 0x8100 
   • 0x8800

2. Which of the following statements regarding VLAN configuration are true? (Choose two.)

   • You can enter the VLAN view and create a VLAN at the same time. 
   • Running undoVLANinvalidates the VLAN but the VLAN still exists. You do not need to recreate the VLAN to use it.
   • You can configure a description string of VLAN. The length of the string is unlimited.
   • If the VLAN ID is not entered when running the displayVLANcommand, all information about the VLAN will be displayed. 

3. Dividing a network using VLANs can (). (Choose two.)

   • Support more network layer protocols
   • Restrict the scope of broadcast domains 
   • Increase the number of collision domains
   • Guarantee data security 

4. By default, the cost of an OSPF interface is calculated based on the bandwidth. The formula to calculate the cost is reference bandwidth/interface bandwidth.

   • TRUE 
   • FALSE

5. All routing protocols can deliver default routes, supporting both forcible delivery and non-forcible delivery.

   • True
   • False 

6. How many multicast IP addresses can be represented by the same multicast MAC address?

   • 1
   • 23
   • 32
   • 24

7. Which of the following statements about RPs are true? (Choose three.)

   • Different group addresses on a PIM-SM network can correspond to different RPs.
   • An RP is the root of an RPT.
   • An RP is elected out of BSRs.
   • All routers on a PIM-SM network must know the location of RPs. 

8. Which of the following routes matches the ACL filter given below?

   “ad number 2001
   rule 0 permit source 1.1.0.0 0”

   • 1.1.1.1/32
   • 1.1.1.0/24
   • 1.1.0.0/16 
   • 1.0.0.0/8

9. What is the maximum number of hosts that a network segment 192.168.2.16/28 can support?

   • 16
   • 8
   • 15
   • 14
   • 7

10. When importing routes discovered by other routing protocols, a routing protocol may need to import only the routes that meet the conditions and set attributes of the imported routes to meet the requirement of the protocol. In such a case, a route-policy can be created.

    • True 
    • False

11. Which of the following protocols support the multicast ASM model? (Choose two.)

    • PIM-SM and IGMPv2 
    • PIM-SSM and IGMPv3
    • BGP and OSPF
    • PIM-DM and IGMPv2 

12. Which interface is connected to the user-side interface?

    • Access interface 
    • Trunk interface
    • Hybrid interface
    • All of the above

13. The Internet Group Management Protocol (IGMP) runs between hosts and their immediately neighboring multicast routers.

    • TRUE 
    • FALSE

14. The link that connects a PC to a switch is ( ).

    • Access Link 
    • Trunk Link
    • Hybrid Link
    • ISL Link

15. Which of the following statements is NOT an advantage of STP?

    • STP can establish redundant links as a backup if the initial link fails.
    • STP can prevent loops
    • STP can prevent broadcast storms
    • STP can save network bandwidth 

16. Which of the following is the port state defined by RSTP?

    • Discarding
    • Learning
    • Forwarding
    • All of the above 

17. Which of the following statements about costs of routing protocols is false?

    • Because different routing protocols have the same basis for calculating route costs, it is recommended to adopt automatic cost converting in route importing.
    • Because different routing protocols have different bases for calculating route costs, it is recommended to perform manual configuration for cost converting in route importing.
    • Costs of OSPF routes is generally based on bandwidth and therefore OSPF cost value ranges is wide.
    • Costs of RIP routes are generally based on hops and therefore the RIP cost value range is narrow.

18. What are the functions of route filtering? (Choose three.)

    • Avoids sub-optimal routes generated during route import.
    • Avoids routing loops.
    • Affects route selection by changing route attributes.
    • Implements accurate route importing and controls route advertisement. 

19. Which of the following methods are supported by OSPF for delivering default routes? (Choose three.)

    • Delivery by an ABR 
    • Delivery by a Backbone Router
    • Forcible delivery
    • Non-forcible delivery

20. Which of the following is the priority value of the DMZ on the USG?

    • 10
    • 50
    • 75
    • 85
