1. The OSPF vlink-peer command is used to configure a virtual connection, which specifies the router-id of the peer.

True

False

2. Regarding the description of OSPF external routing types, which is wrong?

OSPF is divided into the Type 1 of external routing and the Type 2 of external routing.

The cost value of OSPF type 1 external route is only the external cost value of the AS, and the internal cost value of the interconnected AS

The cost of OSPF type 2 external routes is the sum of the internal cost of the AS and the external cost of the AS

Under the same conditions, OSPF's type 1 of external route always takes precedence over the Typle 2 of external route

3. Inject the BGP route by redistributing the command, and its ORIGIN attribute is INCOMPLETE.

True

False

4. When the BGP versions supported by two BGP neighbors are inconsistent, the neighbors will negotiate to use the highest BGP version that both ends can support.

True

False

5. Which of the following types of LSA can carry TAG information for external routes?

LSA5

LSA4

LSA3

LSA2

6. Every DD message has a DD sequence number, which is used for the confirmation mechanism of the DD message. DD contains complete link status information.

True

False

7. In the same LAN, if some IGMP V1 routers exist in the LAN, then IGMP V1 must be configured for all routers in the subnet for normal use.

True

False

8. The function of routing protocol priority is to assign different priorities to the routes discovered by different protocols, so that when a router learns the same route from different routing protocols at the same time, it can have a priority order of selection.

True

False

9. When the Hold Time supported by two BGP neighbors are inconsistent, the neighbors will negotiate to adopt the lowest Hold Time interval that both ends can support.

True

False

10. If the Router Priority is set to 0, then in the OSPF routing domain, the router is allowed to be elected as DR or BDR, but with the lowest priority.

True

False

11. In the BGP routing rules, the route with the higher LOCAL_PREF value takes precedence.

True

False

12. The state where no connection is established between BGP neighbors and no attempt is made to establish a connection is:

Established

Idle

Active

Openconfirm

13. In a network running STP, a variety of topology change information will be sent when the network topology changes. How many types of topology change information are defined in the RSTP network?

One

Two

Three

Four

14. Which of the following description of EGP and IGP is wrong

IGP is a routing protocol that runs inside the AS

EGP is a routing protocol running between ASs

IGP focuses on controlling the propagation of routes and choosing the best route

EGP itself is an ancient agreement

15. On the broadcast or nbma network, not all neighbors will establish adjacency.

True

False

16. Every router running OSPF has a ROUTER ID, which must be published in OSPF.

True

False

17. IGMPv1 only contains two message types: membership query and membership report.

True

False

18. The master-slave relationship of OSPF neighbors is negotiated through DD packets.

True

False

19. IS-IS routers with an interface priority of 0 cannot participate in the DIS election.

True

False

20. The AS border router can be an internal router IR or ABR, and must belong to the backbone area.

True

False

21. What is the wrong description of the LSA header information in the AS-External-LSA of OSPF?

Link state ID indicates the destination network address

Advertising Router represents the Router ID of ASBR

Net mask represents the net mask of the destination network segment

Forwarding Address is always 0.0.0.0

22. IGMP Snooping runs at the data link layer, used to manage, and control multicast groups, and solve the problem of multicast packets broadcast at the third layer.

True

False

23. The ABR in the OSPF complete STUB area does not flood the third, fourth, and fifth type LSAs into the area. Therefore, the ABR in the complete STUB area needs to manually delegate a default route to the area to guide how data packets reach the outside destination of the AS.

True

False

24. The default value of the OSPF DR-PRIORITY command is 1, and the value range is 0-255.

True

False

25. Although the STP protocol can solve the loop problem, the slow convergence of the network topology affects the quality of user communication. RSTP has made many improvements to STP. Which of the following is not an improvement of RSTP to STP?

RSTP's port state specification is divided according to whether the port forwards user traffic and learns MAC addresses, reducing the original 5 port states to 3

The non-root switch running RSTP sends configuration BPDUs at the interval specified by the Hello Timer. This behavior is completely performed by each device independently

RSTP deletes 3 port states and adds 2 new port roles

If a port does not receive the configuration BPDU sent by the upstream device within 4 consecutive Hello Time, the device considers that the negotiation with the neighbor has failed

26. Multiple BGP processes cannot be configured on a router.

True

False

27. The OSPF NBMA network type requires that the routers in the network must select DR and BDR, or they cannot work.

True

False

28. Regarding the description of OSPF route aggregation, which of the following is wrong?

Route aggregation refers to the aggregation of routing information of the same prefix, and only advertises one route to other areas

Through route aggregation, routing information can be reduced, thereby reducing the size of the routing table, and improving the performance of the router

OSPF has two route aggregation methods, ABR aggregation and ASBR aggregation

Any router in OSPF can perform route aggregation operations

29. In the MSTP protocol, each MST INSTANCE uses the RSTP algorithm separately to calculate a separate spanning tree.

True

False

30. Regarding the cost value (Cost) of the routing protocol, which of the following description is incorrect?

Because different routing protocols use different basis for calculating routing costs, it is generally recommended to automatically switch when importing routes.

Because different routing protocols have different basis for calculating routing costs, manual configuration is generally recommended when importing routes.

Generally, the cost values of ISIS and OSPF are based on bandwidth, and the range of values is wide.

Generally, the overhead of RIP is based on the number of hops, and the value range is very small.

31. In the BGP routing rules, the route with the higher MED value is preferred.

True

False

32. In the RSTP protocol, the uplink port of a non-root switch has a port identification parameter. This port identification consists of two parts, namely:

One-byte port priority and one-byte port number

One-byte port priority and two-byte port number.

Two-byte port priority and one-byte port number

Two-byte port priority and two-byte port number

33. In the routing rules of BGP, the priority of the manually aggregated route generated by the AGGREGATE command is higher than the automatically aggregated route generated by the SUMMARY AUTOMATIC command.

True

False

34. Different network types of the OSPF protocol can form an adjacency in the FULL state.

True

False

35. The following is part of the information output by the router Huawei. Which of the following description of this part of information is wrong?

The display pim rp-info command is used to view the RP information corresponding to the multicast group

The RP address is 2.2.2.2.

The priority of RP is 0

The group address is 225.0.0.0
