The prefix list can match the prefix number and prefix length

The prefix list can be used for packet filtering

The prefix list can be used to filter IP prefixes

Question 13 of 33

14. During the operation of the DHCP protocol, the process from when the client applies to obtain an IP address is:
① The host sends a DHCP Request to request an IP address
② Server sends DHCP Offer message response
③ The host sends a DHCP Discover message to find DHCP

③-②-①-④

①-②-③-④

①-④-③-④

③-④-①-②

Question 14 of 33

15. Which of the following description of how to establish a BFD session is wrong?

BFD sessions can only be established dynamically.

Static configuration of the BFD session refers to configuring the BFD session parameters through the command line, including local identifiers and remote identifiers, etc.

When dynamically establishing a BFD session, dynamically assign a local identifier.

The system distinguishes between static BFD sessions and dynamic BFD sessions by dividing the identifier area.

Question 15 of 33

16. Among the matters needing attention in configuring the Stub area, the correct description is:

The virtual connection can pass through the stub area

If an area is configured as a Stub area, all routers in the area must be configured with Stub area attributes

The backbone area can be configured as a stub area

ASBR can exist in the Stub area

Question 16 of 33

17. Which of the following descriptions about OSPF route aggregation is incorrect?

Any router in OSPF can perform route aggregation operations.

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

Route aggregation refers to aggregating routing information with the same prefix and publishing only one route to other areas.

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

Question 17 of 33

18. When performing source NAT configuration and having no-pat configuration parameters, which of the following statements is correct?

Only the destination IP address is translated

Simultaneous source IP address and source port translation

Only source IP address translation is performed

Perform destination IP address and destination port translation

Question 18 of 33

19. The filter-policy 2000 export is configured in the IS-IS process, which statement about the function of this command is wrong?

It needs to be used in combination with route import, so that only part of the imported external routes can be advertised to neighbors

This command will filter the link state information published externally

If this command is not configured, the device will advertise all the routes imported to S-IS by the external routing protocol by default.

It will restrict the publishing of routing entries generated by the device itself

Question 19 of 33

20. Which of the following description of OSPF neighbor relationship and adjacency relationship is correct?

The adjacency relationship is maintained by OSPF DD packets

OSPF routers must establish an adjacency before exchanging Hello packets

The neighbor relationship is selected from the adjacency relationship and formed to exchange routing information

Not all neighbor relationships can be adjacencies

Question 20 of 33

21. Which of the following descriptions about configuring roaming groups is wrong?

After the AC is enabled with the Master Controller function, it joins the roaming group by default and can manage other ACs

Master Controller is a logical role that can be assumed by any common entity AC

Member ACs need to designate an AC as their own Master Controller

The Master Controller manages each AC through the CAPWAP tunnel

Question 21 of 33

22. Which of the following statements about the address used by AC to establish a CAPWAP tunnel in VRRP hot backup is correct?

The physical address of the primary AC

The physical address of the standby MC

Any address configured in the AC is fine

VRRP virtual addresses of the active and standby ACs

Question 22 of 33

23. The default priority of the VRRP device in the backup group is:

200

150

100

Question 23 of 33

24. Regarding the ABR in OSPF, which is the wrong description?

ABR cannot generate Type 3, Type 4, and Type 5 LSAs

Convert the Type 1 and Type 2 LSAs in the connected non-bone thousand areas into Type 3 LSAs and publish them to the backbone area

The Type 1, Type 2, and Type 3 LSAs in the backbone area of the ABR grid are converted into Type 3 LSAs and advertised to the connected non-bone thousand areas

There are multiple LSDBs on the ABR, and the ABR maintains an LSDB for each area

Question 24 of 33

25. Which of the following descriptions about OSPF default routing is wrong?

The OSPF default route can be issued by the Area Border Router (ABR) to issue Type 3 default LSAs to guide routers in the area to forward packets between areas

When the router has no exact matching route, it can forward the message through the default route

Due to the hierarchical management of OSPF routes, the priority of class 5 and class 7 default routes is higher than that of class 3 default routes

Autonomous System Boundary Router (ASBR) publishes default LSA of type 5 or default LSA of type 7, which is used to guide routes in the autonomous system (AS) to access the outside of the autonomous system

Question 25 of 33

26. Regarding the description of LSA header information in OSPF AS -External – LSA, which is wrong?

Link State ID indicates the destination network address

Forwarding Address is always 0.0.0.0

Advertising Router indicates the Router ID of ASBR

Net mask indicates the network mask of the destination network segment

Question 26 of 33

27. Which of the following is the command to configure the VRRP preemption delay?

vrrp vrid 1 preempt-mode timer delay 20

vrrp vrid 1 timer delay 20

vrrp vrid 1 preempt-timer 20

vrrp vrid 1 preempt-delay 20

Question 27 of 33

28. By default, on a router running IS-IS in a broadcast network, how many seconds does DIS send CSNP messages?

3.3

Question 28 of 33

29. Regarding the description of network address port translation (NAP) and network address translation only (No-PAT), which of the following statements is correct?

No-PAT supports protocol address translation at the network layer

No-PAT only supports protocol port translation at the transport layer

After NATP conversion, for external network users, all packets will only come from the same IP address

NAPT only supports protocol address translation at the network layer

Question 29 of 33

30. When the IPv6 address of the host is configured in the stateless address configuration method, and other parameters except the address are obtained through DHCPv6, how to set the M bit and 0 bit in the RA message?

M=0 0=0

M=1 0=0

M=1 0=1

M=0 0=1

Question 30 of 33

31. Among the routing policy tools commonly used in BGP, the one that can be used to match a specific AS_path is:

filter-policy

ip-prefix

ip as-path-filer

community-filter

Question 31 of 33

32. Which of the following strategies or tools cannot be applied to OSPF?

access-list

prefix-list

route-policy

as-path filter

Question 32 of 33

33. Which of the description about IBGP neighbors and EBGP neighbors is wrong?

If two peers exchanging BGP packets belong to different autonomous systems, then these two peers are EBGP peers

If two peers exchanging BGP packets belong to the same autonomous system, then these two peers are IBGP peers

IBGP peers must be directly connected physically

Two routers running BGP must have IP connectivity to establish a TCP session
