Q102. 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

Switch to Master device after about 0.22 seconds

Switch to Master device after about 3.61 seconds

Q104. Regarding the necessity of equipment software upgrade, which of the following options are correct?
(Multiple choice)

New versions of the software continue to add new features

The stability of new versions of the software continues to improve

It is recommended to upgrade to the latest software version immediately

Q105. What is the minimum total length of the address in IS-IS Byte?

Q106. In order to avoid inter-area loops, OSPF regulations do not allow routing information to be published directly between two non-backbone areas, and only allow routing information to be published within an area or between a backbone area and a non-backbone area. Therefore, each area border router (ABR) must be connected to the backbone area.

True

False

Q107. ip ip-prefx List1 index 10 permit 10.1.0.0 24 greater-equal () less-equal 32 means that the first 24 bits of the matching network address are the same as 10.1.0.0, and the network mask length is greater than or equal to 26 and less than or equal to 32. (Use Arabic numerals)

2632

Q108. The command format of the prefix list is ip ip-prefix ip-prefix-name [index index-number] {permit | deny} ipv4-address mask -length [greater-equal greater-equal-value] [ less-equal less equal -value], if only greater-equal is specified but less-equal is specified, which of the following does the prefix range belong to?

[mask-length,greater -equal -value]

[0, greater-equal -value]

Unlimited

[greater-equal -value, 32]

Q109. RPF has the function of preventing multicast forwarding loops.

TRUE

FALSE

Q110. Both policy routing and routing strategy can affect the forwarding process of data packets, but they affect the data packets in different ways. Policy routing is based on policy forwarding, based on the forwarding plane. The routing strategy is based on the control plane, serving routing protocols and routing tables.

True

False

Q111. The four routers run lS-IS and have established adjacency. The area code and the level of the router are marked in the figure. Which of the following statements is correct?

The LSP of R4 does not exist in the LSDB of router R1

The LSP of R3 does not exist in the LSDB of the R2 router

The LSP of R4 does not exist in the LSDB of R3 router

The LSP of R4 does not exist in the LSDB of the R2 router

Q112. In the routing rules of BGP, the manually aggregated route generated by the aggregate command has a higher priority than the automatically aggregated route generated by the summary automatic command.

TRUE

FALSE

Q113. Regarding the description of the characteristics of the routing strategy, the correct one is:

Apply the command policy-based-route

Forwarding according to the routing table based on the destination address

Manual hop-by-hop configuration is required to ensure that packets are forwarded according to policies

Based on the forwarding plane, serving the forwarding strategy

Q114. By executing the command ________, users of different ports in the same VLAN can be completely isolated at the second and third layers and unable to communicate. (Please use English and lowercase letters to complete the command, and the command cannot be abbreviated)

port-isolate mode all

Q115. The routing strategy supports multiple operations on routing attributes. Please match the parameters of the following apply clauses with their functions.

Q116. Which of the following statements about the BFD detection mode is correct? (Multiple choice)

Asynchronous mode is a commonly used BFD detection mode

In query mode, once a BFD session is established, the system will no longer periodically send BFD control packets

Asynchronous detection mode does not support echo function

In asynchronous mode, the systems will send BFD control packets at the negotiated cycle. If a system does not receive the BFD control packets from the peer within the detection time, it will declare the status of the BFD session Down.

Q117. After the STA roams in the WLAN, if it wants to continue to access the home network, it can set the HAC or HAP as the home agent.

TRUE

FALSE

Q118. If you want to realize communication between different protocols, you can only use the method of routing import.

TRUE

FALSE

Q119. ( ) refers to a set of devices that are managed by the same organization and use a unified route selection policy. (Please fill in the English abbreviation, all uppercase)

Q120. Which of the following description of the OSPF default route is false?

OSPF routing can be issued by the area border router (ABR) Type3 default Summary LSA, used to guide the routers in the area to forward packets between areas

The Autonomous System Boundary Router (ASBR) publishes Type5 external province ASELSA, or Type7 external default NSSALSA, which is used to guide the routers in the autonomous system (AS) to access the outside of the autonomous system

When the router does not have an exact matching route, it can forward packets through the default route

Due to the hierarchical management of OSFP routing, the priority of Type5/7 missing routing is higher than Type3 routing

Q121. In the case of without enabling BGP path load sharing, which BGP routes will be sent to BGP neighbors?

All BGP routes learned from all neighbors

Only the best route preferred by BGP

Only routes learned from IBGP

Only routes learned from EBGP

Q122. Regarding the command of OSPF route aggregation, which description is correct? (Multiple choice)

The abr-summary command is a command in the OSPF area view

Advertise is the missing first parameter of the abr-summary command, that is, if the abr-summary command does not specify not-advertise, the default is advertise

not-advertise is the missing first parameter of the abr-summary command, that is, if the abr-summary command does not specify advertisement, the default is not -advertis

The asbr-summary command is a command in OSPF view

Q123. As shown in the figure, in order to ensure the reliability of the WLAN networking, a company has enabled the dual-link hot backup function in the networking.

Which of the following descriptions about active/standby negotiation are correct? (Multiple choice)

If the priority values and load conditions of AC1 and AC2 are the same, the one with the smaller IP address will be given priority

If the value and load of AC1 and Ac2 are the same, the one with the larger IP address will be given priority

The AP will select AC2 as the primary AC

The AP will select AC1 as the primary AC

Q124. When there are two ACs and multiple APs in the WLAN network, the network configuration of active and standby mode is to plan half of the APs to be AC1 as the main AC and AC2 as the backup AC, and the other half of the APs to plan AC2 as the main AC and AC1 as the backup AC, thereby improving the utilization of AC resources.
