H12-821_V1.0-ENU Dumps 2022 – New Huawei H12-821_V1.0-ENU Exam Questions

NO.61 On the broadcast or NBMA network, not all neighbors will establish adjacency.

TRUE

FALSE

NO.62 The IGMP protocol runs between the IP host and the multicast router directly connected to it, maintaining the membership of the multicast group

True

False

NO.63 Which of the following statements about stack splitting is wrong?

If the main and standby switches are in two stacking systems after the stack is split, the stack system where the original main switch is located will update the topology and re-designate the standby switch. The original standby switch will be promoted to the master in the new stacking system, and the new standby switch will be elected at the same time

After the stack splits, the MAC addresses of the two stacking systems will definitely change immediately

After the split, multiple stack systems will have the same IP address and MAC address. To avoid network failures, the stack will perform MAD detection. The party that fails the MAD detection competition will close all physical ports except for reserved ports.

If the master and backup switches are still in the same stack system after the stack is split, the slave switches separated from the original master and backup switches will re-elect the master and backup transfer machines due to the timeout of the protocol packets.

NO.64 Route redistribution refers to the operation of only advertising routing information from one routing protocol to another routing protocol.
Which of the following statements about route introduction is correct? (Multiple choice)

When implementing route import, route control can also be deployed to achieve flexible control of correct business traffic

By importing routes, routing information can be transmitted between different routing protocols

The routing protocol itself has anti-loop characteristics, so there is no need to consider loop issues when routes are imported into each other

When implementing route import, you need to pay attention to the routing priority agreements of different vendors may be different

NO.65 OSPF supports multiple processes. Multiple different OSPF processes can run on the same router. They do not affect each other and are independent of each other. The routing interaction between different OSPF processes is equivalent to the routing interaction between different routing protocols.

True

False

NO.66 The following is part of the configuration information of the router Huawei. Which description is wrong about the configuration information?
[HUAWEI] ip as-path-filter 2 permit_200_300
[HUAWEI]route-policy test permit node 10
[HUAWE]-route-policy] if-match as-path-filter 2

Define a Route-Policy named test, the node serial number is 10

Set the AS path filter with sequence number 2 to allow AS200 and AS300 to be included in the routing information

Node 10 of the Route-Policy references AS path filter 2 and defines an if-match clause

The Route-Policy can only be called in the OSPF process

NO.67 Four routers are running IS-IS and have established adjacency relationships. The area numbers and router levels are marked as shown in the figure. If route penetration is configured on the R3 device, what is the cost value from R4 to 0.0.2.2/32?

NO.68 In the OSPF routing domain, in broadcast networks and NBMA networks with at least two routers, one router must be designated as DR and the other as BDR.

TRUE

FALSE

NO.69 There is a message in the BGP protocol that is periodically sent between BGP neighbors to maintain the neighbor relationship. This kind of news is:

Update

Hello

open

Keepalive

NO.70 Which of the following information is carried in the BGP OPEN message? (Multiple choice)

Routing attributes

BGP Router ID

Hold time

Local Autonomous System (AS) number

NO.71 As a network administrator, which of the following protocols can be used for network device configuration? (Multiple choice)

LLDP

SNMP

NETCONF

SSH

NO.72 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

NO.73 Which of the following about the default routing of each protocol is incorrect?

BGP can deliver default routes

ISIS can issue default routes

OSPF cannot deliver default routes

Static default route can be configured

NO.74 The output information of a router is as follows, please match the information on the left with the information on the right.
Router ID of this device: ()
Router ID of the peer device: ()
The interface IP address of this device: ()
City ID to which this device belongs: ()

10.0.1.1|10.0.2.2|10.0.123.1|0.0.0.0

NO.75 Which of the following description about configuring a roaming group is wrong?

After enabling the Master Controller function, the AC joins the roaming group by default and can manage other ACs

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

Member ACs need to designate an AC as their Master Controller

Master Controller manage each AC via CAPWAP tunnels

NO.76 It is possible to prevent the HSB backup channel between the active and standby ACs from being interrupted and unperceivable through mechanisms such as sending active and standby service packets and retransmissions.

True

False

NO.77 As shown in the figure below, the RTC announces 10.1.1.0/24 into BGP, and the RTC is the client of the route reflector RTB, the router RT () will not receive the route entry 10.1.1.0/24 reflected by the RTB. (Use Uppercase)
