True

False

NEW QUESTION 239
In order to configure M4, you first need to define a RADIUS server, which is defined as follows:
Huawei]radius-server template EXAM

NEW QUESTION 240
There are many ways to establish a cluster on a box switch, what methods does Huawei frame switch support to establish a cluster?

Set up via a cluster card on the motherboard

Establish

through the cluster daughter card on the interface board. Establish

through the service interface on the interface board Established by switching the cluster card on the network board

NEW QUESTION 241
There is an existing router interface serial 0 in OSPF area 1 , well will interface Serial 0 is set to silent interface. So what is the impact of this setting?

OSPF establishes usable adjacencies through this junction

OSPF does not join the routes learned from the connector to the local routing table

OSPF does not establish any adjacency relationships through the junction

OSPF receives a route update answer from the neighbor.

NEW QUESTION 242
A router Router LSA is shown in the figure, and the error in the following statement is ?

This router supports external routing ingestion

This router is a DR

The Router ID of this router is 100121

This router has established an adjacency relationship

NEW QUESTION 243
In different scenarios, RSTP provides different protection functions, and the wrong statement about this statement is

The root protection feature is enabled for the specified port, and its port role can only remain as the specified port

When the anti-TC-BPDU packet attack feature is enabled, the number of times the switching device processes IC BPDU packets per unit time is configurable

after the BPDU protection function is enabled on the switching device, if the edge port receives RST BPDU, the edge port will be set to a non-remote port and the spanning tree calculation will be re-performed

Start the specified port of root protection, when the port receives a better RSTBPDU, the port will enter the Discarding state and is no longer forwarding packets. If the port does not receive a better RSTBPD for a period of time then automatically revert to the normal Forwarding state

NEW QUESTION 244
The command to configure VRRP preemption delay is ?

vrrp vrid 1 preempt-mode timer delay 20

vrrp vrid 1 preempt-delay 20

vrrp vrid 1 preempt-timer 20

vrrp vrid 1 timer delay 20

NEW QUESTION 245
There can be multiple nodes under a route -policy, different node numbers are identified by nodes, and each node can have multiple if-match and apply clauses, which of the following descriptions are wrong ?

The relationship between the if-match clauses under each node is “and”

The relationship between different nodes is an “and” relationship

There is an “or” relationship between different nodes

The relationship between the if-match clauses under each node is “or”

NEW QUESTION 246
What does IPV6 enable topology ipv6 mean under IS-IS protocol view?

Does not have any meaning

SPF calculation for IPv6 is not supported

SPF calculation is performed separately in the topology of IPv4 and IPv6,

IPv4, IPv6 using the same topology for SPF calculation

NEW QUESTION 247
Without dividing the zone, is the following description of the link state routing protocol correct?

Each router establishes a topology for the entire floodplain

Each router learns route entries directly from the route update and adds them to the routing table

Routers in the flood domain may receive the same link state information repeatedly

Routers throughout the flood domain have the same database of wrong-state states

The router will send all the mis-routing status information from one neighbor to all other neighbors to ensure the synchronization of the database

NEW QUESTION 248
The data results of a router are as follows, and the analysis conclusion is correct (single choice).

The GEO/0/0 port of the R3 is in a different region than the neighbor

The R3 router’s Eth0/0/1 enables both IPv4 and IPv6 ISIS

R3 is on the link where Eth0/0/0 is Eth0/ 1 of the LEVEL-1 and Level-2 DISC

R3 routers Circuit-level is Level-1-2

NEW QUESTION 249
Regarding the description of the BGP neighbor, the error is:

BGP routers that support autodiscovery neighbors

BGP establishing neighbors must be configured with MD5 authentication

BGP needs to establish a UDP connection before establishing a neighbor

BGP to establish a neighbor relationship needs to first interact with the link state information

NEW QUESTION 250
The following statement about IPSec VPN is correct ?qo

Two routers establish an IPSec VPN in brutal mode, so that the two devices can interact with a minimum of 4 messages to establish a tunnel.

Brutal mode can support NAT traversal, while main mode does not support NAT traversal.

The two routers can establish OSPF neighbor relations and exchange intranet routes through the IPSec VPN tunnel

The two routers establish IPSecVPN in main mode, and from the 5th packet (included), the payload’s data will be encrypted.

NEW QUESTION 251
What are the following techniques for improving MPLS BGP VPN reliability?( Multiple choice question)

dual home networking is configured at the access layer

VPN FRR

VPN GR Private IP routing between

PE-CE FRR

NEW QUESTION 252
As shown in the figure, private network routing information is exchanged between PEl and PE2 and their respective CE via OSPF, and the same is configured on PEI and PE2 Domain D.
When routing is introduced from BGP to OS9PF on PE2, the following limited types of LSAs may be passed to E2?

Type7 LSA

Type5 LSA

Type3 LSA

Type1 LSA

NEW QUESTION 253
In an Hw IP multicast network-which of the following multicast features are associated with (*, G) table entries? ( Multiple select)

Dense mode

Source tree

Sparse mode

PIM bidirectional

Share the tree

Dense Tree

NEW QUESTION 254
IsIS IPv6 cost 50 is configured under the interface, and the meaning of the command is ?

The LEVEL-1 and Level-2 costs of the interface’s IS-IS IPv6 are 50

The LEVEL-1 and Leve1-2 costs of the INTERFACE’s IS-IS IPv6 are both 60

The LEVEL-2 cost of the interface’s IS-IS IPv6 is 50

The LEVEL-1 cost of the interface’s IS-IS IPv6 is 50

NEW QUESTION 255
When an administrator configures VRRP, which of the following is not required?

Preemption mode

Priority of the virtual router

Preemption delay

Virtual IP address

NEW QUESTION 256
Regarding IPv6 over IP4(19) road, the following statement is correct

The 6to4 automatic tunnel requires the use of a specific IP6 address segment, and the assigned address segment is preceded by 3ffe::/16

When configuring manual tunneling on the VRP platform, a Tunnel interface is generally created; When configuring automatic tunneling, a Vrua-Template interface is usually created

The ISATAP tunnel determines the destination IPV4 address of the tunnel based on the destination IP6 address.

All automatic tunnels encapsulate data in the same way.

Automatic tunneling has great advantages over manual tunneling, and manual tunneling will be phased out
