NO.283 The following statement about RSTP root protection is correct?

Turning on root protection on the root port takes effect

The port that turns on the root protection receives the RST BDPU with a higher priority and will enter the error-down state

It is recommended that you turn it on on a switch that is at the edge of the network

After opening the root-protected port and receiving the RSTBPDU with a higher priority, if it does not continue to receive the RSTBPDU with a higher priority for a period of time, it will return to the normal forwarding state

NO.284 The following statements about the VRRP protocol are correct (multiple choice).

Both VRRPv2 and VRRPv3 support authentication

VRRPv3 does not support authentication, while VRRPV2 does

VRRPv2 only applies to IPv4 networks, and VRRPv3 only applies to IPv6 networks

The owner of the Master IP address has a VRP priority of 255, and all configurable priorities range from
0 to 254

NO.285 What does RT do in MPLS VPN? Multiple choice questions).

Allows the peer PE to decide which VPNv4 routes to import into a particular VRF

Allows peer PE to decide which VPNv4 routes not to import into a particular VRF

Allows the peer CE to decide which VPNv4 routes to import into a particular VRF

Allows the peer CE to decide which VPNv4 routes not to import into a particular VRF

NO.286 In broadcast networks, elections to DIS begin only after a neighbor relationship has been established

True

False

NO.287 When there are multiple redundant links in an IS-IS network, multiple equivalent routes may occur. Regarding equivalent routing within an IS-IS network, which of the following descriptions is wrong?

When the number of equivalent routes present in the networking is greater than the number configured by the command, and these routes have the same priority, the next hop device System IlD large routes are preferred for load sharing

After you configure the equivalent routing priority, when the IS-S device forwards traffic to the destination segment, it will not use load sharing, but forward the traffic to the next hop with the highest priority

For each of the equivalent routes, you can assign a priority, with the highest priority routes preferred and the rest as backup routes

If load sharing is configured, traffic is evenly distributed across each link

NO.288 Users within a typical VPN can only communicate with each other, not with Internet users, and with Internet.
But VPN individual sites may have access to internet’s needs. The correct description of the implementation of VPN interconnection with internet is ?( Multiple choice questions).

is implemented on the user side, and the CE is directly connected to the Internet. Each user site can be connected to the Internet separately, that is, the CE of each site is configured with a default route to the Internet.

Implementing a complex implementation on PE and having security implications, PE devices may be subject to Dos attacks on the Internet.

Implemented on PE, the PE device issues a default route to the CE to the Internet and adds a default route to the VPN instance routing table pointing to the Internet Gateway o

Implemented on the user side, the implementation method is simple, and the public network and private network routes are isolated, safe and reliable.

NO.289 Because BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors, and routing policies between IBGP neighbors are not valid.

TRUE

FALSE

NO.290 The duplicate address detection feature for NDP in the following description is incorrect?

IPv6 unicast address is called a tentative address after it is assigned to an interface and before it is detected by duplicate addresses

Duplicate address detection is implemented via RS and RA messages

IPv6 duplicate address detection technology is similar to free ARP in IPv4

The interface needs to perform duplicate address detection before enabling any of the unicast IPv6 addresses

NO.291 The Path Selection tool can define multiple entries, which of the following tools will automatically generate a rejection of any entries at the end of the slot

Community -filter

IP-prefix

Route policy

AS-Path- filter

NO.292 How do 8021w and 8021D handle BPDUs?( Confirmed) The

8021D bridge only forwards BPDU packets received from the root bridge

The 8021D bridge does not forward BPDU messages

The 8021w bridge forwards only BPDU packets received from the root bridge

8021w Bridge does not forward BPDU packet

NO.293 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

NO.294 Regarding the DSCP field, the following statement is incorrect: single selection

The DSCP value can be 0, and packets use the default forwarding mechanism when 0

When the value of DSCP is EF, it indicates that the data belongs to the accelerated forwarding class.

In addition to indicating the priority of the data, DSCP can also indicate the probability of data being discarded. The CS class in DSCP divides data into 8 priorities.

NO.295 OSPFv2 is an IGP running on an IPV4 network; OSPFV3 is an IGP running in an IPV6 network IGP, OSPFv3 in the network has a similar LSA type compared to OSPFV2, but the functionality is slightly different, osPFv3LSA type does not include which of the following?

Router-LSA

Network-LSA

Asbr-summary-LSA

AS-external-LSA

NO.296 Is the following description of ospf virtual links correct?

A virtual connection can be established in any area, after which it itself belongs to the region

The virtual connection ip is used as the link address

Virtual links can be used to solve the problem of zone 0 being segmented

The cost of a virtual connection is zero and is the optimal link

NO.297 You need to access the subnets of different VPNs in the VXLAN network , such as information about one subnet Bottom: RT=10:1ORT.100:1000 Export 1000 in EVPN instance and RT-100-100 in VPN instance.
Which of the following can be basketed for another subnet?

All EVPN instances are 1000:1000

In VPN instances, it is 10:10

1000:1000 appears in VPN instances

EVPN implements 1000:1000 export

NO.298 Between two directly attached devices that have established an IBGP neighbor, execute the shutdown command to close the interface of one of the devices. The BGP connection is not immediately disconnected.

TRUE

FALSE

NO.299 The following information about MPLS tags describes the error as ?( Single choice questions).

By default, devices support php features, and the ERAS node that supports PHP assigns a tag value of 3 to the penultimate hop node

When the tag value is 0, the tag must be ejected and the message must be forwarded based on IPv4

The MPLS tag is 4 bytes long and encapsulated between the link layer and the network layer.

If the bottom of the label identifies S=0, it indicates that the label is the bottom label and is directly forwarded to the IP.

NO.300 If you have a LOCAL AREA NETWORK running 8021D Spanning Tree Protocol, the non-root switch does not receive which parameter under the root switch?

MaxAge

Root cost

Forward delay

Hold time

Hello time

NO.301 In VXLAN scenarios, what features can be turned on to reduce flooding of ARP messages between VTEPs?( Multiple select).

Host Information Collection

Local ARP agent

port isolation

ARP broadcast suppression

NO.302 The router connects two EBGP neighbors through two parallel Serial cables, what do you do to achieve bidirectional negative sharing between two EBGP neighbors connected by these two parallel Serial cables? ( Single choice questions).

Without any method, BGP automatically implements load sharing of traffic across different autonomous systems on the available links

Use the Loopback interface to establish an EBGP neighbor relationship, configure EBGP Muti-hop, configure the Loopback interface as the update source, and then use IGP to implement Equivalent path load sharing between Loopback addresses

Configure the EBGP neighbor relationship with the Loopback interface as the update source, and the IGP in each AS needs to introduce two equivalent paths to the loopback address of the EBGP neighbor; And you need to use the command “next-hop?local”

Use the command “ebgp-load-balance” at both ends

To configure an EBGP neighbor relationship with the Loopback interface as the update source, the IGP in each AS needs to introduce two equivalent paths to the EBGP neighbor loopback address ; And the commands “ebgp maxhop” and “next-hop-local” are used
