Wrong

QUESTION 141
Auto-negotiate mode is to obtain the maximum interface rate and operating mode, the network administrator configures all Ethernet interface rates of a working switch to 10OMbps, and the operating mode is configured as Full-duplex, when a network card is configured After the auto-negotiate workstation is connected to the switch, the negotiation result is that the interface rate is 10OMbps and the working mode is half-duplex, which of the following explanations is the most reasonable for this phenomenon?

The problem is on the workstation’s NIC, mostly due to the aging of the NIC driver on the workstation , which causes the workstation NIC to learn the interface rate and operating mode configured on the switch

Port rate negotiation is negotiated through the initial port sending FLP , and the operating mode is not negotiated through FLP

STP initializes the port into the blocking state, causing auto-negotiation to fail, so the port should be configured as an edge port

At higher port rates and operating modes, the workstation’s network interface card cannot be configured as auto-negotiate

Auto-negotiation is not configured on the switch, resulting in the switch not being able to send FLP messages to the workstation, causing the workstation to set its own operating mode to Half-duple

QUESTION 142
Which of the following technologies can be used to measure performance based on actual service traffic in Huawei’s CloudWAN solution?

TWAMP

BGP FlowSpec

Telemetry

iFIT

QUESTION 143
The correct description of the extended features of ISIS is ?

When the amount of information in the Link State Protocol data packet PDU to be released by ISIS is too large, the ISIS router will generate multiple LSP shards to carry more ISIS information.

ISIS can choose whether to authenticate incoming SNP and LSP packets

If there are other vendors’ devices on the network and do not support the LSP sharding function, the sharding expansion mode must be configured as Model-1, otherwise the message will not be recognized by other vendors’ devices.

After you enable the LSP shard extension feature of your router, you can use it without restarting the ISIS process.

QUESTION 144
The following statement about the five types of LSAs in OSPF is used to pass external routes, and the following statement about the five types of LSAs is incorrect and flooding in

OSPF networks in non-Stub/NSSA regions

Routers in the same zone as ASBR can calculate external routes by chanting the LSA and the five types of ISAs in the region

The FA address is included in the five types of LSAs, and the FA address is 000 only as reserved for no practical purpose

Configuring the appropriate filtering policy on the ABR or ASBR can filter five types of LSAs

QUESTION 145
Which of the followinguser logout modesare supported by802.1X authentication?

An authentication server forces a user to log out.

A user logs out manually.

An access device forces a user to log out.

An accounting server forces a user to log out.

QUESTION 146
The OSPF3 protocol is a separately developed protocol that differs somewhat from OSPF2 in that OSPFv3 is link-based rather than network segmented, and the following statement is incorrect?(). Single choice questions).

Two OSPF routers connected to the link can establish a neighbor relationship even if their IPv6 address prefixes are different

The routing information obtained by the OSPFv3 router from the neighbor uses the neighbor’s Link-Local address as the next hop in the forwarded packet

For two OSPF routers connected to the link, you can establish a neighbor relationship even if you do not configure a unicast IPv6 address

All OSPFv3 interfaces use the Link-Local address as the destination address of the message

QUESTION 147
The following statement about static VXLAN tunnel configuration is correct?

A BD needs to create an NVE country, and when there are multiple BDs, multiple NVE interfaces must be created

An NVE interface can be associated with multiple VNls, so you can create only one NVE interface when there are multiple BDs

For a VXLAN tunnel, you need to create a corresponding NVE interface, in which you explicitly specify the source IP address and the destination IP address , so there are multiple VXLAN tunnels on the VTEP that must be vE interfaces The destination address of the VXLAN tunnel is specified in the

NVE interface, and multiple VXLAN tunnels can create only one NVE interface

QUESTION 148
Flavors can be used to enhance SRv6 instructions to meet more diversified service requirements. Which of the following are flavors? (Select all that apply)

Penultimate Segment Pop of the SRH (PSP)

Ultimate Segment Decapsulation (USD)

Ultimate Segment Pop of the SRH (USP)

Penultimate Segment Decapsulation (PSD)

QUESTION 149
BGP4+ is running between two routers, and the neighbor relationship is normal, but the BGP routing table of the router on this side does not have a neighbor route entry.

The route entry in the peer BGP route table is non-optimal.

The next hop address of the

BGP route entry is unreachable

Peer ignore is configured on the peer

The peer is configured with active-route-advertise

QUESTION 150
The following description of the characteristics of multi-instance CE is ?

Since the MCE device is already bound to the VPN, there is no need to bind the VPN on the PE connected to the MCE device

The MCE device can determine the source of the routing information according to the interface that receives the routing information, and maintain it in the route forwarding table of the corresponding VP.

MCE is implemented by creating their own routing forwarding tables for different VPNs on the MCE device and binding to the corresponding interface o

Configuring MCE enables a CE to connect to multiple VPNs at the same time, which can not only completely isolate the service between different VPN users, but also reduce the input cost of network equipment.

QUESTION 151
What of the following actions can enable fast failure detection on multicast networks?

Shorten the Holdtime of Join/Prune messages

Reduce the interval at which the interface sends Hello messages

A PIM BFD session is established between neighbors

Reduce the interval between sending Join/Prune messages

QUESTION 152
In the LDP session establishment process, the initiator sends an Initialization message for parameter negotiation. Which message will be sent by the responder if it does not accept negotiation parameters?

Error Notification Message

Initialization Message

Keepalive Message

Hello Message

QUESTION 153
Congestion avoidance technology can prevent congestion on an interface.

TRUE

FALSE

QUESTION 154
In a scenario where a VXLAN tunnel is dynamically established through BGP EVPN, which of the following statements about symmetric IRB forwarding are correct?

Both the ingress VTEP and egress VTEP forward packets based on the Layer 3 forwarding table.

The ingress VTEP forwards packets based only on the Layer 2 forwarding table.

The egress VTEP forwards packets based only on the Layer 2 forwarding table.

When VTEPs forward inter-subnet user communication packets, the VNI carried in the VXLAN header is the L3VNI.

QUESTION 155
Which of the following statements aboutBIER (Bit Index Explicit Replication) and PIM (Protocol Independent Multicast)are correct?

On a BIER-based multicast network, packets sent by the multicast source must be encapsulated with the Bitstring field.

On a PIM-based multicast network, an MDT covering all nodes that multicast traffic traverses needs to be established.

On a BIER-based multicast network, an MDT covering all nodes that multicast traffic traverses does not need to be established.

On a BIER-based multicast network, multicast users must send group join messages hop by hop.

QUESTION 156
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

QUESTION 157
