NEW QUESTION 339
A bookstore provides a wired network for customers to learn online. However, one day, it was found that some users could not access the network, and after inspection, it was found that the IP resources of the DHCP address pool had been exhausted. Which of the following is the best way to solve the problem of the moment?
( Single choice questions).

Configure the static ARP binding table

Configure the IPSG

Limits the maximum number of DHCP Snooping binding table entries that the interface allows to learn

True

False

NEW QUESTION 341
Why is BGP an enhanced distance vector routing protocol?

According to the routing rules of BGP routing, the route with lower MED is preferred

BGP uses the ASPATH attribute to record all autonomous system numbers that a route passes through into an AS list, and based on that attribute, routes with shorter AS-PATH are preferred

NEXT_HOP is a recognized mandatory attribute

BGP cannot accept routes that carry a local AS number in the AS_PATH

NEW QUESTION 342
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

NEW QUESTION 343
IS-IS is a link-state routing protocol that uses the SPF algorithm for route calculations. As shown in the figure, at the same time, a certain area has IPV4 and IPV6 and runs IS-IS to achieve network interconnection, of which R2 only supports IPV4 Regarding the topology calculation of the network, which of the following statements is correct?

By default, IPv6 is not supported because R2 Therefore, in the shortest path tree formed by the JPv6 network computation, the path where R1 accesses R4 is: R1-R3-R4

If you want the IPv4 and IPv6 networks to compute the same shortest path tree. The IPv6-enable topology lpv6 command is required to enable the Russian force of IPv6 under the IS-IS process

By default, in the shortest path tree formed by the IPv6 network calculation, R1 accesses R4 as R1-R2-R4, since R2 does not support IPv6 Therefore, R2 will directly drop the IPv6 packet after receiving it, and select the traffic loss

By default, IPv4 and IIPV6 networks are computed separately to form different shortest path trees

NEW QUESTION 344
What is the following correct for the process of registering the source-side DR with RP in PIM-SM?

Encapsulated in the registered message is multicast service data

RP sends a registration stop message as soon as it receives the registration message.

Registered messages are used to build the RPT tree between source DR and RP

Registered packets are multicast packets.

NEW QUESTION 345
What categories can ACLs be divided into?

Advanced ACLs

Two-layer ACL

User-defined ACLs

Basic ACL

NEW QUESTION 346
What are the main reasons why RSTP converges faster than STP?

RSTP increases the variety of port states

RSTP has a smaller overhead

RSTP does not converge based on timer

RSTP has a smaller timer

NEW QUESTION 347
Which of the following scenarios does not require RPF checking?( Single choice questions).

When a router in PIM SM receives multicast traffic when a shared tree is established to an RP in PIM SM

When a pruning message is received in PIM SM

When the RP in PIM SM establishes the source tree to the multicast source

NEW QUESTION 348
IS-IS supports the processing and computation of IPv6 routes by adding ATLPs to carry IPv6 addresses and reachability information.

TRUE

FALSE

NEW QUESTION 349
The MAC address of a PC is 5489-98FB-65D8 The administrator wants this PC to get the specified P address
1921681.11/24 from the DHCP server So the administrator-configured command should be,

dhcp static-bind ip address 1921681.11 mac- address 5489-98FB-65D8

dhcp static-bind ip address 1921681.11 24 mac- address 5489-98FB-65D8

dhcp server static -bind ip address 1921681.112552552550 mac-address 5489-98FB-65D8

dhcp server static-bind ip-address 1921681. 11 mac- address 5489-98FB-65D8

NEW QUESTION 350
MQC, like PBR-can only be called under the device’s Layer 3 interface.

TRUE

FALSE

NEW QUESTION 351
Huawei’s SDN controller using VXLAN technology is fixed?

Agile Controller-Campus

Agile Controller-WAN

Agile Controller-DCN

NEW QUESTION 352
The existing router HWl running BGP is configured with both IBGP neighbors and EBGP tenants. The following descriptions about IBGP Neighbors and EBGP Neighbors are correct?

The router will have an EBGP BGP neighbor from it must be connected directly, otherwise, IBGP-Multi-hop must be configured

The router sends BGP updates learned from its EBGP neighbors to its other IBGP neighbors and EBGP neighbors

IBGP neighbors can establish neighbor relationships through the Loopback interface

The router sends BGP updates learned from its IBGP neighbors to its other IBGP neighbors and EPGP neighbors

EBGP neighbors must be directly connected, otherwise, EBGP-Multi-hop must be configured with

Modify the next hop of locally originating traffic

Pull the traffic of the intranet and the Internet accessing each other on the core switch to the AC device attached to the side

NEW QUESTION 355
The following is an error in the OSPF routing calculation (single choice).

Compared to the PRC algorithm, the ISPF algorithm only calculates the changed leaf nodes when the route changes PRC algorithm to recalculate routes

When the first and second class LSAs on the network change, OSPF uses the ISPF algorithm to recalculate the routes The

OSPF router uses the FULL SPF algorithm to calculate all nodes in the network when initially calculating routes
