Q252. The following statement about the security alliance SA in IPSec is incorrect

SA is uniquely identified by a triple that includes the security parametric reference SPI (Security Parameter Inder), the source IP address, and the security protocol number (AH or ESP)

Use the display ipsec command to view the encryption algorithm used with another IPSec peer, the traffic of interest, and so on.

IPSec only supports encrypting data using symmetric encryption algorithms.

A two-way SA must exist between IPSec peers to establish an IPSec VPN connection

Q253. ?? Route? Policy??:ip community-filter Ipermit 100: 1 ip as-path-filter 2 permit ^I00$ route-policy test permit node 10 if-match communityfilter 1 if-match as-path-filter 2 apply as-path 200 Is the above configuration description correct?

The BGP route matches the above only if the BGP route carries a community attribute value of 100:1 or if the AS PATH is 100 route one policy. The AS-one PATH attribute that matches the route is changed to 200

The BGP route matches the above only if the BGP route carries a community attribute value of 100:1 and the AS-One PATH is 100 route policy?. The AS-PATH nature of the matching route is changed to 200

Only if the BGP route carries an AS-PATH of 100, the BGP route matches the route one policy above. The AS-one PATH attribute that matches the route is changed to 200

As long as the BGP route carries a community attribute value of 100:1, the BGP route matches the route-policy above. The AS-PATH attribute of the matching route is changed to 200

Q254. The correct description of configuring BGP4+ is that

BGP4+ does not support route reflectors.

The next hop of a BGP4 route can use the Link-Local address.

BGP4 configures the reflector, the role positioning of the reflector and the client needs to be consistent with the configuration of BGP4

BGP4 specifies p

BGP4+? Router-ID? BGP4? Router-ID-??

Q255. Which of the following is the benefit of VLAN aggregation?

Implements isolation of broadcast domains between Sub-VLANs

Reduce the waste of IP addresses

Increased number of available VLANs

Increased flexibility in addressing

Q256. The multicast protocol that can generate multicast distribution trees is?

IGMPv2

BGP

OSPF

PIMV2

Q257. The correct statement about the VRRP protocol version is?

VRRPv2 is only available for IPv4

VRRPv3 does not support authentication

VRRPv2 supports authentication

VRRPv3 is only available for IPv6

Q258. QinQ technology is a technology that extends the VLAN space by adding a layer of 8021Q tag messages to the extended VLAN.
The function of space, the following statement about QInQ is mispronounced?

basic QinQ is implemented based on the interface orientation

QinQ increases the number of VLANs to 4095*4095

Flexible QinQ can be based on different inner layerS Tag and different outer layers of Tag, for user VL. The division of AN is more granular

QinQ technology enables private VLANs to pass through the public Network

Q259. If a Huawei switch runs the RSTP protocol, when will the BPDUs on a port on the switch be aged?

On the interface, RSTP does not age BPDU

After more than 6 seconds

After Ma ge times out

After Hello time times out

after the Forward Delay timeout

Q260. What are the three ways to send IPv4 messages?

broadcast

Unicast

Multicast

Any broadcast

Q261. Each DD message has a sequence number for data confirmation, and a DD sequence number is 2 bytes long

True

False

Q262. In an MPLSVPN network, when a packet enters the Internet and is forwarded, it is encapsulated with two layers of MPLS tags, and the processing of the packet in the following options is described correctly?

The penultimate hop device receives packets with an outer label of 3

The Egress PE appliance receives an UNlabeled IP packet

The Egress PE device correctly sends packets to the appropriate VPN

based on the inner tag. The packet pops up the outer label on the penultimate hop device and forwards it to the Egress PE device

Q263. The following description of IGMPv1 and IGMPv2 is correct? (Multiple select).

IGMPv2 message types include member departure packets

IGMPv2 does not support specific group queries

IGMPv1 supports universal group queries

The IGMPv1 message type does not contain members leaving the packet AD

Q264. D Class IP address range 239000-239255255,
What does 255 do? Radio

SSM multicast address, the multicast address segment is valid for the whole network

Any legitimate multicast traffic and multicast application can adopt this address

Locally managed multicast address, which is valid only locally

Link-local multicast address, where traffic that uses that address includes network control messages and that address range is only the multicast address segment used by the routing protocol

Q265. Which of the following scenarios send free ARP messages? (Multiple choice questions).

After the VRRP protocol master and standby role election is completed

The DHCP client receives an acknowledgment message from the server after it sends it

When a new host configured with an IP address is connected to the network

When a host connected to the switch issues a Ping message.

Q266. The following description of ISIS’s routed infiltration is correct? (Multi-select)

ISIS routing penetrates | Can be used in Pv6 environments.

Route penetration for ISIS can be deployed on Level-1 routers.

Route penetration for ISIS does not include aggregated routes.

Route penetration of ISIS does not cause neighbor concussions.

Route infiltration of ISIS is used to prevent routing loops.
