NEW QUESTION 152
In the description of the MAC address spoofing attack, the error is ? Radio

Mac address spoofing attacks cause the switch to learn the wrong mapping of Mac addresses to IP addresses

A MAC address spoofing attack causes the data that the switch is sending to the correct destination to be sent to the attacker

MAC address spoofing attacks primarily exploit the switch Mac address learning mechanism

An attacker can perform a MAC address spoofing attack by sending a forged source Mac address data frame to the switch

VRRPv2 is only available for IPv4

VRRPv3 does not support authentication

VRRPv2 supports authentication

VRRPv3 is only available for IPv6

NEW QUESTION 155

TRUE

False

NEW QUESTION 156
The following is the correct statement about the LSA of OSPFv3?

Inter-AreaPrefix-SA’s LinkStatelD contains the prefix

Router-LSA and Network-LSA does not contain routing information

When the Intra-AreaPrefixLSA’s ReferencedLinkStateType-2, referencedLinkStatelD contains the interface to DR ID

Inter-AreaPrefirLSA also contains LinkLocal information file

NEW QUESTION 157
What is the following description of MPLS incorrect?

The length of the MPLS tag is 20 to 20 for packet forwarding.

The tag space range of dynamic signaling protocols such as LDP, M P-BGP is 16 to 1023

When using the TTL processing method of Pipe mode, the IP packet transmits the TTL of the IP packet over the IPLS network. The value is only minus 1 for the MPLS in and out nodes.

MPLS supports multi-layer label nesting, and the S bit value of the innermost label is 1.

NEW QUESTION 158
The following is a description of how BFD sessions are established, which is the wrong one

The system distinguishes between static BFD sessions and dynamic BPD sessions by dividing the identifier area Dynamically assign this landmark identifier

BFD sessions can only be established dynamically

Static configuration of BFD session refers to manual configuration of BFD session parameters through the command line, including local identifiers and remote identifiers

NEW QUESTION 161
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.

NEW QUESTION 162
The following statement about VXLAN gateways is incorrect

Layer 2 gateway: Used to solve the problem of tenant access to the VXLAN virtual network, it can also be used for subnet communication of the same VXLAN virtual network.

Layer 3 gateway: Used for cross-subnet communication of VXLAN virtual networks and access to external networks.

VXLAN Layer 3 gateways can be divided into centralized gateways and distributed gateways.

Layer 2 gateway and VPN instance binding.
