NO.144 Which of the following description about the Layer 2 Ethernet switch is incorrect?

It is necessary to make certain modifications to the layer 3 header of the forwarded message, and then forward it

Able to learn MAC address

Forward according to the Layer 2 header information of the Ethernet frame

Layer 2 Ethernet switches work at the data link layer

NO.145 The RSTP protocol uses the P/A mechanism to speed up the speed of the upstream port to the Forwarding state, but what is the reason why there is no temporary loop?

Speed up port role election

Through the synchronization mechanism to ensure that no temporary loop occurs

Edge ports are introduced

Shorten the time of Forward Delay

NO.146 Which of the following statements about the role of STP protocol Forward Delay is correct?

Prevent temporary loops

There is a delay when the B1ocking state and the Disabled state are converted

Reduce the time interval of BPDu sending. Improve the convergence speed of STP

Improve the survival time of BPDUs to ensure that the configured BPDUs can be forwarded to more switches

NO.147 What is the main function of the dynamic routing protocol?

Manage routers

Generate IP address

Dynamically generate routing entries

Control router interface status

NO.148 In the network shown in the figure below, which of the following commands can be entered on the router to enable host A to ping host B? (Multiple choice)

RTA: ip route-static 10.0.12.5 255.255.255.252 11.0.12.2 RTB: ip route-static 10.0.12.1 255.255.255.252 11.0.12.1

RTA: ip route-static 10.0.12.5 255.255.255.252 11.0.12.1 RTB: ip route-static 10.0.12.1 255.255.255.252 11.0.12.2

RTA: ip route-static 0.0.0.0 0.0.0.0 11.0.12.2 RTB: ip route-static 0.0.0.0 0.0.0.0 11.0.12.1

RTA: ip route-static 0.0.0.0 0.0.0.0 11.0.12.1 RTB: ip route-static 0.0.0.0 0.0.0.0 11.0.12.2

NO.149 CAPWAP protocol stipulates the communication standard between AC and Ap. Which of the following statements about CAPWAP protocol is correct?

CAPWAP is an application layer protocol based on TCP transmission

In order to establish a CAPWAP tunnel, FIT Ap can only discover AC through broadcast messages

CAPWAP In order to reduce the burden on the AP, a tunnel is used to transmit control messages and data messages at the same time

AP can encapsulate the user’s data message in CAPWAP and forward it by AC

NO.150 For multiple paths to the same destination network, the router needs to select by comparing the magnitude of the Preference value. If the Preference is the same, then select according to the magnitude of the Cost value.

True

False

NO.151 If the network address of a network is 192.168.1.0, then its broadcast address must be 192.168.1.255.

True

False

NO.152 The origin of SDN is the separation of transfer and control. The separation of transfer and control is a way to realize SDN, not the essence.

True

False

NO.153 The information shown in the figure is the port status information displayed on a switch running STP. According to this information, which of the following description is wrong?

The priority of this switch is 0

This network may only contain this switch

This switch may be connected to six other switches

This switch is the root switch in the network

NO.154 Which of the following descriptions about firewalls is wrong?

Firewall can realize user identity authentication

Firewall can realize access control between different networks

Firewall can isolate networks with different security levels

The firewall cannot achieve network address translation

NO.155 The output information of a switch is shown in the figure. Which of the following statements is correct? (Multiple choice)

The GE0/0/2 port of the switch carries VLAN TAG when sending VLAN20 data frames

The user manually created 4 VLANs

The GE0/0/1 port of the switch does not carry VLAN TAG when sending VLAN20 data frames

The GE0/0/1 port of the switch does not carry VLAN TAG when sending VLAN10 data frames

NO.156 In order to realize the network layer function on VLANIF interface, what need to be configured on VLANIF interface? (Multiple choice)

MAC address

Subnet mask

IP prefix

IP address

NO.157 As shown in the figure, the correct description of this network topology is ().

There are 6 collision domains in this network

There are 2 broadcast domains in this network

There are 6 broadcast domains in this network

There are 12 conflict domains in this network

NO.158 The correct description of the information as shown in the figure is ().
[R1]display interface go/0/o
GigabitEthernet0/0/0 current state: Administratively DOWN Line protocol current state: DOWN

The GigabitEthernet 0/0/0 interface was manually closed by the administrator

GigabitEthernet 0/0/0 interface does not enable dynamic routing protocol

The GigabitEthernet 0/0/0 interface is not configured with an IP address

GigabitEthernet 0/0/0 interface is connected to a wrong cable

NO.159 The device port running STP protocol is in Forwarding state. Which of the following statements is correct?

The port not only forwards user traffic but also processes BPDU packets.

The port only receives and processes BPDUs, and does not forward user traffic.

The port will build a MAC address table based on the received user traffic, but does not forward user traffic.

The port not only does not process BPDU packets, but also does not forward user traffic.
