QUESTION 112
SSH uses a complete user authentication mechanism to ensure the legitimacy of the logged-in user. Which of the following descriptions of the SSH authentication method is incorrect? (Multiple choice)

No authentication is an optional authentication method

During the password verification process, the server will check the legitimacy of the user’s private key and password. If they are legitimate, the request will be accepted.

If no authentication is used, the server will return verification success in any case

QUESTION 113
After executing the displayinterface Ethernet 1/0/1 command on the switch SWA, the output information is as follows:
[SWA] display interface Ethernet 1/0/1
Ethernet1/0/1 current state: UP
PVID: 10
Mdi type: auto
Link delay is 0 (sec)
Port link-type: trunk
VLAN passing: 1 (default vlan), 10
VLAN permitted: 1 (default vlan), 2-4094
Trunk port encapsulation: IEEE 802.1q
Port priority: 0
what can we learn from the above information? (Multiple choice)

Port Ethernet1/0/1 is a Trunk port that only allows data from VLAN 1 and VLAN 10 to pass through.

When a data frame without a VLAN tag enters port Ethernet1/0/1, it will be tagged with VLAN1.

Data with VLAN1 tag will not be stripped when it leaves port Ethernet1/0/1.

Port Ethernet1/0/1 is a Trunk port, allowing data frames from any VLAN to pass through.

QUESTION 114
The network topology is shown in the figure. STP is enabled on SWA and SWD. which of the following statements about the changes in the status of SWA and SWD ports are correct?

Both SWA’s EO/1 and SWD’s EO/1 need to go through the ForwardDelay delay of the Listening and Learning states to enter the Forwarding state.

The port role of SWD’s EO/1 port changes in the Listening state from a designated port to a root port.

The EO/2 port of SWD changes its port role in the Learning state, from a designated port to an Alternate port.

If the bridge priority of SWD is changed to 0, port EO/2 of SWA will directly enter the Blocking state without the need for the Forward Delay.

QUESTION 115
As shown in the figure, the switch enables RSTP. Which of the following statements about its configuration is correct? (Multiple choice)

The ports that interconnect SWB and SWC can be configured as edge ports to achieve rapid topology convergence

Port E0/3 of SWB and SWC can be configured as an edge port

Ports configured as edge ports can directly enter the forwarding state without delay

If the edge port receives BPDU, it will enter the blocking state

QUESTION 116
In the switching network shown in the figure, VLAN10 is set as Super VLAN on switch SWA, VLAN2 and VLAN3 are Sub VLANs of VLAN10. Port Ethernet1/0/3 is a Trunk port with PVID of VLAN1, allowing all VLANs to pass through. VLAN2~VLAN20 are created on switch SWB, port Ethernet1/0/4 is a Trunk port with PVID of VLAN1, allowing all VLANs to pass through. After setting the IP addresses of each device as shown in the figure, check the MAC address table on SWA, and you can determine that PCC belongs to?

VLAN 1

VLAN 2

VLAN 3

VLAN 10

QUESTION 117

Send access level to access users

Distribute directories that access users can access

QUESTION 118
In PIM-DM networking, which of the following are incorrect descriptions of routers sending Jon messages? (Multiple choice)

After the router RPF interface receives the Prune message, it immediately sends a Join message to the upstream RPF neighbor.

PIM-DM routers do not send Join messages

When a receiver joins the PIM-DM router, it sends a Jon message to the upstream RPF neighbor.

The party that fails the Assert will send a Join message to the winning party

The Join message in PIM-DM is only used to veto the Prune message.

QUESTION 119
Regarding the configuration of bridge priority in spanning tree, which of the following is correct?
(Multiple choice)

The bridge priority is 16 bits in total, ranging from 0 to 65535.

If the switch is not configured with a bridge priority, the default value is 32768

The bridge priority value step is 4096

The smaller the priority value, the lower the priority of the bridge.

QUESTION 120

QUESTION 121
Which of the following descriptions about OpenFlow are correct? (Multiple choice)

Table Miss actions can be customized

OpenFlow uses TCP port 6633

OpenFlow switches are divided into OpenFlow-Only switches and OpenFlow-Hybrid switches

The priority of Table Miss entries is 0

QUESTION 122
Which of the following statements is correct about the fast convergence mechanism of MSTP?
(Multiple choice)

MSTP supports all the fast convergence mechanisms of RSTP

All fast convergence mechanisms of MSTP and RSTP are the same

In MSTP, edge ports can be specified for instances, that is, a port can be an edge port in some instances and a normal port in some instances.

MSTP can work with RSTP switches to achieve fast convergence

QUESTION 123
Which of the following statements about BSR and RP in PIMSM is correct? (Multiple choice)

C-RP routers periodically send announcement messages in multicast mode

After receiving the C-RP announcement message, the BSR calculates the RP to be selected for each multicast group based on the relationship between the RP and the multicast group, and multicasts the calculation result.

BSR is generated through an automatic election process between C-BSRs

When C-BSR is elected, the priority is compared first, and then the IP address of the bootstrap message is compared.

QUESTION 124
In the switching network shown in the figure, VLAN10 is set as Private VLAN on switch SWA, and VLAN2 and VLAN3 are Secondary VLANs of VLAN10; VLAN2-VLAN20 is created on switch SWB, and VLAN20 is set as Private VLAN, and VLAN4 is Secondary VLAN of VLAN20. After setting the IP addresses of each device as shown in the figure, if the local ARP proxy function is enabled on SWA and SWB, and SWA and SWB are allowed to send ICMP packets, execute the command tracert 10.1.1.2 on PCA, and the destination IP address reached by the first hop displayed on PCA is ()

QUESTION 125
Which of the following statements about the PIM SM registration process are correct?

Unlike the PUSH method of PIM DM, in PIM SM, the multicast source starts sending multicast traffic only when there are downstream receivers.

When the multicast source initially sends traffic, the DR connected to it will encapsulate several empty Register messages to register with the RP

After receiving the source registration message for the first time, RP will send a (*, G) join message to the multicast source and establish a (*, G) table entry along the way.

After the RP receives the multicast forwarding traffic from the multicast source, it forwards the traffic to its downstream interface until it reaches the multicast receiver, forming an RPT from the RP to the multicast receiver along the way.

TACACS+ protocol encrypts all the message bodies, which is highly secure.

TACACS+ protocol uses TCP reliable transmission

TACACS+ protocol messages are simple and can be combined with authentication and authorization, or easily separated.

TACACS+ uses UDP protocol, which has high network transmission efficiency

QUESTION 132
In the network connection shown in the figure, SWA and SWB are three-layer switches, running STP+VRRP, and after the initial configuration is completed, SWA is the root of STP and the Master of VRRP. SWC is a two-layer switch connected to the terminal. Which of the following description of the network link failure is correct? (Multiple choice)

When the link between SWB and SWC is disconnected, the port status on the remaining STP links does not change and remains Forwarding.

When the link between SWB and SWC is disconnected, the VRRP Master will remain unchanged and the SWC downstream terminal can still communicate normally.

When only the link between SWB and SWC is intact, SVVA and SWB will become the Master of VRRP, and the lower end of SWC can communicate normally with the gateway.

When only the link between SWB and SWC is intact, the VRRP Master will remain unchanged, but the SWC downstream terminal cannot communicate with the gateway.
