The role of telnet.read_all() in Telnetlib is to read all data until EOF. If the echo does not return EOF, it will always be blocked. True. False.

In the network shown in the figure below, all routers run the OSPF protocol, and the link cost value is shown in the figure. What is the cost value of the route entry to the network 10.0.0.0/8 in the RTA routing table?. 70. 100. 20. 60.

The router output information is shown in the figure. Which of the following statements is wrong?. The IP address of the Ethernet0/0/0 interface is 10.0.12.1/24. The MTU value of the Ethgrnet0/0/0 interface is 1480. The physical link of the Ethernet0/0/0 interface is normal. The broadcast address corresponding to the Ethernet0/0/0 interface is 10.0.12.255.

As shown in the figure below, which of the following statement is correct?. Host A can ping host B. Only when the masks of host A and host B are set to always, host A and host B can communicate. The broadcast address of host A and host B are the same. The IP address masks of host A and host B are different, so host A and host B cannot communicate.

ip route-static 10.0.12.0 255.255.255.0 192.168.1.1, which description about this command is correct?. This command configures a route to the 10.0.12.0 network. The priority of this route is 100. If the router learns a router with the same destination network as this route through other protocols, the router will prefer this route. This command configures a route to the 192.168.1.1 network.

What address does 192.168.1.127/25 represent?. Broadcast. Multicast. Network. Host.

What are the characteristics of VLAN based on port?. Add VLAN tags to the data frame according to the IP address carried in the message. Assign VLAN ID according to the protocol type and encapsulation format of the data frame. No need to reconfigure VLAN when the host moves. The host mobile location needs to be reconfigured VLAN.

As shown in the figure below, the network and switch configuration information are shown in the figure. Which of the following statements is correct? (Multiple choice) # interface GigabitEthernet0/0/1 port hybrid pvid vlan 20 port hybrid untagged vlan 10 20 # interface GigabitEthernet0/0/2 port hybrid pvid vlan 10 port hybrid untagged vlan 10 20 #. Data frames on the two links do not contain VLAN TAG. The PVID of the switch GigabitEthernet0/0/1 port is 20. Host A and Host B can be pinged. Host point and host B cannot ping.

In the STP protocol, which of the following factors will affect the election of the root switch? (Multiple choice). The IP address of the switch. Switch interface ID. Switch interface bandwidth port. Switch priority. MAC address of the switch.

The configuration information of a interface of the router is shown in the figure, then which VILAN data packet can this port receive? interface Gigabit Ethernet 0/0/2.30 dot1q terainat1on vid 100 ip address 1o.o.21.1 255.255.255.0 arp broadcast enable. 1. 100. 30. 20.

In a Layer 2 network with redundant links, which of the following protocols can be used to avoid loops?. VRRP. ARP. UDP. STP.

When the switch port receives a data frame that does not carry VLAN TAG, it must add PVID. True. False.

As shown in the figure below, the router uses a sub-interface as the gateway of the host. The IP address of the gateway is 10.0.12.2. Which of the following commands can achieve this requirement? (Multiple choice). Interface GigabitEthernet0/0/0.20 Dotlq termination vid 10 ip address 10.0.12.2 255.255.255.0 Arp broadcast enable #. Interface GigabitEthernet0/0/0.10 Dotlq termination vid 10 ip address 10.0.12.2 255.255.255.0 Arp broadcast enable #. Interface GigabitEthernet0/0/0.10 Dotlq termination vid 20 ip address 10.0.12.2 255.255.255.0 Arp broadcast enable #. Interface GigabitEthernet0/0/0.20 Dotlq termination vid 20 ip address 10.0.12.2 255.255.255.0 Arp broadcast enable #.

The output information of a switch is shown in the figure. Which of the following interfaces can forward data frames with VLAN ID 40 and do not carry tags when forwarding?. GE0/0/2. GE0/0/5. GE0/0/3. GE0/0/4.

Which of the following packet types is used by RADIUS to indicate authentication rejection?. Access-Accept. Access-Request. Access-Challenge. Access-Reject.

NAPT distinguishes the IP addresses of different users through the protocol numbers in TCP, UDP, or IP packets. True. False.

Which of the following authentication methods does not require the user name and password?. authentication-mode local. authentication-mode none. authorization-mode hwtacacs. Authentication-mode hwtacacs.

Telnet is based on TCP protocol. True. False.

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.

How many more bytes are the packets using MPLS label double-layer nesting technology than the original IP packets?. 32. 8. 4. 16.

,:: 1/128 is the IPv6 loopback address. True. False.

Which of the following IPv6 is a global unicast address?. 2001::12:1. FF02::1. FF::02::2E0:FCFF:FEEF:FEC. FEE:FCFF:FEEF:FEC.

In the campus network planning, which of the following ways can business VLAN be divided?. Divide vlan by access member structure. Divide VLAN by business. Divide VLAN by logical area. Divide VLAN by geographical area.
