Remote access management of this switch will not be possible without configuration change. As FastEthernet0/12 will be the last to come up, it will be blocked by STP. More VLANs will need to be created for this switch.

The network administrator normally establishes a Telnet session with the switch from host A. However, host A is unavailable. The administrator's attempt to telnet to the switch from host fails, but pings to the other two hosts are successful. What is the issue?. The switch interfaces need the appropriate IP addresses assigned. Host and the switch need to be in the same subnet. The switch needs an appropriate default gateway assigned. The switch interface connected to the router is down. Host needs to be assigned an IP address in VLAN 1.

Which condition does the err-disabled status indicate on an Ethernet interface?. There is a duplex mismatch. The device at the other end of the connection is powered off. The serial interface is disabled. The interface is configured with the shutdown command. Port security has disabled the interface. The interface is fully functioning.

A network administrator is troubleshooting an EIGRP problem on a router and needs to confirm the IP addresses of the devices with which the router has established adjacency.

The network administrator cannot connect to Switch 1 over a Telnet session, although the hosts attached to Switch1 can ping the interface Fa0/0 of the router. Given the information in the graphic and assuming that the router and Switch2 are configured properly, which of the following commands should be issued on Switch1 to correct this problem?. Switch1(config)# ip default-gateway 192.168.24.1. Switch1(config)# interface fa0/1Switch1(config-if)# switchport mode trunk. Switch1(config)# line con0Switch1(config-line)# password ciscoSwitch1(config-line)# login. Switch1(config)# interface fa0/1Switch1(config-if)# ip address 192.168.24.3 255.255.255.0. Switch1(config)# interface fa0/1Switch1(config-if)# duplex fullSwitch1(confiq-if)# speed 100.

Which three of these show the correct RSTP port roles for the indicated switches and interfaces? (Choose three.). SwitchD. Gi0/2, root. SwitchA, Fa0/2, designated. SwitchB, Gi0/l, designated. SwitchA, Fa0/l, root. SwitchB, Gi0/2, root. SwitchC, Fa0/2, root.

Which command can you enter to verify that a 128-bit address is live and responding?. traceroute. telnet. ping. show ipv6.

What are two reasons that duplex mismatches can be difficult to diagnose? (Choose two.). The interface displays a connected (up/up) state even when the duplex settings are mismatched. 1-Gbps interfaces are full-duplex by default. Full-duplex interfaces use CSMA/CD logic, so mismatches may be disguised by collisions. The symptoms of a duplex mismatch may be intermittent. Autonegotiation is disabled.
