What happens to switch ports after the VLAN to which they are assigned is deleted
Show How is traffic routed between multiple VLANs on a multilayer switch?Traffic is routed via physical interfaces. Traffic is routed via internal VLAN interfaces. Traffic is broadcast out all physical interfaces. Traffic is routed via subinterfaces. ¡ Correcto ! ¡ Incorrecto ! Multilayer switches can perform inter-VLAN routing by the use of internal VLAN interfaces. External physical interfaces can receive traffic but are not necessary for routing functions. When routing between VLANs, any broadcast traffic that is received on a VLAN would remain on ports that are members of that VLAN. Subinterfaces are not usable for inter-VLAN routing on multilayer switches. Refer to the exhibit. A router-on-a-stick configuration was implemented for VLANs 15, 30, and 45, according to the show running-config command output. PCs on VLAN 45 that are using the 172.16.45.0 /24 network are having trouble connecting to PCs on VLAN 30 in the 172.16.30.0 /24 network. Which error is most likely causing this problem?The GigabitEthernet 0/0 interface is missing an IP address. The wrong VLAN has been configured on GigabitEthernet 0/0.45. The command no shutdown is missing on GigabitEthernet 0/0.30. There is an incorrect IP address configured on GigabitEthernet 0/0.30. ¡ Correcto ! ¡ Incorrecto ! The subinterface GigabitEthernet 0/0.30 has an IP address that does not correspond to the VLAN addressing scheme. The physical interface GigabitEthernet 0/0 does not need an IP address for the subinterfaces to function. Subinterfaces do not require the no shutdown command. How are IP addressing designs affected by VLAN implementations?Each VLAN must have a different network number Each VLAN must have a different subnet mask. VLANs do not use a broadcast address. VLANs do not support VLSM. ¡ Correcto ! ¡ Incorrecto ! Each VLAN requires its own network number, broadcast address, and valid IP addresses because each VLAN is a separate network. IP addressing schemes are frequently designed with the VLAN numbers as part of the design. Refer to the exhibit. A network administrator is verifying the configuration of inter-VLAN routing. Users complain that PC2 cannot communicate with PC1. Based on the output, what is the possible cause of the problem?The encapsulation dot1Q 5 command contains the wrong VLAN. Gi0/0 is not configured as a trunk port. The command interface GigabitEthernet0/0.5 was entered incorrectly. The no shutdown command is not entered on subinterfaces. There is no IP address configured on the interface Gi0/0. ¡ Correcto ! ¡ Incorrecto ! In router-on-a-stick, the subinterface configuration should match the VLAN number in the encapsulation command, in this case, the command encapsulation dot1Q 10 should be used for VLAN 10. Since subinterfaces are used, there is no need to configure IP on the physical interface Gi0/0. The trunk mode is configured on the switch port that connects to the router. The subinterfaces are turned on when they are added. Refer to the exhibit. Communication between the VLANs is not occurring. What could be the issue?The Gi1/1 switch port is not in trunking mode. The wrong port on the router has been used. Default gateways have not been configured for each VLAN. A duplex issue exists between the switch and the router. ¡ Correcto ! ¡ Incorrecto ! The subinterfaces could not have an IP address unless the encapsulation mode had been configured. When a duplex issue exists, communication can still occur, but it is at a slower than optimum rate. Under which two occasions should an administrator disable DTP while managing a local area network? (Choose two.)Por favor, selecciona 2 respuestas correctas on links that should not be trunking when a neighbor switch uses a DTP mode of dynamic auto on links that should dynamically attempt trunking when a neighbor switch uses a DTP mode of dynamic desirable when connecting a Cisco switch to a non-Cisco switch ¡ Correcto ! ¡ Incorrecto ! Cisco best practice recommends disabling DTP on links where trunking is not intended and when a Cisco switch is connected to a non-Cisco switch. DTP is required for dynamic trunk negotiation. Which two events will cause the VTP revision number on a VTP server to change? (Choose two.)Por favor, selecciona 2 respuestas correctas adding VLANs changing the VTP domain name rebooting the switch changing the switch to a VTP client changing interface VLAN designations ¡ Correcto ! ¡ Incorrecto ! Changing the VTP domain name always resets the VTP revision number to 0. This is an important step in adding switches to an existing VTP domain no matter what VTP mode the switch uses. Which command should the network administrator implement to prevent the transfer of DTP frames between a Cisco switch and a non-Cisco switch?S1(config-if)# switchport mode access S1(config-if)# switchport mode dynamic desirable S1(config-if)# switchport nonegotiate S1(config-if)# switchport mode trunk S1(config-if)# switchport trunk allowed vlan none ¡ Correcto ! ¡ Incorrecto ! To prevent DTP frames from being generated by the interface of a Cisco switch, use the S1(config-if)# switchport nonegotiate command. DTP is Cisco proprietary and not usable by other vendors. Where is the vlan.dat file stored on a switch?in NVRAM in RAM on the externally attached storage media or internal hard drive in flash memory ¡ Correcto ! ¡ Incorrecto ! Normal range VLAN configurations are stored within a VLAN database file, called vlan.dat, which is located in the flash memory of the switch.
