Which two statements are correct with respect to SVI inter-VLAN routing? (Choose two.) There is no need for a connection to a router. Switching packets is faster with SVI. SVIs can be bundled into EtherChannels. SVIs eliminate the need for a default gateway in the hosts. Virtual interfaces support subinterfaces.

What is the significant difference between a hub and a Layer 2 LAN switch? A hub forwards frames, and a switch forwards only packets. Each port of a hub is a collision domain, and each port of a switch is a broadcast domain. A hub divides collision domains, and a switch divides broadcast domains. A hub extends a collision domain, and a switch divides collision domains.

Which four steps are needed to configure a voice VLAN on a switch port? (Choose four). Ensure that voice traffic is trusted and tagged with a CoS priority value. Assign the voice VLAN to the switch port. Activate spanning-tree PortFast on the interface. Configure the interface as an IEEE 802.1Q trunk. Assign a data VLAN to the switch port. Configure the switch port interface with subinterfaces. Configure the switch port in access mode. Add a voice VLAN.

Assign the voice VLAN to the switch port. Ensure that voice traffic is trusted and tagged with a CoS priority value. Configure the switch port in access mode. Add a voice VLAN.

Which characteristic describes cut-through switching? Error-free fragments are forwarded, so switching occurs with lower latency. Buffering is used to support different Ethernet speeds. Frames are forwarded without any error checking. Only outgoing frames are checked for errors.

Frames are forwarded without any error checking.

Refer to the exhibit. A network administrator is configuring RT1 for inter-VLAN routing. The switch is configured correctly and is functional. Host1, Host2, and Host3 cannot communicate with each other. Based on the router configuration, what is causing the problem? IP addresses on the subinterfaces are incorrectly matched to the VLANs. Routers do not support 802.1Q encapsulation on subinterfaces. Interface Fa0/0 is missing IP address configuration information. Each subinterface of Fa0/0 needs separate no shutdown commands.

IP addresses on the subinterfaces are incorrectly matched to the VLANs.

Refer to the exhibit. PC1 is unable to communicate with server 1. The network administrator issues the show interfaces trunk command to begin troubleshooting. What conclusion can be made based on the output of this command? The encapsulation on interface G0/1 is incorrect. The DTP mode is incorrectly set to dynamic auto on interface G0/1. VLAN 20 has not been created. Interface G0/2 is not configured as a trunk.

Interface G0/2 is not configured as a trunk.

A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# ip address 172.18.33.88 255.255.255.0 command? It updates the MAC address table for the associated port. It activates a virtual or physical switch interface. It applies an IPv6 address to the virtual interface. It applies an IPv4 address to the virtual interface. It permits an IPv6 address to be configured on a switch physical interface.

It applies an IPv4 address to the virtual interface.

A network administrator is configuring inter-VLAN routing on a network. For now, only one VLAN is being used, but more will be added soon. What is the missing parameter that is shown as the highlighted question mark in the graphic? It identifies the native VLAN number. It identifies the number of hosts that are allowed on the interface. It identifies the type of encapsulation that is used. It identifies the VLAN number. It identifies the subinterface.

It identifies the VLAN number.

What is a characteristic of a routed port on a Layer 3 switch? It is not assigned to a VLAN. It supports trunking. It cannot have an IP address assigned to it. It is commonly used as a WAN link.

It is not assigned to a VLAN.

The network administrator wants to configure Switch1 to allow SSH connections and prohibit Telnet connections. How should the network administrator change the displayed configuration to satisfy the requirement? Reconfigure the RSA key. Use SSH version 1. Modify the transport input command. Configure SSH on a different line. Navigation Bar

Modify the transport input command

A network contains multiple VLANs spanning multiple switches. What happens when a device in VLAN 20 sends a broadcast Ethernet frame? Only devices that are connected to the local switch see the frame. Only devices in VLAN 20 see the frame. All devices in all VLANs see the frame. Devices in VLAN 20 and the management VLAN see the frame.

Only devices in VLAN 20 see the frame.

Refer to the exhibit. What is the cause of the error that is displayed in the configuration of inter-VLAN routing on router CiscoVille? The IP address on CiscoVille is incorrect. The encapsulation dot1Q 20 command has not been configured.​ The gig0/0 interface does not support inter-VLAN routing. The no shutdown command has not been configured.

The encapsulation dot1Q 20 command has not been configured.​

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? Gi0/0 is not configured as a trunk port. The no shutdown command is not entered on subinterfaces. The encapsulation dot1Q 5 command contains the wrong VLAN. There is no IP address configured on the interface Gi0/0. The command interface GigabitEthernet0/0.5 was entered incorrectly. Navigation Bar

The encapsulation dot1Q 5 command contains the wrong VLAN.

Which two characteristics describe the native VLAN? (Choose two.) The native VLAN provides a common identifier to both ends of a trunk. Designed to carry traffic that is generated by users, this type of VLAN is also known as the default VLAN. High priority traffic, such as voice traffic, uses the native VLAN. The native VLAN traffic will be untagged across the trunk link. This VLAN is necessary for remote management of a switch

The native VLAN provides a common identifier to both ends of a trunk. The native VLAN traffic will be untagged across the trunk link.

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.

There is an incorrect IP address configured on GigabitEthernet 0/0.30.

Refer to the exhibit. A network administrator is reviewing port and VLAN assignments on switch S2 and notices that interfaces Gi0/1 and Gi0/2 are not included in the output. Why would the interfaces be missing from the output? They are administratively shut down. There is no media connected to the interfaces. There is a native VLAN mismatch between the switches. They are configured as trunk interfaces.

They are configured as trunk interfaces.

How do switch buffers affect network performance? They provide error checking on the data received. They store frames received, thus preventing premature frame discarding when network congestion occurs. They provide extra memory for a particular port if autonegotiation of speed or duplex fails. They hold data temporarily when a collision occurs until normal data transmission resumes.
