SWRE Unit 3

What is a benefit of smaller broadcast domains

• Increased network traffic
• More open to security breaches
• Reduction of unnessecary traffic
• More complicated set up and maintenance

Which VLAN is used for secure and or encrpted traffic?

• Default
• Data
• Native
• Mangement

Which type of VLAN is assigned to 802.1Q trunk ports to carry untagged traffic?

• Default
• Native
• Data
• Mangement

Which is true of VLAN 1? (Choose 3)

• All switch ports are assigned
• The native VLAN is VLAN 99 by default
• The Management VLAN is VLAN 1 by default
• VLAN 1 cannot be renamed or deleted

A network administrator is using the router-on-a-stick model to configure a switch and a router for inter-VLAN routing. What configuration should be made on the switch port that connects to the router?

• Configure it as a trunk port and allow only untagged traffic.
• Configure the port as an access port and a member of VLAN1.
• Configure the port as an 802.1q trunk port.
• Configure the port as a trunk port and assign it to VLAN1.

A network administrator has found a user sending a double-tagged 802.1Q frame to a switch. What is the best solution to prevent this type of attack?

• The native VLAN number used on any trunk should be one of the active data VLANs.
• The VLANs for user access ports should be different VLANs than any native VLANs used on trunk ports.
• Trunk ports should be configured with port security.
• Trunk ports should use the default VLAN as the native VLAN number.

What is the effect of entering the shutdown configuration command on a switch?

• It enables BPDU guard on a specific port.
• It disables an unused port.
• It enables portfast on a specific switch interface.
• It disables DTP on a non-trunking interface.

What is the second action in the boot sequence when a switch is powered on?

• load the default Cisco IOS software
• load boot loader software from ROM
• low-level CPU initialization
• load a power-on self-test program

A network administrator issues the show vlan brief command while troubleshooting a user support ticket. What output will be displayed?

• the VLAN assignment and membership for device MAC addresses
• the VLAN assignment and membership for all switch ports
• the VLAN assignment and trunking encapsulation
• the VLAN assignment and native VLAN

Which two statements are correct with respect to SVI inter-VLAN routing on a layer 3 switch? (Choose two.)

• Switching packets is faster with SVI.
• There is no need for a connection to a router.
• Virtual interfaces support subinterfaces.
• SVIs can be bundled into EtherChannels.
• SVIs eliminate the need for a default gateway in the hosts.
