1. Which of the following are true regarding VLANs?A. You must have at least two VLANs defined in every Cisco switched network.B. All VLANs are configured at the fastest switch and, by default, propagate this information to all other switches.C. You should not have more than 10 switches in the same VTP domain.D. VTP is used to send VLAN information to switches in a configured VTP domain.2. How does inter-VLAN communication take place?A. Using a layer 2 switchB. Using a routerC. Using a hubD. Using a repeater3. Which two statements about frame tagging are true?A. A filtering table is loaded into each switch.B. Frame tagging assigns a user-defined ID to each frame.C. A unique identifier is placed in the header of each frame as it is forwarded between switches.D. It is used by switches to control broadcasts.4. How are dynamic VLANs configured?A. StaticallyB. By an administratorC. Via a DHCP serverD. Via a VLAN Management Policy Server5. Which of the following protocols are used to configure trunking on a switch? (Choosetwo options.)A. VLAN Trunk ProtocolB. VLANC. TrunkD. ISL6. What is Ciscos proprietary frame-tagging method?A. 802.1QB. 802.3C. ISLD. VTP7. Which switching technology reduces the size of a broadcast domain?A. ISLB. 802.1QC. VLANsD. STP8. What VTP allows you to change VLAN information on the switch?A. ClientB. STPC. ServerD. Transparent9. What is the main purpose of creating VLANs?A. Break up collision domains at layer 2B. Break up collision domains at layer 3C. Break up broadcast domains at layer 2D. Break up broadcast domains at layer 310. Which of the following is true regarding VTP?A. All switches are VTP servers by default.B. All switches are VTP transparent by default.C. VTP is on by default with a domain name of Cisco on all Cisco switches.D. All switches are VTP clients by default.11. Which of the following is true regarding trunked links?A. They are configured by default on all switch ports.B. They only work with a type of Ethernet networknot with Token Ring, FDDI, or ATM.C. You can set trunk links on any 10-, 100-, and 1000Mbps ports.D. You must clear the unwanted VLANs by hand.12. Which of the following commands sets a trunk port on a 2950 switch?A. trunk onB. trunk allC. switchport trunk onD. switchport mode trunk13. Which of the following is an IEEE standard for frame tagging?A. ISLB. 802.3ZC. 802.1QD. 802.3U14. You connect a host to a switch port, but the new host cannot log into the server that is pluggedinto the same switch. What could the problem be? (Choose the most likely answer.)A. The router is not configured for the new host.B. The VTP configuration on the switch is not updated for the new host.C. The host has an invalid MAC address.D. The switch port the host is connected to is not configured to the correct VLANmembership.15. When is frame tagging used?A. When VLANs are traversing an access linkB. When VLANs are traversing a trunked linkC. When ISL is used on an access linkD. When 802.1Q is used on an access link16. When talking about frame tagging with VLAN ID, which of the following would be used to describe this?A. VTP with multiple switches and VLANsB. VLAN color and placementC. Identifying VLAN memberships over trunked linksD. Connecting an access port to a switch a router with ISL17. Which of the following provide inter-switch VLAN communication? (Choose two.)A. ISLB. VTPC. 802.1QD. 802.3Z18. You have two switches connected with a trunked link running two VLANs. VLAN 1 is assigned to ports 1 through 3 of each switch and VLAN 2 has been assigned to ports 8 through 12 of each switch. HostA and HostB are in VLAN 1. HostG and HostH are in VLAN 2. There is no inter-VLAN routing. What should you do to verify proper VLAN and trunk operations? (Choose three.)A. Verify that HostA can ping HostB.B. Verify that HostA can ping HostG.C. Verify that HostG can ping HostH.D. Verify that HostG cannot ping HostA.E. Verify that HostA cannot ping HostB.19. You need to add a new VLAN named ROUTERSIM to your switched network.
