COMPLETE QUESTIONS AND CORRECT ANSWERS |ALREADY
GRADED A+||BRAND NEW VERSION!
What is Cut-Through Switching? - ANSWER-It is a technique that optimizes
performance by examing only the first 6 bytes (destination MAC address) of an
Ethernet frame before making a forwarding decision. The switch does a MAC
address table lookup for the destination MAC address and forwards the frame.
What is the advantage of Cut-Through Switching? - ANSWER-The forwarding
decision is made before all of the frame arrives and thereby minimizes latency
What is Store-and-Forward Switching? - ANSWER-Traditional switching where the
frame is not forwarded until all of the frame has arrived. The switch copies the
frame to memory before examining the destination MAC address and forwarding
the frame.
What is CEF? - ANSWER-Cisco Express Forwarding: Layer 3 switching technique
that creates FIB and adjacency tables for optimized forwarding. It is only available
on routers and switch platforms with routing enabled and the required hardware
What is an FIB? - ANSWER-Forwarding Information Base: Used by CEF to mae IP
destination prefix-based switching decisions. Conceptually similar to a routing
table or information base. It maintains a mirror image of the forwarding
information contained in the IP routing table.

Which devices can perform frame rewrite? - ANSWER-Layer 3 switches and
Wireless LAN Controllers
What is the primary purpose of a VLAN? - ANSWER-To create a broadcast domain;
enable segmentation or isolation of broadcast traffic
Unassigned Cisco switch ports remain in which VLAN? - ANSWER-VLAN 1
Do VLANs prevent broadcast storms? - ANSWER-No, they minimize the size and
effect of the broadcast storm on neighbor switches and hosts
What are four advantages to using VLANs? - ANSWER-1. Enable access to network
services based on logical requirements
2. Network security is optimized with VLANs that enable managing and filtering
sensitive traffic from other network traffic
3. Bandwidth efficiency is accomplished through segmenting traffic into smaller
broadcast domains
4. Easier add/move/delete administration of endpoints on a network and
scalability for larger enterprise deployments
What is the Layer 2 Broadcast Destination Address? - ANSWER-FFFF.FFFF.FFFF
What is the Layer 3 Broadcast Destination Address? - ANSWER-255.255.255.255

What is the normal VLAN range? - ANSWER-VLAN 2 - 1001
What is the extended VLAN range? - ANSWER-VLAN 1006 - 4094
What VLANs are auto-created and cannot be deleted? - ANSWER-VLAN 1, 1002 -
1005
What VLANs cannot be pruned from a trunk? - ANSWER-VLAN 1006 - 4094
How many VLANs can be assigned to a switch access port? - ANSWER-Only one
VLAN unless you are connecting an IP phone
What commands would you use to setup a switch access port with an IP phone? -
ANSWER-interface <interface#/#>
switchport mode access
switchport access vlan #
switchport voice vlan #
Where is the switch VLAN configuration stored? - ANSWER-vlan.dat file
