CCNA 200-301 EXAM 2025/2026
QUESTIONS AND ANSWERS 100% PASS
What is the primary purpose of a VLAN? - ANS To create a broadcast domain; enable
segmentation or isolation of broadcast traffic
Unassigned Cisco switch ports remain in which VLAN? - ANS VLAN 1
Do VLANs prevent broadcast storms? - ANS No, they minimize the size and effect of the
broadcast storm on neighbor switches and hosts
What are four advantages to using VLANs? - ANS 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? - ANS FFFF.FFFF.FFFF
What is the Layer 3 Broadcast Destination Address? - ANS 255.255.255.255

,What is VLAN 1 used for and can it be deleted? - ANS Management Traffic; it cannot be
deleted
What is the normal VLAN range? - ANS VLAN 2 - 1001
What is the extended VLAN range? - ANS VLAN 1006 - 4094
What VLANs are auto-created and cannot be deleted? - ANS VLAN 1, 1002 - 1005
What VLANs cannot be pruned from a trunk? - ANS VLAN 1006 - 4094
How many VLANs can be assigned to a switch access port? - ANS 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? -
ANS interface <interface#/#>
switchport mode access
switchport access vlan #
switchport voice vlan #
Where is the switch VLAN configuration stored? - ANS vlan.dat file
What commands would you use to globally create and name a VLAN? - ANS vlan #
name <name_of_vlan>
What is the default switch port mode? - ANS Access port
What will switch access ports do with am Ethernet frame it receives with an 802.1q tag? -
ANS It will discard the packet without learning the source MAC address

, What command would you use to configure a range of switch ports? - ANS interface range
gigabitethernet#/# - #
What command lists all VLANs configured on a switch? - ANS show vlan or show vlan brief
What command is used to display the switch ports assigned to a single VLAN? - ANS show
vlan id <vlan>
When are data messages forwarded to the default gateway? - ANS When the destination
subnet is on a different subnet than the endpoint
Does the Cisco default switch configuration have an IP default gateway? - ANS No
What command is used to create an IP default gateway? - ANS ip default-gateway
<ip_address>
What is the primary purpose of a switch? - ANS To make forwarding decisions based on
destination MAC address
List the network services provided by switches - ANS - Only read Ethernet frame headers and
forward traffic
- Create and maintain the MAC address table
- Create separate collision domains per switch port
- Create separate broadcast domains per VLAN
What method was used for detecting Ethernet collisions on older hubs and bridges? -
ANS Carrier Sense Multiple Access Collision Detection (CSMA/CD)
How many separate MAC address table does a switch create? - ANS A switch creates a
separate MAC address table for each configured VLAN
