CCNA 200-301 EXAM QUESTIONS AND ANSWERS
What is the primary purpose of a VLAN? - CORRECT ANSWER✅✅To create a broadcast domain; enable
segmentation or isolation of broadcast traffic
Unassigned Cisco switch ports remain in which VLAN? - CORRECT ANSWER✅✅VLAN 1
Do VLANs prevent broadcast storms? - CORRECT ANSWER✅✅No, they minimize the size and effect of
the broadcast storm on neighbor switches and hosts
What are four advantages to using VLANs? - CORRECT 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 commands would you use to globally create and name a VLAN? - CORRECT ANSWER✅✅vlan #
name <name_of_vlan>
What is the default switch port mode? - CORRECT ANSWER✅✅Access port
What will switch access ports do with am Ethernet frame it receives with an 802.1q tag? - CORRECT
ANSWER✅✅It will discard the packet without learning the source MAC address
What command would you use to configure a range of switch ports? - CORRECT ANSWER✅✅interface

brief
What command is used to display the switch ports assigned to a single VLAN? - CORRECT
ANSWER✅✅show vlan id <vlan>
, When are data messages forwarded to the default gateway? - CORRECT ANSWER✅✅When the
destination subnet is on a different subnet than the endpoint
Does the Cisco default switch configuration have an IP default gateway? - CORRECT ANSWER✅✅No
What command is used to create an IP default gateway? - CORRECT ANSWER✅✅ip default-gateway
<ip_address>
What is the primary purpose of a switch? - CORRECT ANSWER✅✅To make forwarding decisions based
on destination MAC address
List the network services provided by switches - CORRECT ANSWER✅✅- 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? - CORRECT
ANSWER✅✅Carrier Sense Multiple Access Collision Detection (CSMA/CD)
How many separate MAC address table does a switch create? - CORRECT ANSWER✅✅A switch creates
a separate MAC address table for each configured VLAN
What command lists the contents of the MAC address table for a switch? - CORRECT ANSWER✅✅show
mac address-table
When does a switch begin MAC address learning? - CORRECT ANSWER✅✅When a switch is first started
and connected hosts start sending frames? Also triggered when the aging time expires for an address
What is the default time that a switch removes MAC address table entries? - CORRECT ANSWER✅✅300
seconds
