CCNA 200-301 Study Guide | 100% Correct |
Verified | 2024 Version
What is the primary purpose of a VLAN? - ✔✔To create a broadcast domain; enable segmentation or
isolation of broadcast traffic
Unassigned Cisco switch ports remain in which VLAN? - ✔✔VLAN 1
Do VLANs prevent broadcast storms? - ✔✔No, they minimize the size and effect of the broadcast storm
on neighbor switches and hosts
What are four advantages to using VLANs? - ✔✔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? - ✔✔FFFF.FFFF.FFFF
What is the Layer 3 Broadcast Destination Address? - ✔✔255.255.255.255
What is VLAN 1 used for and can it be deleted? - ✔✔Management Traffic; it cannot be deleted
What is the normal VLAN range? - ✔✔VLAN 2 - 1001
What is the extended VLAN range? - ✔✔VLAN 1006 - 4094
What VLANs are auto-created and cannot be deleted? - ✔✔VLAN 1, 1002 - 1005
,What VLANs cannot be pruned from a trunk? - ✔✔VLAN 1006 - 4094
How many VLANs can be assigned to a switch access port? - ✔✔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? - ✔✔interface
<interface#/#>
switchport mode access
switchport access vlan #
switchport voice vlan #
Where is the switch VLAN configuration stored? - ✔✔vlan.dat file
What commands would you use to globally create and name a VLAN? - ✔✔vlan #
name <name_of_vlan>
What is the default switch port mode? - ✔✔Access port
What will switch access ports do with am Ethernet frame it receives with an 802.1q tag? - ✔✔It will
discard the packet without learning the source MAC address
What command would you use to configure a range of switch ports? - ✔✔interface range
gigabitethernet#/# - #
What command lists all VLANs configured on a switch? - ✔✔show vlan or show vlan brief
What command is used to display the switch ports assigned to a single VLAN? - ✔✔show vlan id <vlan>
, When are data messages forwarded to the default gateway? - ✔✔When the destination subnet is on a
different subnet than the endpoint
Does the Cisco default switch configuration have an IP default gateway? - ✔✔No
What command is used to create an IP default gateway? - ✔✔ip default-gateway <ip_address>
What is the primary purpose of a switch? - ✔✔To make forwarding decisions based on destination MAC
address
List the network services provided by switches - ✔✔- 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? - ✔✔Carrier Sense
Multiple Access Collision Detection (CSMA/CD)
How many separate MAC address table does a switch create? - ✔✔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? - ✔✔show mac address-table
When does a switch begin MAC address learning? - ✔✔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? - ✔✔300 seconds
How do you disable MAC address table aging? - ✔✔Configure the MAC aging timer to zero
