Block 3, Unit 1 - LAN Technologies + Unit 2 - VLAN Fundamentals

Lets pass this test , straight from Kahoot

What is a logical grouping of network devices into a single broadcast domain or flat network?

VLAN

Devices in different physical locations can be on the same VLAN

TRUE

By default all switch ports are a member of what VLAN?

VLAN 1

Define a trunk.

Connection between network devices that carries more that one VLAN

When an Ethernet frame crosses a trunk, what is applied?

VLAN tag

When a tagged VLAN frame arrives at an access port, the tag is _______.

Removed

What common trunking method is an open standard for trunks?

802.1q

What is the management VLAN used for?

Telnet, SNMP, and Syslog

802.1q encapsulation works with what model switches.

All models

What number should you not give to the management VLAN?

1

What are switches used for?

They are used to physically connect devices in a network

Switches build and maintain what kind of table?

Media Access Control (MAC) address table

What do switches break up?

Collision Domain

What switch component allows for the configuring of a “blank switch”

Console port

Each port on a switch is a separate collision domain?

True

What interfaces are devices such as computers and printers connect to?

Network Interfaces

Where is a switch OS saved?

Flash Memory

Where are diagnostic and boot up routines stored?

ROM

What memory location holds the “running-configuration” file?

RAM

What loads the startup configuration into RAM?

NVRAM

What are the functions of a switch?

• Address Learning

• Forward Filter Decision

• Loop Avoidance

How does a switch learn the addresses of the computers attached to it?

When the attached device sends the first frame

What switching function involves forwarding a frame to the port identified with a MAC address?

Forward Filter Decision

What occurs when a switch is overwhelmed by the continuous stream of traffic due to devices rebroadcasting?

Broadcast storm

Multiple copies of the same data from different LAN segments.

Multiple frame copies

Which switching method stores the entire frame in memory and checks frame for errors?

Store-and-forward

What switching method reduces latency but can forward bad frames?

Cut-through

Why does Fragment-Free Switching only check the first 64 bytes?

This is where fragmentation is most likely

What happens when two systems transmit at the same time>?

Collision

There is one best switching technique?

False
