The purpose and basic operation of the protocols in the OSI and TCP models and their associated protocols is to:
Standardize network communication and ensure interoperability between different systems.
Provide only physical connectivity between devices.
Encrypt all data transmitted over the network by default.
Limit network access to a single protocol.
The path between two hosts across a network is influenced by which of the following factors?
Routing algorithms, network topology, and link costs
Only the physical distance between hosts
The operating system of the hosts
The color of network cables
Select the appropriate media, cables, ports, and connectors to connect switches to other network devices and hosts.
Use Ethernet cables with RJ-45 connectors and appropriate switch ports.
Use HDMI cables with USB connectors and audio ports.
Use fiber optic cables with VGA connectors and serial ports.
Use coaxial cables with PS/2 connectors and parallel ports.
Which of the following lists the correct steps to perform, save, and verify initial switch configuration, including switched virtual interfaces (SVI) and default gateway?
Configure the switch, assign SVI, set default gateway, save configuration, verify settings.
Assign SVI, verify settings, configure switch, set default gateway, save configuration.
Set default gateway, configure switch, assign SVI, verify settings, save configuration.
Verify settings, configure switch, assign SVI, set default gateway, save configuration.

The color order of wires inside an Ethernet connector must follow T568A or T568B standards because:
It looks better
It keeps costs low
Which of the following is true about why network cables are twisted?

Exceeding UTP length limits
Using twisted pairs in proper order
Bending fiber cables too sharply
A default gateway on a switch allows the switch to communicate outside its own network.
True
False
A switched virtual interface (SVI) on a switch is mainly used to:
Give the switch an IP address for management
Provide a physical connection for end devices
Power devices over Ethernet
Increase the switch’s speed
A technician reads a label that says “Cat 6 – 23 AWG – 350 MHz.” What does the “Cat” in Cat 6 cable tell you?
