Which two statements about the layered model of communication are true? (Choose two.)
Layering makes communication itself less complex.
Layer processes on a host logically communicate with the same layer processes on another host.
Layer processes on a host are independent and communicate with any of the other layers.
Layering facilitates troubleshooting by making it possible to diagnose and narrow a cause to specific layers.
Layering of functions is only theoretical and not implemented in real-world.
Layering makes communication itself less complex.
Layer processes on a host logically communicate with the same layer processes on another host.
Which statement is false regarding the encapsulation process?
Encapsulation is the process used by the sending device to remove one or more of the protocol headers.
Segment is the PDU of the transport layer.
The encapsulation process is performed from top to bottom layer.
Encapsulation increases the size of the PDU.
Encapsulation is the process used by the sending device to remove one or more of the protocol headers.
Which ISO OSI layer ensures that the application layer of the receiving system will be able to read the information that the application layer of another system has sent?
presentation layer.
Which option is available to a network engineer to interact with a network device?
A network engineer communicates directly with the device operating system using machine programming languages.
A shell program exposes operating system services and can be accessed via CLI or GUI.
A hardware input device, such as mouse, can be used to directly interact with the device.
The operating system can only communicate with the user through light indicators present on the outside of the hardware.
A shell program exposes operating system services and can be accessed via CLI or GUI.

What is the expected result of the show running-config | exclude ! command executed on the Cisco IOS device?
CLI will display the negated versions of the commands in the running configuration file.
CLI will display the running configuration file but without any lines containing “!” in them
CLI will display only the lines copied from the external source.
CLI will display only the lines different to the lines in the startup-config file.
CLI will display the running configuration file but without any lines containing “!” in them.

batch applications
real-time applications
interactive applications
human-to-human applications
interactive applications.
How does the Privileged EXEC Mode restrict the access to the configuration CLI commands?
The Privileged EXEC Mode provides access security by adding an additional password when trying to reach the configuration modes.
By default, the Privileged EXEC Mode asks users to enter passwords for entering the Global Configuration Mode.
Access to the Privileged EXEC Mode can be password protected to allow only authorized users to execute the privileged set of commands
Commands entered in the Privileged EXEC Mode intentionally show false device information for unauthorized users.
Access to the Privileged EXEC Mode can be password protected to allow only authorized users to execute the privileged set of commands.
What is the function of a WLAN controller?

automatically handle the configuration of wireless access point
allow wireless devices to connect to a wired network
connect networks and intelligently choose the best paths between networks
automatically handle the configuration of wireless access point.
