Virtual Local Area Networks (VLANS) enable you to configure one or more switch ports into separate broadcast domains.

Based on the illustration above, choose the correct statement among the choices below:

T-carriers and SONET are the typical types of WAN digital technology.

It is a device that allows a computer to communicate over lines that uses analog signals.

Frames have the IP address and an error code added and are processed by the network interface.

Select the choices below that identify the device in the diagram's middle (pointed by an arrow). This device extends the distance a network can cover.

Hub allows only one computer to successfully transmit data at a time.

Network switches use auto-negotiate mode to determine the link speed and duplex mode.

What is a Wide Area Network (WAN)?

The following are WAN’s four most common connection methods except:

A network hardware device that cleans the network signal by filtering out electrical noise.

It is an OSI Model layer that provides the best path selection and IP addressing.

It enables several communication streams to travel simultaneously over the same cable segment.

It is a networked collection of LANs tied together by devices such as routers:

The following are examples of SaaS (Software as a Service) except:

The following are the categories of WAN equipment, select all that applies (multiple answers)

It is an OSI Model layer that defines how computers access the media.

It is an OSI Model layer that handles data formatting and translation.

A channel service unit/data service unit (CSU/DSU) performs a function similar to a modem, except all signals are analog.

A T-carrier line uses a signaling method called (TDM), which allocates a time slot for each channel. TDM stands for:

The following are categories of cloud computing except:

It is an OSI Model layer that provides access to network resources.

Cloud computing is a networking model in which data, applications, and processing power

are managed by clients on the Internet.

“ If a customer needs another 1000 GB of storage space, they can pay for the space without worrying about how that space is actually provided”, this is a concern addressed by Platform as a Service (PaaS).

The following are criteria to be considered in selecting the appropriate type of WAN connection method, select all that applies. (multiple answers)

It is an OSI Model layer that manages ongoing conversations between two computers

Other Application-layer protocols includes the following: select all that applies (multiple answers)

A channel service unit/data service unit (CSU/DSU) is a device that creates a analog connection between a LAN device (router) and the WAN link from the service provider.

A leased line provides a dedicated point-to-point connection from the customer’s LAN through the provider’s network and the destination network.

It is a series of binary 1s and 0s represented by some type of signal that has two possible states (0v or 5v).

Some tasks performed by Network Layer includes providing a physical (MAC) address for the network interface, verifying that incoming frames have the correct destination MAC address, receiving packets from the Internetwork layer and encapsulating them to create frames, and transmitting and receiving bit signals.

The following are better WAN technologies, except:

The following are examples of PaaS (Plastform As a Service) except:

It is the main protocol suite used in networks.

Which of the following is NOT a characteristic of WANs?

The Internetwork layer is responsible of main tasks, select all that applies: (multiple answers)

It is an OSI Model layer that breaks long data streams into smaller chunks called segments.

A server is the computer or network software that request network data.

Rapid Spanning Tree Protocol (RSTP) is an enhancement to Spanning Tree Protocol that provides faster

convergence when the topology changes.

It is a port used to connect two hubs together or to connect a hub to a switch.

Packets have the source and destination MAC address added and are processed by the network protocol.

Packets and frames are the units of data handled by different network components

A network hardware that lenghtens computer physical connection from one another

A type of network that use the services of third-party communication providers to carry network traffic from one location to another

Packets have the source and destination MAC address added and are processed by the network protocol.

In the illustration above, what common device was used to connect the network?

In the illustration above, what network device was used to connect the two Local Area Networks?

Frames have the IP address and an error code added and are processed by the network interface.

A switching loop occurs when switches are connected in such a way that it’s possible for frames to be forwarded endlessly from switch to switch in an finite loop.

An access Control List (ACL) is a set of rules configured on a switch interface to specify which addresses and protocols can pass through an interface and to which destinations.

Some advanced NIC features to consider include RAM buffering, onboard co-processors,

automatic link aggregation, and multiple ports for fault tolerance.

A switch reads data in the message, determines which port the destination device is connected to, and forwards the message to only that port.

The network engineer intends to enforce tighter security on network end users. On what network layer must he work on ?

Packets and frames are the units of data handled by different network components.

Organize these options into the right categoriesA type of computer network that use WAN technolologies to interconnect LANs in a specific geographic region.

A network repeater device maintains the strength of communication in longer distances of the cabled computer connection.

Multilayer switches can perform some of the same tasks as routers and offer a substantial

performance advantage.

Cut-through switching is the slowest method in which the switch reads only enough of the incoming frame to determine the frame’s source and destination addresses.

A multiport repeater with several ports to connect cables is commonly called:

A network hardware device that cleans the network signal by filtering out electrical noise.

It is a port used to connect two hubs together or to connect a hub to a switch.

Advanced features, such as VLANs, STP, multicast support, and port security are found on

smart routers.
