the distance the media can successfully carry a signal; the environment where the media is to be installed

A data center has recently updated a physical server to host multiple operating systems on a single CPU. The data center can now provide each customer with a separate web server without having to allocate an actual discrete server for each customer. What is the networking trend that is being implemented by the data center in this situation?

virtualization

wireless LAN

Which two statements correctly define types of network infrastructure? (Choose two.)

A WLAN is designed to wirelessly interconnect users and end points in a small geographical area. A SAN is designed to support data storage, retrieval, and replication.

Refer to the exhibit. Which set of devices contains only intermediary devices?

A, B, D, G

Which statement describes a characteristic of cloud computing?

Applications can be accessed over the Internet through a subscription.

Fill in the blank. An_________ is a private connection of LANs and WANs that belongs to an organization, and is designed to be accessible only by the members and employees of the organization, or others with authorization.

Intranet

For which three reasons was a packet-switched connectionless data communications technology used when developing the Internet? (Choose three.)

It can rapidly adapt to the failure of network devices and communication links. Data packets can travel through the network using multiple different paths. Network devices dynamically decide on the best available path to forward each packet.

Which tool provides real-time video and audio communication over the Internet so that businesses can conduct corporate meetings with participants from several remote locations?

TelePresence

Which statement describes a network that supports QoS?

The network provides predictable levels of service to different types of traffic.

Which statement describes a network that supports QoS?

The network provides predictable levels of service to different types of traffic. QoS means that the network can deliver services in a predictable, measurable, and, if necessary, guaranteed manner. QoS uses classification and queuing to manage the delivery of data, minimizing delay and packet loss.

What are two functions of intermediary devices on a network? (Choose two.)

They direct data along alternate pathways when there is a link failure. They filter the flow of data, based on security settings.

Which two statements about the relationship between LANs and WANs are true? (Choose two.)

WANs connect LANs at slower speed bandwidth than LANs connect their internal end devices. WANs are typically operated through multiple ISPs, but LANs are typically operated by single organizations or individuals.
