With which type of policy, a router can manage the flow of data and voice traffic, giving priority to voice communications if the network experiences congestion?

QoS means that a router will manage the flow of data and voice traffic, giving priority to voice communications.

What is a fault tolerance?

A fault tolerant network is one that limits the number of affected devices during a failure. It is built to allow quick recovery when such a failure occurs. These networks depend on multiple paths between the source and destination of a message. If one path fails, the messages are instantly sent over a different link. Having multiple paths to a destination is known as redundancy.

What is a scalability?

A scalable network expands quickly to support new users and applications. It does this without degrading the performance of services that are being accessed by existing users.

Having multiple paths to a destination is known as redundancy. This is an example of which characteristic of network architecture?

Redundancy is an example a fault-tolerant network architecture.

What is a network security?

Activities designed to protect a network and its data.

What are the three primary requirements?

Confidentiality - Data confidentiality means that only the intended and authorized recipients can access and read data. Integrity - Data integrity assures users that the information has not been altered in transmission, from origin to destination. Availability - Data availability assures users of timely and reliable access to data services for authorized users.

Confidentiality, integrity, and availability are requirements of which of the four basic characteristics of network architecture?

Confidentiality, integrity, and availability are requirements of security.

What are the four basic characteristics that network architects must address to meet user expectations?

Fault Tolerance Scalability Quality of Service (QoS) Security

When designers follow accepted standards and protocols, which of the four basic characteristics of network architecture is achieved?

Scalability happens when designers follow accepted standards and protocols.

What is a quality of service?

Giving someone enough bandwidth to use an application. Therefore making the best of limited bandwidth
