Bandwidth Management

A virtual network feature that configures the amount of bandwidth used by virtual network adapters.

Online Collaboration

Individuals want to connect to the network, not only for access to data applications, but also to collaborate with one another.

Traffic Classification and Marking:

QoS starts with classifying different types of network traffic based on their characteristics or requirements. Network devices can mark packets with specific values (such as Differentiated Services Code Point or DSCP) to indicate their priority or class.

Quality of Service (QoS)

Policies that control how much bandwidth a protocol, PC, user, VLAN, or IP address may use.

Cloud Types

Public clouds, Private clouds, Hybrid clouds, and Community clouds

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

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

Scalability

Which feature is a good conferencing tool to use with others who are located elsewhere in your city, or even in another country?

video communication

As networks evolve

we have learned that there are four basic characteristics that network architects must address to meet user expectations: Fault Tolerance Scalability Quality of Service (QoS) Security

Recent Trends

As new technologies and end-user devices come to market, businesses and consumers must continue to adjust to this ever-changing environment.

Which feature describes using personal tools to access information and communicate across a business or campus network?

BOYD

Video - Cisco Webex for Huddles

Cisco Webex is incorporated into everyday life and business.

Which feature contains public, private, custom, and Hybrid options?

Cloud Computing

Congestion Management and Avoidance:

Congestion occurs when network resources become overwhelmed with traffic, resulting in performance degradation

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

Fault Tolerance

Scalability

How well a system can scale up, or adapt to the increased demands of growth

QoS Policies and Configuration:

Network administrators define QoS policies based on their organization's requirements and network characteristics.

Queuing and Scheduling

Network devices use queues to store and manage packets before transmitting them.

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

Security

Network Architecture

The design of a computer network; includes both physical and logical design.

QoS policy in place

The focus of QoS is to prioritize time-sensitive traffic. The type of traffic, not the content of the traffic, is what is important

Video Communications

Video is becoming a critical requirement for effective collaboration as organizations extend across geographic and cultural boundaries.

Which feature uses the same cellular technology as a smartphone?

Wireless Broadband

cloud computing architecture

allows employees and customers to access organizational data and applications located in the cloud

Bring Your Own Device (BYOD)

allows employees to use their personal mobile devices and computers to access enterprise data and applications

Fault Tolerance

the ability for a system to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service
