What are two characteristics of a scalable network choose two group of answer choices?
What are two characteristics of a scalable network? (Choose two.)
- easily overloaded with increased traffic.
- grows in size without impacting existing users.
- is not as reliable as a small network.
- suitable for modular devices that allow for expansion.
- offers limited number of applications.
What are the characteristics of scalability?
Scalability is a characteristic of an organization, system, model, or function that describes its capability to cope and perform well under an increased or expanding workload or scope.
What is a scalable network?
A scalable network is one that can grow with the company and still be able to serve company needs. It also includes IT network solutions such as hardware and applications, data security, and the increased demand that both hardware and software are likely to see with company growth.
What does scalability mean?
Scalability is the measure of a system’s ability to increase or decrease in performance and cost in response to changes in application and system processing demands. Enterprises that are growing rapidly should pay special attention to scalability when evaluating hardware and software.
How do you achieve network scalability?
How can I make my network scalable?
- Determine your current and projected network requirements. Here, being data-driven helps to optimize costs and enable efficient network performance scaling.
- Have one comprehensive network management tool.
- Lease networking hardware and software.
- Scale out instead of up.
What is scalability and how do you achieve scalability?
In short: Scalability means that an application or a system can handle greater loads by adapting. So now, if your load on your application is high, you have two options of doing Scalability to handle it: Horizontal Scalability. Vertical Scalability.
How do you achieve scalability in distributed systems?
We have two basic ways to achieve scalability, namely increasing system capacity, typically through replication, and performance optimization of system components.
What is network availability?
Network availability, also known as network uptime, is a measure of how well a computer network—whether a local area network (LAN) or a wide-area network (WAN)—can respond to the connectivity and performance demands placed on it.
What is network high availability?
What is high availability (HA)? In context of IT operations, the term High Availability refers to a system (a network, a server array or cluster, etc.) that is designed to avoid loss of service by reducing or managing failures and minimizing planned downtime.
What is network uptime?
Network uptime refers to the time when a network is up and running. In contrast, downtime is the time when a network is unavailable. The concept of “five-nines” — a network availability of 99.999% — has been an industry gold standard for many years.
What can affect network availability?
The performance of a network can be affected by various factors:
- the number of devices on the network.
- the bandwidth of the transmission medium.
- the type of network traffic.
- network latency.
- the number of transmission errors.
How can we improve network availability?
Take a look at our top five tips.
- Use Network and Device Monitoring Software.
- Implement a Change Control Programme.
- Use Automated Incident Response Solutions.
- Use the Cloud.
- Have a Rehearsed Plan.
What slows down a network?
Two of the most frequent causes of poor Internet performance are spyware and viruses. Spyware can slow your system by interfering with your browser and monopolizing your Internet connection. Spyware monitors your Internet use and keystrokes, which adds delays. Computer viruses can also cause poor Internet performance.
What is bandwidth availability?
Bandwidth availability plays an important role when using VoIP or WebRTC services. Your ISP can confirm what bandwidth you signed up for. ISPs generally refer to bandwidth as an “up to” value, as in “up to 50 Mbps” or “up to 150 Mbps”.
What is effective bandwidth?
The effective bandwidth is defined as the width of the radiation at half of its maximum throughput. The ideal wavelength selector has a high throughput of radiation and a narrow effective bandwidth.
What is a good bandwidth?
The FCC does recommend speeds less than 25 Mbps for many online activities, including streaming SD and HD video, gaming online and downloading music. However, these are minimum speed recommendations and do not account for connecting multiple devices or other factors that may slow your internet speeds.
What is the purpose of bandwidth?
Bandwidth describes the maximum data transfer rate of a network or Internet connection. It measures how much data can be sent over a specific connection in a given amount of time. For example, a gigabit Ethernet connection has a bandwidth of 1,000 Mbps (125 megabytes per second).
How do you explain bandwidth?
Bandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps).
What are the types of bandwidth?
Types of Bandwidth
- PUBLIC WIRELESS. Long Term Evolution (LTE) cellular service, also referred to as 4G, and satellite tend to be more expensive than terrestrial services offering similar bandwidth.
- PUBLIC BROADBAND.
- PRIVATE NETWORKS.
- SOFTWARE-DEFINED WIDE AREA NETWORKS (SD-WAN)
