Explanation: Networks must be able to quickly grow to support new users and services, without impacting existing users and services. This ability to grow is known as scalability.
Besides, what are two functions of Nvram choose two?
(Choose two.) Explanation: NVRAM is permanent memory storage, so the startup configuration file is preserved even if the router loses power.
Similarly, why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask? Explanation: ANDing allows us to identify the network address from the IP address and the network mask.
Also question is, what is the purpose of having a converged network?
In a converged network, voice, video, and data travel over the same network, thus eliminating the need to create and maintain separate networks. This also reduces the costs associated with providing and maintaining the communication network infrastructure.
What is an advantage of network devices using open standard protocols?
An advantage of network devices implementing open standard protocols, such as from the TCP/IP suite, is that clients and servers running different operating systems can communicate with each other.
What are two examples of the cut through switching method?
What are two examples of the cut-through switching method? (Choose two.)- store-and-forward switching.
- fast-forward switching.
- CRC switching.
- fragment-free switching.
- QOS switching. Explanation: Store-and forward switching accepts the entire frame and performs error checking using CRC before forwarding the frame.
Which two characteristics are associated with UDP sessions choose two?
Which two characteristics are associated with UDP sessions? (Choose two.)- Destination devices receive traffic with minimal delay.
- Transmitted data segments are tracked.
- Destination devices reassemble messages and pass them to an application.
- Received data is unacknowledged.
- Unacknowledged data packets are retransmitted.
What are two functions that are provided by the network layer choose two?
What are two functions that are provided by the network layer? the network layer is primarily concerned with passing data from a source to a destination on another network. IP addresses supply unique identifiers for the source and destination. The network layer provides connectionless, best-effort delivery.What are two actions performed by a Cisco switch choose two?
What are two actions performed by a Cisco switch? (Choose two.)- building a routing table that is based on the first IP address in the frame header.
- using the source MAC addresses of frames to build and maintain a MAC address table.
- forwarding frames with unknown destination IP addresses to the default gateway.
What are three characteristics of multicast transmission choose three?
What are three characteristics of multicast transmission? (Choose three.)- The source address of a multicast transmission is in the range of 224.0.
- A single packet can be sent to a group of hosts.
- Multicast transmission can be used by routers to exchange routing information.
- The range of 224.0.
Which two statements correctly describe a router memory type and its contents?
Which two statements correctly describe a router memory type and its contents? RAM is volatile and stores the IP routing table. ROM is nonvolatile and contains basic diagnostic software.What is ccna1?
Internet Engineering I (CCNA1) CCNA Routing and Switching curriculum is a gateway to entry-leve networking jobs and IT Careers. The curriculum consists of 4, 70-hour courses: Introduction to Networks (Internet Engineering 1 (CCNA1)) Routing and Switching Essentials (Internet Engineering 2 (CCNA2)).How is SSH different from telnet?
SSH is a network protocol used to remotely access and manage a device. The key difference between Telnet and SSH is that SSH uses encryption, which means that all data transmitted over a network is secure from eavesdropping. SSH uses the public key encryption for such purposes.Why would you use a router instead of a switch?
The most basic explanation is that a switch is designed to connect computers within a network, while a router is designed to connect multiple networks together. In a home network, a single router is usually all that is required for connecting devices to the Internet.What is the characteristic of a converged network?
A converged network is capable of delivering voice, video, text, and graphics over the same communication channels. Explain: When one network is used for all types of communication such as voice, video, text, and graphics, the network is referred to as a converged network.What is an example of network convergence?
Converged networks are moving us into a new world of technology. Cell phones offer a great example of this convergence. Users have access to streaming, media, telecommunications, and video conferencing simultaneously.What are two characteristics of a scalable network?
What are two characteristics of a scalable network?- Reliable and available - A flexible network should provide QoS for different applications.
- Responsive - The internetwork must be capable of responding to latency issues common for Systems Network Architecture (SNA) traffic.
- Efficient - Large internetworks should maximize resource utilization, especially bandwidth.
What is meant by the term converged network?
Network convergence is the efficient coexistence of telephone, video and data communication within a single network. The use of multiple communication modes on a single network offers convenience and flexibility that are not possible with separate infrastructures.What is the most effective way to mitigate worm and virus attacks?
Installing the most recent security updates from the operating system vendor on all vulnerable systems is the most effective way to mitigate a worm and virus attacks.What is the difference between a switch and a hub?
a hub. A switch is used to connect various network segments. A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). A Hub connects multiple Ethernet devices together, making them act as a single segment.What are the challenges of a converged network?
Use of the Converged Plantwide Ethernet system can resolve many of these challenges.These features, which are viewed as best practices are:
- Industrial characteristics.
- Interconnectivity and interoperability.
- Real-time communication, determinism, and performance.
- Availability.
- Security.
- Manageability.
- Scalability.
