Cisco

Most Cisco phones act as a two-port switch, with one port facing the network and the other port for attaching a desktop device like a PC.

Dialog Control is the main function of Session layer.

Session layer manages dialogs between two computers and it is responsible for communication or conversation.

There are three forms of dialog.

1. Simplex dialogs : one way transfers, for example.. computer to printer ( computer will send data to printer and printer will receive the data ).

2. Half-Duplex Dialogs - Two-way transfers, Each device must take their turn. Both cannot transfer at the same time. for example..walkies-talkie

3. Full-Duplex Dialogs - Two-way simultaneous data transfers. Each device has it's own channel. for example.. telephone.

Cisco Systems, Inc., one of the leading manufacturers of routers and switches, offers quite a few different certifications that certify that you are able to work with Cisco devices, and networks in general, at a certain level. These are often requirements for technical jobs in the networking industry.

Collisions can decrease network performance.

There are more than 3 protocols at the application layer. Three well-known protocols are:

HTTP - web page traffic

FTP - file transfer traffic

SMTP - email transfer

A. Traffic is classified based on quality of service requirements.

D. Digital movies are always assigned to the high-priority queue for processing.

In flash memory. This is the equivalent of what, in a PC, would be the hard disk. However, when the router or switch is turned on, a copy of the IOS file is loaded into RAM. This, too, is equivalent to a PC, which needs to load its programs into RAM.

MAC address

In cases where a connection is established, the sender, the receiver and the subnet conduct a negotiation about parameters to be used. Parameters like maximum size of the message, quality of service etc are considered. One side can make a proposal and the other can accept it, reject it or make a counter proposal.

The Cisco 7200 series routers supports a wide range of density, performance, and service requirements. They are highly flexible and can support fast Ethernet.

server

A network administrator is selecting a switch that will operate at the network core. Which three features should the switch support for optimum network performance and reliability? (Choose three.)

first is both of them are havn same A.D. ie 120 as well as same vector and both supports till 15 hope counts.

The answer is yes. If you need more information, please be more specific on what it is you're trying to do.

Yes. Generally you plug your internet connection into the router, then an ethernet wire from the router to the switch. More than likely, depending on what set-up you previously had, your going to have to change your tcp/ip settings. I could probably guess what set-up you have... but you'll have to be more specific before we can give more advice.

The IPv4 address is identical for all hosts in a broadcast domain.

The IPv4 addresse varies in length.

The IPv4 address is used to forward packets.

Since there is no option given, we will just provide three statement that can identify the role of intermediary devices. Its three roles on the network are: determination of data pathways, data signal retiming and retransmitting, and data flow management.

generally static routing protocol has the most trustworthy administrative distance .i.e; 1 and in dynamic routing protocols EIGRP has the best AD.

It's probably 26,000 - 27,000
