Users are complaining of delays when using the network What would you do?
There are lot of concerns that cause network delays, The Administrator / Network Enginrer must check the following simple tasks before he / she proceed.  get the user(s) to demonstrate the problem.  determine how many other users are affected.  ensure desktop hardware and configuration is OK.  trace all connections (they may be on another subnet).  commence some monitoring or diagnostics.  determine problem (if there is one).  check for the virus / spyware activity.  If everything seems OK, then try to restart the router / switch, same time try to restart the system.
What does network monitoring mean?
Network monitoring is generally referred to as the use of one system that monitors all activities on the network. If a problem is detected within the network, like a failing component of the network, the network administrator is then notified so that they may deal with and correct the problem very quickly or as quick as possible.
What are the benefits of using the DHCP?
DHCP is Dynamic Host Configuration Protocol. In a networked environment it is a method to assign an 'address' to a computer when it boots up. Benefit: A system administrator need not worry about computers being able to access networked resources. Disadvantages: (I'm still looking for it)
Which utility can be used to automatically diagnose a problem with a network connection?
window network diagnostics
Identify any problems that are associated with networked computers?
Regardless of the size or number of employees, every company experiences problems at some time or other. Anticipating the most common problems ahead of time and working to avoid them is the best way to reduce calls and ensure a smooth daily experience. Quite often, when that phone does ring, the problems tend to be the same, since there are some very common problems that can present themselves in any environment that utilizes a networked system. One problem that may arise is the issue of a duplicate IP address. This is, quite simply, the address that the network uses to identify a specific computer. Every PC - and laptop - possesses a unique IP address, but sometimes two will receive the same one as the result of an error. When this happens, communications problems arise and the Systems Administrator or Network Engineer will need to change the address on one of the computer terminals in order to fix the problem quickly and easily. Connectivity issues are among the most common problems that are brought to the doorstep of the systems department of a company. This can be caused by a number of things, including configuration changes or the malfunction of connectivity devices, such as in the case of a hub. The first thing to do, of course, is to check your physical connections. If something is disconnected, you'll need to reconnect and test it in order to make sure that the problem is resolved. If all physical connections look to be in place, check that the port on the hub to which the cabling is connected is on and working properly. There should be a green light on at the port site which indicates that the port is live and ready to connect. Similar can be done with switches and . If these look to be stable, then check the configuration of the equipment that's experiencing the problem. It could well be that it simply needs to be reconfigured to accommodate the type of equipment that's been attached to make the In the same spirit, there are sometimes simply problems with the physical cables that connect various types of computerized equipment. Sometimes these physical connections become broken, severed or simply short out. In the case of an electrical short, this can happen when the conductor comes into contact with an outside source that also serves as a conductor. This will reroute the signal and cause networking and/or other electrical problems. In order to correct these types of problems, check to see if the physical connections have been compromised. If so, these can easily be changed, or new wiring can be manufactured with the proper connections by the staff members of the systems department. If nothing appears to be physically disrupted, then cable testers can be utilized to test for other types of electrical and networking problems. These include connection problems, electrical shorts in the cabling, incorrect cable connections and the interference level, in the case of a signal disruption due to diverted conductor paths. Software problems can be the cause of networking problems, as well. When all of the physical possibilities have been eliminated, you'll need to look to the actual system to discover what the cause of the problem may be. A variety of configuration problems may be at the root of the situation, such as those of the WINS or DNS variety. Registry problems may also cause a networking issue, as well as a number of other software-related possibilities. Depending upon the cause of the problem, you'll need to either make configuration changes or, perhaps, reinstall a specific piece of the software that may have malfunctioned. If you should find that your connectivity is unusually slow, this may be a sign of excessive network collisions. This is sometimes the result of a network that's been poorly planned or mapped out, or of a user transferring an inordinate amount of information at one time, which floods the network. There are options for transferring data without putting undue pressure on the system, such as in the case of word processing documents that are bulky. These can be sent as zipped files, which will send the information without violating any of the data, yet relieves the network of the amount of pressure that it would have taken to transmit the data if it hadn't been zipped. A jabbering network card - a network card that's stuck in the transmit mode - can also cause excessive network collisions. You'll be able to recognize this because the transmission light will remain on continuously, which literally means that the network card is transmitting on a nonstop basis. This can be alleviated by replacing the necessary components and testing them to be sure that the problem has been eliminated. There's a way to combat any networking issue - it's just a matter of being prepared and knowing what the most common problems are, so that you'll have the necessary tools at hand to make whatever corrections are needed as smoothly and quickly as possible.
How does a network administrator use the osi model to isolate a network problem?
the network administrator uses the OSI model to troubleshoot network problem by verifying functionality of each layer, in many cases, troubleshooting the network problem requires the network administrator to isolate at what layer the network problem occurs. network administrators often describe networking problems by layer number, for example, a physical link problem is described as a layer 1 problem; a router problem is a layer 3.
Which problem is caused by redundant connections in a network?
Switch loops
What should the network administrator do to troubleshoot this problem?
check the hello and dead intervals between the routers

What an administrator should take the time to troubleshoot all network problems correctly by asking specific question designed to identify the problem?
scope
Which stage in the process of gathering network symptoms involves determining if the problem is more likely a hardware or software configuration problem?
You determine symptoms through observation and operation. You then diagnose where the problem occurs in the network, and determine whether the problem is excessive data (i.e. software) or component failure
If you install a new network interface card and the systems reboots continuously how to you correct the problem?
use the last known good configuration
What actions should the networks administrator takes if the networks fails?
In general the network admin should 1: determine the problem 2: fix the problem 3: restore the network. In mission critical situations where restoring the network is a priority, then the admin may want to reverse that order. In less mission critical networks it's likely that some time may be spent determining the problem, but if too much time has passed and the organization may be affected, the network should be restored. In a test network, or in situations where the network continues to fail, the netwrk administrator may have no choice but to track down the problem first. An exact answer to this question would be possible given more information - is the network itself down or is a key server down- for example.
Cannot communicate with primary dns server?
Check your network connections. That is usually a main problem of not communicating with either DNS or DHCP on a LAN.
A network administrator has been informed about a problem with the network printer What is the most reliable way to prevent print jobs from being added to the queue while the printer is being repaire?
IT Essentials 1... Stop the print spooler.
What is admin support?
Admin support refers to support from your network administrator, and usually comes up when referring to issues with file transfers/sharing, permissions, emails, or some other form of Internet or network problems. When you are told to get admin support, you are basically being told to talk to your 'network guy' about the problem. The network administrator can usually correct such issues, or at least explain why they exist. If you do not have a network admin to talk to, such as with a home network that you set up, then you are basically going to have to pay for some tech support, unless you have a geek friend that's available and willing to help. You might be able to do some online research to diagnose and hopefully correct the problem.
