Answers
1) Answer: a, b, c, d. According to Novell Education the seven major tasks that person performing network service and support undertakes are:
- Install hardware and software.
- Configure the network hardware and software.
- Upgrade hardware and software.
- Document problems and fixes.
- Diagnose network problems using diagnostic equipment.
- Repair problems on the network.
- Investigate complaints and problems that occur on the network.
2) Answer: d. ESD or Electrostatic Discharge occurs when 2 dissimilar objects come into contact and exchange electrons to standardize the charge between them. ESD or static electricity is a major source of damage and destruction of electronic components. To feel static electricity the charge must be approximately 3000 volts. To see ESD the charge must be at least 10,000 volts. If a person moves across a carpet, i.e. normal movements, an ESD charge of 1000 volts is generated and not noticed. A charge of as little as 20-30 volts can damage and destroy computer components. This small charge might not cause immediate failure. The damaged component will only be noticed after a period of time.
ESD is a major source of component damage in the computer industry. For that reason, most manufacturers and support people follow ESD prevention methods. These methods include using ESD wrist straps, ESD floor and table mats, transporting components in static-shielding bags and keeping humidity in a work area in the 70-90% range.
Properly controlling ESD reduces the number of service calls a support person would have to attend to. Intermittent and difficult to trace problems are reduced. The biggest advantage to controlling ESD is the customers have fewer problems. They are therefore more satisfied with the product sold and the service provided. Satisfied customers are customers who will purchase equipment or service again. With ESD controls less hardware is required to be on hand for immediate use. When ESD is controlled service and support people spin their wheels less with impossible to trace problems. 3) Answer: b. Novell's Internet Support Connection. Novell's Internet Support Connection (like the Support Connection on CD and CompuServe) provides access to the most up-to-date information and file updates. If you have a Web browser, then you automatically have access to Novell's free on-line technical resources.
So why do you need Novell's Internet Support Connection? First, it makes you look smart. The Internet gives you instantaneous access to a world of CNEs. And let's be honest, we're all in this together, so let's help each other out, right? Here are a few more things that the Novell Support Connection on the Internet has to offer:
- Answers to technical questions: All of your technical questions will be answered by veteran System Operators (SysOps) and other NetWare gurus. SysOps come in a variety of shapes and sizes, but they all share one common thread - they're smart and like to answer lots of questions. In the unlikely event that a Novell Support Connection SysOp cannot answer your question, he or she will redirect it to engineers at Novell's Technical Support group. This is the same group that answers Novell Hot Line support calls.
- Roundtable discussions: Get in touch with more than 125,000 NetWare users and CNEs throughout the world. It is organized into functional rooms (forums) to help you focus on specific questions. You can use these rooms to post questions, read through conversations, or discuss specific topics with other NetWare enthusiasts. The world is getting very small.
4) Answer: b. However you slice it, Thin Ethernet is a great design for beginners and small LANs. Be sure to follow these simple guidelines when installing or troubleshooting Thin Ethernet:
- The maximum length of the total LAN cannot exceed 3,035 feet (or 925 meters). You can have five individual trunks of up to 607 feet (or 185 meters) each. Three of the five trunks can support 30 devices each. This is called the 5-4-3 rule.
- You can have a maximum of five trunks connected by four repeaters. Only three of these trunks can be populated.
- Workstations must be at least 1.5 feet (or 0.5 meters) apart.
- Thin Ethernet uses 50-ohm RG-58 thin coaxial cabling and requires a 50-ohm terminator at each end of each trunk. One of the terminators must be grounded.
- The Signal Quality Error (SQE) test must be turned off if repeaters are used. This feature is present on some Thin Ethernet NICs.
5) Answer: b, d. Drive cabling provides the communications path between the drive controller and physical disk. Each end of the ribbon cable has a special connector - one for the controller and one for the drive. No one has quite figured out yet how to make these connectors foolproof. They all look alike and are very hard to match. Fortunately, some connectors are marked to prevent you from putting the cable in backward. Make sure the special notch on the plastic connector matches the notch on the port of the drive or controller. Missing pins on one side of the connection should match filled-in pin holes on the other.
Drive cabling is also simplified by the addition of a red or blue stripe. The stripe on the cable identifies pin number 1 on the connector. Pin 1 on the drive should be identified by a small number 1 or a black square. Don't reverse these pin settings because you can cause irreparable damage to the drive and controller. One of the easiest ways to remember the orientation is to place pin 1 next to the power plug - "pin 1 goes to power." But whatever you do, don't plug the data ribbon cable into the power plug. This mistake can do wonders for your data.
6) Answer: a, b, c. The WOS interface makes it possible for workstations to see the network. In this analogy, NIOS drivers are workstation rods and NWFS drivers are cones. Together they comprise an intellectual interface between your workstation and network services. NIOS.VXD allows Windows 95 workstations to access NetWare's built-in I/O subsystem. Similarly, NWFS.SYS acts as a redirector/file system driver for Windows NT clients. In summary, the Novell Client offers two interface solutions for Windows 95/NT workstations:
- NetWare I/O Subsystem (NIOS) -- Serves as an interface layer between Windows 95 workstations and the network.
- NetWare File System (NWFS) Driver -- Serves as an interface layer between Windows NT workstations and the network.
Let's take a closer look. The NetWare I/O Subsystem (NIOS) is the heart of Windows 95 network connectivity. NIOS is implemented as a virtual device driver called NIOS.VXD. Once loaded, this driver initiates a variety of other workstation-based .NLM files through Windows 95 Registry.
NIOS is the workstation equivalent of SERVER.EXE. It provides the loader software and module launcher that initiates client modules and NLMs. Unlike SERVER.EXE (which has its own built-in memory manager), NIOS works with an extended memory manager that is already loaded with Windows 95. Once NIOS has access to the memory manager, it can dynamically allocate and de-allocate client settings. This advantage allows me to implement client changes without having to reboot the workstation.
7) Answer: b. WinLogin is an integral part of Microsoft Windows NT that provides a GUI interface for login support. One interesting thing about WinLogin is that it's modular--some pieces of it are replaceable. One such piece is called the Graphical Identification and Authentication (GINA) module. If you can learn how to replace the GINA module, it will give you a tremendous amount of flexibility in implementing other authentication mechanisms at the Windows NT client.
So, why do you care? Because Novell has written its own GINA module called NWGINA.DLL. This new identification module performs all authentication and user interactions for Windows NT clients on a Novell network. This is important to understand because the Novell Client for Windows NT automatically replaces the native NT GINA (called MNGINA.DLL) with NWGINA during installation. This is how Novell clients maintain a greater degree of security than native Windows NT clients do.
8) Answer: b. The queue-based printing troubleshooting flowchart. This flowchart asks some basic questions to help you identify the problematic printing component. Here's how it works:
- Did printing ever work? If not, you can assume the problem is in the printing setup. If so, you should move on to Step 2.
- Printing quick fixes. Before you move on to the final big question, you should try a few quick fixes just in case the problem is trivial. If any of these work, great! If not, move on to the Decision.
- The Decision. Finally, you must determine when the problem occurred before, during, or after the print queue. If the problem occurred before the job entered the print queue, it's the workstation's fault. However, if it occurred after the job left the print queue, it can be either the print server or printer's fault. Finally, many problems actually occur inside the print queue.
Remember, once you've identified the component, you can narrow down the solution to a small list of troubleshooting tips.
9) Answer: a, b. The first thing you should do is determine if local printing works at all. To do so, simply attach a local printer directly to the workstation. Then print from the command line, using DOS, and from the local application. This will help you determine whether the problem is with the application or the printing hardware. Also, you'll want to determine whether printing is conflicting with other workstation components such as TSRs, NICs, or the network connectivity software.
If you suspect the application, determine if it's NetWare-aware or not. If it is a NetWare-aware application, make sure you've configured it for the correct print queue. Also, make sure that you've got the most current printer driver. Out-of-date printer drivers often cause unpredictable results. If the application is not NetWare-aware, check your CAPTURE settings and make sure that they're being read correctly. Use the CAPTURE /SH command to view your current settings.
CAPTURE /SHOW
10) Answer: b. Novell uses a specific naming convention for operating system patch files. This convention consists of three components:
- The operating system version (first three characters).
- Passed Test (PT) patches handle the first problems found and solved for a given NetWare version. Support Packs (SP) include all update patches for a given NetWare version. These updates are tested individually and as a suite.
- Revision number or letter (last character).
The following are sample operating system patches that follow this convention: 312PTD.EXE (NetWare 3.12), 410PT8.EXE (NetWare 4.10), and IWSP5B.EXE (intraNetWare). Incidentally, you should always load all patches in a given revision kit.
