Basic Network Quiz

In a properly configured 10Base2 (Thinnet Ethernet) network using RG-58A/U coaxial cable with 50-ohm terminators, only ONE terminator should be grounded - typically at the hub or central point. Grounding both terminators creates ground loops, which cause signal interference, noise, and potential network failures. The terminators are correctly 50 ohms (not 93), RG-58A/U is the right cable for 10Base2, and impedance mismatch would occur with wrong cable types.

SAP (Service Advertising Protocol) is used to advertise services on a network, not to calculate routing paths. RIP, OSPF, and EIGRP are all valid routing algorithms used to determine the shortest or best path.

The star-bus (or tree) topology is the most common in modern corporate networks, combining the centralized management of a star topology with the scalability of a bus backbone.

RG-62 coaxial cable is characterized by its 93-ohm impedance, which distinguishes it from other common coaxial cable types. RG-58 uses 50 ohms (standard for Ethernet), RG-59 uses 75 ohms (commonly used for video/CATV), and RJ45 is an 8-pin connector (not a cable type). The 93-ohm impedance of RG-62 made it suitable for specific applications like IBM 3270 terminals and ARCnet networks.

In Windows 2000 Professional, device drivers can be disabled through Device Manager (the GUI method) or via the Recovery Console (a command-line startup option). The Recovery Console provides administrative access to disable problematic drivers that prevent the system from booting normally. ERD (Emergency Repair Disk), RDISK (creates ERD), and Disk Management Console don't offer driver disable functionality.

The Presentation layer (Layer 6) of the OSI model is responsible for the translation, encryption, and compression of data, ensuring that the application layer can understand the information.

Smart Cards in Windows 2000 use the Extensible Authentication Protocol (EAP) as the RAS authentication protocol. EAP provides a framework that supports multiple authentication methods, including smart card-based authentication via certificate-based credentials. PAP is plain-text (insecure), CHAP and MS-CHAP are challenge-response protocols for passwords, while EAP is specifically designed to accommodate smart cards and other advanced authentication methods.

Token Ring architecture is recommended under high network utilization (70-80%) because of its deterministic token-passing access method, which eliminates collisions and provides predictable performance. Ethernet bus (CSMA/CD) performance degrades significantly under load due to collision handling and exponential backoff. FDDI and DLC are not suitable answers - FDDI uses token passing but wasn't listed as the recommended architecture in this context.

Remote Access Service (RAS) supports multiple network protocols to ensure compatibility with various network environments, including TCP/IP, NetBEUI, and IPX/SPX.

A standard Token Ring network has a maximum limit of 260 computers (or stations) according to IEEE 802.5 specifications. This limit is based on timing requirements for token rotation around the ring. Options like 512 and 1024 exceed this limit, while 2024 is far beyond the specification. The 260-station maximum is a fundamental architectural constraint of Token Ring LANs.
