To answer this question, you need to understand the different directory services used in networking.

Option A) Active Directory - This option is incorrect because Active Directory is a directory service provided by Microsoft for Windows-based networks. It is not specific to Netware.

Option B) Domain Name System (DNS) - This option is incorrect because DNS is a protocol used to translate domain names into IP addresses. It is not a directory service.

Option C) NDS - This option is correct. NDS stands for Novell Directory Services, which is the directory service used in Netware. It provides a centralized database for managing and accessing network resources.

Option D) NWLink - This option is incorrect because NWLink is a protocol used for network communication in Netware. It is not a directory service.

Option E) DNS - This option is incorrect for the same reason as Option B. DNS is not a directory service.

The correct answer is C) NDS. This option is correct because NDS is the directory service used in Netware.

To answer this question, you need to understand the different diagnostic tools used to troubleshoot network issues. Let's go through each option to understand why it is correct or incorrect:

Option A) Multimeter - This option is incorrect because a multimeter is a tool used to measure voltage, current, and resistance in electrical circuits. It is not specifically designed to diagnose network interface card (NIC) issues.

Option B) Protocol Analyzer - This option is correct because a protocol analyzer is a diagnostic tool that captures and analyzes network traffic. It can help identify issues with a malfunctioning network interface card by examining the packets being sent and received by the card.

Option C) Signal Detector - This option is incorrect because a signal detector is used to detect and locate wireless signals, such as Wi-Fi or cellular signals. It is not specifically designed to diagnose network interface card issues.

Option D) Null Network Unit - This option is incorrect because a null network unit is a device used to simulate network connections and test network equipment. It is not specifically designed to diagnose network interface card issues.

Option E) Port Sniffer - This option is incorrect because a port sniffer, also known as a packet sniffer, is a tool used to capture and analyze network traffic. While it can help identify network issues, it is not specifically designed to diagnose network interface card issues.

The correct answer is B) Protocol Analyzer. This option is correct because a protocol analyzer is a diagnostic tool that captures and analyzes network traffic, helping to identify issues with a malfunctioning network interface card.

To answer this question, you need to understand the different types of network technologies and their corresponding speeds.

Let's go through each option to understand why it is correct or incorrect:

Option A) ISDN - Integrated Services Digital Network (ISDN) is a set of communication standards that enables digital transmission of voice, video, and data over traditional telephone lines. The maximum speed supported by ISDN is 128 Kbps, which is lower than 1.5 Mbps. Therefore, Option A is incorrect.

Option B) DSL - Digital Subscriber Line (DSL) is a technology that provides high-speed internet access over traditional telephone lines. While DSL can support speeds higher than 1.5 Mbps, it can also support lower speeds depending on the specific DSL variant and the distance from the DSL provider's central office. Therefore, Option B may or may not support speeds of 1.5 Mbps, so it is not the correct answer.

Option C) USR - USR (U.S. Robotics) is a brand that produces modems and networking equipment. However, the specific technology or product associated with "USR" is not provided in the question. Without knowing the specific context, it is not possible to determine whether USR supports speeds of 1.5 Mbps. Therefore, Option C cannot be determined as the correct answer.

Option D) ATM - Asynchronous Transfer Mode (ATM) is a networking technology that transmits data in fixed-size cells. ATM can support various speeds, including 1.5 Mbps. Therefore, Option D is a possible correct answer.

Option E) T1 - T1 is a dedicated digital communication line that supports a data rate of 1.544 Mbps. This speed is higher than 1.5 Mbps. Therefore, Option E is the correct answer.

The correct answer is Option E) T1. This option is correct because T1 supports speeds higher than 1.5 Mbps.

To answer this question, we need to understand the different categories of network cables.

Category 1 (Cat 1) cables are the oldest and do not support data transmission. They were primarily used for telephone communications.

Category 2 (Cat 2) cables were an improvement over Cat 1 cables, but they still do not support high-speed data transmission. They were also used for telephone communications.

Category 3 (Cat 3) cables can support data transmission at up to 10 Mbps. They were commonly used for Ethernet networks in the past.

Category 4 (Cat 4) cables can support data transmission at up to 16 Mbps. They were also used for Ethernet networks but are less common today.

Category 5 (Cat 5) cables can support data transmission at up to 100 Mbps. They became widely used for Ethernet networks and are still commonly used today.

Based on this information, we can see that the correct answer is E) Category 5. This cable can support a speed of 100 Mbps.

To answer this question, you need to understand the OSI (Open Systems Interconnection) model. The OSI model is a conceptual framework that standardizes the functions of a communication system into seven different layers.

The MAC (Media Access Control) sublayer is a part of the Data Link layer, which is the third layer of the OSI model. The Data Link layer is responsible for the reliable transfer of data over a physical link. It provides error detection and correction, as well as flow control between two directly connected nodes.

The Data Link layer is divided into two sublayers: the Logical Link Control (LLC) sublayer and the MAC sublayer. The LLC sublayer handles the flow control and error checking for the data link, while the MAC sublayer is responsible for controlling access to the physical medium.

Therefore, the correct answer is:

C. Data Link

To answer this question, you need to understand what an IP address is and how it is represented.

An IP (Internet Protocol) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main purposes: identifying the host or network interface, and providing the location of the host in the network.

IPv4 (Internet Protocol version 4), which is the most widely used version of IP, uses a 32-bit address format. This means that an IPv4 address consists of 4 bytes or 32 bits.

Option A) True - This option is correct because an IP address does consist of 4 bytes.

Option B) False - This option is incorrect because an IP address does consist of 4 bytes.

The correct answer is A) True.

To answer this question, you need to understand the purpose of each file listed.

Option A) HOSTS - This option is correct. The HOSTS file is a local file on a workstation that resolves names similar to a DNS server. It contains a list of IP addresses and corresponding hostnames. When a user on the workstation tries to access a website or network resource, the computer first checks the HOSTS file to see if there is a match for the hostname. If there is a match, the IP address from the HOSTS file is used to connect to the resource directly, bypassing the DNS server.

Option B) DHCP - This option is incorrect. DHCP (Dynamic Host Configuration Protocol) is a network protocol used to assign IP addresses and other network configuration settings to devices on a network. While DHCP can provide IP addresses to workstations, it does not resolve names similar to a DNS server.

Option C) DNSHOSTS - This option is incorrect. There is no standard file named DNSHOSTS that resolves names similar to a DNS server. The HOSTS file is the correct file for this purpose.

Option D) NAMEHOSTS - This option is incorrect. There is no standard file named NAMEHOSTS that resolves names similar to a DNS server. The HOSTS file is the correct file for this purpose.

Option E) SMHOSTS - This option is incorrect. There is no standard file named SMHOSTS that resolves names similar to a DNS server. The HOSTS file is the correct file for this purpose.

The correct answer is A) HOSTS. This option is correct because the HOSTS file on a workstation resolves names similar to a DNS server by mapping hostnames to IP addresses.
