Free Microsoft Networking Fundamentals v1 (98-366) Question and Answers — Questions and Answers
Question 1: A network must be split into three subnets. Which equipment ought you to employ?
- Router (Correct answer)
- Bridge
- Segmenter
- Hub
Correct answer: Router
A router is a network device that operates at the Network layer (Layer 3) and is specifically designed to connect different networks or subnets. Its primary function is to forward data packets between these distinct network segments based on IP addresses. To split a single network into multiple subnets, a router is essential for managing traffic flow and enabling communication between them.
Question 2: Switching from an unmanaged switch to a managed switch has several benefits, including:
- Reduce collision domains
- Route between networks
- Support multiple VLANS (Correct answer)
- Manage the routing tables
Correct answer: Support multiple VLANS
A key benefit of managed switches over unmanaged switches is their ability to support Virtual Local Area Networks (VLANs). VLANs allow network administrators to logically segment a single physical network into multiple broadcast domains, improving security and network performance. Managed switches provide the configuration options necessary to create, configure, and manage these VLANs, which unmanaged switches cannot do.
Question 3: You should utilize a to directly link two computers' Ethernet network interface cards (NICs).
- Straight cable
- Rollover cable
- Coaxial cable
- Crossover cable (Correct answer)
Correct answer: Crossover cable
To directly connect two computers' Ethernet Network Interface Cards (NICs) without an intervening switch or hub, a crossover cable is required. Standard Ethernet cables (straight-through) are designed to connect a NIC to a switch/hub, where the transmit pins on one end connect to receive pins on the other. A crossover cable, however, internally swaps the transmit and receive pairs, allowing two identical devices to communicate directly.
Question 4: A router's purpose is to:
- Forward traffic to other networks (Correct answer)
- Broadcast routing tables to clients
- Store tables for name resolution
- Provide IP subnet masks for hosts
Correct answer: Forward traffic to other networks
The fundamental purpose of a router is to connect different networks and forward data packets between them. Routers examine the destination IP address of incoming packets and use their routing tables to determine the best path to send those packets towards their destination, which may be on a different network segment or even across the internet. This enables communication between disparate networks.
Question 5: If a router is unable to identify the packet's subsequent hop, it will:
- Store the packet in the memory buffer
- Forward the packet to the default route (Correct answer)
- Send the packet back to the packet's source
- Broadcast the packet
Correct answer: Forward the packet to the default route
When a router receives a packet and cannot find a specific entry in its routing table that matches the destination IP address, it will forward the packet to its default route. The default route acts as a 'route of last resort,' typically pointing to another router (often the gateway to the internet or a larger network) that is more likely to know how to reach the destination. If no default route is configured, the packet would be dropped.
Question 6: Which physical network topology connects every computer to a hub?
- Star (Correct answer)
- Ring
- Bus
- Mesh
Correct answer: Star
In a star topology, every computer or network device is individually connected to a central connecting device, typically a hub or a switch. This central device acts as a repeater or a traffic manager, forwarding data between the connected devices. This design makes it easy to add or remove devices and isolates cable failures to a single connection.
Question 7: A private network that enables data sharing between members of an organization is:
- Intranet (Correct answer)
- Internet
- Extranet
- Ethernet
Correct answer: Intranet
An intranet is a private network that uses Internet protocols and technologies (like TCP/IP, HTTP) but is accessible only to authorized users within a single organization. Its primary purpose is to facilitate internal communication, collaboration, and data sharing among employees. It functions like a private version of the internet, confined to the organization's boundaries.
