Free MTA Networking Questions and Answers — Questions and Answers
Question 1: A client has requested a network setup for his home. The network has to be cost-effective, and easy to extend and implement. Further more, the client wants his workstations connected by a single cable. Which of the following network topologies should you use?
- A star network topology.
- A bus network topology. (Correct answer)
- A mesh network topology.
- A ring network topology.
Correct answer: A bus network topology.
A bus network topology connects all devices to a single central cable, or 'bus.' This setup is cost-effective and straightforward to implement for small networks, as it requires minimal cabling. It also offers ease of extension by simply adding more devices to the shared cable, making it a suitable choice for a home network requiring simplicity and expandability.
Question 2: You have recently designed a home office network for a client that includes a switch. Which of the following are TRUE with regards to network switches?
- It keeps track of the MAC addresses attached to each of its ports and directs traffic intended for a particular address only to the port to which is attached. (Correct answer)
- It keeps track of the IP addresses attached to each of its ports and directs traffic intended for a particular address only to the port to which it is attached.
- It operates at the Physical layer of the OSI model.
- It operates at the Data-Link layer of the OSI model.
Correct answer: It keeps track of the MAC addresses attached to each of its ports and directs traffic intended for a particular address only to the port to which is attached.
A network switch operates at the Data Link layer (Layer 2) of the OSI model. Its primary function is to learn the MAC addresses of devices connected to each of its ports and store this information in a MAC address table. When a data frame arrives, the switch examines the destination MAC address and intelligently forwards the frame only to the specific port where the destination device is attached, significantly reducing unnecessary network traffic and improving efficiency.
Question 3: As part of a training exercise, you have been asked to identify the layer that allows applications and a number of useful functions access to the network. Which of the following options represents your response?
- The document layer.
- The application layer. (Correct answer)
- The system layer.
- The Data-link layer.
Correct answer: The application layer.
The application layer is the highest layer (Layer 7) in the OSI model, providing network services directly to end-user applications. It enables applications to access network resources and perform various functions such as file transfer, email, and web browsing. This layer interacts with software applications that implement a communicating component, allowing users to interact with the network.
Question 4: You have been tasked with making sure that a client's network includes a server that converts NetBIOS names to IP addresses. Which of the following actions should you take?
- You should consider adding a DHCP server to the client's network.
- You should consider adding a DNS server to the client's network.
- You should consider adding a Web server to the client's network.
- You should consider adding a WINS server to the client's network. (Correct answer)
Correct answer: You should consider adding a WINS server to the client's network.
A WINS (Windows Internet Name Service) server is specifically designed to resolve NetBIOS names to IP addresses. In older Windows-based networks, NetBIOS names were used for identifying network resources. While DNS has largely superseded WINS for modern IP networks, a WINS server would be essential if the client's network still relies on NetBIOS names for resource identification and requires their conversion to IP addresses.
Question 5: A clients network is made up of two network segments, named Subnet A and Subnet B. DHCP clients are located on Subnet A. A DHCP server on Subnet B. You need to make sure that DHCP clients are able to connect to the server. Which of the following actions should you take?
- You should make sure that the RRAS service is configured.
- You should make sure that WEb service is configured.
- You should make sure that the DNS service is configured.
- You should make sure that the DHCP relay agent service is configured. (Correct answer)
Correct answer: You should make sure that the DHCP relay agent service is configured.
DHCP (Dynamic Host Configuration Protocol) clients typically use broadcast messages to discover a DHCP server. If the DHCP server is located on a different network segment (subnet) than the clients, these broadcast messages will not traverse routers by default. Therefore, a DHCP relay agent service must be configured on the client's subnet to receive these broadcast requests and forward them as unicast messages to the DHCP server, enabling clients to obtain IP addresses across subnets.
