Bridges operate at the physical layer. T/F?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
False. Bridges operate at the data link layer, which is the second layer in the OSI model. The physical layer is responsible for the transmission of raw data over a physical medium, while the data link layer is responsible for the reliable transmission of data between adjacent nodes on a network. Bridges are used to connect two or more network segments at the data link layer, making them operate at this layer rather than the physical layer.Rate this question:

After building a small network and connecting it to your ISP you notice that the clients are unable to browse the Internet. You call your ISP and he asks for the information configured on your router. You present the required information to him. He says the information is as it should be. You browse the net from the computer directly connected to your DSL modem and you are able to do so. What could the problem be?
- A.
Incorrect IP configuration
- B.
DNS not configured on the workstations
- C.
DNS server not set on the DHCP server
- D.
Default gateway not set on the workstations
Correct Answer
D. Default gateway not set on the workstationsExplanation
The problem could be that the default gateway is not set on the workstations. The default gateway is the IP address of the router that connects the local network to the internet. Without a default gateway, the workstations do not know how to route their network traffic to the internet. This would explain why they are unable to browse the internet even though the router's configuration and the ISP's information are correct.Rate this question:

Which of the following functions is a firewall capable of? Choose two
- A.
Block traffic
- B.
Permit traffic
- C.
Verify company policies
- D.
Authenticate internal users
Correct Answer(s)
A. Block traffic
B. Permit trafficExplanation
A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and an untrusted external network, such as the internet. One of the main functions of a firewall is to block or permit traffic based on these rules. By blocking traffic, the firewall can prevent unauthorized access and potential threats from entering the network. On the other hand, by permitting traffic, the firewall allows legitimate and authorized traffic to pass through. Additionally, firewalls can also verify company policies to ensure compliance and authenticate internal users to control access to the network.Rate this question:

Which of the following media access scheme does the token ring network use?
- A.
Token passing
- B.
CSMA/CD.
- C.
CSMA/CA.
- D.
None of the above
Correct Answer
A. Token passingExplanation
Token passing is the correct answer because the token ring network uses a token passing media access scheme. In this scheme, a token is passed around the network, and only the device holding the token is allowed to transmit data. This ensures that there are no collisions and guarantees fair access to the network for all devices. CSMA/CD and CSMA/CA are different media access schemes used in other types of networks, not in token ring networks.Rate this question:

How many maximum subnet IDs are possible in this situation? Class C network 221.222.162.0 255.255.255.0, subnet by borrowing 5 bits,
- A.
30 subnet IDs
- B.
20 subnet IDs
- C.
22 subnet IDs
- D.
32 subnets
Correct Answer
A. 30 subnet IDsExplanation
By borrowing 5 bits, we can create 2^5 = 32 subnets. However, since the question asks for the maximum subnet IDs, we need to subtract 2 from the total number of subnets. This is because the first subnet ID (all 0s) is reserved as the network address, and the last subnet ID (all 1s) is reserved as the broadcast address. Therefore, the maximum number of subnet IDs possible in this situation is 32 - 2 = 30 subnet IDs.Rate this question:

You have just connected a brand new dial-up modem that does not require drivers. You have configured the modem and shared it for your Peer-to-Peer network as per the instructions in the manual. Your system just refuses to recognize this PCI modem. What must you do next? Select 2
- A.
Change the slot.
- B.
Return the modem.
- C.
Try restarting your computer.
- D.
None of the above.
Correct Answer(s)
A. Change the slot.
C. Try restarting your computer.Explanation
If the system refuses to recognize the PCI modem that has been configured and shared for the Peer-to-Peer network, the first step would be to try restarting the computer. This can help refresh the system and potentially resolve any temporary issues that may be causing the recognition problem. If restarting the computer does not work, the next step would be to change the slot where the modem is connected. This can help troubleshoot any potential issues with the current slot and ensure proper recognition of the modem by the system.Rate this question:

You wish to segregate your sales department logically in terms of the products that they deal with. There are 3 such groups. The data intended for Product 1 must not reach Product 2 and 3 and so on. Which of the following would be an ideal solution for this situation?
- A.
SNMP
- B.
VLANs
- C.
Routing
- D.
RMON probe
Correct Answer
B. VLANsExplanation
VLANs (Virtual Local Area Networks) would be an ideal solution for segregating the sales department logically in terms of the products they deal with. VLANs allow for the creation of separate virtual networks within a physical network, enabling the isolation of traffic between different groups or departments. By assigning each product group to a different VLAN, the data intended for one product group will not reach the other groups, ensuring logical segregation and enhancing network security.Rate this question:

Which of the following is true regarding this representation of IP address?204.202.10.32/29
- A.
29 bits of the 32 bits are reserved for host ID.
- B.
3 bits of the 32 bits are reserved for the network ID.
- C.
29 bits of the 32 bits are reserved for the network ID.
- D.
None of the above
Correct Answer
C. 29 bits of the 32 bits are reserved for the network ID.Explanation
In this representation of the IP address 204.202.10.32/29, the "/29" indicates that the first 29 bits of the 32-bit IP address are reserved for the network ID. This means that only the remaining 3 bits are available for the host ID. Therefore, the correct answer is that 29 bits of the 32 bits are reserved for the network ID.Rate this question:
