    • PC1 will not be able to communicate with PC2 since PC2 is in a different subnet and PC1 does not have a default gateway configured.

    • PCI will perfonn an ARP broadcast to resolve PC2s IP address to MAC address since both PCs have the same subnet mask and communication will occur.

    • PC2 and PC2 will not be able to communicate since both PCs must have the same default gateway

    • PC1 will send traffic to the default gateway at 192.168.100.1 since PC2 is in a different subnet and communication will occur.

    Correct Answer
    A. PC1 will not be able to communicate with PC2 since PC2 is in a different subnet and PC1 does not have a default gateway configured.
    Explanation
    PC1 will not be able to communicate with PC2 since PC2 is in a different subnet and PC1 does not have a default gateway configured. This means that PC1 does not have a route to reach PC2's subnet. Without a default gateway, PC1 can only communicate with devices on its own subnet. In order for PC1 to communicate with PC2, it would need to have a default gateway configured, which would provide a route to reach PC2's subnet.

    A. CIDR
    Explanation
    221.17.101.223/28 is an example of CIDR notation, which stands for Classless Inter-Domain Routing. CIDR notation is used to represent IP addresses and their associated subnet masks. In this notation, the IP address is followed by a slash (/) and the number of bits in the subnet mask. In this case, the subnet mask is 28 bits, indicating that the first 28 bits of the IP address are the network address and the remaining 4 bits are the host address.

    QUESTION NO: 188 Which of the following is the BEST reason to implement QoS when real-time applications are in use in the network?

    • Increase network reliability.

    • Prioritize delay sensitive traffic.

    • Increase network bandwidth of delay sellSitive traffic.

    • Prioritize bulk traffic.

    Correct Answer
    A. Prioritize delay sensitive traffic.
    Explanation
    Implementing Quality of Service (QoS) is important when real-time applications are in use because it allows for the prioritization of delay-sensitive traffic. Real-time applications, such as video conferencing or VoIP, require low latency and minimal packet loss to function properly. By implementing QoS, network administrators can allocate sufficient bandwidth and prioritize the delivery of these time-sensitive packets, ensuring a smooth and uninterrupted user experience. This helps to minimize delays and improve the overall performance of real-time applications on the network.

    QUESTION NO: 189 Which of the following would be an appropriate use of an EGP?

    • Unequal cost load balancing over a switched network.

    • Advertising a /24 to an upstream provider.

    • Periodic updates to neighbors on the LAN.

    • Routing between VLANs on an Ethernet network.

    Correct Answer
    A. Advertising a /24 to an upstream provider.
    Explanation
    An Exterior Gateway Protocol (EGP) is used to exchange routing information between different autonomous systems (AS). Advertising a /24 to an upstream provider would be an appropriate use of an EGP as it involves announcing the availability of a specific network prefix to the upstream provider. This allows the provider to direct traffic towards that network.

    QUESTION NO: 191 A network technician is installing a series off three access points to cover the entire wing of a building. Each access point has a wired conection and 802.11g is being used for the wireless transmission. Which of the following channels should be used for the access points?

    • Channels 7-11-1

    • Channels 1-6-11

    • Channels 1-3-5

    • Chalmeis 2-4-6

    Correct Answer
    A. Channels 1-6-11
    Explanation
    The access points should be set to channels 1, 6, and 11. This is because these channels do not overlap with each other and provide the best coverage without interference. By using these channels, the access points can transmit on different frequencies, reducing the chances of signal interference and ensuring a stable wireless connection for users in the building.

    QUESTION NO: 192* A technician is working on a new employees workstation in the accounting department? The workstation needs access to the accounting server. Currently the technician notices that the employee can only access the Internet. Which of the following would the technician need to verify?

    • Correct VPN setting

    • Correct VLAN setting

    • Correct DNS setting

    • Correct WINS setting

    Correct Answer
    A. Correct VLAN setting
    Explanation
    The technician would need to verify the correct VLAN setting. VLANs (Virtual Local Area Networks) are used to separate network traffic and isolate devices into different logical networks. If the workstation can only access the Internet and not the accounting server, it suggests that it may be on the wrong VLAN, which is preventing it from accessing the server. By verifying the VLAN setting, the technician can ensure that the workstation is on the correct network to access the accounting server.

    QUESTION NO: 194 Which of the following is part of the TCP/IP protocol suite?

    • UDP

    • IPX

    • NetBEUI

    • SPX

    Correct Answer
    A. UDP
    Explanation
    UDP (User Datagram Protocol) is indeed part of the TCP/IP protocol suite. TCP/IP is a set of protocols that allows computers to communicate over a network. UDP is one of the core protocols in this suite, providing a connectionless and unreliable transmission of data. Unlike TCP, UDP does not guarantee the delivery of packets or the order in which they are received. It is commonly used for applications that require low latency and can tolerate packet loss, such as real-time streaming or online gaming. IPX, NetBEUI, and SPX are not part of the TCP/IP suite.

    QUESTION NO: 195 The function of a tone generator is to generate a tone to test:

    • Continuity

    • Signal strength.

    • Impedance.

    • Signal feedback.

    Correct Answer
    A. Continuity
    Explanation
    A tone generator is used to generate a continuous tone signal that can be used to test the continuity of a circuit or a cable. By connecting the tone generator to one end of the circuit and using a probe or a receiver at the other end, the presence of the tone indicates that there is a continuous path for the signal to flow through, confirming the continuity of the circuit or cable. This is useful for troubleshooting and identifying breaks or faults in the wiring.

    QUESTION NO: 196* A technician is not able to ping a server by the FQDN but can by the IP. Which of the following should the technician check?

    • Ensure that WINS is configured

    • Ensure that the DNS is configured

    • Ensure the MAC address is correct

    • Ensure that the IP address is correct

    Correct Answer
    A. Ensure that the DNS is configured
    Explanation
    The technician should check if the DNS is configured correctly. The FQDN (Fully Qualified Domain Name) is used to resolve the IP address of a server using DNS. If the technician is unable to ping the server by the FQDN but can by the IP, it suggests that the DNS is not able to resolve the FQDN to the correct IP address. Therefore, checking the DNS configuration is necessary to ensure proper resolution of the FQDN.

    QUESTION NO: 197 Which of the following cable types allows for the maximum cable run distance?

    • Coaxial

    • Multi-mode fiber

    • Single-mode fiber

    • CAT3

    Correct Answer
    A. Single-mode fiber
    Explanation
    Single-mode fiber allows for the maximum cable run distance compared to the other cable types mentioned. This is because single-mode fiber has a smaller core size and uses a single beam of light to transmit data, allowing for less signal loss and greater distance coverage. Coaxial cable, multi-mode fiber, and CAT3 cables have larger core sizes and are more susceptible to signal loss over longer distances.
