    Joe, a user, is unable to reach websites, but is able to ping several Internet IPv4 addresses. Which of the following is the MOST likely problem?

    • Incorrect subnet mask

    • Incorrect DNS

    • Missing default gateway

    • Incorrect IPv6 address

    Correct Answer
    A. Incorrect DNS
    Explanation
    The most likely problem in this scenario is an incorrect DNS configuration. DNS (Domain Name System) is responsible for translating domain names into IP addresses. If Joe is unable to reach websites but can successfully ping IP addresses, it suggests that his network connectivity is functioning properly. However, the fact that he cannot access websites indicates a problem with the DNS settings, as the translation from domain names to IP addresses is not occurring correctly.

    Joe, a network administrator, would like to ensure that the footprint of the company’s wireless coverage is limited to the office borders, located on the premises. Which of the following features should he adjust on all of the company’s WAPs to make this change?

    • SSID masking

    • PPPOE

    • Transmission power

    • Encryption technology

    Correct Answer
    A. Transmission power
    Explanation
    To limit the footprint of the company's wireless coverage to the office borders, Joe should adjust the transmission power on all of the company's WAPs. By reducing the transmission power, the signal strength will be decreased, resulting in a smaller coverage area. This will ensure that the wireless network is only accessible within the office premises and not beyond its borders.
