      It might even be the answer F – From IPv4, run the DHCP Policy Configuration Wizard because it allows you to block MAC addresses, but to create a DHCP policy is within scope, so I believe the answer is wrong.

      The correct answer would be “D – From IPv4, create a new filter.”

  1. Chris C says:

    An exclusion range prevents the DHCP server from issuing IP addresses in that range. Because you have machines that already use those addresses. It doesn’t prevent clients from accessing the server. The question specifically states you are to prevent machines with a physical, i.e. MAC address, from connecting, which is MAC address filtering.

    Answer is F. Because the question states only a prefix of the macc address. You can deny clients an IP lease with a macc address prefix only in a DHCP policy. In a filter you have to configure the whole macc address.

    1. Fact Checker says:

      I agree. F is the answer because in the Wizard you can use wildcards. This would allow you to do 98-5F*. An Ip Filter requires whole mac addresses. Exclusions ranges prevent any devices from using those IPs.
