Which statement is false?

Question

Options

• Acustom URL categories cannot contain IP addresses
• Bcustom URL categories cannot override predefined URL categories
• Ccustom URL categories can contain domain names
• Dcustom URL categories can use regular expressions

• A
  91% (21)
• B
  4% (1)
• D
  4% (1)

Explanation

Option A is false because custom URL categories can contain IP addresses - both individual IPs and subnets are valid entries alongside domain names, making the claim that they "cannot" a clear inversion of the truth.

Why the distractors are correct (and therefore not the answer):

• B is true: custom categories exist alongside predefined ones and cannot directly modify or replace the built-in URL filtering database entries.
• C is true: domain names are the most common entry type for custom URL categories.
• D is true: regular expressions are supported, allowing flexible pattern-based URL matching.

Memory tip: Think "custom = flexible." Custom URL categories accept IP addresses, domain names, and regular expressions - three entry types. If you see a statement claiming a custom category "cannot" include something as basic as an IP address, that's your red flag.
