Question

Which Security policy set should be used to ensure that a policy is applied first?

Options

  • ALocal firewall policy
  • BShared pre-rulebase
  • CParent device-group pre-rulebase
  • DChild device-group pre-rulebase

Explanation

The Shared pre-rulebase ensures that policies are applied first because it is processed before any other rulebases (device-group or local) on the firewall.

Common mistakes.

  • A. Local firewall policies are processed last, after Shared and Device Group policies, so they would not be applied first.
  • C. Parent device-group pre-rulebase policies are processed after the Shared pre-rulebase, but before child device-group or local policies, meaning they are not applied first overall.
  • D. Child device-group pre-rulebase policies are processed after Shared and parent device-group policies, meaning they are not applied first.
