JN0-231 PDF 109 Questions

Which two criteria should a zone-based security policy include? (Choose two.)

  1. a source port
  2. a destination port
  3. zone context
  4. an action

Answer(s): A,B

Explanation:

A security policy is a set of statements that controls traffic from a specified source to a specified destination using a specified service. A policy permits, denies, or tunnels specified types of traffic unidirectionally between two points.

Each policy consists of:

A unique name for the policy.
A from-zone and a to-zone, for example: user@host# set security policies from-zone untrust to-zone untrust
A set of match criteria defining the conditions that must be satisfied to apply the policy rule. The match criteria are based on a source IP address, destination IP address, and applications. The user identity firewall provides greater granularity by including an additional tuple, source-identity, as part of the policy statement.
A set of actions to be performed in case of a match--permit, deny, or reject.

Accounting and auditing elements--counting, logging, or structured system logging.
