JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing — Question 5

Which statement is true about using an OSPF import policy?

Answer options

• A. Import policies are not allowed in OSPF, applying the policy will do nothing.
• B. Applying an import policy to OSPF may block normal LSA flooding.
• C. Import policies are allowed only for external route types.
• D. Applying this policy will cause a commit failure.

Correct answer: C

Explanation

The correct answer is C because OSPF import policies can only be applied to external routes, which is a limitation of the protocol. Option A is incorrect as it misstates the applicability of import policies in OSPF. Option B is misleading because while it is true that misconfigured policies might affect LSA flooding, it does not directly relate to the allowance of import policies. Option D is incorrect as applying an import policy does not inherently lead to a commit failure.
