Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 20

Port security is enabled on a Cisco MDS 9000 Series Switch.
Which statement is true?

Answer options

• A. Port security can be enabled only globally and affects all VSANs.
• B. Any devices currently logged in must be added manually to the device database.
• C. Auto-learning is always enabled automatically when port security is enabled.
• D. Cisco Fabric Services must be disabled before enabling port security.

Correct answer: C

Explanation

The correct answer is C because when port security is enabled, auto-learning of devices is automatically activated to facilitate the process of adding devices to the database. Option A is incorrect as port security can be configured on a per-VSAN basis. Option B is wrong because auto-learning helps in automatically populating the device database. Option D is also incorrect because there is no requirement to disable Cisco Fabric Services to enable port security.
