CCNA: Cisco Certified Network Associate — Question 1118

Which Rapid PVST+ feature should be configured on a switch port to immediately send traffic to a connected server as soon as it is active?

Answer options

• A. portfast
• B. uplinkfast
• C. BPDU guard
• D. loop guard

Correct answer: A

Explanation

The correct answer is A, 'portfast', because this feature allows a switch port to transition from blocking to forwarding mode immediately when it detects a connection, thus reducing the time it takes for a device to start communicating. Options B (uplinkfast), C (BPDU guard), and D (loop guard) do not provide this immediate activation for endpoint devices; instead, they serve different purposes related to network stability and protection.
