Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 272

A corporate policy requires PPPoE to be enabled and to maintain a connection with the ISP, even if no interesting traffic exists. Which feature can be used to accomplish this task?

Answer options

• A. TCP Adjust
• B. Dialer Persistent
• C. PPPoE Groups
• D. half-bridging

Correct answer:

Explanation

The correct answer is B. Dialer Persistent, as it allows the PPPoE connection to stay active regardless of traffic conditions. The other options do not provide the same functionality; TCP Adjust is related to TCP settings, PPPoE Groups manage multiple connections, and half-bridging pertains to a different networking concept.
