According to the following topology and configuration, R1 and R2 are connected through low-speed serial cables and PPP is used to encapsulate data link layer packets. When the Holdtime values of R1 and R2 are different, PPP negotiation and communication fail.
PPP negotiation and communication generally do not fail due to differences in Holdtime values. PPP is designed to negotiate parameters between devices to ensure connectivity, and the specific timing settings, such as the Holdtime, are typically less critical as long as they allow for successful exchanges of keepalive packets. disparities in these values alone won't cause the negotiation and communication process to fail.
B)FALSE ppp negotiation and communication doesn't fail
answer shoud be true
answer should be false,not true,
https://support.huawei.com/enterprise/de/doc/EDOC1100064352/e34143bf/ppp-timer-negotiate Correct Answer: False PPP negotiates between the endpoints the correct configuration and the timer configuration isn't an important factor as long as the 2 points are sending quick enough the answer to eachother, even than they are awaiting the transmittion of the answer, they don't close the connection.
Hard disagree. Correct answer: True https://support.huawei.com/enterprise/de/doc/EDOC1100064352/2a9183ae/timer-hold Quote: "On a low-speed link, the seconds parameter cannot be set to a small value because it may take a long time to transmit oversized packets on the link. If the interval for sending Keepalive packets is set to a small value, transmission of Keepalive packets is delayed. If an interface does not receive any Keepalive packet from the remote interface after five Keepalive intervals, the interface considers that the link fails."
