   Refer to the exhibit. What is the cause of poor performance on router R19?

   • Aexcessive collisions
   • Bexcessive CRC errors
   • Cport oversubscription
   • Dspeed and duplex mismatch

   Show answer

   Answer: C

   Explanation

   The key indicator in the output is the "Total output drops: 135298429". This suggests a significant number of packets are being dropped because the interface cannot handle the traffic, which is typically due to port oversubscription (answer C). While there are some CRC errors and collisions, these numbers are much smaller compared to the massive number of output drops, which points toward the port being overwhelmed with traffic, a classic sign of oversubscription rather than issues like collisions or CRC errors. So the correct answer is C. port oversubscription.

3. Question 383 · 1334 in bank

   Why is UDP more suitable than TCP for applications that require low latency, such as VoIP?

   • AUDP uses sequencing data for packets to arrive in order, and TCP offers the capability to receive packets in random order.
   • BTCP uses congestion control for efficient packet delivery, and UDP uses flow control mechanisms for the delivery of packets
   • CUDP reliably guarantees delivery of all packets, and TCP drops packets under heavy load.
   • DTCP sends an acknowledgment for every packet that is received, and UDP operates without acknowledgments.
