• Question 610:

  

  Refer to the exhibit, An engineer is asked to troubleshoot packet drops inside a network which option is true?

  A. HTTP traffic originated by the 10.10.10.0/24 subnet uses up to 10% of the interface bandwidth. However, if no congestion is present, no more bandwidth is allocated to HTTP traffic
  B. SMTP traffic originated by the 10.10.10.0/24 subnet uses up to 10% of the bandwidth, however, if no congestion is present, more bandwidth is allocated to SMTP traffic
  C. SMTP traffic originated by the 10.10.10.0/24 subnet uses up to 10% of the bandwidth. However , if no congestion is present, SMTP traffic above 10% of link bandwidth is dropped
