Which UDP characteristic does this scenario describe?

A network administrator uses IP SLA to measure UDP performance and notices that packets on one router have a higher one-way delay compared to the opposite direction.

D . nonsequencing unordered packets
E . jitter

Answer: A

Explanation:

Cisco IOS IP SLAs provides a proactive notification feature with an SNMP trap. Each measurement operation can monitor against a pre-set performance threshold. Cisco IOS IP SLAs generates an SNMP trap to alert management applications if this threshold is crossed. Several SNMP traps are available: round trip time, average jitter, one-way latency, jitter, packet loss, MOS, and connectivity tests. Here is a partial sample output from the IP SLA statistics that can be seen: router#show ip sla statistics 1Round Trip Time (RTT) for Index 55 Latest RTT: 1 ms Latest operation start time: *23:43:31.845 UTC Thu Feb 3 2005 Latest operation return code: OK RTT Values: Number Of RTT: 10 RTT Min/Avg/Max: 1/1/1 milliseconds Latency one-way time: Number of Latency one-way Samples: 0 Source to Destination Latency one way Min/Avg/Max: 0/0/0 milliseconds Destination to Source Latency one way Min/Avg/Max: 0/0/0 milliseconds
