A network engineer receives reports about poor voice quality issues at a remote site. The network engineer does a packet capture and sees out-of-order packets being delivered.
Which option can cause the VOIP quality to suffer?
A . traffic over backup redundant links
B . misconfigured voice vlan
C . speed duplex link issues
D . load balancing over redundant links
Answer: D
Explanation:
In traditional packet forwarding systems, using different paths have varying latencies that cause out of order packets, eventually resulting in far lower performance for the network application. Also , if some packets are process switched quickly by the routing engine of the router while others are interrupt switched (which takes more time) then it could result in out of order packets. The other options would cause packet drops or latency, but not out of order packets.
