Which of the following statements about MPLS (multiprotocol label switching) is not true?
a MPLS connections are highly scalable for businesses, which means a business can add more and longer connections for less cost than similarly scaled leased lines.
b Customers can prioritize their own traffic across the WAN (wide area network) according to QoS (quality of service) attributes, such as giving VoIP traffic higher priority over email traffic.
c The ability to label traffic offers more reliability, predictability, and security (when properly implemented) than when using cheaper connections over the open Internet.
d MPLS does not offer any decreased latency.
