  • Continuous Application Protocol

Question 7)
Which statement is TRUE with respect to the IEEE 802.15.4 standard?
  • It is a low data-rate standard. 
  • Used for architecting wireless PANS 
  • Uses only two layers - PHY and MAC 
  • All of these


Question 8)

  • RIPv2
  • AODV 
  • DSDV 
  • OSPF


Question 9)
XMPP protocol is
  • Message-oriented middleware based on Extensible Markup Language (XML)

  • Targeted QoS 
  • High speed protocol 
  • All of these


Question 12)
