Main areas to Focus for getting NMS/EMS Quality Assurance job in Telecom/Networking field, but not limited to: EMS Vs NMS SNMP V1/V2/V3 or Any other protocols like CORBA,TL1 &CMIP.  Good Understanding on FCAPS. One of the scripting language like Shell Script or TCL or Perl as per ur interest Good Understanding of Operating systems like Windows,Linux & Solaris. Basic Switching & Routing. Mainly STP,DHCP,ARP/RARP,RIP,OSPF & BGP protocols TDM E1/T1 Testing concepts; Feature testing, Regression testing, Sanity tests, performance testing. Also, Testing models like Waterfall model & agile model.       If u want to be in software development in Telecom/Networking field then instead of point 8 above u should be strong in C or C++ or Java. Everything else remains same.

Do you want to crack interview on NMS? Well, you are at right place then J FAQs on NMS (mainly NMS with SNMP):- What is NMS? => It’s a Network Management system which  manages the network nodes like routers, switches, access nodes, servers, hosts and many more. NMS is mainly concerned with how the network nodes are tied up together and hence manage them in terms of networks rather than managing individual nodes. NMS is 3 rd layer in TMN architecture. What are the most common protocols used by NMS to communicate with the nodes? =>SNMP,CORBA,TL1,SSH,Telnet e.tc Which transport layer protocol is used by SNMP? What are the ports used? => SNMP normally uses UDP protocol. NMS uses port 161 to communicate with the agent and listens to port 162 for the traps sent by the agents. How the reliability is achieved in NMS with SNMP? => As UDP is unreliable protocol, there may be chance of traps getting lost. Henc
