1. Consider a CORBA-based modeling of the interface table that uses two approaches—a single

method that returns all the interfaces similar to a SNMPGetBulk and separate methods for each

interface similar to SNMPGet (a one–one mapping from SMI to IDLs).

(a) Which of the approaches is more suitable?

(b) Explain why it is more suitable

2. In a Management system at a Service Provider, it is required to query a device for SysUptime,

tcpActiveOpens, tcpPassiveOpens, and tcpAttempts. A designer Anil wants to use SNMP for this

while Bina wants to use CORBA (1 method call for SysUptime, 1 for the remaining 3 parameters).

Which of their approaches uses less bandwidth? Why?

This NMS also has to retrieve the ipRouteTable, which has about 10,000 rows. Anil suggests

SNMPv2 GetBulk command, while Bina prefers CORBA (1 method to fetch the table). Whose

approach results in less bandwidth being used? Why?
