a. adopt an all-IP switching capability
b. ensure greater spectral efficiency by adopting OFDM
c. improve voice quality so that it is on par with the PSTN
d. ensure interface with heterogenous networks such a WLANs
What was one of the goals of IMT-Advanced?
a. support both circuit-switched and packet-switched concepts
b. adopt CDMA technology
c. adopt IP packet switched technology
d. ensure backward compatibility with 1G analog voice streams
a. adopt an all-IP switching capability
b. ensure greater spectral efficiency by adopting OFDM
c. improve voice quality so that it is on par with the PSTN
d. ensure interface with heterogenous networks such a WLANs
Explanation / Answer
Ans:1
b. 200.100.26.64
200.100.26.0/26 belongs to class C
subnet mask of class C is 255.255.255.0
now we are borrowing 2 bit for subnetting hence
subnet mask = 255.255.255.192
22 = 4 subnets
block size of subnetwork = 254-192 = 64 i.e 0...64, 128, 192
hence first address = 192.168.26.0
second = 192.168.26.64
third = 192.168.26.128
fourth = 192.168.26.192
only 192.168.0.64 mathces hence option B is correct.
===============================================================
Ans:2
c. 223.10.64.64
host 223.10.64.70/26 lies between 223.10.64.64 to 223.10.64.127
Explantion same as question 1.
===============================================================
Ans:3
ensure greater spectral efficiency by adopting OFDM
Ans:4
adopt IP packet switched technology
