Correct Answer - Option 4 : 205.16.39.44
Answer: Option 4
Explanation:
Given first address: 205.16.32.0
Supernet mask: 255.255.248.0
Option 1: 205.16.42.56
performing bitwise and operation with supernet mask
11001101.00010000.00101010.00111000
11111111 .11111111 . 11111000 .00000000
-----------------------------------------------------------
11001101.00010000.00101000. 00000000
≡ 205.16.40.0 ≠ 205.16.32.0
Hence this is not the correct Option.
Option 2: 205.17.32.76
performing bitwise and operation with supernet mask
11001101.00010001.00100000.01001100
11111111 .11111111 . 11111000 .00000000
-----------------------------------------------------------
11001101.00010001.00100000. 00000000
≡ 205.17.32.0 ≠ 205.16.32.0
Hence this is not the correct Option.
Option 3: 205.16.31.10
performing bitwise and operation with supernet mask
11001101.00010000.00011111.00001010
11111111 .11111111 . 11111000 .00000000
-----------------------------------------------------------
11001101.00010000.00011000. 00000000
≡ 205.16.24.0 ≠ 205.16.32.0
Hence this is not the correct Option.
Option 4: 205.16.39.44
performing bitwise and operation with supernet mask
11001101.00010000.00100111.00101100
11111111 .11111111 . 11111000 .00000000
-----------------------------------------------------------
11001101.00010000.00010000. 00000000
≡ 205.16.32.0 == 205.16.32.0
Hence this is the correct Option.
