- Inputs:
- Exam Version: CCNA 200-125 (2018)
- Calculation Type: Subnetting
- Exam Environment: Authorized Test Center
- Expected Output (Policy): No calculator allowed. Candidate must manually calculate the subnet mask, block size, network addresses, and host ranges using the provided scratchpad.
- Interpretation: The candidate would need to quickly determine that a /27 mask means 255.255.255.224, a block size of 32. The subnets would be 192.168.10.0, 192.168.10.32, 192.168.10.64, etc. The third subnet starts at 192.168.10.64, with a broadcast of 192.168.10.95, making the valid host range 192.168.10.65 to 192.168.10.94. All these steps require mental math and careful use of the scratchpad, reinforcing why you cannot use a calculator on the CCNA 2018.
Example 2: Binary to Decimal Conversion
Scenario: A question requires converting the binary address 11001010 to its decimal equivalent.
- Inputs:
- Exam Version: CCNA 200-125 (2018)
- Calculation Type: Binary/Hexadecimal Conversion
