Free FC0-U71 sample questions

1. A junior network technician needs to convert the binary value 1010 to decimal for a VLAN ID configuration. What is the correct decimal equivalent?

   • A. 8 in decimal format
   • B. 10 in decimal format
   • C. 12 in decimal format
   • D. 16 in decimal format
   Show answer

   Correct: B. Binary 1010 equals 8 + 0 + 2 + 0 = 10 in decimal format, because binary position values from left to right are 8, 4, 2, and 1. The distractor options 8, 12, and 16 are incorrect because they represent binary values 1000, 1100, and 10000 respectively.

2. A systems administrator is reviewing MAC address formats in a network audit. Which notational system uses digits 0-9 and letters A-F to represent values?

   • A. Binary numbering system
   • B. Decimal numbering system
   • C. Hexadecimal numbering system
   • D. Octal numbering system
   Show answer

   Correct: C. The Hexadecimal numbering system is base-16 and uses digits 0-9 plus letters A-F to represent numerical values. Binary, Decimal, and Octal are incorrect because binary uses base-2 (0 and 1), decimal uses base-10 (0-9), and octal uses base-8 (0-7).

3. A computer student is calculating data transmission boundaries. How many individual bits make up one standard byte?

   • A. 4 bits (Nibble)
   • B. 8 bits (1 Byte)
   • C. 16 bits (Word)
   • D. 1024 bits (Kbit)
   Show answer

   Correct: B. A byte is defined by computing standards as containing exactly 8 bits. The distractor options 4 bits, 16 bits, and 1024 bits are incorrect because 4 bits is a nibble, 16 bits is a 2-byte word, and 1024 is a binary scaling factor rather than bits per byte.

4. A cloud administrator is cataloging storage tier capacities from smallest to largest. Which sequence represents the correct order of data units?

   • A. KB, MB, GB, TB (Kilobyte to Terabyte)
   • B. MB, KB, GB, TB (Megabyte to Terabyte)
   • C. GB, MB, KB, TB (Gigabyte to Terabyte)
   • D. TB, GB, MB, KB (Terabyte to Kilobyte)
   Show answer

   Correct: A. Data storage capacity increases sequentially from Kilobyte (KB) to Megabyte (MB), Gigabyte (GB), and Terabyte (TB). The alternative sequences are incorrect because they place larger units before smaller units or mix up the relative hierarchy.

5. An ISP advertises an enterprise broadband connection speed of 100 Mbps. What does the unit Mbps measure in network connectivity?

   • A. Processor clock frequency
   • B. Data transfer speed in megabits per second
   • C. Total disk storage capacity
   • D. Monitor display resolution
   Show answer

   Correct: B. Mbps stands for megabits per second, which measures network data transfer speed or throughput. Processor clock frequency, total disk storage capacity, and monitor display resolution are incorrect because processor clock uses hertz, storage uses gigabytes/terabytes, and display uses pixels.
