These visible examples show the question style. LearnClash turns the full topic into ranked duels and spaced repetition.

What OSI layer sends raw bits across cables?
Answer: Physical
Why: The Physical layer works directly with hardware, translating binary digits into electric pulses or radio signals.
-
What is the standard maximum payload for an Ethernet frame?
Answer: 1500 bytes
Why: Standard Ethernet limits payloads to 1500 bytes, though jumbo frames can carry up to 9000 bytes.
-
Where are dialogue checkpoints set in OSI?
Answer: Session
Why: Session layer checkpoints save transmission progress so dropped links can resume from the last point.
-
How many bits make up an IPv4 address at OSI Layer 3?
Answer: 32
Why: Those 32 bits yield around 4.3 billion addresses, which eventually led to IPv6 and its 128-bit address space.
-
What is data called at the Transport layer of OSI?
Answer: Segment
Why: Data changes its unit label at each layer: segments at Layer 4 become packets, then frames, then bits.
-
Which OSI directory standard formed the basis for LDAP?
Answer: X.500
Why: LDAP was created because the original X.500 directory protocol required the full OSI stack instead of running directly over TCP/IP.
