Entities such as GK, MCU, and Terminal are defined in the H.323 communication protocol suite. The MCU is used for address translation and access control,

Question

Options

• ATRUE
• BFALSE

• A
  29% (9)
• B
  71% (22)

Explanation

B is correct because the statement misattributes the roles - it is the Gatekeeper (GK), not the MCU, that handles address translation (mapping aliases to IP addresses) and access control (admission and bandwidth management) in H.323.

Option A is wrong because accepting the statement as true would mean confusing two distinct H.323 components with entirely different functions - the MCU's actual role is managing multipoint conferences, allowing multiple endpoints to participate in a single call.

The distractor works by listing real H.323 entities (GK, MCU, Terminal) correctly, then sneaking in a false function assignment, hoping you'll focus on the entities rather than scrutinizing which entity does what.

Memory tip: Think of GK = Gatekeeper = bouncer at the gate - a bouncer checks IDs (access control) and directs people to the right room (address translation). The MCU = Meeting Control Unit - it runs the meeting when many people join at once.
