In Huawei's HWTACACS authentication scheme, which of the following packets are HTACACS accounting packets? (Multiple choice)

Question

Options

• AAccounting Reply
• BAccounting Response
• CAccounting Request
• DAccounting Start

• A
  15% (6)
• B
  78% (32)
• D
  7% (3)

Explanation

In HWTACACS, accounting uses a two-packet exchange: the NAS (client) sends an Accounting Request to the server, and the server replies with an Accounting Response - these are the two actual packet types defined in the HWTACACS accounting process, making B and C correct.

Option A (Accounting Reply) is wrong because "Reply" is the terminology used in standard TACACS+, not HWTACACS. Huawei's variant specifically uses "Response" - a key distinction that this question deliberately tests.

Option D (Accounting Start) is wrong because "Start" describes an accounting trigger/record type (Start, Stop, Real-time) that indicates when accounting occurs, not the name of a protocol packet itself.

Memory tip: Think of the pattern as a simple conversation - the NAS Requests, the server Responds. If you remember that HWTACACS uses "Response" (not TACACS+'s "Reply"), and that "Start/Stop" are event triggers rather than packet names, you'll avoid both traps.
