Hello,

I have 4 Local Queues (4MB msg length, max depth 10.000, non persistent)
I have 4 remote queues and the xmitq have (4MB msg length, max depth 10.000, persistent)

How can I calculate how much space I need?

is it 4 x 4MB x 10.000
+ 4 x 4MB x 10.000
+ 1x 4MB x DEAD LETTER QUEUE max depth ?

Location: US: west coast, almost. Otherwise, enroute.

Is this a certification test question?

No, for several reasons.
You will also find that this calculation will result in far more disk space that what could be provisioned. Doing this for a production system might require many peta bytes.
