Explanation

Buffer Pool Allocation: FALSE Statements Explained

C is false because SAP-ingress ports do not share a single buffer pool per MDA - each SAP-ingress port receives its own dedicated buffer pool, just like egress ports do. E is false because network ingress ports on the same MDA do not each get their own pool - they share one buffer pool across the entire MDA, which is the exact opposite of what E claims.

Why the distractors (A, B, D) are true:

• A - Network egress ports each get their own buffer pool.
• B - SAP-egress ports each get their own buffer pool.
• D - Network ingress ports on the same MDA share one pool. (This directly contradicts E, confirming E is false.)

The pattern to remember: Think "Egress = Exclusive, Network Ingress = MDA-wide shared." Both network and SAP egress get per-port pools. For ingress, only network ingress is shared per MDA - SAP ingress breaks the pattern and gets per-port pools. C and E are traps because C wrongly applies the "shared per MDA" rule to SAP-ingress, and E wrongly applies the "per-port" rule to network ingress.
