In what scenarios is the following used:

SONA - Service Orientated Network Architecture layers are, Application, Interactive Services, & Network Infrastructure - Im thinking Media type businesses ie TV?

Core, Dist, Access - Are heirarchical layers used for maybe some small or corporations type maybe dependant on design requirements etc.

Core, Aggregation & Access - Used in Datacentres.  Is LACP & PAGP used in this situation only

>SONA
All the layers do not have to be used, remember, the SONA is just a framework; a senario woud be that of a call center that need to upgrade its phone system:

Requirements: IP and must support the integration of their existing IP Network

The Cisco Unified Communications deployment in that you could use the Cisco SONA framework to simply the deployment in a layered fashion. Some examples: Cisco Unified CallManager, Cisco Unified IP Phones, Cisco IP Communicator, network security, and QoS technologies built upon a Cisco's converged IP network leading to a centralized call processing that supports new applications.

>Core, Dist, Access - Are heirarchical layers used for maybe some small or corporations type maybe dependant on design requirements etc.

This is an old design; however, it is still used in many networks today ranging from Enterprises to Small businesses; There is a concept call collapsed Core, Distribution, and Access in that you collapse a layer onto one another to form one or two layers to be cost effective and also still allows you to scale to a 3 layer if designed properly. You might see a 3 layer design (Non-collapsed) with companies such as NetFlix, Webhosting companies, and very small ISPs and Data Centers:

>Core, Aggregation & Access - Used in Datacentres.  Is LACP & PAGP used in this situation only
LACP and PAGP is used in any situation that requires the aggregation of links to increase reliablity and bandwidth. Typically between the access layer and the agg layer, PaGP/LACP is used; however, in most designs today, 10Gbps links are used with the concept of VSS; this is the stuff that dreams are made out of!
