If the desire is to connect virtual network functions together to accommodate different types of...

In modern network architectures, particularly those using NFV (Network Function Virtualization),Service Chainingis used to direct traffic through a sequence of virtualized network functions (VNFs)—such as firewalls, load balancers, NAT devices, etc.—based on service requirements.

Service chaining allows:

Dynamic or policy-based redirection of traffic through VNFs

Simplified orchestration of network services

Scalability and flexibility across multi-tenant or virtualized environments

CCDE v3.1 emphasizes service chaining as a key enabler in cloud-native and virtualized architectures, ensuring services are efficiently composed based on application or security needs.

Why other options are incorrect:

A and E (Bridging/Switching): Refer to traditional Layer 2 forwarding and do not provide VNF sequencing logic.

C and D: “Linking” and “Daisy chaining” are not standard or scalable methods in NFV environments.
