Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 648

Which technology provides an overlay fabric to connect remote locations utilizing commodity data paths and improves network performance, boosts security, and reduces costs?

Answer options

Correct answer: C

Explanation

SD-WAN is designed to create an overlay network that can connect multiple remote locations efficiently over existing internet connections, improving performance and security while reducing costs. InfiniBand is a high-speed network technology primarily used in data centers, VTEP is a component of VXLAN for encapsulating Layer 2 frames, and VXLAN is an overlay technology but does not specifically address the connectivity and optimization features provided by SD-WAN.
