Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 323

Which feature is used to propagate ARP, broadcast, and link-local frames across a Cisco SD-Access fabric to address connectivity needs for silent hosts that require reception of traffic to start communicating?

Answer options

• A. Multisite Fabric
• B. Native Fabric Multicast
• C. SDA Transit
• D. Layer 2 Flooding

Correct answer: D

Explanation

Layer 2 Flooding is the correct answer as it enables the transmission of broadcast and link-local frames to all devices in the network, allowing silent hosts to receive necessary traffic. The other options, such as Multisite Fabric, Native Fabric Multicast, and SDA Transit, do not specifically address the propagation of these types of traffic required for silent hosts to initiate communication.
