Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 431

Which function does a Cisco SD-Access extended node perform?

Answer options

• A. provides fabric extension to nonfabric devices through remote registration and configuration
• B. performs tunneling between fabric and nonfabric devices to route traffic over unknown networks
• C. used to extend the fabric connecting to downstream nonfabric enabled Layer 2 switches
• D. in charge of establishing Layer 3 adjacencies with nonfabric unmanaged node

Correct answer: C

Explanation

The correct answer is C because the extended node is specifically designed to connect with downstream nonfabric enabled Layer 2 switches, extending the fabric. Option A is incorrect as it describes remote registration and configuration, which is not the primary function of an extended node. Option B mischaracterizes the role by emphasizing tunneling, which is not the main function. Option D is also incorrect since establishing Layer 3 adjacencies is not the primary responsibility of an extended node.
