Question

Which Cisco product supports SD-Access and specifically built to address new challenges faced by enterprises?

Options

• BASR 1000-HX
• CCatalyst 6807-XL w/ Sup6T and C6800 10G line cards
• DCatalyst 9500
• EISR 4221
• FNexus 7700 w/ Sup2E and M3 line cards

Explanation

The Cisco Catalyst 9500 series switches are specifically designed to support Cisco SD-Access, offering high performance, security, and programmability required for modern enterprise networks. These switches serve as core and distribution layer devices within an SD-Access fabric.

Common mistakes.

• A. CSRv (Cloud Services Router 1000V) is a virtual router primarily used for WAN and cloud connectivity, not as a core component of an SD-Access campus fabric.
• B. ASR 1000-HX series routers are primarily designed for enterprise WAN aggregation and edge services, not as the primary switch platform for SD-Access campus fabric.
• C. The Catalyst 6800 series are older generation modular switches, and while powerful, they are not specifically built for or optimized for SD-Access in the way the Catalyst 9000 series is.
• E. ISR 4221 series routers are entry-level integrated services routers used for branch offices, not for the core or distribution layers of an SD-Access campus network.
• F. Nexus 7700 series switches are data center switches, optimized for data center fabrics, not for enterprise campus SD-Access deployments.

Concept tested. Cisco SD-Access compatible hardware (Catalyst 9000 series)
