200-301 Question #1200: Real Exam Question with Answer & Explanation

Question

When deploying a new network that includes both Cisco and third-party network devices, which redundancy protocol avoids the interruption of network traffic if the default gateway router fails?

Options

• AVRRP
• BFHRP
• CGLBP
• DHSRP

Explanation

VRRP is the appropriate first-hop redundancy protocol for mixed-vendor networks because it is an open standard, ensuring interoperability between Cisco and third-party devices.

Common mistakes.

• B. FHRP (First Hop Redundancy Protocol) is a category, not a specific protocol, so it doesn't inherently guarantee cross-vendor compatibility.
• C. GLBP (Gateway Load Balancing Protocol) is a Cisco proprietary protocol and therefore would not be suitable for interoperability with third-party network devices.
• D. HSRP (Hot Standby Router Protocol) is a Cisco proprietary protocol, which limits its use in environments with non-Cisco network devices.

Concept tested. First Hop Redundancy Protocols (FHRP) compatibility
