Which statement describes standardization and vendor scope of HSRP and VRRP?

• A. HSRP is an open standard; VRRP is Cisco proprietary.
• B. VRRP is an open standard; HSRP is Cisco proprietary.
• C. Both are open standards.
• D. Neither supports preemption.

Answer: (B)

This tests understanding of which protocol is openly standardized and which is vendor-specific. VRRP was standardized by the IETF and published as an open standard (RFC 5798), so implementations from different vendors can interoperate. HSRP was created by Cisco and remains Cisco-proprietary, so it isn’t part of an open, vendor-independent standard. That’s why the correct statement is that VRRP is an open standard and HSRP is Cisco proprietary. The other choices misstate the standardization status (either claiming both are open standards or reversing who is open vs. proprietary). The preemption aspect is a separate configuration detail and doesn’t define the standardization scope here.
