   Which statement correctly compares HSRP and VRRP?

   • AHSRP supports load balancing among multiple routers, while VRRP does not
   • BHSRP uses a virtual MAC address, while VRRP uses the physical MAC address of the active router
   • CHSRP is an open standard, while VRRP is Cisco proprietary
   • DHSRP is Cisco proprietary, while VRRP is an open standard defined in RFC 5798

   In an FHRP implementation, hosts on a LAN are configured with a virtual IP address as their default gateway. How do the routers participating in the FHRP ensure that frames sent to the virtual IP are received by the active router?

   • AThe active router uses a virtual MAC address that is associated with the virtual IP address
   • BThe virtual IP is mapped to the MAC address of the router with the highest IP address
   • CThe routers broadcast all frames to the virtual IP to all hosts on the LAN
   • DEach router uses its own physical MAC address, and the hosts must be configured with that MAC address

   A service provider offers a managed router service to multiple customers. Each customer has their own VLAN and expects a redundant default gateway. The provider wants to use a single pair of routers to serve all customers, but must ensure that customer traffic is isolated and that each customer's gateway redundancy operates independently. Which approach is most appropriate?

   • AConfigure a separate HSRP group for each customer VLAN on subinterfaces, with unique virtual IPs and priorities.
   • BConfigure a single HSRP group on the shared interface and use access lists to isolate customer traffic.
   • CUse GLBP with a single group and rely on its load-balancing algorithm to separate customers.
   • DDeploy a separate pair of routers for each customer.

   A network administrator is designing a redundant gateway solution for a data center. The environment uses both Cisco and third-party routers. The administrator wants to use all available routers to forward traffic and also needs a standards-based solution for interoperability. Which combination of protocols should the administrator use?

   • AUse HSRP with multiple groups on the Cisco routers only.
   • BUse VRRP with a single virtual router and rely on the backup routers to forward traffic.
   • CUse VRRP with multiple virtual routers, one per router, and split hosts between them.
   • DUse GLBP on the Cisco routers and VRRP on the third-party routers.

   An engineer is configuring VRRP on two routers. The engineer wants to ensure that if the master router fails, the backup router takes over quickly. Which set of parameters should be tuned to achieve faster failover?

   • AIncrease the advertisement interval and increase the priority of the backup router.
   • BDecrease the priority of the master router and enable preemption on the backup router.
   • CIncrease the hold timer on the backup router and decrease the priority of the master router.
   • DDecrease the advertisement interval and decrease the master down interval.
