CCNA2 MODULE 9

What is the purpose of HSRP?

• It prevents a rogue switch from becoming the STP root

• • It provides a continuous network connection when a router fails.

• • It enables an access port to immediately transition to the forwarding state.

• • It prevents malicious hosts from connecting to trunk ports.

Which nonproprietary protocol provides router redundancy for a group of routers which support IPv4 LANs?

• • SLB

• • HSRP

• • VRRPv2

• • GLBP

A network administrator is analyzing first-hop router redundancy protocols. What is a characteristic of VRRPv3?

• • It works together with HSRP

• • It allows load balancing between routers

• • VRRPv3 is Cisco proprietary

• • It supports IPv6 and IPv4 addressing

What is a potential disadvantage when implementing HSRP as compared to GLBP?

• • HSRP provides default gateway failover only when the active router fails

• • HSRP does not function in a multivendor environment

• • HSRP does not provide load balancing with multiple active routers

• • HSRP does not have the capability to support IPv6 addresses.

A network engineer is configuring a LAN with a redundant first hop to make better use of the available network resources. Which protocol should the engineer implement?

• • HSRP

• • GLBP

• • VRRPFHRP

When first hop redundancy protocols are used, which two items will be shared by a set of routers that are presenting the illusion of being a single router? (Choose two.)

• • IP address

• • BID

• • hostname

• • MAC address

• • static route

In FHRP terminology, what represents a set of routers that present the illusion of a single router to hosts?

• • virtual router

  
  

• • default gateway

  
  

• • forwarding router

• • standby router

A user needs to add redundancy to the routers in a company. What are the three options the user can use? (Choose three.)

• • HSRP

• • VRRP

• • STP

• • GLBP

• • IPFIX

Which two protocols provide gateway redundancy at Layer 3? (Choose two.)

• • HSRP

• • PVST

• • STP

• • VRRP

• • RSTP

A network administrator is overseeing the implementation of first hop redundancy protocols. Which two protocols are Cisco proprietary? (Choose two.)

• • IRDP

• • GLBP

  
  

• • VRRP

• • VRRPv2

• • HSRP
