It provides a continuous network connection when a router fails.

router advertisements that are received from the link router

Which DHCPV6 verification command would display the link-local and GUA assigned address for each active client?

show ipv6 dhcp binding

What UDP port do DHCPV6 clients use to send DHCPV6 messages?

547

What flag settings combination is used for stateless DHCP?

A=1, M-0, O=1

What are the flag settings when a host should use the SLAAC only option?

A=1, M=0, O=0

What method is used by a host to verify an IPV6 address is unique on the local network before assigning that address to an interface?

DAD

Which destination IP address is used when an IPV6 host sends a DHCPV6 SOLICIT message to locate a DHCPV6 server?

FF02::1:2

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

HSRP does not provide load balancing with multipie active routers.

During which HSRP state does an interface begin sending periodic hello messages?

speak

What device is part of a virtual router group assigned the role of alternate default gateway?

standby router

What message informs IPV6 enabled i faces to use stateful DHCPv6 for obtaining an IPv6 address?

the ICMPV6 Router Advertisement

Which three DHCPV6 roles can a router perform? (Choose all that apply.)

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

1.) HSRP 2.) GLBP

Which FHRPS are Cisco-proprietary? (Choose two.)

1.) HSRP 2.) HSRP for IPV6

True or False? If a router with a higher HSRP priority joins the network, it will take over the active router roll from an existing active router which has a lower priority.

False

What are two characteristics of the SLAAC method for IPv6 address configuration? (Choose two.)

1.) IPV6 addressing is dynamically assigned to clients through the use of ICMPV6. 2.) The default gateway of an IPV6 client on a LAN will be the link-local address of the router interface to the LAN.

6. 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.)
