What is the default method for determining the interface ID for a link-local address on Ethernet?
EUI-64
MAC address with FFFE at the end

Which of the following routing protocols have both an IPv4 and IPv6 version? (Choose all that apply.)
Routing Information Protocol
Enhanced Interior Gateway Routing Protocol
Open Shortest Path First
Interior Gateway Routing Protocol
Which best practices apply to networks that run both IPv4 and IPv6? (Choose all that apply.)
Physical security
Routing protocol authentication
Authorization of administrators
Written security policy
Which of protocols, if abused, could impair an IPv6 network, but not IPv4? (Choose all that apply.)
ARP
NDP
Broadcast addresses
Solicited node multicast addresses
If a rogue IPv6 router is allowed on the network, which information could be incor- rectly delivered to the clients on that network? (Choose all that apply.)
IPv6 default gateway
IPv6 DNS server
IPv6 network address
IPv6 ARP mappings
Why is tunneling any protocol (including IPv6) through another protocol a security risk?
The innermost contents of the original packets may be hidden from normal security filters.
The tunnels, if they extend beyond the network perimeter, may allow undesired traffic through the tunnel.
Functionality might need to be sacrificed when going through a tunnel.
Quality of service, for the underlying protocol, might be compromised.
What is one method to protect against a rogue IPv6 router?
Port security
Static ARP entries
DHCPv6
RA guard
