Chapter 1 Review IPv4/IPv6 Addressing and Routing

How does a PC determine its network/subnet portion?

• By consulting its default gateway.

• By comparing its IP address to its subnet mask in binary.

• By performing an ARP request for the destination.

• By querying a DNS server.

In the DHCP for IPv4 DORA process, which message is sent by a client in an attempt to locate a DHCP server?

• DHCPOFFER

• DHCPREQUEST

• DHCPDISCOVER

• DHCPACK

When using EUI-64 to generate an IPv6 interface ID from a MAC address, what value is inserted into the middle of the MAC address?

• FFFF

• FFFE

• FEFF

• EFFF

For Stateless Address Autoconfiguration (SLAAC) to function correctly, what prefix length must the router interface advertising Router Advertisements (RAs) have?

• /32

• /48

• /64

• /128

Which of the following data structures is primarily used by a router's data plane for optimized packet forwarding?

• IP routing table

• ARP cache

• Forwarding Information Base (FIB)

• Control plane

Which of the following routing information sources has the lowest default administrative distance (AD)?

• OSPF

• EIGRP (internal)

• RIP

• eBGP

What is the default administrative distance (AD) of a static route?

• 0

• 1

• 90

• 110

Which of the following is true about IPv6 link-local addresses?

• They are routable globally.

• They are unique within an organization.

• They are used for communication only on the local link.

• They are assigned by a DHCPv6 server only.

What is the term for an IPv6 address that is globally routable and unique across the internet?

• Link-local address

• Site-local address

• Global unicast address

• Unique local address

What is the primary method for clients to obtain IPv6 addressing information using Stateless Address Autoconfiguration (SLAAC)?

• Requesting an address from a stateful DHCPv6 server.

• Dynamically assigning an address based on router advertisements.

• Manually configuring the IPv6 address on the host.

• Using DHCPv6 relay agents.
