Ultimate Quiz On CCENT/CCNA Icnd2 Chapt. 16 + 17

CIDR stands for Classless Interdomain Routing. CIDR is a method used to allocate and manage IP addresses more efficiently. It allows for the aggregation of multiple IP addresses into a single routing prefix, reducing the size of routing tables and improving the scalability of the internet. Unlike classful IP addressing, which divides IP addresses into fixed classes, CIDR allows for more flexible allocation of IP addresses, making it more suitable for the modern internet.

The last line mentions that the pool has seven addresses, with all seven allocated, with the misses counter close to 1000—meaning that close to 1000 new flows were rejected because of insufficient space in the NAT pool.

Inside a quartet, any leading 0s can be omitted, and one sequence of 1 or more quartets of all 0s can be replaced with double colons (::). The correct answer replaces the longer 3-quartet sequence of 0s with ::.

One method for IPv6 global unicast address assignment is that ICANN allocates large address blocks to RIRs, RIRs assign smaller address blocks to ISPs, and ISPs assign even smaller address blocks to their customers.

Global unicast addresses begin with 2000::/3, meaning that the first 3 bits match the value in hex 2000. Similarly, unique local addresses match FD00::/8, and link local
addresses match FE80::/10 (values that begin with FE8, FE9, FEA, and FED hex). Multicast IPv6 addresses begin with FF00::/8, meaning that the first 2 hex digits are F.

RFC 1918 identifies private network numbers. It includes Class A network 10.0.0.0, Class B networks 172.16.0.0 through 172.31.0.0, and Class C networks 192.168.0.0 through 192.168.255.0.

OSPFv3, RIPng, EIGRP for IPv6, and MP-BGP4 all support IPv6.

With static NAT, the entries are statically configured. Because the question mentions translation for inside addresses, the inside keyword is needed in the command.

With dynamic NAT, the entries are created as a result of the first packet flow from the inside network.

CIDR’s original intent was to allow the summarization of multiple Class A, B, and C networks to reduce the size of Internet routing tables. Of the answers, only 200.1.0.0
255.255.0.0 summarizes multiple networks.

The list 1 parameter references an IP ACL, which matches packets, identifying the inside local addresses.

RIPng configuration does not use a network command; instead, the ipv6 rip command is configured on the interface, listing the same tag as on the ipv6 router rip command, and the enable keyword.

Network Address Translation–Protocol Translation (NAT-PT) translates between IPv4 and IPv6, and vice versa. The two tunneling methods allow IPv6 hosts to communicate with other IPv6 hosts, sending the packets through an IPv4 network. Dual-stack allows a host or router to concurrently support both protocols.

When translating inside addresses, the outside address is not translated, so the outside local address does not need to be identified in the configuration.

The configuration is missing the overload keyword in the ip nat inside source command and in the ip nat outside interface subcommand on the serial interface.

IPv6 supports stateful DHCP, which works similarly to IPv4’s DHCP protocol to dynamically assign the entire IP address. Stateless autoconfiguration also allows the assignment by finding the prefix from some nearby router and calculating the interface ID using the EUI-64 format.

The configuration explicitly assigns the 3456::1 IP address. The interface also forms the EUI-64 interface ID (6444:44FF:FE44:4444), adding it to FE80::/64, to form the link local IP address.

Stateless autoconfiguration only helps a host learn and form its own IP address, but it does not help the host learn a default gateway. Stateless RS is not a valid term or feature. Neighbor Discovery Protocol (NDP) is used for several purposes, including the same purpose as ARP in IPv4, and for learning configuration parameters like a default gateway IP address.
