) What is the value of IPv6 address 2001:CA7F:5:2E:0:14 in binary? Your answer should consist of 128 bit values, each 0 or 1. 2. (5 points) My office computer is connected to an Ethernet LAN that supports IPv6. The MAC address of my Ethernet interface is 00-E5-93-FF-24-AB. What is the EUI-64 Link- Local IPv6 address for my Ethernet interface, which is determined by this MAC address? 3. (5 points) My desktop computer only supports IPv6 (not IPv4). I'm trying to send a packet to server "ancient website.com", which has IPv4 address 140.26.12.72 and has no IPv6 address. When I send a DNS request asking for the IPv6 address (AAAA record) for "ancient website.com" to a DNS64 server, what IPv6 address does it return to me? Assume standard NAT64 prefix of 64:ff9b::/64. 4. When an IPv6 device with no pre-configured IPv6 address powers up, it can calculate a global 128-bit IPv6 address for itself using Stateless Address Autoconfiguration (SLAAC), which combines two values: (a) a 64-bit IPv6 Prefix for the subnet (link) and (b) a 64-bit Interface ID. a) (5 points) How does the device learn the value of the IPv6 Prefix for its subnet? b) (5 points) How does the device determine the value of its Interface ID? Describe 2 ways. 5. (5 points) What is the difference between the "Pipe Model" and "Short Pipe Model" for MPLS DiffServ QoS Tunneling? 6. (5 points) What is the result of executing no mpls ip propagate-ttl? Why would a network administrator use this configuration? 7. Below is shown a portion of the BGP Table in router X. This router has discovered three different paths to destination network 150.88.0.0/16 in AS 1605. For each path, the BGP Table shows the Next Hop address for the next BGP router along this path towards that destination network, as well as 4 Path Attributes, which are "Metric", "Local Preference", "Weight" and "AS Path".

If so, which BGP routers? b) (5 points) Given the values shown, which one of these three routes will router X select to copy into its routing table for destination 150.88.0.0/16? Why? c) (5 points) Suppose the route you chose in answer (b) goes down, then which of the remaining two routes will router X select to copy into its routing table for destination 150.88.0.0/16?
