What is the purpose of the destination address selection algorithm?
What will be an ideal response?
The purpose of the destination address selection algorithm is to sort through the list of possible IPv4 and IPv6 destination addresses and order them from highest to lowest preference. IPv4 destination addresses are expressed as IPv4 mapped addresses so that the algorithm can locate the attributes of the IPv4 address in the policy table. IPv4 mapped addresses are expressed in the format ::ffff:w.x.y.z and are scoped as follows:
* Public IPv4 addresses are scoped as global.
* Automatic Private IP Addressing (APIPA) addresses are scoped as link-local.
The algorithm takes the list of destination addresses, sorts them, and generates a new list expressed as a pairwise comparison wherein (for our purposes) address Dest1 appeared in the original list before Dest2. Source(D) indicates a chosen source address for a specific destination (D).

A table has 100,000 rows and each row occupies 200 bytes. The table is stored on a disk which has 4k bytes per page. Compute the maximum (worst case) cost (number of I/O operations) of doing an equality search on the primary key assuming the following access paths. Make your reasoning clear - a number without an explanation gets no credit.
(a) The data file is unsorted and has no index. (b) The data file is sorted on the primary key and has no index. (c) There is an unclustered static hash index whose search key is the primary key. Assume all buckets are stored on disk and that each bucket has one overflow page. (d) There is an unclustered B+ tree index whose search key is the primary key. Assume that each entry in the tree occupies 20 bytes and the entire tree resides on the disk.
