A complete binary tree with N nodes may be stored in an array A of length N by storing the root at A[0], and then storing in successive array locations the nodes of the tree in increasing order of the level of nodes. If nodes in the same level are stored in left to right order, then the node stored at A[k] will be a leaf if and only if
A) 2k+1 ? N B) 2k+1 > N C) k/2 > N D) None of the above
Your job is to examine the access lists to see whether they meet the stated goals. You are to make corrections to the configurations as needed. The trouble ticket for this is shown as follows. Investigate the access list configurations, make corrections or modifications to the network as necessary, and report your findings. Use access list 1 for standard and 101 for extended when numbering your access lists.
The objective of this exercise is to verify that the access lists provided on Routers R1, R2, R3, and
R4 have been properly configured to meet the following stated goals.
Access list goals:
? Only HTML traffic can access the web server through the 192.168.2.2 interface on Router R2.
The rest of the server subnet has no restrictions.
? Only the Finance department subnet (192.168.1.0) can access the financial database subnet.
? The Lobby Kiosk PC, connected to the Fa0/0 interface on Router R3, can only access the web
server; the rest of the kiosk subnet (192.168.3.0) has no restrictions.
