What neighbor data should be stored on a host?
What will be an ideal response?
For each active network interface, a node needs to store all the following information:
Neighbor cache-A table of information containing the on-link address for each neighbor. It may include the link-layer address, the neighbor's state of reachability, and whether the neighbor is a host or a router.
Destination cache-A table of information containing data about destinations to which traffic has been sent, including both on-link and off-link nodes. The destination IPv6 address is mapped to the next-hop address of the neighbor. Data not related to ND may also be stored in the destination cache, such as the PMTU and round-trip timers. This list may also be updated from Redirect messages.
Prefix list-A table of information containing data from Router Advertisement messages of the on-link prefix addresses. In addition, each entry has an invalidation timer so it can expire prefixes as they become invalid. Link-local prefixes have an infinite invalidation timer regardless of whether a Router Advertisement message is received for the link-local prefix or not.
Default router list-This contains IP addresses of routers that have sent Router Advertisement messages. Each entry also includes its invalidation timer value.

Which of the following will check to see if a password contains a # sign, given that the character code for "#" is 37? The password is 8 characters long and is stored in a variable named pword.
a. ``` var check = false; for (j = 1; j < 7; j++) { if (pword.charCodeAt[j] == 37); check = true; } ``` b. ``` var check = false; for (j = 0; j < 8; j++) { if (pword.charCodeAt(j) == 37) check = true; } ``` c. ``` var check = false; for (j = 0; j <= 8; j++) { if (pword.charCodeAt()== 37) check = true; } ``` d. ``` var check = true; for (j = 1; j < 9; j++) { if (pword.charCodeAt(37)== "#") check = true; } ```
