3 0

Answer:

First we understand what is hash function.A hash function is mostly used in Hashmaps. It maps different keys to a set of values.There may occur a case when we have same key but different values.This case is called collision.So we have to use different collision handling techniques that are open addressing and separate chaining.

A perfect hash function maps key-value pair such that there are no collisions.

What two statements about IPv6 addresses are true? This task contains the radio buttons and checkboxes for options. The shortcut
Oliga [24]

Answer:

A and C

Explanation:

Option A:

In IPv6 there is a rule to reduce an IPv6 address when there are two or more consecutive segments of zeros just one time. This rule says that you can change the consecutive zeros for “::”  

Here is an example

How to reduce the following IPv6 address?

ff02:0000:0000:0000:0000:0000:0000:d500

Ans: ff02::d500

Example 2:

2001:ed02:0000:0000:cf14:0000:0000:de95

Incorrect Answer -> 2001:ed02::cf14::de95  

Since the rule says that you can apply “::” just one time, you need to do it for a per of zero segments, so the correct answer is:

Correct Answer -> 2001:ed02::cf14:0:0:de95

Or

2001:ed02:0:0:cf14::de95

Option C:

Since in IPv6 there are 2^{128} available addresses which means 340.282.366.920.938.463.463.374.607.431.768.211.456 (too many addresses), there is no need of NAT solution, so each device can have its own IP address by the same interface to have access through the internet if needed. If not, you can block the access through internet by the firewall.

ASAP in the middle of this quiz Which of the following arguments might convince a local school board of the need to train upper
Arturiano [62]

Answer:

A.

Explanation:

Answer D seems too simplistic, and the question specifically mentions IT practices.

Question B doesn't seem right - college and high school students would likely be able to understand the principles as much.

Question C wouldn't be a good argument for a school board, and there's not a lot of evidence that backs it up.

Therefore, A seems to be the best choice here.

Hope this helps!
