Oxnard Casualty wants to ensure that their e-mail server has 99.98 percent reliability. They will use several independent server

sattari [20]

Answer:

The smallest number of servers required is 3 servers

Explanation:

Given

$Reliability = 99.98\%$

$Individual Servers = 95\%$

Required

Minimum number of servers needed

Let p represent the probability that a server is reliable and the probability that it wont be reliable be represented with q

Such that

$p = 95\%\\$

It should be noted that probabilities always add up to 1;

So,

$p + q = 1$ '

Subtract p from both sides

$p - p + q = 1 - p$

$q = 1 - p$

Substitute $p = 95\%\\$

$q = 1 - 95\%$

Convert % to fraction

$q = 1 - \frac{95}{100}$

Convert fraction to decimal

$q = 1 - 0.95$

$q = 0.05$

------------------------------------------------------------------------------------------------

To get an expression for one server

The probabilities of 1 servers having 99.98% reliability is as follows;

$p = 99.98\%$

Recall that probabilities always add up to 1;

So,

$p + q = 1$

Subtract q from both sides

$p + q - q = 1 - q$

$p = 1 - q$

So,

$p = 1 - q = 99.98\%$

$1 - q = 99.98\%$

Let the number of servers be represented with n

The above expression becomes

$1 - q^n = 99.98\%$

Convert percent to fraction

$1 - q^n = \frac{9998}{10000}$

Convert fraction to decimal

$1 - q^n = 0.9998$

Add $q^n$ to both sides

$1 - q^n + q^n= 0.9998 + q^n$

$1 = 0.9998 + q^n$

Subtract 0.9998 from both sides

$1 - 0.9998 = 0.9998 - 0.9998 + q^n$

$1 - 0.9998 = q^n$

$0.0002 = q^n$

Recall that $q = 0.05$

So, the expression becomes

$0.0002 = 0.05^n$

Take Log of both sides

$Log(0.0002) = Log(0.05^n)$

From laws of logarithm $Loga^b = bLoga$

So,

$Log(0.0002) = Log(0.05^n)$ becomes

$Log(0.0002) = nLog(0.05)$

Divide both sides by $Log0.05$

$\frac{Log(0.0002)}{Log(0.05)} = \frac{nLog(0.05)}{Log(0.05)}$

$\frac{Log(0.0002)}{Log(0.05)} = n$

$n = \frac{Log(0.0002)}{Log(0.05)}$

$n = \frac{-3.69897000434}{-1.30102999566}$

$n = 2.84310893421$

$n = 3 (Approximated)$

Hence, the smallest number of servers required is 3 servers

Fill in the blank. The process that a wireless router uses to translate a private IP address on internal traffic to a routable a

AleksandrR [38]

Answer:

Network Address Translation (NAT)

Explanation:

With the aid of Network address translation(NAT), the IP addresses of a particular local network are translated or mapped into a single or multiple global or public IP addresses. Therefore, a wireless router could use NAT to translate its private IP address on internal traffic (network) to a routable address for the internet.

With NAT, businesses can use many internal IP addresses since they are just for internal purposes and will be eventually converted into a single or a few multiple routable IP addresses.

Three types of NAT are possible:

(i) Static NAT : There is a one - to - one mapping between private IP addresses and routable (public) IP addresses. One private IP is mapped to one public IP address.

(ii) Dynamic NAT : There is a many- to - many mapping between private IP addresses and routable (public) IP addresses. Multiple private IPs are mapped to many public IP addresses.

(iii) Port Address Translation (PAT) : Many - to - one relationship between the private IP addresses and public addresses. Many private IP addresses can be mapped or translated into a single public IP address. This type of NAT is also called NAT overload.

Universal Containers has quotes that have multiple Quote Lines for the same Product. They require all Products with the Product

shusha [124]

Answer:

The field that is used to sum the fields that are relevant in the list and show in the main record is known as roll up field.

Explanation

The universal containers are used to contain all types of products information for the purpose of security and management of data.

It is required in the document that, we have to mention the quotes at different places along with their name. So, we use roll up field to manage the quotes of same product name at different lines of the document.
