Briefly define the $3$ key technical goals in network design. Use the format below:

Technical goal $1($specify$)$: Definition $(2$ lines MAX$)$

Technical goal $2($specify$)$: Definition $(2$ lines MAX$)$

Technical goal $3($specify$)$: Definition $(2$ lines MAX$)$

For each technical goal above, discuss four $(4)$ best practices $^(3)$ in network design one can use to

reach that goal. Do not use a same best practice more than once in this exercise, which means

you should discuss a total of $12$ different $^(4)$ best practices. Use the format below:

Best practice # $1$ for technical goal $1(10$ words MAX$)$

Explain how your best practice # $1$ improves technical goal $1(3$ lines MAX$)$

IF this is not a default best practice, briefly explain when it is recommended $(2$ lines MAX$)$

Best practice # $2$ for technical goal $1(10$ words MAX$)$

Explain how your best practice # $2$ improves technical goal $1(3$ lines MAX$)$

IF this is not a default best practice, briefly explain when it is recommended $(2$ lines MAX$)$

Best practice #$3$ for technical goal $1(10$ words MAX$)$

Explain how your best practice # $3$ improves technical goal $1(3$ lines MAX$)$

IF this is not a default best practice, briefly explain when it is recommended $(2$ lines MAX$)$

Best practice #$4$ for technical goal $1(10$ words MAX$)$

Explain how your best practice # $4$ improves technical goal $1(3$ lines MAX$)$

IF this is not a default best practice, briefly explain when it is recommended $(2$ lines MAX$)$

Best practice #$5$ for technical goal $2(10$ words MAX$)$

Explain how your best practice # $5$ improves technical goal $2(3$ lines MAX$)$

IF this is not a default best practice, briefly explain when it is recommended $(2$ lines MAX$)$

Etc.

Use the Key technical goals$($ Availability, Response time $($or throughput$),$ and Scalability only
