Answer:
First two statements: yes. Last two: not so much.
But many of the better ones do have advanced degrees, but some don't.
The laboratory statement is silly; they sit behind a set of screens figuring out stuff and writing code.
Answer:
A. Define boundaries
C. Deny access
D. Delay access
Explanation:
A barrier is a material or structure used to prevent or block access. Barriers can either be natural or structural and are used for many purposes usually for security reasons. The following are functions of barriers either natural or structural:
- Define areas of boundaries
- Delay or slow access. Example is the use of speed bumps to slow down vehicles.
- Provide access to entrances such as the use of gates
- Deny access to unauthorized personnel and allowing authorized personnel.
if(Expression to be tested) {
code to execute
} else if(Expression to be tested) {
code to execute
}
you can have as many else ifs as you want. But that's what it looks like.
Answer:
Did you mean layer 3 switch? Because a router always operates at layer 3
Explanation:
If the answer is yes, then a layer 3 is a switch that combines the functions of a switch and a router. So it is capable of operate layer 2 and layer 3. Some of its benefits are: Support routing between VLAN, decrease network latency because the packets don’t have to make extra hops to go through a router and reduce security management. But they are really expensive and lack of WAN functionality so they are used mostly for large intranet environments.
Answer:
Here's some really bad code that works:
public static double average(int a, int b, int c, int d, int e)
{
return (((double)a + b + c + d + e) / 5);
}
