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.

The answer is A, or Locating bottlenecks in a network.
Answer:
#include <stdio.h>
int main()
{
int userNum1;
int userNum2;
userNum1 = -1;
userNum2 = 7;
if (userNum1 < 0)
printf("userNum1 is negative. \n");
if(userNum2 > 9)
userNum2 = 0;
else
printf("userNum2 is less than or equal to 9.\n");
return 0;
}
Explanation:
Initialize userNum1 and userNum2.
If userNum1 is less than 0, print 'userNum1 is negative" and end with newline.
if userNum2 is greater than 9, assign 0 to userNum2.
Otherwise, print "userNum2 is less than or equal to 9 and end with newline.
