Answer:
I will use the Omega network configuration if the economic factor is the determining one.
The total cost for the Omega network using the 4x4 switches will be $12,800, unlike the Butterfly network that can use the 16x16 switches that will cost $24,000.
Explanation:
The Omega network configuration will use the 4x4 switches which cost $50 each.  The total number of switches required = 4,096/16 = 256.  The total cost for 4x4 switches = 256 * $50 = $12,800.  This is better than the Butterfly network configuration that can use the 16x16 switch, costing $1,500 x 16 (4,096/256) = $24,000.
 
        
             
        
        
        
Answer:
Option C.
Explanation:
From the options given above, the correct way a renter can reduce their rent it to get a roommate or roommate. Getting just one roommate can help to reduce your basic living expenses by 30%.
This is achievable because various costs like rent, utilities, and even groceries can be shared among the roommates. 
The only downside to this method is the lack of privacy that comes with having roommates. But in general, having roommates is a sure way for renters to spend less, or live in a nicer location.
