True or False? A virtual LAN (VLAN) provides the ability to segregate network traffic and increase performance.

All of the following are true about traditional wide area networks (WANs), except:

Devaki is a network consultant. She is helping a client upgrade its aging network infrastructure. When designing elements of the network, what can she do to prevent broadcast storms and provide for a redundant network connection in the event of physical cable or switch failure?

All of the following are true of network access control (NAC), except:

Arturo is expanding workgroup LANs into departmental LANs. What will dictate the best topology for each LAN?

All of the following are true of Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), except:

All of the following are common network resiliency methods, except:

Programming Final 100 points. In this final, you will be manipulating a grid. You may assume the user will enter correct input (unless noted). Read data that makes up a grid from a file The file must be named test.txt First two numbers in the file are the sizes of grid. The first number is the X size (so how many spots across), the second value is the Y size (how many spots down). After the sizes, the rest of the file is filled with data to fill in the grid. Example file: 3 4X Y YA B CD E FH F A Print out the contents in a grid. For the example file, the output should be X Y YA B CD E FH F A NOTE: Your array might be transposed once you print out the data. If you cannot figure it out quickly why that is, continue on and come back. A transposed print is worth a lot less than the rest of the exam. Repeatedly loop over a menu. Options in the menu: Update all the values in a row with a particular value The user enters in the row number and a value and all entries in that row are set to the value. Query a value if given the indexes. Here the user inputs an X and Y and you print out the value present at the spot. You must account for if the user does not enter a valid X or valid Y – send the user back to the menu if it is invalid. Print the grid. Print out whether a particular value is in the grid Here the user enters in a VALUE and you tell them if it exists in the grid. If anything else is entered then the program exits.

According to the following reaction, what amount of Al2S3 remains when 20.00 g of Al2S3 and 2.00 g of H2O are reacted? Molar Masses: Al2S3 = 150.17 g/mol, H2O = 18.02 g/mol.

Which response includes only species that have the electronic configuration 1s2 2s2 2p6 3s2 3p6, and no other species?
