Ou work for a large software company in seattle. they have their production environment provisioned on aws inside a custom vpc. the vpc contains both a public and private subnet. the company tests their applications on custom ec2 instances inside a private subnet. there are approximately 500 instances, and they communicate to the outside world via a proxy server. at 3am every night, the ec2 instances pull down os updates, which are usually 150mb or so. they then apply these updates and reboot: if the software has not downloaded within half an hour, then the update will attempt to download the following day. you notice that a number of ec2 instances are continually failing to download the updates in the allotted time. which of the following answers might explain this failure?

Write a program that begins by reading in a series of positive integers on a single line of input and then computes and prints the product of those integers. integers are accepted and multiplied until the user enters an integer less than 1. this final number is not part of the product. then, the program prints the product. if the first entered number is negative or 0, the program must print “bad input.” and terminate immediately. next, the program determines and prints the prime factorization of the product, listing the factors in increasing order. if a prime number is not a factor of the product, then it

File account.java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
