When plugging the computer back into the network, the computer is unable to reach network resources. Which of the following is the most likely cause?
A DHCP server receives a request for an IP address from a device when it wants to connect to a network that uses the protocol.
What is DHCP and how does it work?Assigning IP addresses to stationary and mobile hosts that are wired or wirelessly linked is automated using DHCP, a covert process.
A DHCP server receives a request for an IP address from a device when it wants to connect to a network that uses the protocol.
When a device requests help, the server responds by sending an IP address to it. It then keeps track of how the address is being used and returns it after a set amount of time or when the device shuts down.
After that, the IP address is returned to the pool of addresses that the DHCP server manages so that it can be allocated to a different device when it requests network connectivity.
While assigning IP addresses is the protocol's primary role, DHCP also assigns a number of other networking-related settings, such as subnet mask, default gateway, and domain name server (DNS). BOOTP (bootstrap protocol), a predecessor to DHCP that can only be used on IPv4 networks, has been replaced by an IEEE standard called DHCP.

The array can be initialized as
1- An array can also be initialized during declaration. ( as in I )
2- In Initializing an array without assigning values, the default value of each element is zero. ( as in II )
3- An array can be initialized by setting each value of an element to zero by looping the length of the array. ( as in III)
I. It creates an array of 4 elements. The default value of int in java is Zero.
II. It also creates an array of 4 elements and manually initialized all the values to 0.
III. It creates an array of 4 elements. and uses a loop to manually initialized all the values to 0.
2) Output is 7 i.e Option(D).
total =total+values[total]; => total = 3+values[3];
=> total=3+(-2) => total=3-2 =>total=1.
total =total+values[total] =>total =1+values[1]
=>total= 1+6 =>total =7.
3)Option(D) i.e 2 8 10.
In If condition it is checking whether the element in the array is Positive and also it is divided by 2 with 0 reminder.
