Answer:
The answer is B: Differences in operating systems between the NSM server and other servers
Explanation:
All the evils on your network can be conquered effectively with the proper use NSM. NSM data equips CIRTs to detect and respond to cyber- attacks. With NSM, security analysts are able to discover intrusions early on in the process. Having highlighted all these positives, NSM encounters difficulties when faced with all of the above options apart from B.
Answer: True. Its true and it will be true.
Answer:
B. Missing helper addresses
Explanation:
The Dynamic Host Configuration Protocol serves the purpose of issuing the Internet protocol address mostly to machines sharing the same subnet. When hosted on another subnet, most routers would not allow DHCP to receive broadcast messages and respond to them. A helper address is used to broadcast network traffic outside their own local subnet.
So, the problem Jeff encounters is as a result of missing helper addresses that would have been useful in sending broadcast network traffic outside their subnet, to a DHCP in another server, which would then issue IP addresses to the client.
The switch statement is an n-way branch. An n-way branch can branch to any of an arbitrary number ( n ) of branches. An if statement can branch two ways, whether the condition is true or false.
The example you gave is a great example of how how code is written can make the code make sense or not.
public void setQuiz( int quiz, int grade )
{
switch( quiz )
{
case 1: // if quiz == 1
grade1 = grade; //where was grade1 declared?
break; // otherwise execution will continue through the next case block
case 2: // if quiz == 2
grade2 = grade;
break;
}
}
The variable named in the switch statement is tested against each case statement and whichever case statement's value matches, the rest of the switch statement's code is executed. (That's why the break statements are needed) Usually switch statements are written with a default case at the end as a "catchall".
