Answer:
Gaining Access Phase
Explanation:
Before the hacker gets to the maintaining access phase, two phases are already passed, these phases are:
<em>1. Reconnaissance</em> - Gathering all necessary information for the attack.
<em>2. Scanning</em> - using tools such as vulnerability scanners, network mappers, dialers among others to analyze the network using information gotten from the Reconnaissance phase.
Once the vulnerabilities of the system are discovered in the first two phases, the hacker is actively attacking the system in the third phase.
<em>3. Gaining Access</em> - At this phase, the hacker carries out the attack from the information retrieved from Phase 1 and 2. The system vulnerabilities already discovered are exploited efficiently to own the system. This can be carried out offline, through the internet, by having access to the host computer or through wired or wireless LAN.
Two phases come after the "gaining access" phase. They are:
<em> 4. Maintaining access</em> - At this phase, the hacker secures his access to the system from security personnel or other hackers. They ensure that backdoors are established to gain quick and easy access to the system for further attacks.
<em> 5. Covering Tracks</em> - log files are removed or modified by hackers to ensure that their actions are completely invisible to any suspecting person.
Answer:
A circular network happens when you have two (or more) routes to the same controller. Typically, the routes are BACnet/IP and BACnet/Ethernet and both are communicating on both networks. This could happen with BACnet MS/TP although it is rare.

Answer:
The error in the given question is that the class xyz must be abstract i.e
abstract class xyz.
Explanation:
In the given code the class xyz contain abstact method so class xyz must be abstract because abstract class contain abstract method .Abstract class contain final variable and abstract method by default all the method in abstract class is abstract and variable are final .
Syntax:
abstract class classname
{
//final variable
// abstract method
// method
}
so coorect code is
abstract class XYZ
{ public static final int A = 9;
public abstract void foo1( );
public int foo2( )
{
return 5;
}
}
