Answer: (B) Issue an alter system switch logfile command.
Explanation:
When the database is in the archive log mode then, the issue in the alter system switch logfile command force the particular switch. It basically produce achieve redo log which is smaller in the size by the dedicated size of the parameter log buffer.
It also govern the particular size of the RAM (Random access memory) buffer by redo log. This command is basically faster to return in the program by the use of redo log.
On the other hand, all the options are incorrect as this command only alter the system and does not alter the database. Therefore, Option (B) is correct.
Answer:
class Example:
def __init__(self, val):
self.val = val
def __gt__(self, other):
return self.val > other.val
def __sub__(self,other):
return abs(len(self.val) - len(other.val))
def main():
obj1 = Example('this is a string')
obj2 = Example('this is another one')
print(obj1 > obj2)
print(obj1 - obj2)
main()

Answer:
The answer is below
Explanation:
The various stages in the information processing cycle in the correct order is as follows:
1. Input stage: this is when the data is sent into the computer through the hardware
2. Processing stage: this when the is being refined in the central processing unit of the computer
3. Storage stage: this is when the data is being saved or stored in the computer memory such as Hard drive or external storage such as Flash drive
4. Output stage: this is when the refined or processed data is produced to the user either through the monitor screen or printing
Answer:
enable the used ports in the router with their respective IP address and only the connected ports in the switch. Allow configure the STP on the switch
Explanation:
Network switches are used to connect a group of computer devices in a network LAN. It is automatically enabled when a port is connected and creates a MAC address table of the computers connected to it. STP or spanning-tree protocol is a protocol used to prevent looping in a switch. Unused ports can be disabled for security reasons.
A router is a network device that is used to forward packets between networks. All used ports in a router must be enabled and configured with an IP address and subnet mask.
Answer:
By saving it in the hard drive.
