It is common for people to name directories as dir1, dir2, and so on. When there are ten or more directories, the operating system displays them in dictionary order, as dir1, dir10, dir11, dir12, dir2, dir3, and so on. That is irritating, and it is easy to fix. Provide a comparator that compares strings that end in digit sequences in a way that makes sense to a human. First compare the part before the digit as strings, and then compare the numeric values of the digits.

Which of the given assertion methods will return true for the code given below? Student student1 = new Student(); Student student2 = new Student(); Student student3 = student1;
The Student class is as follows.
public class Student{
private String name;
}
a. assertEquals(student1, student2);
b. assertEquals(student1, student3);
c. assertSame(student 1, student3);
d. assertSame(student1, student2);
Answers
Answer:
The true statements are :
A. assertEquals(student1,student2)
C. assertSame(student1,student3)
Explanation:
AssertEquals() asserts that the objects are equal, but assertSame() asserts that the passed two objects refer to the same object or not, if found same they return true, else return false.
Methods are collections of named code segments that are executed when evoked
The assertion method that will return true for the given code is: assertEquals(student1,student2)
The code segment is given as:
Student student1 = new Student();
Student student2 = new Student();
Student student3 = student1;
In Java, the assertEquals() method returns true if two objects have equal values.
Assume student1 and student2 have equal values, the statement assertEquals(student1,student2) will return true

What’s cloud-based LinkedIn automation?

Cloud based LinkedIn automation includes tools and software that run through the cloud-system and are not detectable by LinkedIn. Cloud based LinkedIn automation tools are becoming the favorite among B2B marketers and sales professionals as they are giving the desired outcomes without any effort.
Scenarios are quite common where an IT professional is tasked with modify a file on many computer systems or many files on a single computer or a combination of the two. For example, a large software may need the copyright notice comment to be changed on every source file in the project. Or, a configuration file may need to be modified on every server in a multi-server deployment. Doing this task manually is not a viable way to approach the problem. Instead, a better solution is to use a scriptable environment to perform search and replace functionality on the files in question. Python is an excellent tool for this kind of task.
Description
Samba is a unix/linux file sharing suite of programs designed to provide Windows interoperable file and print sharing services. Much of the configuration for the Samba daemon is provided by the text file smb.conf (renamed to smb.txt for this assignment). After an update was deployed to three dozen linux servers it was discovered that a couple of configured parameters were incorrect. Unfortunately, since there are unique aspects to each server, copying the contents of a single file to each server is not a viable solution. To fix the problem, the IT department must connect to each server, edit the smb.conf file, and restart the smbd daemon. To automate this task, each server will have a Python script copied to it. Then an SSH session will be initiated to each server from which the script will be executed. Your task is to write the Python script.
The invocation of the script must be as follows:
python modify.py fileSpec "from" "to"
where,
modify.py is the name of your script
fileSpec is the name of the file to be modified (smb.txt)
"from" is the text to be searched for (be sure to enclose any white space in quotes.
"to" is the text the searched text is to be replaced with.
Testing the script is your responsibility. However a good test case is:
python modify.py smb.txt "password sync = yes" "password sync = no"
Answers
Answer:
Explanation:/
The example Python script that can be used to automate the modification of the smb.conf file on multiple Linux servers is shown below
What is the code?python
import subprocess
import sys
def modify_smb_conf(file_spec, search_text, replace_text):
try:
# Open the file for reading
with open(file_spec, 'r') as file:
# Read the contents of the file
file_contents = file.read()
# Perform the search and replace operation
modified_contents = file_contents.replace(search_text, replace_text)
# Open the file for writing
with open(file_spec, 'w') as file:
# Write the modified contents back to the file
file.write(modified_contents)
# Print a success message
print(f"Modification successful: Replaced '{search_text}' with '{replace_text}' in {file_spec}")
except IOError as e:
# Print an error message if there was an issue with file operations
print(f"Error: {e}")
def main():
# Check if the correct number of command line arguments are provided
if len(sys.argv) != 4:
print("Usage: python modify.py fileSpec \"from\" \"to\"")
return
# Extract the command line arguments
file_spec = sys.argv[1]
search_text = sys.argv[2]
replace_text = sys.argv[3]
# Call the function to modify the smb.conf file

While troubleshooting an Internet connection problem for your network, you restarted the modem and then the router. The router is now communicating with the Internet, which you can confirm by observing the blinking light on the router's WAN indicator. However, now your laptop is not communicating with the router.

Answer:
d. ipconfig /release
b. ipconfig /renew
a. ping
c. nslookup microsoft.com
Explanation:
A router can be defined as a network device that is designed typically for forwarding data packets between two or more networks based on a well-defined routing protocol.
Basically, it is an electrical device or node that is designed to connect two (2) different networks (in different locations) together and allows them to communicate.
Generally, routers are configured using a standard routing protocol with an IP address as the default gateway.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
Basically, a DHCP server is designed to automatically assign internet protocol (IP) address to network devices connected to its network using a preconfigured DHCP pool and port number 67.
On a related note, when a computer that is configured with DHCP cannot communicate or obtain an IP address from the DHCP server, the Windows operating system (OS) of the computer automatically assigns an IP address of 169.254.33.16, which typically limits the computer to only communicate within its network.

Answers
Answer:
"In inner for loop" is printed twice.
Answer: C. 2
Explanation:
Code:
int main()
{
int limit = 0;
for (int i =0; i>=limit; i-=2) {
for (int j = i; j <= 1; ++j){
cout << "In inner for loop" << endl;
}
cout << "In outer for loop" << endl;
}
return 0;
}
Output:
In inner for loop
In inner for loop
In outer for loop
The output "In inner for loop" print twice.
Thus, option (c) is correct.
In the given code example, the inner for loop has a condition j <= 1.
This condition means that the loop will execute as long as j is less than or equal to 1.
However, the initial value of j is i, and the value of i decreases by 2 in each iteration of the outer for loop.
When i = 8, the inner loop has the condition j ≤ 1.
The loop will iterate as long as j is less than or equal to 1.
So the inner loop executes twice: once when j = 8, and then when j = 9. The statement "In inner for loop" prints twice.
Therefore, the output print twice.
Thus, option (c) is correct.

JMP LIST:
The JMP command can be used to execute an unconditional jump, JMP LIST[DX] is the label's name. The JMP LIST[DX] program is being used to transfer control of its flow programs to the specified section. It is the segment to which the flow control is transmitted.c)
JMP NEAR PTR[DI+3]:
Unconditional jumps could be done with the JMP command as you'll see, the label is JMP NEAR PTR[DI+3]. It's being used to transmit flow control to a particular section, throughout this case [DI+3].
