Configure DHCP reservation, enable it, assign IP, save configuration, to configure reservation on firewall.
1. Configure the DHCP Reservation: The first step in setting up a DHCP reservation on the firewall is to configure the DHCP reservation. This is done by adding the necessary parameters, such as the IP address, MAC address, and hostname, for each device that needs to be reserved.
2. Enable DHCP Reservation: Once the DHCP reservation is configured, the next step is to enable the DHCP reservation. This is done by enabling the DHCP reservation option within the firewall’s configuration settings. This will allow the firewall to assign the specified IP address to the device with the specified MAC address.
3. Assign IP Address: The third step is to assign the IP address to the device with the specified MAC address. This is done by entering the IP address into the appropriate field and then clicking the “Assign” button.
4. Save the Configuration: After the IP address has been assigned, the final step is to save the configuration. This is done by clicking the “Save” button, which will save the configuration and make the DHCP reservation active.
By following these steps, users can easily configure a DHCP reservation on their firewall and ensure that the same IP address is always assigned to the specified device.

The given program reads a list of single-word first names and ages (ending with -1), and outputs that list with the age incremented. The program fails and throws an exception if the second input on a line is a string rather than an int. At FIXME in the code, add a try/catch statement to catch ios_base::failure and output 0 for the age.
Ex: If the input is:
Lee 18
Lua 21
Mary Beth 19
Stu 33
-1
then the output is:
Lee 19
Lua 22
Mary 0
Stu 34
Note that the code for the above instructions is given as follows:
#include <iostream>
#include <string>
#include <ios>
using namespace std;
int main() {
string name;
int age;
while (cin >> name && name != "-1") {
try {

age++;
cout << name << " " << age << endl;
} catch (ios_base::failure& e) {
cout << name << " " << 0 << endl;
}
}
return 0;

What is the rationale for the above response?The try/catch statement is used to catch the exception ios_base::failure that is thrown when the second input on a line is not an integer.
If an exception is thrown, the code inside the catch block is executed, which outputs the name and 0 as the age. If no exception is thrown, the code inside the try block is executed, incrementing the age by 1 and outputting the name and the incremented age.

Spotify interrogated 400 clients and observed that on average, a client streams every week 42 different artists! However, the standard deviation for this number is 15. What is the confidence interval for the true average number of artists listened by all Spotify clients for a 10% alpha risk?
We can say with 90% confidence that the true average number of artists listened by all Spotify clients is between 40.75 and 43.25.
What is standard deviation?The degree of data dispersion from the mean is indicated by the standard deviation.
A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
To calculate the confidence interval for the true average number of artists listened by all Spotify clients, we can use the formula:
Confidence interval = sample mean ± (t-value x standard error)
Standard error = 15 / sqrt(400) = 0.75
Next, we need to find the t-value. Since the sample size is 400, we have 399 degrees of freedom.
Using a t-table or a t-distribution calculator with a significance level of 0.10 and 399 degrees of freedom, we find the t-value to be approximately 1.645.
Now, we can plug in the values to get the confidence interval:
Confidence interval = 42 ± (1.645 x 0.75)
Confidence interval = [40.75, 43.25]
Thus, we can state with 90% certainty that between 40.75 and 43.25 artists are actually being listened to on average by all Spotify users.

3. (6pts) Let h1 and h2 be two hash functions. Show that if either h1 or h2 is collision resistant, then the hash function h(x) = h1(x) ||h2(x), is collision resistant. (here "| means concatenation)
As we have shown that h1 or h2 is a collision-resistant function, thus h1(x) || h2(x) is collision-resistant. Given, h1 and h2 be two hash functions. And, | denotes concatenation.
Proof: Suppose we have two input values 'x' and 'y' and h1 and h2 are the hash functions such that: h1(x) = h1(y), h2(x) = h2(y)
Let's define h(x) = h1(x) || h2(x) and h(y) = h1(y) || h2(y).Now we have to show that h(x) = h(y).
Then h1(x) || h2(x) = h1(y) || h2(y) implies that h1(x) = h1(y) and h2(x) = h2(y).It means either h1 or h2 is collision-resistant, then it must be hard to find different inputs with the same output. Thus h1(x) || h2(x) is collision-resistant.
For given hash functions h1 and h2, let's suppose that h1 is a collision-resistant function. Now, if we take any input 'x' and 'y', then we have h1(x) = h1(y) then x and y must be same to get the same output.
If we take another hash function h2 and x and y, then it is not sure that they are same as we have taken any function. But we can see that whatever the value of x or y, we can't get the same output until we take the same values. Thus h1(x) || h2(x) is collision-resistant.

You have a desktop computer that uses a 250-watt power supply. You recently added a four-disk RAID 10 array to the system, and now it spontaneously shuts down. Which of the following would MOST likely rectify this issue?
answer choices
O Upgrade to smaller capacity hard drives.
O Use the switch on the power supply to switch from 115 VAC to 230 VAC.
O Upgrade to a power supply that provides more volts.
O Upgrade to a power supply that provides more watts.
A very modest computer with few data processing resources requires at least 400 watts for safe operation. Correct answer: Upgrade to a power supply that provides more watts.
Minimum power requirements of a PC:First of all, the minimum power requirements for normal desktop operation today far exceed 250 watts, and 400 watt power supply is recommended at least for a modest computer.
In fact, I think most computers today run on more than 600 watts. Therefore, if 4 hard drives are installed for a system that normally only uses one, obviously 250 watts cannot cover the power needs that these devices adding the total computer system requirement.
Finally, it can be concluded that the optimal solution to the problem is the last option that says: upgrade to a power supply that provides more watts.

A technician is installing a SOHO router to an after school community center. The customer would like to keep children from accessing inappropriate while browsing the web.
What actions would help this goal be accomplished?
a. Enable content filtering
b. port forwarding
c. MC address filtering.
Answer:A
Explanation:
Content filtering would allow this to happen.
Port forwarding only allows you to connect to other computers while on a private network. It does not filter out anything.
Assuming you meant MAC Address filtering, this would not solve the issue either. This would only disallow any computer without the specified MAC address to connect to the network.
Therefore, content filtering is the only answer that makes sense.
