When saving messages as drafts, it’s important to remember that your draft will not go live unless _______. Choose only ONE best answer. A. you have admin permissions or higher B. you have scheduled it or clicked Publish C. you have unlocked the draft for editing D. you have approval from a super-admin
Answer:
Option (b) is the correct answer.
Explanation:
"Drafts" is a folder of messaging software or mail software whose works are to save the message until the user does not want to send it. So to send the message from drafts, the user needs to edit the message first then he can able to send that message. The above question asks that how a user can send the draft message. Option b suggests that a user needs to click send to send the draft message.
Hence it is a right option while the reason behind the other option is invalid are as follows--
Option a suggests that a user needs admin permission to send this but if that is his account then no need for admin permission.Option c suggests to unlock the draft but the draft folder is not locked.Option d suggests to take permission from a superuser but that is not required.A user saves a password on a website the user logs into from a desktop. Under which circumstances will the password be saved on other devices?
(a)Same browser
(b)Same encryption certificate
(c)Same Internet provider
(d)Same operating system
Answer:
Same Browser
Explanation:
If we access some password for some website in from some computer. It will be saved in the browser of the computer. Whenever we access the website from some other computer and we want to login we need the same browser.
In this process, browser is sync by using our mailing address. Whenever we want to access the pasword of different website from some other device, we need to sync that device browser with the same mailing address.
In this process all password that are saved on other device may access from any device.

Express different genes
Explanation:
Basically DNA is written into RNA which is later converted into proteins, gene expression involves the heritable data in a gene and DNA arrangement being made into a gene product like Protein. the cells in the muscle and nerves have different way of gene expression.
Case-Based Critical Thinking QuestionsCase 1: Tony’s Pizza & PastaTony’s Pizza & Pasta restaurant uses an application to update and display menu items and the related price information.Which of the following statements assigns the daily special of lasagna to Tuesday? a.
strSpecial(5) = "rigatoni"
b.
strSpecial(6) = rigatoni
c.
strSpecial(5) = rigatoni
d.
strSpecial(6) = "rigatoni"
None of the provided options directly answers the question due to a misunderstanding or a potential typo since they involve assigning "rigatoni" instead of "lasagna" and none select Tuesday correctly based on zero-based indexing for days of the week in programming.
Explanation:The question involves assigning the daily special of lasagna to Tuesday in a programming context, likely using an array to manage menu items by day of the week. Arrays in programming are zero-based, meaning the first element is at index 0. Therefore, Tuesday, being the second day of the week under conventional standards starting with Monday, would be at index 1 in the array. However, none of the given options directly mention "lasagna" or Tuesday explicitly, so we must infer based on standard array indexing and typical syntax for assigning values in programming languages like Python or Java.
Given the options, however, none correctly assigns "lasagna" to Tuesday due to the mix-up in the days and the item mentioned. The correct approach to assign "lasagna" to Tuesday would look something like strSpecial[1] = "lasagna", considering a hypothetical array strSpecial where days of the week are mapped to menu items. Since this option is not available, it points to a possible typo or error in the question's formatting.

________ is defined as how we form impressions of and make inferences about other people. Attribution theory Social perception Social inference Social encoding
Answer:
Social Perception is defined as how we form impressions of and make inferences about other people.
Explanation:
Attribution theory is such theory in psychology which tells us that people determine the behavior of others with the help of their attitude, feelings or belief. For example, if he is not smiling today then he is sad.Social perception is defined as the way of forming impression about others so this is true in our case.Social inference tell us about the reasoning behind the social behavior of people on the basis of some facts.Social encoding is simply the translation of behavior or any other things into our thoughts or beliefs.When a structure must be passed to a function, we can use pointers to constant data to get the performance of a call by __________ and the protection of a call by __________.

Assume you are a network consultant for a company that is designing a private WAN to communicate between five locations spread throughout a city. You want to tell the company president that this WAN will use a design for maximum uptime to all locations. Which of the designs should you use
Answer:
A mesh network design
Explanation:
In designing local area networks, we can follow one of several network topologies, some of these are; bus, star, ring, star-ring hybrid, mesh, etc. In a mesh topology, all the PCs are inter-connected to each other such that the computers do not send signals, they also act as signal relay to others within the network, considering that in this question scenario the goal is to acheive maximum uptime at all locations, a mesh design will be the best.
Final answer:
For a private WAN with maximum uptime, a mesh topology should be used due to its redundancy, with a full mesh offering the highest resilience. However, due to potential high costs, a partial mesh might be deployed, prioritizing critical connections and possibly using Quality of Service features for additional reliability.
Explanation:
If you are consulting for a company that needs a private Wide Area Network (WAN) with maximum uptime between its five locations spread throughout a city, the most robust design you should recommend is a mesh topology. A mesh topology provides each location with a direct connection to every other location. This redundancy means that if any single connection fails, the network communication can still proceed uninterrupted via alternative routes. For even greater resilience, you could consider a full mesh design, where each node has a direct connection to each other node, ensuring the highest level of redundancy and uptimes.
However, full mesh networks can be costly due to the high number of links and networking equipment required. An alternative with a balance of cost and resilience would be a partial mesh network, where not all systems are directly connected, but there are still enough interconnections to maintain communication in case one or a few links go down. It is essential to evaluate the criticality of each site to determine which connections are most necessary. Additionally, implementing Quality of Service (QoS) features and having backup links for the most critical connections will further enhance the network's robustness.

How many attendees are at a convention if 150 of the attendees are neither female nor students, one-sixth of the attendees are female students, two-thirds of the attendees are female, and one-third of the attendees are students?
Answer:
900
Explanation:
Let x be no. of attendees.
No. of students = x/3
No. of female students = x/6 = (1/2)(x/3) = (1/2) no. of students
This implies (1/2) of students are male. So,
No of male students = (1/2)(x/3) = x/6 .......eq (1)
No. of female attendees = 2x/3
No of male attendees = x - (2x/3) = x/3 ...eq (2)
Using eq(1) and eq(2)
No of male non-student attendees = (x/3) - (x/6) = x/6 ....eq(3)
No of male non-student attendees= 150 (Given in question) ....eq(4)
Using eq(3) and eq(4)
=> x/6=150
=> x=150*6
=> x=900 (Answer)

Answer:
The answer is -rw-rw-r--
Explanation:
This is a permission string which refers to read and write (modify) permissions to owner and group only and read only permission for all others.
There are three types of permissions: read (r), write(w), and execute(x).
In the above string, r stands for read and w stands for write permissions. Read (r) permission allows the contents of the file to be viewed.
Write (w) permission allows modification of the contents of that file. It gives permission to edit (e.g. add and remove) files.
The first dash "-" refers to the type of file. The next rw- define the owner’s permission to the file. so the owner has permission to read and write a file only. The next rw- refers to the group permission. The members of the same group have permission to read and write a file only just as the owner. The last r-- means that all other users can only read/ view the file. In the first rw- the "-" means to remove or deny access. This means owner is granted permission read and write the file only but he cannot execute (x) the file contents. 2nd rw- means the same but for group and lastly there are two "--" after r. The first "-" denies write access and second one denies execute access.

Consider the following recursive method. public static void whatsItDo(String str) { int len = str.length(); if(len > 1) { String temp = str.substring(0, len – 1); whatsItDo(temp); System.out.println(temp); } } What is printed as a result of the call whatsItDo("WATCH")?
(A) WATC

WATCH
Answer:
The answer is C.
W
WA
WAT
WATC
Explanation:
When the recursive method is called using whatsItDo("WATCH"), it works like this:
First the length of the argument is gotten and assigned to len.
Next if the length is greater than 1, execution enter the defined block
Inside the block, a substring is created from the beginning to less than 1 the end (0 to len - 1) and it is assigned to temp.
Then, the method is called again with whatsItDo("WATC").
The iteration continue and the next called method is whatsItDo("WAT"), followed by whatsItDo("WA"), followed by whatsItDo("W").
When whatsItDo("W") is called the condition will fail. So, the execution will pick up from:
whatsItDo("WA") where "W" will be displayed, then
whatsItDo("WAT") where "WA" will be displayed, then
whatsItDo("WATC") where "WAT" will be displayed, then
whatsItDo("WATCH") where "WATC" will be displayed.
And the program will finished execution.
Final answer:
The recursive method whatsItDo prints each substring of "WATCH" after each recursive call, resulting in 'WATC', 'WAT', 'WA', and 'W' being printed in that order, corresponding to option (A).
Explanation:
The recursive method described in the question prints a series of progressively shorter substrings of the original string "WATCH". This is because each recursive call to whatsItDo removes the last character from the string and prints the substring after making the recursive call. The method stops making recursive calls once it reaches a substring with a length of 1, and as the recursive calls return, it prints each of the substrings starting from the shortest to the second longest.
Thus, when whatsItDo("WATCH") is called, the output will be a series of substrings without the last character:
WATCWATWAWThis corresponds to option (A) as follows:

An office manager must choose a five-digit lock code for the office door. The first and last digits of the code must be odd, and no repetition of digits is allowed. How many different lock codes are possible?
Answer:
6720 lock codes
Explanation:
The numbers to be chosen from are:
0 1 2 3 4 5 6 7 8 9
The odd numbers are five in number which are: 1 3 5 7 9
The even numbers are five in number which are: 0 2 4 6 8
If the first number is odd, therefore, it can be chosen in five ways
After the first number is chosen, there are 4 left odd numbers so the last number can be chosen in four ways.
There are 8 left numbers after they are chosen, so the second number can be chosen in eight ways
Third number can be chosen similarly, in seven ways
Fourth number can be chosen in six ways
Hence, the number of different combinations are:
5*4*8*7*6 = 6720 combinations
"When analyzing the IDS logs, the system administrator notices connections from outside of the LAN have been sending packets where the Source IP address and Destination IP address are the same. There have been no alerts sent via email or logged in the IDS. Which type of an alert is this?
This is false negative. To be marked for alert.
Explanation:
The network administrator or network engineer when he or she is analyzing IDS logs and founded the ip address is same on source and destination both in outside side.
So the either TCPIP address has to change to be scanned across the network. Since same IP address is same pinging rate will high and pinging the same workstation or desktop or laptop.
Alert will not generate because both tcpip address same and if pinging is success. Ids logs generates based true negative, true positive and false positive will not generate any alert.

A. Maximum password age
B. Longer passwords
C. Force use of all four types of characters (uppercase, lowercase, numbers, symbols)
D. Computer generated passwords
Answer:
B. Longer passwords
Explanation:
If the password is longer, it requires more incorrect attempts to find it, so the system could identify a potential hacker attempt. Smaller but more complex passwords could be identified by mistype or forgotten passwords.
