The correct answer to this open question is the following.
Unfortunately, you did not provide any context or background about the situation of Sally and the problem with her slides. We do not know it, just you.
However, trying to be of help, we can comment on the following general terms.
When someone does not meet professional expectations, this means that this individual did not prepare her presentation, lacked technical skills, did not included proper sources, or missed the proper visual aids to make the presentation more attractive and dynamic.
What Sally can improve about her slides is the following.
She can design a better structure for the presentation to have more congruence.
Sally has to clearly establish the goal or goals for her presentation.
She has to add many visuals instead of plain text. This way she can better capture the interest of her audience.
If she can use more vivid colors instead of pale or dark ones, that would be best.
No paragraphs unless necessary. She better uses bullet points.
Take care of the tone of her voice. During her practice, she can record her vice to check how it sounds.

d. all statements are correct
Answer:
The correct statement regarding DCE and DTE interfaces is:
c. DTE and DCE describes the interface and direction of data flow between devices; a single device may have both types of interfaces.
Explanation:
DTE stands for Data Terminal Equipment. It is a device that initiates or controls a device's serial connection. The term DCE stands for Data Communications Equipment. It is a device that is used to a modem or other communication interfaces to the DTE device. DTE is a communication receptor, while DCE is a communication broadcaster or distributor.
Carl is planning for a large advertising campaign his company will unveil. He is concerned that his current e-commerce server farm hosted in a public cloud will be overwhelmed and suffer performance problems. He is researching options to dynamically add capacity to the web server farm to handle the anticipated additional workload. You are brought in to consult with him on his options. What can you recommend as possible solutions
Answer:
Cloud Bursting
Explanation:
One of the best possible solutions for this scenario would be Cloud Bursting. This is a solution of using Cloud Server services to handle the server farm workload. The difference is that Cloud Bursting allows the company to use the Cloud services only when their own personal web server farms hit peak demand and can no longer handle the incoming demand. The excess demand is outsourced to the Cloud Server and lets them handle it dynamically without the company having to add any additional hardware to their server farm.

How many fingers do you need to type floor
Answer:
About 0-1 fingers at minimum
Explanation:
you can type with your toes/elbow as well. Any body part really.
To type the word "floor" on a regular keyboard layout, you would generally need six fingers: three on your left hand and three on your right.
Your index finger (usually used for the "F" key) on your left hand would be utilised for the letter "f." Your middle finger (which is normally used for the "D" key) would be utilised for the letter "l."
Finally, your ring finger (which is normally used for the "S" key) would be utilised for the letter "o."
Your index finger (usually used for the "J" key) on your right hand would be utilised for the letter "o." Your middle finger (which is normally used for the "K" key) would be utilised for the second letter "o."
Finally, your ring finger (which is normally used for the "L" key) would be utilised for the letter "r."
Thus, on a typical keyboard layout, you would type the word "floor" with three fingers from each hand.

You work in an office that uses Linux and Windows servers. The network uses the IP protocol. You are sitting at a Windows workstation. An application you are using is unable to connect to a Windows server named FileSrv2. Which command can you use to determine whether your computer can still contact the server?
Answer:
PING
Explanation:
To check if there's still connectivity between the computer and server, I would use the ping command.
The ping command is primarily a TCP/IP command. What this command does is to troubleshoot shoot. It troubleshoots connection and reachability. This command also does the work of testing the name of the computer and also its IP address.

A computer with a five-stage pipeline deals with conditional branches by stalling for the next three cycles after hitting one. How much does stalling hurt the performance if 20% of all instructions are conditional branches
Answer:
The stalling hurt the performance by 60%.
Explanation:
This can be calculated as follows:
Value of CPI ideally taken by pipeline = 1
From the question, we are given:
Stall frequency = 20%,
Number of frequency = 3
Therefore, we have:
Cycles per instruction (CPI) of the architecture = Value of CPI ideally taken by pipeline + (Stall frequency * Number of frequency) = 1 + (20% * 3) = 1.60
Amount by which the stalling hurt the performance = Cycles per instruction (CPI) of the architecture Value of CPI ideally taken by pipeline = 1 - 0.60 = 0.60, or 60%
Therefore, the stalling hurt the performance by 60%.

Explanation:
Please find the following Excel form for calculating the bonus as required. Please ensure the equation is duplicated even so, with the sign "=." It is possible to insert this formula into cell L12. Then cut/paste the cell into other L12:L39 cells.
[tex]=IF(AND(G12/F12 \geq \$L \$7,J12 \leq \$L\$8)=TRUE,\$L\$9,0)[/tex]
The mixed microbial reference here is used in L7, L8, and L9 so these cell references are not moved whenever the formula is copied to L12:L39.
Please verify that whenever the copy has also been copied, the cell formula appears beneath in each cell.
It must be as below in L12.
[tex]=IF(AND(G12/F12 \geq \$L\$7,J12\leq \$L\$8)=TRUE,\$L\$9,0)[/tex]
It must be as follows in L13.
[tex]=IF(AND(G13/F13\geq \$L\$7,J13\leq \$L\$8)=TRUE,\$L\$9,0)[/tex]

Add (total) all the number in the list (below) using a for loop, but skip over the number at index 3.
numbers = [10,20,30,40,50,60,100]
Answer:
The program in Python is as follows:
numbers = [10,20,30,40,50,60,100]
total = 0
for i in range(len(numbers)):
if i != 3:
total+=numbers[i]
print(total)
Explanation:
This initializes the list
numbers = [10,20,30,40,50,60,100]
Set total to 0
total = 0
This iterates through numbers
for i in range(len(numbers)):
This ensures that the index 3, are not added
if i != 3:
total+=numbers[i]
Print the calculated sum
print(total)

A recursive method may call other methods, including calling itself. Creating a recursive method can be accomplished in two steps. 1. Write the base case -- Every recursive method must have a case that returns a value or exits from the method without performing a recursive call. That case is called the base case. A programmer may write that part of the method first, and then lest. There may be multiple base cases.Complete the recursive method that returns the exponent of a given number. For e.g. given the number 5 and the exponent 3 (53) the method returns 125. Note: any number to the zero power is 1. Note: Do not code for the example. Your method must work for all given parameters! Use this as your method header: public static int raiseToPower(int base, int exponent)
Answer:
Explanation:
The following code is written in Java. It creates the raiseToPower method that takes in two int parameters. It then uses recursion to calculate the value of the first parameter raised to the power of the second parameter. Three test cases have been provided in the main method of the program and the output can be seen in the attached image below.
class Brainly {
public static void main(String[] args) {
System.out.println("Base 5, Exponent 3: " + raiseToPower(5,3));
System.out.println("Base 2, Exponent 7: " + raiseToPower(2,7));
System.out.println("Base 5, Exponent 9: " + raiseToPower(5,9));
}
public static int raiseToPower(int base, int exponent) {
if (exponent == 0) {
return 1;
} else if (exponent == 1) {
return base;
} else {
return (base * raiseToPower(base, exponent-1));
}
}

/* From the information provided, For now will consider the name of table as TRIPGUIDES*/
/*In all the answers below, the syntax is based on Oracle SQL. In case of usage of other database queries, answer may vary to some extent*/
1.
Select R.Reservation_ID, R.Trip_ID , C.Customer_Num,C.Last_Name from Reservation R, Customer C where C.Customer_Num=R.Customer_Num ORDER BY C.Last_Name
/*idea is to select the join the two tables by comparing customer_id field in two tables as it is the only field which is common and then print the desired result later ordering by last name to get the results in sorted order*/
2.
Select R.Reservation_ID, R.Trip_ID , R.NUM_PERSONS from Reservation R, Customer C where C.Customer_Num=R.Customer_Num and C.LAST_NAME='Goff' and C.FIRST_NAME='Ryan'
/*Here, the explaination will be similar to the first query. Choose the desired columns from the tables, and join the two tables by equating the common field
*/
3.
Select T.TRIP_NAME from TRIP T,GUIDE G,TRIPGUIDES TG where T.TRIP_ID=TG.TRIP_ID and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Abrams' and G.FIRST_NAME='Miles'
/*
Here,we choose three tables TRIP,GUIDE and TRIPGUIDES. Here we selected those trips where we have guides as Miles Abrms in the GUIDES table and equated Trip_id from TRIPGUIDES to TRIP.TRIP_Name so that can have the desired results
*/
4.
Select T.TRIP_NAME
from TRIP T,TRIPGUIDES TG ,G.GUIDE
where T.TRIP_ID=TG.TRIP_ID and T.TYPE='Biking' and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Boyers' and G.FIRST_NAME='Rita'
/*
In the above question, we first selected the trip name from trip table. To put the condition we first make sure that all the three tables are connected properly. In order to do so, we have equated Guide_nums in guide and tripguides. and also equated trip_id in tripguides and trip. Then we equated names from guide tables and type from trip table for the desired results.
*/
5.
SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='2016-07-23' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM
/*
The explaination for this one will be equivalent to the previous question where we just equated the desired columns where we equiated the desired columns in respective fields and also equated the common entities like trip ids and customer ids so that can join tables properly
*/
/*The comparison of dates in SQL depends on the format in which they are stored. In the upper case if the
dates are stored in the format as YYYY-MM-DD, then the above query mentioned will work. In case dates are stored in the form of a string then the following query will work.
SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='7/23/2016' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM

{SELECT TRIP_ID FROM TRIP T WHERE STATE='ME'}
/*
In the above question, we firstly extracted all the trip id's which are having locations as maine. Now we have the list of all the trip_id's that have location maine. Now we just need to extract the reservation ids for the same which can be trivally done by simply using the in clause stating print all the tuples whose id's are there in the list of inner query. Remember, IN always checks in the set of values.

Unlike IN, Exist returns either true or false based on existance of any tuple in the condition provided. In the question above, firstly we checked for the possibilities if there is a trip in state ME and TRIP_IDs are common. Then we selected reservation ID, trip ID and Trip dates for all queries that returns true for inner query

We have used here double nested IN queries. Firstly we selected all the trips which had paddling type (from the inner most queries). Using the same, we get the list of guides,(basically got the list of guide_numbers) of all the guides eds which were on trips with trip id we got from the inner most queries. Now that we have all the guide_Nums that were on trip with type paddling, we can simply use the query select last name and first name of all the guides which are having guide nums in the list returned by middle query.

Resize vector countDown to have newSize elements. Populate the vector with integers {newSize, newSize - 1, ..., 1}. Ex: If newSize = 3, then countDown = {3, 2, 1}, and the sample program outputs:
#include
#include
using namespace std;
int main() {
vector countDown(0);
int newSize = 0;
int i = 0;
newSize = 3;
STUDENT CODE
for (i = 0; i < newSize; ++i) {
cout << countDown.at(i) << " ";
}
cout << "Go!" << endl;
return 0;
}
Answer:
Following are the code to the given question:
#include <iostream>//defining header file
#include <vector>//defining header file
#include <numeric>//defining header file
using namespace std;
int main()//main method
{
vector<int> countDown(0);//defing an integer array variable countDown
int newSize = 0;//defing an integer variable newSize that holds a value 0
int i = 0;//defing an integer variable i that initialize with 0
newSize = 3;// //use newSize to hold a value
countDown.resize(newSize,0);// calling the resize method that accepts two parameters
for (i = 0; i < newSize; ++i)//defining a loop that reverse the integer value
{
countDown[i] = newSize -i;//reverse the value and store it into countDown array
cout << countDown.at(i) << " ";//print reverse array value
}
cout << "Go!" << endl;//print message
return 0;
}
Output:
3 2 1 Go!
Explanation:
In the given code inside the main method an integer array "countDown" and two integer variables "newSize and i" is declared that initializes a value that is 0.
In the next step, an array is used that calls the resize method that accepts two parameters, and define a for a loop.
In this loop, the array is used to reverse the value and print its value with the message.
Write a function int checkBalance(char exp[]); that can take an expression as input and check whether the parenthesis used in that expression are valid or invalid. It returns 1 if it is valid, and returns 0 if it is not valid.For example, the following expressions are valid: [ A * {B (C D)}] and [{()()}]The following expressions are invalid: [ A * {B (C D})], [ { ( ] ) ( ) }
Answer:
Explanation:
The following code is written in Java. It uses for loops to loop through the array of characters, and uses IF statements to check if the symbols in the expression are balanced. If so it returns true, otherwise it breaks the function and returns false. Two test cases have been provided in the main method and the output can be seen in the attached image below.
import java.util.ArrayList;
class Brainly {
public static void main(String[] args) {
char[] exp = { '[', 'A', '*', '{', 'B', '(', 'C', 'D', ')', '}', ']'};
char[] exp2 = {'[', 'A', '*', '(', 'C', '}', ']'};
System.out.println(checkBalance(exp));
System.out.println(checkBalance(exp2));
}
public static boolean checkBalance(char exp[]) {
ArrayList<Character> symbols = new ArrayList<>();
for (char x: exp) {
if ((x =='[') || (x == '{') || (x == '(')) {
symbols.add(x);
}
if (x ==']') {
if (symbols.get(symbols.size()-1) == '[') {
symbols.remove(symbols.size()-1);
} else {
return false;
}
}
if (x =='}') {
if (symbols.get(symbols.size()-1) == '{') {
symbols.remove(symbols.size()-1);
} else {
return false;
}
}
if (x ==')') {
if (symbols.get(symbols.size()-1) == '(') {
symbols.remove(symbols.size()-1);
} else {
return false;
}
}
}
return true;
}
}

you are installing two new hard drives into your network attached storage device your director asks that they be put into a raid solution that offers redundndancy over performance which would you use
Question options:
a. RAID 0
b. RAID 1
c. RAID 5
d. RAID 6
e. RAID 10
Answer:
d. RAID 6
Explanation:
RAID is Redundant Array of Inexpensive/Independent Disks. RAID combines low cost physical hard disk drives in one hard disk drive. RAID is used to achieve data redundancy(data backup but with synchronization) or improved performance or both.
To get what the director requires he would need to use RAID 6. RAID 6 is RAID level optimized to achieve data redundancy but with slow performance.
