Answer: your worksheet contains confidential information in column c; to prevent others who use your worksheet from seeing the data, you can HIDE column c.
Explanation:
consider the following method. public boolean checkindexes(double[][] data, int row, int col) { int numrows = data.length;if (row < numRows){int numCols = data[0].length;return col < numCols;} else {return false;}}. Consider the following variable declaration and initialization, which appears in a method in the same class as checkIndexes. Which of the following method calls returns a value of true ? A checkIndexes(table, 4, 5)B checkIndexes(table, 4, 6)C checkIndexes(table, 5, 4)D checkIndexes(table, 5, 6)E checkIndexes(table, 6, 5)
the following variable declaration and initialization, which appears in a method in the same class as check indexes A check indexes (table, 4, 5)
As per the details given in problem statement double[][] table = new double[5][6]; is initialized
we can observe that table is a 2-dimensional array of double data type and variable
Number of rows in table = 5
Number of columns in table = 6
Note: In the code,
1) In Line 3 data.length returns the number of Rows of a table array
2) In Line6 data[0].length returns the number of Columns of the table array
3) We can observe that the given piece of code checks whether the given index is valid or not for the table array
Tracing:
For check indexes(table, 4, 5):
From Line1 instruction:
double data is a table array
int row is 4
int col is 5
From Line3 instruction:
int numRows is 5
From Line4 instruction:
if condition row < numRows is true
From Line6 instruction:
int numCols is 6
From Line7 instruction:
col < numCols is true and the value true will be returned
If we try the same tracing process for options B, C, D, E the boolean value false will be returned. Because the index values for B, C,D, E are invalid. see below details for information
B check indexes(table, 4, 6) fails in if condition at Line7
C check indexes(table, 5, 4) fails in if condition at Line4
D check indexes(table, 5, 6) fails in if condition at Line4
E-check indexes(table, 6, 5) fails in if condition at Line4
So the A check indexes (table, 4, 5) only return true among all options.

You need to configure a wireless network. You want to use WPA2 Enterprise. Which of the following components will be part of your design? (Select two.)
Open authentication
WEP encryption
TKIP encryption
Preshared keys
AES encryption
802.1x
For the WPA2 Enterprise componets :Wireless network configuration is required. The two components of WPA2 Enterprise are AES encryption and 802.1x.
A network security method frequently used on Wi-Fi wireless networks is Wi-Fi Protected Access 2. It is an improvement on the original WPA technology, which was created to take the place of the less advanced and secure WEP. Since 2006, WPA2, which is based on the IEEE 802.11i technical standard for data encryption, has been deployed on all certified Wi-Fi gear.
Anyone within the network's range may be able to see the communication when WPA2 is configured with its strongest encryption option, but it is scrambled with the most recent encryption standards.There are various kinds of WPA2 security keys. The length of a WPA2 Pre-Shared Key is 64 hexadecimal digits. Home networks frequently employ this technique. WPA2 PSK and WPA2 Personal mode refer to the same underlying technology, and are frequently interchanged by home routers.

What is recursive function?A recursive function is a programming construct that executes by referencing itself. Recursive procedures can be straightforward or complex. They enable more effective code writing, for example, when listing or compiling collections of numbers, strings, or other variables using a single repeated procedure.
Code for recursive functions frequently uses setups for loops, in which the initial variable is used repeatedly while being changed by the loop. The factorial, which multiplies an integer by itself while decreasing it incrementally, is a straightforward illustration of a recursive function. Recursive functions can refer to a wide variety of self-referencing looping functions, such as those where n = n + 1 given an operating range.

Consider the following method:public static int mystery(int[] nums) { int total = 0; for (int k = 0; k < nums.length/2; k++) total = total + nums[k]; return total; } Assume that the array test has been declared and initialized as follows.int[] test = {1, 3, 2, 5, 8, 7, 0}; What value will be returned as a result of the call mystery(test)?46111326
After compiling the method mystery value return as a result of the total will be 6.
When the function mystery will be called
nums = [1, 3, 2, 5, 8, 7, 0].
total = 0
in loop index of k is 0, and loop will continue till (nums.length / 2) - 1 that is 2.
So, in first iteration value of total will be 1 in index 0.
In index 1 value of total will be 1+3 = 4
In index 2 value of total will be 4+2 = 6
Hence, the value of total will be 6.
A loop is a series of instructions that are repeatedly carried out up until a specific condition is met.
Initialization
When the loop begins, the first condition is the one that is run once. Here, we have the option of initialising the variable or using one that has already been initialised. It's an optional requirement.
Condition
The second condition is executed each time the loop's state is checked. Until the condition is false, execution keeps going. Either true or false must be returned as a boolean value. It's an optional requirement.
Increment/Decrement
The variable value is increased or decreased as a result. It's an optional requirement.
Statement
Every time the second condition is met, the loop's statement is carried out.

How many rows of data are returned after executing the following statement?
SELECT DEPT_ID, SUM(SALARY) FROM EMP
GROUP BY DEPT_ID HAVING SUM(NVL(SALARY,100)) > 400;
Assume the EMP table has ten rows and each contains a SALARY value of 100, except for one, which has a null value in the SALARY field. The first and second five rows have DEPT_ID values of 10 and 20, respectively.
2 rows of data are returned after executing the following statement.
Two groups are created based on their common DEPT_ID values. The group with DEPT_ID values of 10 consists of five rows with
SALARY values of 100 in each of them. Therefore the SUM(NVL(SALARY,100)) function returns 500 for this group and it satisfies the
HAVING SUM(SALARY) > 400 clause. The group with DEPT_ID values of 20 has four rows with SALARY values of 100 and one row with
a null SALARY SUM(NVL(SALARY,100)) returns 500 and this group satisfies the HAVING clause. Therefore two rows are returned.
