you have hired ten new temporary employees to be with the company for three months.how can you make sure that these users can only log on during regular business hours?answerconfigure day/time restrictions in user accountsconfigure account expiration in user accountsconfigure account policies in group policyconfigure account lockout in group policy
Answers
To ensure that the ten new temporary employees can only log on during regular business hours, you should configure day/time restrictions in user accounts. This will allow you to set specific time frames during which the employees will have access to the system, thus restricting their logon hours to regular business hours.
To ensure that your new temporary employees can only log on during regular business hours, you can use a few different methods. Here are a few options:
1. Configure day/time restrictions in user accounts: You can set up specific days and times during which the user account is allowed to log on. This can be done by going to the user account properties in Active Directory, selecting the "Logon Hours" tab, and specifying the allowed logon times. This will prevent the user from logging on outside of these hours.
2. Configure account expiration in user accounts: Another option is to set an expiration date on the user account. This can be done in the same location as the logon hours settings. By setting an expiration date that falls before the end of the three-month period, you can ensure that the user account is no longer valid after the end of their temporary employment.
3. Configure account policies in group policy: You can also use group policy to configure account policies that limit logon hours. This can be done by going to the "Account Policies" section of group policy and selecting "Logon Hours." Here, you can specify the days and times during which users are allowed to log on.
4. Configure account lockout in group policy: Finally, you can configure account lockout settings in group policy to prevent users from repeatedly attempting to log on outside of allowed hours. This can be done by going to the "Account Lockout Policy" section of group policy and specifying the number of failed logon attempts that will result in the account being locked out.

d. db.inventory.find(\{\})
Answers
Option A is the correct command that will return all items from inventory collection.
The correct command that will return all items from the inventory collection is db.inventory.find().
Option A) db.inventory.find() is the correct command that will return all the documents from the inventory collection.
It returns all the documents from a collection and does not specify any filters to find a particular document.Option B) db.inventory.findOne() will only return the first document found in the inventory collection.
It is used to find one specific document in a collection.
Option C) b.inventory.findAll() is an incorrect command as there is no method called findAll() available for collections in MongoDB.

assume the employee table has 6 records, and the department table has 4 records. the following sql statement produces
Answers
The given SQL statement produces a Cartesian product or cross join between the Employee table and the Department table, resulting in 24 records (6 records * 4 records).
A Cartesian product or cross join combines each row from one table with every row from another table, resulting in a combination of all possible pairs of rows. In the given scenario, the Employee table has 6 records, and the Department table has 4 records. When the Cartesian product is performed between these two tables, each record from the Employee table will be paired with every record from the Department table.
Since there are 6 records in the Employee table and 4 records in the Department table, the resulting Cartesian product will have a total of 6 * 4 = 24 records. Each record will represent a combination of an employee and a department.
It's important to note that Cartesian products can result in a large number of records, especially when the tables involved have a significant number of rows. Care should be taken when using Cartesian products to avoid unintended consequences and ensure that the result is as intended.

Which relational algebra expression is equivalent to the following SQL statement?

O II passenger:Name) ( TicketPrice<1000) (Booking))
Answers
The relational algebra expression equivalent to the given SQL statement "SELECT Passenger Name FROM Booking WHERE TicketPrice < 1000" is: σ(TicketPrice < 1000)(Booking) π(PassengerName)(Booking)
The σ symbol indicates the selection operator in this SQL statement, which filters the tuples of the relation "Booking" based on the criteria "TicketPrice < 1000." The resultant relation is then sent through the projection operator symbol 'π' to retrieve the "PassengerName" property from the filtered tuples.
To put it another way, the expression obtains the names of all passengers who bought a ticket for less than 1000 dollars by first picking the appropriate tuples from the "Booking" relation and then projecting just the "PassengerName" property from those tuples.
