A code ("EIG AUC REO RAI COG") was sent to the criminal office by a CID agent named Batra.  However, four of the five words are fake, with only one containing the information. They also included a clue in the form of a sentence: "If I tell you any character of the code word, you will be able to tell how many vowels there are in the code word." Are you able to figure out what the code word is?

A: RAI 
                        B: EIG
                        C: AUC
                        D: REO
                        E: COG
                        F: None

In a new code language called Adira, 
                        
                        - '4A, 2B, 9C' means 'truth is eternal'
                        - '9C, 2B, 8G, 3F' means 'hatred is not eternal'
                        - '4A, 5T, 3F, 1X' means 'truth does not change'
                        
                        What is the code for 'hatred' in Adira?

Alex’s uncle is a magician who gave them a magic bag in which coins get doubled each time you put those coins into it. Initially, Alex had few coins with them. So, Alex put all the coins, and the coins got doubled. Alex took out all the coins and gave a few to their friend and then again put the remaining coins back in the bag. The coins doubled again; Alex took out all the coins again and gave a few coins to their second friend. Alex then put the remaining coins in the bag and the coins doubled again. Alex took out all the coins and gave a few coins to their third friend. 

There were no coins left with Alex when Alex gave coins to the third friend and Alex gave an equal number of coins to each friend. What is the minimum number of coins Alex had initially and how much did Alex give to each friend?

A pharmaceutical company claims that their new drug, Xylanex, is highly effective in treating a specific medical condition. They provide statistical data from a clinical trial to support their claim. However, a group of scientists has raised concerns about the validity of the study design and potential bias in the data collection process. They argue that the results may be inflated and not truly representative of the drug's effectiveness.
                        
                        Which of the following assumptions is necessary to support the pharmaceutical company's claim?

A: The clinical trial participants were randomly selected and representative of the target population.
                        B: The scientists raising concerns have a conflict of interest and are biased against the pharmaceutical company.
                        C: The statistical analysis of the clinical trial data was conducted by independent experts.
                        D: The medical condition being treated by Xylanex is widespread and affects a large number of individuals.
                        E: The pharmaceutical company has a proven track record of developing effective drugs for similar medical conditions.

What does the following Java code output?

Review the following React code:

Pick the correct statements:
                        
                        A: The code renders 10 INDIAN RUPEE
                        B: The code renders 10 SINGAPORE DOLLAR
                        C: The code does not render anything and throws an error since JavaScript objects are not valid as React children
                        D: When the currency portion is clicked, the parent component is re-rendered
                        E: When the currency portion is clicked, parent component will skip the re-render because shouldComponentUpdate returns false
                        F: Parent component can be converted to a functional component with memoization (useMemo or memo) to avoid the re-render

You work as a Solutions Architect for a data analysis firm. The company stores large datasets on Amazon S3, and you've been tasked with setting up an Amazon EC2 instance to process this data. The EC2 instance will fetch data from S3, process it, and then write the results back to a different S3 bucket.
                        
                        To ensure security, the EC2 instance should not have direct internet access, and it should only be able to communicate with the S3 buckets. You've decided to place the EC2 instance in a VPC private subnet with a CIDR block of 10.0.1.0/24. The associated security group is set to deny all inbound traffic and allow all outbound traffic.
                        
                        Which additional configuration should you make to enable the EC2 instance to access the S3 buckets while complying with the security requirements?

A: Modify the Network ACL of the subnet to allow outbound connections to the IP range of the S3 service.
                        B: Assign a Public IP to the EC2 instance and update the security group to allow inbound and outbound traffic to S3.
                        C: Add a NAT Gateway in the private subnet and update the route tables to direct S3 traffic to the NAT Gateway.
                        D: Create an S3 VPC Gateway Endpoint and update the route tables for the private subnet to direct S3 traffic to the VPC Endpoint.
                        E: Create a VPN connection from the VPC to the S3 buckets.

A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. 

Example:
                        
                        Input:
                        WWMMWWCCC
                        
                        Expected Output: 
                        4W3C2M
                        
                        Explanation: 
                        ‘W’ has the highest count, then ‘C’, then ‘M’. 

⚠️⚠️⚠️ Note:
                        - The input is already parsed and passed to a function.
                        - You need to "print" the final result (not return it) to pass the test cases.
                        - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’.
                        - If any of them have the same count, the output should follow this order - M, W, C.

Consider the following two tables in Power BI:

We received the following error when we tried to set many-to-one cardinality between devices to users tables: “The cardinality you selected isn’t valid for this relationship”. What should we do before creating the many-to-one relationship?
