                                    We have two Excel files with organization data. One file has Organization ID and Organization Name fields, whereas the second file has Organization ID, Organization Name and Country fields. We wrote a query to retrieve the data from both files. Here’s a sample of the data retrieved:
                                    

                                    We want to ensure Organization ID field is unique. Which of the following is the ideal solution that ensures Organization ID field is unique while retaining Country data?
            
            A: Select the Organization ID and Country columns, and then click Keep Duplicates.
            B: Select the Organization ID and Country columns, and then click Remove Duplicates.
            C: Use Group BY function to group the rows by Organization ID. Specify output columns for Organization Name and Country using MAX operation.
            D: Select Organization ID column and then click Remove Duplicates. Then specify output columns for Country using MAX operation.
                                    

                                    Breed Chasing, solo engineer is planning to create new cryptocurrency, NEWCRAIGLIST and build a blockchain that facilitates buying and selling second-hand items with NEWCRAIGLIST from each other. Breed expects the platform to be used for international transactions and devised the following process:
            
            - Before a transaction is considered complete, the purchaser must put the funds in an escrow service
            - The sender must enter the courier tracking number into that same escrow
                                    

                                    Palmart, toy store giant in US is asked by lawmakers to provide evidence that proves the store’s toys are not produced through child labour. Palmart’s toys are transferred between 7 parties between creation and placement at the store. Palmart is considering using blockchain to solve this problem. Discretion in the reading and writing of transactions is highly important to the store chain to protect its proprietary interests. Review the following possible solutions and pick the best approach that solves Palmart’s problem:
                                    

                                    Option A:
            Use a public blockchain that supports assets.
            Then create a new toy asset for each item created. 
            When the toy is transferred to the next party, mandate that the associated blockchain asset to be transferred to the next party's blockchain account with required metadata.
            Lawmakers can now view transactions and transfers at any time.
            
            Option B: 
            Use a permissioned blockchain.
            Require that every party involved in the process to host a node on the Palmart's network. 
            Create a new toy asset for each item created. 
            When the toy is transferred to the next party in the process, have the previous party use a web portal to initialize a chain code Smart Contract to transfer control of the asset. 
            When the next party receives the asset have them use a web portal to initialize a chain code Smart Contracts to acknowledge receipt of the asset. 
            Provide read-only permissions to the lawmakers so they can receive the evidence they are looking for.
                                    

                                    Su is the project manager for a Bengaluru based video storage company. The allowable deviation for video compression time is ±150 milliseconds. They use a third party service which offers an API for video compression. The third party service delivers documentation with the latest version of the API which states that the requirements are being met as per specification. Su’s team conducts multiple quality tests on the API. The aggregate deviation found by her team is 155 milliseconds, but the team says this variation from the permissible deviation is negligible. What should Su do?
                                    

                                    A: Allow the API since the third party vendor provided the product on time
            B: Allow the API for now, but ask the third party vendor for an explanation
            C: Document the low level of quality, allow the API to be used and work with the third party vendor to find a solution
            D: Reject the API and ask the third party vendor to provide the product within the allowable deviation
            E: Use the API for now, and start developing their own video compression API to use in the future
            F: Halt the project and start developing their own video compression API
                                    

                                    We want to create a DAX formula in Power BI that automatically calculates the previous month number. If month is May, the formula would return 4. We have already created the DAX formula: 
                                    

                                    Today Month = MONTH (Sales[Todays Date])
                                    

                                    Which of the DAX formulas below would be the right choice next?
                                    

                                    A: Previous Month = Sales[Today Month]-1
            B: Previous Month = PREVIOUSMONTH(Sales[Today Month])
            C: Previous Month = STARTOFMONTH(Sales[Today Month])-1
            D: Previous Month = IF (Sales[Today Month] =1, 12,Sales[Today Month]-1) (correct)
