Answer:
There Should be at least 10 Points
Explanation:
An execution graph becomes more powerful as you add more data points because there will be more opportunities to identify patterns. If you are looking for signs of improvement, you usually need at least 10 data points.
Performance charts (frequently acknowledged as line graphs outside the excellence management field) display the performance of the process over time
I beleive all of the above for question one
<span>There are several reasons why two devices are not synchronized: maybe there are not the same versions of the programs on both devices, maybe the software needs restart in order to have the latest input data, maybe the internet connection was lost during synchronization
Next steps would be:
- restart the devices
- Update to the latest version
- connect to the internet
- make the synchronization again

Answer: (C) MAC
Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
On the other hand, all the options are incorrect as they are not the key dependent hash function.
Therefore, Option (C) is correct.
