That sounds great, @Eugene! If you find the video, definitely share it with me—I'd love to check it out for reference. In the meantime, I can start drafting the step-by-step guide and include some examples for using OpenSSL in the command prompt to verify certificates and protocols. Once I have a draft, we can go over it together and refine it. We can also brainstorm on how best to format the guide or video for everyone. Looking forward to collaborating on this

Thanks for the suggestion @Eugene! I think creating a step-by-step guide or even recording a video on using the command prompt for OpenSSL and TLS certificate verification would be a great way to help everyone learn more effectively. It would cover verifying certificates, checking protocol versions, and ensuring secure connections. We could collaborate on this or You/I can put together a draft and we can refine it together. Let me know what you think!

I think could be a great idea, I was looking for a particular video I watched to so I could share it but will have to hunt for it.

SSL they say because people are familiar with that term but I agree should just call it TLS 1.3 on everything instead of saying it is SSL when it is not. I inform my classes about those kind of things.

I tell my classes that SSL was deprecated in June 2015, but they may still find references to it.

Is a new A+ Cert needed to train?

Eugene
Dan said:
I know this is a necrobump, but A+ has changed quite a bit since 1999...

Would I ask a prospective instructor to take the entire course again? absolutely not! In fact, if an employer told me to take an entire A+ course, just to teach a course for that employer, I'd tell them thanks but no thanks, and withdraw my application.

the TTT would be nice, but that wouldn't be something I mandated... but it should be in the resources I profile him)

What I would do is require any new instructor to hold a current cert for the course they are going to teach (and GFL and ce certs are not the same). I'd provide the voucher so he wouldn't have to buy it himself, but no one should be teaching a course unless they have passed that exam. When I started in my current role, my director told me I needed to take the ITF exam to teach the course. I have ~20 years in IT... and passed the exam

here is my perspective: if he has 20 years of experience, and he is up to date on his knowledge, then he should have no issues passing the exam.

If he can't, do I really want him teaching a course for an exam that he couldn't pass?

Sounds like a company I was working for. They make you take ever cert over and over again and try to make the Train-the-Train mandatory which is why I pretty much left. Cost to much to get and they started going down hill anyway so I look for companies that accept me for what I can do for students.

For Precious maybe could link up and go through some commands some time or some. I would like to show more using the command prompt in verify those kinds of things.

What is a database schema?

A type of data storage device
A programming language
A type of software
The architecture of how a database is structured and organized

Explanation​

Click to expand...
A database schema is the architecture of how a database is structured and organized. It defines the tables, fields, relationships, views, indexes, and other elements within the database. A schema serves as a blueprint that outlines how data is stored, how it can be accessed, and how different data entities relate to each other.

What is the purpose of forms in a database?
To reduce data entry errors
To create new tables
To change database settings
To delete records

Explanation​

Click to expand...
The purpose of forms in a database is to reduce data entry errors. Forms provide a user-friendly interface for inputting data, ensuring that users enter information in a structured and consistent manner. By using forms, databases can enforce data validation rules, guiding users to input correct and complete information, which helps minimize errors during data entry

Which type of data is best stored in a relational database?

Random data
Structured data
Semi-structured data
Non-structured data

Explanation​

Click to expand...
The type of data best stored in a relational database is structured data. Relational databases are designed to handle data that fits neatly into tables with predefined schemas, making it easy to enforce data integrity and perform complex queries using SQL. Structured data typically includes numbers, dates, and fixed-length strings, which can be organized into rows and columns

What does a relationship in a database do?

Connects two entities
Stores data
Deletes data
Creates a new database

Explanation​

Click to expand...
A relationship in a database connects two entities. It links data between tables based on common fields, such as primary and foreign keys. This allows the database to associate related information across different tables, enabling more complex queries and better organization of data.

What is non-structured data?
Data that is always numerical
Data that fits neatly into rows and columns
Correct Answer:
Data that doesn't have a clear order or pattern
Data that is always textual

Explanation​

Click to expand...
Non-structured data is data that doesn't have a clear order or pattern. Unlike structured data, which is organized into rows and columns (like in relational databases), non-structured data can include various forms such as text, images, videos, emails, and more. This type of data doesn't follow a predefined format or schema, making it more flexible but also more challenging to store and analyze.

How does a document database store data?
In rows and columns
In word documents
In spreadsheets
In flexible documents

Explanation​

Click to expand...
A document database stores data in flexible documents. These documents are typically in formats like JSON, BSON, or XML, and can hold complex, nested data structures. Unlike relational databases that use rows and columns, document databases store data as key-value pairs within documents, allowing each document to have a unique structure. This flexibility makes document databases suitable for handling unstructured or semi-structured data.

What does NoSQL stand for?

New SQL
No SQL Allowed
Incorrect answer:
Non-Structured Query Language
Correct Answer:
Not Only SQL

Explanation​

Click to expand...
A foreign key is a primary key from another table. It is a column or set of columns in a relational database table that creates a link between data in two tables. The foreign key in one table refers to the primary key in another table, establishing a relationship between the tables and enforcing referential integrity. This ensures that the data in the foreign key column must match a value in the related table's primary key.

What is a relational database?
A database that stores data in a single table.
A database that only stores text data
A database that keeps data in several connected tables.
A database that does not use tables at all.

Explanation​

Click to expand...
A relational database is a database that keeps data in several connected tables. These tables are structured with rows and columns, and they use relationships (often through keys, such as primary keys and foreign keys) to connect data across different tables. This structure allows for efficient organization, retrieval, and manipulation of data, and it supports complex queries involving multiple tables

Correct Answer:
Not Only SQL

Explanation​

Click to expand...
NoSQL stands for "Not Only SQL." It refers to a class of database management systems that are designed to handle unstructured or semi-structured data and can scale easily with large datasets. NoSQL databases do not rely solely on the traditional relational database structure, which uses tables and rows, but can support various data models such as document, key-value, graph, and columnar formats. This makes them ideal for handling big data, real-time web applications, and distributed architectures.
