You have a company network that is connected to the internet. You want all users to have internet access, but you need to protect your private network and users. You also need to make a web server publicly available to internet users.Which solution should you use?
Answers
Answer:
Explanation:
In this scenario, the best option is to first create a DMZ. This stands for Demiliatirized Zone and basically allows anything connected to it to access networks that have not been completely verified (which in this case would be the internet). Once the DMZ is created you are going to want to add the web server to the DMZ. This will allow the web server to access the internet and be publicly available to its users. At the same time you are going to want to add the company network behind the DMZ so that it is not allowed to publicly access the internet without the data going through the firewall first. Therefore, protecting the company network users.

You require a "vulnerability scanner" to provide you with the information to be able to identify the services running on a set of servers on your network.
What is a vulnerability scanner?Vulnerability scanning, commonly known informally as 'vuln scan,' is an automated technique for finding network, application, and security problems ahead of time. The IT department of a company or a third-party security service provider often does vulnerability scanning. Attackers use this scan to find points of access to your network.
A vulnerability scanner can provide features that a port scanner cannot: sending notifications when new systems are connected to the network.
If you want to be able to identify the services running on a set of servers on your network then you need a "vulnerability scanner" to equip you with the details.

Answer:
a very very old Microsoft application that only people on old pc's use now
Explanation:
Answer:
Microsoft Excel is a Microsoft software program that allows users to organize, format, and calculates data using the formulas of a tablet.
This program is part of the Microsoft Office Suite and supports other Office Suite applications. Microsoft Excel can now be purchased on subscription via cloud via office 365, as can other Microsoft Office products.
Explanation:
In Excel, entering a value column and clicking on a cell in the low sheet below allows the cell to add all of the numbers entered above to the "auto sum" button. This takes place in the manual leader counts, which before the development of the modern table were a labor-intensive part of the business.
Microsoft Excel is also a key user technology, useful in training and professional development, in various types of simple case applications. MS Excel has been included in basic corporate computer graduation training for several years, and temporary employment agencies may examine individuals for a wide variety of clerical duties on their skills with Microsoft Word and Microsoft Excel.
The data visualization principle has changed the Microsoft Excel usage cases. Where companies have used Microsoft Excel for, say, hundreds of records in the past, most business cases today involve tablets containing less than a dozen values for each particular project.

what can be the maximum possible length of an identifier 3163 79 can be of any length
Answers
Answer:
79 characters
Explanation:
The programming language is not stated, but a little search online shows the question is about python programming language
Literally, identifiers are the names given to variables, arrays and functions.
In most programming languages (e.g. python), identifiers are case-sensitive.
i.e. Abc is a different identifier when compared to abc.
Having said that, python allows up to 79 characters to name an identifier.
Meaning that, the length of a variable name (or array, or function, etc.) can be up to 79 characters, and it cannot exceed 79 characters.

Answers
Group of answer choices.
A. It can communicate with networks inside a particular company with subnets.
B. It can communicate on the local network as well as on the Internet.
C. It has a public IP address that has been translated to a private IP address.
D. It cannot communicate outside its own network.
Answer:
D. It cannot communicate outside its own network.
Explanation:
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
Basically, a DHCP server is designed to automatically assign internet protocol (IP) address to network devices connected to its network using a preconfigured DHCP pool and port number 67.
When a computer that is configured with DHCP cannot communicate or obtain an IP address from the DHCP server, the Windows operating system (OS) of the computer automatically assigns an IP address of 169.254.33.16, which typically limits the computer to only communicate within its network.
Generally, a computer cannot communicate outside its own network when it is assigned an IP address of 169.254.33.16.

Which type of attack cripples the network and prevents legitimate users from accessing network resources
Answers
Answer:
A Distributed Denial of Service (DDoS) attack is a non-intrusive internet attack made to take down the targeted website or slow it down by flooding the network, server or application with fake traffic. When against a vulnerable resource-intensive endpoint, even a tiny amount of traffic is enough for the attack to succeed.
Distributed Denial of Service (DDoS) attacks are threats that website owners must familiarize themselves with as they are a critical piece of the security landscape. Navigating the various types of DDoS attacks can be challenging and time consuming. To help you understand what a DDoS attack is and how to prevent it, we have written the following guidelines.
1
What is a DDoS attack?
1.1 – Understanding a DDoS Attack
The objective of a DDoS attack is to prevent legitimate users from accessing your website. For a DDoS attack to be successful, the attacker needs to send more requests than the victim server can handle. Another way successful attacks occur is when the attacker sends bogus requests.
1.2 – What is the Goal Behind a DDoS Attack?
The main goal of an attacker that is leveraging a Denial of Service (DoS) attack method is to disrupt a website availability:
The website can become slow to respond to legitimate requests.
The website can be disabled entirely, making it impossible for legitimate users to access it.

GNU/GPL:
Answers
Answer:
Explanation:
copyleft:
Copyleft is the practice of granting the right to freely distribute and modify intellectual property with the requirement that the same rights be preserved in derivative works created from that property.
creative Commons:Creative Commons (CC) is an internationally active non-profit organisation that provides free licences for creators to use when making their work available to the public. These licences help the creator to give permission for others to use the work in advance under certain conditions. Every time a work is created, such as when a journal article is written or a photograph taken, that work is automatically protected by copyright. Copyright protection prevents others from using the work in certain ways, such as copying the work or putting the work online. CC licences allow the creator of the work to select how they want others to use the work. When a creator releases their work under a CC licence, members of the public know what they can and can’t do with the work. This means that they only need to seek the creator’s permission when they want to use the work in a way not permitted by the licence. The great thing is that all CC licences allow works to be used for educational purposes. As a result, teachers and students can freely copy, share and sometimes modify and remix a CC work without having to seek the permission of the creator3. GNU/GPL:GPL is the acronym for GNU's General Public License, and it's one of the most popular open source licenses. Richard Stallman created the GPL to protect the GNU software from being made proprietary. It is a specific implementation of his “copyleft” concept.
Software under the GPL may be run for all purposes, including commercial purposes and even as a tool for creating proprietary software, such as when using GPL-licensed compilers. Users or companies who distribute GPL-licensed works (e.g. software), may charge a fee for copies or give them free of charge.

They can be used to format content in a tabular manner when the markup does not use the table element, e.g. because the markup was written by someone who was told not use tables or because the markup is generic XML and not HTML.
You can also design a page using e.g. div elements so that some stylesheet formats them as a table, some other stylesheet lets them be block elements or turns them to inline elements. This may depend e.g. on the device width
