Answer:
1. DHCP may be blocked by a firewall software
2. Static IP assigned to the workstation
Explanation:
DHCP refers to the The Dynamic Host Configuration Protocol (DHCP) it is used to automatically assign IP addresses to every device on a computer network. Through the DHCP server, computers request IP addresses as well as other parameters for the network needed for communication, and directly obtain them from the internet service provider (ISP). If this service is block by a firewall software it could be a reason why the workstation is unable to connect to the network. Configuring a static IP address rather than allowing automatic assignment of IP addresses could also lead to this problem

Write code that creates another set containing all the elements of set1 and set2, and assigns the resulting set to the variable set3.
Answer:
The code to this question as follows:
set3= set1.difference(set2)
Explanation:
In the above python code, we assume that 3 sets are defined that are "set1, set2, and set3". In which two sets set1 and set3 must include some values. and set3 include code that is "set1.difference(set2)".
In this code, the set3 includes set1, set2 and use an inbuilt function that is the difference(). This function is used to define the difference between set1 and set2 and store values in set3. To know the difference we print set3.Final answer:
To combine all elements of set1 and set2 into set3, use the union operation in Python with either 'set3 = set1 | set2' or 'set3 = set1.union(set2)'.
Explanation:
To create a set that contains all elements from both set1 and set2, and assign it to set3, you use the union operation in set theory. In Python, this operation can be performed using the | operator or the union() method on sets. Here's how you can do it:
set3 = set1 | set2
or alternatively,
set3 = set1.union(set2)
Both lines of code will result in set3 containing all unique elements from set1 and set2, as per the definition of union operation in set theory.

You can create an absolute cell reference by placing a ____ in front of both the column letter and the row number of the cell address.
Answer:
Dollar sign ($)
Explanation:
When working with formulas in microsoft excel, we may find ourselves copying formulas accross different cells, this is done by cell referencing and there two types of cell references, the absolute and relative. An absolute reference to a cell simply means that the cell is "locked" and its rows and columns are not going to change when they are copied. So when an absolute referenced formula is copied to another cell, it remains constant. This is unlike the relative reference where the formula changes relative to the new location where it is copied to. To accomplish an absolute reference, the dollar sign ($) is placed in the front of both the letter and number representing the column and row respectively like this $A$5.
An absolute cell reference in Excel can be created by placing a $ symbol before both the column letter and the row number of the cell address, such as $A$1.
Explanation:In Excel, you can create an absolute cell reference by placing a $ symbol in front of both the column letter and the row number of the cell address. For example, if you would like to make cell A1 an absolute reference, you would write it as $A$1. This means that no matter where you copy and paste this formula, it will always refer to cell A1. The use of $ keeps the reference constant, or 'absolute).

Electronic informed consent forms (eICFs) are increasing in popularity and offer many benefits to the researcher.
What are the benefits of eICFs to the researcher?
Answer:
Reduces the chances of error by making sure that there are no missed section.
Explanation:
Electronic informed consent forms (eICFs) are web and mobile phone based technology used to collect required data needed by hospital or medical facility, for consent to medical trier, surgery etc. It is patient friendly and easy to used.
The traditional paper based consent form process is inefficient and increase the chance of patient dropout, giving them lesser information they need to be convinced.
eICF gives the clients adequate information and makes certain necessary section required using web based coding, which can only submit the form if it is filled as required.
Final answer:
eICFs benefit researchers by streamlining the consent process, enhancing data security and privacy, supporting compliance with IRBs, and allowing quick updates to consent documentation.
Explanation:
The benefits of electronic informed consent forms (eICFs) to the researcher are numerous. Firstly, eICFs streamline the consent process by providing an efficient way to distribute, complete, and store consent forms, which is beneficial for both researchers and participants. This can lead to higher response rates and a more organized documentation process. Secondly, eICFs enhance data security and privacy because electronic systems can use secure encryption methods to protect personal information.
Thirdly, they support compliance with institutional review boards (IRBs) by ensuring that all necessary information is presented to participants clearly and effectively, facilitating better understanding and adherence to ethical standards. Lastly, the use of eICFs allows for quick updates and revisions to consent documentation, which is essential in dynamic research environments where changes might be frequent.

Sharon is responsible for the security on web applications. She’s looking to see if all applications have input validation. What is the best way to implement validation?
Answer:
Options Include:
A) Server-side validation
B) Client-side validation
C) Validate in trust
D) Client-side and server-side validation
Client-side and server-side validation is Correct
Explanation:
The best option is to validate the client side with the server side. Using these together would provide the best testing option for Sharon.
This keeps user feedback instantly without wasting postbacks while also protecting against JavaScript disabled users. That's how the validation controls for ASP.NET operate.
This is definitely not over-engineering as there are risks of using one without the other.
Individual validation on the server side and individual validation on the client side are both incorrect. Trust validation is not a form of validation.

ACL 1 has three statements, in the following order, with address and wildcard mask values as follows: 1.0.0.0 0.255.255.255, 1.1.0.0 0.0.255.255, and 1.1.1.0 0.0.0.255. If a router tried to match a packet sourced from IP address 1.1.1.1 using this ACL, which ACL statement does a router consider the packet to have matched?
If a router tried to match a packet sourced from IP address 1.1.1.1 using this ACL, the first statement will be used.
a. First
Explanation:
We use ACL technology to make basic security level in the network. ACL is strictly used to update the routing in the network and make sure network pears and make sure the flow control for network traffic is followed.
Since it is routing ip address through ACL statement. It all depends on how the network engineer routed the traffic in the network. A packet with source IP address 1.1.1.1 would match any of the three explicitly configured commands described in the question. As a result, the first statement will be used.
The router searches the ACL statement by order and when the match is found it stops execution of the ACL statement that will match with the first occurrence.

Mesh networks:
a. usually provide relatively long routes through the network (compared to ring networks)
b. require more processing by each computer in the network than in star or ring networks
c. do not use decentralized routing
d. do not have much capacity wasted by network status information
e. do not have many possible routes through the network to prevent one circuit from becoming overloaded
Answer:
B) Require more processing by each computer in the network than in star and ring networks
Explanation:
Meshnet which refers to mesh networks is one of the topologies of computer networks. In this topology, the nodes are all connected directly to each other and to as many many other nodes that cooperate with each other (nodes here refers to PCs, bridges routers etc), this kind of connection prevents dependence on a single node for communication as all nodes participates in the passing of information, as a result each computer in a mesh requires more processing work than in star and ring networks.
Imagine that you have configured the enable secret command, followed by the enable password command, from the console. You log out of the switch and log back in at the console. Which command defines the password that you had to enter to access privileged mode?
a. enable password
b. enable secret
c. Neither
d. The password command, if it's configured
Answer:
b. Enable Secret
Explanation: Enable secret command is used to enable a secret password for a particular privilege level. It encrypts the desired password for entering the privileged executive mode of a router or switch. This encryption restrains the password from being saved in clear text format in configuration file contrary to enable password which is stored in plain text. Enable secret defines additional layer of security over the enable password. It is based on MD5 hash algorithm. If both enable secret and enable password commands are configured, then enable secret outranks and overrides the enable password. Internetwork Operating System will only acknowledge the password as configured in the enable secret command. When you set a password using enable secret command, a password set using the enable password command only works if enable secret is disabled or you are using older version of Cisco IOS software.
