you are creating a new vm in hyper-v and you want the vm to be able to perform a secure boot. what option do you need to choose when configuring the vm?
The guest can use BitLocker to encrypt the virtual machine disk by configuring the encryption support settings in Hyper-V Manager. By accessing the VM settings, we may enable this.
We can use the capability known as nested virtualization to run Hyper-V inside of a Hyper-V virtual machine (VM). This is useful for testing configurations that typically call for several hosts or running a Visual Studio phone emulator in a virtual machine. The use of nested virtualization is supported both on-premises and on Azure. Virtual switches in Hyper-V can be external, internal, or private. To share our computer's network with the virtual machines that are operating on it, create an external switch.

The option that you need to configure so that the site can be accessed with the hostname is option A: Forward lookup zone
How do forward DNS lookups function?When a user writes in a web page URL or email address in text form, Forward DNS operates. First, a DNS server receives this message. Following a record check, the DNS server returns the domain's IP address. The DNS server sends the request to a different server if it is unable to find the domain's IP address.
Reverse lookup zones translate IP addresses into names while forward lookup zones translate names into IP addresses. On your DNS server, forwarders can be used to forward requests for which your DNS server lacks an authoritative response.
Therefore, Note that Forward DNS lookup is said to often make use of an Internet domain name to be able to see an an IP address.

An abstract class is a class that has been explicitly designated as such; it may or may not contain abstract methods. Although abstract classes cannot be created, they can be subclassed. Whenever an abstract class is subclassed, the parent class's abstract methods are typically implemented by the subclass. If you want to give all component implementations a common, implemented feature, you use an abstract class. When compared to interfaces, abstract classes allow you to partially implement your class while interfaces would have no implementation at all for any of the members. An abstraction that makes it simple to add more vehicles is, for instance, a Vehicle parent class from which Truck and Motorbike inherit.

timmy is a new employee at an organization and was given a laptop. upon connecting the laptop to the local wi-fi network, he receives an ip address of 192.168.58.127 but is not able to connect to the internet. what could be the problem? quizlet
Since Timmy upon connecting the laptop to the local wi-fi network, he receives an ip address of 192.168.58.127 but is not able to connect to the internet the problem could be It could be service provider or the wifi as well as the router itself. It can also be the fact that access has been restricted or passworded.
What is local network on Wi-Fi?A local area network (LAN) is a network that is said to bve made up of a number of computers that are connected in a certain area. TCP/IP ethernet or Wi-Fi is used in a LAN to link the computers to one another.
For two or a lot of devices, a wireless local area network (WLAN) is seen as a form of wireless distribution technique. WLANs employ high-frequency radio waves and frequently have an Internet access point built in. Users of a WLAN can move across the coverage area, which is frequently a house or small business, while still remaining connected to the network.
Therefore, Wi-Fi enables devices to connect to one another similarly to how network cables function, only without the need for physical cords. In essence, a Wi-Fi network is a wireless local network.

Identity some basic security threats and solutions for all network
Answer:install anti virus software ensure that software Is up to date ,filter all emails traffic nd users tk be careful of suspicious emails
don't run any unkhown user's origin development of information security policy report the unauthorized situation
Top security threats include unauthorized access, eavesdropping, IP address spoofing, man-in-the-middle attacks, brute force attacks, and browser attacks.
1. Unauthorized Access - Leakage of confidential information and other attacks can be exacerbated. Attackers unknowingly gain access to authorized areas to steal sensitive resources.
Implement strong authentication policies. Keep your username and password secret from untrusted sources. Don't give users or employees unnecessary access.
2. Eavesdropping - It is another significant cybersecurity risk. In eavesdropping, an intruder intercepts packets of data sent over HTTP (via monitoring software), modifies the data, and exploits it to damage the network.
Solution: An interesting encryption strategy protects against eavesdropping. Encryption methods such as electronic certificates (SSL certificates) reduce the risk of eavesdropping.
Enforce network segmentation to prevent eavesdropping and other network attacks.
Network Access Control improves network security by verifying the authenticity of each device before establishing a connection.
3. IP spoofing: IP address - Spoofing creates the illusion of a valid IP address by obtaining her IP address on a network and generating internet protocol packets with the intent to compromise the owner's actual IP address increase.
Solution: Filtering incoming packets on the network is one way to prevent spoofing. On the other hand, we also need to filter incoming and outgoing traffic.
Access control lists help prevent identity theft by discouraging people from entering bogus IP addresses.
Encrypted credentials should be provided so that only trusted servers can communicate.
To further reduce the risk of identity theft, you should use an SSL certificate.
4. Man-in-the-middle attack - MITM is one of the most dangerous cyber threats. Here the intruder establishes an independent connection with the sender and receiver, intercepts the messages one by one, modifies these messages, and forwards them to the sender and receiver.
Solution: Use Public Key Infrastructure (PKI) based authentication. It not only protects your application from eavesdropping and other attacks, but it also verifies that your application is trusted.
Both ends are authenticated to prevent (MITM) man-in-the-middle attacks. Configure passwords and other top-level secrets for better mutual authentication.
Suppose the time it takes for a message to reach the end is 20 seconds. If the total execution time exceeds 60 seconds, the existence of an attacker is proven.
5. Brute force attack - A brute force attack is performed to guess the maximum combination of passwords. Use passwords with complicated symbols, numbers, and letters and keep them saved.

the operation of verifying that the individual (or process) is who they claim to be is known as? complete mediation access control authentication verification
The operation of verifying that the process or individual is who they claim to be is known as authentication. Thus, the correct option to this question is an option (C) i.e. authentication.
Authentication is an operation that is commonly used in computer language or in software engineering to verify the person or process what they ought to be. Authentication operation verifies that the person, individual, or process accessing the system is the authenticated individual, person, or user.
While the other options are incorrect because:
The term complete mediation is used to check that access to the object is allowed. While access control is a measure to control access to the system by an unauthenticated process or user. Whereas, the verification verifies that the user or process is original.
The complete question is given below

A protocol for network communication enables basic data transfers between network devices. A network protocol is a set of rules that have been designed to control how data is moved between different devices connected to the same network.
A network protocol is a set of rules that have been designed to control how data is moved between different devices connected to the same network. Essentially, it makes it possible for connected devices to communicate with one another regardless of differences in their internal workings, organizational systems, or aesthetics. Due to their ability to enable global communication, network protocols are crucial to modern digital communications. Network protocols break down large-scale operations into smaller, more specialized jobs or functions, each component within Network protocol.
