why SSTF disk scheduling is not practically feasible?
Answers
Answer:
There is a lack of predictability because of the high variance of response time. Additionally, SSTF may cause starvation of some requests. Starvation is possible for some requests as it favors easy to reach requests and ignores the far-away processes.
SSTF disk scheduling is not practically feasible because it makes an external call and is forced to wait for I/O to complete, thereby giving up its first-place position.
What is SSTF disk scheduling?Shortest Seek Time First (SSTF) is a disc scheduling algorithm that is abbreviated as SSTF. Before moving the head away to service other requests, it selects the request that is closest to the current head location.
Because of the high variance in response time, there is a lack of predictability. Furthermore, SSTF may cause some requests to be denied. Some requests may experience starvation because the system prioritizes nearby requests and overlooks distant operations.
Therefore, because it makes an external call and is obliged to wait for I/O to complete, SSTF disc scheduling is not viable because it loses its first-place status.

While troubleshooting an Internet connection problem for your network, you restarted the modem and then the router.

Explanation:
A router can be defined as a network device that is designed typically for forwarding data packets between two or more networks based on a well-defined routing protocol.
Basically, it is an electrical device or node that is designed to connect two (2) different networks (in different locations) together and allows them to communicate.
Generally, routers are configured using a standard routing protocol with an IP address as the default gateway.
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.
On a related note, 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.

Company A has a project plan for a new product under development. The product will be one of many released in the coming year. The plan, if disclosed, might give Company A's competition a market advantage. Which ISO 27002 classification level is most likely assigned to this document?
a) Public Documents
b) Proprietary
c) Highly Confidential
d) Top Secret
Answers
Answer:
Company A
The ISO 27002 classification level that is most likely assigned to this document is:
b) Proprietary
Explanation:
The ISO 27002 classification levels adopted by commercial organizations are Restricted (top secret is preferred in government circles), Confidential, Internal (or proprietary), and Public. Since the new product is under development, one of many, and most likely known to the project team, the project plan will be classified as Proprietary. Company A designates this document as Proprietary or Internal to show that disclosure of the information to its competitors is not allowed. This level of classification shows that Company A can establish intellectual property rights over the document.

a. Upload a separate list of users and passwords with a batch import.
b. Distribute hardware tokens to the users for authentication to the cloud
c. Implement SAML with the organization's server acting as the identity provider.
d. Configure a RADIUS federation between the organization and the cloud provider
Answers
Answer:
The BEST way for the organization to integrate with the cloud application is:
c. Implement SAML with the organization's server acting as the identity provider.
Explanation:
Implementing SAML (Security Assertion Markup Language) integrations will provide more security to the organization (identity provider) as users' credentials are exposed to fewer parties. SAML authenticates the users to the cloud application provider. SAML enables the organization to pass authorization credentials to the service provider by transferring the users' identities to the service provider.

Of the 4 options, which is the most secured?
WPA was created as a solution to the vulnerabilities in WEP/WEP2. Then, WPA was upgraded to WPA2.
WPA2 is the least vulnerable to hacks because for every user that is connected to the network through WPA2, a unique encryption is made available for such connection.
Hence, the most secure connection, of the 4 is WPA2.

D. Use a password manager with complex passwords
Answers
Answer:
Hence the answer is Option A Encrypt all communication with TLS 1 3.
Explanation:
Transportation Layer Security (TLS 1 3)---->TLS stands for Transport Layer Security and is the successor to SSL (Secure Sockets Layer). TLS provides secure communication between web browsers and servers. The connection itself is secure because symmetric cryptography is used to encrypt the transmitted data.
SNMPv3 Security with 256 bit AES encryption is not available for all devices. The net-snmp agent does not support AES256 with SNMPv3.so it is not the correct option.
The best choice is an option a because TLS 1 3 because,
TLS version 1 3 helped in removing all the insecure features such as:
SHA-1
RC4
DES
3DES
AES-CBC

A hierarchy chart can be helpful for a. planning the functions of a program b. naming the functions of a program c. showing how the functions of a program relate to each other d. all of the above e. a and c only
Answers
Answer:
Hence the correct options are option B and option C.
Explanation:
Hierarchy Chart means top to bottom structure 0f a function or a program or an organization.
Planning the functions of a program means deciding beforehand that what are the functions of a program and what to try to do and when to try to, hierarchy Charts are often helpful In doing/knowing this all.
Showing how the functions of a program relate to every other means what's the connection between two functions for instance if we have a hierarchical chart of a corporation member then we'll have the connection among the members of the team i.e., first, we'll have CEO, then Manager then team/ project lead then team members and by using hierarchical chart ready to " we will be able to identify the connection among them. during a similar way, we will have a relationship among the functions of a program using the hierarchical chart.

Answers
Answer:
8
Explanation:
Queues can be implemented using linear arrays; such that when items are added or removed from the queue, the queue repositions its front and rear elements.
The value of the REAR after adding 3 elements is 5
Given that:
[tex]REAR = 5[/tex] --- the rear value
[tex]n = 20[/tex] --- size of array
[tex]Elements = 3[/tex] --- number of elements to be added
When 3 elements are added, the position of the REAR element will move 3 elements backward.
However, the value of the REAR element will remain unchanged because the new elements that are added will only change the positioning of the REAR element and not the value of the REAR element.

Bluetooth and NFC (Near Field Communication) are wireless technologies that enable the exchange of data between different devices. Bluetooth operates on wavelength. NFC operates on high frequency. The security of NFC over Bluetooth makes it a better tool of choice. NFC also operates on a shorter range than Bluetooth, enabling a more stable connection. NFC also enjoys a shorter set-up time than Bluetooth. It also functions better than Bluetooth in crowded areas. Tethering requires the use of physical connectors. Infrared is not a connecting technology but wave radiation.
