Grandfather-father-son (GFS) is a common backup rotation scheme that uses daily, weekly, and monthly backup media in a first-in, first-out (FIFO) method. The daily backups are rotated on a 3-months basis using a FIFO system as above. The weekly backups are similarly rotated on a bi-yearly basis, and the monthly backups are rotated on an annual basis. The oldest backup media in each cycle are overwritten by the newest ones. This scheme provides multiple versions of backup data at different intervals, allowing for flexible restoration options. Waterfall is another name for GFS. Synthetic full is a backup method that combines an initial full backup with subsequent incremental backups to create a new full backup without transferring all data again. Tower of Hanoi is another backup rotation scheme that uses an algorithm based on moving disks between three pegs. References:

A DHCP reservation is a way to assign a specific IP address to a device based on its MAC address, which is a unique identifier for each network interface card (NIC). When the administrator replaced the NIC, the MAC address of the server changed, and the DHCP server no longer recognized it as the same device. Therefore, the DHCP server assigned a different IP address to the server, which was incorrect for the application. To fix this problem, the administrator needs to modify the DHCP reservation to use the new MAC address of the NIC, so that the server can get the proper IP address.

A WWNN (World Wide Node Name) is a unique identifier for a Fibre Channel node, which is a device that can communicate over a Fibre Channel network. A WWNN is not related to DHCP or IP addresses, and it is not used for DHCP reservations. Therefore, options B and D are incorrect.

Updating the local hosts file with the correct IP address (option C) is also incorrect, because it does not solve the problem of getting the correct IP address from the DHCP server. The hosts file is a local file that maps hostnames to IP addresses, and it is used to override DNS queries. However, it does not affect how the DHCP server assigns IP addresses to devices. Moreover, updating the hosts file manually on every device that needs to communicate with the server is not a scalable or efficient solution.

netstat is a command-line tool that displays network connections, routing tables, interface statistics, and more. The -a option shows all listening and non-listening sockets on the server. This can help check the open ports on a server and identify any unwanted or malicious

The user has likely fallen victim to a phishing scam, which is a fraudulent attempt to obtain sensitive information, such as passwords, by disguising as a legitimate entity. The link in the email that required the user to change the account password was probably a fake website that mimicked the company’s external database, and captured the user’s credentials when they entered them. This could compromise the security and integrity of the company’s data, as well as the user’s identity and privacy12.

The company should take immediate action to prevent further damage and investigate the incident. The first step is to disable the user’s account and inform the security team. Disabling the user’s account can prevent unauthorized access to the external database by the attackers, who may use the stolen credentials to log in and manipulate or steal data. Informing the security team can alert them of the breach and allow them to take appropriate measures, such as scanning for malware, changingpasswords, notifying other users, and reporting the incident34.
