End-of-life is the phase of lifecycle management that deals with a server that is no longer in operation. End-of-life means that the server has reached the end of its useful life and is no longer supported by the manufacturer or the service provider. End-of-life may also imply that the serveris obsolete, incompatible, or inefficient for the current needs and standards1. End-of-life servers may be decommissioned, recycled, donated, or disposed of according to the organizational policies and environmental regulations

RAID 10 is the RAID level that will yield the best combination of available space and redundancy when configuring a new server for use as a database server with two mirrored drives for the operating system and three drive bays remaining for storage. RAID 10, also known as RAID 1+0, is a RAID configuration that combines disk mirroring and disk striping to protect data. It requires a minimum of four disks and stripes data across mirrored pairs. As long as one disk in each mirrored pair is functional, data can be retrieved. RAID 10 provides high performance, fault tolerance, and fast recovery, but it reduces storage capacity by half. RAID 0 is a RAID configuration that splits data across two or more drives without parity or redundancy. It improves performance but offers no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 1 is a RAID configuration that duplicatesdata across two or more drives. It provides fault tolerance and improves read performance, but reduces storage capacity by half. If one drive fails in RAID 1, the other drive can continue to operate without data loss or system downtime. RAID 5 is a RAID configuration that stripes data across three or more drives with parity information. It provides fault tolerance and improves performance, but reduces storage capacity by one drive’s worth of space. RAID 5 can tolerate one drive failure without data loss, but not two or more.

A S.M.A.R.T. error is an indication of a potential failure of a hard drive. S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology and it is a feature that monitors the health and performance of hard drives. A hard drive test can help diagnose the issue and determine if the drive needs to be replaced.References: https://www.comptia.org/training/resources/exam-objectives/comptia-server-sk0-005-exam-objectives (Objective 1.1)

Something you have is one of the types of authentication methods that relies on a physical object or device that the user possesses to verify their identity. A token is an example of something you have, as it is a small device that generates a one-time password or code that the user enters during login. A token can be a hardware device, such as a key fob or a smart card, or a software application, such as an app on a smartphone or a browser extension. A token provides an additional layer ofsecurity to theauthentication process, as it prevents unauthorized access even if the user’s username and password are compromised1.

Disposal is the part of the asset life cycle that can cause the greatest number of issues in relation to PII exposure. PII stands for personally identifiable information, which is any data that can be used to identify a specific individual, such as name, address, phone number, email, social security number, etc. PII exposure is the unauthorized access or disclosure of PII, which can result in identity theft, fraud, or other harms to the individuals whose data is compromised. Disposal is the process of getting rid of an asset that is no longer needed or useful, such as a server, a hard drive, or a mobile device. If the disposal is not done properly, the PII stored on the asset may still be accessible or recoverable by unauthorized parties, such as hackers, thieves, or competitors. Therefore, it is important to follow best practices for secure disposal of assets that contain PII, such as wiping, encrypting, shredding, or physically destroying the data storage media

Password length is the first password policy that the administrator should implement to help mitigate the chance of a successful brute-force attack. A brute-force attack is a method of guessing passwords by trying all possible combinations of characters untilthe correct one is found. The longer the password, the more combinations there are, and the more time and resources it takes to crack it. Therefore, password length is a key factor in password strength and security.

Round robin is a load balancing technique that distributes requests among multiple web nodes in a circular order. It ensures that each web node receives an equal amount of requests and improves the availability and performance of the web application. Verified References: [Round robin], [Load balancing]

Fibre Channel is a connectivity option that can transmit at 16Gb over an optical connection for SAN-based shared storage. Fibre Channel is a high-speed network technology that provides reliable and secure data transfer betweenservers and storage devices. Fibre Channel uses optical fiber cables to connect devices and supports various topologies and protocols. FCoE is another connectivity option that uses Fibre Channel over Ethernet, which encapsulates Fibre Channel frames into Ethernet packets. FCoE can also transmit at 16Gb over an optical connection, but it requires a converged network adapter (CNA) and a lossless Ethernet network. iSCSI is another connectivity option that uses SCSI commands over IP networks, which can use either copper or optical cables. iSCSI can transmit at 10Gb or 40Gb over an optical connection, but it has higher latency and lower performance than Fibre Channel. eSATA is another connectivity option that uses SATA commands over external cables, which are usually copper. eSATA can transmit at 6Gb over a copper connection, but it has limited cable length and device support compared to Fibre Channel.
