CompTIA Server+ SK0-005 Syllabus Exam Questions Answers

The solution that is used for failover, providing access to all the services currently in use by an organization without having to physically move any servers or employees, is the cloud. The cloud is a term that refers to a network of remote servers that are hosted on the Internet and provide various services, such as storage, computing, networking, and applications. The cloud can be used for failover, which is a backup operation that automatically switches to a standby system or service in case of a failure or disruption of the primary system or service. By using the cloud for failover, an organization can ensure continuous availability and accessibility of its services without requiring any physical relocation or intervention.

These are two measures that should be taken when a data breach occurs. A data breach is an unauthorized or illegal access to confidential or sensitive data by an internal or external actor. A data breach can result in financial losses, reputational damage, legal liabilities, and regulatory penalties for the affected organization. Disclosing the incident is a measure that involves informing the relevant stakeholders, such as customers, employees, partners, regulators, and law enforcement, about the nature, scope, and impact of the data breach. Disclosing the incident can help to mitigate the negative consequences of the data breach, comply with legal obligations, and restore trust and confidence. Identifying the exploited vulnerability is a measure that involves investigating and analyzing the root cause and source of the data breach. Identifying the exploited vulnerability can help to prevent further data loss, remediate the security gaps, and improve the security posture of the organization. Restoring the data from backup is a measure that involves recovering the lost or corrupted data from a secondary storage device or location. However, this does not address the underlying issue of how the data breach occurred or prevent future breaches. Disabling unnecessary ports is a measure that involves closing or blocking network communication endpoints that are not required for legitimate purposes. However, this does not address how the data breach occurred or what vulnerability was exploited. Running an antivirus scan is a measure that involves detecting and removing malicious software from a system or network. However, this does not address how the data breach occurred or what vulnerability was exploited. Moving the data to a different location is a measure that involves transferring the data to another storage device or location that may be more secure or less accessible. However, this does not address how the data breach occurred or what vulnerability was exploited. References: ht

A cache battery is a battery that provides backup power to the cache memory of a disk array controller. The cache memory stores data that is waiting to be written to the disk array. If the cache battery fails, the data in the cache memory may be lost or corrupted when the power is interrupted. Verified References: [Cache battery], [Disk array controller]

The backup type that only records changes to the data blocks on a virtual machine is snapshot. A snapshot is a point-in-time copy of a virtual machine (VM) that captures the state and data of the VM at a specific moment. A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the VM after the snapshot was taken. A snapshot can be used to restore the VM to its previous state in case of data loss or corruption.
