Pass SK0-005 Exam Guide

A perpetual license is a one-time purchase that allows the software to be used indefinitely without recurring costs. This meets the requirement of a non-renewing, one-time capital expense.

Perpetual (Answer D): This is a one-time purchase and does not require renewal, making it ideal for capital expenditure.

Open-source (Option A): Open-source software is usually free but may not meet specific licensing requirements.

Subscription (Option B): This typically involves recurring payments, which contradicts the non-renewing expense requirement.

Volume (Option C): Volume licenses are used for purchasing multiple licenses at a discount but may still involve subscription-based renewals.

CompTIA Server+ Reference:This topic is covered under SK0-005 Objective 2.1: Explain licensing concepts for software.

Retention policies define how long data should be kept before being archived or deleted and help in determining the frequency of backups to ensure data is available when needed. These policies are crucial for compliance, storage management, and disaster recovery planning.

Retention policies (Answer A): These directly address how long data is kept and how often it should be backed up.

Service-level agreement (Option B): SLAs define performance expectations and uptime, not specific data retention or backup schedules.

Life-cycle management (Option C): This refers to managing data from creation to disposal but doesn’t specifically address backup frequency or retention periods.

Mean time to recover (Option D): This metric measures how long it takes to restore services after a failure, not backup scheduling.

CompTIA Server+ Reference:This topic relates to SK0-005 Objective 4.2: Explain the importance of data security concepts.

RAID 10 is the best option to deploy a database server that provides the highest performance with fault tolerance. RAID 10 is a type of RAID level that combines RAID 1 (mirroring) and RAID 0 (striping) to create an array of mirrored stripes. RAID 10 offers high performance by distributing data across multiple disks in parallel (striping), which improves read/write speed and I/O operations. RAID 10 also offers fault tolerance by duplicating data across two or more disks in each stripe (mirroring), which provides redundancy and data protection in case of disk failure. RAID 10 requires at least four disks to implement and has a high storage overhead, as half of the disk space is used for mirroring. References: [CompTIA Server+ Certification Exam Objectives]

The virtual server’s time is incorrect despite proper configuration of internal time servers.

Resolution: The engineer should manually correct the time (Option D):

If the internal time servers are configured correctly, manual adjustment is necessary.

Checking firewall rules would help identify NTP (Network Time Protocol) issues.

Replacing the CMOS battery is unlikely to be the cause of incorrect time.
