CompTIA SK0-005 Online Access

The most likely reason for this result is that there is a manual entry in the hosts file that maps the FQDN to an incorrect IP address (104.18.17.32). The hosts file is a text file that contains mappings of hostnames or domain names to IP addresses, which are used by the operating system to resolve names before querying DNS servers on the network or internet. The hosts file can be used to override DNS settings or block access to certain websites by redirecting them to different IP addresses, such as localhost (127.O.O.l) or invalid addresses (O.O.O.O). If there is a manual entry in the hosts file that conflicts with DNS records, it can cause name resolution errors or connectivity issues. References: [CompTIA Server+ Certification Exam Objectives], Domain 4.0: Networking, Objective 4.l: Given a scenario, configure network settings for servers.

Scenario: Four disks, requiring redundancy and maximum usable capacity.

RAID Level: RAID 10 (Option D) is the best choice:

RAID 10 combines mirroring (redundancy) and striping (performance).

RAID 0 lacks redundancy, RAID 1 provides less capacity, and RAID 5 requires more

The storage type that will yield the fastest database read performance is SSD. SSD (Solid State Drive) is a type of storage device that uses flash memory to store data. SSDs have no moving parts and can access data faster than traditional hard disk drives (HDDs) that use spinning platters and magnetic heads. SSDs are especially suitable for databases that are mainly used for archival lookups, as they can provide faster response times and lower latency for read operations.

Recovery Time Objective (RTO) refers to the target time set for the recovery of IT and business activities after a disaster has struck, which includes restoring server, network, and data access. The policy requirement mentioned in the question aligns with the definition of RTO, as it specifies the maximum allowable downtime or the time within which functionality must be restored. Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR) are metrics related to the reliability and repair times of systems but do not specifically pertain to disaster recovery time frames. Recovery Point Objective (RPO) describes the acceptable amount of data loss measured in time, not the restoration of operations.
