Selected SK0-005 CompTIA Server+ Questions Answers

A hot site with private cloud backup is the most suitable for environments that require continuous access to critical data, like student data containing PII. A hot site is fully operational and ready to take over immediately in case of a disaster. Using a private cloud provides more control and security, which is important when handling sensitive data like PII.

Hot site with private cloud backup (Answer D): This ensures minimal downtime and robust security, which is critical for handling PII.

Warm site (Options A & B): A warm site has some infrastructure ready but requires some setup before becoming operational, which introduces some delay.

Cold site (Option C): A cold site has the least preparation and requires significant time to become operational, which would not meet the requirement for constant availability.

Scope-based authentication is a method of restricting access to resources based on the location, network, or device of the user. It can be used to prevent unauthorized access from outside the organization’s network or from untrusted devices. In this case, the user can connect to the database server from the home office, which is likely within the scope of the authentication policy, but not from the hotel room, which is outside the scope.

A warm site is a backup site that has some of the necessary hardware, software, and network resources to resume operations, but not all of them. A warm site requires some time and effort to become fully operational. A warm site is different from a cold site, which has minimal or no resources, and a hot site, which has all the resources and is ready to take over immediately.

The most likely issue that prevents the newly added server from seeing any of the LUNs on the SAN is that a single-mode fiber cable is used in place of multimode. A single-mode fiber cable is a type of optical fiber cable that has a small core diameter and allows only one mode of light to propagate through it. A single-mode fiber cable can transmit data over long distances at high speeds, but it requires more expensive transceivers and connectors than multimode fiber cables. A multimode fiber cable is a type of optical fiber cable that has a larger core diameter and allows multiple modes of light to propagate through it. A multimode fiber cable can transmit data over short distances at lower speeds than single-mode fiber cables, but it is more compatible and cost-effective than single-mode fiber cables. If a single-mode fiber cable is used in place of multimode, it can cause signal loss, attenuation, or mismatch between the devices. References: [CompTIA Server+ Certification Exam Objectives], Domain 3.0: Storage, Objective 3.2: Given a scenario, compare and contrast various storage technologies.
