CompTIA Server+ SK0-005 Updated Exam

A server has multiple fans inside the chassis to cool down the components and prevent overheating. If one of the fans fails, it can cause the server to reboot and crash due to thermal issues. A failed fan can also make loud noises due to friction or vibration. The administrator should check the fans and clean them from dust and debris, or replace them if they are damaged12.

Leaving a USB drive in a company parking lot is a classic example of social engineering, where the bad actor relies on human curiosity to prompt someone to pick up the USB drive and insert it into their computer, potentially infecting the system with malicious code.

Social engineering (Answer D): The attacker manipulates human behavior (in this case, curiosity) to exploit security weaknesses.

Hacking (Option A): Hacking refers to directly breaching security systems or exploiting software vulnerabilities, not manipulating humans.

Insider threat (Option B): This involves a legitimate insider within the organization carrying out malicious activities, which isn’t the case here.

Phishing (Option C): Phishing typically involves emails or messages designed to deceive individuals into providing sensitive information.

CompTIA Server+ Reference:This topic is covered under SK0-005 Objective 4.2: Explain server security concepts and best practices.

A 1000BASE-LX 1Gb single-mode plenum fiber connection would best meet the analyst’s needs for a new point-to-point Ethernet connection between a university campus and a newly acquired space downtown that is about 5mi (8km) away. A 1000BASE-LX is a type of Ethernet standard that supports data transmission at 1 gigabit per second over single-mode fiber cables using long wavelength lasers. 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 plenum fiber cable is a type of optical fiber cable that has a special coating that prevents the spread of fire or toxic fumes in case of burning. A plenum fiber cable is suitable for installation in plenum spaces, which are areas used for air circulation in buildings, such as above ceilings or below floors. References: [CompTIA Server+ Certification Exam Objectives], Domain 4.0: Networking, Objective 4.2: Given a scenario involving server networking issues (e.g., network interface card failure), troubleshoot using appropriate tools.

Off-site storage involves storing data backups in a physically separate location from where the servers and primary data reside. This protects critical data in case the main site is damaged or destroyed due to a natural disaster, such as floods, fires, or earthquakes. Off-site storage can be in the form of cloud storage or physical tapes stored in a geographically distant location.

Off-site storage (Answer A): It ensures that a company's critical data remains accessible even if the local infrastructure is compromised. This is a common part of disaster recovery planning and is crucial for business continuity.

Life-cycle management (Option B): While important for managing data from creation to deletion, it does not specifically protect data during disasters.

Environmental controls (Option C): These manage physical conditions like temperature and humidity but do not address the risk of data loss during disasters.

Data-at-rest encryption (Option D): Encryption protects the confidentiality of stored data but does not ensure availability in the event of a disaster.
