Correct answers: Test and replace failing CMOS batteries; Configure reliable NTP servers for time synchronization

Replacing failing CMOS batteries resolves the root cause of time loss during power fluctuations. The CMOS battery maintains system time and BIOS settings when main power is lost. Even with UPS protection, if the CMOS battery is weak or failing, the system will lose time during brief power interruptions. This hardware-level fix ensures the real-time clock continues operating during power events.

Configuring reliable NTP (Network Time Protocol) servers ensures accurate time synchronization across all workstations. NTP servers provide authoritative time sources that automatically correct system clocks even after power events. This addresses the automatic time synchronization configuration mentioned in the scenario and provides a permanent network-based solution that works independently of local hardware issues.

Correct answer: DHCP reservation binding

DHCP reservation binding (also called DHCP reservation) permanently assigns a specific IP address to a device based on its MAC address. This ensures the network printer will always receive the same IP address from the DHCP server, even when the DHCP address pool is depleted or exhausted. The reservation operates outside the normal dynamic allocation process, guaranteeing the device gets its assigned IP address regardless of pool availability. This is the most reliable method for ensuring critical network devices maintain consistent IP addressing in dynamic DHCP environments.

Correct answer: 6 GHz band for dedicated high-throughput connections

The 6 GHz band is the correct choice for maximizing throughput while minimizing interference. Wi-Fi 6E extends Wi-Fi 6 into the 6 GHz spectrum, providing up to 1200 MHz of additional spectrum, seven 160 MHz channels, and no legacy device interference. This band is exclusively for Wi-Fi 6E devices, ensuring optimal performance without competition from older devices or neighboring networks using traditional bands.

Correct answer: NTP service for time synchronization

Network Time Protocol (NTP) is the correct service to configure for resolving time synchronization issues. NTP synchronizes computer clocks across networks by connecting to authoritative time sources. In a domain environment, servers should sync with domain controllers or designated NTP servers to maintain accurate timestamps, which are critical for authentication, logging, and scheduled tasks. Port 123/UDP is used for NTP communication.

Correct answer: Mini-LED for excellent contrast without burn-in

Mini-LED is the best choice for this scenario. Mini-LED technology uses thousands of tiny LEDs for backlighting, enabling precise local dimming zones that deliver exceptional contrast ratios and near-OLED black levels without the burn-in risk associated with OLED displays. This makes Mini-LED ideal for professional graphic design where static elements might remain on screen for extended periods. Mini-LED also offers high brightness levels and excellent HDR performance.

Correct answer: Type 1 bare-metal hypervisor

Type 1 (bare-metal) hypervisor is correct for this scenario. Type 1 hypervisors run directly on the physical hardware without needing a host OS, providing better performance, security isolation, and lower latency compared to Type 2 hypervisors. Examples include VMware ESXi, Microsoft Hyper-V Server, and Citrix XenServer. This architecture eliminates the overhead of a host OS and provides direct hardware access for optimal VM performance.

Correct answer: Use one physical SIM and activate one eSIM profile

Using one physical SIM and one eSIM profile is the best configuration for dual-carrier support. eSIM (embedded SIM) is a programmable chip built into the device that can be activated remotely using a QR code or carrier app. This dual-SIM configuration allows simultaneous use of two carriers without requiring two physical SIM slots, enabling separate personal and business lines on one device with easy profile management.

Correct answer: Containers with shared kernel

Containers are the ideal solution for this requirement. Containers package applications with their dependencies into portable units that share the host OS kernel, making them much lighter than VMs. Technologies like Docker create isolated environments without the overhead of full operating systems, enabling consistent deployment across development, testing, and production environments. Containers start faster, use fewer resources, and provide the portability needed for modern DevOps workflows.

Correct answer: Virtual Desktop Infrastructure (VDI)

Virtual Desktop Infrastructure (VDI) is the correct solution for providing centrally managed remote desktops. VDI hosts desktop environments on centralized servers in the data center, allowing users to access their desktops from any device through thin clients or web browsers. This ensures all data remains secure in the corporate data center, simplifies management and updates, provides consistent user experience across devices, and enables better security control and compliance.

Correct answer: Check and replace thermal paste on CPU

Checking and replacing the thermal paste is the next logical step. When thermal paste degrades or dries out, it loses its ability to efficiently transfer heat from the CPU to the heat sink, causing overheating even with clear vents and working fans. Symptoms include high temperatures, maximum fan speeds, and thermal shutdowns. Reapplying quality thermal paste often resolves persistent overheating issues when external airflow is not the problem.
