Which identifier should the technician record?

A field technician is installing a new IP-based security camera in a remote warehouse corner. The camera requires Power over Ethernet (PoE) to operate, but the existing network switch supplying the Ethernet drop does not support PoE functionality. Budget constraints prevent replacing or adding a new PoE-capable switch. Which network hardware device should the technician install inline between the switch port and the camera to provide the necessary electrical power over the Category 6 cabling?

A network technician is configuring firewall rules to allow a centralized monitoring server to poll system status and hardware performance metrics from managed network switches using Simple Network Management Protocol (SNMP). Which of the following transport protocol ports must be permitted through the firewall?

During a post-installation survey of a retail facility's 2.4 GHz wireless infrastructure, a systems specialist discovers high frame retry rates caused by adjacent-channel interference. The site survey reveals that three neighboring access points are currently operating on channels 2, 5, and 8 with a 20 MHz channel width. Which channel configuration plan should the specialist implement to ensure that all three access points operate without adjacent-channel overlap?

A system administrator needs to configure a network printer so that it automatically receives the exact same IPv4 address every time it boots up, without manually configuring a static IP address on the printer itself. Which of the following should the administrator configure on the network server?

A system administrator is auditing physical media and peripheral connections in a corporate IT department. Match each cable or connector type on the left with its primary physical characteristic or use case on the right.

A systems administrator notices that several workstation computers in a newly established branch office fail to authenticate to the enterprise domain controller. Further inspection reveals that the system clocks on the affected workstations differ by more than six minutes from the domain controller clock, breaking time-sensitive authentication protocols. Which network server role should be configured to automatically synchronize local clocks across all host devices on the network?

A network architect is designing a 10 Gbps backbone connection between two distribution facilities on an industrial campus. The cable run measures 450 meters (1,476 feet) in length and must pass directly through an active air handling plenum space that contains high-voltage manufacturing equipment generating extreme electromagnetic interference (EMI). Which of the following cable types and fire-safety ratings must be selected to fulfill all bandwidth, distance, security, and environmental safety specifications?

A field technician is sorting hardware inventory for an infrastructure upgrade. Match each network or peripheral cable and connector type on the left to its corresponding primary application or characteristic on the right.

A network technician is troubleshooting a connectivity issue where workstations on Subnet A (192.168.10.0/24) cannot communicate with workstations on Subnet B (192.168.20.0/24). Both subnets are physically connected to ports on the same network device. The technician observes that the device forwards traffic strictly using MAC address tables and does not perform logical IP packet routing. Which network hardware device is currently installed, and what device should be used to enable communication between the subnets?

A field technician is servicing a high-performance laptop brought in for repair due to an unlit display. The user reports that after a minor drop, the built-in screen went dark, although status LEDs remain active and connecting an external monitor displays the operating system normally. Upon disassembling the screen bezel, the technician verifies that the laptop is equipped with an Organic Light-Emitting Diode (OLED) panel. A junior technician assisting with the repair suggests ordering a replacement inverter board to fix the backlight power supply. Which of the following statements best evaluates the junior technician's recommendation?

A field technician is deploying a third wireless access point (AP3) to extend coverage across a warehouse floor. Existing access points AP1 and AP2 are operating on 2.4 GHz Channel 1 and Channel 6, respectively, both using 20 MHz channel widths. To eliminate adjacent-channel interference while ensuring maximum stability for legacy and modern 2.4 GHz wireless clients, which channel number and channel width configuration must be applied to AP3?

A network technician is documenting network topology characteristics and cable termination requirements for a company upgrade. Match each network topology classification to the physical or logical behavior that accurately defines its operation.

A field technician is deploying a new desktop workstation in an office environment and needs to connect the computer's network interface card to a standard twisted-pair Ethernet wall port. Which connector type should be terminated on the Ethernet patch cable?

A network administrator is configuring secure mobile email client settings and troubleshooting wireless network connectivity for company-issued smartphones. Users report that when connected to the corporate guest Wi-Fi network, their mail applications fail to send outgoing messages and their devices display an IP address of 169.254.11.45. Which of the following actions should the administrator perform to resolve these issues? (Select TWO.)

A network field technician is tasked with wiring an expansion link from an automated industrial manufacturing floor—known for severe electromagnetic interference (EMI) from heavy machinery—to a network switch situated inside a ceiling return air plenum space. Concurrently, the technician must establish a direct serial connection from an out-of-band management appliance to a legacy router's dedicated serial console port. Which of the following cabling standards, jack types, and outer jacket ratings must the technician deploy to meet all technical and safety requirements? (Select TWO.)

A PC technician is sizing a power supply unit (PSU) and placing expansion cards for a high-performance workstation. The system components have the following peak power requirements:

- CPU: $140\text{ W}$
- Discrete Graphics Card (GPU): $280\text{ W}$
- PCIe x4 RAID Controller Card: $25\text{ W}$
- System RAM, Storage Drives, and Cooling Fans: $60\text{ W}$

The motherboard features two physical PCIe x16 expansion slots: Slot 1 is connected directly to 16 CPU lanes, while Slot 2 is wired to 4 chipset lanes. To ensure system stability and longevity, the total peak power draw must not exceed $80\%$ of the PSU's rated continuous wattage capacity.

Which of the following combinations correctly identifies the minimum standard PSU wattage rating required and the optimal expansion slot installation for the RAID controller?

An IT technician is auditing corporate mobile synchronization technologies and security controls for a fleet of enterprise mobile devices. Match each mobile synchronization method or security feature on the left with its corresponding enterprise capability or requirement on the right.

A network administrator is designing a structured cabling deployment for a commercial facility with two specific installation requirements:

1. A 250-meter interconnect between two distribution closets that passes near high-voltage electrical conduits.
2. Horizontal cable runs routed above a drop ceiling in an environmental air plenum space.

Which TWO of the following cabling types or jacket ratings must the administrator specify to meet these deployment requirements correctly? (Select TWO.)

A network technician is installing a high-density 10GBASE-T Ethernet link between two core distribution switches located 75 meters (246 feet) apart in an industrial facility. The cable path must pass directly alongside heavy electrical machinery and high-voltage power conduits. Which cable category and physical construction must be specified to maintain 10 Gbps throughput across this distance while mitigating potential data corruption from electromagnetic interference?
