Section 2.4 Demonstrate your acquired knowledge about Physical Installations. This will demonstrate your proficiency for section 2.4 of the Network+ 10-009 objectives. 1 / 25 Which best practice is recommended for ensuring consistent temperature in a server room? Leave server room doors open Use air curtains Use hot aisle/cold aisle containment Disable rack-mounted fans 2 / 25 Why should network equipment not be placed directly under fire suppression sprinkler heads? It improves cable routing To reduce exposure to potential water damage It reduces power consumption It's required for grounding 3 / 25 Which type of power issue can a UPS typically NOT handle for extended periods? Voltage sag Short-term outages Complete long-term blackout Power spikes 4 / 25 What’s the best location to install a patch panel in a physical installation? Directly on the floor Behind the server rack In the top of the rack for easy access Mounted within a structured wiring panel or rack 5 / 25 How can you ensure balanced power usage across multiple PDUs? Use only one phase of power Monitor and distribute loads evenly across circuits Disable redundant power supplies Avoid using fiber connections 6 / 25 What is a common risk when installing networking equipment in an environment with poor airflow? Unauthorized access Duplex mismatches Overheating and potential hardware failure Misconfigured VLANs 7 / 25 Which component protects devices from power surges and may be built into a PDU? Load balancer Circuit breaker Voltage amplifier Surge suppressor 8 / 25 What is the typical size of a standard rack unit (1U)? 1.5 inches 1.75 inches 2 inches 2.5 inches 9 / 25 How does a rack-mounted UPS differ from a standalone UPS? It only powers monitors It cannot be used in data centers It is designed to fit in standard 19-inch racks It only provides short-term power 10 / 25 Which of the following components is most likely to be installed in the MDF rather than the IDF? Floor switch Patch panel Core router Wireless access point 11 / 25 Why is cable management crucial in a rack-mounted network environment? It improves wireless signal strength It enhances data encryption It helps with airflow and simplifies troubleshooting It reduces CPU load on devices 12 / 25 What is the recommended temperature range for server rooms to prevent overheating? 90–100°F (32–38°C) 60–75°F (15–24°C) 30–40°F (0–4°C) 80–90°F (27–32°C) 13 / 25 Which type of fire suppression system is safest for sensitive electronic equipment? Water-based sprinkler system Foam-based suppression Clean agent gas system Dry powder extinguisher 14 / 25 Which environmental factor is most directly responsible for corrosion in network equipment? Heat Humidity Dust Fire suppression chemicals 15 / 25 Which unit of measurement is used to define voltage supplied to network devices? Ohms Amps Watts Volts 16 / 25 When considering the power load of a rack, what should be accounted for? Only switch consumption Total power draw of all connected devices Airflow direction Cable length 17 / 25 What is the primary purpose of a Power Distribution Unit (PDU) in a server rack? To regulate network traffic To supply AC power to multiple devices To act as a surge protector To cool the rack environment 18 / 25 Which device provides temporary power to network devices in the event of a power outage? PDU Voltage regulator UPS Surge protector 19 / 25 Why would a patch panel be placed in a lockable cabinet or enclosure? To improve cable throughput To prevent unauthorized physical access To increase bandwidth To lower power usage 20 / 25 What is the purpose of a fiber distribution panel? To amplify fiber signals To organize and manage fiber connections To convert fiber to copper To suppress signal interference 21 / 25 Which of the following devices is used to organize and route cables from the back of network equipment to endpoints? Router Patch panel UPS Modem 22 / 25 Why is understanding port-side airflow (exhaust/intake) important when installing network equipment? To improve wireless signal coverage To maintain physical access to ports To ensure proper cooling and airflow direction To prevent radio frequency interference 23 / 25 What is the standard width of most rack-mounted equipment used in network installations? 10 inches 12 inches 19 inches 24 inches 24 / 25 Which location is commonly used to connect endpoints on a specific floor to the main network? Data center MDF IDF DMZ 25 / 25 Which location is typically used as the central point of connectivity for an entire building or campus? IDF MDF Server Room Wiring Closet Your score is 0% Restart quiz Return to CompTia N+ 10-009 Objectives
