CompTIA Network+ Certification Exam 認定 N10-009 試験問題 (Q542-Q547):

質問 # 542
Which of the following physical installation factors is the most important when a network switch is installed in a sealed enclosure?

正解：B

解説：
Switches in sealed enclosures are at risk of overheating because airflow is restricted. The temperature factor is critical since heat buildup can damage components, shorten device lifespan, and cause outages. Proper cooling or ventilation must be ensured.


質問 # 543
Two network switches at different locations are connected via fiber-optic cable at a distance of 10 miles (16 km). The duplex fiber-optic patch cord between the patch panel and switch is accidentally pinched, stopping connectivity between the two switches. A network technician replaces the broken cable with a new, single-mode patch cord. However, connectivity between both switches is still down and the link lights are still off. Which of the following actions should the technician perform first?

正解：A

解説：
Fiber connections require Tx on one end to connect to Rx on the other end. If the patch cord is replaced and link lights remain off, the most common cause is that the connectors are reversed.
Swapping (transposing) the connectors ensures proper transmit/receive alignment.


質問 # 544
Which of the following should be used to obtain remote access to a network appliance that has failed to start up properly?

正解：C

解説：
If a network appliance fails to start, standard remote access methods like SSH won't work.
Instead, Out-of-Band (OOB) management provides a dedicated access path (e.g., a console port or iDRAC/iLO), allowing administrators to troubleshoot devices even when the network is down.


質問 # 545
Users report that they cannot print to a specific IPv4-enabled printer after an extended power outage. Which of the following should a technician configure?

正解：C

解説：
A DHCP reservation ensures the printer consistently receives the same IPv4 address after power loss or reboot, allowing users' print connections to keep pointing to the correct device.


質問 # 546
Which of the following standards enables the use of an enterprise authentication for network access control?

正解：A

解説：
Comprehensive and Detailed Explanation (aligned to N10-009):
802.1X provides port-based Network Access Control (NAC), requiring authentication (often through RADIUS) before granting access. This is the standard for enterprise authentication on both wired and wireless networks.
A . 802.1Q defines VLAN trunking.
C . 802.3bt defines higher-power PoE.
D . 802.11h deals with spectrum management in wireless.
