Q: Which of the following should be used when installing network cabling above a drop ceiling that is part of the shared air space?

B. Plenum-rated. Plenum-rated Plenum spaces (above drop ceilings used for HVAC airflow) require plenum-rated cable because it has a fire-retardant jacket that won't release toxic fumes if it burns. Regular PVC cable is a fire code violation in these spaces. Shielded twisted pair, optical, and coaxial cables are not automatically plenum-rated — they must specifically be rated for plenum use.

Q: While using a computer, a user reports that the system fan begins running loudly and the display starts to distort. Which of the following is occurring?

A. Overheating. Overheating A loud fan running at high speed is the cooling system working overtime to dissipate excess heat. Display distortion under heat is a symptom of GPU or CPU overheating. Sluggish performance and application crashes are secondary effects. Overclocking is a configuration choice, not a symptom. The combination of loud fan + visual artifacts specifically points to thermal overload.

Q: Which of the following is a common feature of managed switches?

B. Port VLAN assignment. Port VLAN assignment Managed switches allow per-port VLAN configuration, giving network administrators logical segmentation control. Remote power delivery (PoE) is a hardware feature, not exclusive to managed switches. Content filtering is done by firewalls or proxies. Load balancing is handled by dedicated load balancers or routers, not switches.

Q: Which of the following is a characteristic of Type 2 hypervisors?

B. Need for an underlying OS. Need for an underlying OS A Type 2 hypervisor (e.g., VMware Workstation, VirtualBox) runs on top of an existing host operating system. It requires that OS to function. Type 1 (bare-metal) hypervisors install directly on hardware with no host OS. Local management only and specific hardware requirements are not defining characteristics of Type 2 hypervisors.

Q: Which of the following port numbers is used for a file transfer?

A. 21. 21 Port 21 is used by FTP (File Transfer Protocol) for control/command communication. Port 53 is DNS. Port 68 is DHCP client. Port 389 is LDAP. For the exam, memorize: FTP = 21 (control) and 20 (data).
