1. Right Answer: D
Explanation: MTRJ can be used with both SMF and MMF fiber.
2. Right Answer: D
Explanation: SATA specifications and hardware permit only one device on each SATA cable. Multiple cable connections are available on the SATA controller for expansion.
3. Right Answer: D
Explanation: The SATA 3 interface operates at 6 Gbps however the interface supports up to 600 MB/s (Megabytes per second) throughput.
4. Right Answer: B
Explanation: Operation in the UNII bands automatically makes 802.11a devices incompatible with all other devices complying with the other 802.11 series of standards. The reason for this incompatibility is simple: systems using 5-GHz frequencies do not communicate with systems using 2.4 -GHz frequencies.
5. Right Answer: A
Explanation: Another idea in implementing security for wireless LAN segments is to create a wireless demilitarized zone (WDMZ). Depending on the level of implementation, creating WDMZs using firewalls or routers can be costly. WDMZs are generally implemented in medium- and large-scale wireless LAN deployments. Because access points are basically insecure and untrusted devices, they should be separated from other network segments by a firewall device.
