An online retailer would like to add capacity to support increased sales. Additional servers have been installed. Which of the following should be used to ensure each new server is being properly utilized?
A. Virtualization
B. Clustering
C. Load balancer
D. Round-robin DNS
Explanation: https://www.resonatenetworks.com/2020/04/29/clustering-vs-load-balancingwhats-
the-difference/
A load balancer distributes network traffic evenly across multiple servers, ensuring each
server is being properly utilized. This helps to prevent overloading of any individual server,
which can cause downtime or slow response times for users. In this scenario, adding a
load balancer would be the best way to ensure the new servers are being properly utilized.

A small office has a wireless network with several access points for roaming laptop use. Users occasionally report that the wireless connection drops or becomes very slow. Users have confirmed that this issue only happens when connected to the office wireless network. Which of the following would MOST likely be the cause?
A. Hidden SSID
B. Device interference
C. Ethernet port flapping
D. High ISP latency
Explanation: Device interference is the most likely cause of the wireless connection dropping or becoming slow. Interference can come from other wireless devices, microwave ovens, or physical barriers like walls and metal objects. Hidden SSID, Ethernet port flapping, and high ISP latency are not likely to cause this issue. Wireless interference from other devices can cause a drop in wireless connection speed and stability. In a small office environment, there may be several wireless devices competing for the same bandwidth, causing the issues described.

This troubleshooting step aligns with the CompTIA A+ Core 1 objective regarding maintaining printers for optimal performance.
A laptop PC user is reporting issues with the hard drive. A filesystem check shows that all files are accessible and the filesystem is clean. After the check, the PC still issues a hard drive error message. Which of the following is the MOST likely cause of the error?
A. S.M.A.R.T failure
B. IOPS failure
C. DIMM failure
D. RAID failure
Explanation: If the filesystem check shows that all files are accessible and the filesystem is clean, but a hard drive error message persists, it's possible that the hard drive is experiencing S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) failure. This is a warning system built into hard drives to alert users of potential issues before they become critical.
A technician is monitoring all outbound traffic in a SOHO. Which of the following is the MOST cost-effective solution to monitor the traffic?
A. Spectrum analyzer
B. Network tap
C. Lookback plug
