Q232. A company in a large building uses a wireless network for its workstations. After a new company moves into the building on the floor below, the old company’s wireless network begins experiencing connectivity Issues.
Which of the following is the most likely cause?

External interference

Port flapping

High latency

Limited connectivity

Explanation
The most likely cause of the wireless network connectivity issues is A. External interference.
External interference is any signal or noise that disrupts or degrades the quality of a wireless network. External interference can come from various sources, such as other wireless networks, cordless phones, microwaves, Bluetooth devices, or electrical appliances. External interference can affect the wireless network performance, reliability, and security, by causing issues such as signal loss, packet drops, latency, or interference.
In this scenario, a company in a large building uses a wireless network for its workstations. After a new company moves into the building on the floor below, the old company’s wireless network begins experiencing connectivity issues. This could indicate that the new company’s wireless network is using the same or overlapping frequency channel as the old company’s wireless network, and creating external interference.
Wireless networks use radio frequency channels to transmit and receive data, and each channel has a certain bandwidth and range. If two or more wireless networks use the same or overlapping channel, they may interfere with each other and cause congestion or collision.
To resolve this issue, the old company’s network technician should change the wireless network channel to a different one that is less crowded or more compatible with the wireless network standard. The technician should also check the wireless network settings and features, such as SSID (Service Set Identifier), encryption, authentication, or power level, and adjust them if necessary. The technician should also scan the wireless environment and identify the sources and levels of external interference, and try to avoid or minimize them if possible.
For more information about external interference and how to prevent or reduce it, you can refer to the following web search results: [What Is Wireless Interference?], [How to Find the Best WiFi Channel for Your Router], [How to Reduce Wireless Interference].

Q247. A team is having issues with paper jams on a printer that the team shares with other teams. The team that is having issues prints legal-sized documents, and the other teams print letter-sized documents. Which of the following is most likely the issue?

Worn rollers

Page orientation

Tray settings

Multipage misfeed

Explanation
The most likely issue is C. Tray settings.
Tray settings are the configuration options that tell the printer what size and type of paper is loaded in each tray. If the tray settings do not match the actual paper size and type, the printer may not be able to feed the paper correctly and cause paper jams.
In this scenario, the team that is having issues prints legal-sized documents, which are 8.5 x 14 inches, while the other teams print letter-sized documents, which are 8.5 x 11 inches. If the printer’s tray settings are set to letter size by default, the printer may not recognize the legal-sized paper and try to pull it as if it were letter-sized paper. This can result in paper jams or misaligned printing.
To fix this issue, the team should check and adjust the tray settings on the printer to match the paper size and type they are using. They can also use a separate tray for legal-sized paper and another tray for letter-sized paper, and make sure to select the correct tray when printing.
The other options are less likely to cause the issue, because:
*Worn rollers are the rubber parts that grip and move the paper through the printer. They can wear out over time and lose their traction, causing paper jams or misfeeds. However, worn rollers would affect all teams and all paper sizes, not just one team and one paper size.
*Page orientation is the direction of the paper, either portrait or landscape. It can affect how the document is printed on the paper, but not how the paper is fed into the printer. Page orientation can be changed in the print settings or in the document itself, but it would not cause paper jams unless the paper size is also incorrect.
*Multipage misfeed is when more than one sheet of paper is pulled into the printer at once, causing a jam. This can happen if the paper is too thin, too thick, or too slippery, or if there is too much or too little paper in the tray. However, multipage misfeed would also affect all teams and all paper sizes, not just one team and one paper size.

Q248. A user contacted the help desk about files that disappeared from a laptop. The technician discovered during troubleshooting that the drive was corrupt due to a possible mechanical failure, but the files were still readable. Which of the following actions did the technician take during troubleshooting?
(Select two).

Checked S.M.A.R.T. information

Made sure the replacement drive was compatible

Ran CHKDSK

Reseated the HDD connector

Increased the page file size

Updated the firmware

M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) is a feature of hard drives that monitors various parameters, such as temperature, error rate, spin-up time, and seek time, to assess the health and performance of the drive. S.M.A.R.T. can also predict the likelihood of failure based on the historical trends of these parameters. A technician can check the S.M.A.R.T. information of a hard drive using various tools, such as the BIOS, the operating system, or third-party software. Checking the S.M.A.R.T. information can help the technician diagnose the cause and severity of the drive corruption and determine the best course of action.
