• Question 503:

  Which of the following protocols supports fast roaming between networks?

  A. WEP

  B. WPA

  C. WPA2

  D. LEAP

  E. PEAP

  Correct Answer: C

  WPA2 is the only protocol among the options that supports fast roaming between networks. Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), enables a client device to roam quickly in environments implementing WPA2

  Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another1. WEP, WPA, LEAP, and PEAP do not support fast roaming and require the

  client device to perform the full authentication process every time it roams, which can cause delays and interruptions in the network service.

• Question 504:

  A technician has verified a computer is infected with malware. The technician isolates the system and updates the anti-malware software. Which of the following should the technician do next?

  A. Run one scan and schedule future scans.

  B. Back up the uninfected files and reimage the computer.

  C. Restore the clean backup copies of the infected files.

  D. Run repeated remediation scans until the malware is removed.

  Correct Answer: D

  Malware is malicious software that can cause damage or harm to a computer system or network4. A technician has verified a computer is infected with malware by observing unusual behavior, such as slow performance, pop-ups, or unwanted ads. The technician isolates the system and updates the anti-malware software to prevent further infection or spread of the malware. The next step is to run repeated remediation scans until the malware is removed. A remediation scan is a scan that detects and removes malware from the system. Running one scan may not be enough to remove all traces of malware, as some malware may hide or regenerate itself.

• Question 505:

  A user's antivirus software reports an infection that it is unable to remove. Which of the following is the most appropriate way to remediate the issue?

  A. Disable System Restore.

  B. Utilize a Linux live disc.

  C. Quarantine the infected system.

  D. Update the anti-malware.

  Correct Answer: C

  Quarantining the infected system is the most appropriate way to remediate the issue of an infection that the antivirus software cannot remove. Quarantining means isolating the system from the network and other devices to prevent the infection from spreading or causing further damage. Quarantining also allows the technician to perform further analysis and removal of the infection without risking the security of other systems or data. Some of the steps involved in quarantining an infected system are: Disconnect the system from the internet and any local network connections, such as Wi-Fi, Ethernet, Bluetooth, or USB. Disable any file-sharing or remote access services on the system, such as Windows File Sharing, Remote Desktop, or TeamViewer. Use a separate device to download and update the antivirus software and any other tools that may be needed to remove the infection, such as malware scanners, rootkit removers, or bootable rescue disks. Transfer the updated antivirus software and tools to the infected system using a removable media, such as a CD, DVD, or USB flash drive. Scan the removable media for any infections before and after using it on the infected system. Run the antivirus software and tools on the infected system and follow the instructions to delete or quarantine the infection. If the infection is persistent or complex, it may require booting the system from a rescue disk or using a Linux live disc to access and clean the system files. After the infection is removed, restore the system to a previous clean state using System Restore, backup, or recovery partition. Scan the system again to ensure that it is clean and secure. Reconnect the system to the network and update the system and the antivirus software.

  A. Place the customer on hold until the customer calms down.

  B. Disconnect the call to avoid a confrontation.

  C. Wait until the customer is done speaking and offer assistance.

  D. Escalate the issue to a supervisor.

  Correct Answer: C

  The best way to deal with an angry customer who is yelling at a technician is to wait until the customer is done speaking and offer assistance. This shows respect, empathy, and professionalism, and allows the technician to understand the

  customer's problem and find a solution. According to the CompTIA A+ Core 2 (220-1102) Certification Study Guide1, some of the steps to handle angry customers are:

  Stay calm and do not take it personally.

  Listen actively and acknowledge the customer's feelings.

  Apologize sincerely and offer to help. Restate the customer's issue and ask for clarification if needed. Explain the possible causes and solutions for the problem. Provide clear and realistic expectations for the resolution. Follow up with the customer until the issue is resolved. The other options are not appropriate ways to deal with angry customers, as they may worsen the situation or damage the customer relationship. Placing the customer on hold may make them feel ignored or dismissed. Disconnecting the call may make them feel disrespected or abandoned. Escalating the issue to a supervisor may make them feel frustrated or powerless, unless the technician cannot resolve the issue or the customer requests to speak to a supervisor.

• Question 508:

  A Linux technician needs a filesystem type that meets the following requirements:

  All changes are tracked.

  The possibility of file corruption is reduced.

  Data recovery is easy.

  Which of the following filesystem types best meets these requirements?

  A. ext3

  B. FAT32

  C. exFAT

  D. NTFS

  Correct Answer: A

  The ext3 file system is a Linux native file system that meets the requirements of the question.

  It has the following features:

  All changes are tracked. The ext3 file system uses a journaling mechanism that records all changes to the file system metadata in a special log called the journal before applying them to the actual file system. This ensures that the file system

  can be restored to a consistent state in case of a power failure or system crash12. The possibility of file corruption is reduced. The journaling feature of ext3 also reduces the possibility of file corruption, as it avoids the need for a full file

  system check after an unclean shutdown. The file system can be quickly replayed from the journal and any inconsistencies can be fixed12. Data recovery is easy. The ext3 file system supports undeletion of files using tools such as ext3grep

  or extundelete, which can scan the file system for deleted inodes and attempt to recover the data blocks associated with them34.

  A. To determine which party had the machine and when.

  B. To remotely wipe sensitive data from the machine.

  C. To gather the information needed to replace the machine.

  D. To alert the owner that the password needs to be changed.

  Correct Answer: A

  Chain of custody documentation is a record of the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. It is important to maintain a chain of custody to ensure the integrity and authenticity of the evidence, and to prevent tampering or contamination. If a laptop that was in the evidence room of a police station is missing, the best reason to refer to chain of custody documentation is to determine which party had the machine and when. This can help to identify the possible suspects, locate the missing laptop, and verify if the evidence on the laptop was compromised or not

• Question 510:

  A user's laptop has been performing slowly and redirecting to unfamiliar websites. The user has also noticed random pop-up windows. Which of the following is the first step a technician should take to resolve the issue?

  A. Scan for malware and ransomware.

  B. Perform a system restore.

  C. Check the network utilization.

  D. Update the antivirus software.

  Correct Answer: A

  The most likely cause of the user's laptop issues is that it has been infected by some type of malware or ransomware. Malware and ransomware are malicious software that can harm, exploit, or disrupt devices or networks12. They can cause symptoms such as slow performance, browser redirects, pop-up windows, data encryption, or ransom demands12. Therefore, the first step a technician should take to resolve the issue is to scan the laptop for malware and ransomware using a reliable and updated anti- malware tool34. This can help identify and remove any malicious software that may be present on the laptop. Scanning for malware and ransomware is more effective and urgent than the other options because: Performing a system restore may not remove the malware or ransomware, as some of them can persist or hide in the system files or backup copies34. Moreover, a system restore may result in data loss or corruption, as it restores the system to a previous state and deletes any changes made after that point5. Checking the network utilization may not help diagnose or fix the problem, as the malware or ransomware may not be using the network at all, or may be using it in a stealthy or encrypted manner34. Furthermore, checking the network utilization does not address the root cause of the issue, which is the presence of malicious software on the laptop. Updating the antivirus software may not be sufficient to detect or remove the malware or ransomware, as some of them may evade or disable the antivirus software, or may be too new or unknown for the antivirus software to recognize34. Additionally, updating the antivirus software does not guarantee that the laptop will be scanned for malware or ransomware, as the user may need to initiate or schedule the scan manually.
