CompTIA A+ Certification Exam: Core 2 Sample Questions (Q653-Q658):
NEW QUESTION # 653
A branch office suspects a machine contains ransomware. Which of the following mitigation steps should a technician take first?
Answer: C
Explanation:
The first mitigation step that a technician should take when a machine is suspected to contain ransomware is to quarantine the system. This means isolating the infected machine from the network and other devices, to prevent the ransomware from spreading and encrypting more data. The technician can quarantine the system by disconnecting the network cable, turning off the wireless adapter, or using firewall rules to block the traffic from and to the machine12.
This step is more important than the other options because:
* Disabling System Restore (A) is not a priority, as it will not stop the ransomware from running or spreading. System Restore is a feature that allows users to restore their system to a previous state, but it may not work if the ransomware has encrypted or deleted the restore points. Moreover, disabling System Restore may prevent the user from recovering some data or settings in the future13.
* Remediating the system (B) is the ultimate goal, but it cannot be done before quarantining the system.
Remediating the system means removing the ransomware, restoring the data, and fixing the vulnerabilities that allowed the attack. However, this process requires careful analysis, planning, and execution, and it may not be possible if the ransomware is still active and communicating with the attackers. Therefore, the technician should first isolate the system and then proceed with the remediation steps12.
* Educating the system user is a preventive measure, but it is not a mitigation step. Educating the system user means raising awareness and providing training on how to avoid ransomware attacks, such as by recognizing phishing emails, avoiding suspicious links or attachments, and updating and patching the system regularly. However, this step will not help if the system is already infected, and it may not be
* effective if the user is not willing or able to follow the best practices. Therefore, the technician should focus on resolving the current incident and then educate the user as part of the recovery plan14.

NEW QUESTION # 654
Which of the following features allows a user to install software from a DVD even when the laptop running macOS does not have an optical drive?
Answer: C
NEW QUESTION # 655
A user takes a work-issued laptop home for the first time. When the user attempts to browse any website on the home internet, the user receives the following error:
"This site cannot be reached."
A technician from work confirms that the static IP that was set up on the machine was changed back to DHCP.
Which of the following needs to be corrected?
Answer: B
Explanation:
The error "This site cannot be reached" often indicates a problem with DNS (Domain Name System) resolution, where the browser is unable to translate a website's domain name into its corresponding IP address.
Since the laptop was set to use DHCP (Dynamic Host Configuration Protocol) at home, it's possible that it's not receiving the correctDNS server information from the home network, or the DNS servers it was using at work are not accessible from the home network.
DNS:Checking and possibly correcting the DNS settings to ensure they are appropriate for the home network might resolve the browsing issue. The user can try using public DNS servers like those provided by Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1) if the default DNS servers provided by the home ISP are not working properly.
HTTPS (A) is a protocol for secure communication over a computer network but is not something that needs to be configured on the user's end to solve this type of issue. VLAN (B) stands for Virtual Local Area Network and is more related to network segmentation and management within larger networks, not typically applicable to home internet issues. SMTP (D) stands for Simple Mail Transfer Protocol, which is used for sending emails, not for general web browsing issues.

NEW QUESTION # 657
A technician needs to establish a remote access session with a user who has a Windows workstation. The session must allow for simultaneous viewing of the workstation by both the user and technician. Which of the following remote access technologies should be used?
Answer: C
Explanation:
MSRA (Microsoft Remote Assistance) is a remote access technology that allows a technician to establish a session with a user who has a Windows workstation. The session allows for simultaneous viewing of the workstation by both the user and technician, as well as remote control and file transfer capabilities. RDP (remote desktop protocol) is another remote access technology, but it does not allow simultaneous viewing by default. VPN (virtual private network) and SSH (secure shell) are protocols that create secure tunnels between two devices over the internet, but they do not allow remote access sessions.
