NEW QUESTION # 256
A company-owned mobile device is displaying a high number of ads, receiving data-usage limit notifications, and experiencing slow response. After checking the device, a technician notices the device has been jailbroken. Which of the following should the technician do next?
- A. Restore the defaults and reimage the corporate OS.
- B. Undo the jailbreak and enable an antivirus.
- C. Back up the files and do a system restore.
- D. Run an antivirus and enable encryption.
Answer: A
Explanation:
The best course of action for the technician is to restore the defaults and reimage the corporate OS on the device. This will remove the jailbreak and any unauthorized or malicious apps that may have been installed on the device, as well as restore the security features and policies that the company has set for its devices. This will also ensure that the device can receive the latest updates and patches from the manufacturer and the company, and prevent any data leakage or compromise from the device.
Jailbreaking is a process of bypassing the built-in security features of a device to install software other than what the manufacturer has made available for that device1. Jailbreaking allows the device owner to gain full access to the root of the operating system and access all the features1. However, jailbreaking also exposes the device to various risks, such as:
* The loss of warranty from the device manufacturers2.
* Inability to update software until a jailbroken version becomes available2.
* Increased security vulnerabilities32.
* Decreased battery life2.
* Increased volatility of the device2.
Some of the signs of a jailbroken device are:
* A high number of ads, which may indicate the presence of adware or spyware on the device3.
* Receiving data-usage limit notifications, which may indicate the device is sending or receiving data in the background without the user's knowledge or consent3.
* Experiencing slow response, which may indicate the device is running unauthorized or malicious apps that consume resources or interfere with the normal functioning of the device3.
* Finding apps or icons that the user did not install or recognize, such as Cydia, which is a storefront for jailbroken iOS devices1.
The other options are not sufficient or appropriate for dealing with a jailbroken device. Running an antivirus and enabling encryption may not detect or remove all the threats or vulnerabilities that the jailbreak has introduced, and may not restore the device to its original state or functionality. Backing up the files and doing a system restore may not erase the jailbreak or the unauthorized apps, and may also backup the infected or compromised files. Undoing the jailbreak and enabling an antivirus may not be possible or effective, as the jailbreak may prevent the device from updating or installing security software, and may also leave traces of the jailbreak or the unauthorized apps on the device.

NEW QUESTION # 257
The calendar application on an employee's smartphone is experiencing frequent crashes, and the smartphone has become unresponsive. Which of the following should a technician do first to resolve the issue?
- A. Reinstall the application on the smartphone.
- B. Reset the smartphone to factory settings.
- C. Reboot the smartphone.
- D. Update the smartphone's OS.
Answer: C
Explanation:
Explanation
Rebooting the smartphone is the first and simplest step to resolve the issue of frequent crashes and unresponsiveness. Rebooting clears the memory, closes the background apps, and refreshes the system. It can also fix minor glitches and bugs that may cause the calendar app or the smartphone to malfunction12. The other options are either too drastic or unnecessary. Reinstalling the application may not solve the problem if the issue is with the smartphone itself. Updating the smartphone's OS may not be possible or helpful if the device is unresponsive or incompatible. Resetting the smartphone to factory settings will erase all the data and settings on the device, which should be the last resort.

NEW QUESTION # 258
A user's work PC has been the target of multiple phishing attacks. Which of the following is a way for the user to prevent further attacks?
- A. Activating the email spam filter
- B. Running vulnerability scans on a schedule
- C. Using a secure VPN connection
- D. Enabling Windows Firewall
Answer: A
Explanation:
Phishing attacks are typically delivered via email, so the most effective immediate measure is to filter out these malicious emails.

NEW QUESTION # 260
A technician is trying to connect to a user's laptop in order to securely install updates. Given the following information about the laptop:
Which of the following should the technician do to connect via RDP?
- A. Change the subnet mask on the user's laptop.
- B. Confirm the user can ping the default gateway.
- C. Change the IP address on the user's laptop.
- D. Open port 3389 on the Windows firewall.
Answer: D
Explanation:
In order to connect to a user's laptop via RDP, the technician should open port 3389 on the Windows firewall. This is because RDP uses port 3389 for communication12. The other options are not necessary or relevant for establishing an RDP connection.
Confirming the user can ping the default gateway is not required for RDP, as it only tests the network connectivity between the user's laptop and the router. RDP works over the internet, so the technician should be able to ping the user's laptop directly using its IP address3.
Changing the IP address on the user's laptop is not needed for RDP, as long as the IP address is valid and not conflicting with another device on the network. The user's laptop has a valid IP address of 192.168.0.45, which belongs to the same subnet as the gateway (192.168.0.1) and the subnet mask (255.255.255.0)4.
Changing the subnet mask on the user's laptop is not required for RDP, as long as the subnet mask matches the network configuration. The user's laptop has a correct subnet mask of 255.255.255.0, which defines a network with 254 possible hosts4.

- A. Adjust the content filtering.
- B. Disable unused ports.
- C. Unmap port forwarding.
- D. Reduce the encryption strength
Answer: A
Explanation:
Content filtering is a process that manages or screens access to specific emails or webpages based on their content categories1. Content filtering can be used by organizations to control content access through their firewalls and enforce corporate policies around information system management2. A SOHO client may have content filtering enabled on their network and may need to adjust it to allow access to a corporate website that is blocked by default. The client can use a software program, a hardware device, or a subscription service to configure the content filtering settings and whitelist the desired website2.

NEW QUESTION # 263
A technician successfully removed malicious software from an infected computer after running updates and scheduled scans to mitigate future risks. Which of the following should the technician do next?
- A. Educate the end user on best practices for security.
- B. Investigate how the system was infected with malware.
- C. Quarantine the host in the antivirus system.
- D. Create a system restore point.
Answer: A
Explanation:
Educating the end user on best practices for security is the next step that the technician should take after successfully removing malicious software from an infected computer. Educating the end user on best practices for security is an important part of preventing future infections and mitigating risks. The technician should explain to the end user how to avoid common sources of malware, such as phishing emails, malicious websites, or removable media. The technician should also advise the end user to use strong passwords, update software regularly, enable antivirus and firewall protection, and backup data frequently. Educating the end user on best practices for security can help the end user become more aware and responsible for their own security and reduce the likelihood of recurrence of malware infections. Quarantining the host in the antivirus system, investigating how the system was infected with malware, and creating a system restore point are not the next steps that the technician should take after successfully removing malicious software from an infected computer. Quarantining the host in the antivirus system is a step that the technician should take before removing malicious software from an infected computer. Quarantining the host in the antivirus system means isolating the infected computer from the network or other devices to prevent the spread of malware.
Investigating how the system was infected with malware is a step that the technician should take during or after removing malicious software from an infected computer. Investigating how the system was infected with malware means identifying the source, type, and impact of malware on the system and documenting the findings and actions taken. Creating a system restore point is a step that the technician should take before removing malicious software from an infected computer. Creating a system restore point means saving a snapshot of the system's configuration and settings at a certain point in time, which can be used to restore the system in case of failure or corruption.

NEW QUESTION # 264
A technician is troubleshooting a PC that is unable to perform DNS lookups. Utilizing the following firewall output:
Protocol/PortActionDirection
1AllowOut
445BlockOut
53BlockOut
123BlockOut
80BlockOut
Which of the following ports should be opened to allow for DNS recursion?
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
Answer: C
Explanation:
DNS (Domain Name System) lookups are essential for translating human-friendly domain names into IP addresses that computers use to communicate. DNS typically uses port 53 for its communication.
In the provided firewall output, various ports are either allowed or blocked for outgoing traffic. For DNS recursion, which is the process of resolving domain names to IP addresses, port 53 must be open.
Port 53:This is the standard port used by DNS for queries and responses. The fact that it is currently blocked (as per the firewall output) is the reason why DNS lookups are failing. Opening port 53 will allow the DNS requests to pass through the firewall, enabling the resolution of domain names to IP addresses.
Other ports mentioned in the output are used for different services and protocols:
Port 1 is generally not used for standard services.
Port 445 is associated with SMB (Server Message Block) for file sharing in Windows environments.
Port 123 is used by NTP (Network Time Protocol) for time synchronization.
Port 80 is used for HTTP traffic, which is web traffic but not related to DNS lookups.

- A. Degaussing the hard drive, flashing the BIOS, and then reinstalling the OS
- B. Reinstalling the OS. flashing the BIOS, and then scanning with on-premises antivirus
- C. Scanning the system with a Linux live disc, flashing the BIOS, and then returning the computer to service
- D. Flashing the BIOS, reformatting the drive, and then reinstalling the OS
Answer: D
Explanation:
Explanation
Flashing the BIOS, reformatting the drive, and then reinstalling the OS is the best method for returning a computer with a malware infection to service. Flashing the BIOS updates the firmware of the motherboard and can remove any malware that may have infected it. Reformatting the drive erases all data on it and can remove any malware that may have infected it. Reinstalling the OS restores the system files and settings to their original state and can remove any malware that may have modified them. Scanning the system with a Linux live disc may not detect or remove all malware infections. Degaussing the hard drive is an extreme method of destroying data that may damage the drive beyond repair. Reinstalling the OS before flashing the BIOS or scanning with antivirus may not remove malware infections that persist in the BIOS or other files.
