A network administrator notifies a technician that the company is experiencing a DDoS attack. Several internal Windows PCs are the source of the traffic. The network administrator gives the technician the Windows computer names and states they be scanned and cleaned immediately. With which of the following types of infections are the PCs MOST likely infected? (Select two.)
-
Spyware
-
Zombies
-
Virus
-
Ransomware
-
Worm

Correct Answer(s)
A. Zombies
A. WormExplanation
The PCs are most likely infected with Zombies and Worms. Zombies are computers that have been infected with malware and are controlled remotely by a hacker to carry out malicious activities, such as participating in a DDoS attack. Worms are self-replicating malware that spread across a network and can cause significant damage by consuming network bandwidth and resources. In this scenario, the fact that multiple internal Windows PCs are the source of the DDoS attack suggests that they have been infected with malware that allows them to be controlled as zombies and spread as worms.Rate this question:

A wireless access point is going to be configured in a small office located in a crowded building. Which of the following should the installation technician perform to increase the security of the wireless network? (Select two.)
-
Reduce the transmit power
-
Reduce the channel availably
-
Enable QoS management
-
Disable the SSID broadcast
-
Implement WPA encryption
Correct Answer(s)
A. Reduce the transmit power
A. Disable the SSID broadcastExplanation
To increase the security of the wireless network in a crowded building, the installation technician should reduce the transmit power of the wireless access point. By reducing the transmit power, the signal range will be limited to the office area, making it more difficult for unauthorized users outside the office to access the network. Additionally, the technician should disable the SSID broadcast. This will prevent the wireless network from being visible to nearby devices, making it harder for potential attackers to identify and target the network.Rate this question:

A SOHO technician recently moved some data from one server to another to increase storage capacity. Several users are now reporting they cannot access certain shares on the network. When the users attempt to access the shares, they get the following error: Access Denied. The technician confirms the users are all in the proper security groups and have the proper access, but they are still unable to access the shares. Which of the following are the MOST likely reasons for these issues? (Select two.)
-
Administrative share permissions
-
Mapped drives
-
Group Policy hours restriction
-
Denied write/delete permissions
-
Disabled proxy settings
Correct Answer(s)
A. Mapped drives
A. Denied write/delete permissionsExplanation
The users' inability to access certain shares on the network could be due to two main reasons. Firstly, the issue could be related to mapped drives. If the technician moved the data from one server to another, the mapped drives may still be pointing to the old server, resulting in access denial. Secondly, the problem could be caused by denied write/delete permissions. Even if the users are in the proper security groups and have the proper access, they may not have the necessary permissions to write to or delete files in the shares, leading to the access denied error.Rate this question:

A small business has an open WiFi network for employees but does not want customers to connect to the access point. A technician has been dispatched to address the business’s concerns. Which of the following configuration settings should the technician change to satisfy the requirements of the business? (Select two.)
-
Default SSID
-
MAC filtering
-
NAT
-
QoS
-
Signal strength
-
Encryption
Correct Answer(s)
A. MAC filtering
A. Signal strengthExplanation
The technician should change the configuration settings of MAC filtering and signal strength to satisfy the requirements of the business. MAC filtering allows the business to create a list of approved MAC addresses, ensuring that only authorized devices can connect to the network. By enabling MAC filtering, the technician can prevent customers from connecting to the access point. Adjusting the signal strength can help limit the range of the WiFi network, ensuring that it is only accessible to employees within the business premises and not to customers outside the premises.Rate this question:
