Which of the following file types allows a user to easily uninstall software from macOS by simply placing it in the trash bin?
Correct Answer:
C
app files are application bundles that contain all the necessary files and resources for a Mac app. They can be easily deleted by dragging them to the Trash or using Launchpad12. Other file types, such as .exe, .dmg, .rpm, and .pkg, are either not compatible with macOS or require additional steps to uninstall34.

A network technician is deploying a new machine in a small branch office that does not have a DHCP server. The new machine automatically receives the IP address of 169.254.0.2 and is unable to communicate with the rest of the network. Which of the following would restore communication?
Correct Answer:
A
A static entry is the best option to restore communication for the new machine in a small branch office that does not have a DHCP server. A static entry means manually configuring the IP address, subnet mask, default gateway, and DNS server for the network adapter of the machine. A static entry ensures that the machine has a valid and unique IP address that matches the network configuration and can communicate with the rest of the network.
The new machine automatically receives the IP address of 169.254.0.2 because it uses APIPA (Automatic Private IP Addressing), which is a feature that enables computers to self-assign an IP address when a DHCP server is not available. However, APIPA only works for local communication within the same subnet, and does not provide a default gateway or a DNS server. Therefore, the new machine is unable to communicate with the rest of the network, which may be on a different subnet or require a gateway or a DNS server to access.
The other options are not related to restoring communication for the new machine. ARP table is a cache that stores the mapping between IP addresses and MAC addresses for the devices on the network. NTP specification is a protocol that synchronizes the clocks of the devices on the network.

Which of the following wireless security features can be enabled lo allow a user to use login credentials to attach lo available corporate SSIDs?
Correct Answer:
D
WPA2/AES (Wi-Fi Protected Access 2/Advanced Encryption Standard) is a wireless security standard that supports enterprise mode, which allows a user to use login credentials (username and password) to authenticate to available corporate SSIDs (service set identifiers). TACACS+ (Terminal Access Controller Access-Control System Plus) and Kerberos are network authentication protocols, but they are not wireless security features. Preshared key is another wireless security feature, but it does not use login credentials.

A user is unable to log in to the network. The network uses 802.1X with EAP-TLS to authenticate on the wired network. The user has been on an extended leave and has not logged in to the computer in several months. Which of the following is causing the login issue?
Correct Answer:
A
EAP-TLS is a method of authentication that uses certificates to establish a secure tunnel between the client and the server3. The certificates have a validity period and must be renewed before they expire1. If the user has been on an extended leave and has not logged in to the computer in several months, it is possible that the certificate on the client or the server has expired and needs to be renewed2. The other options are not directly related to EAP-TLS authentication or 802.1X network access.
Users access files in the department share. When a user creates a new subfolder, only that user can access the folder and Its files. Which of the following will MOST likely allow all users to access the new folders?
Correct Answer:
B
Enabling inheritance is a method that allows new subfolders to inherit the permissions and settings from their parent folder. If users can access files in the department share, but not in the new subfolders created by other users, it may indicate that inheritance is disabled and that each new subfolder has its own permissions and settings that restrict access to only the creator. Enabling inheritance can help resolve this issue by allowing all users to access the new subfolders with the same permissions and settings as the department share. Assigning share permissions, requiring multifactor authentication, and removing archive attribute are not methods that can most likely allow all users to access the new folders.
