CompTIA Updated 220-1102 Exam Questions and Answers by tyson

When upgraded computers are not able to obtain an IP address, the issue often lies in the network configuration. Here’s a

Option A: The switch is only providing IPv6 addresses.This is unlikely because if the switch were providing IPv6 addresses, the devices would still receive an IP address, albeit an IPv6 one. The issue described indicates no IP address is being obtained at all.

Option B: The OS must be updated to be compatible with the imaging software.This option is unrelated to obtaining an IP address. Compatibility with imaging software would not prevent the devices from getting an IP address.

Option C: The switch has port security enabled.Correct Answer. Port security on a switch restricts access based on MAC addresses. If the MAC addresses of the upgraded computers are not recognized or have not been added to the allowed list, the switch will not provide network access, resulting in the computers not obtaining an IP address.

The best protection against physical threats, especially in a common area where the computer is publicly accessible, involves physically securing the hardware.

Option A: Using screen lockScreen locks are good for securing access temporarily but do not protect against physical tampering or theft.

Option B: Installing a privacy screenPrivacy screens prevent visual access but do not secure the hardware.

Option C: Implementing password complexityPassword complexity helps secure digital access but does not prevent physical threats.

Option D: Locking the computer casePhysically securing the case prevents unauthorized individuals from tampering with internal components or stealing the computer.

Option E: Enabling drive encryptionEncryption protects data but does not prevent physical access to the hardware itself.

When a user is unable to access shared drives from a company-issued laptop while working from home, the likely requirement is:

VPN (Virtual Private Network): A VPN allows secure access to the company’s network from a remote location. Without a VPN connection, the user cannot access network resources such as shared drives.

IPv6: Involves IP addressing and is not directly related to accessing shared drives.

IPS (Intrusion Prevention System): Provides network security but does not facilitate access to shared drives.

DNS: Manages domain name resolution and is not typically the issue when specific shared drives are inaccessible.

To manually add a workstation to a domain, the technician needs to access the System Properties menu where domain settings are configured.

User Accounts: Manages user accounts but does not handle domain membership.

System Properties: The correct place to add or change domain membership settings.

Windows Firewall: Manages firewall settings but not domain membership.

Network and Sharing: Manages network connections and sharing but not domain settings.
