Which of the following file systems will the technician MOST likely use? A. FAT32 B. ext4 C. NTFS D. exFAT Answer: D Explanation: exFAT is the most "universally" compatible option of the 4. exFAT covers all the bases. It supports single file sizes in a size range larger than the largest available consumer disk drives, let alone removeable media. In addition, it's generally compatible with Linux, due to being a simple system overall. FAT32 only supports file sizes up to 4 GB, which may or may not be acceptable for this transfer, as we don't know if it's a single 20 GB file or multiple 4GB or less files. Because it isn't stated, don't assume multiple files, go only with what is supplied. 20GB, so CompTIA probably wants to see that you know FAT32 doesn't work with files greater than 4GB. ext4 would work with Linux, but I'll be honest, in over 5 years working in IT, I have never formatted a drive ext4 for desktop level use. NTFS was developed as a primarily "Windows" file format, and while some version of Linux may work with it, there is the chance for compatibility issues.

The user will need to access advanced features and configuration settings for several applications. Which of the following BEST describes the account access level the user will need? A. Power user account B. Standard account C. Guest account D. Administrator account Answer: A Here's why a Power user account is appropriate in this scenario: Advanced Features: Power user accounts are designed to give users more control than a standard user account but less than an administrator account. They can perform tasks such as installing and configuring applications and accessing advanced features without having full administrative privileges. Least Privilege: While Power user accounts don’t have as much control as Administrator accounts, they still provide the necessary access to configure and manage applications effectively. This aligns with the principle of least privilege by providing just enough access for the user to perform their job functions. Other options and their considerations: B. Standard account: This account type has limited permissions and may not allow the user to access or configure advanced features of applications. C. Guest account: This account type is extremely limited and is intended for temporary use or minimal access. It is not suitable for users who need to perform advanced tasks or configurations. D. Administrator account: While an Administrator account provides full control over the system, it is generally more access than necessary and does not adhere to the principle of least privilege. It should be used only when absolutely required. Placing Windows user accounts in the Power Users security group is a common approach IT organizations take to get users into a least-privilege environment while avoiding the many pains of truly running as a limited user. The Power Users group is able to install software, manage power and time-zone settings, and install ActiveX controls, actions that limited Users are denied.

However, specific IP addresses are working. Which of the following does the technician MOST likely need to change on the workstation to resolve the issue? A. Default gateway B. Host address C. Name server D. Subnet mask Answer: C Explanation: When a user enters a website name or URL into a web browser, the computer sends a request to a DNS server to resolve the domain name into an IP address that the computer can use to connect to the server hosting the website. This process is called DNS resolution. If a user can access specific IP addresses but cannot resolve external web pages, it could indicate a problem with the DNS server settings on the user's workstation. The DNS server settings on the workstation could be incorrect or pointing to an invalid DNS server. In this scenario, the technician would need to change the name server settings on the workstation to point to a valid DNS server that can correctly resolve domain names into IP addresses. The default gateway, host address, and subnet mask settings are not typically related to DNS resolution and would not resolve the issue of not being able to resolve external web pages.
