Free Access CompTIA SK0-005 New Release

The access control methodology that can be described best as allowing a user the least access based on the jobs the user needs to perform is role-based access control (RBAC). RBAC is an access control method that assigns permissions to users based on their roles or functions within an organization. RBAC provides fine-grained and manageable access control by defining what actions each role can perform and what resources each role can access. RBAC follows the principle of least privilege, which means that users are only granted the minimum level of access required to perform their tasks. RBAC can reduce security risks, simplify administration, and enforce compliance policies.

The most likely reasons why the technician is unable to access a server’s package repository internally or externally are that the external firewall is blocking access and that the default gateway is incorrect. A package repository is a source of software packages that can be installed or updated on a server using a package manager tool. A package repository can be accessed over a network using a URL or an IP address. However, if there are any network issues or misconfigurations, the access to the package repository can be blocked or failed. An external firewall is a device or software that controls the incoming and outgoing network traffic based on predefined rules or policies. An external firewall can block access to a package repository if it does not allow traffic on certain ports or protocols that are used by the package manager tool. A default gateway is a device or address that routes network traffic from one network to another network. A default gateway can be incorrect if it does not match the actual device or address that connects the server’s network to other networks, such as the internet. An incorrect default gateway can prevent the server from reaching the package repository over other networks. QUESTION NO: 63 Correct Answer: A Explanation: The RAID level that provides the highest possible capacity for a storage array is RAID 0. RAID 0 is a type of RAID level that provides performance enhancement by using striping. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. RAID 0 does not provide any fault tolerance or redundancy, as it does not use any parity or mirroring techniques. RAID 0 uses all of the available disk space for data storage, without losing any space for overhead. Therefore, RAID 0 provides the highest possible capacity for a storage array, but also has the highest risk of data loss.

• HTTPS (Secure Web Traffic): Port 443 is the standard port for HTTPS, which is essential for encrypting communication between web browsers and a secure website. (CompTIA Server+ Objectives SK0-004: 4.1)
• Why other options are not essential:

Faulty memory and incorrectly seated memory are likely causes of the random BSOD conditions on the server. Memory is one of the most common hardware components that can cause BSOD (Blue Screen of Death) errors on Windows systems. BSOD errors occur when the system encounters a fatal error that prevents it from continuing to operate normally. Memory errors can be caused by faulty or incompatible memory modules that have physical defects or manufacturing flaws. Memory errors can also be caused by incorrectly seated memory modules that are not properly inserted or locked into the memory slots on the motherboard. This can result in loose or poor connections between the memory modules and the motherboard.
