SK0-005 Exam Dumps - CompTIA Server+ Questions and Answers

The administrator should use an IP KVM to access the server’s console remotely for bare-metal maintenance. An IP KVM stands for Internet Protocol Keyboard Video Mouse, which is a device that allows remote control of a server’s keyboard, video, and mouse over a network connection, such as LAN or Internet. An IP KVM enables an administrator to perform tasks such as BIOS configuration, boot sequence selection, operating system installation, etc., without being physically present at the server location.

The other options are not suitable for bare-metal maintenance because they require either physical access to the server (a crash cart) or an operating system running on the server (VNC, RDP, SSH). A crash cart is a mobile unit that contains a monitor, keyboard, mouse, and cables that can be plugged into a server for direct access to its console. VNC stands for Virtual Network Computing, which is a software that allows remote desktop sharing and control over a network connection using a graphical user interface (GUI). RDP stands for Remote Desktop Protocol, which is a protocol that allows remote desktop access and control over a network connection using a GUI or command-line interface (CLI). SSH stands for Secure Shell, which is a protocol that allows secure remote login and command execution over a network connection using a CLI.

The best course of action to preserve business continuity for a very old PC that is running a critical, proprietary application in MS-DOS is to purchase matching hardware and clone the disk. This way, the technician can create an exact copy of the PC’s configuration and data on another PC that has the same specifications and compatibility. This will ensure that the application can run smoothly on the new PC without any installation or configuration issues. Performing scheduled chkdsk tests would not help, as chkdsk is a tool that checks and repairs disk errors, but does not prevent hardware failures or software compatibility issues. Upgrading the hard disk to SSD would not help either, as SSDs may not be compatible with the old PC or the MS-DOS operating system. Performing quarterly backups would help with data protection, but not with hardware availability or software compatibility.

The method that would help the administrator accomplish the task of creating new VMs in the shortest amount of time and meet the system requirements is template. A template is a preconfigured virtual machine image that contains an operating system, applications, settings, and other components. A template can be used to create multiple identical or customized VMs quickly and easily, without having to install and configure each VM from scratch. A template can save time and ensure consistency across VMs.

The best way to limit an attacker from exploiting a zero-day vulnerability that is impacting a service enabled on a server OS is to install the latest patches. Patches are updates that fix bugs, improve security, or add features to software. Installing patches can help prevent attackers from exploiting known vulnerabilities that have been fixed by the software vendor. A zero-day vulnerability is a vulnerability that is unknown to the vendor or the public until it is exploited by an attacker. Therefore, installing patches as soon as they are available can reduce the window of opportunity for attackers to exploit zero-day vulnerabilities.

The live failover testing method is the most likely one that the server administrator is performing when creating a downtime scenario and taking the necessary steps. A live failover test involves switching from the primary system to the secondary system (or backup site) in a real environment, without any simulation or preparation. A live failover test can evaluate the effectiveness and readiness of the disaster recovery plan, but it also carries a high risk of data loss, corruption, or disruption.

The next thing that the technician should do, given the disk is hot swappable, is to replace the disk. A hot swappable disk is a disk that can be removed and replaced without shutting down the system or affecting its operation. A hot swappable disk is typically used in a storage array that has RAID (Redundant Array of Independent Disks) configuration that provides fault tolerance and redundancy. If a disk fails in a RAID array, it can be replaced by a new disk without interrupting the service or losing any data. The new disk will automatically rebuild itself using the data from the other disks in the array.

QSFP+ is a type of connector that should be used to connect a server to a switch that uses 40G network connectivity. QSFP+ (Quad Small Form-factor Pluggable Plus) is a compact, hot-pluggable transceiver module that supports data rates up to 40 Gbps. QSFP+ modules can be used for various network protocols and media types, such as Ethernet, Fibre Channel, InfiniBand, or optical fiber. QSFP+ modules have a 38-pin edge connector and can be inserted into a QSFP+ port on a switch or a server. SFP+ (Small Form-factor Pluggable Plus) is a type of connector that supports data rates up to 10 Gbps, but not 40 Gbps. SFP+ modules have a 20-pin edge connector and can be inserted into an SFP+ port on a switch or a server. GBIC (Gigabit Interface Converter) is an older type of connector that supports data rates up to 1 Gbps, but not 40 Gbps. GBIC modules have an SC duplex connector and can be inserted into a GBIC port on a switch or a server. SFP (Small Form-factor Pluggable) is another older type of connector that supports data rates up to 1 Gbps or 4 Gbps, but not 40 Gbps. SFP modules have an LC duplex connector and can be inserted into an SFP port on a switch or a server.

The best strategy to ensure wayward vehicle traffic does not interfere with datacenter operations is to install bollards. Bollards are sturdy posts that are installed around a perimeter to prevent vehicles from entering or crashing into a protected area. Bollards can provide physical security and deterrence for datacenters that are located near busy roads or parking lots. Bollards can also prevent accidental damage or injury caused by vehicles that lose control or have faulty brakes.

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.

This is the most appropriate way to complete the task because it follows the best practices of cable management. Cable management is a process of organizing and securing cables in a rack or a server room to improve airflow, accessibility, safety, and aesthetics. Running the network cables up the left side and the power cables down the right side of the rack helps to avoid cable clutter, interference, and confusion. It also makes it easier to trace and troubleshoot cables if needed. Using appropriate-length cables also helps to reduce cable slack and excess. Wiring the cables through the cable management arm may cause stress and damage to the cables when moving the server in or out of the rack. Using the longest cables possible may create cable loops and tangles that can block airflow and increase fire hazards. Installing an Ethernet patch panel and a PDU (Power Distribution Unit) may be useful for accommodating more network and power cables, but not necessary for a single server.
