SK0-005 Exam Dumps - CompTIA Server+ Certification Exam

The error message "Configuring Memory..." and the fact that the server is stuck at this point strongly suggest that a DIMM (memory module) has failed. Memory issues are commonly diagnosed when servers hang during the memory configuration phase of boot.

DIMM failure (Answer A): When a memory module fails, the server can get stuck at the memory initialization process during boot.

VRAM insufficiency (Option B): VRAM (video memory) issues would typically cause display-related errors, not memory configuration issues.

RAID cache failure (Option C): RAID cache issues would lead to storage errors but not prevent the system from configuring memory.

BIOS update (Option D): While BIOS issues can cause boot failures, the error message suggests a memory-specific issue.

Overprovisioning refers to allocating more resources (e.g., CPU, memory) to virtual machines on a hypervisor than the physical host actually has available. This is done because not all virtual machines are likely to use their maximum resources simultaneously. Overprovisioning helps optimize resource utilization on a hypervisor but must be managed carefully to avoid performance degradation.

Overprovisioning (Answer B): It allows for more efficient use of resources, but overcommitting too much can lead to performance issues.

Direct access (Option A): Refers to direct hardware access, which is unrelated to resource allocation.

Link aggregation (Option C): Refers to combining multiple network connections, unrelated to hypervisor resources.

Component redundancy (Option D): Refers to using backup components for fault tolerance, not related to overprovisioning.

Scalability (Option E): Refers to the ability to increase or decrease resources as needed but doesn't describe overcommitting resources.

CompTIA Server+ Reference:This topic is covered under SK0-005 Objective 1.3: Explain virtualization concepts and benefits.

A Type 1 hypervisor (also known as a bare-metal hypervisor) is installed directly on the hardware and is designed to manage multiple virtual machines. It is the most common type of hypervisor used in virtualization environments.

Type 1 hypervisor (Answer A): This is a core technology that enables virtualization by running virtual machines directly on the physical hardware.

Bare-metal installation (Option B): Refers to installing an OS or hypervisor directly on hardware, but doesn't inherently support virtualization unless it's a hypervisor.

Server-level redundancy (Option C): This provides fault tolerance but is not related to virtualization.

Active-active load balancing (Option D): Refers to distributing workloads across multiple servers, not directly tied to virtualization.

The backup type that only records changes to the data blocks on a virtual machine is snapshot. A snapshot is a point-in-time copy of a virtual machine (VM) that captures the state and data of the VM at a specific moment. A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the VM after the snapshot was taken. A snapshot can be used to restore the VM to its previous state in case of data loss or corruption.

Recovery Time Objective (RTO) refers to the target time set for the recovery of IT and business activities after a disaster has struck, which includes restoring server, network, and data access. The policy requirement mentioned in the question aligns with the definition of RTO, as it specifies the maximum allowable downtime or the time within which functionality must be restored. Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR) are metrics related to the reliability and repair times of systems but do not specifically pertain to disaster recovery time frames. Recovery Point Objective (RPO) describes the acceptable amount of data loss measured in time, not the restoration of operations.

QSFP+ (Quad Small Form-factor Pluggable Plus) connectors are used in high-density, high-speed networking solutions such as 40 Gigabit Ethernet (40GbE) interfaces. When upgrading a server's network to 40Gbps, QSFP+ is the appropriate choice due to its capability to support such high-speed data transfer rates. 10 GigE, SFP, and SFP+ connectors are used for lower speed connections (10Gbps and below for SFP+ and 10 GigE, and even less for SFP), making them unsuitable for a 40Gbps network upgrade.

A database server is a server that hosts a database management system (DBMS) that stores, organizes, and manipulates data. A database server is suitable for housing customer sales records, as it can provide fast and secure access, query and analysis capabilities, backup and recovery options, and scalability and performance optimization. Some examples of database servers are Microsoft SQL Server, Oracle Database, MySQL, and PostgreSQL. Verified References: [What is a Database Server?]

RAID 5 configuration: Using five of the available drives in a RAID 5 configuration meets the requirements for:

Storage capacity: Four 600GB drives (2, 5, and 6) provide a total usable capacity of 2.4TB (4 * 600 * 0.8), exceeding the minimum requirement of 2TB. RAID 5 introduces parity data for fault tolerance, sacrificing some usable space (one drive's worth).

Performance: The combination of multiple drives in a RAID 5 array improves read performance compared to a single drive setup.

Fault tolerance: Even with a single drive failure (any of the five drives used in the RAID 5), the remaining drives can reconstruct the lost data, allowing the server to continue operating.
