Free Practice Questions for CompTIA SK0-005 Exam

Government regulationsoften dictate the legal requirements for data storage, privacy, and security, which can greatly impact the selection of a cloud provider. Compliance with regulations like GDPR, HIPAA, or other local laws is critical when choosing a cloud provider to avoid legal repercussions.

Government regulations (Answer B):Cloud providers must comply with legal and regulatory requirements, making this a significant factor in provider selection.

Industry standards (Option A):While important, standards can be more flexible and are often not legally binding.

Company policy (Option C):Internal policies are important but usually stem from the need to comply with regulations.

Organizational procedures (Option D):Procedures help guide operations but don’t typically dictate the choice of cloud providers.

CompTIA Server+ Reference:This topic is covered underSK0-005 Objective 1.6: Explain the importance of cloud-based concepts and services.

Different storage protocols operate at different levels (file-based vs. block-based):

iSCSI (Internet Small Computer Systems Interface) is a block-level protocol, meaning that the storage appears as raw disk space to the operating system. Backups would require copying entire blocks, rather than specific files.

FC (Fibre Channel) is another block-level protocol used in high-performance SANs. It does not support file-based storage natively.

FCoE (Fibre Channel over Ethernet) extends FC over Ethernet but still functions as a block-based storage solution.

NFS (Network File System) is a file-based storage protocol, making it the best option. It allows direct access to files, which enables backup software to back up only modified files instead of the entire block device.

Since the administrator requires a file-based storage protocol to ensure efficient incremental backups, NFS is the correct choice.

When a server crashes with a Blue Screen of Death (BSOD) and is not responding, the most effective way to reboot it remotely must be chosen:

Crash cart (A): A crash cart is a physical device used for troubleshooting at the server location. Since the administrator wants a remote reboot, this is not suitable.

KVM (B): A KVM (Keyboard, Video, Mouse) switch allows remote management of multiple servers but does not inherently provide reboot capabilities.

IRMI (C) - Intelligent Remote Management Interface: This is the best option. Many enterprise servers have Intelligent Platform Management Interface (IPMI) or Integrated Lights-Out (iLO) management tools that allow remote power control, including forced reboots.

shutdown -r (D): This command is used to restart a server via an operating system command-line interface. However, since the server is not responding, this command cannot be executed.

Since the server is unresponsive, the best method is to use the remote management interface (IRMI/IPMI/iLO) to force a reboot.

Off-site storage involves storing data backups in a physically separate location from where the servers and primary data reside. This protects critical data in case the main site is damaged or destroyed due to a natural disaster, such as floods, fires, or earthquakes. Off-site storage can be in the form of cloud storage or physical tapes stored in a geographically distant location.

Off-site storage (Answer A):It ensures that a company's critical data remains accessible even if the local infrastructure is compromised. This is a common part of disaster recovery planning and is crucial for business continuity.

Life-cycle management (Option B):While important for managing data from creation to deletion, it does not specifically protect data during disasters.

Environmental controls (Option C):These manage physical conditions like temperature and humidity but do not address the risk of data loss during disasters.

Data-at-rest encryption (Option D):Encryption protects the confidentiality of stored data but does not ensure availability in the event of a disaster.

CompTIA Server+ Reference:This topic is covered underSK0-005 Objective 4.1: Summarize disaster recovery methods and concepts.

When a virtual server crashes and presents a Purple Screen of Death (PSOD), the immediate response should be to document the incident. Collecting a screenshot of the PSOD is crucial as it contains error codes and state information that can be used for diagnosing the root cause of the crash. Noting the details, especially those that come after the line detailing the OS version, can provide specific clues to what might have caused the server to crash. This is a standard best practice before rebooting the server, as it ensures that there is a record of the event to investigate and potentially prevent future occurrences. A hard reboot should only be done after this critical information has been recorded.

Drive encryption is a form of data-at-rest encryption that encrypts the entire hard drive or solid state drive. This means that all the data on the drive, including the operating system, applications, and files, are protected from unauthorized access. Drive encryption is usually implemented at the hardware or firmware level, and requires a password, PIN, or biometric authentication to unlock the drive. Drive encryption is the most comprehensive and secure way to achieve data-at-rest encryption, as it prevents anyone from accessing the data without the proper credentials, even if they physically remove the drive from the server.

 Application consistent backup is a method of backing up data that ensures the integrity and consistency of the application state. It involves notifying the application to flush its data from memory to disk and quiescing any write operations before taking a snapshot of the data. If the databases were not backed up to be application consistent, they might contain incomplete or corrupted data that cannot be restored properly.

Asecurity guardis a human element in physical security, making them susceptible tosocial engineering attacks. Social engineering exploits human behavior, and a guard can be tricked into allowing unauthorized access through persuasion, manipulation, or deception.

Security guard (Answer A):Human elements are the most vulnerable to social engineering techniques like impersonation or manipulation.

Access control vestibule (Option B):This is a physical security barrier, which is harder to exploit through social engineering.

Perimeter fencing (Option C):This is a static physical barrier, not susceptible to social engineering.

Biometric locks (Option D):These rely on biological data and are not susceptible to social engineering in the same way a human would be.

Bollards (Option E):Physical barriers that are not vulnerable to social engineering.

CompTIA Server+ Reference:This topic relates toSK0-005 Objective 4.4: Implement physical security controls.

The upgrade involves transitioning from 10Gb copper to 25Gb fiber, which requires appropriate network interface hardware:

FCoE (A) - Fibre Channel over Ethernet: This protocol allows Fibre Channel to run over Ethernet networks, but it does not address the physical change from copper to fiber.

VLAN ID (B): VLANs segment networks but do not impact the physical connectivity (copper vs. fiber).

SFP (C) - Small Form-factor Pluggable: SFP transceivers are hot-swappable modules used in network interfaces to support fiber connections. A 25Gb SFP28 transceiver would be required for the transition from 10Gb copper to 25Gb fiber. This is the correct answer.

HBA (D) - Host Bus Adapter: HBAs are typically used for storage connectivity (such as Fibre Channel SANs), not general network upgrades.

Since SFP modules allow servers to support fiber connections, this is the best choice for upgrading from 10Gb copper to 25Gb fiber.
