A server administrator just installed a new physical server and needs to harden the OS. Which of the following best describes the OS hardening method?
Applying security updates is one of the common operating system hardening methods that can help protect the OS from cyberattacks and vulnerabilities. Security updates are released by the OS developer to fix bugs, patch security holes, and improve performance.By installing the latest updates, the server administrator can ensure that the OS is up to date and secure12.
A technician receives reports that a file server is performing slower than usual after a power failure. While investigating the issue, the technician discovers the write cache was disabled. The technician checks a server configuration document and confirms the cache was previously enabled. Which of the following events most likely caused this change?
Comprehensive and Detailed
Write caching improves disk performance by temporarily storing write operations in faster cache memory before writing to disk. However, to prevent data loss during power failures, write caching relies on a battery-backed cache. If the RAID controller's battery fails, the system may automatically disable write caching to protect data integrity, leading to reduced performance.
Which of the following will protect critical data during a natural disaster?
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.
A technician needs to provide a VM with high availability. Which of the following actions should the technician take to complete this task as efficiently as possible?
Cloning the original VM is the most efficient way to provide a VM with high availability. Cloning is the process of creating an exact copy of a VM, including itsconfiguration, operating system, applications, and data. A cloned VM can be used as a backup or a replica of the original VM, and can be powered on and run independently. Cloning can be done quickly and easily using vSphere tools or other third-party software. By cloning the original VM and placing it on a different host server or availability zone, the technician can ensure that if the original VM fails, the cloned VM can take over its role and provide uninterrupted service to the users and applications.
An administrator has been asked to increase the storage capacity of a stand-alone file server but no further expansion slots are available. Whichof the following would be the FASTEST solution to implement with no downtime?
A SAN (Storage Area Network) is a network of storage devices that can provide shared storage capacity to multiple servers. By connecting the server to a SAN, theadministrator can increase the storage capacity of the server without adding any internal disks or expansion cards. This solution can be implemented quickly and without any downtime. Verified Reference: [What is a SAN and how does it differ from NAS?]
