At ValidExamDumps, we consistently monitor updates to the CompTIA SK0-005 exam questions by CompTIA. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the CompTIA Server+ Certification Exam exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by CompTIA in their CompTIA SK0-005 exam. These outdated questions lead to customers failing their CompTIA Server+ Certification Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the CompTIA SK0-005 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
A server administrator set up a monitoring application on various servers to keep track of CPU usage, memory consumption, and disk space utilization. Which of the following should be configured on the application so it can send email alerts about a specific issue?
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:Configuringthresholdsallows the monitoring application to define limits (e.g., CPU usage >90%, disk space < 10%) that trigger email alerts when exceeded. This proactive measure helps administrators address issues before they escalate.
Event logs:Provide historical data but do not send alerts.
Disk quotas:Restrict user disk usage but are unrelated to alerts.
Uptime lengths:Measure server runtime but do not trigger alerts.
A server technician notices a server is very low on disk space. Upon inspecting the disk utilization, the technician discovers server logs are taxing up a large amount of space. There is no central log server. Which of the following would help free up disk space?
Log rotation is a process that periodically renames, compresses, and deletes old log files to free up disk space and keep log files manageable. Log rotation can be configured using tools such as logrotate or cron on Linux systems, or using Windows Task Scheduler or PowerShell scripts on Windows systems. Log rotation can also help with log analysis and troubleshooting by making it easier to find relevant information in smaller and more recent log files.

A server administrator is configuring the IP address on a newly provisioned server in the testing environment. The network VLANs are configured as follows:
The administrator configures the IP address for the new server as follows:
IP address: 192.168.1.1/24
Default gateway: 192.168.10.1
A ping sent to the default gateway is not successful. Which of the following IP address/default gateway combinations should the administrator have used for the new server?
The IP address/default gateway combination that the administrator should have used for the new server is IP address: 192.168.10.2/24 and Default gateway: 192.168.10.1. The IP address and the default gateway of a device must be in the same subnet to communicate with each other. A subnet is a logical division of a network that allows devices to share a common prefix of their IP addresses. Thesubnet mask determines how many bits of the IP address are used for the network prefix and how many bits are used for the host identifier. A /24 subnet mask means that the first 24 bits of the IP address are used for the network prefix and the last 8 bits are used for the host identifier. Therefore, any IP address that has the same first 24 bits as the default gateway belongs to the same subnet. In this case, the default gateway has an IP address of 192.168.10.1/24, which means that any IP address that starts with 192.168.10.x/24 belongs to the same subnet. The new server has an IP address of 192.168.1.1/24, which does not match the first 24 bits of the default gateway, so it belongs to a different subnet and cannot communicate with the default gateway. To fix this issue, the administrator should change the IP address of the new server to an unused IP address that starts with 192.168.10.x/24, such as 192.168.10.2/24.
Following a recent power outage, a server in the datacenter has been constantly going offline and losing its configuration. Users have been experiencing access issues while using the application on the server. The server technician notices the data and time are incorrect when the server is online. All other servers are working. Which of the following would MOST likely cause this issue? (Choose two.)
The server has a CMOS battery failure and the time synchronization service is disabled on the servers. The CMOS battery is a small battery on the motherboard that powers the BIOS settings and keeps track of the date and time when the server is powered off. If the CMOS battery fails, the server will lose its configuration and display an incorrect date and time when it is powered on. This can cause access issues for users and applications that rely on accurate time stamps. The time synchronization service is a service that synchronizes the system clock with a reliable external time source, such as a network time protocol (NTP) server. If the time synchronization service is disabled on the servers, they will not be able to update their clocks automatically and may drift out of sync with each other and with the network. This can also cause access issues for users and applications that require consistent and accurate time across the network.
A server administrator is deploying a new server that has two hard drives on which to install the OS. Which of the following RAID configurations should be used to provide redundancy for the OS?
RAID 1 (mirroring) is a RAID configuration that should be used to provide redundancy for the OS on a server that has two hard drives on which to install the OS. RAID 1 (mirroring) is a configuration that duplicates data across two or more drives. It provides fault tolerance and improves read performance, but reduces storage capacity by half. If one drive fails in RAID 1, the other drive can continue to operate without data loss or system downtime. RAID 0 (striping) is a configuration that splits data across two or more drives without parity or redundancy. It improves performance but offers no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 5 (striping with parity) is a configuration that stripes data across three or more drives with parity information. It provides fault tolerance and improves performance, but reduces storage capacity by one drive's worth of space. RAID 5 can tolerate one drive failure without data loss, but not two ormore. RAID 6 (striping with double parity) is a configuration that stripes data across four or more drives with double parity information. It provides fault tolerance and improves performance, but reduces storage capacity by two drives' worth of space. RAID 6 can tolerate two drive failures without data loss, but not three or more.Reference:https://www.howtogeek.com/199068/how-to-upgrade-your-existing-hard-drive-in-under-an-hour/
