CompTIA CompTIA Certifications SK0-005 Questions & Answers

• Question 391:

  A server technician notices several of the servers in a data center are making loud noises. The servers are still working correctly, and no indicator lights show any issues. Which of the following should the technician do first to ensure the issues are corrected and the servers remain online?

  A. Replace the drives.

  B. Upgrade the firmware.

  C. Establish a remote connection to the server.

  D. Replace the fans.

  Correct Answer: A

  The loud noises from the servers are most likely caused by failing hard disk drives, which can produce clicking or grinding sounds. Replacing the drives with new ones can prevent data loss and downtime. Replacing the drives can be done without shutting down the server if they are hot-swappable, which means they can be removed and inserted while the server is running.

• Question 392:

  A server administrator is reviewing the following specifications:

  VM01 Host:

  CPU: 2 Physical, 4 Cores

  RAM: 16GB

  Storage: 16TB

  Server 1 on VM01:

  CPU: 1 virtual socket, 1 core per socket

  RAM: 4GB Storage: 8TB

  Server 2 on VM01:

  CPU: 2 virtual sockets, 2 cores per socket

  RAM: 8GB

  Storage: 10TB

  Which of the following is described given these specifications?

  A. Virtual switch

  B. Host vs. guest

  C. Overprovisioning

  D. Scalability

  Correct Answer: C

  Overprovisioning is a situation where the allocated resources for a virtual machine exceed the available resources of the physical host. In this case, the storage allocated for Server 1 and Server 2 on VM01 is 8TB and 10TB respectively,

  which adds up to 18TB. However, the storage available on the VM01 host is only 16TB, which means there is a 2TB deficit. This can cause performance issues and errors for the virtual machines.

• Question 393:

  Corporate policy mandates that logs from all servers be available for review regardless of the state of the server. Which of the following must be configured to comply with this policy?

  A. Aggregation

  B. Subscription

  C. Merging

  D. Collection

  Correct Answer: A

  Aggregation is the process of collecting, standardizing, and consolidating log data from multiple sources into a central location. Aggregation makes it easier to search, analyze, and report on log data, as well as to comply with security policies and regulations. By aggregating logs from all servers, regardless of their state, the corporate policy can ensure that no log data is lost or inaccessible in case of a server failure or outage

• Question 394:

  After a technician upgrades the firmware on a database server that is connected to two external storage arrays, the server prompts the technician to configure RAID. The technician knows the server had several configured RAID sets and thinks the firmware upgrade cleared the RAID configurations. Which of the following should the technician do to troubleshoot this issue?

  A. Power cycle the storage arrays and rescan RAID on the server.

  B. Boot the OS into recovery mode and rescan the disks.

  C. Restore the default RAID configuration and reboot.

  D. Perform a rescan on the server's RAID controller.

  Correct Answer: D

  A rescan on the server's RAID controller is a possible troubleshooting step to detect the existing RAID configurations on the connected storage arrays. A firmware upgrade may cause the RAID controller to lose the RAID metadata or settings, and a rescan may restore them. A rescan is preferable to restoring the default RAID configuration, as the latter may erase the existing data on the arrays. Power cycling the storage arrays or booting the OS into recovery mode may not help if the RAID controller does not recognize the RAID sets. References: CompTIA Server+ Study Guide, Chapter 7: Storage, page 287.

• Question 395:

  Which of the following life-cycle management phases deals with a server that is no longer in operation?

  A. End-of-life

  B. Disposal

  C. Usage

  D. Procurement

  Correct Answer: A

  End-of-life is the phase of lifecycle management that deals with a server that is no longer in operation. End-of-life means that the server has reached the end of its useful life and is no longer supported by the manufacturer or the service provider. End-of-life may also imply that the serveris obsolete, incompatible, or inefficient for the current needs and standards1. End-of-life servers may be decommissioned, recycled, donated, or disposed of according to the organizational policies and environmental regulations

• Question 396:

  An administrator is troubleshooting a failed NIC in an application server. The server uses DHCP to get all IP configurations, and the server must use a specific IP address. The administrator replaces the NIC, but then the server begins to receive a different and incorrect IP address. Which of the following will enable the server to get the proper IP address?

  A. Modifying the MAC used on the DHCP reservation

  B. Updating the local hosts file with the correct IP address

  C. Modifying the WWNN used on the DHCP reservation

  D. Updating the NIC to use the correct WWNN

  Correct Answer: A

  A DHCP reservation is a way to assign a specific IP address to a device based on its MAC address, which is a unique identifier for each network interface card (NIC). When the administrator replaced the NIC, the MAC address of the server changed, and the DHCP server no longer recognized it as the same device. Therefore, the DHCP server assigned a different IP address to the server, which was incorrect for the application. To fix this problem, the administrator needs to modify the DHCP reservation to use the new MAC address of the NIC, so that the server can get the proper IP address. A WWNN (World Wide Node Name) is a unique identifier for a Fibre Channel node, which is a device that can communicate over a Fibre Channel network. A WWNN is not related to DHCP or IP addresses, and it is not used for DHCP reservations. Therefore, options B and D are incorrect. Updating the local hosts file with the correct IP address (option C) is also incorrect, because it does not solve the problem of getting the correct IP address from the DHCP server. The hosts file is a local file that maps hostnames to IP addresses, and it is used to override DNS queries. However, it does not affect how the DHCP server assigns IP addresses to devices. Moreover, updating the hosts file manually on every device that needs to communicate with the server is not a scalable or efficient solution.

• Question 397:

  A Linux server requires repetitive tasks for reconfiguration. Which of the following would be the best scripting language to use?

  A. PowerShell

  B. Batch command file

  C. Bash

  D. Visual Basic

  Correct Answer: C

  Explanation: Bash is a scripting language that is commonly used in Linux systems to automate tasks and manipulate text. Bash scripts can run commands, variables, functions, loops, and conditional statements. PowerShell is a scripting language that is mainly used in Windows systems, while batch command files are simple text files that contain a series of commands to be executed by the command-line interpreter. Visual Basic is a programming language that is used to create applications, not scripts.

• Question 398:

  An administrator is able to ping the default gateway and internet sites byname from a file server. The file server is not able to ping the print server by name. The administrator is able to ping the file server from the print server by both IP address and computer name. When initiating an initiating from the file server for the print server, a different IP address is returned, which of the following is MOST Likely the cause?

  A. A firewall blockingthe ICMP echo reply.

  B. The DHCP scope option is incorrect

  C. The DNS entriesforthe print server are incorrect.

  D. The hosts file misconfigured.

  Correct Answer: D

  Explanation: The hosts file is a file that maps hostnames to IP addresses on a server or a computer. It can be used to override or supplement the DNS (Domain Name System) resolution for certain hosts or domains. If the hosts file is misconfigured, it may return a different IP address for a hostname than the one registered in the DNS server, causing connectivity issues or errors.

• Question 399:

  A new 40GB NIC has just been installed in a server but is not detected within the Windows server OS. Which of the following would most likely fix the issue?

  A. Update the firmware on the NIC.

  B. Update the server OS.

  C. Update the remote management console.

  D. Update the switch firmware.

  Correct Answer: A

  Explanation: Updating the firmware on the NIC is the most likely solution to fix the issue of a new 40GB NIC not being detected within the Windows server OS. Firmware is a softwareprogram that controls the functionality of a hardware device, such as a NIC (network interface card). A NIC is a device that enables network communication for a server by providing an interface between the server and the network cable or wireless connection. Updating the firmware on the NIC can improve its performance, compatibility, and stability with the server OS and network protocols.

• Question 400:

  A company created a new DR plan. The management team would like to begin performing a review of this plan without endangering company data and with a minimal time commitment. Which of the following testing methods would best allow for this type of review?

  A. Simulated

  B. Tabletop

  C. Live

  D. Non-production

  Correct Answer: B

  Tabletop testing is a method of reviewing a DR plan without endangering company data and with a minimal time commitment. Tabletop testing involves a simulated scenario where the participants discuss their roles and responsibilities, identify potential issues, and evaluate the effectiveness of the plan. Simulated, live, and non-production testing are methods that involve more time and resources, and may pose some risks to company data.
