CompTIA SK0-005 Online Questions & Answers

• Question 391:

  A server technician has been asked to upload a few files from the internal web server to the internal FTP server. The technician logs in to the web server using PuTTY, but the connection to the FTP server fails. However, the FTP connection from the technician's workstation is sucessful. To troubleshoot the issue, the technician executes the following command on both the web server and the workstation:

  ping ftp.acme.local

  The IP address in the command output is different on each machine. Which of the following is the MOST likely reason for the connection failure?

  A. A misconfigured firewall
  B. A misconfigured hosts.deny file
  C. A misconfigured hosts file
  D. A misconfigured hosts.allow file
  C. A misconfigured hosts file

  ---

  Explanation

  Remove PuTTY from the question it's intended as a distraction. The key is "ping ftp.acme.local The IP address in the command output is different on each machine." hosts.allow and hosts.deny are for ACL not direction a host file that is different on each machine would cause the IP address to be different

• Question 392:

  An administrator has set up a GPO to disable USB drive access on a company's servers. The GPO is set up as a computer con guration policy and does not use security groups ltering. The administrator is testing to ensure the policy is working correctly. A server in the accounting OU works as expected, but a server in the sales OU is still allowing access to USB drives. The administrator runs the gpupdate /force command and tries again; however, the server still allows access to the USB drive.

  Which of the following is the MOST likely cause?

  A. The WMI filter is not configured properly.
  B. Item-level targeting is not configured properly.
  C. The scope is not configured properly.
  D. Loopback processing is not configured properly.
  B. Item-level targeting is not configured properly.

• Question 393:

  A technician notices a server that contains four fans is now louder than normal even though the temperature in the room has not changed and the load on the server has not increased.

  Which of the following is most likely the cause of the noise?

  A. Defective fan
  B. Change in UEFI
  C. Unseated drive
  D. Firmware upgrade needed
  A. Defective fan

  ---

  Explanation

  A sudden increase in fan noise without any changes in temperature or server workload is typically due to a defective fan.

  If one fan fails, the remaining fans will automatically increase their speed to compensate for the loss, leading to increased noise levels. Servers use intelligent fan control systems, which monitor temperature and fan health. If a fan stops

  functioning properly, the others will ramp up to maintain adequate cooling.

  This issue can be resolved by inspecting and replacing the defective fan to restore normal cooling operation.

• Question 394:

  A systems administrator is provisioning a large number of virtual Linux machines that will be configured identically. The administrator would like to configure the machines quickly and easily but does not have access to an automation/ orchestration platform. Additionally, the administrator would like to set up a system that can be used in the future, even on newer versions of the OS.

  Which of the following will best meet the administrator's requirements?

  A. Deploying each server from a VM template
  B. Using a kickstart file during installation
  C. Configuring each server manually one at a time
  D. Copying/pasting configuration commands into each server through SSH sessions
  E. Configuring a single server and then creating clones of it
  B. Using a kickstart file during installation

  ---

  Explanation

  Kickstart Files (Linux): Kickstart files are configuration files that automate the Linux installation process. They contain pre-determined answers to installation prompts, allowing for identical and rapid deployment of multiple systems. (CompTIA Server+ Objectives SK0-004: 3.1, Red Hat documentation on Kickstart: https://access.redhat.com/documentation/) Why other options are less ideal:

• Question 395:

  A systems administrator is attempting to connect via RDP to a server that is running Windows. However, the systems administrator cannot connect to the machine via RDP to reboot it and apply updates. Which of the following methods should be used to access the machine and perform a reboot if the server is not physically accessible?

  A. ILO/iDRAC
  B. TCP/IP
  C. SSH/SCP
  D. VNC/VPN
  A. ILO/iDRAC

• Question 396:

  An administrator is configuring a server that will host a high-performance financial application. Which of the following disk types will serve this purpose?

  A. SAS SSD
  B. SATA SSD
  C. SAS drive with 10000rpm
  D. SATA drive with 15000rpm
  A. SAS SSD

  ---

  Explanation

  The best disk type for a high-performance financial application is a SAS SSD. A SAS SSD (Serial Attached SCSI Solid State Drive) is a type of storage device that uses flash memory chips to store data and has a SAS interface to connect to a server or a storage array. A SAS SSD offers high speed, low latency, high reliability, and high durability compared to other types of disks, such as SATA SSDs, SAS HDDs, or SATA HDDs. A SAS SSD can handle high I/O workloads and deliver consistent performance for applications that require fast data access and processing.

• Question 397:

  A technician is connecting a server's secondary NIC to a separate network. The technician connects the cable to the switch but then does not see any link lights on the NIC. The technician confirms there is nothing wrong on the network or with the physical connection. Which of the following should the technician perform NEXT?

  A. Restart the server
  B. Configure the network on the server
  C. Enable the port on the server
  D. Check the DHCP configuration
  C. Enable the port on the server

  ---

  Explanation

  The next thing that the technician should perform is to enable the port on the server. A port is a logical endpoint that identifies a specific service or application on a network device. A port can be enabled or disabled depending on whether the service or application is running or not. If a port is disabled on a server, it means that the server cannot send or receive any network traffic on that port, which can prevent communication with other devices or services that use that port. In this case, if port 389 is disabled on the server, it means that the server cannot use LDAP to access or modify directory services over a network. To resolve this issue, the technician should enable port 389 on the server using commands such as netsh or iptables.

• Question 398:

  Which of the following BEST describes the concept of right to downgrade?

  A. It allows for the return of a new OS license if the newer OS is not compatible with the currently installed software and is returning to the previously used OS
  B. It allows a server to run on fewer resources than what is outlined in the minimum requirements document without purchasing a license
  C. It allows for a previous version of an OS to be deployed in a test environment for each current license that is purchased
  D. It allows a previous version of an OS to be installed and covered by the same license as the newer version
  D. It allows a previous version of an OS to be installed and covered by the same license as the newer version

  ---

  Explanation

  The concept of right to downgrade allows a previous version of an OS to be installed and covered by the same license as the newer version. For example, if a customer has a license for Windows 10 Pro, they can choose to install Windows

  8.1 Pro or Windows 7 Professional instead and still be compliant with the license terms. Downgrade rights are granted by Microsoft for certain products and programs, such as Windows and Windows Server software acquired through Commercial Licensing, OEM, or retail channels. Downgrade rights are intended to provide customers with flexibility and compatibility when using Microsoft software.

• Question 399:

  Which of the following should a technician verify FIRST before decommissioning and wiping a file server?

  A. The media destruction method
  B. The recycling policy
  C. Asset management documentation
  D. Non-utilization
  C. Asset management documentation
