CompTIA CompTIA Certifications SK0-005 Questions & Answers

• Question 251:

  A technician has received multiple reports of issues with a server. The server occasionally has a BSOD, powers off unexpectedly, and has fans that run continuously. Which of the following BEST represents what the technician should investigate during troubleshooting?

  A. Firmware incompatibility

  B. CPU overheating

  C. LED indicators

  D. ESD issues

  Correct Answer: B

  Unexpected shutdowns. If the system is randomly shutting down or rebooting, the most likely cause is a heat problem.

  B. Assign individual permissions on the folder to each user.

  C. Create a group that includes all users and assign the proper permissions.

  D. Assign ownership on the folder for each user.

• Question 253:

  Users at a company work with highly sensitive data. The security department implemented an administrative and technical control to enforce least-privilege access assigned to files. However, the security department has discovered unauthorized data exfiltration.

  Which of the following is the BEST way to protect the data from leaking?

  A. Utilize privacy screens.

  B. Implement disk quotas.

  C. Install a DLP solution.

  D. Enforce the lock-screen feature.

  Correct Answer: C

  The best way to protect the data from leaking is to install a DLP solution. A DLP (Data Loss Prevention) solution is a software that helps businesses prevent confidential data from being leaked or stolen by unauthorized parties. A DLP solution can identify, monitor, and protect data as it moves across networks and devices, such as endpoints, email, web, cloud applications, or removable media. A DLP solution can also enforce security policies based on content and context for data in use, in motion, and at rest. A DLP solution can detect and prevent data breaches by using various techniques, such as content inspection, contextual analysis, encryption, blocking, alerting, warning, quarantining, or other remediation actions.

• Question 254:

  An administrator is configuring a server to communicate with a new storage array. To do so, the administrator enters the WWPN of the new array in the server's storage configuration. Which of the following technologies is the new connection using?

  A. iSCSI

  B. eSATA

  C. NFS

  D. FCoE

  Correct Answer: D

  A very common interface for storage in servers is a Fibre Channel interface. These are used to connect devices in a high-speed fiber storage network. These networks typically use a fiber switch with devices connected to the switch using Fibre Channel interfaces. Servers will require some implementation of a fiber HBA. Each HBA has a unique World Wide Name (WWN), which like a MAC address uses an organizationally unique identifier (OUI) assigned by the IEEE. An example of a fiber switch to which the cables from the HBAs on the servers would attach.

• Question 255:

  A server technician installs a new NIC on a server and configures the NIC for IP connectivity. The technician then tests the connection using the ping command. Given the following partial output of the ping and ipconfig commands:

  

  Which of the following caused the issue?

  A. Duplicate IP address

  B. Incorrect default gateway C. DHCP misconfiguration

  D. Incorrect routing table

  Correct Answer: A

  The ping command output shows that the NIC has an IP address of 192.168.1.100 and a default gateway of 192.168.1.1. However, when the technician tries to ping the default gateway, the reply comes from another IP address:

  192.168.1.101. This means that there is another device on the network that has the same IP address as the default gateway, and it is responding to the ping request instead of the intended destination.

  A duplicate IP address can cause network connectivity problems, such as packet loss, routing errors, or unreachable hosts. To resolve this issue, the technician should either change the IP address of the default gateway or the device that is

  conflicting with it, or use DHCP to assign IP addresses automatically and avoid conflicts.

  The other options are not correct because they do not explain the ping output. An incorrect default gateway would cause no reply or a destination unreachable message, not a reply from a different IP address. A DHCP misconfiguration would

  cause an invalid or no IP address on the NIC, not a duplicate IP address on the network. An incorrect routing table would cause routing errors or unreachable destinations, not a reply from a different IP address.

• Question 256:

  A systems administrator needs to configure a new server and external storage for a new production application environment. Based on end-user specifications, the new solution needs to adhere to the following basic requirements:

  1.

  The OS must be installed in a separate disk partition. In case of hard drive failure, it cannot be affected.

  2.

  Application data IOPS performance is a must.

  3.

  Data availability is a high priority, even in the case of multiple hard drive failures.

  Which of the following are the BEST options to comply with the user requirements? (Choose three.)

  A. Install the OS on a RAID 0 array.

  B. Install the OS on a RAID 1 array.

  C. Configure RAID 1 for the application data.

  D. Configure RAID 5 for the application data.

  E. Use SSD hard drives for the data application array.

  F. Use SATA hard drives for the data application array.

  G. Use a single JBOD for OS and application data.

  Correct Answer: BCE

  1.

  The OS must be installed in a separate disk partition. In case of hard drive failure, it cannot be affected. = RAID 1

  2.

  Application data IOPS performance is a must. = SSD

  3.

  Data availability is a high priority, even in the case of multiple hard drive failures.= RAID 1, RAID 6 writes parity information across the drives as is done in RAID 5, but it writes two stripes, which allows the system to recover from two drive failures whereas RAID 5 cannot.

• Question 257:

  A server administrator is testing a disaster recovery plan. The test involves creating a downtime scenario and taking the necessary steps. Which of the following testing methods is the administrator MOST likely performing?

  A. Backup recovery

  B. Simulated

  C. Tabletop

  D. Live failover

  Correct Answer: B

• Question 258:

  Which of the following relates to how much data loss a company agrees to tolerate in the event of a disaster?

  A. RTO

  B. MTBF

  C. PRO

  D. MTTR

  Correct Answer: A

  The Recovery Time Objective (RTO) is the maximum amount of time that a company agrees to tolerate in the event of a disaster before restoring its normal operations. The RTO is based on the business impact analysis (BIA) and the criticality of the processes and data involved. The RTO helps determine the backup and recovery strategies and resources needed to minimize downtime and data loss.

• Question 259:

  A server administrator must respond to tickets within a certain amount of time. The server administrator needs to adhere to the:

  A. BIA.

  B. RTO.

  C. MTTR.

  D. SLA.

  Correct Answer: D

  The server administrator needs to adhere to the Service Level Agreement (SLA) when responding to tickets within a certain amount of time. An SLA is a contract between a service provider and a customer that defines the quality, availability, and responsibilities of the service. An SLA may specify the response time for tickets, as well as other metrics such as uptime, performance, security, and backup frequency.

• Question 260:

  A server administrator is swapping out the GPU card inside a server. Which of the following actions should the administrator take FIRST?

  A. Inspect the GPU that is being installed.

  B. Ensure the GPU meets HCL guidelines.

  C. Shut down the server.

  D. Disconnect the power from the rack.

  Correct Answer: C

  The first action that the administrator should take before swapping out the GPU card inside a server is to shut down the server. This is to ensure that the server is not running any processes that might be using the GPU card, and to prevent

  any damage to the hardware or data loss due to sudden power loss. Shutting down the server also reduces the risk of electrostatic discharge (ESD) that might harm the components.
