SK0-005 Exam Results

When new RAID controllers are installed and disks go missing, the first logical step is to reboot to the RAID controller BIOS and rescan for attached disks and arrays (Answer A). This will allow the RAID controller to detect the connected drives and rebuild the RAID configuration as expected.

Rebooting to RAID controller BIOS (Answer A): This step ensures that all the attached disks and arrays are properly detected and mapped to the RAID configuration.

Checking UEFI settings (Option B): This might be useful later, but initially, the RAID controller BIOS should be checked first to verify disk detection.

Turning off external arrays (Option C): While this could be helpful in some scenarios, it's not the most efficient first step.

Checking cables (Option D): This could be necessary, but since the controllers were just replaced, software/BIOS configurations should be checked first.

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. References: [CompTIA Server+ Certification Exam Objectives], Domain 6.0: Disaster Recovery, Objective 6.3: Compare and contrast various backup techniques.

Increasing IOPS (input/output operations per second) by implementing flash storage is the most likely solution to resolve a slowdown issue in the storage subsystem of a database server. Flash storage uses solid-state drives (SSDs) that have faster read/write speeds and lower latency than traditional hard disk drives (HDDs). This can improve the performance of database queries and transactions. Implementing deduplication, extending capacity, or reformatting the disk as FAT32 are not likely to resolve the issue, as they do not affect the IOPS of the storage subsystem. References: [CompTIA Server+ Certification Exam Objectives], Domain 3.0: Storage, Objective 3.5: Summarize hardware and features of various storage technologies.

When clients on a different VLAN cannot receive DHCP addresses, it’s often because there is no DHCP helper address configured on the router or switch. A DHCP relay/helper address forwards DHCP requests from clients on the VLAN to the DHCP server, which may reside on a different network.

Confirming the network has a helper address (Answer C): This should be the first step to ensure that DHCP requests from the VLAN are correctly routed to the DHCP server.

Checking client NIC speed (Option A): While important, incorrect NIC speed wouldn't affect the ability to obtain an IP address from DHCP.

Checking NTP server (Option B): Time synchronization is unrelated to DHCP issues.

Authorizing the DHCP server (Option D): This is essential for DHCP operation, but since this is an existing DHCP cluster, the helper address is more likely the issue.
