SK0-005 Exam Dumps - CompTIA Server+ Certification Exam

When new RAID controllers are installed and disks go missing, the first logical step is toreboot 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.

After removing the virus from the server, the administrator should perform the following actions to mitigate the issue from reoccurring and to maintain high availability:

Run a vulnerability scanner on the server to identify any other potential weaknesses or exposures that could be exploited by attackers.

Patch the vulnerability that allowed the virus to infect the server in the first place, using the latest updates from the database software vendor or a trusted source.

Update the antivirus software on the server to ensure it has the most recent virus definitions and can detect and prevent future infections. The other options are either unnecessary or counterproductive for this scenario. Repartitioning the hard drive, reformatting the OS, removing the database software, or air gapping the server from the network would cause downtime and data loss, while enabling a host firewall would not prevent a virus infection from within the network. References: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.2: Given a scenario involving a security threat/vulnerability/risk, implement appropriate mitigation techniques.

Sinceport 3306(MySQL) is open on the local workstation as confirmed by the Nmap scan, the next logical step is to checknetwork firewall rules. It’s possible that the workstation’s firewall or network-level security rules are blocking outbound or inbound traffic on port 3306, which is required for database access.

Edit the network firewall rules (Answer D):Ensuring the firewall allows traffic on port 3306 is the appropriate next step, especially since other workstations are not having the same issue.

Checking the database server (Option A):This is unnecessary because other workstations can access the server, confirming the server itself is functioning correctly.

Changing the database password (Option B):This would not resolve the issue of one workstation being unable to connect while others can.

Opening port 3306 on the server (Option C):The problem isn't server-side since other machines can connect without issue.

If drive C is running out of space and there isunallocated spaceavailable on the disk, the best solution is topartition the unallocated spaceand extend drive C to include the new partition. This can be done without significant downtime and will immediately provide more space for the system.

Partition the unallocated space (Answer E):This is the simplest and least disruptive method to increase the available space on drive C.

Decreasing the page/swap file (Option A):This may free up some space but can negatively impact system performance.

Reformatting (Option B):Reformatting would result in significant downtime and data loss, making it an impractical option.

Whole disk encryption (Option C):This does not solve the issue of disk space.

Enforcing disk quotas (Option D):Disk quotas manage space usage but won’t free up space on drive C.

The IP address configuration that the technician should assign to the new server so the members of the accounting group can access the server is 172.16.25.90/24 for the IP address and 172.16.25.254 for the default gateway. This configuration matches the VLAN identified in the image, which has a network address of 172.16.25.0/24 and a subnet mask of 255.255.255.0. The IP address of the server must be within the same network range as the VLAN, which is from 172.16.25.1 to 172.16.25.254, excluding the network and broadcast addresses (172.16.25.0 and 172.16.25.255). The default gateway of the server must be the same as the VLAN, which is 172.16.25.254, to allow communication with other networks or devices outside the VLAN. References: [CompTIA Server+ Certification Exam Objectives], Domain 4.0: Networking, Objective 4.1: Given a scenario, configure network settings for servers.

The upgrade involves transitioning from 10Gb copper to 25Gb fiber, which requires appropriate network interface hardware:

FCoE (A) - Fibre Channel over Ethernet: This protocol allows Fibre Channel to run over Ethernet networks, but it does not address the physical change from copper to fiber.

VLAN ID (B): VLANs segment networks but do not impact the physical connectivity (copper vs. fiber).

SFP (C) - Small Form-factor Pluggable: SFP transceivers are hot-swappable modules used in network interfaces to support fiber connections. A 25Gb SFP28 transceiver would be required for the transition from 10Gb copper to 25Gb fiber. This is the correct answer.

HBA (D) - Host Bus Adapter: HBAs are typically used for storage connectivity (such as Fibre Channel SANs), not general network upgrades.

Since SFP modules allow servers to support fiber connections, this is the best choice for upgrading from 10Gb copper to 25Gb fiber.

RAID 5offers bothdisk redundancyandmaximum usable disk capacityby using block-level striping with parity. RAID 5 allows one drive to fail while still retaining data, and it uses only one disk’s worth of space for parity, maximizing the usable capacity.

RAID 5 (Answer C):Provides redundancy with only one disk's space used for parity, maximizing storage.

RAID 0 (Option A):Provides no redundancy; if one drive fails, all data is lost.

RAID 1 (Option B):Mirrors data, so redundancy is provided, but only half the capacity is usable.

RAID 10 (Option D):Combines RAID 1 and 0 for high performance and redundancy but requires half the disk space for mirroring.

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:ACrash cartis a physical console that can be connected directly to the server’s video output and keyboard/mouse ports. This is useful in situations where remote management (OOB) is unavailable, allowing the administrator to directly view the server's display and interact with the system during the reboot process.

IP KVM(Keyboard, Video, Mouse) is used for remote management, but the scenario specifically mentions no OOB management.

Virtual administration consoleandSerial connectionscan be used for remote management or console access, but since OOB management is unavailable, a physical crash cart is the appropriate choice.
