• Question 431:

  Alter rack mounting a server, a technician must install four network cables and two power cables for the server. Which of the following is the MOST appropriate way to complete this task?

  A. Wire the four network cables and the two power cables through the cable management arm using appropriate-length cables.
  B. Run the tour network cables up the left side of the rack to the top of the rack switch. Run the two power cables down the right side of the rack toward the UPS.
  C. Use the longest cables possible to allow for adjustment of the server rail within the rack.
  D. Install an Ethernet patch panel and a PDU to accommodate the network and power cables.
  B. Run the tour network cables up the left side of the rack to the top of the rack switch. Run the two power cables down the right side of the rack toward the UPS.

  ---

  Explanation

  This is the most appropriate way to complete the task because it follows the best practices of cable management. Cable management is a process of organizing and securing cables in a rack or a server room to improve airflow, accessibility,

  safety, and aesthetics. Running the network cables up the left side and the power cables down the right side of the rack helps to avoid cable clutter, interference, and confusion. It also makes it easier to trace and troubleshoot cables if

  needed. Using appropriate-length cables also helps to reduce cable slack and excess. Wiring the cables through the cable management arm may cause stress and damage to the cables when moving the server in or out of the rack. Using the

  longest cables possible may create cable loops and tangles that can block airflow and increase fire hazards. Installing an Ethernet patch panel and a PDU (Power Distribution Unit) may be useful for accommodating more network and power

  cables, but not necessary for a single server.

• Question 432:

  A VLAN needs to be configured within a virtual environment for a new VM. Which of the following will ensure the VM receives a correct IP address?

  A. A virtual router
  B. A host NIC
  C. AVPN
  D. A virtual switch
  E. A vNIC
  E. A vNIC

  ---

  Explanation

  E. A vNIC (virtual network interface card) is what connects a VM to a virtual network, and it is responsible for sending and receiving network traffic. When a VLAN needs to be configured within a virtual environment for a new VM, creating a vNIC with the correct VLAN configuration will ensure that the VM receives a correct IP address within that VLAN. The virtual switch is what connects the vNIC to the physical network, and a virtual router may be necessary if the VLAN is to communicate with other networks or the Internet, but neither of these options specifically ensures that the VM receives a correct IP address. AVPN (Amazon Virtual Private Network) is a networking solution provided by Amazon Web Services and is not relevant to this scenario unless the virtual environment is hosted on AWS. A host NIC (network interface card) is a physical network adapter on the host machine and is not directly related to configuring a VLAN for a virtual environment.

• Question 433:

  The management team at a healthcare organization is concerned about being able to access the daily vital records if there is an IT disaster that causes both servers and the network to be offline. Which of the following backup types can the organization use to mitigate this risk?

  A. Tape
  B. Cloud
  C. Disk
  D. Print
  B. Cloud

  ---

  Explanation

  This is a type of backup that can mitigate the risk of being unable to access the daily vital records if there is an IT disaster that causes both servers and the network to be offline. A cloud backup means that the data is copied and stored on a remote cloud server that can be accessed over the internet. A cloud backup offers the benefits of off-site data protection, scalability, reliability, and cost-effectiveness, but may have less control, security, and performance than other backup types.

• Question 434:

  A technician is configuring a server that will need to accommodate a planned network upgrade. All hosts will be changed from 10Gb copper to 25Gb fiber.

  Which of the following would best suit the requirements?

  A. FCoE
  B. VLAN ID
  C. SFP
  D. HBA
  C. SFP

  ---

  Explanation

  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.

• Question 435:

  A server administrator made a change in a server's BIOS in an attempt to fix an issue with the OS not turning on. However, the change did not successfully correct the issue. Which of the following should the server administrator do NEXT?

  A. Reinstall the server OS in repair mode while maintaining the data.
  B. Flash the BIOS with the most recent version.
  C. Reverse the latest change made to the server and reboot.
  D. Restart the server into safe mode and roll back changes.
  C. Reverse the latest change made to the server and reboot.

  ---

  Explanation

  The best practice for troubleshooting is to follow a logical and systematic process that involves identifying the problem, establishing a theory of probable cause, testing the theory, establishing a plan of action, implementing the solution,

  verifying functionality, and documenting findings. Since the problem occurred after a change in the server's BIOS, the most likely cause is that the change was incompatible or incorrect for the OS. Therefore, the next step should be to reverse

  the latest change made to the server and reboot to see if that fixes the issue.

• Question 436:

  A technician is trying to reach abc.intranet.com but is unable to do so by name. The technician is able to reach it by IP address, though. Which of the following is MOST likely misconfigured ?

  A. The VLAN
  B. The DNS
  C. The subnet mask
  D. The default gateway
  B. The DNS

  Explanation

• Question 437:

  An administrator is troubleshooting a RAID issue in a failed server. The server reported a drive failure, and then it crashed and would no longer turn on. There are two arrays on the failed server: a two-drive RAID 0 set for the OS, and an eight-drive RAID 10 set for data.

  Which of the following failure scenarios MOST likely occurred?

  A. A drive failed in the OS array.
  B. A drive failed and then recovered in the data array.
  C. A drive failed in both of the arrays.
  D. A drive failed in the data array.
  A. A drive failed in the OS array.

  ---

  Explanation

  If a server has two arrays on the failed server: a two-drive RAID 0 set for the OS, and an eight-drive RAID 10 set for data, then the most likely failure scenario that caused the server to crash and not boot is that a drive failed in the OS array. RAID 0 is a RAID configuration that stripes data across two or more drives without parity or redundancy. RAID 0 offers high performance but no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 10 is a RAID configuration that combines disk mirroring and disk striping with parity. RAID 10 offers high performance and fault tolerance. RAID 10 can tolerate up to one drive failure per mirrored pair without losing data or functionality.

• Question 438:

  After installing an OS on a new server, the administrator realizes the server does not have any network connectivity. The administrator checks the network cable, and it seems to be transferring data.

  Which of the following should be checked next?

  A. NIC firmware
  B. IPv4 options
  C. DHCP options
  D. Firewall options
  E. DNS settings
  B. IPv4 options

  ---

  Explanation

  If the network cable is functioning but there is no network connectivity, the next step would be to check theIPv4 options. This includes verifying that the server has a correct IP address, subnet mask, and gateway configuration.

  IPv4 options (Answer B):Incorrect IP configuration is a common reason for network connectivity issues.

  NIC firmware (Option A):Firmware issues are less likely if the NIC is detecting the cable and appears operational.

  DHCP options (Option C):DHCP could be checked if automatic IP assignment is being used, but verifying IPv4 options manually is the first step.

  Firewall options (Option D):Firewalls can block connectivity but should be checked after confirming IP settings.

  DNS settings (Option E):DNS issues usually affect domain name resolution, not basic network connectivity.

  This topic is covered underSK0-005 Objective 3.1: Install and configure server components.

• Question 439:

  A technician needs maximum power redundancy while configuring a new server rack. Which of the following should be specified? (Select two).

  A. Separate circuits
  B. Rack balancing
  C. Blanking panels
  D. High-voltage PDUs
  E. KVM placement
  F. Multiple UPSs
  A. Separate circuits
  F. Multiple UPSs

  ---

  Explanation

  Separate circuits and multiple UPSs can provide fail-safe power redundancy for a server rack. Separate circuits mean that the server rack is connected to two or more independent power sources, such as different utility lines or generators. This can prevent a single point of failure in the power supply, as if one circuit goes down, the other circuit can still provide power to the server rack1. Multiple UPSs mean that the server rack has two or more uninterruptible power supplies, which are devices that provide backup power and surge protection in case of a power outage or fluctuation. Multiple UPSs can be connected to separate circuits, or to different outlets on the same circuit, to increase the reliability and availability of power for the server rack23.
