  References:Event logsare the primary source for tracking server reboots and other system events. Logs such as the system log in Linux (/var/log/syslog or

  /var/log/messages) or the Event Viewer in Windows provide timestamps and details about shutdowns, restarts, and boot processes. Regular monitoring ensures that unplanned reboots or system errors are identified and addressed.

  Uptime:Indicates how long the server has been running since the last reboot but does not provide detailed reboot evidence.

  IOPS:Refers to input/output operations per second, unrelated to reboots.

  CPU utilization:Reflects processor activity but offers no reboot evidence.

• Question 272:

  An administrator is alerted to an issue with server hardware deployed as a virtualization host. The alert indicates a predictive failure in a DIMM module. Which of the following is the BEST action for the administrator to take?

  A. Replace the failed module during the next scheduled downtime.
  B. Hot swap the failed module immediately.
  C. Schedule an outage to replace the failed module immediately.
  D. Hot swap the failed module during the next scheduled downtime.
  A. Replace the failed module during the next scheduled downtime.

• Question 273:

  A USB drive has been purchased to move files between Windows, *nix, and Macintosh servers. Which of the following filesystems is the BEST choice to ensure the drive can read and be written to by all of the servers?

  A. ext2
  B. FAT32
  C. NTFS
  D. UFS
  B. FAT32

• Question 274:

  A technician is configuring a server with eight available drive bays. The technician wants a combination of the most redundancy and the maximum available storage.

  Which of the following RAID levels should the technician use?

  A. RAID 1
  B. RAID 5
  C. RAID 6
  D. RAID 10
  D. RAID 10

  ---

  Explanation

  When selecting a RAID level, both redundancy and storage efficiency must be considered:

  RAID 1 mirrors data, providing high redundancy but reducing available storage to 50%. With eight drives, only four drives' worth of space would be available. RAID 5 uses striping with distributed parity. It provides good storage efficiency (n-1)

  but can only tolerate one drive failure.

  RAID 6 is similar to RAID 5 but uses dual parity, allowing two drives to fail while still maintaining data integrity. However, it reduces available storage to (n-2). RAID 10 (also known as RAID 1+0) combines mirroring and striping. It provides

  excellent redundancy and performance, allowing multiple drive failures as long as they aren't in the same mirrored pair. Storage efficiency is 50%, but the redundancy and performance benefits outweigh this trade-off in high-availability

  environments.

  Since the technician requires both maximum redundancy and high available storage, RAID 10 is the best choice.

• Question 275:

  A technician is installing an OS on ten servers. Which of the following media installation types would allow for the fastest installation time?

  A. Network
  B. Embedded
  C. Optical
  D. USB
  A. Network

  ---

  Explanation

  Network Installation: Allows the OS image to be deployed from a central server, streamlining deployment across multiple systems simultaneously. This is significantly faster than individual installations from other media.

• Question 276:

  An administrator has been asked to disable CPU hyperthreading on a server to satisfy a licensing issue. Which of the following best describes how the administrator will likely perform this action?

  A. Use an RDP/VNC session.
  B. Modify the startup configuration.
  C. Use a PowerShell/Bash script.
  D. Use the BIOS/UEFI setup.
  D. Use the BIOS/UEFI setup.

• Question 277:

  Which of the following ensures a secondary network path is available if the primary connection fails?

  A. Link aggregation
  B. Most recently used
  C. Heartbeat
  D. Fault tolerance
  D. Fault tolerance

  ---

  Explanation

  Fault tolerance is the ability of a system to continue functioning in the event of a failure of one or more of its components. Fault tolerance can ensure a secondary network path is available if the primary connection fails. Fault tolerance can be

  achieved by using redundant components, such as network cards, cables, switches, routers, etc., that can take over the function of the failed component without interrupting the service.

• Question 278:

  HOTSPOT

  A systems administrator deployed a new web proxy server onto the network. The proxy server has two interfaces: the first is connected to an internal corporate firewall, and the second is connected to an internet-facing firewall. Many users at the company are reporting they are unable to access the Internet since the new proxy was introduced. Analyze the network diagram and the proxy server’s host routing table to resolve the Internet connectivity issues.

  INSTRUCTIONS

  Perform the following steps:

  1.Click on the proxy server to display its routing table.

  2.Modify the appropriate route entries to resolve the Internet connectivity issue.

• Question 279:

  A technician needs to install a Type 1 hypervisor on a server. The server has SD card slots, a SAS controller, and a SATA controller, and it is attached to a NAS. On which of the following drive types should the technician install the hypervisor?

  A. SD card
  B. NAS drive
  C. SATA drive
  D. SAS drive
  D. SAS drive

  ---

  Explanation

  The technician should install the Type 1 hypervisor on a SAS drive. A Type 1 hypervisor is a layer of software that runs directly on top of the physical hardware and creates virtual machines that share the hardware resources. A Type 1 hypervisor requires fast and reliable storage for optimal performance and stability. A SAS drive is a type of hard disk drive that uses Serial Attached SCSI (SAS) as its interface protocol. SAS drives offer high speed, low latency, and high reliability compared to other types of drives, such as SD cards, NAS drives, or SATA drives. SD cards are flash memory cards that offer low cost and portability but have low speed, low capacity, and low durability. NAS drives are network-attached storage devices that offer high capacity and easy access but have high latency and low reliability due to network dependency. SATA drives are hard disk drives that use Serial ATA (SATA) as their interface protocol. SATA drives offer moderate speed, moderate cost, and moderate reliability but have lower performance and durability than SAS drives.

• Question 280:

  An administrator is troubleshooting a server that is rebooting and crashing. The administrator notices that the server is making sounds that are louder than usual. Upon closer inspection, the administrator discovers that the noises are coming from the front of the chassis. Which of the following is the most likely reason for this behavior?

  A. One of the fans has failed.
  B. The power supply has failed.
  C. The RAM is malfunctioning.
  D. The CPU is overheating.
  A. One of the fans has failed.

  ---

  Explanation

  A server has multiple fans inside the chassis to cool down the components and prevent overheating. If one of the fans fails, it can cause the server to reboot and crash due to thermal issues. A failed fan can also make loud noises due to friction or vibration. The administrator should check the fans and clean them from dust and debris, or replace them if they are damaged12.
