• Question 292:

  A server technician is deploying a server with eight hard drives. The server specifications call for a RAID configuration that can handle up to two drive failures but also allow for the least amount of drive space lost to RAID overhead. Which of the following RAID levels should the technician configure for this drive array?

  A. RAID 0
  B. RAID 5
  C. RAID 6
  D. RAID 10
  C. RAID 6

  ---

  Explanation

  The technician should configure RAID 6 for this drive array to meet the server specifications. RAID 6 is a type of RAID level that provides fault tolerance and performance enhancement by using striping and dual parity. Striping means dividing data into blocks and distributing them across multiple disks to increase speed and capacity. Parity means calculating and storing extra information that can be used to reconstruct data in case of disk failure. RAID 6 uses two sets of parity information for each stripe, which are stored on different disks. This way, RAID 6 can handle up to two disk failures without losing any data or functionality. RAID 6 also allows for the least amount of drive space lost to RAID overhead compared to other RAID levels that can handle two disk failures, such as RAID 1+0 or RAID 0+1.

• Question 294:

  After configuring IP networking on a newly commissioned server, a server administrator installs a straight- through network cable from the patch panel to the switch. The administrator then returns to the server to test network connectivity using the ping command. The partial output of the ping and ipconfig commands are displayed below:

  

  The administrator returns to the switch and notices an amber link light on the port where the server is connected. Which of the following is the MOST likely reason for the lack of network connectivity?

  A. Network port security
  B. An improper VLAN configuration
  C. A misconfigured DHCP server
  D. A misconfigured NIC on the server
  D. A misconfigured NIC on the server

  ---

  Explanation

  Some devices, such as network switches, use colors to indicate performance information rather than status information. For example, a network switch may display a green LED on a port if the connection is operating at 1 Gbps but an amber

  LED if the port is operating at 100 Mbps. Check the device's documentation to interpret the colors correctly.

• Question 295:

  A systems administrator is installing Windows on an 8TB drive and would like to create a single 8TB partition on the disk. Which of the following options should the administrator use?

  A. VMFS
  B. ZFS
  C. GPT
  D. MBR
  E. LVM
  C. GPT

  ---

  Explanation

• Question 296:

  A systems administrator is preparing to install two servers in a single rack. The administrator is concerned that having both servers in one rack will increase the chance of power issues due to the increased load. Which of the following should the administrator implement FIRST to address the issue?

  A. Separate circuits
  B. An uninterruptible power supply
  C. Increased PDU capacity
  D. Redundant power supplies
  A. Separate circuits

  ---

  Explanation

  The administrator should implement separate circuits first to address the issue of power issues due to the increased load. Separate circuits are electrical wiring systems that provide independent power sources for different devices or groups of devices. By using separate circuits, the administrator can avoid overloading a single circuit with too many servers and reduce the risk of power outages, surges, or fires. Separate circuits also provide redundancy and fault tolerance, as a failure in one circuit will not affect the other circuit.

• Question 297:

  A server administrator is installing a new server with multiple NICs on it. The Chief Information Officer has asked the administrator to ensure the new server will have the least amount of network downtime but a good amount of network speed. Which of the following best describes what the administrator should implement on the new server?

  A. VLAN
  B. vNIC
  C. Link aggregation
  D. Failover
  C. Link aggregation

  ---

  Explanation

  Link aggregation is the best option to implement on the new server to ensure the least amount of network downtime but a good amount of network speed. Link aggregation is a technique of combining multiple physical network interfaces into one logical interface to increase bandwidth, redundancy, and load balancing. Link aggregation can improve the performance and availability of the server by allowing it to use more than one network path for data transmission and failover in case of link failure. Link aggregation can be implemented using various protocols, such as IEEE 802.3ad (LACP), Cisco EtherChannel, or Linux bonding.

• Question 298:

  An administrator is working locally in a data center with multiple server racks. Which of the following is the best low-cost option to connect to any server while on site?

  A. Crash cart
  B. IPKVM
  C. Remote console access
  D. IPMI
  A. Crash cart

  ---

  Explanation

  A crash cart is the best low-cost option to connect to any server while on site in a data center with multiple server racks. A crash cart is a mobile unit that contains a monitor, a keyboard, a mouse, and cables that can be plugged into any server for direct access and control. A crash cart can be used for troubleshooting, maintenance, or configuration of servers without requiring remote access or network connectivity. A crash cart is also easy to move around and store in a data center.

• Question 299:

  A technician is attempting to log in to a Linux server as root but cannot remember the administrator password. Which of the following is the LEAST destructive method of resetting the administrator password?

  A. Boot using a Linux live CD and mount the hard disk to /mnt. Change to the /mnt/etc directory. Edit the passwd file found in that directory.
  B. Reinstall the OS in overlay mode. Reset the root password from the install GUI screen.
  C. Adjust the GRUB boot parameters to boot into single-user mode. Run passwd from the command prompt.
  D. Boot using a Linux live CD and mount the hard disk to /mnt. SCP the /etc directory from a known accessible server to /mnt/etc.
  C. Adjust the GRUB boot parameters to boot into single-user mode. Run passwd from the command prompt.

  ---

  Explanation

  The least destructive method of resetting the administrator password would be option C, adjusting the GRUB boot parameters to boot into single-user mode and running passwd from the command prompt. This method allows the technician to

  reset the root password without making any changes to the system's configuration files or reinstalling the operating system.

  Option A involves editing the system's passwd file, which could potentially cause issues with user accounts and permissions.

  Option B involves reinstalling the OS, which is a very destructive method and would result in data loss and a complete reset of the system.

  Option D involves copying system configuration files from another server, which could potentially introduce new problems and is not a recommended method for resetting the root password.

• Question 300:

  A user can successfully connect to a database server from a home office but is unable to access it from a hotel room. Which of the following authentication methods is most likely configured?

  A. Delegation
  B. Role-based
  C. Rule-based
  D. Scope-based
  D. Scope-based

  ---

  Explanation

  Scope-based authentication is a method of restricting access to resources based on the location, network, or device of the user. It can be used to prevent unauthorized access from outside the organization's network or from

  untrusted devices. In this case, the user can connect to the database server from the home office, which is likely within the scope of the authentication policy, but not from the hotel room, which is outside the scope.
