CompTIA SK0-005 Online Questions & Answers

• Question 281:

  A software developer is unable to reach an internal website. The developer's attempt to ping the FQDN returns the following IP address: 104.18.17.32. Which of the following is the most likely reason for this result?

  A. The NIC is set to DHCP.
  B. The default gateway is misconfigured.
  C. The primary DNS server is 8.8.8.8.
  D. There is a manual entry in the hosts file.
  D. There is a manual entry in the hosts file.

  ---

  Explanation

  The most likely reason for this result is that there is a manual entry in the hosts file that maps the FQDN to an incorrect IP address (104.18.17.32). The hosts file is a text file that contains mappings of hostnames or domain names to IP

  addresses, which are used by the operating system to resolve names before querying DNS servers on the network or internet. The hosts file can be used to override DNS settings or block access to certain websites by redirecting them to

  different IP addresses, such as localhost (127.O.O.l) or invalid addresses (O.O.O.O). If there is a manual entry in the hosts file that conflicts with DNS records, it can cause name resolution errors or connectivity issues.

• Question 282:

  An administrator is deploying a new secure web server. The only administration method that is permitted is to connect via RDP. Which of the following ports should be allowed? (Select two).

  A. 53
  B. 80
  C. 389
  D. 443
  E. 445
  F. 3389
  G. 8080
  D. 443
  F. 3389

  ---

  Explanation

  Port 443 is used for HTTPS, which is a secure version of HTTP that encrypts the data between the web server and the client. Port 3389 is used for RDP, which is a protocol that allows remote desktop connections to a server. These ports should be allowed for a secure web server that can be administered via RDP.

• Question 283:

  A technician is setting up a small office that consists of five Windows 10 computers. The technician has been asked to use a simple IP configuration without manually adding any IP addresses. Which of the following will the technician MOST likely use for the IP address assignment?

  A. Static
  B. Router-assigned
  C. APIPA
  D. DHCP
  D. DHCP

  ---

  Explanation

  DHCP stands for Dynamic Host Configuration Protocol and it is a network protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. DHCP can help simplify IP configuration without

  manually adding any IP addresses. DHCP works by using a DHCP server that maintains a pool of available IP addresses and leases them to devices that request them. The devices can renew or release their IP addresses as needed.

• Question 284:

  A server administrator is setting up a disk with enforcement policies on how much data each home share can hold. The amount of data that is redundant on the server must also be minimized. Which of the following should the administrator perform on the server? (Select two).

  A. Partitioning
  B. Deduplication
  C. Disk quotas
  D. Compression
  E. Cloning
  F. Provisioning
  B. Deduplication
  C. Disk quotas

  ---

  Explanation

  Deduplication is a process that eliminates redundant data blocks and reduces the amount of storage space needed. Disk quotas are policies that limit the amount of disk space that each user or group can use on a volume.

• Question 285:

  A server administrator is installing an OS on a new server. Company policy states no one is to log in directly to the server. Which of the following Installation methods is BEST suited to meet the company policy?

  A. GUI
  B. Core
  C. Virtualized
  D. Clone
  B. Core

  ---

  Explanation

  A core installation is a type of installation method that is best suited to meet the company policy that states no one is to log in directly to the server. A core installation is a minimal installation option that is available when deploying some

  editions of Windows Server. A core installation includes most but not all server roles and features, but does not include a graphical user interface (GUI). A core installation can only be managed remotely using command-line tools such as

  PowerShell or Windows Admin Center, or using graphical tools such as Server Manager or Remote Desktop from another computer. This reduces the attack surface, resource consumption, and maintenance requirements of the server. A GUI

  installation is a type of installation method that includes a graphical user interface (GUI) and allows local or remote management using graphical tools or command- line tools. A virtualized installation is a type of installation method that

  involves creating and running one or more virtual machines on a physical host using a hypervisor such as Hyper- V or VMware. A clone installation is a type of installation method that involves creating an exact copy of an existing server's

  configuration and data on another server using tools such as Sysprep or Clonezilla.

• Question 286:

  A systems administrator noticed a new network card is not being recognized by the operating system. Which of the following is most likely the cause?

  A. The network cable is unplugged.
  B. The driver is not loaded.
  C. The IP settings are incorrect.
  D. PXE boot is enabled.
  B. The driver is not loaded.

  ---

  Explanation

  When a newly installed network card is not being recognized by the operating system, the most likely cause is that the necessary driver is not installed or loaded. Device drivers act as intermediaries between the hardware and the operating

  system. Without the correct driver, the OS cannot communicate with or properly use the network card.

  Other Options:

  Option A: The network cable is unplugged: This would prevent network connectivity, but the OS would still recognize the network card itself. Option C: The IP settings are incorrect: Incorrect IP settings can cause network issues but do not

  prevent the OS from recognizing the NIC. Option D: PXE boot is enabled: PXE (Preboot Execution Environment) allows a system to boot from a network rather than a local disk. While PXE may affect booting, it does not directly cause a NIC

  to be unrecognized by the OS. Thus, the most likely cause is that the driver for the network card is not installed or properly loaded.

• Question 287:

  A server technician is installing a new server and configuring the newly installed OS. Which of the following steps should be performed FIRST after booting the OS?

  A. Create a backup.
  B. Address security concerns.
  C. Connect to the network.
  D. Join to the domain.
  B. Address security concerns.

  Explanation

• Question 288:

  Users in an office lost access to a file server following a short power outage. The server administrator noticed the server was powered off. Which of the following should the administrator do to prevent this situation in the future?

  A. Connect the server to a KVM
  B. Use cable management
  C. Connect the server to a redundant network
  D. Connect the server to a UPS
  D. Connect the server to a UPS

  ---

  Explanation

  The administrator should connect the server to a UPS to prevent this situation in the future. A UPS (Uninterruptible Power Supply) is a device that provides backup power to a server or other device in case of a power outage or surge. A UPS typically consists of one or more batteries and an inverter that converts the battery power into AC power that the server can use. A UPS can also protect the server from power fluctuations that can damage its components or cause data corruption. By connecting the server to a UPS, the administrator can ensure that the server will continue to run or shut down gracefully during a power failure.

• Question 289:

  A server administrator is deploying a new server that has two hard drives on which to install the OS. Which of the following RAID configurations should be used to provide redundancy for the OS?

  A. RAID 0
  B. RAID 1
  C. RAID 5
  D. RAID 6
  B. RAID 1

  ---

  Explanation

  RAID 1 (mirroring) is a RAID configuration that should be used to provide redundancy for the OS on a server that has two hard drives on which to install the OS. RAID 1 (mirroring) is a configuration that duplicates data across two or more drives. It provides fault tolerance and improves read performance, but reduces storage capacity by half. If one drive fails in RAID 1, the other drive can continue to operate without data loss or system downtime. RAID 0 (striping) is a configuration that splits data across two or more drives without parity or redundancy. It improves performance but offers no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 5 (striping with parity) is a configuration that stripes data across three or more drives with parity information. It provides fault tolerance and improves performance, but reduces storage capacity by one drive's worth of space. RAID 5 can tolerate one drive failure without data loss, but not two or more. RAID 6 (striping with double parity) is a configuration that stripes data across four or more drives with double parity information. It provides fault tolerance and improves performance, but reduces storage capacity by two drives' worth of space. RAID 6 can tolerate two drive failures without data loss, but not three or more.
