CompTIA SK0-005 Online Questions & Answers

• Question 121:

  An administrator is troubleshooting connectivity to a remote server. The goal is to remotely connect to the server to make configuration changes. To further troubleshoot, a port scan revealed the ports on the server as follows:

  Port 22: Closed

  Port 23: Open

  Port 990: Closed

  Which of the following next steps should the administrator take? Reboot the workstation and then the server.

  A. Open port 990 and close port 23.
  B. Open port 22 and close port 23.
  C. Open all of the ports listed.
  D. Close all of the ports listed.
  B. Open port 22 and close port 23.

  ---

  Explanation

  Port 22 is used for SSH (Secure Shell), which is a secure and encrypted protocol for remote access to a server. Port 23 is used for Telnet, which is an insecure and unencrypted protocol for remote access. Port 990 is used for FTPS (File Transfer Protocol Secure), which is a secure and encrypted protocol for file transfer. The administrator should open port 22 and close port 23 to enable SSH and disable Telnet, as SSH is more secure and reliable than Telnet. The administrator does not need to open port 990, as FTPS is not required for making configuration changes123.

• Question 122:

  An administrator is setting up a new server and has been asked to install an operating system that does not have a GUI because the server has limited resources. Which of the following installation options should the administrator use?

  A. Bare metal
  B. Headless
  C. Virtualized
  D. Slipstreamed
  B. Headless

  ---

  Explanation

  A headless installation is an installation method that does not require a graphical user interface (GUI) or a monitor, keyboard, and mouse. It can be done remotely through a network connection or a command-line interface. A headless

  installation is suitable for a server that has limited resources and does not need a GUI.

• Question 123:

  Users are able to connect to the wireless network, but they are unable to access the internet. The network administrator verifies connectivity to all network devices, and there are no ISP outages. The server administrator removes the old address leases from the active leases pool, which allows users to access the internet.

  Which of the following is MOST likely causing the internet issue?

  A. The DHCP exclusion needs to be removed.
  B. The DHGP scope is full.
  C. The DHCP scope options are misconfigured.
  D. The DHCP lease times are too short.
  E. The DHCP reservations need to be configured.
  B. The DHGP scope is full.

  ---

  Explanation

  This is most likely a typo.Based on the given information, the most likely cause of the internet issue is that the DHCP scope was full.

  DHCP (Dynamic Host Configuration Protocol) is a network protocol used to automatically assign IP addresses and other network configuration settings to devices on a network. A DHCP scope is a range of IP addresses that are available for

  assignment to devices on the network.

  If the DHCP scope is full, then new devices that try to connect to the network will not be able to get an IP address and other necessary network configuration settings from the DHCP server. In this case, removing old address leases from the

  active leases pool would free up some IP addresses for new devices to use, allowing them to access the internet.

  The other options (A, C, D, and E) could also cause DHCP-related issues, but they are less likely to be the cause of this specific problem based on the information given.

• Question 124:

  An organization is donating its outdated server equipment to a local charity. Which of the following describes what the organization should do BEFORE donating the equipment?

  A. Remove all the data from the server drives using the least destructive method.
  B. Repurpose and recycle any usable server components.
  C. Remove all the components from the server.
  D. Review all company polices.
  D. Review all company polices.

  ---

  Explanation

  Before donating the outdated server equipment to a local charity, the organization should review all company policies regarding data security, asset disposal, and social responsibility. This can help ensure that the donation complies with the legal and ethical standards of the organization and does not pose any risk to its reputation or operations. Verified

• Question 125:

  A technician is investigating a server's configuration to secure it from physical threats. The technician checks the BIOS and sees the following boot order:

  USB Drive CDROM Drive Network Adapter RAID Controller

  Additionally, the server's host OS is stored on mirrored drives.

  Which of the following should the technician do to secure the server?

  A. Disable all except RAID Controller.
  B. Block USB ports on the server.
  C. Set BIOS password.
  D. Move RAID Controller to the top of the list.
  B. Block USB ports on the server.

• Question 126:

  The Chief Information Officer (CIO) of a datacenter is concerned that transmissions from the building can be detected from the outside. Which of the following would resolve this concern? (Choose two.)

  A. RFID
  B. Proximity readers
  C. Signal blocking
  D. Camouflage
  E. Reflective glass
  F. Bollards
  C. Signal blocking
  E. Reflective glass

  ---

  Explanation

  The best solutions to resolve the concern of transmissions from the building being detected from outside are signal blocking and reflective glass. Signal blocking is a method of preventing or interfering with electromagnetic signals from escaping or entering a certain area. Signal blocking can be achieved by using various materials or devices that create physical barriers or generate noise or jamming signals. Signal blocking can protect data transmissions from being intercepted or eavesdropped by unauthorized parties. Reflective glass is a type of glass that has a coating or film that reflects light and heat. Reflective glass can reduce glare and solar radiation, as well as prevent visual observation from outside. Reflective glass can enhance privacy and security for datacenter operations.

• Question 127:

  Which of the following often-overlooked parts of the asset life cycle can cause the greatest number of issues in relation to PII exposure?

  A. Usage
  B. End-of-life
  C. Procurement
  D. Disposal
  D. Disposal

• Question 129:

  A server administrator needs to keep a copy of an important fileshare that can be used to restore the share as quickly as possible. Which of the following is the BEST solution?

  A. Copy the fileshare to an LTO-4 tape drive
  B. Configure a new incremental backup job for the fileshare
  C. Create an additional partition and move a copy of the fileshare
  D. Create a snapshot of the fileshare
  D. Create a snapshot of the fileshare

  ---

  Explanation

  The best solution to keep a copy of an important fileshare that can be used to restore the share as quickly as possible is to create a snapshot of the fileshare. A snapshot is a point-in-time copy of a file system or a volume that captures the state and data of the fileshare at a specific moment. A snapshot can be created instantly and with minimal overhead, as it only stores the changes made to the fileshare after the snapshot was taken. A snapshot can be used to restore the fileshare to its previous state in case of data loss or corruption.

• Question 130:

  Which of the following backup types will MOST likely have a third party hosting the backup data?

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