SK0-005 Dumps With Exact Questions and Answers

The technician should boot from the media to install the firmware on the server. Firmware is a type of software that controls the low-level functions of hardware devices, such as BIOS (Basic Input/Output System), RAID controllers, network cards, etc. Firmware updates are often provided by hardware manufacturers to fix bugs, improve performance, or add new features to their devices. To install firmware updates on a server, the technician needs to boot from a media device (such as a CD-ROM, DVD-ROM, USB flash drive, etc.) that contains the firmware files and installation program. The technician cannot install firmware updates from within the operating system because firmware updates often require restarting or resetting the hardware devices.

The technician should use port 22 to configure a server that requires secure remote access. Port 22 is the default port for Secure Shell (SSH), which is a protocol that allows secure remote login and command execution over a network connection using a command-line interface (CLI). SSH encrypts both the authentication and data transmission between the client and the server, preventing eavesdropping, tampering, or spoofing. SSH can be used to perform various tasks on a server remotely, such as configuration, administration, maintenance, troubleshooting, etc.

The ping command output shows that the NIC has an IP address of 192.168.1.100 and a default gateway of 192.168.1.1. However, when the technician tries to ping the default gateway, the reply comes from another IP address: 192.168.1.101. This means that there is another device on the network that has the same IP address as the default gateway, and it is responding to the ping request instead of the intended destination.

A duplicate IP address can cause network connectivity problems, such as packet loss, routing errors, or unreachable hosts. To resolve this issue, the technician should either change the IP address of the default gateway or the device that is conflicting with it, or use DHCP to assign IP addresses automatically and avoid conflicts.

The other options are not correct because they do not explain the ping output. An incorrect default gateway would cause no reply or a destination unreachable message, not a reply from a different IP address. A DHCP misconfiguration would cause an invalid or no IP address on the NIC, not a duplicate IP address on the network. An incorrect routing table would cause routing errors or unreachable destinations, not a reply from a different IP address.
