CompTIA SK0-005 Dumps Questions Answers

If the network cable is functioning but there is no network connectivity, the next step would be to check theIPv4 options. This includes verifying that the server has a correct IP address, subnet mask, and gateway configuration.

IPv4 options (Answer B):Incorrect IP configuration is a common reason for network connectivity issues.

NIC firmware (Option A):Firmware issues are less likely if the NIC is detecting the cable and appears operational.

DHCP options (Option C):DHCP could be checked if automatic IP assignment is being used, but verifying IPv4 options manually is the first step.

Firewall options (Option D):Firewalls can block connectivity but should be checked after confirming IP settings.

DNS settings (Option E):DNS issues usually affect domain name resolution, not basic network connectivity.

The most likely issue that prevents the newly added server from seeing any of the LUNs on the SAN is that a single-mode fiber cable is used in place of multimode. A single-mode fiber cable is a type of optical fiber cable that has a small core diameter and allows only one mode of light to propagate through it. A single-mode fiber cable can transmit data over long distances at high speeds, but it requires more expensive transceivers and connectors than multimode fiber cables. A multimode fiber cable is a type of optical fiber cable that has a larger core diameter and allows multiple modes of light to propagate through it. A multimode fiber cable can transmit data over short distances at lower speeds than single-mode fiber cables, but it is more compatible and cost-effective than single-mode fiber cables. If a single-mode fiber cable is used in place of multimode, it can cause signal loss, attenuation, or mismatch between the devices. References: [CompTIA Server+ Certification Exam Objectives], Domain 3.0: Storage, Objective 3.2: Given a scenario, compare and contrast various storage technologies.
