CompTIA Updated SK0-005 Exam Questions and Answers by giovanni

If the network cable is functioning but there is no network connectivity, the next step would be to check the IPv4 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.

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. References: [CompTIA Server+ Certification Exam Objectives], Domain 4.0: Networking, Objective 4.1: Given a scenario, configure network settings for servers.

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. References: [CompTIA Server+ Certification Exam Objectives], Domain 2.0: Hardware, Objective 2.4: Given a scenario involving server management issues (e.g., remote access), troubleshoot using appropriate tools.
