CompTIA Server+ SK0-005 CompTIA Study Notes

Teaming is a technique that can be configured on a server for network redundancy. Teaming involves combining two or more network adapters into a single logical unit that acts as one network interface. This way, if one network adapter fails, another one can take over without disrupting network connectivity. Teaming can also improve network performance by load balancing traffic across multiple network adapters. Clustering is a technique that involves grouping two or more servers together to act as one system for high availability and fault tolerance. Virtualizing is a technique that involves creating multiple virtual machines on a single physical server to optimize resource utilization and flexibility. Cloning is a technique that involves creating an exact copy of a server’s configuration and data for backup or migration purposes. References: https:/

The DR testing scenario that is described as verbally walking through each step of the DR plan in the context of a meeting is tabletop. A tabletop test is a type of disaster recovery (DR) test that involves discussing and reviewing the DR plan with key stakeholders and participants in a simulated scenario. A tabletop test does not involve any actual execution of the DR plan or any disruption of the normal operations. A tabletop test can help identify gaps, issues, or inconsistencies in the DR plan and improve communication and coordination among the DR team members.

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.

The technician should install the heaviest server at the bottom of the rack to load the rack properly. Installing the heaviest server at the bottom of the rack helps to balance the weight distribution and prevent the rack from tipping over or collapsing. Installing the heaviest server at the bottom of the rack also makes it easier to access and service the server without lifting or moving it. Installing the heaviest server at any other position in the rack could create instability and safety hazards.
