a network administrator is implementing a ping from one end of the network to the other, records the average round-trip time and archives the results. what is most likely being prepared? logical network diagram change management documentation network performance baseline standard operating procedures
Answers
Network performance baseline will probably be created by the network administrator.
The best performance measurements for your network can be found by measuring it over a specific length of time. By identifying recommended performance requirements, baseline statistics offer a mechanism to verify the current state of your network, assisting administrators in defining the "normal" functioning level of network devices.
Network administrators can forecast demands and improve network performance by using baselines created by real-time analysis of various network variables, such as device utilisation, CPU/memory usage, connection, resource performance, etc. You can spot potential issues and comprehend network vulnerabilities when a device's performance deviates by being aware of its typical performance characteristics.
You can use network baselines as a reference point for troubleshooting and to better comprehend usage patterns and patterns on the network. To assess and support decision-makers on current policies, network compliance, and upcoming network upgrades, Network Baselines offer useful data.

if the following elements were to form an ionic compound, which noble-gas configuration would they most likely attain?
Answers
which configuration will they get?
Ionic compounds are formed by the combination of a metal and a nonmetal.
The metal atom loses electrons to become a cation with a positive charge, and the nonmetal atom gains electrons to become an anion with a negative charge.
The resulting ions are then attracted to each other by electrostatic forces to form an ionic compound.
The noble-gas configuration is a term used in chemistry to describe the outermost electron configuration of an atom. The noble gases are a group of elements in the periodic table that have a stable electron configuration, with a full outermost energy level.
When atoms react to form compounds, they often gain or lose electrons to attain a noble-gas configuration, which is more stable.
