What are Network Address Translation (NAT) inside global addresses?
Network Address Translation (NAT) inside global addresses are public IP addresses used by the local network to communicate with the Internet. These addresses are assigned by the NAT router to replace the private IP addresses of devices on the local network when they access external networks, ensuring that the local IP addresses remain hidden and providing a level of security and management.
Which topology is considered a best practice when stacking switches?
A ring topology is considered a best practice when stacking switches because it provides redundancy and resilience. In a ring topology, if one switch fails, the data can still travel in the opposite direction to reach its destination, ensuring network continuity and reducing downtime.
Which option is used to configure Network Address Translation (NAT) to provide one-to-one mapping between local and global addresses?
To configure Network Address Translation (NAT) to provide a one-to-one mapping between local and global addresses, you use an Inside Source Static configuration. This type of NAT configuration ensures that a specific local IP address is always translated to the same global IP address, thereby creating a fixed, one-to-one relationship.
What is the valid range assigned to a client during a TCP connection?
During a TCP connection, the valid range assigned to a client is usually from 1024 to 65535, known as ephemeral ports or dynamic ports. The option closest to this range is from 40000 to 65535, making it the correct answer in this context.
Which port and protocol is used by NTP to communicate?
NTP (Network Time Protocol) uses UDP port 123 for both the source and destination to communicate. This is because NTP requires minimal transmission delay and overhead, and UDP is more suitable for such lightweight, time-sensitive operations compared to TCP.
