Lambda expressions in Java can generate additional objects, known as "captured variables" or "closure instances." These objects may lead to more frequent Garbage Collection, as they are subject to memory management. However, Java's Garbage Collection system is designed to efficiently handle short-lived objects, so the impact is often minimal. Understanding this impact is essential for optimizing memory usage in applications that heavily use Lambdas.

You can use as many else if blocks as needed after an if block. The else if statement allows you to add additional conditions to check when the initial if condition is false. This flexibility enables you to handle various cases in your code, making it more versatile.

The encapsulation of various network layer protocols within IP is a fundamental feature of GRE tunnels.

Twisted pair cabling, especially Cat6 or Cat6a, is recommended for a network that requires a bandwidth of up to 10 Gbps over a distance of 100 meters.

Route summarization reduces the size of the routing table by aggregating multiple routes into a single summary route, which helps in efficient routing table management.

The use of configuration management tools can significantly reduce manual intervention and human errors in automated network deployment and testing.

In VLSM, the subnet size is determined based on the specific requirements of each network segment, allowing for flexibility in addressing.

In IPSec, the IKE protocol negotiates and establishes security associations (SAs) between devices, ensuring secure communication.

Low Latency Queuing is a QoS technique that prioritizes packets based on their sensitivity to delay.

Modern routers employ dynamic routing protocols, enhancing network management and adaptability compared to traditional routers.
