-B is correct The security administrator should use the round-robin algorithm to split the number of connections on each server in half. Round-robin is a load-balancing algorithm that evenly distributes incoming network traffic across multiple servers or resources. With this algorithm, the first request is sent to the first server, the second request is sent to the second server, and so on in a rotating manner. This ensures that each server receives an equal share of the workload. Weighted response is a load-balancing algorithm that takes into account the response time of each server and directs traffic to the server with the fastest response time. Least connection is a load-balancing algorithm that directs traffic to the server with the fewest active connections. Weighted least connection is a load-balancing algorithm that combines the weighted response and least connection algorithms to direct traffic to the server with the fewest active connections and the fastest response time

Selected Answer: B
The round-robin algorithm equally distributes connections among a pool of servers, in a circular manner, providing a simple load-balancing solution. In this case, the administrator wants to split the connections between the two web servers evenly, so the round-robin algorithm would be the best fit.

I am inclined to go with B, round-robin. Least Connection takes into consideration the length of the connections and assigns the servers accordingly. Hypothetically, one server could use all of its resources on several lengthy connections, while the other server has a constant flow of connections and disconnections. Although least connection would facilitate high availability in this scenario (and be a better choice), the number of connections would not necessarily be halved, thereby not meeting the question's criteria. Round robin would not guarantee high availability, however it would half the number of connections, thereby meeting the conditions outlined within the question.

I believe the answer is B. Round Robin. If you research load balancing diagrams, you’ll see that requests are evenly distributed to the servers. And, this question doesn’t mention anything about serve storage sizes.

Round Robin DNS is the poor man load balancer and more useful for internet base LB. F5 LTM is perfect for this. I believe F5 just calls it least connection/session. Can not be Round Robin.

There seems to be a massive misunderstanding about Round Robin, I had that understanding too but then I bout the book. Round-robin: Sends requests to servers by working through a list, with each server receiving traffic in turn. It doesn’t spread them "equally" or "split them in half". The only thing its keeping track of is which server's turn is it now. all types of Weighted load-balancing depend on a predetermined weight value (determined by the admin/sec admin) However, the only possible and logical answer here is C

For clarity, Round Robin loadbalancing IS a thing but it is not specifically mentioned in the exam objectives and therefore should NOT be fair game on the exam.

Least connection will load balance better, because it tracks the current sessions on each server and will assign next connection to the least loaded server. However, ti does not split connections in half because some connections could last more than others. Round robin will do the requested job.

n computer operations, round robin is used in a scheduling algorithm that distributes work evenly among all available resources. This ensures that no single resource is overworked, which can lead to errors and other issues down the line.

No Corp does this. Please google what a F5 Load Balancer does. Round Robin is dead wrong as DNS round robin will never give 50-50 and you be lucky with a 40-60 balance.

Selected Answer: C
I'll go with Least connection. Let's say the S1 has N snd S2 has 0 connections, then all will be assigned to S2. When both have N, the next connection will be assigned randomly so one of them has N+1. The next one will be assigned to the opposite. The same applies to releasing connections. When using the round-robin algorithm, connections on one server may be released faster than on the other, which, when connections are assigned alternately, may result in their uneven distribution. Please correct me, need to pass that in 3 days :c

Least connection is a load-balancing algorithm that directs traffic to the server with the fewest active connections at the time. This would not necessarily split the number of connections on each server in half.

The algorithm that the administrator should use to split the number of connections on each server in half is "Round-robin". This algorithm distributes incoming traffic evenly across all available servers in a circular manner, ensuring that each server receives an equal number of connections. This will help to balance the load between the two servers and prevent resource exhaustion on either server.
