Which NIC-teaming technology utilizes all available bandwidth?
A server administrator is taking advantage of all the available bandwidth of the four NICs on the server. Which of the following NIC-teaming technologies should the server administrator utilize?

Community Insight
Candidates often confuse the mechanism (Link Aggregation) with the operational benefit/mode (Load Balancing); the key is recognizing that 'taking advantage of all available bandwidth' describes the load balancing function.
The question tests the distinction between fault tolerance and bandwidth utilization in NIC teaming. While Link Aggregation (LACP) is the underlying protocol, CompTIA Server+ SK0-005 specifically identifies Load Balancing as the functional mode that distributes traffic to maximize throughput across multiple interfaces.
Option D (Link Aggregation) is the most common wrong answer because it is technically the method used to combine links; however, exam questions often prioritize the functional outcome (balancing load) over the technical implementation when distinguishing from simple redundancy modes like Failover.

Why the Answer Is Correct
Load balancing is the specific NIC-teaming mode designed to distribute network traffic across multiple physical adapters to increase total throughput. By splitting the load, the server can utilize the aggregate bandwidth of all four NICs, directly addressing the scenario described. This differs from pure failover modes where only one link is active at a time.Why the Other Options Are Wrong
Failover (A) and Fault Tolerance (B) are primarily about high availability; typically, only one NIC handles traffic while others sit idle as backups, meaning they do not utilize all available bandwidth simultaneously. Link Aggregation (D) is the standard protocol (like IEEE 802.3ad/LACP) that enables the teaming, but in the context of SK0-005 terminology, 'Load Balancing' is the preferred term for the behavior of utilizing bandwidth, whereas aggregation is often viewed as the configuration method or synonymous with bonding in Linux contexts.Community Comment Notes
Comment [1] correctly highlights that load balancing distributes traffic to prevent bottlenecks and increase throughput. Comment [3] provides a nuanced view, noting that link aggregation provides load-balancing capabilities, which explains why many users chose D. However, the consensus leans toward C because the question asks what technology the administrator should utilize to achieve the specific goal of bandwidth maximization, which is the definition of load balancing.Official Reference
Exam Strategy
When an option describes a benefit (like increased bandwidth) and another describes a technical standard (like LACP), look for keywords indicating the purpose of the action. If the goal is performance/throughput, choose Load Balancing; if the goal is simply combining links into one logical interface without specifying traffic distribution, consider Link Aggregation.
