Monitors Network Traffic

Bash is a scripting language that is commonly used in Linux systems to automate tasks and manipulate text.
Bash scripts can run commands, variables, functions, loops, and conditional statements. PowerShell is a scripting language that is mainly used in Windows systems, while batch command files are simple text files that contain a series of commands to be executed by the command-line interpreter. Visual Basic is a programming language that is used to create applications, not scripts.

The first thing the administrator should check is whether the server is in the collection that was scheduled to receive the update through SCCM. A collection is a group of resources, such as computers or users, that can be managed as a single entity by SCCM. If the server is not in the collection, it will not receive the update. The other options are less likely to be the cause of the problem, as they would affect other aspects of the server's functionality besides receiving updates.

* Link Aggregation: Involves combining multiple physical network interfaces into a single logical interface. This creates increased bandwidth, improved fault tolerance, and load balancing, where traffic can be distributed across all links in the group. (CompTIA Server+ Objectives SK0-004: 2.4)
* Why other options are incorrect:
* Most recently used algorithm: A concept used in memory management, not network traffic distribution.
* Active-passive configuration: Used for failover with only one interface active at a time.
* Failover: Ensures service continuity if an interface fails but does not inherently distribute load across multiple links.

NIC stands for network interface card, which is a hardware component that allows a server to connect to a network. Configuring NICs in pairs on a server would provide network redundancy, meaning that if one NIC fails, the other one can take over and maintain network connectivity. The other options are not related to network redundancy.
