Jumbo frames are Ethernet frames with a payload greater than the standard 1,500 bytes. Using jumbo frames reduces the number of frames transmitted over the network, thereby reducing the overhead associated with frame headers and processing. The document explains:

“Jumbo frames are used in storage networks to reduce device overhead by lowering the number of frames required for data transfer, which can increase overall throughput and performance.”

To monitor server availability, SNMP traps are the best choice. SNMP (Simple Network Management Protocol) allows devices to send alerts (traps) when certain conditions are met, such as server downtime or high resource usage.

Breakdown of Options:

A. Packet capture – Capturing packets provides insights into network traffic but does not actively monitor server availability.

B. Data usage reports – These analyze network traffic consumption but do not indicate whether a server is available or not.

C. SNMP traps – Correct answer. SNMP traps notify administrators of server issues in real time.

D. Configuration monitoring – This tracks configuration changes rather than availability.

Shoulder surfing is a social engineering attack where attackers observe someone’s private information by looking over their shoulder or using tools like cameras to capture input.

From Andrew Ramdayal’s guide:

“Shoulder surfing is the act of watching someone enter confidential information, such as PINs or passwords, often using direct line-of-sight or surveillance equipment.”

Port mirroring, also known as SPAN (Switched Port Analyzer), is used to send a copy of network packets seen on one switch port (or an entire VLAN) to another port where the IDS is connected. This allows the IDS to passively inspect network traffic without interfering with the actual traffic flow. Port mirroring is an essential feature for implementing IDS in a network for traffic analysis and security monitoring.References: CompTIA Network+ study materials.
