One of the features that can be configured to ensure that GRE overhead does not affect payload is A. jumbo frames. Jumbo frames are Ethernet frames that have a payload size larger than 1500 bytes, which is the standard maximum transmission unit (MTU) for Ethernet. By using jumbo frames, more data can be sent in each packet, reducing the overhead ratio and improving efficiency.

Auto medium-dependent interface (MDI), interface crossover, and collision detection are features related to Ethernet physical layer connectivity, but they do not affect GRE overhead or payload.

An access control vestibule is a physical security mechanism that consists of a small room or chamber with two doors, one leading to the outside and one leading to the secure site. The doors are controlled by an electronic system that verifies the identity and authorization of the person entering before allowing access to the next door. A landing page is a web page that appears when a user clicks on a link or advertisement. A smart locker is a physical security mechanism that allows users to store and retrieve items using a code or biometric authentication. A firewall is a network security device that monitors and filters incoming and outgoing traffic based on predefined rules. References: [CompTIA Network+ Certification Exam Objectives], Domain 4.0 Network Operations, Objective 4.1: Explain the importance of documentation and diagrams, Subobjective: Physical security devices (locks, cameras, etc.)

show interface is a command-line tool that displays information about the status, configuration, and statistics of an interface on a network device. A technician can use show interface to determine where the incident is occurring in a network by checking the uplink status, speed, duplex mode, errors, collisions, and other parameters of each interface.

A VLAN mismatch is the most likely reason why an IP phone does not receive the necessary DHCP options for registration. A VLAN mismatch occurs when a device is connected to a switch port that belongs to a different VLAN than the device’s intended VLAN. This can cause communication problems or prevent access to network resources. For example, if an IP phone is connected to a switch port that belongs to the data VLAN instead of the voice VLAN, it may not receive the DHCP options that contain information such as the TFTP server address, the NTP server address, or the default gateway address for the voice VLAN. These DHCP options are essential for the IP phone to register with the VoIP system and function properly.
