Scenario You are a network engineering consultant contracted by a technical school. The school's internal IT team is planning upgrades and large-scale changes, and they have tasked you with analyzing the school's network at the physical level. You must complete a technical diagram based upon the physical components of the network. The diagram must conform to the Open Systems Interconnection (OSI) reference model developed by The International Organization for Standardization (ISO). The OSI reference model is a functional description of the way network appliances, software, and protocols interact with one another at several conceptual levels. You need to consider the following information when completing a technical diagram for the school: - The school staff uses a web conferencing application that establishes authenticated dialogue sessions for stream synchronization and flow control using remote procedure call (RPC) protocol. - The school uses firewall software embedded in the WAN-facing router. To return this interactive to its initial state, click Reset. 1A: Compare and Contrast OSI Model Layers Performance-based Question Instructions Based on the scenario, use the dropdown selectors to select the appropriate protocols, technologies, devices, or layers, then use the checkboxes to select the Layer 7 protocols. For Layers 1 and 2, answers can be in any order. At which layer does the web conferencing session management occur? At which layer does syntax translation such as from Unicode to ASCII occur? Which of the following protocols occur at the application layer (Layer 7)? SMTPSMBDNSSCPRDPTCP/IP.
