Cisco 800-150 Exam Dumps

An on-premises deployment model minimizes dependence on internet connectivity for core collaboration functions. In this model, all critical services, including call control, messaging, and conferencing, are hosted within the organization's local infrastructure. This ensures that internal communication services remain operational even if internet connectivity is lost.

In contrast, cloud-based deployments (Options A and C) and Hosted Collaboration Solutions (Option D) rely on internet connectivity to access services hosted externally, making them more susceptible to internet outages.

The show flash: command is used to display the contents of the device's flash memory, which is where the Cisco IOS image is typically stored. By issuing this command, a technician can verify available space and determine whether there is enough capacity to accommodate a new IOS image before initiating an upgrade or image replacement process.

This command provides a detailed listing of files, their sizes, and the total and available memory space within the flash file system.

show file-system lists all available file systems but doesn't detail their content.

show memory shows runtime memory usage (RAM), not flash memory.

show storage is not a standard IOS command.

===========

In the hierarchical network design model, the access layer is the first layer and serves as the entry point for end-user devices to connect to the network. This layer connects user devices such as PCs, IP phones, wireless access points, printers, and scanners to the network. It facilitates the initial connection between end-user devices and the network infrastructure. The access layer also enforces security policies and provides services such as VLAN membership, port security, and Quality of Service (QoS).

Options A, C, and D refer to functions typically associated with the core or distribution layers, or with WAN connectivity, rather than the access layer.

===========

When connecting two devices of the same type (e.g., two routers, two switches, or two DTEs), a crossover cable is required. This cable swaps the transmit and receive pairs to allow direct communication between devices without the need for an intermediate device like a switch.

Straight-through cables are used to connect different types of devices (e.g., PC to switch).

Rolled cables are used for console access.

USB Type A to B cables are typically used for peripheral device connections, not networking.

Right-To-Use (RTU) licenses are locally managed licenses that allow users to activate specific features on Cisco devices without the need for external tools or connectivity to Cisco's licensing infrastructure. These licenses operate on an honor-based system, where the user agrees to comply with the licensing terms without mandatory enforcement mechanisms.

In contrast:

Hybrid licenses combine aspects of traditional and smart licensing models.

PAK (Product Authorization Key) licenses require registration and activation through Cisco's licensing portal.

Smart licenses necessitate communication with Cisco's Smart Licensing servers for activation and management.
