Cisco Updated 800-150 Exam Questions and Answers by nuala

These components are part of theCisco Collaboration System Architecture (CSA), and are reviewed in theFLDTEC trainingunderCisco Equipment and Collaboration Basics:

Call Control: Managed by services likeCisco Unified Communications Manager (CUCM), it routes and connects calls.

Collaboration Applications: Provide added value services such asvoicemail (Unity),messaging (IM&P), presence, and more.

Edge Devices: IncludeCisco ExpresswayandCUBE(Cisco Unified Border Element), offering secure access and traversal for mobile/remote endpoints.

Conferencing: Powered by platforms likeCisco Meeting ServerorWebex, enabling multi-party conferencing.

Endpoints: Include bothhardware (IP phones, video units)andsoftware (Webex app)that users interact with directly.

When configuring a network port for a newly installed IP phone, two critical parameters to ensure optimal performance are:​

VLAN Assignment:Assigning the correct VLANs is essential for segregating voice and data traffic. Typically, a separate voice VLAN is configured to prioritize voice traffic and enhance security.​

Power over Ethernet (PoE):PoE allows the switch to supply power to the IP phone over the same Ethernet cable used for data transmission. This eliminates the need for separate power supplies and simplifies installation.​

While QoS classification (Option E) is important for prioritizing voice traffic, it is typically configured at a broader network level. Link aggregation (Option B) and Spanning Tree Protocol (Option C) are more relevant to network redundancy and loop prevention, respectively, and are not directly critical for the initial configuration of an IP phone port.​

In theInfrastructure as a Service (IaaS)model, the cloud provider is responsible for managing and maintaining the underlying infrastructure components, including:

Networking: The cloud provider handles all aspects of network configuration, hardware, and virtual networking.

Storage: The cloud provider supplies and manages the physical and virtual storage infrastructure required to support the consumer’s data needs.

The customer is responsible for managing:

Operating Systems

Applications

Data

This model offers flexibility while shifting infrastructure maintenance responsibilities to the service provider.

When configuring a terminal emulator (such as PuTTY, Tera Term, or HyperTerminal) to connect to the console port of a Cisco switch, the standard settings are as follows:​

Speed (baud rate): 9600This is the default transmission speed for Cisco console ports, ensuring compatibility across various devices.​

Data bits: 8This setting specifies that each character transmitted consists of 8 data bits, which is standard for most serial communications.​

Parity: NoneNo parity bit is used, meaning there is no additional error-checking bit appended to each character.​

Stop bits: 1One stop bit indicates the end of a character transmission.​

Flow control: NoneNo flow control is employed, allowing continuous data transmission without hardware or software-based pausing.​

Therefore, optionsC (Speed: 9600)andD (Data bits: 8)are correct. Options A (Stop bits: 2), B (Flow control: Hardware), and E (Parity: Even) deviate from the standard settings and may result in communication issues if configured.​
