Cisco Supporting Cisco Devices for Field Technicians 800-150 FLDTEC Exam Questions

Answer : B

The highlighted component on the Cisco I/O module is the chassis connections LED, which indicates the status of connectivity between the I/O module and the chassis.

In the exhibit, the orange arrow points to a small rectangular LED indicator located to the left side of the I/O module (Cisco UCS-IOM-2304). This specific LED is not aligned with the ports, fans, or screws, which helps identify it correctly.

Chassis connections LED (B) is responsible for indicating the status of uplink/downlink communication between the I/O module and the chassis.

Green usually indicates a healthy link.

Amber or off may indicate a problem or no connection.

Why the other answers are incorrect:

A . Captive screw These are at the far corners, not where the arrow points.

C . Fan module LED This IOM doesn't have user-visible fan LEDs at the front face.

D . Fixed port These are the large rectangular SFP ports clearly visible in the middle, not near the arrow.

This identification is important when troubleshooting chassis-to-IOM connectivity or verifying module status LEDs during field maintenance.

Answer : A

When diagnosing network connectivity issues between a Windows PC and a Cisco device, the combination of ipconfig /all and ping commands provides comprehensive information:

ipconfig /all: Displays detailed IP configuration information, including IP addresses, subnet masks, default gateways, DNS servers, and MAC addresses for all network adapters. This information is crucial for verifying correct network settings.

ping: Tests the reachability of a host on an IP network and measures the round-trip time for messages sent from the originating host to a destination computer. It's a fundamental tool for checking connectivity between devices.

While other commands like netstat, tracert, nslookup, arp -a, and route print provide valuable information, ipconfig /all and ping are typically the first and most informative commands used in initial troubleshooting steps.

Answer : C

The main advantage of Cisco Intersight is its cloud-based architecture, which allows IT administrators to manage infrastructure from any location without needing to install or maintain traditional on-premises management tools.

This provides:

Centralized visibility and control over UCS servers and HyperFlex infrastructure

Remote firmware upgrades and configuration

Policy-driven automation

Unlike on-premises tools, Intersight eliminates the overhead of maintaining dedicated infrastructure for management.

Answer : B

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.

Answer : D

When addressing call quality issues between IP phones, the Real-time Transport Protocol (RTP) is the primary protocol to analyze. RTP is responsible for the actual transmission of voice data during a call, and its performance directly impacts call quality.

Key factors affecting RTP and, consequently, call quality include:

Packet Loss: Missing packets can lead to audio gaps.

Jitter: Variations in packet arrival times can cause choppy audio.

Latency: Delays in packet delivery can result in noticeable lag.

Analyzing RTP streams allows technicians to identify these issues and implement appropriate Quality of Service (QoS) measures to mitigate them.

In contrast:

SIP (Session Initiation Protocol): Handles call setup, modification, and teardown but not the media stream.

SCCP (Skinny Client Control Protocol): A Cisco proprietary protocol for signaling, not media transport.

Answer : A, E

During the password recovery process on Cisco devices, ROMMON (ROM Monitor) mode is utilized to perform specific actions that facilitate the recovery. Two critical actions typically performed in ROMMON mode are:

Change the Configuration Register: The configuration register is modified to instruct the device to ignore the startup configuration during the next boot. This is commonly achieved by setting the configuration register to 0x2142. This action prevents the device from loading the saved configuration, allowing access without requiring the existing passwords.

Reboot the Device: After changing the configuration register, the device is rebooted to apply the new settings. This reboot enables the device to bypass the startup configuration, facilitating the password recovery process.

These steps are essential in the password recovery procedure, allowing administrators to regain access to the device without erasing the existing configuration.

Answer : C

In a Cisco Nexus switch with dual power supplies, the recommended method is to connect each power supply to a separate power source (Option C). This ensures power redundancy and fault tolerance.

If one power source fails (e.g., due to a power outage or circuit failure), the switch can continue operating uninterrupted using the second power source. Connecting both to a single source (Option D) defeats the purpose of redundancy.
