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

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 : A, D

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.

Answer : C, D

On Cisco Catalyst 8000 Series Edge platforms, removing the chassis cover provides access to internal components such as DIMMs (Dual In-line Memory Modules) and SSDs (Solid-State Drives). These components are located internally and require the removal of the chassis cover for maintenance or replacement.

DIMMs are used for system memory and are essential for the router's operation.

SSDs provide storage for system software and configurations.

Other components like Network Interface Modules (NIMs) and transceivers are typically accessible externally and do not require chassis cover removal.

Answer : C

In a local area network (LAN), the primary function of a switch is to operate at Layer 2 (Data Link Layer) of the OSI model. Switches use MAC addresses to forward frames to the appropriate destination ports. This targeted forwarding mechanism divides the network into separate collision domains for each switch port. By isolating collision domains, switches significantly reduce the chance of collisions, enhancing the performance and efficiency of the network.

Unlike hubs, which forward all traffic to all ports (thus creating a single collision domain), switches intelligently forward only the necessary traffic to the correct port. This capability allows multiple simultaneous conversations on different switch ports without interference.

Routers, which operate at Layer 3 (Network Layer), are used to route packets between different networks, not within the same LAN. Wireless connectivity is provided by wireless access points (WAPs), not switches. Encryption is typically handled by security protocols or devices such as firewalls and not by switches directly.

Answer : B

Cisco Nexus switches are specifically designed for deployment in data centers, where they provide high-performance, low-latency switching to support modern workloads, virtualization, and cloud computing environments.

Nexus switches operate using NX-OS, a purpose-built operating system optimized for data center needs. These switches support technologies like virtual port channels (vPC), FabricPath, and Application Centric Infrastructure (ACI), which are essential for scalable and highly available data center networks.

They are not typically used in branch offices, as wireless access points, or as edge routers.

Answer : A

A speed mismatch occurs when two connected Ethernet devices are configured to operate at different speeds. In scenario A, one device is manually set to 1 Gbps, while the other is set to 100 Mbps. Since both ends are hard-coded to different speeds, they cannot successfully negotiate a common speed, leading to a mismatch and resulting in a failed or unstable link.

In contrast, scenario B, where both ends are manually set to the same speed, ensures compatibility and stable communication. Scenario C can lead to a duplex mismatch rather than a speed mismatch; the auto-negotiating end may default to half-duplex if it cannot determine the duplex setting of the manually configured end. Scenario D is less common; if auto-negotiation fails, devices may revert to their lowest common speed, but this typically results in reduced performance rather than a complete mismatch.

Answer : A

The primary reason for placing heavier equipment, such as UPS units or core switches, at the bottom of a rack is to maintain stability. A lower center of gravity reduces the risk of tipping, especially when the rack is not yet bolted or braced.

This is a standard safety precaution in network hardware installation and is particularly important when racks are being serviced or relocated.

The primary reason for placing heavier devices toward the bottom of the rack is to maintain rack stability. This helps ensure the rack remains balanced and prevents tipping, especially when multiple devices are installed.
