Passing the Nokia Scalable IP Networks exam was a rewarding experience for me, thanks to the valuable practice questions provided by Pass4Success. The exam covered topics such as physical infrastructure that provides interconnections between ISPs and physical separation between service provider and customer responsibilities. One question that tested my knowledge was related to the physical separation between service provider and customer responsibilities, where I had to differentiate between edge and core routers in a network architecture.

Free Nokia 4A0-100 Exam Actual Questions

Note: Premium Questions for 4A0-100 were last updated On Feb. 23, 2026 (see below)

Question #1

Which of the following Nokia 7750 SR components is NOT part of the data plane?

Reveal Solution Hide Solution
Correct Answer: D

The Nokia 7750 SR architecture separates its operations into control plane and data plane functions.

The Data Plane includes hardware components responsible for forwarding traffic at line rate. These components include:

MDA (Media Dependent Adapter) -- interfaces with physical media.

IOM (Input/Output Module) -- performs high-speed packet forwarding and processing.

XMA (eXpandable Media Adapter) -- extends port capacity and media support.

The Control Plane includes the CPM (Control Processor Module), which is responsible for running routing protocols, managing configuration, system operations, and other control-related functions. The CPM does not participate in data forwarding and is thus not part of the data plane.


Nokia SRA Study Guide, Chapter: 'System Architecture -- 7750 SR Components'

Nokia IP Networks and Services Fundamentals -- Section: Control and Data Plane Functions in SR Architecture

Question #2

Which compact flash on a control processing module (CPM) of a Nokia 7750 SR stores the runtime software image and the configuration file?

Reveal Solution Hide Solution
Correct Answer: C

Question #3

How many subnets and host addresses are obtained by subnetting network 201.148.26.0/24 using a /26 subnet mask?

Reveal Solution Hide Solution
Correct Answer: C

Nokia IP Fundamentals Guide -- Chapter: ''Subnetting and Address Calculations''

Subnet Math -- RFC 950 principles

Question #4

Which compact flash on a control processing module (CPM) of a Nokia 7750 SR stores the runtime software image and the configuration file?

Reveal Solution Hide Solution
Correct Answer: C

Question #5

Refer to the exhibit.

An Ethernet Local Area Network (LAN) consists of the components shown in the diagram. Assuming there are no VLANs, how many broadcast domains are on this LAN?

Reveal Solution Hide Solution
Correct Answer: A

A broadcast domain is a logical division of a network in which all nodes can reach each other with broadcast frames (Layer 2). Devices within the same broadcast domain receive broadcast packets sent by others.

In the diagram:

Multiple users connect to hubs.

Hubs are Layer 1 devices and do not break broadcast domains. They simply replicate incoming electrical signals to all ports.

Hubs are then connected to switches.

Switches, unless VLANs are configured, forward broadcasts to all ports except the incoming one, effectively keeping all devices in the same broadcast domain.

The two switches are connected together without VLAN segmentation.

Therefore:

The entire LAN depicted is a single Layer 2 broadcast domain.

There are no routers or VLANs to break or separate the domain.

Correct answer: A. 1
