LEVEL 3 UNIT 4
AIM OF THE UNIT
This unit aims to give learners an understanding of network
management functions and the role and responsibilities
of the network manager. It will also provide the learners
with the opportunity to obtain practical experience in
undertaking the position of network manager as it relates
to fault diagnosis. Networked computer systems are
everywhere nowadays and with the way business is today,
essential all day every day. It is therefore very important that
business networks run as smoothly, effectively and efficiently
as possible with minimum disruption to the businesses, and
are flexible to any changes as the business requirements
change
Learners will develop an understanding of why organisations
need to have a network management policy and the
requirements for developing the policy.
With technologies changing daily learners need to research
emerging technologies and identify how they could impact
on network systems.
Learners will learn how to plan and carry out a variety of
network management activities on a network with the main
focus being on the maintenance of the system. They will be
expected to keep accurate records which help with checking
that work has been carried out and for documenting any
solutions to potential problems.
Learners will develop the skills and knowledge needed
to effectively use the tools and technologies available to
network managers. They will gain an understanding about
the different functions and types of activities that network
managers need to do. They will become familiar with as
many of the specialist tools that are available to aid network
managers, practically if possible, by demonstration or by
research.

Managing Networks Level 3 Unit 4
DELIVERY GUIDANCE
Have a detailed understanding of network management
functions
The learners will need to understand network management
functions considering and investigating planning, designing,
installing, configuration, security, performance variables,
account management, fault management, checking and
reporting. At this point the learners could be made aware of
the network that they will be managing in learning outcome
3 as it would help put the functions into context for them.
This is not essential but would be helpful to the learner and
make the tasks and exercises more “real”. Learners should
research and plan the activities for an identified network,
showing their considerations. It would benefit learners to
work in small groups to share and explore ideas and different
perspectives and then justify their group findings to a
wider group. From this exercise learners should be able to
develop a comprehensive understanding of the network
management functions.
This unit is a mixture of theory and practical therefore the
learners must have experience of handling and using a range
of network devices and tools.
To cover some of the learning outcomes and grading criteria
the learners will need to practically work with a network.
The tutor will need to make sure that they have access to a
networked system that is not connected to other networks
so the learners will be able to use, configure, and maintain
that network without causing concern to the institutional IT
staff.
Delivery of the unit could be enhanced with talks by and
discussion with visiting network managers.
Learners would benefit from the tutor delivering a theoretical
presentation on the subject area with the learners then
researching the topic followed by practical exercises where
appropriate.
Be able to carry out network management activities
This should be a practical exercise with learners carrying out
network management activities. The learners may choose
to work in their original groups to apply the security features
and security policies they recommended incorporating the
knowledge gained from investigations in learning outcome
2. Simulators or multimedia tools can be used to give the
learners experience before they actually handle the real
thing but should not be the only experience that the learners
are given as they will not be able to experience practically
the activities. Learners should be made aware of different
types and style of work logs as per the teaching content,
and the importance of keeping full and accurate records.
The learning outcome and associated assessment criteria
can not be achieved without the learner carrying out the
management of a real network and a range of different
activities should be given to the learners to allow them to
develop a broader scope of experience.
Know about networking management tools and
technologies
The learners will need to research and evaluate a range of
• network operating systems
• networking protocols
• network layout: • cabling topologies
• wireless
• network devices
• networking tools
• emerging technologies.
When researching the tools and technologies, learners could
be split into small groups and allocated specific topics to
research. They could then report back to the larger group on
their findings and then a wider discussion with the group on
all aspects, strengths and weaknesses would reinforce the
learning.
Emerging technologies may also be taught with a mixture of
practical exploration, scenarios and detailed investigations
by the learners. They should consider the advantages and
disadvantages of the developments and may even suggest
further ways in which technology may practically develop.

SUGGESTED ASSESSMENT SCENARIOS AND TASK PLUS GUIDANCE ON
ASSESSING THE SUGGESTED TASKS
To achieve a pass grade, learners must achieve all the pass
criteria listed in the assessment and grading criteria grid.
P5 Learners will need to use suitable software to interrogate
the network, presenting and explaining the results to include
network assets and configuration.
P6 Learners will need to demonstrate their ability to undertake
routine network management tasks.
Assessment Criteria P1, P2, P3, M1
Learners could create a presentation in which they explain
the range of network management tools. They will need to
describe the network technologies and the purpose of the
network tools looking at emerging technologies.
For merit criterion M2 learners will need to provide evidence of
documenting the management tasks they have completed in P6.
For distinction criterion D1 learners are required to analyse the results
of the interrogation in P5 and to explain their findings, including the
identification of problems and faults and the actions taken related
to them.
As this is a level 3 unit, the speaker’s notes will need to be
very detailed and should be submitted as evidence along
with their presentation.
P1 the learners will need to describe the network
technologies considering all aspects identified in the
teaching content.
P2 the learners will need to give an outline of the purpose of
a range networking management tools, screenshots of the
tools in use would enhance the presentation.
P3 Here the learners will need to show some evidence they
have researched at least two emerging technologies (this
could also be recent network technologies) identifying the
technology, an overview of how it works and purpose.
For distinction criterion D2 learners should be provided with a
scenario in which they are required to design a management
security policy. The learner should explain the steps the identified
organisation should take to maintain their security including details
of user access and rights, security audits, firewall, access control list
policies, documentation to be used and policies and procedures.
This could be evidenced as a report or presentation.
For merit criterion M1 the learners will have to review the
technologies discussed in P1 and to compare how the
technologies might affect the different networks locally and
across sites. This should be enhanced with the aid of examples
which the learner has identified during their research, their
sources should be referenced. This could be presented as a report.
Assessment Criterion P4
Here the learner will need to explain the functions of network
management; the learners will include all areas in the teaching
content. This could be presented as a report or leaflet.
Assessment Criteria P5, P6, M2, D1, D2
The learners could use the network they have created to show
they can manage a network. This is a practical assignment and
can be evidenced through observations as well as detailed
reports, or witness statement all of which will need to be
enhanced with photographs or audio/visual recordings.
