Computer Network Design and Management Quiz

Computer network technology changes at breakneck speed.

The software development cycle more commonly in use today is a one-time one.

Computer networks are constantly increasing in complexity.

Not all analysis and design projects require all three network connectivity maps.

In a wide area connectivity map, a dotted line between two sites indicates the desired path for data (or voice) transmission.

A metropolitan area connectivity map shares some of the characteristics of wide area maps and some of the characteristics of local area maps.

Latency, delivery rate, and failover are usually significant factors that are included at the local area level.

The streamlining and built-in repetition of the application lifecycle, along with the increased collaboration between the teams working on each app, has come to be known as DevOps.

The term “feasible” has several meanings when it's applied to computer-based projects.

When calculating computer system benefits, you do not need to include intangible benefits.

Project management is the application of specific skills, tools, and techniques to manage processes in such a way that the desired outcome is achieved.

A new method, called waterfall, is starting to be employed by organizations, and it takes a linear path to SDLC.

Computer networks are mission-critical systems and designing a new computer network or increasing the capacity of a current system requires careful planning.

Capacity planning is a fairly easy and fast operation.

A local area overview connectivity map can show how individual workstations or groups of workstations are clustered with switches, routers, and server farms.

Computer simulations are easy to create, mainly because it is difficult to make mistakes in the modeling process and easy to discover them.

Compared to simulation, benchmarking is a relatively straightforward technique and can provide useful information when it's used to analyze a network.

Setting up a benchmark test can be quite time-consuming.

Many experts feel analytical modeling is a good way to determine network capacity.

The advantage of analytical modeling is that it is extremely difficult to create inaccurate analytical models and thus generate results that are invalid.

Once a baseline is created, the results can be used to identify network weaknesses and strengths.

Baseline studies are most effective when they are initiated during a time when the network is experiencing severe problems.

A system's time feasibility is the extent to which the system can be installed in a timely fashion that meets organizational needs.

Capacity planning involves trying to determine the amount of workstation memory necessary to support an application or a set of applications.

Load testing places the full force of anticipated demand on a system to determine if it can handle the load.

Regression testing cannot confirm that changes to one system haven't negatively impacted other systems or functionality.

Puppet is a configuration management tool similar to Chef.

Ansible is an open-source and free automation tool.

NetFlow is a proprietary traffic monitoring protocol from Cisco.

With the increasing speed of technological advancement, organizations are finding the ____ method for SDLC can no longer keep up with demand.

____ is a proprietary traffic monitoring protocol from Cisco that tracks all IP traffic crossing any interface where it is enabled.

Change____ consists of carefully defined processes to evaluate the need for a change, the cost of the change, a plan for making the change with minimal disruption, and a backup plan if the change does not work as expected.

One technique used to model a corporation's network environment is to create ____.

Three different modeling techniques can be used: ____ area connectivity maps, metropolitan area connectivity maps, and local area connectivity maps.

In a wide area connectivity map, mobile or wireless sites are indicated by circles containing the letter ____.

In a wide area connectivity map, external sites, such as suppliers or external agents, are denoted by circles containing the letter ____.

Data rate and security are still important parameters at the metropolitan layer, but ____ is probably not as important as it was in the wide area map.

To examine the nodes in a wide area connectivity map in more detail, an analyst can expand each individual site into a ____ area connectivity map.

A ____ map can show how individual workstations or groups of workstations are clustered with switches, routers, hubs, and server farms.

A system’s ____ feasibility is the extent to which the system can be created, given the company's current finances.

When a company is evaluating a project's ____ feasibility, the company must ask: Will the proposed system produce the expected results?

When a company is evaluating a project's ____ feasibility, the company must ask: Can the proposed system be designed, built, tested, and installed in an amount of time that all parties find reasonable and to which they can agree?

____ projection involves predicting one or more network capacities based on the current network parameters and multiplying those capacities by some constant.

A ____ is an isolated environment where you can experiment with changes or potentially dangerous software without exposing sensitive resources to risk of damage.

____ testing confirms that changes to one system haven't negatively impacted other systems or functionality.

____ testers can verify connectivity and test for line faults, such as open circuits, short circuits, reversed circuits, and crossed circuits.

____ testers measure AC and DC volts, resistance, and continuity.

____ testers have a display that graphically shows a network segment and all the devices attached to it.

A(n) ____ can monitor traffic at a specific interface between a server or client and the network.

It is called ___ when a NIC transmits continuously but does not send valid data.

____ is a standard for generating, storing, and processing messages about events on many networked systems.

Most UNIX and Linux desktop operating systems provide a GUI application for easily reviewing and filtering the information in system ____.

The cloud migration strategy ____ can also be called rip and replace.

The cloud migration strategy ____ can also be called rebuild and rearchitect.

_____ refers to the use of software-based solutions to perform a process or procedure with minimal human intervention.

A ____ is a collection of physical or digital documents that outline the precise steps to complete procedures or operations in a specific IT environment.

____ are important information to know for cloud migration because countries and states have different laws for data protection.

____ is an industry standard created by the Internet Engineering Task Force and designed originally to manage Internet components.

The ____ software controls the operations of a managed element and maintains a database of information about all managed elements.

We call ____ when one environment is active while the other environment receives updates, allowing for further testing, or serving as a backup.

The most active portion of the ALM is the ____ phase.

When a(n) ____ or architect is asked to design or update an IT system, they will typically create a set of models for both the existing system (if there is one) and the proposed system.

In order to create a(n) ____ connectivity map, the modeler begins by identifying each site or location in which the company has an office.

If a company desires a metropolitan area network connection between one of its offices and another business, it can use a(n) ____ connectivity map to outline this connection and define the desired network characteristics.

A(n) ____ analysis is a study used to compare current conditions with desired conditions.

If only an overview of a local network is desired, then the analyst can create a(n) ____ connectivity map.

The ____ feasibility of a system is the extent to which the system can be created and implemented using currently existing technology.

To collect baseline information on ____ you create a list of the number and types of system nodes in the network.

Collecting baseline information on ____ involves listing the types of operational protocols used throughout the system.
