Error rate is the number of corrupted bits expressed as a percentage or fraction of the total sent
For your exam you should know below information about Network performance:
Network performance refers to measurement of service quality of a telecommunications product as seen
by the customer.
The following list gives examples of network performance measures for a circuit-switched network and one
type of packet-switched network (ATM):
Circuit-switched networks: In circuit switched networks, network performance is synonymous with the grade
of service. The number of rejected calls is a measure of how well the network is performing under heavy
traffic loads. Other types of performance measures can include noise, echo and so on.
ATM: In an Asynchronous Transfer Mode (ATM) network, performance can be measured by line rate,
quality of service (QoS), data throughput, connect time, stability, technology, modulation technique and
modem enhancements.
There are many different ways to measure the performance of a network, as each network is different in
nature and design. Performance can also be modeled instead of measured; one example of this is using
state transition diagrams to model queuing performance in a circuit-switched network. These diagrams
allow the network planner to analyze how the network will perform in each state, ensuring that the network
will be optimally designed.
The following measures are often considered important:
Bandwidth – Bandwidth is commonly measured in bits/second is the maximum rate that information can be
transferred
Throughput – Throughput is the actual rate that information is transferred
Latency – Latency is the delay between the sender and the receiver decoding it, this is mainly a function of
the signals travel time, and processing time at any nodes the information traverses
Jitter – Jitter is the variation in the time of arrival at the receiver of the information
Error Rate – Error rate is the number of corrupted bits expressed as a percentage or fraction of the total
sen
The following answers are incorrect:
Bandwidth – Bandwidth is commonly measured in bits/second is the maximum rate that information can be
transferred
Throughput – Throughput is the actual rate that information is transferred
Latency – Latency is the delay between the sender and the receiver decoding it, this is mainly a function of
the signals travel time, and processing time at any nodes the information traverses

Section: Protection of Information Assets
Explanation:
Acceptance testing is the final stage before the software is installed and is available for use. The greatest
impact would occur if the software fails at the acceptance testing level, as this could result in delays and
cost overruns. System testing is undertaken by the developer team to determine if the software meets user
requirements per specifications. Integration testing examines the units/modules as one integrated system
and unit testing examines the individual units or components of the software. System, integration and unit
testing are all performed by the developers at various stages of development; the impact of failure is
comparatively less for each than failure at the acceptance testing stage.

Explanation:
AH, ESP and IKE are the three main components of IPSec. A KDC (Key Distribution Center) is a component of Kerberos, not IPSec.

Section: Governance and Management of IT

Explanation/Reference:
Explanation: An integrated test facility creates a factitious entity in the database to process test transactions simultaneously with live input. Its advantage is that periodic testing does not require separate test processes. However, careful planning is necessary, and test data must be isolated from production data.

Explanation:
Threats exploit vulnerabilities to cause loss or damage to the organization and its assets.

Section: Protection of Information Assets
Explanation:
Tunnel mode with IP security provides encryption and authentication of the complete IP package. To accomplish this, the AH and ESP services can be nested. Choices B and C provide authentication and integrity. TCP services do not provide encryption and authentication.

Protecting human resources during a disaster-related event should be addressed first. Having separate BCPs could result in conflicting evacuation plans, thus jeopardizing the safety of staff and clients. Choices B, C and D may be unique to each department and could be addressed separately, but still should be reviewed for possible conflicts and/or the possibility of cost reduction, but only after the issue of human safety has been analyzed.
