ARCHITECTURES AND VIRTUALIZATION EXAM QUESTIONS ANDANSWERS #2
Which two options are indications of a poorly designed network? (Choose two.) - correct
answer The correct answers are "large broadcast domains" and "security
vulnerabilities." Large broadcast domains allow broadcast traffic to spread to many
devices and negatively affect their performance. Broadcast traffic also burdens the
connection links and consumes bandwidth resources. In poorly designed networks, it is
very difficult to identify data flows, therefore the design does not consider their traffic
and processing requirements, resulting in frequent congestions. Poorly designed
networks do not consider security requirements either, rendering a network more
exposed to security threats.
Which three options are common functions of the distribution layer in a three-tier
hierarchical model? (Choose three.) - correct answer The correct answers are
"termination point for vlans," "central point for configuration of acls," and "first point of
routing in the physical network." The access layer provides physical access to network
resources for end devices. The core layer connects LAN resources to outside networks.
Which option describes the topology design in a spine-leaf network? - correct answer
The correct answer is "The design uses a full-mesh of links between the spine and leaf
layer." In a spine-leaf architecture model, every lower-tier switch (leaf layer) is
connected to each of the top-tier switches (spine layer), which creates a full-mesh
topology.
Match the module of the Cisco Enterprise Architecture Model with its corresponding
description. - correct answer The correct answers are: Enterprise Campus is a module
that provides connectivity for enterprise LAN internal users and to specialized service or
data center area; Enterprise Edge is a module that is concerned with connectivity to and
from outside networks; Service Provider Edge is a module that represents WAN and
internet provider functionalities; Enterprise Remote Locations is a module that
encompasses branch offices, teleworkers, and back-up data centers. Enterprise
Architecture identifies modules that represent specific functional units within a large
enterprise network. The modules also correspond to different physical locations within
the network. Each of the modules and their sub-modules follow other architecture
models in their design. For instance, Remote Data Center sub-module of the Enterprise
Remote Locations module, might follow the Spine-Leaf Network Design.
Match the service models with an appropriate description of its characteristics. - correct
answer The correct answers are: paas is a model that provides infrastructural and
software elements that create an environment for the customer to build their own
applications and includes provider's responsibility for scaling the provided resources;
saas is a model that provides ready-to-use applications, which are regularly updated
and patched by the provider; iaas is a model in which changes in resources are a
responsibility of the customer; and Xaas is a cloud offer that can include any computing
service. Iaas clouds include only computing, storage, and network resources and no
