SIA EXAM QUESTIONS AND 100%
VERIFIED ANSWERS
NIST (The National Institute of Standards and Technology) defines three types
of cloud services including SaaS, PaaS and IaaS - ANSWER All three can be
used in a devops context
In which cloud service model consumers are allowed to have control over
operating systems, storage, and deployed applications? - ANSWER IAAS
DevOps and continuous deployment require the implementation part of service
transition to be highly automated so it can deal with high-frequency transition
and provide better quality control. - ANSWER False, instead of
implementation it is DELIVERY
With the help of DevOps, incidents that are related with the operation of
particular software system are routed to the development team. One example
about how DevOps is changing the traditional operations activities. - ANSWER
True
As Amazon states in its rules for teams, their teams can communicate with all
others through direct linking, direct reads of another team's datastore, or shared-
memory model. - ANSWER False
We should prevent likely changes from rippling through a service by
introducing special modules whose sole purpose is to localize and isolate
changes to the environment, to other services, or to third-party software or
libraries. - ANSWER True
,In order to remove the inter-team coordination, a design decision of system
architecture should be made to allow each component to be allocated to a single
(virtual) machine or container but avoid multiple components to be allocated to
a single (virtual) machine. - ANSWER False
An architect involved in a DevOps project should ensure the following:
(This is a multiple answers question and you must select all that are correct for
full credit.) - ANSWER Every stage of the deployment pipeline has a suite of
automated tests using an appropriate test harness.
Configuration parameters should be separated according to whether they are
going to vary between distinct environments and according to their sensitivity.
The different tools and environments are prepared to make it possible for their
activities to be traceable and reproducible.
Which of the following are possibilities regarding how it is decided which
component is in charge of a new instance of a service provisioning and
deprovisioning? Choose all that apply. - ANSWER It can be the client, or any
component in the client chain, that is supposed to be responsible for instance
(de)provisioning of a service.
An external component monitors the performance of service instances, for
example their CPU load, and (de)provisions an instance when the load reaches a
given threshold.
A service itself can be responsible for the (de)provisioning of additional
instances.
, A good global design decision of architecture for systems must be able not only
to provide the capability to have each component allocated to a single virtual
machine or container but also multiple components allocated to one single
virtual machine. - ANSWER True
Making Ops in other words more responsible for relevant incident handling
with a view to shortening the time between observing an error and repairing that
error is one important category of DevOps practices identified in the textbook. -
ANSWER False, Make DEV more responsible for incident handling
Because Chef is a configuration management tool, it cannot be used to maintain
traceability of errors or keeping track of all changes it applies to a machine. -
ANSWER False
When user issues a command to create a VM, this user must also decide on
which physical machine to create the VM instance. - ANSWER False
A key trend in DevOps is to manage all of the code and parameters for
establishing an environment in exactly the same way you manage your
application code, including proper version control and testing. This is a
"platform-as-code" example. - ANSWER False(infrastructure-as-code)
A feature toggle can be implemented through a loop statement using a global
Boolean variable. - ANSWER False
Which of the following characteristics is defined by NIST of cloud? -
ANSWER Measured service
