NO.1 After developing prototype applications in the public cloud, developers
determined that they
want softwaredefined network functionality. Which
ability will this requirement provide for the
developers?
A.
Programmatically control physical core network topologies
B. Programmatically
provision physical network segments and services
C. Programmatically migrate
layer-3 access from aggregate to access switches
D. Programmatically
provision an IPsec VPN tunnel between the public and private clouds
Answer:
B
E20-020기출문제
Explanation:
Software-defined networking (SDN) is
an approach to computer networking that allows network
administrators to
manage network services through abstraction of higher-level functionality. This
is
done by decoupling the system that makes decisions about where traffic is
sent (the control plane)
from the underlying systems that forward traffic to
the selected destination (the data plane).

NO.2 What is a
challenge that is unique to hybrid cloud deployments for authentication
and
authorization systems?
A. Maintaining authentication availability
during an inter-cloud link outage
B. Additional requirements for single
sign-on capabilities
C. Additional costs of scaling authentication server
management
D. Maintaining administrative user credential security
Answer:
B

Explanation:
Single
Sign On The advantage of having a single point of control over users' access to
any
organizational assets should be clear. Extending centralized
authentication policy to cloud resources
provides not only continuity of
control but also maximizes user convenience so that the user need
not provide
different credentials based on the location of the resource. This will be
particularly
important as resources migrate to the cloud over time.

An organization wants to deploy cloud applications using block storage. The
architect has
included a hyperscale storage solution in the cloud
design.
Which requirements led to including this solution in the
design?
A. Organization wants to purchase a storage array Organization wants
to keep storage processing
separate from the application processing
B.
Organization wants to purchase a storage array Organization will use a full mesh
topology to
combine storage and application processing
C. Organization
does not want to purchase a storage array Organization wants to use a full
mesh
topology to combine storage and application processing
D.
Organization wants to purchase a storage array Organization will use a
spine/leaf topology to
combine storage and application processing
Answer:
D
E20-020시험후기
Explanation:
When
customers want converged/hyper-converged infrastructure appliances (or rack
scale systems) -
what customers ask for is this: They want a management and
orchestration stack that spans the
domains of compute/storage/virtualization
(in appliances), and this extends to the top-of-rack
network and spine/leaf
network (in rack-scale systems that must scale to and beyond rack
boundaries
operationally). Note: Hyperscale storage is the storage of vast quantities of
information in
media capable of increasing in size rapidly, efficiently, and
indefinitely. In a data center, hyperscale
storage capacity commonly runs
into the
petabytes.
