ECP-215 ERICSSON CERTIFIED ASSOCIATE - ERICSSON CLOUD PRACTICE EXAM LATEST
**1. What is the primary goal of Ericsson Cloud infrastructure?**
A) To provide only storage solutions
B) To offer a unified, scalable platform for network functions and applications
C) To replace all physical network equipment
D) To focus solely on consumer cloud services
**Answer: B**
**Explanation:** Ericsson Cloud provides a unified, scalable platform based on cloud-
native principles to host network functions (VNFs/CNFs) and applications, enabling agility
and efficiency for communication service providers.
**2. Which hypervisor is commonly associated with Ericsson Cloud solutions?**
A) VMware ESXi
B) Microsoft Hyper-V
C) KVM (Kernel-based Virtual Machine)
D) Xen
**Answer: C**
**Explanation:** Ericsson Cloud infrastructure often utilizes KVM as the hypervisor, as it is
open-source, integrated with Linux, and aligns with Ericsson's focus on OpenStack and
open standards.
**3. What is the role of OpenStack in Ericsson Cloud architecture?**
A) A container orchestration platform
B) A cloud operating system managing compute, storage, and networking resources
,C) A hypervisor management tool
D) A service mesh layer
**Answer: B**
**Explanation:** OpenStack acts as the cloud operating system (IaaS layer) in Ericsson
Cloud, providing APIs to control pools of compute, storage, and networking resources.
**4. In the context of Ericsson Cloud, what does CEE stand for?**
A) Cloud Execution Environment
B) Container Execution Engine
C) Centralized Ericsson Environment
D) Cloud Ericsson Edition
**Answer: A**
**Explanation:** Cloud Execution Environment (CEE) is Ericsson's cloud platform based on
OpenStack and other open-source components, optimized for telecom workloads.
**5. Which component is responsible for automated deployment and lifecycle
management of VNFs in Ericsson Cloud?**
A) OpenStack Nova
B) Ericsson Network Manager (ENM)
C) Ericsson Cloud Manager (ECM)
D) OpenStack Neutron
**Answer: C**
**Explanation:** Ericsson Cloud Manager (ECM) provides orchestration and lifecycle
management (LCM) for virtualized network functions (VNFs) on the CEE platform.
,**6. What is the purpose of SDN (Software-Defined Networking) in Ericsson Cloud?**
A) To virtualize compute resources
B) To decouple the network control plane from the data plane for flexible, programmable
networking
C) To manage storage pools
D) To provide hypervisor capabilities
**Answer: B**
**Explanation:** SDN separates the network's control logic from the underlying routers
and switches, allowing centralized, programmable control of network resources, which is
crucial for dynamic cloud infrastructure.
**7. What does NFV (Network Functions Virtualization) aim to achieve?**
A) Move network functions from proprietary hardware appliances to software running on
standard cloud infrastructure
B) Increase the speed of physical routers
C) Replace all fiber optic cables with wireless links
D) Virtualize end-user devices
**Answer: A**
**Explanation:** NFV decouples network functions (like firewalls, load balancers) from
dedicated hardware, allowing them to run as software (VNFs) on commercial off-the-shelf
(COTS) servers.
**8. Which Ericsson product provides a centralized operation and management solution
for the cloud infrastructure?**
A) Ericsson Radio System
, B) Ericsson Network Manager (ENM)
C) Ericsson Controller
D) Ericsson Cloud Execution Environment
**Answer: B**
**Explanation:** Ericsson Network Manager (ENM) provides centralized FCAPS (Fault,
Configuration, Accounting, Performance, Security) management for the network, including
cloud infrastructure elements.
**9. When deploying workloads on Ericsson Cloud, what is a key characteristic of a "cloud-
native" application?**
A) It is a monolithic application
B) It is built using microservices, packaged in containers, and dynamically orchestrated
C) It requires a dedicated physical server
D) It cannot be scaled horizontally
**Answer: B**
**Explanation:** Cloud-native applications are designed specifically for cloud
environments, using microservices architectures, containerization (e.g., Docker), and
orchestration (e.g., Kubernetes) for resilience and scalability.
**10. What is the primary benefit of using containers over traditional virtual machines?**
A) Containers provide stronger hardware isolation
B) Containers are lighter-weight, leading to faster startup times and higher density
C) Containers require their own full operating system kernel
D) Containers are better for running legacy monolithic applications unchanged
