ETCP OSS and Network Management 2 — Questions and Answers
Question 1: What protocol does Ericsson ENM use to communicate with YANG-based network elements for configuration?
- SNMP v2c
- NETCONF (Correct answer)
- TFTP
- HTTP/1.1
Correct answer: NETCONF
NETCONF (Network Configuration Protocol) combined with YANG data models is the modern standard for programmatic NE configuration used in ENM.
Question 2: What is Ericsson's AMOS (Advanced MOS) used for in network management?
- Automating customer onboarding
- Providing a command-line scripting interface to manage Ericsson nodes directly (Correct answer)
- Generating capacity planning reports
- Managing DNS zones for operator domains
Correct answer: Providing a command-line scripting interface to manage Ericsson nodes directly
AMOS is Ericsson's proprietary MML-based CLI used to perform operations, maintenance, and configuration tasks directly on Ericsson network nodes.
Question 3: In Ericsson's OSS, what does a 'Software Upgrade Package (SWP)' contain?
- A billing configuration update
- The software load and metadata needed to upgrade a network element to a new release (Correct answer)
- A network topology export
- Customer SLA policy templates
Correct answer: The software load and metadata needed to upgrade a network element to a new release
A Software Upgrade Package contains the new software images, compatibility matrices, and upgrade procedures required to move a NE to a new software version.
Question 4: Which standard does Ericsson ENM use to export performance data for integration with third-party analytics tools?
- 3GPP 32-series (NE PM file formats) (Correct answer)
- ITU-T G.711
- IEEE 802.1Q
- ETSI NFV MANO
Correct answer: 3GPP 32-series (NE PM file formats)
ENM exports performance counter data in 3GPP 32-series XML file formats, enabling interoperability with third-party analytics and BI platforms.
Question 5: What does Ericsson's 'Automatic Neighbor Relation (ANR)' feature in OSS/ENM do?
- Automatically adjusts transmit power based on load
- Discovers and configures neighbor relationships between base stations without manual intervention (Correct answer)
- Provisions subscriber roaming agreements
- Synchronizes clocks across all NEs
Correct answer: Discovers and configures neighbor relationships between base stations without manual intervention
ANR automates the detection of new neighbor cells and the addition or removal of neighbor relations in the RAN, reducing manual OSS configuration effort.
Question 6: What is the role of Ericsson's Service Assurance in an OSS context?
- Managing physical fiber cable runs
- Correlating network faults and performance degradations to their impact on end-to-end services and SLAs (Correct answer)
- Issuing subscriber invoices
- Allocating IP address blocks
Correct answer: Correlating network faults and performance degradations to their impact on end-to-end services and SLAs
Service Assurance translates raw network alarms and performance data into service-level impact views, helping operators prioritize issues based on customer SLA impact.
