What is the difference between an unspecified passive open and a fully specified passive open ?

Unspecified Passive Open:

An unspecified passive open has a server waiting for a connection request from a client.

Fully Specified Passive Open:

A fully specified passive open has the server waiting for a connection from a specific client.
What is a Protocol ?

What is CPE WAN Management Protocol (CWMP) in short?

CPE WAN Management Protocol(CWMP) is a text based protocol used as an application which is installed towards Customer-premises equipment(CPE) side and Auto Configuration Servers(ACS) side for communication over a network.It provides support for by allowing to download files for software upgradation.It helps in maintaining the performance and status monitoring of the system also allows in remote disgognis.
How does CPE WAN Management Protocol (CWMP) manages software environment?

It provides notification to Auto Configuration Servers(ACS) with success or failure message whenever a module is updated, installed and uninstalled.It also provides enabling/disabling the features of applications.
What are the layers of CPE WAN Management Protocol (CWMP)?

The CWMP protocol is a six layer Protocol.

In the Application Layer side, we have

a) CPE/ACS Management Application
b) RPC methods

In the Transport Layer side, we have

What problem of Simple Network Management Protocol (SNMP) is overcome by CPE WAN Management Protocol (CWMP)?

CWMP overcomes the problems found in SNMP such as implementation which varies for each platform, have problems with the network address translation (NAT) and the two ways communication is not the actual two ways communication, CPE is able to send a message as alarm in SNMP.
How the communication between the Customer-premises equipment(CPE) side and Auto Configuration Servers(ACS) happens?

NOTE: This is objective type question, Please click question title for correct answer.
Can you brief about the usage of Customer-premises equipment(CPE) session and Auto Configuration Servers(ACS) session?

CPE initiated sessions will be used for the RPCs that allow a CPE to inform its various conditions to the corresponding ACS.

The ACS initiated sessions mainly helps for the auto configuration of the CPE.
