$ docker run -d -it ubuntu /bin/bash

To stop a Container.

$ docker stop container_id

To restart a Container.

$ docker restart container_id

To Connect to a running Container.

$ docker attach container_id

To copy a file from a container to the host, you can use the command

$ docker cp containerId:/file/path/within/container /host/path/target

Copying files from host to docker container

$ docker cp foo.txt mycontainer:/foo.txt

$ docker cp mycontainer:/foo.txt foo.txt

Be alerted to key milestones in the learning path, and review how your results will be calculated and distributed. You’ll be required to complete your participant profile, confirm your certificate delivery address, and submit a digital copy of your passport/identity document.



Module 1: An Introduction to Artificial Intelligence


This introductory module guides you through the evolution of key AI technologies and how they have developed to transform industry and business practice. The relationship between AI and collective intelligence, as well as the implications of this partnership for business strategy and society are also introduced. As part of an ongoing project, you’ll begin to consider your own organization in terms of the application of AI technologies.




Module 2: Machine Learning in Business

In this module, you’ll explore the core concepts of machine learning – an AI technology which aims to design, understand, and use computer programs to learn from experience. Discover how machine learning can be successfully integrated into business functions through rich case studies and faculty-led videos that examine the opportunities that this subfield of AI affords. For your ongoing project, you’ll propose ideas for the application of machine learning in a business context of your choice.




Module 3: Natural Language Processing in Business


This module is devoted to natural language processing (NLP), an AI technology developed to intelligently process human language. Through rich case studies and faculty-led videos, which explore functions such as machine translation, summarization, and sentiment analysis, you’ll learn how NLP can be skillfully deployed in a series of business contexts. For the next part of your project, the focus will shift to NLP and its strategic implementation in a business context of your choice.




Module 4: Robotics in Business


This module delves into the key elements of robotics as a transformative AI technology, with a focus on automating processes and tasks. Through rich case studies and facultyled videos that survey robots and autonomous vehicles, you’ll learn how robotics can benefit an organization. You’ll have the opportunity, once more, to submit ideas regarding the potential for robotics to be deployed in a business context of your choice.




Module 5: Artificial Intelligence in Business and Society


In this module, you’ll see examples of other kinds of AI as well as return to collective intelligence and the human-machine relationship. Here you’ll also consider the impact of AI on jobs, and the ethical and social implications of AI integration. You’ll be tasked with anticipating and planning for the risks and considerations that may apply to integrating AI in a business context of your choice.




Module 6: The Future of Artificial Intelligence


This module will allow you to imagine the future of AI and its potential use in your organization. Using what you have learned from the previous modules, you’ll create a business roadmap for the strategic implementation of AI and collective intelligence into an organization of your choice.

Question:

A WebLogic Server instance can have multiple network channel for it.
Each channel for the server must have a unique combination of two element. Identify these two elements.

Response:

	Channel weight
	Tunneling enabled
	Listen address
	Listen port

Score 1 of 1

Question:

You need to monitor the HTTP session count for a running web application.
Identify three ways to perform this monitoring.

Response:

	Use the application’s Monitoring tab in the Administration console .
	Run the jstat tool in your JDK.
	Write and run a custom WLST script.
	Use the Monitoring Dashboard in the Administration console.
	Use the cloud control page in the Administration console.

Score 1 of 1

Question:

As the technical lead for your project, you have been asked to recommend a new solution to handle frequently increasing loads on your applications. The Weblogic 12.1.2 domain currently runs with two clusters of three servers with request being filtered and passed by a proxy server that users the round –robin algorithm. 
However, the load sometimes exceeds the maximum capacity of all these servers combined but your domain lacks in scalability.
What is the best implementation solution?

Response:

	Replace the software load balancer with a hardware load balancer.
	Tune work managers to optimize work.
	Modify the proxy server load balancing algorithm to weight based.
	Configure dynamic clusters and specify the number of server instances you anticipate at needing at peak load.
	Add a third cluster and spread existing server instances across the clusters.

Score 1 of 1

Question:

A WebLogic server domain contains a dynamic cluster called “cluster1”.The cluster “cluster”1 has two dynamic managed servers “server1” and “server2”. There is a need to view the inherited attribute values for “server2”.
How do you view all attributes of “server2”.including those inherited from the server template?

Response:

	Use java weblogic.Deployer.
	You cannot, because attribute values are not inherited.
	Use WLST.
	Use WebLogic Administration console >”server” link.

Score 0 of 1

Question:

In the certification matrix for your version of WebLogic Server , you find the row for your database and its version. In that row, in the “type of database use” column, it says “application data access only”.
Your database cannot be used __________.

Response:

	In a production environment
	By an Enterprise JavaBean
	By a multidata source
	By the administration server
	For internal data storage by WebLogic server

Score 1 of 1

Question:

A global (distributed) transaction involves more than one _______________________.

Response:

	WebLogic Server
	Transactional resource
	Domain
	Cluster
	Continent

Score 1 of 1

Question:

You are in the process of planning a deployment in which a single WebLogic cluster will host a web application. There are several options to consider.
Which is not a valid decision?

Response:

	Replicated or persistent HTTP sessions
	Proxy plug-in or hardware load balancer
	Single or multiple domains
	Unicast or multicast communication
	Configured or dynamic cluster

Score 1 of 1

Question:

A web application is configured for in-memory replication and is deployed to a cluster. This cluster is distributed across two buildings on a university campus. For performance reasons, you requires that session replication occur within the building whenever possible.
How do you implement this requirement?

Response:

	Configure the application’s cookies parameters.
	Disable the dynamic server list in the proxy plug –in.
	Configure each server’s replication group.
	Configure the cluster to use multicast communication.

Score 1 of 1

Question:

A WebLogic server (WLS) domain was recently updated from WLS 10.3.6 to WLS 12.12.
What is the mode of operation of the Node Manager after the update and what is needed to keep the same behavior as in WLS 10.3.6?

Response:

	Node Manager mode of operating and behavior can be selected in reconfiguration Wizard.
	Nothing, Node Manager runs and behaves the same on both WLS versions
	Node manager runs in “per domain” mode and requires manual steps to return to the “per machine” mode, used in WLS10.3.6.
	Node Manager runs in “per machine” mode and nothing is needed to keep the same behavior.

Score 1 of 1

Question:

You use the Java –based Node Manager to start your managed servers. You want Node Manager to:
• Stop servers by using your custom stop script : mystopit.sh
• Restart servers when the hardware cases
• Use SSL communication
• Check server heath once per second
Below are portions of the node manager. properties file. Select the one that configures Node manager as described.

Response:

	StopScriptEnabled=true StopScriptName=mystopic.sh CrashRestartEnabled=true SecureListtenser=true StateCheckinterval=1000
	stopscriptenabled=true Stopscriptname=mystopit.sh crashRecoveryEnabled=true secureListener=SSL statecheckinterval=1000

Question:

You want to configure WebLogic server transactions to be recoverable when a nonclustered managed server crashes, even if that crash is caused by an unrecoverable hardware failure. You want to run the managed server on different hardware, and have it recover the transactions that were in-progress at the time of the crash.
You also want to use the default store for transaction logs.
Which statement is true?

Response:

You configure a data source with a non XA driver because your (non-Oracle) database does not provide XA drivers.
The data source will sometimes participate in global transactions with an EJB, so as you configure the data source you select “Supports Global Transactions” and One-phase commit.
Why is this configuration wrong?

Response:

	"One-Phase Commit" processes this data source last In the global transactions, if the EJB must go last, you cannot use this configuration.
	"One-Phase Commit" only allows this data source to participate in global transaction, so you cannot have a global transaction that includes an EJB.
