B. CREATE EXTERNAL TABLE IF NOT EXISTSMOVIE( id INT,original_title
STRING,overview
STRING)STORED BY 'oracle.kv.hadoop.hive.table.TableStorageHandler'TBLPROPERTIES
("oracle.kv.kvstore "="
kvstore ","oracle.kv.hosts"="localhost:5001","oracle.kv.hadoop.hosts"="localhost","oracle.kv.tab1eN
ame"="MOVIE");
C. CREATE EXTERNAL TABLE IF NOT EXISTSMOVIE( id INT,original_title
STRING,overview
STRING)STORED BY
'oracle,kv.hadoop.hive.table.TableStorageHandler'TBLPROPERTIES
("oracle.kv.kvstore"="kvstore","oracle.kv.hosts"="localhost:4001","oracle.kv.hadoop.hosts"=
"localhost","oracle.kv.tab1eName"="MOVIE");
D. CREATE EXTERNAL TABLE IF NOT EXISTSMOVIE( id INT,original_title

STRING)STORED BY 'oracle,kv.hadoop.hive.table.TableStorageHandler'TBLPROPERTIES
("oracle.kv.kvstore"="kvstore","oracle.kv.hosts"="localhost:6001","oracle.kv.hadoop.hosts"=
"localhost","oracle.kv.tab1eName"="MOVIE");
Answer: C
Explanation:
The following is the basic syntax of a Hive CREATE TABLE statement for a Hive
external table over an Oracle NoSQL table:
CREATE EXTERNAL TABLE tablename colname coltype[, colname coltype,...]
STORED BY 'oracle.kv.hadoop.hive.table.TableStorageHandler'
TBLPROPERTIES (
"oracle.kv.kvstore" = "database",
"oracle.kv.hosts" = "nosql_node1:port[, nosql_node2:port...]",
"oracle.kv.hadoop.hosts" = "hadoop_node1[,hadoop_node2...]",
"oracle.kv.tableName" = "table_name");
Where oracle.kv.hosts is a comma-delimited list of host names and port numbers
in the
Oracle NoSQL Database cluster. Each string has the format hostname:port.
Enter multiple names to provide redundancy in the event that a host fails.
QUESTION 3 You need to create an architecture for your customer’s Oracle NoSQL KVStore.
The customer needs to store clinical and non-clinical data together but only the
clinical data is mission critical.
How can both types of data exist in the same KVStore?
A. Store the clinical data on the master node and the non-clinical data on the
replica nodes.
B. Store the two types of data in separate partitions on highly available
storage.
C. Store the two types of data in two separate KVStore units and create database
aliases to mimic one KVStore.
D. Store the two types of data with differing consistency policies.
Answer: B
Explanation:
The KVStore is a collection of Storage Nodes which host a set of Replication
Nodes. Data is spread across the Replication Nodes.
Each shard contains one or more partitions. Key-value pairs in the store are
organized according to the key. Keys, in turn,
are assigned to a partition. Once a key is placed in a partition, it cannot be
moved to a different partition. Oracle NoSQL
Database automatically assigns keys evenly across all the available partitions.
Note: At a very high level, a Replication Node can be thought of as a single
database which contains key-value pairs.
Replication Nodes are organized into shards. A shard contains a single
Replication Node which is responsible for
performing database writes, and which copies those writes to the other
Replication Nodes in the shard.
QUESTION 4
Your customer is spending a lot of money on archiving data to comply with
government regulations to retain data for 10 years.
How should you reduce your customer’s archival costs?
A. Denormalize the data.
B. Offload the data into Hadoop.
C. Use Oracle Data Integrator to improve performance.
D. Move the data into the warehousing database.
Answer: B
Explanation:
Extend Information Lifecycle Management to Hadoop
For many years, Oracle Database has provided rich support for Information
Lifecycle Management (ILM). Numerous capabilities are available for data tiering
– or storing data in different media based on access requirements and storage
cost considerations.
These tiers may scale from
1) in-memory for real time data analysis,
2) Database Flash for frequently accessed data,
3) Database Storage and Exadata Cells for queries of operational data and
4) Hadoop for infrequently accessed raw and archive data:
QUESTION 5
Your customer keeps getting an error when writing a key/value pair to a NoSQL
replica.
What is causing the error?
A. The master may be in read-only mode and as result, writes to replicas are not
being allowed.
B. The replica may be out of sync with the master and is not able to maintain
consistency.
C. The writes must be done to the master.
D. The replica is in read-only mode.
E. The data file for the replica is corrupt.
Answer: C
Explanation:
Replication Nodes are organized into shards. A shard contains a single
Replication Node which is responsible for
performing database writes, and which copies those writes to the other
Replication Nodes in the shard. This is called the
master node. All other Replication Nodes in the shard are used to service
read-only operations.
Note: Oracle NoSQL Database provides multi-terabyte distributed key/value pair
storage that offers scalable throughput
and performance. That is, it services network requests to store and retrieve
data which is organized into key-value pairs.
Microsoft designed Windows 10 to pull users into Windows Store, and it might
be working
Windows 10 users are downloading more apps than Windows 8 users did, and that's
exactly what the Store needs to attract better apps.
Windows 10 users may finally be giving the Windows Store the love it needs to
survive—largely due to smart plotting by Microsoft to make it happen.
Microsoft announced in a blog post Thursday evening that Windows 10 users are
downloading apps at a vigorous rate. “The average Windows 10 customer is
downloading six times more apps than the average customer on Windows 8,” said
Microsoft’s Todd Brix, who authored the post.
This is hardly a grassroots movement, though. Microsoft has designed Windows 10
to drive users to the Windows Store. If it is indeed working, then that’s
hopeful news for the future of the lackluster app store.
Why this matters: A critical mass of Windows 10 users, downloading lots of apps,
is exactly what Microsoft needs to solve its chicken-and-egg problem with
Windows Store. The Windows Store needs better apps, and it won’t get better apps
until it gets more users. Windows 10’s design apparently addresses the user
need. Now we wait to see whether app developers will follow the crowd.
How Windows 10 lures users to Windows Store Microsoft’s Brix stated clearly that Windows 10 lay at the heart of
Microsoft’s campaign to promote the Windows Store. “We have taken steps to
change the way people discover and experience apps in Windows 10,” he explained.
Brix added that the user-hooking techniques are broadly deployed, incorporating
“features both inside and outside of the Store that are fast becoming part of
people’s daily lives.”
Brix went on to describe how Microsoft designed Windows 10 to drive those users
to the Store. “For example, Cortana provides app recommendations based on the
customer’s personal interests. In addition, the Start menu, Microsoft Edge and
the Notification Center will also suggest apps that customers might enjoy.”
(Of course, if you’ve adjusted your Windows 10 privacy settings to fend off the
attentions of these services, you might not get any app suggestions.)
Now all those users need are more and better apps. Microsoft’s working on that,
too: The blog post describes a host of new features designed to make it easier
for users to find and buy apps on the store, and for developers to port existing
apps to the Windows 10 platform.
The big question rises how to become the Microsoft certified , All Microsoft
certifications are acquired by simply taking a series of exams. If you can
self-study for said exams, and then pass them, then you can acquire the
certification for the mere cost of the exam (and maybe whatever self-study
materials you purchase).
You'll also need, at minimum (in addition to the MCTS), the CompTIA A+, Network+
and Security+ certs; as well as the Cisco CCNA cert.
Microsoft Certified Technology Specialist (MCTS) - This is the basic entry point
of Microsoft Certifications. You only need to pass a single certification test
to be considered an MCTS and there are numerous different courses and
certifications that would grant you this after passing one. If you are shooting
for some of the higher certifications that will be discussed below, then you'll
get this on your way there.
Microsoft Certified Professional Developer (MCPD) - This certification was
Microsoft's previous "Developer Certification" meaning that this was the highest
certification that was offered that consisted strictly of development-related
material. Receiving it involved passing four exams within specific areas (based
on the focus of your certification). You can find the complete list of courses
and paths required for the MCPD here.
Microsoft Certified Solutions Developer (MCSD) - This is Microsoft's most recent
"Developer Certification" which will replace the MCPD Certification (which is
being deprecated / retired in July of 2013). The MCSD focuses within three major
areas of very recent Microsoft development technologies and would likely be the
best to persue if you wanted to focus on current and emerging skills that will
be relevant in the coming years. You can find the complete list of courses and
paths required for the MCSD here.
The Microsoft Certifications that you listed are basically all of the major ones
within the realm of development. I'll cover each of the major ones and what they
are :
Most people, however, take some kind of course. Some colleges -- especially
career and some community colleges -- offer such courses (though usually they're
non-credit). Other providers of such courses are private... some of them
Microsoft Certified vendors of one type or another, who offer the courses in
such settings as sitting around a conference table in their offices. Still
others specialize in Microsoft certification training, and so have nice
classrooms set up in their offices.
There are also some online (and other forms of distance learning) courses to
help prepare for the exams.
The cost of taking classes to prepare can vary wildly. Some are actually free
(or very nearly so), while others can cost hundreds of dollars. It all just
depends on the provider.
And here's a Google search of MCTS training resources (which can be mind-numbing
in their sheer numbers and types, so be careful what you choose):
There are some pretty good, yet relatively inexpensive, ways to get vendor
certificate training. Be careful not to sign-up for something expensive and
involved when something cheaper -- like subscribing to an "all the certificates
you care to study for one flat rate" web site -- would, in addition to
purchasing a study guide or two at a bookstore, likely be better.
If you want a career in IT, then you need to have both an accredited degree in
same (preferably a bachelors over an associates), and also a variety of IT
certifications. The MCTS is but one that you will need.
You should probably also get the Microsoft MCSE and/or MCSA. The ICS CISSP. And
the ITIL.
There are others, but if you have those, you'll be evidencing a broad range of
IT expertise that will be useful, generally. Then, in addition, if the
particular IT job in which you end-up requires additional specialist
certification, then you can get that, too (hopefully at the expense of your
employer who requires it of you).
Then, whenever (if ever) you're interested in a masters in IT, here's something
really cool of which you should be aware...
There's a big (and fully-accredited, fully-legitimate) university in Australia
which has partnered with Microsoft and several other vendors to structure
distance learning degrees which include various certifications; and in which
degrees, considerable amounts of credit may be earned simply by acquiring said
certifications. It's WAY cool.
One can, for example, get up to half of the credit toward a Masters degree in
information technology by simply getting an MCSE (though the exams which make it
up must be certain ones which correspond with the university's courses). I've
always said that if one were going to get an MCSE, first consult the web site of
this university and make sure that one takes the specific MCSE exams that this
school requires so that if ever one later decided to enter said school's masters
program, one will have already earned up to half its degree's credits by simply
having the MCSE under his/her belt. Is that cool, or what?
I wouldn't rely on them over experience (which is far and away the most valuable
asset out there) but they are worth pursuing especially if you don't feel like
you have enough experience and need to demonstrate that you have the necessary
skills to land a position as a developer.
If you are going to pursue a certification, I would recommend going after the
MCSD (Web Applications Track) as it is a very recent certification that focuses
on several emerging technologies that will still be very relevant (if not
more-so) in the coming years. You'll pick up the MCTS along the way and then
you'll have both of those under your belt. MCPD would be very difficult to
achieve based on the short time constraints (passing four quite difficult tests
within just a few months is feasible, but I don't believe that it is worth it
since it will be "retired" soon after).
No job experience at all is necessary for any of the Microsoft Certifications,
you can take them at any time as long as you feel confident enough with the
materials of the specific exam you should be fine. The tests are quite difficult
by most standards and typically cover large amounts of material, but with what
it sounds like a good bit of time to study and prepare you should be fine.
Certifications, in addition to degrees, are so important in the IT field, now,
that one may almost no longer get a job in that field without both. The
certifications, though, are so important that one who has a little IT experience
can get a pretty good job even without a degree as long as he has all the right
certs. But don't do that. Definitely get the degree... and not merely an
associates. Get the bachelors in IT; and make sure it's from a "regionally"
accredited school.
Then get the certs I mentioned (being mindful, if you think you'll ever get an
IT masters, to take the specific exams that that Strut masters program requires
so that you'll have already earned up to half the credit just from the certs).
If you already have two years of experience in working in the .NET environment,
a certification isn't going to guarantee that you will get employed, a salary
increase or any other bonuses for achieving the honor. However, it can help
supplement your resume by indicating that you are familiar with specific
technologies enough to apply them in real-world applications to solve problems.

IT’s work can be hidden away and therefore ignored. But it can pay to put a
spotlight on it.
Appreciating IT workers
We all like to know that our efforts are appreciated. For people working in IT,
recognition is too often neglected, simply because so much of what IT workers do
is behind the scenes and goes unnoticed by the majority of employees.
Click through to see five things that Paul Ingevaldson, author of The 9 ½
Secrets of a Great IT Organization, did when he was the CIO at Ace Hardware that
cost little to nothing and that you can implement today.
Two-level reviews My practice was to conduct a follow-up review for everyone in my
organization after their review by their direct supervisor. If you’re worried
that this could take a lot of your time, you’re right. But it’s worth it. The
payoff is that you learn more about employees who don’t report directly to you,
and if you focus on their future in the follow-up review as I did, they feel
more engaged. Be aware, though, that the feeling of engagement will dissipate
if, after ask your employees about their goals and the skills they want to
acquire, you then do nothing to help.
Birthday greetings Is it really worth your time to keep track of all your employees’ birthdays
and send them birthday greetings every year? It was for me. I was always amazed
at the reaction. Invariably, employees would either responded with an emailed
thank-you or conveyed their thanks when they ran into me in the cafeteria line
or hallway. I always sent an email instead of a card, but I liked to make
mention of something that the person was working on and stress its importance to
the department and the company.
Incentives This one costs money as well as time, but coming up with appropriate
incentives for your staff can be very effective. When you publicly give out
rewards for the on-time and on-budget completion of projects, you could find
that other projects experience less spec creep and blown deadlines. Bit by bit,
IT will reap its own rewards, as it gains a reputation of getting the job done
on time.
Awards dinners Done right, an awards dinner can be fun and rewarding for your staff. I did
this every January to recognize the accomplishments of the previous year. If
your budget won’t allow you to host everyone in the IT department, just invite
the senior people in IT, but be sure to include the company officers. Their
presence tells your people that their efforts are appreciated throughout the
company.
As for the awards, I would have my senior managers submit nominations, and then
I made the final decisions. Categories we recognized included “best use of a new
technology to develop a system for the company,” “most important system
implemented during the year,” “the user department that worked best with IT to
develop a new application for the company” and “the department that was the
hardest to deal with.”
Executive helpers I got this idea from an IT magazine. We had a problem getting senior
executives accustomed to using their desktop and mobile computers most
advantageously. Their schedules made offering them classes difficult, but the
executives were also reluctant to display their lack of knowledge in companywide
training classes. The idea I borrowed was to name several IT people who would be
willing to spend one-on-one time with the executives in their offices helping
them to understand the best way to use the technology. The IT staffers had to
promise that they would never use this task as an excuse for not completing
their projects, and the executives had to limit the time to one or two hours a
month.
The result was great. The executives learned a lot about the features of their
systems, and the IT staffers got to meet many of the top executives in our
company.
