High: Certified A+ Answers to Key Questions!!
John is talking to the CEO. He says, "I really don't understand this cloud thing. Can you tell
me what it is, briefly?" What is the best explanation you can give? correct answers The cloud
is a network of data centers located around the world that is accessed through the internet and
is designed to store and process information.
Jessica is putting together a presentation on digital transformation. What 3 points should she
include to help explain what it is and why it is important? correct answers - Increased demand
(transformative because supply and demand has increased)
- Rising customer demand (increased availability of content and services has served to
heighten demand)
- Increased supply (Companies are moving faster now and have increased supply - companies
must meet the challenge)
Jose's company runs their own data center to securely manage their health industry data. The
company is beginning to expand to other offices in the country and wants to maintain their
current in-house data access. He has been asked to look into the cloud and recommend the
company's next steps. If Jose wanted his company to join the digital transformation era,
which two options should he recommend to be considered? correct answers - Hybrid cloud
(allows for company to keep their data private while taking advantage of the cloud benefits)
- Private cloud (protects their data while increasing access and scalability)
Ann's organization is recovering from an association with a colocation vendor who went
bankrupt and caused numerous service disruptions. She knows leadership is particularly cost
sensitive now, but also wants to ensure the organization's data is secure regardless of what
might happen to a specific company. Which cloud configuration should Ann recommend the
organization? correct answers Multi cloud (avoids vendor lock in which offers lower costs for
specific servers, and offers increased redundancy to prevent data loss)
Jose is working on a paper to persuade his on-premises based company to move the data-
centric business to the cloud. Which two points likely reflect the company's current state of
affairs? correct answers - They don't have enough processing power to make real time
predictions (increased processing power to convert streaming real-time data to predictions)
- They are unable to convert the volume of data received into digital formats (data is most
useful digitized, which is much easier to convert on the cloud)
Fernando is working with a new machine learning model, which he has trained and deployed.
What 3 steps are left for him to take? correct answers - Monitor predictions (monitor them to
ensure they are on track)
- Manage models (if models need to be adjusted, the different versions must be managed)
- Generate predictions (once deployed, you need to generate predictions)
Linda needs to create a custom machine learning model that identifies defectively
manufactured windshield wipers coming off her company's assembly line. She has all the
photographic data she needs, but no experience in either AI or ML. What is the best product
for Lina to use? correct answers AutoML Vision
, Mark's team is in charge of rendering and encoding video footage for their drone
photography app. The footage is uploaded sporadically and must be encoded with a 10-day
time frame. Unfortunately, due to cost overruns in other departments, the team budget has
been cut dramatically. What is the single best option that would allow Mark to accomplish his
job and still stay within budget? correct answers Use preemptible virtual machines
(preemptible VMs - which offer a substantial discount - are perfect for a job that requires
short term processing and which can be interrupted if needed)
Austin's team is architecting a new application that relies on streaming key-value data. Austin
knows the app will have to respond very quickly to be effective. Which of the following is
the optimum Google Cloud service for Austin's need? correct answers Bigtable (NoSQL key
value data store with extremely low latency and fat read/write operations)
Anthony's team is building out a product catalog for the internal sales team that features real-
time collaborative listings; sales people will be encouraged, but not required to add new
entries to each product's record. Which of the following Google Cloud services should
Anthony use to house the database? correct answers Cloud firestore (NoSQL, features built-
in live synchronization for collaborative applications such as this one)
Danny asked Jim which Google Cloud database service would be better for an upcoming
project: Cloud SQL or Cloud Spanner? Which of the 3 questions does Jim need to ask Danny
to differentiate between the two services? correct answers - How much data will be used?
(Cloud SQL can handle up to 30 TB, but Cloud Spanner can handle much more)
- Do you need managed instances of MySQL, PostgreSQL, or SQL Server with the
corresponding support for SQL? (Cloud SQL supports managed instances of MySQL,
PostgreSQL, or SQL Server with easy MySQL code support)
- Is cost an overriding concern? ( Cloud Spanner is much more expensive than Cloud SQL)
Sly has been asked to develop a system that can predict demand based on historical sales data
over the last 30 days. Which one of the following Google Cloud services would be best for
Sly to use? correct answers BigQuery (works well when analyzing time series data)
KJ is working for a startup company that specializes in transcribing Korean videos into
English, Spanish and French. Which of the following processes should Remy recommend his
company adopt? correct answers Transcribe the videos using the Media Translation API (this
extracts the audio from video, translates it and transcribes it)
Annalise has been asked to identify the lowest-cost method to store a collection of PDF
documents that needs to be accessed by the company's auditors once a quarter. What should
Annalise do? correct answers Use Cloud Storage bucket with Coldline Storage class (allows
access once every 90 days at the lowest cost)
Sarah has been asked to setup a database for a new app that displays which cars used which
parking meters over the last 30 days. The data always includes a parking meter number, the
license plate of the car and the date and time that the car started using the meter. Which type
of database should Sarah choose? correct answers A structured database
Javi is an entrepreneur looking to expand his family's hardware business across multiple
states. Although he has some seed money to start, he really has a vision for quickly growing
