Congrats! Did you have any questions where you needed to interpret or troubleshoot Python? I knew Python was on the objectives but was surprised to see the level of detailed knowledge needed.

Like all exams, there are lots of topics so there's no special emphasis on any one topic.

It's like they say: the exam is "a mile wide and an inch deep."

A company is moving to rebuild its primary business application and wants to minimize the cost of ownership and maintenance. The company is looking towards moving its application to the cloud. Security and regulatory restrictions are not important as the application does not handle confidential information.
What cloud option would best suit their needs?
Public
Hybrid
On-Premises
Private

Explanation​

Click to expand...
The best cloud option for this company would be Public Cloud.
With regard to the service ownership and maintenance costs and security/security regulations constraints, the public cloud seems to be the most practical and efficient solution. The use of public cloud services enables organizations to be charged for the amount of services rendered and eliminates headaches of hardware, infrastructure and maintenance management. This is perfect for a ”non-sensitive” type of the application, which does not require any irenic security or compliance standards.

A cloud administrator is creating instances for databases that data scientists will use to manage big data analytics.
What is the best type of optimization the administrator should consider for these instances?
Memory-optimized
Container-optimized
GPU-optimized
vCPU-optimized

Explanation​

Click to expand...
The administrator should consider the Memory-optimized optimization for these instances in most scenarios.
Most data analytics can be considered big data which involves large datasets which may require a lot of memory for effective processing to take place. Memory-optimized instances have a high memory to cpu ratio and are useful in cases such as in-memory databases, data warehousing, large-scale data analytics and other applications which require a lot of memory. This ensures that the database instances are able to cater for the large amounts of available data.

Considering the general steps outlined for deploying a t2.micro instance on AWS, which step would you evaluate as the most critical for ensuring the security of the instance?
Choosing an instance type
Naming the instance
Selecting an operating system
Defining authentication key pairs, network settings, and storage requirements

Explanation​

Click to expand...
Defining authentication key pairs, network settings, and storage requirements.

This step directly impacts the security of the instance by ensuring that proper access controls (such as SSH key pairs for authentication) are in place, network settings (such as security groups and firewalls) are correctly configured to limit access, and storage encryption or access policies are properly set.

Which of the following scenarios best demonstrates the effective use of cloud virtual networks for a growing e-commerce business?
The business avoids using VLANs and relies solely on physical network segmentation to isolate sensitive data.
The business does not implement any firewalls, assuming that the cloud provider's security measures are sufficient.
Incorrect answer:
The business uses a single virtual network for all its operations, including customer-facing applications and internal processes.
The business integrates its cloud-based virtual network with its on-premises network to ensure seamless communication and scalability.

Explanation​

Click to expand...
The business integrates its cloud-based virtual network with its on-premises network to ensure seamless communication and scalability.

The company combines its network operations, using the cloud virtual network and the required building network as one point of sharing and discussing resources while enabling growth.

This means that the company implements the hybrid model which helps the company use resources from the cloud and on-premises while maintaining good security, scalability, and inter-system communications. It further aids the expansion of the business by allowing the use of cloud services freely while still controlling critical information and operations.

Which of the following is an example of a nation-specific compliance requirement?
FedRAMP
Business rules
PCI DSS
HIPAA

Explanation​

Click to expand...
The example of a nation-specific compliance requirement is FedRAMP (Federal Risk and Authorization Management Program).
FedRAMP is a U.S. government-wide program that provides a standardized approach to security assessment, authorization, and continuous monitoring for cloud products and services used by federal agencies in the United States. It is specific to the U.S. federal government.
  • Business rules are organization-specific, not nation-specific.
  • PCI DSS (Payment Card Industry Data Security Standard) is a global standard for payment card data.
  • HIPAA (Health Insurance Portability and Accountability Act) is specific to the healthcare sector in the U.S., but it's not explicitly a nation-wide government compliance like FedRAMP.

A cloud engineer configures virtualized services for a new cloud-based application rollout.
Which resource area does the engineer focus attention on to determine general I/O functionality requirements?
Compute
Data
Network
Virtualization

Explanation​

Click to expand...
The cloud engineer should focus on Data to determine general I/O (Input/Output) functionality requirements.

I/O functionality typically involves reading from and writing to storage systems, so understanding the data storage and retrieval needs (such as throughput, latency, and storage type) is essential for determining I/O performance in a cloud-based application.

Unable to access CertMaster Labs

T
Hello,

I am wondering if anyone is facing the same issue? CertMaster Labs is not accessible. We have tried to access the lab using different accounts using the office internet, and also from the home internet. The link to the instructor guides is working though.
