Question 27
For this question, refer to the TerramEarth case study. To speed up data retrieval, more vehicles will be upgraded to cellular connections and be able to transmit data to the ETL process. The current FTP process is error-prone and restarts the data transfer from the start of the file when connections fail, which happens often. You want to improve the reliability of the solution and minimize data transfer time on the cellular connections. What should you do?

Existing Technical Environment JencoMart hosts all of its applications in 4 data centers: 3 in North American and 1 in Europe, most applications are dual-homed. JencoMart understands the dependencies and resource usage metrics of their on-premises architecture. Application Customer loyalty portal LAMP (Linux, Apache, MySQL and PHP) application served from the two JencoMart-owned U.S. data centers. Database * Oracle Database stores user profiles 20 TB Complex table structure Well maintained, clean data Strong backup strategy * PostgreSQL database stores user credentials Single-homed in US West o No redundancy o Backed up every 12 hours 100% uptime service level agreement (SLA) Authenticates all users Compute * 30 machines in US West Coast, each machine has: o Twin, dual core CPUs o 32GB of RAM Twin 250 GB HDD (RAID 1) * 20 machines in US East Coast, each machine has: o Single dual-core CPU o 24 GB of RAM Twin 250 GB HDD (RAID 1) Storage * Access to shared 100 TB SAN in each location * Tape backup every week Business Requirements * Optimize for capacity during peak periods and value during off-peak periods * Guarantee service availably and support * Reduce on-premises footprint and associated financial and environmental impact. * Move to outsourcing model to avoid large upfront costs associated with infrastructure purchase * Expand services into Asia. Technical Requirements * Assess key application for cloud suitability. * Modify application for the cloud. * Move applications to a new infrastructure. * Leverage managed services wherever feasible * Sunset 20% of capacity in existing data centers * Decrease latency in Asia CEO Statement JencoMart will continue to develop personal relationships with our customers as more people access the web. The future of our retail business is in the global market and the connection between online and in-store experiences. As a large global company, we also have a responsibility to the environment through 'green' initiatives and polices. CTO Statement The challenges of operating data centers prevents focus on key technologies critical to our long-term success. Migrating our data services to a public cloud infrastructure will allow us to focus on big data and machine learning to improve our service customers. CFO Statement Since its founding JencoMart has invested heavily in our data services infrastructure. However, because of changing market trends, we need to outsource our infrastructure to ensure our long-term success. This model will allow us to respond to increasing customer demand during peak and reduce costs.

Question 29
A production database virtual machine on Google Compute Engine has an ext4-formatted persistent disk for data files The database is about to run out of storage space How can you remediate the problem with the least amount of downtime?
Correct Answer: A
On Linux instances, connect to your instance and manually resize your partitions and file systems to use the additional disk space that you added. Extend the file system on the disk or the partition to use the added space. If you grew a partition on your disk, specify the partition. If your disk does not have a partition table, specify only the disk ID. sudo resize2fs /dev/[DISK_ID][PARTITION_NUMBER] where [DISK_ID] is the device name and [PARTITION_NUMBER] is the partition number for the device where you are resizing the file system.
