You need to develop procedures to verify resilience of disaster recovery for remote recovery using GCP. Your production environment is hosted on-premises. You need to establish a secure, redundant connection between your on premises network and the GCP network.
What should you do?

• A.Verify that Dedicated Interconnect can replicate files to GCP. Verify that direct peering can establish a secure connection between your networks if Dedicated Interconnect fails.
• B.Verify that Dedicated Interconnect can replicate files to GCP. Verify that Cloud VPN can establish a secure connection between your networks if Dedicated Interconnect fails.
• C.Verify that the Transfer Appliance can replicate files to GCP. Verify that direct peering can establish a secure connection between your networks if the Transfer Appliance fails.
• D.Verify that the Transfer Appliance can replicate files to GCP. Verify that Cloud VPN can establish a secure connection between your networks if the Transfer Appliance fails.

Dress4Win has asked you for advice on how to migrate their on-premises MySQL deployment to the
cloud.
They want to minimize downtime and performance impact to their on-premises solution during the
migration.
Which approach should you recommend?

• A.Create a dump of the on-premises MySQL master server, and then shut it down, upload it to the cloud
  environment, and load into a new MySQL cluster.
• B.Setup a MySQL replica server/slave in the cloud environment, and configure it for asynchronous
  replication from the MySQL master server on-premises until cutover.
• C.Create a new MySQL cluster in the cloud, configure applications to begin writing to both on premises
  and cloud MySQL masters, and destroy the original cluster at cutover.
• D.Create a dump of the MySQL replica server into the cloud environment, load it into: Google Cloud
  Datastore, and configure applications to read/write to Cloud Datastore at cutover.

Company Overview
JencoMart is a global retailer with over 10,000 stores in 16 countries. The stores carry a range of goods,
such as groceries, tires, and jewelry. One of the company's core values is excellent customer service. In
addition, they recently introduced an environmental policy to reduce their carbon output by 50% over the
next 5 years.
Company Background
JencoMart started as a general store in 1931, and has grown into one of the world's leading brands, known
for great value and customer service. Over time, the company transitioned from only physical stores to a
stores and online hybrid model, with 25% of sales online. Currently, JencoMart has little presence in Asia,
but considers that market key for future growth.
Solution Concept
JencoMart wants to migrate several critical applications to the cloud but has not completed a technical
review to determine their suitability for the cloud and the engineering required for migration. They currently
host all of these applications on infrastructure that is at its end of life and is no longer supported.
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.

PostgreSQL database stores user credentials

- Single-homed in US West
- No redundancy
- Backed up every 12 hours
- 100% uptime service level agreement (SLA)
- Authenticates all users
Compute
30 machines in US West Coast, each machine has:

- Twin, dual core CPUs
- 32 GB of RAM
- Twin 250 GB HDD (RAID 1)
20 machines in US East Coast, each machine has:

- Single, dual-core CPU
- 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 availability 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 applications for the cloud

Move applications to a new infrastructure

Leverage managed services wherever feasible

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 policies.
CTO Statement
The challenges of operating data centers prevent 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 to 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 periods and reduce costs.

The application reliability team at your company has added a debug feature to their backend service to send all server events to Google Cloud Storage for eventual analysis. The event records are at least 50 KB and at most 15 MB and are expected to peak at 3,000 events per second. You want to minimize data loss.
Which process should you implement?

• A.* Batch every 10,000 events with a single manifest file for metadata.
  * Compress event files and manifest file into a single archive file.
  * Name files using serverName-EventSequence.
  * Create a new bucket if bucket is older than 1 day and save the single archive file to the new bucket.
  Otherwise, save the single archive file to existing bucket.
• B.* Compress individual files.
  * Name files with serverName-EventSequence.
  * Save files to one bucket
  * Set custom metadata headers for each object after saving.
• C.* Append metadata to file body.
  * Compress individual files.
  * Name files with a random prefix pattern.
  * Save files to one bucket
• D.* Append metadata to file body.
  * Compress individual files.
  * Name files with serverName-Timestamp.
  * Create a new bucket if bucket is older than 1 hour and save individual files to the new bucket.
  Otherwise, save files to existing bucket
