You've deployed a microservice called myapp1 to a Google Kubernetes Engine cluster using the YAML file specified below:

You need to refactor this configuration so that the database password is not stored in plain text.
You want to follow Google-recommended practices. What should you do?

• A.Store the database password in a file inside a Kubernetes persistent volume, and use a persistent volume claim to mount the volume to the container.
• B.Store the database password inside the Docker image of the container, not in the YAML file.
• C.Store the database password inside a Secret object.
  Modify the YAML file to populate the DB_PASSWORD environment variable from the Secret.
• D.Store the database password inside a ConfigMap object.
  Modify the YAML file to populate the DB_PASSWORD environment variable from the ConfigMap.

A website keeps a record of user actions using a globally unique identifier (GIUD) retrieved from Amazon Aurora in place of the user name within the audit record. Security protocols state that the GUID content must not leave the company's Amazon VPC.
As the web traffic has increased, the number of web servers and Aurora read replicas has also increased to keep up with the user record reads for the GUID.
What should be done to reduce the number of read replicas required while improving performance?

• A.Keep the user name and GUID in memory on the web server instance so that the association can be remade on demand. Remove the record after 30 minutes.
• B.Deploy a Amazon ElastiCache for Redis server into the infrastructure and store the user name and GUID there. Retrieve GUID from ElastiCache when required.
• C.Encrypt the GUID using Base64 and store it in the user's session cookie. Decrypt the GUID when an audit record is needed.
• D.Change the GUID to an MD5 hash of the user name, so that the value can be calculated on demand without referring to the database.

You are running multiple microservices in a Kubernetes Engine cluster. One microservice is rendering images. The microservice responsible for the image rendering requires a large amount of CPU time compared to the memory it requires. The other microservices are workloads that are optimized for n1-standard machine types. You need to optimize your cluster so that all workloads are using resources as efficiently as possible.
What should you do?

• A.Create a node pool with compute-optimized machine type nodes for the image rendering microservice.
  Use the node pool with general-purpose machine type nodes for the other microservices
• B.Assign the pods of the image rendering microservice a higher pod priority than the older microservices
• C.Use the node pool with general-purpose machine type nodes for lite mage rendering microservice .
  Create a nodepool with compute-optimized machine type nodes for the other microservices
• D.Configure the required amount of CPU and memory in the resource requests specification of the image rendering microservice deployment.
  Keep the resource requests for the other microservices at the default
