NEW QUESTION 26
You are migrating to Cloud DNS and want to import your BIND zone file.
Which command should you use?
gcloud dns record-sets import ZONE_FILE --zone MANAGED_ZONE
- A. MANAGED_ZONE
- B. gcloud dns record-sets import ZONE_FILE --delete-all-existing --zone
- C. MANAGED_ZONE
gcloud dns record-sets import ZONE_FILE --zone-file-format --zone MANAGED_ZONE - D. gcloud dns record-sets import ZONE_FILE --replace-origin-ns --zone
Answer: B
Explanation:
Once you have the exported file from your other provider, you can use the gcloud dns record-sets import command to import it into your managed zone.
To import record-sets, you use the dns record-sets import command. The --zone-file-format flag tells importto expect a BIND zone formatted file. If you omit this flag, import expects a YAML-formatted records file.

NEW QUESTION 32
You need to ensure your personal SSH key works on every instance in your project. You want to accomplish this as efficiently as possible.
What should you do?
- A. Use gcloud compute ssh to automatically copy your public ssh key to the instance.
- B. Create a custom Google Compute Engine image with your public ssh key embedded.
- C. Upload your public ssh key to each instance Metadata.
- D. Upload your public ssh key to the project Metadata.
Answer: D
Explanation:
Overview By creating and managing SSH keys, you can let users access a Linux instance through third-party tools. An SSH key consists of the following files: A public SSH key file that is applied to instance-level metadata or project-wide metadata. A private SSH key file that the user stores on their local devices. If a user presents their private SSH key, they can use a third-party tool to connect to any instance that is configured with the matching public SSH key file, even if they aren't a member of your Google Cloud project. Therefore, you can control which instances a user can access by changing the public SSH key metadata for one or more instances. https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys#addkey
NEW QUESTION 33

NEW QUESTION 41
The security team has disabled external SSH access into production virtual machines in GCP.
The operations team needs to remotely manage the VMs and other resources. What can they do?
- A. Grant the operations team access to use Google Cloud Shell.
- B. Have the development team build an API service that allows the operations team to execute specific remote procedure calls to accomplish their tasks.
- C. Develop a new access request process that grants temporary SSH access to cloud VMs when an operations engineer needs to perform a task.
- D. Configure a VPN connection to GCP to allow SSH access to the cloud VMs.
Answer: A
Explanation:
Grant the operations team access to use Google Cloud Shell.
B (Correct Answer) - Grant the operations engineers access to use Google Cloud Shell.
All the engineer asked is remote access the VMs just like using SSH, so if the machines still have an external IP address, the engineers can access them via SSH using Google Cloud Shell.
This is easies effective way to meet the requirements. All other answers are possible options that might require more setup than worthwhile for your needs.

You want to establish a dedicated connection to Google that can access Cloud SQL via a public IP address and that does not require a third-party service provider.
Which connection type should you choose?
- A. Dedicated Interconnect
- B. Partner Interconnect
- C. Carrier Peering
- D. Direct Peering
