NO.65 You have created a firewall with rules that only allow traffic over HTTP, HTTPS, and SSH ports. While testing, you specifically try to reach the server over multiple ports and protocols; however, you do not see any denied connections in the firewall logs. You want to resolve the issue.
What should you do?

Enable logging on the default Deny Any Firewall Rule.

Enable logging on the VM Instances that receive traffic.

Create a logging sink forwarding all firewall logs with no filters.

Create an explicit Deny Any rule and enable logging on the new rule.

https://cloud.google.com/vpc/docs/firewall-rules-logging#egress_deny_example You can only enable Firewall Rules Logging for rules in a Virtual Private Cloud (VPC) network. Legacy networks are not supported. Firewall Rules Logging only records TCP and UDP connections. Although you can create a firewall rule applicable to other protocols, you cannot log their connections. You cannot enable Firewall Rules Logging for the implied deny ingress and implied allow egress rules. Log entries are written from the perspective of virtual machine (VM) instances. Log entries are only created if a firewall rule has logging enabled and if the rule applies to traffic sent to or from the VM. Entries are created according to the connection logging limits on a best effort basis. The number of connections that can be logged in a given interval is based on the machine type. Changes to firewall rules can be viewed in VPC audit logs. https://cloud.google.com/vpc/docs/firewall-rules-logging#specifications

NO.66 You have a Cloud Storage bucket in Google Cloud project XYZ. The bucket contains sensitive dat a. You need to design a solution to ensure that only instances belonging to VPCs under project XYZ can access the data stored in this Cloud Storage bucket. What should you do?

Configure Private Google Access to privately access the Cloud Storage service using private IP addresses.

Configure a VPC Service Controls perimeter around project XYZ, and include storage.googleapis.com as a restricted service in the service perimeter.

Configure Cloud Storage with projectPrivate Access Control List (ACL) that gives permission to the project team based on their roles.

Configure Private Service Connect to privately access Cloud Storage from all VPCs under project XYZ.

NO.67 You need to give each member of your network operations team least-privilege access to create, modify, and delete Cloud Interconnect VLAN attachments.
What should you do?

Assign each user the editor role.

Assign each user the compute.networkAdmin role.

Give each user the following permissions only: compute.interconnectAttachments.create, compute.interconnectAttachments.get.

Give each user the following permissions only: compute.interconnectAttachments.create, compute.interconnectAttachments.get, compute.routers.create, compute.routers.get, compute.routers.update.

NO.71 You are designing a Google Kubernetes Engine (GKE) cluster for your organization. The current cluster size is expected to host 10 nodes, with 20 Pods per node and 150 services. Because of the migration of new services over the next 2 years, there is a planned growth for 100 nodes, 200 Pods per node, and 1500 services. You want to use VPC-native clusters with alias IP ranges, while minimizing address consumption.
How should you design this topology?

Create a subnet of size/25 with 2 secondary ranges of: /17 for Pods and /21 for Services. Create a VPC-native cluster and specify those ranges.

Create a subnet of size/28 with 2 secondary ranges of: /24 for Pods and /24 for Services. Create a VPC-native cluster and specify those ranges. When the services are ready to be deployed, resize the subnets.

NO.73 Datachamps is an organization resource and it has many projects under it .The company uses BigQuery for data analysis. They want a user named admin-bigquery to be the admin for all BigQuery data across all of the projects under the Datachamps organization . Monitorbigquery is a service account that’s responsible for monitoring the size of all the tables across all projects in the Datachamps organization. What predefined roles must be given to admin-bigquery (user) and Monitorbigquery (service account) .

bigquery.user to admin-bigquery and bigquery.dataViewer to Monitorbigquery service

bigquery.admin to admin-bigquery and bigquery.dataViewer to Monitorbigquery service account.

bigquery.admin to admin-bigquery and bigquery.dataOwner to Monitorbigquery service account.

bigquery.connectionAdmin to admin-bigquery and bigquery.dataEditor to Monitoringbigquery service account .

Option B is the Correct choice because, On organization Datachamps add admin-bigquery to the predefined role bigquery.admin this provides permissions to manage all resources across the project and manage all data across the project, and can cancel jobs from other users running across the project.. Add Monitorbigquery to the predefined role bigquery.dataViewer ,when applied at the project or organization level, this role can also enumerate all datasets in the project and this the appropriate role to fulfil the objective of monitoring tables across all projects .
