Question # 4

Your company's security team tends to use managed services when possible. You need to build a dashboard to show the number of deny hits that occur against configured firewall rules without increasing operational overhead. What should you do?

Options:

A.

Configure Firewall Rules Logging. Use Firewall Insights to display the number of hits.

B.

Configure Firewall Rules Logging. View the logs in Cloud Logging, and create a custom dashboard in Cloud Monitoring to display the number of hits.

C.

Configure a firewall appliance from the Google Cloud Marketplace. Route all traffic through this appliance, and apply the firewall rules at this layer. Use the firewall appliance to display the number of hits.

D.

Configure Packet Mirroring on the VPC. Apply a filter with an IP address list of the Denied Firewall rules. Configure an intrusion detection system (IDS) appliance as the receiver to display the number of hits.

How should you provision your instances?

Options:

A.

Create a single managed instance group, specify the desired region, and select Multiple zones for the location.

B.

Create a managed instance group for each region, select Single zone for the location, and manually distribute instances across the zones in that region.

C.

Create an unmanaged instance group in a single zone, and then create an HTTP load balancer for the instance group.

D.

Create an unmanaged instance group for each zone, and manually distribute the instances across the desired zones.

Options:

A.

Enable Data Access audit logs of the VPC. Analyze the logs and get the source IP addresses from the subnetworks.get field.

B.

Enable VPC Flow Logs for the subnet. Analyze the logs and get the source IP addresses from the connection field.

C.

Enable VPC Flow Logs for the VPC. Analyze the logs and get the source IP addresses from the src_location field.

D.

Enable Data Access audit logs of the subnet. Analyze the logs and get the source IP addresses from the networks.get field.

Question:

Recently, your networking team enabled Cloud CDN for one of the external-facing services that is exposed through an external Application Load Balancer. The application team has already defined which content should be cached within the responses. Upon testing the load balancer, you did not observe any change in performance after the Cloud CDN enablement. You need to resolve the issue. What should you do?

Options:

A.

Configure the CACHE_MAX_STATIC caching mode on Cloud CDN to ensure Cloud CDN caches content depending on responses from the backends.

B.

Configure the USE_ORIGIN_HEADERS caching mode on Cloud CDN to ensure Cloud CDN caches content based on response headers from the backends.

C.

Configure the CACHE_ALL_STATIC caching mode on Cloud CDN to ensure Cloud CDN caches all static content as well as content defined by the backends.

D.

Configure the FORCE_CACHE_ALL caching mode on Cloud CDN to ensure all appropriate content is cached.

B.

Configure the Resource Manager constraint constraints/compute.restrictVpnPeerIPs to use an allowList consisting of only the 203.0.113.1/32 address.

C.

Configure a Google Cloud Armor security policy, and create a policy rule to allow 203.0.113.1/32.

D.

Configure an access control list on the peer VPN gateway to deny all traffic except 203.0.113.1/32, and attach it to the primary external interface.
