Question # 61

Question:

Your organization has distributed geographic applications with significant data volumes. You need to create a design that exposes the HTTPS workloads globally and keeps traffic costs to a minimum. What should you do?

Deploy a regional external Application Load Balancer with Standard Network Service Tier.

Deploy a regional external Application Load Balancer with Premium Network Service Tier.

Deploy a global external proxy Network Load Balancer with Standard Network Service Tier.

Deploy a global external Application Load Balancer with Premium Network Service Tier.

Question # 62

You are troubleshooting an application in your organization's Google Cloud network that is not functioning as expected. You suspect that packets are getting lost somewhere. The application sends packets intermittently at a low volume from a Compute Engine VM to a destination on your on-premises network through a pair of Cloud Interconnect VLAN attachments. You validated that the Cloud Next Generation Firewall (Cloud NGFW) rules do not have any deny statements blocking egress traffic, and you do not have any explicit allow rules. Following Google-recommended practices, you need to analyze the flow to see if packets are being sent correctly out of the VM to isolate the issue. What should you do?

Create a packet mirroring policy that is configured with your VM as the source and destined to a collector. Analyze the packet captures.

Enable VPC Flow Logs on the subnet that the VM is deployed in with sample_rate = 1.0, and run a query in Logs Explorer to analyze the packet flow.

Enable Firewall Rules Logging on your firewall rules and review the logs.

Verify the network/attachment/egress_dropped_packet.s_count Cloud Interconnect VLAN attachment metric.

Question # 63

You recently configured Google Cloud Armor security policies to manage traffic to your application. You discover that Google Cloud Armor is incorrectly blocking some traffic to your application. You need to identity the web application firewall (WAF) rule that is incorrectly blocking traffic. What should you do?

Enable firewall logs, and view the logs in Firewall Insights.

Enable HTTP(S) Load Balancing logging with sampling rate equal to 1, and view the logs in Cloud Logging.

Enable VPC Flow Logs, and view the logs in Cloud Logging.

Enable Google Cloud Armor audit logs, and view the logs on the Activity page in the Google Cloud Console.

Question # 64

Your organization uses a hub-and-spoke architecture with critical Compute Engine instances in your Virtual Private Clouds (VPCs). You are responsible for the design of Cloud DNS in Google Cloud. You need to be able to resolve Cloud DNS private zones from your on-premises data center and enable on-premises name resolution from your hub-and-spoke VPC design. What should you do?

Configure a private DNS zone in the hub VPC, and configure DNS forwarding to the on-premises server.

Configure DNS peering from the spoke VPCs to the hub VPC.

Configure a DNS policy in the hub VPC to allow inbound query forwarding from the spoke VPCs.

Configure the spoke VPCs with a private zone, and set up DNS peering to the hub VPC.

Configure a DNS policy in the spoke VPCs, and configure your on-premises DNS as an alternate DNS server.

Configure the hub VPC with a private zone, and set up DNS peering to each of the spoke VPCs.

Configure a DNS policy in the hub VPC, and configure the on-premises DNS as an alternate DNS server.

Configure the spoke VPCs with a private zone, and set up DNS peering to the hub VPC.

Question # 65

Your company’s Google Cloud-deployed, streaming application supports multiple languages. The application development team has asked you how they should support splitting audio and video traffic to different backend Google Cloud storage buckets. They want to use URL maps and minimize operational overhead. They are currently using the following directory structure:

/fr/video

/en/video

/es/video

/../video

/fr/audio

/en/audio

/es/audio

/../audio

Which solution should you recommend?

Rearrange the directory structure, create a URL map and leverage a path rule such as /video/* and /audio/*.

Rearrange the directory structure, create DNS hostname entries for video and audio and leverage a path rule such as /video/* and /audio/*.

Leave the directory structure as-is, create a URL map and leverage a path rule such as \/[a-z]{2}\/video and

\/[a-z]{2}\/audio.

Leave the directory structure as-is, create a URL map and leverage a path rule such as /*/video and /*/ audio.

Question # 66

You are migrating a three-tier application architecture from on-premises to Google Cloud. As a first step in the migration, you want to create a new Virtual Private Cloud (VPC) with an external HTTP(S) load balancer. This load balancer will forward traffic back to the on-premises compute resources that run the presentation tier. You need to stop malicious traffic from entering your VPC and consuming resources at the edge, so you must configure this policy to filter IP addresses and stop cross-site scripting (XSS) attacks. What should you do?

Create a Google Cloud Armor policy, and apply it to a backend service that uses an unmanaged instance group backend.

Create a hierarchical firewall ruleset, and apply it to the VPC's parent organization resource node.

Create a Google Cloud Armor policy, and apply it to a backend service that uses an internet network endpoint group (NEG) backend.

Create a VPC firewall ruleset, and apply it to all instances in unmanaged instance groups.

Question # 67

You are using a 10-Gbps direct peering connection to Google together with the gsutil tool to upload files to Cloud Storage buckets from on-premises servers. The on-premises servers are 100 milliseconds away from the Google peering point. You notice that your uploads are not using the full 10-Gbps bandwidth available to you. You want to optimize the bandwidth utilization of the connection.

What should you do on your on-premises servers?

Tune TCP parameters on the on-premises servers.

Compress files using utilities like tar to reduce the size of data being sent.

Remove the -m flag from the gsutil command to enable single-threaded transfers.

Use the perfdiag parameter in your gsutil command to enable faster performance: gsutil perfdiag gs://[BUCKET NAME].
