NEW QUESTION 23
Your company has just launched a new critical revenue-generating web application. You deployed the application for scalability using managed instance groups, autoscaling, and a network load balancer as frontend. One day, you notice severe bursty traffic that caused autoscaling to reach the maximum number of instances, and users of your application cannot complete transactions. After an investigation, you think it is a DDOS attack. You want to quickly restore user access to your application and allow successful transactions while minimizing cost.
Which two steps should you take? (Choose two.)

Use Cloud Armor to blacklist the attacker’s IP addresses.

Increase the maximum autoscaling backend to accommodate the severe bursty traffic.

Create a global HTTP(s) load balancer and move your application backend to this load balancer.

Shut down the entire application in GCP for a few hours. The attack will stop when the application is offline.

SSH into the backend compute engine instances, and view the auth logs and syslogs to further understand the nature of the attack.

NEW QUESTION 24
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.

Which two solutions can you implement to achieve the desired results without compromising the security? (Choose two.)

VPC peering

Shared VPC

Cloud VPN

Dedicated Interconnect

Cloud NAT

Google Cloud VPC Network Peering allows internal IP address connectivity across two Virtual Private Cloud (VPC) networks regardless of whether they belong to the same project or the same organization.

NEW QUESTION 34
You have configured Cloud CDN using HTTP(S) load balancing as the origin for cacheable content. Compression is configured on the web servers, but responses served by Cloud CDN are not compressed.
What is the most likely cause of the problem?

You have not configured compression in Cloud CDN.

You have configured the web servers and Cloud CDN with different compression types.

The web servers behind the load balancer are configured with different compression types.

You have to configure the web servers to compress responses even if the request has a Via header.

If responses served by Cloud CDN are not compressed but should be, check that the web server software running on your instances is configured to compress responses. By default, some web server software will automatically disable compression for requests that include a Via header. The presence of a Via header indicates the request was forwarded by a proxy. HTTP proxies such as HTTP(S) load balancing add a Via header to each request as required by the HTTP specification.
To enable compression, you may have to override your web server’s default configuration to tell it to compress responses even if the request had a Via header.

NEW QUESTION 35
You are designing a shared VPC architecture. Your network and security team has strict controls over which routes are exposed between departments. Your Production and Staging departments can communicate with each other, but only via specific networks. You want to follow Google-recommended practices.
How should you design this topology?

Create 2 shared VPCs within the shared VPC Host Project, and enable VPC peering between them. Use firewall rules to filter access between the specific networks.

Create 2 shared VPCs within the shared VPC Host Project, and create a Cloud VPN/Cloud Router between them. Use Flexible Route Advertisement (FRA) to filter access between the specific networks.

Create 2 shared VPCs within the shared VPC Service Project, and create a Cloud VPN/Cloud Router between them. Use Flexible Route Advertisement (FRA) to filter access between the specific networks.

Create 1 VPC within the shared VPC Host Project, and share individual subnets with the Service Projects to filter access between the specific networks.

NEW QUESTION 36
You need to enable Cloud CDN for all the objects inside a storage bucket. You want to ensure that all the object in the storage bucket can be served by the CDN.
What should you do in the GCP Console?

Create a new cloud storage bucket, and then enable Cloud CDN on it.

Create a new TCP load balancer, select the storage bucket as a backend, and then enable Cloud CDN on the backend.

Create a new SSL proxy load balancer, select the storage bucket as a backend, and then enable Cloud CDN on the backend.

Create a new HTTP load balancer, select the storage bucket as a backend, enable Cloud CDN on the backend, and make sure each object inside the storage bucket is shared publicly.

NEW QUESTION 37

Grant the cloud-platform privilege to the service account for the Cloud Storage bucket.

NEW QUESTION 38
Your software team is developing an on-premises web application that requires direct connectivity to Compute Engine Instances in GCP using the RFC 1918 address space. You want to choose a connectivity solution from your on-premises environment to GCP, given these specifications:
* Your ISP is a Google Partner Interconnect provider.
* Your on-premises VPN device’s internet uplink and downlink speeds are 10 Gbps.
* A test VPN connection between your on-premises gateway and GCP is performing at a maximum speed of
500 Mbps due to packet losses.
* Most of the data transfer will be from GCP to the on-premises environment.
* The application can burst up to 1.5 Gbps during peak transfers over the Interconnect.
* Cost and the complexity of the solution should be minimal.
How should you provision the connectivity solution?

Provision a Partner Interconnect through your ISP.

Provision a Dedicated Interconnect instead of a VPN.

Create multiple VPN tunnels to account for the packet losses, and increase bandwidth using ECMP.

Use network compression over your VPN to increase the amount of data you can send over your VPN.

NEW QUESTION 39
You are disabling DNSSEC for one of your Cloud DNS-managed zones. You removed the DS records from your zone file, waited for them to expire from the cache, and disabled DNSSEC for the zone. You receive reports that DNSSEC validating resolves are unable to resolve names in your zone.
What should you do?

Update the TTL for the zone.

Set the zone to the TRANSFER state.

Disable DNSSEC at your domain registar.

Transfer ownership of the domain to a new registar.

Before disabling DNSSEC for a managed zone you want to use, you must deactivate DNSSEC at your domain registrar to ensure that DNSSEC-validating resolvers can still resolve names in the zone.
