Questions # 31:

You are troubleshooting an issue where your organization's Cloud HA VPN is disconnected from your on-premises router for approximately 10 seconds before reestablishing the tunnel. The issue regularly occurs every few hours. You notice that the HA VPN logs show an entry of Received SA_DELETE when this issue occurs. You need to resolve this issue and prevent future VPN downtime from impacting your production applications. What should you do?

Options:

A.

Q Update the pre-shared key (PSK) of the on-premises router’s VPN tunnel configuration to match the PSK of the Cloud HA VPN.


B.

Q Update the on-premises router’s BGP router ID to reflect the link-local IP peer address assigned by Cloud Router.


C.

Q Update the on-premises router’s Phase 1 and Phase 2 lifetime IKE parameters to match the values in the Cloud HA VPN documentation.


D.

Q Update the on-premises router’s Diffie-Hellman groups and cipher proposal list to match the values in the Cloud HA VPN documentation.

Questions # 32:

Your company has provisioned 2000 virtual machines (VMs) in the private subnet of your Virtual Private Cloud (VPC) in the us-east1 region. You need to configure each VM to have a minimum of 128 TCP connections to a public repository so that users can download software updates and packages over the internet. You need to implement a Cloud NAT gateway so that the VMs are able to perform outbound NAT to the internet. You must ensure that all VMs can simultaneously connect to the public repository and download software updates and packages. Which two methods can you use to accomplish this? (Choose two.)

Options:

A.

Configure the NAT gateway in manual allocation mode, allocate 2 NAT IP addresses, and update the minimum number of ports per VM to 256.


B.

Create a second Cloud NAT gateway with the default minimum number of ports configured per VM to 64.


C.

Use the default Cloud NAT gateway's NAT proxy to dynamically scale using a single NAT IP address.


D.

Use the default Cloud NAT gateway to automatically scale to the required number of NAT IP addresses, and update the minimum number of ports per VM to 128.


E.

Configure the NAT gateway in manual allocation mode, allocate 4 NAT IP addresses, and update the minimum number of ports per VM to 128.

Questions # 33:

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?

Options:

A.

Update the TTL for the zone.


B.

Set the zone to the TRANSFER state.


C.

Disable DNSSEC at your domain registar.


D.

Transfer ownership of the domain to a new registar.

Questions # 34:

Your on-premises data center has 2 routers connected to your Google Cloud environment through a VPN on each router. All applications are working correctly; however, all of the traffic is passing across a single VPN instead of being load-balanced across the 2 connections as desired.

During troubleshooting you find:

• Each on-premises router is configured with a unique ASN.

• Each on-premises router is configured with the same routes and priorities.

• Both on-premises routers are configured with a VPN connected to a single Cloud Router.

• BGP sessions are established between both on-premises routers and the Cloud Router.

• Only 1 of the on-premises router’s routes are being added to the routing table.

What is the most likely cause of this problem?

Options:

A.

The on-premises routers are configured with the same routes.


B.

A firewall is blocking the traffic across the second VPN connection.


C.

You do not have a load balancer to load-balance the network traffic.


D.

The ASNs being used on the on-premises routers are different.

Questions # 35:

Your company has a single Virtual Private Cloud (VPC) network deployed in Google Cloud with on-premises connectivity already in place. You are deploying a new application using Google Kubernetes Engine (GKE), which must be accessible only from the same VPC network and on-premises locations. You must ensure that the GKE control plane is exposed to a predefined list of on-premises subnets through private connectivity only. What should you do?

Options:

A.

Create a GKE private cluster with a private endpoint for the control plane. Configure VPC Networking Peering export/import routes and custom route advertisements on the Cloud Routers. Configure authorized networks to specify the desired on-premises subnets.


B.

Create a GKE private cluster with a public endpoint for the control plane. Configure VPC Networking Peering export/import routes and custom route advertisements on the Cloud Routers.


C.

Create a GKE private cluster with a private endpoint for the control plane. Configure authorized networks to specify the desired on-premises subnets.


D.

Create a GKE public cluster. Configure authorized networks to specify the desired on-premises subnets.

Questions # 36:

You have just deployed your infrastructure on Google Cloud. You now need to configure the DNS to meet the following requirements:

Your on-premises resources should resolve your Google Cloud zones.

Your Google Cloud resources should resolve your on-premises zones.

You need the ability to resolve “. internal” zones provisioned by Google Cloud.

What should you do?

Options:

A.

Configure an outbound server policy, and set your alternative name server to be your on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google's public DNS 8.8.8.8.


B.

Configure both an inbound server policy and outbound DNS forwarding zones with the target as the on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google Cloud's DNS resolver.


C.

Configure an outbound DNS server policy, and set your alternative name server to be your on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google Cloud's DNS resolver.


D.

Configure Cloud DNS to DNS peer with your on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google's public DNS 8.8.8.8.

Questions # 39:

Your organization wants to set up hybrid connectivity with VLAN attachments that terminate in a single Cloud Router with 99.9% uptime.

What should you do?

Options:

A.

Create a design that uses a BGP multi-exit discriminator (MED) attribute to influence the egress path from Google Cloud to the on-premises environment.
