Questions # 61:

You have provisioned a Dedicated Interconnect connection of 20 Gbps with a VLAN attachment of 10 Gbps. You recently noticed a steady increase in ingress traffic on the Interconnect connection from the on-premises data center. You need to ensure that your end users can achieve the full 20 Gbps throughput as quickly as possible. Which two methods can you use to accomplish this? (Choose two.)

Options:

Configure an additional VLAN attachment of 10 Gbps in another region. Configure the on-premises router to advertise routes with the same multi-exit discriminator (MED).

Configure an additional VLAN attachment of 10 Gbps in the same region. Configure the on-premises router to advertise routes with the same multi-exit discriminator (MED).

From the Google Cloud Console, modify the bandwidth of the VLAN attachment to 20 Gbps.

From the Google Cloud Console, request a new Dedicated Interconnect connection of 20 Gbps, and configure a VLAN attachment of 10 Gbps.

Configure Link Aggregation Control Protocol (LACP) on the on-premises router to use the 20-Gbps Dedicated Interconnect connection.

Questions # 62:

There are two established Partner Interconnect connections between your on-premises network and Google Cloud. The VPC that hosts the Partner Interconnect connections is named "vpc-a" and contains three VPC subnets across three regions, Compute Engine instances, and a GKE cluster. Your on-premises users would like to resolve records hosted in a Cloud DNS private zone following Google-recommended practices. You need to implement a solution that allows your on-premises users to resolve records that are hosted in Google Cloud. What should you do?

Options:

Associate the private zone to "vpc-a." Create an outbound forwarding policy and associate the policy to "vpc-a." Configure the on-premises DNS servers to forward queries for the private zone to the entry point addresses created when the policy was attached to "vpc-a."

Configure a DNS proxy service inside one of the GKE clusters. Expose the DNS proxy service in GKE as an internal load balancer. Configure the on-premises DNS servers to forward queries for the private zone to the IP address of the internal load balancer.

Use custom route advertisements to announce 169.254.169.254 via BGP to the on-premises environment. Configure the on-premises DNS servers to forward DNS requests to 169.254.169.254.

Associate the private zone to "vpc-a." Create an inbound forwarding policy and associate the policy to "vpc-a." Configure the on-premises DNS servers to forward queries for the private zone to the entry point addresses created when the policy was attached to "vpc-a."

Questions # 63:

Question:

Your organization has an on-premises data center. You need to provide connectivity from the on-premises data center to Google Cloud. Bandwidth must be at least 1 Gbps, and the traffic must not traverse the internet. What should you do?

Options:

Configure HA VPN by using high availability gateways and tunnels.

Configure Dedicated Interconnect by creating a VLAN attachment, activate the connection, and submit the pairing key to your service provider.

Configure Cross-Cloud Interconnect by creating a VLAN attachment, activate the connection, and then submit the pairing key to your service provider.

Configure Partner Interconnect by creating a VLAN attachment, submit the pairing key to your service provider, and activate the connection.

Questions # 64:

You have the networking configuration shown in the diagram. A pair of redundant Dedicated Interconnect connections (int-Igal and int-Iga2) terminate on the same Cloud Router. The Interconnect connections terminate on two separate on-premises routers. You are advertising the same prefixes from the Border Gateway Protocol (BGP) sessions associated with the Dedicated Interconnect connections. You need to configure one connection as Active for both ingress and egress traffic. If the active Interconnect connection fails, you want the passive Interconnect connection to automatically begin routing all traffic Which two actions should you take to meet this requirement? (Choose Two)

Question # 64

Options:

Configure the advertised route priority > 10,200 on the active Interconnect connection.

Advertise a lower MED on the passive Interconnect connection from the on-premises router

Configure the advertised route priority as 200 for the BGP session associated with the active Interconnect connection.

Configure the advertised route priority as 200 for the BGP session associated with the passive Interconnect connection.

Advertise a lower MED on the active Interconnect connection from the on-premises router

Answer

C, E

Explanation

This answer meets the requirement of configuring one connection as Active for both ingress and egress traffic, and enabling automatic failover to the passive connection in case of failure. The reason is:

The advertised route priority is a value that Cloud Router uses to set the route priority when advertising routes to your on-premises router. The lower the value, the higher the priority1. By setting the advertised route priority as 200 for the active connection, you ensure that it has a higher priority than the passive connection, which has the default value of 1001. This way, your on-premises router will prefer the routes from the active connection over the passive one for ingress traffic.

The MED (Multi-Exit Discriminator) is a value that your on-premises router uses to indicate its preference for receiving traffic from Cloud Router. The lower the value, the higher the preference2. By advertising a lower MED on the active connection from your on-premises router, you ensure that Cloud Router will prefer sending traffic to the active connection over the passive one for egress traffic.

If the active connection fails, Cloud Router will stop receiving routes from it and will start using the routes from the passive connection for egress traffic. Similarly, your on-premises router will stop receiving routes with priority 200 from the active connection and will start using the routes with priority 100 from the passive connection for ingress traffic. This achieves automatic failover without any manual intervention.

Option A is incorrect because setting the advertised route priority > 10,200 on the active connection would deprioritize it globally in your VPC network, which is not what you want1. Option B is incorrect because advertising a lower MED on the passive connection would make Cloud Router prefer sending traffic to it over the active one, which is not what you want2. Option D is incorrect because setting the advertised route priority as 200 for both connections would make them equally preferred by your on-premises router, which is not what you want1.

Questions # 65:

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:

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

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

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.

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.

Questions # 66:

You want to set up two Cloud Routers so that one has an active Border Gateway Protocol (BGP) session, and the other one acts as a standby.

Which BGP attribute should you use on your on-premises router?

Options:

AS-Path

Community

Local Preference

Multi-exit Discriminator

Questions # 67:

Question:

You are configuring the firewall endpoints as part of the Cloud Next Generation Firewall (Cloud NGFW) intrusion prevention service in Google Cloud. You have configured a threat prevention security profile, and you now need to create an endpoint for traffic inspection. What should you do?

Options:

Attach the profile to the VPC network, create a firewall endpoint within the zone, and use a firewall policy rule to apply the L7 inspection.

Create a firewall endpoint within the zone, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.

Create a firewall endpoint within the region, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.

Create a Private Service Connect endpoint within the zone, associate the endpoint to the VPC network, and use a firewall policy rule to apply the L7 inspection.
