Your company is running out of network capacity to run a critical application in the on-premises data center. You want to migrate the application to GCP. You also want to ensure that the Security team does not lose their ability to monitor traffic to and from Compute Engine instances.

Which two products should you incorporate into the solution? (Choose two.)

  1. VPC flow logs
  2. Firewall logs
  3. Cloud Audit logs
  4. Stackdriver Trace
  5. Compute Engine instance system logs

Answer(s): A,B

Explanation:

A: Using VPC Flow Logs VPC Flow Logs records a sample of network flows sent from and received by VM instances, including instances used as GKE nodes. These logs can be used for network monitoring, forensics, real-time security analysis, and expense optimization. https://cloud.google.com/vpc/docs/using-flow-logs (B): Firewall Rules Logging overview Firewall Rules Logging allows you to audit, verify, and analyze the effects of your firewall rules. For example, you can determine if a firewall rule designed to deny traffic is functioning as intended. Firewall Rules Logging is also useful if you need to determine how many connections are affected by a given firewall rule. You enable Firewall Rules Logging individually for each firewall rule whose connections you need to log. Firewall Rules Logging is an option for any firewall rule, regardless of the action (allow or deny) or direction (ingress or egress) of the rule. https://cloud.google.com/vpc/docs/firewall-rules-logging



You want to apply a new Cloud Armor policy to an application that is deployed in Google Kubernetes Engine (GKE). You want to find out which target to use for your Cloud Armor policy.

Which GKE resource should you use?

  1. GKE Node
  2. GKE Pod
  3. GKE Cluster
  4. GKE Ingress

Answer(s): D

Explanation:

Cloud Armour is applied at load balancers Configuring Google Cloud Armor through Ingress. https://cloud.google.com/kubernetes-engine/docs/how-to/ingress-features Security policy features Google Cloud Armor security policies have the following core features: You can optionally use the QUIC protocol with load balancers that use Google Cloud Armor. You can use Google Cloud Armor with external HTTP(S) load balancers that are in either Premium Tier or Standard Tier. You can use security policies with GKE and the default Ingress controller.



You need to establish network connectivity between three Virtual Private Cloud networks, Sales, Marketing, and Finance, so that users can access resources in all three VPCs. You configure VPC peering between the Sales VPC and the Finance VPC. You also configure VPC peering between the Marketing VPC and the Finance VPC. After you complete the configuration, some users cannot connect to resources in the Sales VPC and the Marketing VPC. You want to resolve the problem.

What should you do?

  1. Configure VPC peering in a full mesh.
  2. Alter the routing table to resolve the asymmetric route.
  3. Create network tags to allow connectivity between all three VPCs.
  4. Delete the legacy network and recreate it to allow transitive peering.

Answer(s): A

Explanation:

You create multiple Compute Engine virtual machine instances to be used as TFTP servers.

Which type of load balancer should you use?

  1. HTTP(S) load balancer
  2. SSL proxy load balancer
  3. TCP proxy load balancer
  4. Network load balancer

Answer(s): D

Explanation:

"TFTP is a UDP-based protocol. Servers listen on port 69 for the initial client-to-server packet to establish the TFTP session, then use a port above 1023 for all further packets during that session. Clients use ports above 1023" https://docstore.mik.ua/orelly/networking_2ndEd/fire/ch17_02.htm Besides, Google Cloud external TCP/UDP Network Load Balancing (after this referred to as Network Load Balancing) is a regional, non-proxied load balancer. Network Load Balancing distributes traffic among virtual machine (VM) instances in the same region in a Virtual Private Cloud (VPC) netw
