4. Implementing hybrid interconnectivity

Configuring interconnect. Considerations include:

• Virtualizing using VLAN attachments
• Partner (e.g., layer 2 vs. layer 3 connectivity)
• Bulk storage uploads

Configuring a site-to-site IPsec VPN (e.g., route-based, policy-based, dynamic or static routing).

Configuring Cloud Router for reliability.

5. Implementing network security

Configuring identity and access management (IAM). Tasks include:

• Defining custom IAM roles
• Assigning IAM roles to accounts or Google Groups
• Using pre-defined IAM roles (e.g., network admin, network viewer, network user)
• Viewing account IAM assignments

Configuring Cloud Armor policies. Considerations include:

Configuring third-party device insertion into VPC using multi-nic (NGFW)

Managing keys for SSH access

6. Managing and monitoring network operations

Logging and monitoring with Stackdriver or GCP Console

Managing and maintaining security. Considerations include:

• Firewalls (e.g., cloud-based, private)
• Diagnosing and resolving IAM issues (shared VPC, security/network admin)

Maintaining and troubleshooting connectivity issues. Considerations include:

• Draining and redirecting traffic flows

Manage & Monitor Network Operations

In this part of the exam content, the students should be able to log and monitor with the use of GCP Console or Stackdriver. They must have competence in the management and maintenance of security, which includes firewalls and diagnosing & resolving IAM problems. Besides that, they need to be able to deal with the following objective:

• Maintain & Troubleshoot Connectivity Issues: It includes the identification of traffic flow topology, redirecting and draining of traffic flows, and cross-connect hand-off for interconnect. It also measures one’s knowledge of the monitoring of egress and ingress traffic with the use of flow logs as well as monitoring firewall logs. This section will also evaluate the learners’ skills in troubleshooting and managing VPNs and troubleshooting peering issues with Cloud Router BGP.
