You can see the recruitment on the Internet, and the requirements for Google certification are getting higher and higher. As the old saying goes, skills will never be burden. So for us, with one more certification, we will have one more bargaining chip in the future. However, it is difficult for many people to get a Google certification, because the busy people seldom have much time to read the books they need. So how should people solve this problem? At this time, people should to need some good study materials. Not only will our study materials help you pass exam, but it will also save your valuable time. Now let me introduce our Professional-Cloud-Network-Engineer exam questions to you in detail.

Implement Network Security

• Configure IAM (Identity & Access Management): The technical tasks that will be measured in this domain include viewing account Identity & Access Management assigning, using IAM pre-defined roles, identifying IAM custom roles, and assigning IAM to Google Groups or accounts;
• Configure Cloud Armor Policies: This one will measure your skills in IP-based access control.

The exam will also evaluate your competence in the configuration of the 3rd-party device insertion into VPC with the use of multi-nic. It will measure your skills in managing the keys for SSH access.

3. Configuring network services

Configuring load balancing. Considerations include:

• Firewall and security rules
• Session affinity
• Capacity scaling
• Network load balancer
• Internal load balancer
• HTTP(S) load balancer: including changing URL maps, backend groups, health checks, CDN, and SSL certs
• TCP and SSL proxy load balancers
• Creating backend services

Configuring Cloud CDN. Considerations include:

• Enabling and disabling Cloud CDN
• Signed URLs
• Using cache keys
• Cache invalidation

Configuring and maintaining Cloud DNS. Considerations include:

• Migrating to Cloud DNS
• Internal DNS
• Cloud DNS

• Integrating on-premises DNS with GCP
• DNS Security (DNSSEC)
• Global serving with Anycast

Enabling other network services. Considerations include:

• Enabling private API access
• Canary (A/B) releases
• Health checks for your instance groups
• Distributing backend instances using regional managed instance groups

4. Implementing hybrid interconnectivity

Configuring interconnect. Considerations include:

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