Mulesoft Integration Architect- Questionsand Answers
Where can you set a VPC with a DLBs? Correct Ans-VPC can remain completely isolated from
external networks:
- Usually a VPC uses one or more dedicated load balancers to route traffic with external public
and private networks
- A DLB can handle Mule event payloads up to 200MB
How can you connect VPCs? Correct Ans-1. Configure customized firewall rules for Mule
applications deployed into the VPC:
- Open ports beside 80, 8081, 8082
- Block direct connections to CloudHub workers over port 8081 or 8082
- Allow or restrict any other TCP or UDP ports
2. Connect a VPC to a corporate intranet
- On-Prem or Clouds
- Via VPM connection to a private network
3. Connect your VPC to another AWS VPC using VPC Peering
How can you hide DLB hostnames? Correct Ans-- A DLB DNS entries are A records and are
maintained by Mulesoft
- Customers can define their own domain names as CNAMEs in their own DNS server
,What is important about the VPC sizing? Correct Ans-- Mule applications are deployed in
CloudHub workers and each worker is assigned with a dedicated IP
- For zero downtime deployment each worker in CloudHub needs additional IP addresses
- A few IPs in a VPC are reserved for infrastructure
- The IP addresses are usually in a private range with a subnet block specifier such as
10.0.0.1/24
What is the smallest and largest CIDR network subnet block you can assign for your VPC?
Correct Ans-CIDR = Classless interdomain routing
smallest: /24 = 256 IP addresses
largest: /16 = I 65536 IP addresses
If you have:
- 4 different environments: Dev, staging, performance and production
- 50 application deployed in each environment
- Two separate VPCs for production and non-production environments
- In performance and production environment each Mule application will be deployed to two
workers
,What is the minimum CIDR network subnet for each of the VPCs? (non-prod and prod)
Correct Ans-IP addresses
50 dev
50 staging
50 + 50 performance --> due to 2 workers per application
50 + 50 prod --> due to 2 workers per application
300 IPs + zero downtime 50% (150) = 450
- /23 = 510 IPs so you select /23
Remember you can configure a VPC with any CIDR subnet between /24 and /16 without any
additional costs
- You should plan for worst case growth
