Answer the following questions:
- Identify any three types of load balancing algorithms.
- (a) What are the advantages of client-side load balancing? (b) What are the advantages of server-side load balancing?
- What are the two modes of load balancing supported by the built-in pfSense load balancer?
- If I am using pfSense's load balancer and I add a server to a server pool but no traffic from outside the network is reaching the new server (and traffic from outside the network is reaching other servers within the pool), what is the likely cause? Assume that my server pool setup was functioning correctly before I added the server.
- Identify which of the following can be synchronized using pfSense's High Availability Sync. (a) firewall rules; (b) packages; (c) virtual IPs; (d) system logs.
- In a normal CARP configuration, do we need to create a virtual IP for the PFSYNC interface? Why or why not?
- Assume we have a functioning CARP failover group in which all options are selected in Select options to sync on the System | High Availability Sync page. On the backup firewall, we create a new firewall rule. What happens to this rule when we navigate to Status | Filter Reload and on the master firewall and click on the Force Config Sync button?
- Why is it important to set the Advertising frequency in a CARP setup with multiple backup firewalls?
- Assume you are required to implement load balancing on a pfSense firewall using the Least Connections algorithm. What is the easiest way of achieving this?
- Assume that we need to keep CARP disabled through a reboot. How do we do this?
