Scenario: A load-balancing vServer is configured to utilize the least bandwidth load-balancing method. A service attached to this vServer is brought into the effective state during production hours.
During the startup of a vServer, which load-balancing method is used by default?
During the startup of a virtual server, the default load-balancing method used is round-robin. This approach helps distribute the initial client requests evenly across the servers to prevent any single server from being overloaded initially. This method ensures a fair distribution of load until the configured load-balancing method, such as least connections or least bandwidth, takes over handling the requests according to the specified criteria.
I think its D, slow start round-robin kicks in when there are changes certain changes to avoid surge of connections https://support.citrix.com/article/CTX108886
agree with you. even if it was least connection it will round robin when effective state changed to up
From official exam guide During startup of a virtual server, or whenever the state of a virtual server changes, the virtual server can initially use the round-robin method to distribute the client requests among the physical servers. This type of distribution, referred to as startup round robin, helps prevent unnecessary load on a single server as the initial requests are served. After using the round-robin method at the startup, the virtual server switches to the loadbalancing method specified on the virtual server
B. I think question is tricky. Slow start is not enabled by default and if RR=0 configured LB method is used. https://docs.netscaler.com/en-us/citrix-adc/current-release/load-balancing/load-balancing-customizing-algorithms.html The Startup RR Factor works in the following manner: -If the Startup RR Factor is set to zero, the appliance switches to the specified load balancing method depending on the request rate. -If the Startup RR Factor is any number other than zero, the appliance uses the round robin method for the specified number of requests before switching to the specified load balancing method. -By default, the Startup RR Factor is set to zero.
D (Roun Robin) is the correct answer. Refering to https://support.citrix.com/article/CTX108886/netscaler-load-balancing-slow-start-mode By default, the newly configured virtual server remains in a Slow Start mode for Startup RR Factor of 100. To avoid overloading of servers, the appliance performs Slow Start. During this phase, the appliance distributes the requests by the Round Robin method regardless of the actual method configured.
D is the answer as it will use RoundRbin when starting up as lease connection will over commit connections to the new server https://support.citrix.com/article/CTX108886/,

Answer A it´s OK
Its A, by default method is Least connections
check with u bro, you pass the exam bro?
