A Citrix Administrator would like to use an existing monitor script included in NetScaler for load
balancing TFTP services in a Provisioning Services deployment.
Which monitor type should the administrator choose in order to complete the task?
A.
ARP
B.
USER
C.
TCP-ECV
D.
UDP-ECV
Questions ask: “existing monitor”:
Since TFTP uses UDP, one applicable monitor here would be udp-ecv, which sends a UDP request over the service’s configured port and looks for a response.
For those who want a “cleaner” or more exact TFTP monitor, it is possible to load a custom script to probe the TFTP service for the .bin file
