I am working towards CCNP and starting to build home lab. Just want to know that Cisco WS-C3524-XL-EN is a layer 3 switch and suitable for CCNP labs ? If not, also advise me what switch would be suitable for CCNP level.
No it is not , it's an ancient L2 switch that was built in the mid 1990's for the access layer . If you need a layer 3 switchg for a lab I would look for a 3550, though this is also end of life it should fit your need for L3 functionality though it might not have the latest QOS, COS functionality of something like a 3560 switch with ipservices which would cost more than most people would want to invest in for a lab.
