Is it possible to compare structures using memcmp if one assures that the pad bytes are always 0? I mean;

struct test a, b;

memset(&a, 0, sizeof(struct test));
memset(&b, 0, sizeof(struct test));

/* Code to set a and b values here */

if (memcmp(a, b, sizeof(struct test))) {
    /* do something */
}

What i'm indirectly asking is: Are the members of both structs (a and b) assured to be padded the same way??

In that case, yes.
