Both of the above are true. However, the collars tend not to fail unless it's had a hard life (spirited driving/towing/very high mileage).

When viewing the car, crawl underneath and see if you can spin the propshaft with your hand. If it spins, the collar is toast and the AWD will not work.

Much less common, but my 2004 V70R had total bearing failure inside the angle gear due to improper lubrication which seems to be a known fault with these. If the oil is even slightly lower than it should be, it is not picked up sufficiently by the bevel gear and the bearing on the output shaft eats itself to pieces.

Luckily none of the actual gears were damaged, so repairing it was a case of opening it up then installing new bearings and seals. (Total about £450 with genuine Volvo parts as a DIY job.)

2 trips to the Scottish Highlands (1200~ miles each), NC500 (1600 miles) and 9 months of daily driving later, it's still going strong.
