This is a great question that I've been interested in for a while, but I haven't come up on much solid information about it. Early medieval Scandinavians made pictures of women serving drinking horns (similar to a scene from Beowulf, which JRR Tolkien copied into the Lord of the Rings), but we don't really know what was in them. A few hundred years later and half an ocean away, Icelandic Christians wrote down their versions of the Old Norse myths, and mead figured prominently in these. This makes a lot of sense: Iceland isn't a good place for beekeeping (bees have only been kept experimentally in Iceland since the 1930s) so mead could figure symbolically as an elite drink par excellence, perhaps even worthy of the old pagan gods. But historically, who knows? Nevertheless, historians in the 1800s and early 1900s read these myths as accurate representations of Viking Age society, so they remain the basis for popular images today.

That's not to say that Viking Age Scandinavians didn't keep bees, didn't cultivate honey, or didn't make mead. They probably did all these things. The earliest apiary laws that I know of date from the 600s in Spain (the Visigothic code), which precedes the Viking Age by 200 years. At the height of the Viking Age, Anglo-Saxons also recorded laws about beekeeping, so at least some Scandinavians would known about beekeeping for honey. Carolingian charters at the same time record that land tenants might owe their lord beeswax, which could be especially important if your lord was a bishop or abbot who needed wax candles for his church. All in all, the evidence I know of is very fragmentary, but there's enough to suggest that Viking Age Scandinavians knew about and practiced beekeeping for honey, mead production, and possibly even export (how else would Icelanders have known about mead?).

That said, I haven't found any specific sources about it, keeping in mind that beekeeping would leave few if any identifiable archaeological traces. The wiki page you link to cites a K-10 teacher resource page (sadly of dubious value), a reenactor page (usually high quality, but often as in this case lacking citations and thus unverifiable), and Gareth William's Vikings, which I don't have on hand to reference. It's a great volume (although a bit hyper-focused on elite warrior males), so you might want to grab it from your library or even buy it for yourself to have a look. However, the notes I have from the volume don't include anything about honey, and the reenactor page only mentions honey in Anglo-Saxon and Rus' contexts (i.e. not specifically in Scandinavia), so there might just not be enough evidence surviving to answer the questions you ask for.
