Falkenhayn listens to the General Staff and makes the objective of the 1916 offensives the removal of Russia from the war rather than a battle of attrition centred on Verdun. The German Army seizes St Petersburg in late 1916 and Russia sues for peace.
The exit of Russia from the war is followed by the early defeat of Rumania and the defeat of the Allies at Salonica.
There are many possibly scenarios possible such as the Ottoman Empire seizes the Suez Canal with assistance from the other Central Powers, Northern Italy is invaded by the K.u.K and Italy exits the war.

It's longest plausible war, not shortest (not that a 1916/early 1917 end is anywhere close to shortest possible).
Mmm...have to spell it out. The victory of the Central Powers in the East focuses the war on the Western Front. The German Army with more manpower and improved food supplies from access to the Ukraine the Western Front becomes a more brutal struggle (think multiple Verduns along the line). With the technology available neither side can effect a breakthrough. The stalemate drags into 1919 or beyond and is resolved either by the entry of the USA into the war and the enacting of "Plan 1919" or by the total exhaustion of the combatants leading to possible revolutions.

Hm, problem is though; if you free up the Eastern Front divisions as early as early 1916; the balance of manpower has just swung extremely heavily in favor of Germany (which can lead to breakthroughs). Bear in mind that Austria-Hungary's also freed up a huge portion of its armies, and is still going. You probably also butterflied the Brusilov offensive, so A-H is still a going force. Ottoman Empire also just got a lot of the pressure taken off it. Knocking out Russia early (and before Verdun and the Somme no less) is seriously one of the things which is basically a war-winner for Germany. Germany won't have nearly as many occupation troops in the East either; since barring a really total collapse of Russia, the Ukraine wasn't actually in the cards (the food situation wasn't extremely critical until 1917).
With the technology available? The Mark I tank entered service in August, so if you delay German advancement in the west they might just be ready in time. Okay, they'll never secure a major breakthrough, but they might just put a bit of pressure on the Germans.With the technology available neither side can effect a breakthrough.

If the losses of Verdun and the Somme are avoided then the British and French armies are in much better shape to resist the German Army. If the Allies were facing a larger German Army they would be less tempted to waste their resources on offensives and may go quite defensive. Perhaps the outcome would be both sides using an elastic defence with very limited offensives which were defeated by massive artillery fire. In this case the conflict could go on for a long time until there was a game changer such as the deployment of US forces or Plan 1919. The K.u.K without the Russian front might be able to eventually overcome Italy although it may take a couple of years - it would be a race between the Austro-Hungarian empire falling apart and defeating the Italians. The Ottomans might well decide that a separate peace with the Allies is in their best interest.
In the long run this WW1 scenario turns into a contest of industrial production - England, France and the USA vs Germany. The outcome is the same as OTL.

By Cambrai, Britain lacked sufficient troops to really make use of the breakthroughs provided by tanks.Even the mass tank attack at Cambrai in OTL in Nov 1917, although successful, did not lead to a breakout from the trenches.
One thing that's a real trend on this site is for people to massively overestimate the Central Powers. As I see it, they basically can't win, unless a miracle happens.
