Be warned for the nomenclature:

Raspberry Pi 2 Model B V1.1 is Cortext-A7 (armv7, specifically BSM2836)
Raspberry Pi 2 Model B V1.2 is Cortext-A53 (aarch64, specifically BCM2837)

The first is long out of production and various places
that still list 2's "model B" as Cortex-A7 actually ship
the Cortex-A53 variant.

Even:

https://www.raspberrypi.org/products/

links to:

https://www.raspberrypi.org/products/raspberry-pi-2-model-b/

which describes the original Cortex-A7 version. The "Buy Now"
button gives you selections of places selling the Cortex-A53
variant (V1.2) explicitly and others still listing the
Cortex-A7 variant (V1.1) explicitly, despite what some
ship when you order.
