Refer to the exhibit.
Which statement about the exhibit is true?
A. OTV does not extend STP across sites. Each site runs its own STP, rather than including all sites in a large STP domain. This topology also allows the use of different STP modes, such as PVRST+ or MST, in each site.
B. OTV extends STP across sites. Each site runs its own STP, which includes all sites in a large STP domain. This topology also allows the use of different STP modes, such as PVRST+ or MST in each site.
C. OTV does not extend STP across sites. Each site runs multiple STPs that include all sites in a large STP domain. This topology also allows the use of different STP modes, such as PerPVRST+ or MST, in each site.
D. OTV extends STP across sites. Each site runs its own STP, which includes all sites in a large STP domain. This topology does not allow the use of different STP modes, such as PVRST+ or MST, in each site.
