When deploying a VSX Gateway managed by a Provider-1 MDS, how many Administrators can connect in Read/Write mode to the MDS database simultaneously?

Question

Options

• AOne for each CMA
• BTwo: One can connect to the Management Virtual System database, while the other connects
• COne
• DNo more than 25
• ENo more than 250

• A
  74% (31)
• B
  2% (1)
• C
  7% (3)
• D
  14% (6)
• E
  2% (1)

Explanation

In Provider-1 architecture, each CMA (Customer Management Attachment) maintains its own independent database, and only one administrator can hold a Read/Write lock per CMA at a time - but since an MDS hosts multiple CMAs, the total simultaneous R/W connections scales with the number of CMAs present. This is why A is correct: the limit is "one per CMA," not a single global limit across the entire MDS.

Why the distractors fail:

• B is wrong because there is no special two-slot split between a "Management Virtual System database" and another; the R/W lock model is simply one per CMA.
• C is wrong because it implies a single global R/W slot for the whole MDS, ignoring that each CMA is an isolated management domain with its own independent lock.
• D and E are wrong because Provider-1 imposes no arbitrary numerical cap of 25 or 250; the real constraint is architectural (one R/W lock per CMA database).

Memory tip: Think of each CMA as its own "mini-management server" - just as a standalone SmartCenter allows only one R/W admin at a time, each CMA follows the same rule. Multiply that rule by the number of CMAs and you get the total R/W capacity of the MDS.
