Refer to the exhibit. Which change allows the code to configure VLAN 10 in the Cisco UCS? `` 1 from ucsmsdk.ucshandle import UcsHandle 2 from ucsmsdk.mometa.fabric.FabricVlan import FabricVlan 3 4…

Question

1 from ucsmsdk.ucshandle import UcsHandle
2 from ucsmsdk.mometa.fabric.FabricVlan import FabricVlan
3 
4 handle = UcsHandle("corpucsm.example.com", "admin", "MySecretPassword")
5 handle.login()
6 
7 fabric_lan_dn = handle.query_dn("fabric/lan")
8 newvlan = FabricVlan(parent_mo_or_dn=fabric_lan_dn,
9 name="vlan10",
10 id="10")
11 
12 handle.add_mo(newvlan)
13 
14 handle.logout()

Options

• ALines 8 and 9 should have a line continuation \ at the end.
• BLine 13 should include handle.commit().
• CLine 4 should include transport 443 option.
• DLine 3 should add an import for query_dn.

• A
  8% (5)
• B
  74% (49)
• C
  15% (10)
• D
  3% (2)

Explanation

Option B is correct because ucsmsdk uses a transactional model: handle.add_mo() stages the managed object locally in a pending transaction buffer, but changes are never sent to the UCS Manager until handle.commit() is explicitly called - omitting it means VLAN 10 is queued but never applied.

Why the distractors are wrong:

• A is wrong because line continuation \ is unnecessary - the FabricVlan(...) call is already inside parentheses, making the multi-line syntax valid Python without \.
• C is wrong because port 443 is UCS Manager's default HTTPS port and the connection already works (login succeeds); the transport isn't the issue blocking VLAN creation.
• D is wrong because query_dn is an instance method on UcsHandle, not a standalone importable function - handle.query_dn() is available as-is.

Memory tip: Think of ucsmsdk like a database transaction - add_mo() is INSERT into a staging buffer, and commit() is COMMIT to the actual database. No commit = no change.
