Which statement correctly describes links and pipes in Cisco Expressway?

Question

Options

• AThe lower bandwidth restriction is applied to calls over a link that is associated to two pipes.
• BA call between two endpoints in the same subzone or zone fails if there is no link between the
• CA maximum of one pipe can be applied to a link.
• DA call between two endpoints in the same subzone or zone fails if there is no pipe between the

• A
  91% (21)
• B
  4% (1)
• D
  4% (1)

Explanation

In Cisco Expressway, a pipe defines a bandwidth limit (maximum bit rate) for calls traversing a logical path. A link connects two zones or subzones and can have up to two pipes associated with it (one per direction or two with different constraints). When a link has two associated pipes, Expressway applies the more restrictive - i.e., the lower - bandwidth limit to calls over that link. This is the conservative, safe behavior to prevent oversubscription. Option B is incorrect because calls between endpoints in the same subzone do NOT require a link; intra-subzone communication is handled by the subzone's own bandwidth settings. Option C is incorrect because up to two pipes can be associated with a single link, not just one. Option D is incorrect for the same reason as B - links are required between different zones/subzones, not within the same one.
