When MEP is enabled and a GSLB delay of 10 seconds is configured, what happens if the MEP connection remains DOWN for that period?

• A. The GSLB services will be marked as DOWN if the MEP connection has been DOWN for 10 seconds.
• B. The MEP will be marked as DOWN if the GSLB service has been DOWN for 10 seconds.
• C. The MEP will be marked as DOWN if the GSLB vServer has been DOWN for 10 seconds.
• D. The GSLB services will be marked as DOWN if the LB server has been DOWN for 10 seconds.

Answer: (A)

When MEP is in use, the GSLB subsystem relies on the MEP connection to determine the health of remote GSLB resources. The GSLB delay acts as a safety timer: it specifies how long the MEP channel must remain down before the GSLB service entries are considered DOWN. So if the MEP connection stays DOWN for 10 seconds, the GSLB services are marked DOWN. This helps avoid flapping from brief outages while ensuring traffic isn’t directed to sites whose health can’t be confirmed. The effect is focused on the GSLB service status; the vServer or individual LB server states aren’t the immediate trigger here. Once the MEP connection recovers, the GSLB services will be re-evaluated and can come back UP based on their health.
