質問 # 50
In case of Correction, where is information about Owner stored?
- A. In Connection table of Target Appliances
- B. In Correction tables of all Appliances participating in Correction Layer flow
- C. In Correction table of Target Appliance
- D. In Connection tables of all Appliances participating in Correction Layer flow
正解：B
解説：
Explanation
The Correction Layer is a mechanism that handles asymmetric connections in systems with several cluster members. It allows traffic flow to be handled by a single cluster member, even if the flow is asymmetric1 The Correction Layer works as follows:
*When a packet arrives at a cluster member, it checks if it is the owner of the connection. If yes, it processes the packet normally. If not, it checks the Correction table to find the owner of the connection.
*If the owner is found in the Correction table, the packet is forwarded to the owner with a Correction Layer header. The owner then processes the packet and removes the Correction Layer header before sending it to the destination.
*If the owner is not found in the Correction table, the packet is forwarded to the Maestro Orchestrator (MHO) with a Correction Layer header. The MHO then checks its own Correction table to find the owner of the connection. If the owner is found, the MHO forwards the packet to the owner with a Correction Layer header.
If the owner is not found, the MHO drops the packet and sends an ICMP error message to the source.
*The Correction tables are updated by the MHO whenever a new connection is established or an existing connection is terminated. The MHO sends Correction Layer messages to all clustermembers to inform them about the owner of each connection2
質問 # 51
What cannot be a reason for "Failed to get remote orchestrator interfaces" error message, when clicking on
"Orchestrator" in WebUI
- A. Single orchestrator environment, but configured Orchestrator amount is 2
- B. One orchestrator only, but Orchestrator amount is 2 or no Sync in between orchestrators
- C. Remote orchestrator has no empty interfaces
- D. No Sync between orchestrators
正解：C
解説：
Explanation
One of the possible reasons for the "Failed to get remote orchestrator interfaces" error message, when clicking on "Orchestrator" in WebUI, is that the remote orchestrator has no empty interfaces that can be assigned to a security group. This can happen if all the interfaces on the remote orchestrator are already part of configured security groups, or if the remote orchestrator has no physical interfaces at all. In this case, the WebUI cannot display the unassigned interfaces of the remote orchestrator, and shows the error message.

質問 # 56
How does HyperSync work in a Dual Site environment?
- A. Each active connection has a local backup (on the local site) and a second backup connection on each of the MHOs.
- B. Each active connection has a backup connection on the second site (remote site.)
- C. Each active connection has two local backups (on the local site) and a third backup connection on the second site (remote site.)
- D. Each active connection has a local backup (on the local site) and a second backup connection on the second site (remote site.)
正解：D
解説：
Explanation
HyperSync is a feature of Maestro that enables stateful synchronization of connections and resources across different sites in a Dual Site environment. HyperSync works by creating two backup connections for each active connection: one on the same site as the active connection, and another on the remote site. This ensures that the connection can be seamlessly resumed in case of a failover event, either within the same site or across the sites. HyperSync uses the Site-Sync port and VLANs to transmit the synchronization packets between the Security Group Members and the Maestro Orchestrators.
