Begin to Test:

1. Which of the following options are correct regarding SMC and SC deployment? (Multiple choice)

In large-scale networks, SMC and SC can be deployed in different servers, supporting dual-machine active/standby networking of SMC and SC.

When deploying an active/standby SMCSC network, the two SMCs and SCs need to be set as mutually trusted devices.

In a medium-sized network, SMC and SC are deployed together in the same server as Docker containers, and SMSC active/standby deployment is supported.

In a small network, such as CloudLink Edge 1000, SMC and SC are deployed in the same server as containers, and SMSC master and backup can be implemented based on Docker.

16. In a single-level SMC network, which of the following statements about VDC Client configuration is incorrect?

When configuring the VDC Client monitoring terminal, if the SMC has an external SC and the external SC is enabled, the SC address of the VDC Client monitoring terminal must be set to the address of the external SO.

When logging into the VDC Client, the default login protocol is "Https".

When logging into the VDC client, you need to configure "Server" to "SMC IP address"

Before logging into the VDC Client, you must create a VDC login account on the SMC in advance and the account role must be system administrator.

Question 16 of 33

17. A company received the following suggestions when dividing network security domains. Which of them can be adopted? (Multiple choice)

Deploy devices and business resources with the same security level in the same security zone. Then, assign addresses to devices based on the security zone.

The more security zones there are, the more precise the network access control is and the more secure the network is, but the management complexity will also increase accordingly.

For systems that do not interact with each other, they can be placed in the same subnet to save network resources and reduce management complexity.

For systems with different security levels that need to interact, please deploy them in different security zones and implement strict security policies.

Question 17 of 33

18. Which of the following descriptions of Network Address Translation (NAT) are correct? (Multiple choice)

Dynamic NAT is used for many-to-many mapping of private IP addresses to public IP addresses.

Question 18 of 33

19. If a VP9660 is configured with four media boards (operation slot numbers 2, 3, 8, and 9), which of the following media boards will the system select as the media board by default?

Question 19 of 33

20. Which of the following options are correct regarding the SC active/standby dual-node system?

The master is bound to a virtual IP address for external communication and is responsible for sending synchronization data to the backup machine and sending heartbeats to the backup machine at regular intervals.

The backup SC receives the synchronization data of the host and regularly detects the heartbeat of the host. Once the host heartbeat is not received within a timeout, the master-slave switchover is automatically executed.

SC active/standby switching is divided into manual switching and abnormal switching, which is initiated and executed by the backup SC.

When the backup SC detects an abnormal system operation status, it will notify the host to perform active/standby switching.
