• B: Chassis cluster member devices synchronize configuration using the control link. The control link is used to exchange control messages and configuration information between the two nodes of a chassis cluster1. The primary node pushes the configuration to the secondary node and ensures that both nodes have the same configuration2.
• C: A control link failure causes the secondary cluster node to be disabled. If the control link fails, the primary node cannot communicate with the secondary node and assumes that the secondary node is down1. The primary node then disables the secondary node and takes over all the traffic processing2.
• E: Heartbeat messages verify that the chassis cluster control link is working. The control link also carries heartbeat messages that are exchanged between the two nodes every 500 milliseconds by default1. The heartbeat messages indicate the status and health of the nodes and the control link2.
• A: Chassis cluster control links must be configured using RFC 1918 IP addresses. This is a false statement. The control link can use any IP address range as long as it is not in conflict with other interfaces or routes on the cluster nodes1. RFC 1918 IP addresses are private addresses that are not routable on the Internet4.
• D: Recovery from a control link failure requires that the secondary member device be rebooted. This is also a false statement. Recovery from a control link failure does not require rebooting the secondary node1. The secondary node can rejoin the cluster when the control link is restored and the configuration is synchronized2.

The vSRX is a virtual firewall that offers the same features as the physical SRX Series firewalls, but in a virtualized form factor. It supports next-generation firewall (NGFW) capabilities, networking, and automated lifecycle management. It also integrates with cloud orchestration tools and software-defined networking (SDN) solutions1

The vSRX supports VMXNET3 vNICs, which are optimized for performance in virtualized environments. VMXNET3 vNICs offer enhanced networking features such as jumbo frames, hardware offloads, and multicast filtering2

The vSRX runs on Linux as the base OS, which provides a stable and secure platform for the Junos OS and the firewall functionality. Linux also enables the vSRX to leverage the native hypervisor drivers and APIs for better performance and compatibility3

 This is because the error message indicates that the client device does not trust the certificate authority that issued the certificate for the external server. Therefore, you need to import the root CA certificate from the SRX Series device to the client device and add it to the trusted certificate store. This will allow the client device to verify the identity of the SRX Series device and accept the certificates it generates for the external servers3.

The other options are not correct because:

• A. Load a known good, but expired. CA certificate onto the SRX Series device. This will not solve the problem because the client device will still reject the certificates from the SRX Series device if they are signed by an expired CA certificate. The expiration date of the CA certificate is one of the factors that the client device checks when validating the certificate2.
• B. Install a new SRX Series device to act as the client proxy. This will not solve the problem because the new SRX Series device will still need to have a root CA certificate configured and imported to the client devices. The problem is not with the SRX Series device itself, but with the trust relationship between the SRX Series device and the client devices2.
• C. Reboot the SRX Series device. This will not solve the problem because rebooting the SRX Series device will not change the configuration or the certificates on the SRX Series device or the client devices. The problem is not caused by a temporary glitch or a malfunction, but by a mismatch between the certificates on the SRX Series device and the client devices2.

I hope this helps you understand the problem and the solution better. If you want to learn more about SSL client protection proxy, you can check out the following references:
