vSRX is a virtual firewall that runs on various cloud platforms, including AWS and OpenStack. AWS is a cloud service provider that offers infrastructure as a service (IaaS) solutions, such as compute, storage, and networking resources. OpenStack is an open source software platform that enables cloud orchestration, which is the automated management of cloud resources and services. vSRX supports both AWS and OpenStack as deployment options, and integrates with their features and tools. For example, vSRX can use cloud-init to automate the initialization of vSRX instances in AWS and OpenStack environments. vSRX can also leverage the security groups and elastic IP addresses of AWS, and the network and security services of OpenStack. References:

Based on the exhibit, Nancy logged in to the juniper.net Active Directory domain, as shown by the domain name in the user identity information. The IP address of the authenticating domain controller is 172.25.11.140, as shown by the domain controller address in the user identity information. The IP address of Nancy’s client PC is not 172.25.11, but 172.25.11.11, as shown by the source IP address in the user identity information. Nancy is not a member of the Active Directory sales group, but of the marketing group, as shown by the group name in the user identity information34 References:

 Logging for a security policy can be configured to generate log entries at session initialization, at session close, or both. Logging at session initialization records the initial packet that matches the policy and triggers the session creation. Logging at session close records the summary statistics of the session, such as bytes and packets transmitted and received, and the reason for session termination. Logging at session initialization and close provides the most complete information about the traffic that matches the policy. Logging at fixed intervals, such as every 10 minutes or every 60 seconds, is not supported by Junos OS security policies. References:

Juniper ATP Cloud is a cloud-based threat detection service that protects all hosts in your network against evolving security threats. It assigns a threat level to each attacker IP address from 1 to 10, with 10 being the highest severity. Once the target threshold ismet, Juniper ATP Cloud continues looking for threats for a configurable duration from 0 to 10 minutes. This allows Juniper ATP Cloud to collect more information about the attacker and the attack vector, and to update the threat intelligence accordingly. The other options are incorrect. Option A is not configurable, and option D is not consistent with the documentation. References:

• A: In the vSwitch security settings, accept promiscuous mode. This is a true statement. Promiscuous mode allows the vSwitch to forward all frames to the vSRX control interface, regardless of the destination MAC address1. This is necessary for the control link to function properly and exchange heartbeat messages between the cluster nodes2.
• C: In the vSwitch security settings, reject forged transmits. This is also a true statement. Forged transmits are frames that have a source MAC address that is different from the one that is assigned to the vNIC by the host operating system1. Rejecting forged transmits prevents spoofing attacks and ensures that the control link traffic is authentic2.
• B: In the vSwitch properties settings, set the VLAN ID to None. This is a false statement. The VLAN ID for the vSwitch can be any value as long as it matches the VLAN ID for the vSRX control interface1. The VLAN ID is used to tag the control link traffic and separate it from other traffic on the same vSwitch2.
• D: In the vSwitch security settings, reject MAC address changes. This is also a false statement. MAC address changes are allowed for the vSRX control interface, as the vSRX uses the MAC address of the control link to identify the cluster nodes1. Rejecting MAC address changes would prevent the cluster formation and synchronization2.
