NEW QUESTION 1
Your IPsec tunnel is configured with multiple security associations (SAs). Your SRX Series device supports the CoS-based IPsec VPNs with multiple IPsec SAs feature. You are asked to configure CoS for this tunnel. Which two statements are true in this scenario? (Choose two.)
A. The local and remote gateways do not need the forwarding classes to be defined in the same order.
B. A maximum of four forwarding classes can be configured for a VPN with the multi-sa forwarding- classes statement.
C. The local and remote gateways must have the forwarding classes defined in the same order.
D. A maximum of eight forwarding classes can be configured for a VPN with the multi-sa forwarding- classes statement.
Answer: AD
NEW QUESTION 2
You have deployed automated threat mitigation using Security Director with Policy Enforcer, Juniper ATP Cloud, SRX Series devices, Forescout, and third-party switches. In this scenario, which device is responsible for communicating directly to the third-party switches when infected hosts need to be blocked?
A. Forescout
B. Policy Enforcer
C. Juniper ATP Cloud
D. SRX Series Device
Answer: B
Explanation:
Policy Enforcer receives these policies and translates them into device-specific commands. It then communicates with the third-party switches (using protocols like SNMP, RADIUS, or vendor-specific APIs) to enforce those commands, such as blocking the infected hosts’ MAC addresses or port access:
– Centralized Enforcement: Policy Enforcer acts as the central point of enforcement for Security Director policies, ensuring consistent security across the network. Multi-Vendor Support: It can interact with a wide range of network devices, including switches from different vendors.
– Automation: Policy Enforcer automates the policy enforcement process, enabling rapid response to threats.
NEW QUESTION 3
You want to create a connection for communication between tenant systems without using physical revenue ports on the SRX Series device. What are two ways to accomplish this task? (Choose two.)
A. Use an external router.
B. Use an interconnect VPLS switch.
C. Use a secure wire.
D. Use a point-to-point logical tunnel.
Answer: BD
NEW QUESTION 4
You have deployed an SRX Series device at your network edge to secure Internet-bound sessions for your local hosts using source NAT. You want to ensure that your users are able to interact with applications on the Internet that require more than one TCP session for the same application session. Which two features would satisfy this requirement? (Choose two.)
A. address persistence
B. STUN
C. persistent NAT
D. double NAT
Answer: AC
Explanation:
Address persistence ensures that the same NAT IP address is used for all sessions originating from a single source IP. Persistent NAT maintains connections for applications needing multiple sessions, like VoIP. For applications that require multiple TCP sessions for the same application session (such as VoIP or certain online games), the SRX device needs to handle NAT properly to maintain session continuity.
NEW QUESTION 5
You want to use a security profile to limit the system resources allocated to user logical systems. In this scenario, which two statements are true? (Choose two.)
A. If nothing is specified for a resource, a default reserved resource is set for a specific logical system.
B. If you do not specify anything for a resource, no resource is reserved for a specific logical system, but the entire system can compete for resources up to the maximum available.
C. One security profile can only be applied to one logical system.
D. One security profile can be applied to multiple logical systems.
Answer: BD
Explanation:
When using security profiles to limit system resources in Juniper logical systems:
– No Resource Specification (Answer B): If a resource limit is not specified for a logical system, no specific amount of system resources is reserved for it. Instead, the logical system competes for resources along with others in the system, up to the maximum available. This allows flexible resource allocation, where logical systems can scale based on actual demand rather than predefined limits.
– Multiple Logical Systems per Security Profile (Answer D): A single security profile can be applied to multiple logical systems. This allows administrators to define resource limits once in a profile and apply it across several logical systems, simplifying management and ensuring consistency across different environments.
These principles ensure efficient and flexible use of system resources within a multi-tenant or multi-logical-system environment.
NEW QUESTION 6
Which two statements are true regarding NAT64? (Choose two.)
A. An SRX Series device should be in packet-based forwarding mode for IPv4.
B. An SRX Series device should be in packet-based forwarding mode for IPv6.
C. An SRX Series device should be in flow-based forwarding mode for IPv4.
D. An SRX Series device should be in flow-based forwarding mode for IPv6.
Answer: BC
NEW QUESTION 7
You have deployed automated threat mitigation using Security Director with Policy Enforcer, Juniper ATP Cloud, SRX Series devices, and EX Series switches. In this scenario, which device is responsible for blocking the infected hosts?
A. Policy Enforcer
B. Security Director
C. Juniper ATP Cloud
D. EX Series Switch
Answer: A
Explanation:
Policy Enforcer interacts with other network elements like EX switches to enforce blocking of infected hosts based on threat intelligence from ATP Cloud and other sources. In a Juniper automated threat mitigation setup involving Security Director, Policy Enforcer, Juniper ATP Cloud, SRX Series, and EX Series switches, the Policy Enforcer is the component responsible for blocking infected hosts.
NEW QUESTION 8
You are asked to see if your persistent NAT binding table is exhausted. Which show command would you use to accomplish this task?
A. show security nat source persistent-nat-table summary
B. show security nat source summary
C. show security nat source pool all
D. show security nat source persistent-nat-table all
Answer: D
Explanation:
The command show security nat source persistent-nat-table all provides a comprehensive view of all entries in the persistent NAT table, enabling administrators to monitor and manage resource exhaustion. In Junos OS, when persistent NAT is configured, a binding table is created to keep track of NAT sessions and ensure that specific hosts are allowed to initiate sessions back to internal hosts. To check if the persistent NAT binding table is full or exhausted, the correct command must display the entire table. The command show security nat source persistent-nat-table all will display the entire persistent NAT binding table. This allows you to check whether the table is exhausted or if there is space available for new persistent NAT sessions.
NEW QUESTION 9
You want to bypass IDP for traffic destined to social media sites using APBR, but it is not working and IDP is dropping the session. What are two reasons for this problem? (Choose two.)
A. IDP disable is not configured on the APBR rule.
B. The application services bypass is not configured on the APBR rule.
C. The APBR rule does a match on the first packet.
D. The session did not properly reclassify midstream to the correct APBR rule.
Answer: AD
NEW QUESTION 10
You are deploying OSPF over IPsec with an SRX Series device and third-party device using GRE. Which two statements are correct? (Choose two.)

B. Sites with overlapping address spaces can be supported.
C. OSPF over GRE over IPsec is required to enable intersite dynamic routing.
D. Sites with overlapping address spaces cannot be supported.
Answer: BC
NEW QUESTION 16
Which two elements are necessary to configure a rule under an APBR profile? (Choose two.)
A. instance type
B. match condition
C. then action
D. RIB group
Answer: BC
Explanation:
Here’s why those elements are necessary for configuring a rule under an APBR profile:
– match condition (Answer B): This defines the criteria for matching traffic to the APBR rule. It can include:
* Applications: Match based on specific applications or application groups.
* URL categories: Match based on URL categories provided by a web filtering service.
* Other criteria: You can also match based on source/destination IP addresses, ports, protocols, etc.
– then action (Answer C): This specifies the action to take when traffic matches the rule. The primary action in APBR is “routing-instance”, this redirects the matching traffic to a specific routing instance, allowing you to steer traffic through different paths based on the application or URL category.
