NEW QUESTION # 66
You are asked to establish a hub-and-spoke IPsec VPN using an SRX Series device as the hub. All of the spoke devices are third-party devices.
Which statement is correct in this scenario?
- A. You must statically configure the next-hop tunnel binding table entries for each of the third-party spoke devices.
- B. You must create a policy-based VPN on the hub device when peering with third-party devices.
- C. You must ensure that you are using aggressive mode when incorporating third-party devices as your spokes.
- D. You must always peer using loopback addresses when using non-Junos devices as your spokes.
Answer: A
Explanation:
To ensure compatibility with third-party devices, next-hop tunnel binding must be manually configured, as dynamic protocols may not be universally supported. This ensures proper routing and secure connections. See Juniper IPsec VPN Configuration Guide.
In a hub-and-spoke IPsec VPN configuration where an SRX device serves as the hub and the spokes are third- party devices, special considerations must be taken into account due to the variability in VPN implementations across different vendors.
* Next-Hop Tunnel Binding (Correct: Option B):With third-party devices as spokes, dynamic routing protocols (like NHRP) may not be supported for dynamically learning spoke routes. In such cases, the next-hop tunnel binding tablemust be statically configured for each spoke on the SRX hub to ensure proper routing and VPN communication. This ensures that traffic between the spokes is routed correctly through the hub.
* Incorrect Options:
* Option Ais incorrect because aggressive mode is typically less secure and not recommended for hub-and-spoke topologies, especially with third-party devices.
* Option Cis incorrect because a route-based VPN is usually preferred when peering with third- party devices for flexibility and scalability.
* Option Dis incorrect because using loopback addresses is not a requirement when peering with third-party devices. It is a common practice in certain designs, but it is not mandatory.

NEW QUESTION # 70
Exhibit:
Referring to the exhibit, your company's infrastructure team implemented new printers. To make sure that the policy enforcer pushes the updated Ip address list to the SRX.
Which three actions are required to complete the requirement? (Choose three)
- A. Configure server feed URL as https://172.25.10.254/myprinters.
- B. Configure Security Director to create a C&C feed.
- C. Configure the server feed URL as http://172.25.10.254/myprinters
- D. Configure Security Director to create a dynamic address feed
- E. Create a security policy that uses the dynamic address feed to allow access
Answer: C,D,E
Explanation:
Referring to the exhibit, your company's infrastructure team implemented new printers. To make sure that the policy enforcer pushes the updated IP address list to the SRX, you need to perform the following actions:
A) Configure the server feed URL as http://172.25.10.254/myprinters. The server feed URL is the address of the remote server that provides the custom feed data. You need to configure the server feed URL to match the location of the file that contains the IP addresses of the new printers. In this case, the file name is myprinters and the server IP address is 172.25.10.254, so the server feed URL should be
http://172.25.10.254/myprinters1.
B) Create a security policy that uses the dynamic address feed to allow access. A security policy is a rule that defines the action to be taken for the traffic that matches the specified criteria, such as source and destination addresses, zones, protocols, ports, and applications. You need to create a security policy that uses the dynamic address feed as the source or destination address to allow access to the new printers. A dynamic address feed is a custom feed that contains a group of IP addresses that can be entered manually or imported from external sources. The dynamic address feed can be used in security policies to either deny or allow traffic based on either source or destination IP criteria2.
C) Configure Security Director to create a dynamic address feed. Security Director is a Junos Space application that enables you to create and manage security policies and objects. You need to configure Security Director to create a dynamic address feed that contains the IP addresses of the new printers.
You can create a dynamic address feed by using the local file or the remote file server option. In this case, you should use the remote file server option and specify the server feed URL as
http://172.25.10.254/myprinters3.
The other options are incorrect because:
D) Configuring Security Director to create a C&C feed is not required to complete the requirement. A C&C feed is a security intelligence feed that contains the IP addresses of servers that are used by malware or attackers to communicate with infected hosts. The C&C feed is not related to the new printers or the dynamic address feed.
E) Configuring the server feed URL as https://172.25.10.254/myprinters is not required to complete the requirement. The server feed URL can use either the HTTP or the HTTPS protocol, depending on the configuration of the remote server. In this case, the exhibit shows that the remote server is using the HTTP protocol, so the server feed URL should use the same protocol1.

NEW QUESTION # 73
What are three core components for enabling advanced policy-based routing? (Choose three.)
- A. Policies
- B. Filter-based forwarding
- C. Routing instance
- D. Routing options
- E. APBR profile
Answer: B,C,E
Explanation:
To enable Advanced Policy-Based Routing (APBR) on SRX Series devices, three key components are necessary: filter-based forwarding, routing instances, and APBR profiles. Filter-based forwarding is utilized to direct specific traffic flows to a routing instance based on criteria set by a policy. Routing instances allow the traffic to be managed independently of the main routing table, and APBR profiles define how and when traffic should be forwarded. These elements ensure that APBR is flexible and tailored to the network's requirements. Refer to Juniper's APBR Documentation for more details.
Advanced policy-based routing (APBR) in Juniper's SRX devices allows the selection of different paths for traffic based on policies, rather than relying purely on routing tables. To enable APBR, the following core components are required:
* Filter-based Forwarding (Answer A):Filter-based forwarding (FBF) is a technique used to forward traffic based on policies rather than the default routing table. It is essential for enabling APBR, as it helps match traffic based on filters and directs it to specific routes.
Configuration Example:
bash
Copy code
set firewall family inet filter FBF match-term source-address 192.168.1.0/24 set firewall family inet filter FBF then routing-instance custom-routing-instance
* Routing Instance (Answer C):A routing instance is required to define the separate routing table used by APBR. You can create multiple routing instances and assign traffic to these instances based on policies. The traffic will then use the routes defined within the specific routing instance.
Configuration Example:
bash
Copy code
set routing-instances custom-routing-instance instance-type forwarding
set routing-instances custom-routing-instance routing-options static route 0.0.0.0/0 next-hop 10.10.10.1
* APBR Profile (Answer D):The APBR profile defines the rules and policies for advanced policy-based routing. It allows you to set up conditions such as traffic type, source/destination address, and port, and then assign actions such as redirecting traffic to specific routing instances.
Configuration Example:
bash
Copy code
set security forwarding-options advanced-policy-based-routing profile apbr-profile match application http set security forwarding-options advanced-policy-based-routing profile apbr-profile then routing-instance custom-routing-instance Other Components:
* Routing Options (Answer B)are not a core component of APBR, as routing options define the general behavior of the routing table and protocols. However, APBR works by overriding these default routing behaviors using policies.
* Policies (Answer E)are crucial in many network configurations but are not a core component of enabling APBR. APBR specifically relies on profiles rather than standard security policies.
Juniper Security Reference:
* Advanced Policy-Based Routing (APBR): Juniper's APBR is a powerful tool that allows routing based on specific traffic characteristics rather than relying on static routing tables. APBR ensures that specific types of traffic can take alternate paths based on business or network needs. Reference: Juniper Networks APBR Documentation.
NEW QUESTION # 74
You are asked to configure tenant systems.
Which two statements are true in this scenario? (Choose two.)
- A. A tenant system can have only one administrator.
- B. Tenant systems have their own configuration database.
- C. After successful configuration, the changes are merged into the primary database for each tenant system.
- D. You can commit multiple tenant systems at a time.
Answer: B,D
Explanation:
Each tenant system maintains its own configuration database, isolating configurations from others, enhancing security and operational efficiency. Junos OS supports multiple concurrent commit operations across tenant systems. Further details are covered in the Juniper Tenant System Guide.
When configuring tenant systems on an SRX device, the following principles apply:
* Tenant Systems Have Their Own Configuration Database (Answer C): Each tenant system has its own isolated configuration database, ensuring that changes made in one tenant system do not affect others. This allows for multi-tenant environments where different tenants can have independent configurations.
* Commit Multiple Tenant Systems Simultaneously (Answer D): The system allows for multiple tenant systems to be committed at the same time, simplifying management when working with multiple tenants. This is particularly useful in large environments where multiple logical systems or tenants need updates simultaneously.
NEW QUESTION # 75
Which two statements describe the behavior of logical systems? (Choose two.)
- A. Each logical system shares the routing protocol process.
- B. A default routing instance is automatically created for each logical system.
- C. A default routing instance must be manually created for each logical system
- D. Each logical system has a copy of the routing protocol process.
Answer: B,D
