Question #:1 - [Network Address Translation]
Which statement is correct about source NAT?
It translates MAC addresses to private IP addresses.
It translates private IP addresses to public IP addresses.
It performs bidirectional IP address translation.
It performs translation on ingress traffic only.
Answer: B
Explanation
Source NAT (Network Address Translation) is used on SRX devices to allow hosts with private IP addresses 
to access external networks, such as the Internet. The SRX translates theprivate IP address of the source 
before forwarding traffic toward the destination.host into a public IP address
It does not translate MAC addresses (Option A).
NAT is unidirectional in this case: it specifically translates private-to-public in the outbound direction, 
while the reverse (return traffic) is handled automatically through the session table. It is not a 
bidirectional translation (Option C).
NAT processing occurs as part of the flow module, not limited only to ingress traffic (Option D).
Therefore, the correct statement is that source NAT translates .private IP addresses to public IP addresses

The NGWF feature requires a license.
The NGWF feature consults your local lists before consulting the Juniper cloud.
The NGWF feature does not require a license.
Answer: B C
Explanation
License Requirement (Option B):NextGen Web Filtering (NGWF) is a licensed feature on SRX 
devices. Without a license, the service cannot operate.
Local vs. Cloud Lists (Option C):NGWF checks . If the URL does not local block/allow lists first
match locally, the request is then checked against the Juniper cloud database.
Option A:Incorrect, since the cloud is only consulted if the URL is not in the local list.
Option D:Incorrect, as NGWF requires a valid subscription/license.
Correct Statements:NGWF requires a license, and it checks local lists before cloud lookup.

Question #:3 - [SRX Series Service Gateways]
When traffic enters an interface, which two results does a route lookup determine? (Choose two.)
ingress interface
egress interface
DNS name
egress security zone
Answer: B D
Explanation
When a packet enters an SRX interface, a is performed:route lookup
It determines the (Option B) by checking the destination IP against the routing table.egress interface
Once the egress interface is known, its associated (Option D) is also determined.egress security zone
The is already known when the packet arrives, so the route lookup does ingress interface (Option A)
not determine it.

Question #:4 - [Monitoring and Troubleshooting]
You are troubleshooting first path traffic not passing through an SRX Series Firewall. You have determined 
that the traffic is ingressing and egressing the correct interfaces using a route lookup.
In this scenario, what is the next step in troubleshooting why the device may be dropping the traffic?
Verify that the interfaces are in the correct security zones.
Verify the routing protocol being used.
Verify that source NAT is occurring.
Verify that the correct ALG is being used.
Answer: A
Explanation
After confirming correct routing:
The next step is to . If interfaces are not correctly verify security zone assignments (Option A)
assigned to zones, traffic will not be evaluated against proper inter-zone or intra-zone security policies, 
causing drops.
Option B:The routing protocol is irrelevant once the correct route lookup is confirmed.
Option C:NAT is checked later in the flow, not the immediate next step after routing.
Option D:ALG is only needed for specific applications (FTP, SIP), not general troubleshooting.
Correct Next Step:Verify that interfaces are assigned to the correct security zones.

next-policy
deny
reject
Answer: D
Explanation
Security policies on SRX support several actions:
Permit:Allows traffic to pass according to the rule.
Deny:Silently drops the traffic without notifying the source.
Reject:Drops the trafficand sends a TCP RST (for TCP) or ICMP unreachable (for UDP/other 
back to the source. This provides feedback to the sending host.protocols)
Next-policy:Allows policy chaining to evaluate the next policy set.
Therefore, the action that causes traffic to drop and a message to be sent to the source is .reject
Reference:Juniper Networks –Security Policy Actions, Junos OS Security Fundamentals.
Question #:6 - [Content Security]
What are two ways that an SRX Series device identifies content? (Choose two.)
It identifies and inspects the file extension of each file.
It uses AppID.
It identifies file types in HTTP, FTP, and e-mail protocols.
It uses ALGs.
Answer: B C
Explanation
SRX Series devices provide features that rely on advanced identification mechanisms. File content security
identification is not based merely on file extensions (which can be easily spoofed), but instead ondeep 
:inspection techniques
AppID (Application Identification):AppID is part of the AppSecure suite, allowing the device to 
classify applications and content regardless of port or protocol. This enables the SRX to detect 
applications and their related content for enforcement.

Protocol-based file type identification:The SRX can recognize and identify file types embedded 
within . This providesaccurate content HTTP, FTP, and e-mail (SMTP, IMAP, POP3) protocols
inspection and filtering, independent of file naming conventions.
Why not the others?
File extensions (Option A) are not reliable for content security, so SRX does not use them.
ALGs (Option D) are used forprotocol handling, such as SIP or FTP control channels, not for 
content identification.
Reference:Juniper Networks –Content Security and AppSecure Overview, Junos OS Security Fundamentals, 
Official Course Guide.
Question #:7 - [SRX Series Service Gateways]
When a new traffic flow enters an SRX Series device, in which order are these processes performed?
screens # security policies # zones # routes
screens # routes # zones # security policies
routes # zones # screens # security policies
screens # zones # security policies # routes
Answer: B
Explanation
The packet flow for on SRX is processed in a defined order:new traffic
Screens (Option B, Step 1):Packets are first checked by screens for anomalies such as floods, 
malformed packets, or protocol violations.
Route Lookup (Step 2):The destination IP is checked in the routing table to determine the egress 
interface.
Zone Determination (Step 3):Once the ingress and egress interfaces are known, their associated zones 
are identified.
Security Policies (Step 4):With both zones determined, the packet is evaluated against the configured 
security policies.
Other options list incorrect sequences, either moving routing later or placing policies before zone 
determination, which is not possible.
Correct Processing Order:screens # routes # zones # security policies

Question #:8 - [Content Security]
You want to enable NextGen Web Filtering in SRX Series devices.
In this scenario, which two actions will accomplish this task? (Choose two.)
Generate a CA-signed certificate.
Generate a self-signed certificate.
Configure an SSL initiation profile.
Configure an SSL proxy profile.
Answer: B D
Explanation
NextGen Web Filtering (NGWF) requires SSL proxy functionality to inspect HTTPS traffic. To enable 
NGWF:
Option B:You can generate a for SSL proxy functionality (or import a CA-signed self-signed certificate
certificate, but the course emphasizes self-signed for lab/demo purposes).
Option D:You must configure an so that HTTPS traffic can be decrypted and SSL proxy profile
inspected.
Option A:A CA-signed certificate may be used in production but is not strictly required to enable 
NGWF.
Option C:SSL initiation profiles are used for outbound SSL inspection initiated by the SRX, not for 
NGWF traffic interception.
Correct Actions:Generate a self-signed certificate, Configure an SSL proxy profile
Reference:Juniper Networks –NextGen Web Filtering Configuration with SSL Proxy, Junos OS Security 
Fundamentals.
Question #:9 - [Security Policies]
Which two statements are correct about unified security policies on SRX Series Firewalls? (Choose two.)
Unified security policies match applications before processing policy statements.
Unified security policies can be zone-based or global.
Unified security policies use the application identification (AppID) engine.

Unified security policies with multiple matches use the most restrictive match.
Answer: B C
Explanation
Unified security policies integrate with . Their traditional zone-based policies application-based policies
characteristics include:
Zone-based or global (Option B):Unified policies can be applied as either zone-specific or global 
policies.
AppID engine (Option C):They leverage the AppID engine for application identification, enabling 
fine-grained control at the application layer.
Policy matching (Option A):Policies are evaluated sequentially like standard security policies; 
applications are not matched before policy processing.
Multiple matches (Option D):If multiple policies could match, the first match applies (sequential 
order), not the “most restrictive.”
Correct Statements:B and C
Reference:Juniper Networks –Unified Security Policies and AppSecure Integration, Junos OS Security 
Fundamentals.
Question #:10 - [Security Policies]
You have created a series of security policies permitting access to a variety of services. You now want to 
create a policy that blocks access to all other services for all user groups.
What should you create in this scenario?
global security policy
Juniper ATP policy
IDP policy
integrated user firewall policy
Answer: A
Explanation
To enforce a after other specific policies, the correct solution is acatch-all blocking policy global security 
.policy (Option A)
Juniper - JN0-232Pass Exam
8 of 8Verified Solution - 100% Result
Global policiescan apply universally across zones, and an administrator can configure a final “deny all” 
rule to block any unmatched traffic.
ATP policy (Option B):Protects against advanced threats, not used for catch-all rule enforcement.
IDP policy (Option C):Focuses on intrusion detection and prevention signatures, not general traffic 
blocking.
Integrated user firewall policy (Option D):Applies policies based on user identity, but it does not 
provide a universal block across all services.
Correct Solution:Global security policy
