Authentic Juniper Certification Exam JN0-336 Questions Answers

The correct answer is B. Add custom-attack Custom-FTP-Attack to the attacks section and change the action to drop-packet. In the exhibit, the IDP rule is built under rulebase-ips with a match block and a then block. Attack objects belong inside the match attacks hierarchy because they define what malicious pattern the IDP rule is trying to detect. Juniper’s IDP documentation states that attack objects are specified in rules to identify malicious activity and that the rule’s attack objects/groups are the attacks the device matches in monitored traffic.

The enforcement behavior belongs in the then action hierarchy. The current rule uses close-client; to meet the requirement, it must be changed to drop-packet. Juniper defines Drop Packet as an IDP action that drops a matching packet before it reaches its destination without closing the connection. Option A keeps the wrong action. Option C is structurally wrong because a custom attack object is not configured under the action section. Option D is also wrong because the notification section controls logging/alert behavior, not attack matching. Reference topics: IDP rulebase, custom attack objects, match attacks hierarchy, IDP actions, drop-packet behavior.

The correct answer is C. Enable connectivity between the SRX Series device and Juniper ATP Cloud. Juniper ATP Cloud cannot inspect files, receive verdicts, or apply cloud-based malware intelligence until the SRX is enrolled and has a working secure connection to the ATP Cloud service. Juniper states that SRX enrollment establishes a secure connection between the SRX Series Firewall and the Juniper ATP Cloud server, downloads and installs certificate authorities, creates local certificates, enrolls them with the cloud server, and establishes the secure cloud connection.

Option A is not the first required configuration setting because the anti-malware service depends on successful cloud onboarding and connectivity. Option B is premature because firewall/security policies can reference malware inspection only after the device is properly connected and enrolled. Option D is also later in the workflow; anti-malware policies define how files are inspected and what action is taken, but those policies are useless if the SRX cannot communicate with ATP Cloud. Juniper also notes that ATP Cloud requires both the Routing Engine and Packet Forwarding Engine to reach the Internet, and DNS must resolve the cloud URL. Reference topics: ATP Cloud onboarding, SRX enrollment, advanced anti-malware connection, secure cloud connectivity, anti-malware policy deployment.

The correct answers are A, D, and E. In IPsec VPN terminology, DES, 3DES, and AES are encryption algorithms used to provide confidentiality for protected IP traffic. Juniper’s IPsec material identifies AES, DES, and Triple DES/3DES as IPsec encryption standards, while separating them from authentication hash algorithms such as MD5, SHA-1, and SHA-2. This distinction matters heavily in JNCIS-SEC because IPsec proposals contain different cryptographic functions: encryption protects packet confidentiality, while authentication/hash algorithms validate integrity and origin.

Option B, SHA-1, is incorrect because SHA-1 is a hashing/authentication algorithm, not an encryption algorithm. It produces a message digest used for integrity checking and authentication, commonly as an HMAC variant. Option C, MD5, is also incorrect for the same reason: MD5 is a message-digest algorithm used for authentication/integrity, not for encrypting payload data. AES is the modern preferred encryption family because it is cryptographically stronger than DES and 3DES at comparable key strengths, while DES and 3DES remain historically recognized IPsec encryption algorithms. Reference topics: IPsec VPN, IPsec proposals, encryption algorithms, authentication algorithms, DES, 3DES, AES, SHA, and MD5.
