What is a common cause of IDP database update failures?

Insufficient disk space on the device

The security policy is too restrictive

The device is not connected to the network

A security administrator needs to detect a proprietary application that sends a fixed 12-byte binary header followed by a 4-byte length field, then a payload. The signature must match only when the length field value equals the actual payload length. The administrator creates a custom attack object. Which signature configuration is required?

A stateful signature that uses a context to capture the length field and a condition to compare it against the payload length

A stateless signature with a regular expression that matches the header and a wildcard for the length field

An anomaly attack object that flags any traffic with a 12-byte header followed by a 4-byte length field

A compound attack object that combines two stateless signatures, one for the header and one for the length field

What is a key difference between stateful and stateless signatures?

Stateless signatures are more accurate than stateful signatures

Stateless signatures require more memory than stateful signatures

Stateful signatures track connection state, while stateless signatures do not

Stateful signatures are only used for TCP traffic

When would a stateless signature be preferred over a stateful signature?

When the attack pattern is contained within a single packet

When the device has limited memory

When the attack spans multiple packets in a session

What is a characteristic of compound attack objects?

They detect anomalies in network traffic

They are based on a single signature

They combine multiple attack objects to detect complex attacks

They are automatically generated by the system

IDP Database Management JN0-336 Practice Questions (Page 1)

Part of the Intrusion Detection and Prevention (IDP) domain, which makes up ~10% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 32 practice questions to prepare you well beyond it.
