質問 # 19
Which two statements accurately describe the role of hashing in VPNs? (Choose two.)
正解：C、D
解説：
The correct answers are B and D. In VPN cryptography, hashing is used for authentication and integrity checking, not confidentiality. Juniper's IPsec documentation describes MD5 as producing a 128-bit hash, also called a digital signature or message digest, from a message of arbitrary length. It also describes SHA as producing a 160-bit hash from a message of arbitrary length. That directly supports option B because a hash function takes variable-length input and produces a fixed-size digest.
Option D is also correct because Juniper states that the resulting hash is used like a fingerprint of the input to verify content and source authenticity and integrity. Juniper's IPsec overview further explains that Junos compares the calculated message digest against the expected digest to verify that the message has not been tampered with.
Option A is wrong because hashing is not compression; it is one-way digest generation. Option C is wrong because encryption protects confidentiality, while hashing validates integrity and authenticity. In IPsec, algorithms such as AES, DES, and 3DES provide encryption, while MD5, SHA-1, and SHA-2 provide hashing/HMAC-based authentication. Reference topics: IPsec VPN, hashing, HMAC, MD5, SHA, message digest, data integrity.
質問 # 20
A client has attempted communication with a known command-and-control server and it has reached the configured threat level threshold.
Which feed will the clients IP address be automatically added to in this situation?
正解：D
解説：
Infected hosts are internal hosts that have been compromised by malware and are communicating with external C&C servers3. Juniper ATP Cloud provides infected host feeds that list internal IP addresses or subnets of infected hosts along with a threat level3. Once the Juniper ATP Cloud global threshold for an infected host is met, that host is added to the infected host feed and assigned a threat level of 10 by the cloud4. You can also configure your SRX Series device to block traffic from these IP addresses using security policies4.
質問 # 21
While working on an SRX firewall, you execute the show security policies policy-name <name> detail command.
Which function does this command accomplish?
正解：A
解説：
The function that the show security policies policy-name <name> detail command accomplishes is showing policy counters for a configured policy. Policy counters are statistics that indicate how many times a policy has been matched by traffic and what actions have been taken by the policy. Policy counters can help you monitor and troubleshoot the performance and effectiveness of your security policies. The show security policies policy-name <name> detail command displays detailed information about a specific policy, such as its source zone, destination zone, description, state, hit count, byte count, packet count, action count, and session count.

質問 # 22
You are asked to implement IPS on your SRX Series device.
In this scenario, which two tasks must be completed before a configuration will work? (Choose two.)
正解：B、D
解説：
The two tasks that must be completed before a configuration for IPS on an SRX Series device will work are downloading the IPS signature database and installing the IPS signature database. The Security, Specialist (JNCIS-SEC) Study guide provides further information on how to download and install the IPS signature database. Enrolling the SRX Series device with Juniper ATP Cloud is not necessary to make a configuration work, and rebooting the SRX Series device is not required either.
質問 # 23
You are asked to use Junos Space Security Director to download the latest application signatures in the AppID database.
In this scenario, which two statements are correct? (Choose two.)
正解：A、B
解説：
The correct answers are A and B. In Security Director-managed environments, Security Director can download the signature database and then install the active signature database update on selected managed devices. Juniper's Security Director workflow states that after the signature database is downloaded, you install the active database, select the target devices, and Security Director sends the full or incremental signature database update to those devices. That confirms that Security Director stores and manages the signature database package centrally for deployment.
Option B is also correct because the SRX Series device must have the application signature database installed locally for AppID/AppSecure features such as AppFW, AppTrack, AppQoS, and IDP application matching.
Juniper's AppID documentation states that the application package is installed in the application signature database on the device, and that AppID signature updates enable AppSecure features on the SRX.
Option C is wrong because Juniper provides and maintains the predefined AppID database through Juniper's security download infrastructure, not a third-party host. Juniper explicitly describes the predefined application identification database as provided by Juniper Networks and updated through a subscription service. Option D is wrong because a local storage server can be used only as part of an offline/manual update workflow; it is not where the AppID database normally resides. Reference topics: Security Director, AppID database, application signatures, SRX AppSecure services, signature database installation.
