B. Dynamically generating and sending a certificate request to an authorized CA using OCSP.
C. Manually generating a CRL request and submitting that request to an authorized CA.
D. Dynamically generating and sending a certificate request to an authorized CA using SCEP.
Answer: A,D

Q25. Which statement is true about Layer 2 zones when implementing transparent mode security?
A. All interfaces in the zone must be configured with the protocol family mpls.
B. All interfaces in the zone must be configured with the protocol family inet.
C. All interfaces in the zone must be configured with the protocol family bridge.
D. All interfaces in the zone must be configured with the protocol family inet6.
Answer: C

Q26. You are performing AppSecure traffic processing to enforce AppFW.
What happens when traffic matching an established security session is newly detected as a different application?
A. The security processing facility of the data plane re-examines the whitelist or blacklist referenced in the security policy to see if the new application is permitted.
B. The newly detected application will not be permitted and session will be torn down unless a specific match exists against the exempt rulebase.
C. Zone-based firewall rules will be re-parsed to determine if a rule exists that permits the newly detected application.
D. The application will not be permitted if doing so would violate the session limit in the screen properties applied to that zone.
Answer: B
Q27. Which statement is true about NAT?
A. When you implement destination NAT, the router does not apply ALG services.
B. When you implement destination NAT, the router skips source NAT rules for the initiating traffic flow.
C. When you implement static NAT, each packet must go through a route lookup.
D. When you implement static NAT, the router skips destination NAT rules for the initiating traffic flow.
Answer: D
Explanation: The NAT type determines the order in which NAT rules are processed. During the first packet processing for a flow, NAT rules are applied in the following order:
✑ Static NAT rules
✑ Destination NAT rules
✑ Route lookup

Q28. You have recently deployed a dynamic VPN. The remote users are complaining that communications with devices on the same subnet as the SRX device are intermittent and often fail. The tunnel is stable and up, and communications with remote devices on different subnets work without any issues.Which configuration setting would resolve this issue?
A. adding local-redirect at the [edit security nat] hierarchy
B. adding local-redirect at the [edit interfaces <interface-name>] hierarchy
C. adding proxy-arp at the [edit security nat] hierarchy
D. adding proxy-arp at the [edit interfaces <interface-name>] hierarchy
Answer: C

Q29. You have installed a new IPS license on your SRX device and successfully downloaded the attack signature database. However, when you run the command to install the database, the database fails to install.What are two reasons for the failure? (Choose two.)
A. The file system on the SRX device has insufficient free space to install the database.
B. The downloaded signature database is corrupt.
C. The previous version of the database must be uninstalled first.
D. The SRX device does not have the high memory option installed.
Answer: A,B
Explanation:
We don’t need to uninstall the previous version to install a new license, as we can update the same. Reference:http://kb.juniper.net/InfoCenter/index?page=content&id=KB16491. Also high memory option is licensed feature.
The only reason for failure is either there is no space left or downloaded file is corrupted due to incomplete download because of internet termination in between. Reference:http://kb.juniper.net/InfoCenter/index?page=content&id=KB23359
Q30. You are asked to deploy dynamic VPNs between the corporate office and remote employees that work from home. The gateway device at the corporate office consists of a pair of SRX650s in a chassis cluster.Which two statements about the deployment are true? (Choose two.)
A. The SRX650s must be separated as standalone devices to support the dynamic VPNs.
B. The remote clients must install client software to establish a tunnel with the corporate network.
C. The remote clients must reside behind an SRX device configured as the local tunnel endpoint.
D. The SRX650 must have HTTP or HTTPS enabled to aid in the client software distribution process.
