NEW QUESTION # 54
Screens on an SRX Series device protect against which two types of threats? (Choose two.)
- A. zero-day outbreaks
- B. ICMP flooding
- C. malicious e-mail attachments
- D. IP spoofing
Answer: B,D
Explanation:
ICMP flood
Use the ICMP flood IDS option to protect against ICMP flood attacks. An ICMP flood attack typically occurs when ICMP echo requests use all resources in responding, such that valid network traffic can no longer be processed.
The threshold value defines the number of ICMP packets per second (pps) allowed to be send to the same destination address before the device rejects further ICMP packets.
IP spoofing
Use the IP address spoofing IDS option to prevent spoofing attacks. IP spoofing occurs when an invalid source address is inserted in the packet header to make the packet appear to come from a trusted source.

NEW QUESTION # 68
You are asked to configure your SRX Series device to block all traffic from certain countries. The solution must be automatically updated as IP prefixes become allocated to those certain countries.
Which Juniper ATP solution will accomplish this task?
- A. IDP
- B. Geo IP
- C. unified security policies
- D. C&C feed
Answer: B
Explanation:
Juniper ATP Geo IP can help to accomplish this task by using geolocation services to determine the geographical location of IP addresses. As IP prefixes get allocated to the countries that you have specified, the Geo IP solution will automatically update the configured firewall policies to block any traffic that is coming from those specific countries.
This is a great solution for blocking specific countries - as it will allow for a more personalized and targeted approach to firewall policies - and thus, to increase the effectiveness of the solution at blocking potential malicious traffic.

NEW QUESTION # 76
What is the default value of the dead peer detection (DPD) interval for an IPsec VPN tunnel?
- A. 20 seconds
- B. 40 seconds
- C. 10 seconds
- D. 5 seconds
Answer: D
Explanation:
The default value of the dead peer detection (DPD) interval for an IPsec VPN tunnel is 5 seconds. DPD is a mechanism that enables the IPsec device to detect if the peer is still reachable or if the IPsec VPN tunnel is still active. The DPD interval determines how often the IPsec device sends DPD packets to the peer to check the status of the VPN tunnel. A value of 5 seconds is a common default, but the specific value can vary depending on the IPsec device and its configuration.
