QUESTION NO: 10

Your company's network has seen an increase in Facebook-related traffic. You have been askedto restrict the amount of Facebook-related traffic to less than 100 Mbps regardless of congestion.

What are three components used to accomplish this task? (Choose three.)

A. IDP policy B. application traffic control C. application firewall D. security policy E. application signature

QUESTION NO: 12

You have just created a few hundred application firewall rules on an SRX device and applied themto the appropriate firewall polices. However, you are concerned that the SRX device mightbecome overwhelmed with the increased processing required to process traffic through theapplication firewall rules.

Which three actions will help reduce the amount of processing required by the application firewallrules? (Choose three.)

In the network shown in the exhibit, you want to forward traffic from the employees to ISP1 andISP2. You want to forward all Web traffic to ISP1 and all other traffic to ISP2. However, your



configuration is not producing the expected results. Part of the configuration is shown in theexhibit. When you run the show route table isp1 command, you do not see the default route listed.


A. The autonomous system number is incorrect, which is preventing the device from receiving adefault route from ISP1. B. The device is not able to resolve the next-hop. C. The isp1 routing instance is configured with an incorrect instance-type. D. The show route table isp1 command does not display the default route unless you add theexact 0.0.0.0/0 option.

Referring to the exhibit, you notice that filter-based forwarding is not working.

What is the reason for this behavior?

A. The RIB group is configured incorrectly. B. The routing policy is configured incorrectly. C. The routing instance is configured incorrectly. D. The default static routes are configured incorrectly.

Answer: CExplanation: Bydefault, wehave a static route in a routing instancesendingthe default route to172.19.1.2.Wewant to hijack traffic matching a particular filter and send the traffic to a differentnext-hop, 172.18.1.1. Weshouldcreate your rib group by importing FIRST the table belonging toyour virtual router and SECOND the table for the forwarding instancethat has the next-hopspecified.

-- Exhibit --

Referring to the topology shown in the exhibit, which two configuration tasks will allow Host A totelnet to the public IP address associated with Server B? (Choose two.)



A. Configure transparent mode to bypass the NAT processing of Server B's public IP address. B. Configure a stateless filter redirecting local traffic destined to Server B's public IP address. C. Configure a destination NAT rule that matches local traffic destined to Server B's public IPaddress. D. Configure a source NAT rule that matches local traffic destined to Server B's public IP address.

Answer: C,DExplanation: In this scenario wehave a host be accessible on the Internet by one address, but have it betranslated to another address when it initiates connections out to the Internet.So we need tocombine Source and destination NAT.

You must configure two SRX devices to enable bidirectional communications between the twonetworks shown in the exhibit. You have been allocated the 172.16.1.0/24 and 172.16.2.0/24networks to use for this purpose.

Which configuration will accomplish this task?

A. Use an IPsec VPN to connect the two networks and hide the addresses from the Internet. B. Using destination NAT, translate traffic destined to 172.16.1.0/24 to Site1's addresses, andtranslate traffic destined to 172.16.2.0/24 to Site2's addresses. C. Using source NAT, translate traffic from Site1's addresses to 172.16.1.0/24, and translate trafficfrom Site2's addresses to 172.16.2.0/24. D. Using static NAT, translate traffic destined to 172.16.1.0/24 to Site1's addresses, and translate



traffic destined to 172.16.2.0/24 to Site2's addresses.

Answer: DExplanation: To examine bidirectional communication you need multiple packet filters, one for each direction. Reference :http://my.safaribooksonline.com/book/networking/junos/9781449381721/security-policy/troubleshooting_security_policy_and_traf
