1. What are two supported hypervisors for hosting a vSRX? (Choose two.)

VMware ESXi

Solaris Zones

KVM

Docker

2. You are asked to change when your SRX high availability failover occurs. One network interface is considered more important than others in the high availability configuration. You want to prioritize failover based on the state of that interface.

Which configuration would accomplish this task?

Create a VRRP group configuration that lists the reth’s IP address as the VIP while using each physical interface that make up the reth definition of each SRX HA pair.

Configure IP monitoring of the important interface’s IP address and adjust the heartbeat interval and heartbeat threshold to the shortest settings.

Create a separate redundancy group to isolate the important interface; set the priority of the new redundancy group to 255.

Configure interface monitor inside the redundancy group that contains the important physical interface; adjust the weight associated with the monitored interface to 255.

3. Which three Encapsulating Security Payload protocols do the SRX Series devices support with IPsec? (Choose three.)

DES

RC6

TLS

AES

3DES

4. What are three characteristics of session-based forwarding, compared to packet-based forwarding, on an SRX Series device? (Choose three.)

Session-based forwarding uses stateful packet processing.

Session-based forwarding requires less memory.

Session-based forwarding performs faster processing of existing session.

Session-based forwarding usesstateless packet processing,

Session-based forwarding uses six tuples of information.

5. You have configured source NAT with port address translation. You also need to guarantee that the same IP address is assigned from the source NAT pool to a specific host for multiple concurrent sessions.

Which NAT parameter would meet this requirement?

port block-allocation

port range twin-port

address-persistent

address-pooling paired

6. Click the Exhibit button.

Referring to the exhibit, what will happen if client 172.16.128.50 tries to connect to destination 192.168.150.111 using HTTP?

The client will be denied by policy p2.

The client will be denied by policy p1.

The client will be permitted by policy p2.

The client will be permitted by policy p1.

7. Click the Exhibit button.

Which feature is enabled with destination NAT as shown in the exhibit?

NAT overload

block allocation

port translation

NAT hairprinting

8. Which two statements about security policy actions are true? (Choose two.)

The log action implies an accept action.

The log action requires an additional terminating action.

The countaction implies an accept action.

The count action requires an additional terminating action.

9. Which two statements are true about global security policies? (Choose two.)

Global security policies are evaluated before regular security policies.

Global security policies can be configured to match addresses across multiple zones.

Global security policies can match traffic regardless of security zones.

Global security policies do not support IPv6 traffic.

10. Which statement is true about functional zones?

Functional zones are a collection of regulated transit network segments.

Functional zones provide a means of distinguishing groups of hosts and their resources from oneanother.

Functional zones are used for management.

Functional zones are the building blocks for security policies.

11. You have recently configured an IPsec tunnel between two SRX Series devices. One of the devices is assigned an IP address using DHCP with an IP address that changes frequently. Initial testing indicates that the IPsec tunnel is not working. Troubleshooting has revealed that Phase 1 negotiations are failing.

Which two actions would solve the problem? (Choose two.)

Verify that the device with the IP address assigned by DHCP is the traffic initiator.

Verify that VPN monitoring is enabled.

Verify that the IKE policy is configured for aggressive mode.

Verify that PKI is properly configured.

12. Click the Exhibit button.

Which statement would explain why the IP-monitoring feature is functioning incorrectly?

The global weight value is too large for the configured global threshold.

The secondary IP address shouldbe on a different subnet than the reth IP address.

The secondary IP address is the same as the reth IP address.

The monitored IP address is not on the same subnet as the reth IP address.

13. Click the Exhibit button.

You have configured NAT on your network so that Host A can communicate with Server B. You want to ensure that Host C can initiate communication with Host A using Host A’s reflexive address.

Referring to the exhibit, which parameter should you configure on the SRX Series device to satisfy this requirement?

Configure persistent NAT with thetarget-hostparameter.

Configure persistent NAT with thetarget-host-portparameter.

Configure persistent NAT with theany-remote-hostparameter.

Configurepersistent NAT with theport-overloadingparameter.

14. Which feature is used when you want to permit traffic on an SRX Series device only at specific times?

scheduler

pass-through authentication

ALGs

counters

15. Which two modes are supported during the Phase 1 IKE negotiations used to establish an IPsec tunnel? (Choose two.)

transport mode

aggressive mode

main mode

tunnel mode

16. Which statement describes the function of NAT?

NAT encrypts transit traffic in a tunnel.

NAT detects various attacks on traffic entering a security device.

NAT translates a public address to a private address.

NAT restricts or permits users individually or ina group.

17. Click the Exhibit button.

You are monitoring traffic, on your SRX300 that was configured using the factory default security parameters. You notice that the SRX300 is not blocking traffic between Host A and Host B as expected.

Referring to the exhibit, what is causing this issue?

Host B was not assigned to the Untrust zone.

You have not created address book entries for Host A and Host

The default policy has not been committed.

The default policypermits intrazone traffic within the Trust zone.

18. What is the function of redundancy group 0 in a chassis cluster?

Redundancy group 0 identifies the node controlling the cluster management interface IP addresses.

The primary node for redundancy group 0 identifies the first member node in a chassis cluster.

The primary node for redundancy group 0 determines the interface naming for all chassis cluster nodes.

The node on which redundancy group 0 is primary determineswhich Routing Engine is active in the cluster.

19. Which statement describes the function of screen options?

Screen options encrypt transit traffic in a tunnel.

Screen options protect against various attacks on traffic entering a security device.

Screen options translate a private address to a public address.

Screen options restrict or permit users individually or in a group.

20. You want to protect your SRX Series device from the ping-of-death attack coming from the untrust security zone.

How would you accomplish this task?

Configure thehost-inbound-traffic system-services ping exceptparameter in the untrust security zone.

Configure theapplication trackingparameter in the untrust security zone.

Configure afrom-zone untrust to-zonetrustsecurity policy that blocks ICMP traffic.

21. After an SRX Series device processes the first packet of a session, how are subsequent packets for the same session processed?

They are processed using fast-path processing.

They are forwarded to the control plane for deep packet inspection.

Allpackets are processed in the same manner.

They are queued on the outbound interface until a matching security policy is found.
