An ADVPN configuration has been verified on both the hub and spoke devices and it seems fine. However, OSPF is not functioning as expected.
Referring to the exhibit, which two statements under interface st0.0 on both the hub and spoke devices would solve this problem? (Choose two.)

Question Image

A passive
B dynamic-neighbors
C interface-type p2mp
D interface-type p2p

Question 4

Click the Exhibit button.

You have configured a CoS-based VPN that is not functioning correctly.
Referring to the exhibit, which action will solve the problem?

Question Image

A You must change the loss priorities of the forwarding classes to low.
B You must delete one forwarding class.
C You must change the code point for the DB-data forwarding class to 10000.
D You must use inet precedence instead of DSCP.

Question 5

Click the Exhibit button.

Which two statements are correct about the output shown in the exhibit? (Choose two.)

Question Image

A The data shown requires a traceoptions flag of host-traffic.
B The data shown requires a traceoptions flag of basic-datapath.
C The packet is dropped by a configured security policy.
D The packet is dropped by the default security policy.

Question 6

Click the Exhibit button.

Referring to the exhibit, which two statements are correct? (Choose two.)

Question Image

A You cannot secure intra-VLAN traffic with a security policy on this device.
B You can secure inter-VLAN traffic with a security policy on this device.
C The device can pass Layer 2 and Layer 3 traffic at the same time.
D The device cannot pass Layer 2 and Layer 3 traffic at the same time.

Question 7

Click the Exhibit button.

You implement persistent NAT to allow any device on the external side of the firewall to initiate traffic once the initial translation has been established. Communication is not working according to the design requirements.

Referring to the exhibit, which statement is correct?

Question Image

A The any-remote-host parameter does not support interface-based NAT and needs an IP pool to work.
B The target-host parameter should be used instead of the any-remote-host parameter.
C The target-host-port parameter should be used instead of the any-remote-host parameter.
D The port-overloading parameter needs to be turned off in the NAT source interface configuration.

Question 8

What is the advantage of using separate st0 logical units for each spoke connection?

A It enables assignments of different settings to each logical unit.
B It is easy to configure even when managing many st0 units.
C Junos devices can exchange NHTB data automatically using this method.
D It facilitates scalability.

Question 9

What are three core components for enabling advanced policy-based routing? (Choose three.)

A APBR profile
B routing instance
C filter-based forwarding
D policies
E routing options

Question 10

Click to the Exhibit button.

Which two statements are correct about the NAT configuration shown in the exhibit? (Choose two.)

Question Image

A Any external host will be able to initiate a session to the reflexive address.
B The original destination port is used for the source port for the session.
C Only a specific host can initiate a session to the reflexive address after the initial session.
D Only an internal host can initiate a session after translation.

Question 11

Click the Exhibit button.

You are configuring NAT64 on your SRX Series device. You have committed the configuration shown in the exhibit. Unfortunately, the communication with the 10.10.201.10 server is not working. You have verified that the interfaces, security zones, and security policies are all correctly configured.
In this scenario, which action will solve this issue?

Question Image

A Configure destination NAT to translate return traffic from the IPv4 address to the IPv6 address of your source device.
B Configure source NAT to translate return traffic from IPv4 address to the IPv6 address of your source device.
C Configure proxy-ndp on the IPV6 interface for the 2001:db8::1/128 address.
D Configure proxy-arp on the external IPv4 interface for the 10.10.201.10/32 address.

Question 12

Click the Exhibit button.

Referring to the exhibit, which two statements are true? (Choose two.)

Question Image

A Hosts in the Local zone can communicate with hosts in the Trust zone with a security policy.
B Hosts in the Local zone can be enabled for control plane access to the SRX.
C You can configure security policies for traffic flows between hosts in the Local zone.
D An IRB interface is required to enable communication between the Trust and the Untrust zones.

Question 13

Which two statements are correct about DNS doctoring? (Choose two.)

A The DNS ALG must be disabled.
B Proxy ARP is required if your NAT pool for the server is on the same subnet as the uplink interface.
C Proxy ARP is required if your NAT pool for the server is on a different subnet as the uplink interface.
D The DNS ALG must be enabled.

Question 14

You are deploying IPsec VPNs to securely connect several enterprise sites with OSPF for dynamic routing. Some of these sites are secured by third- party devices not running Junos.

Which two statements are true for this deployment? (Choose two.)

A OSPF over IPsec can be used for intersite dynamic routing.
B Sites with overlapping address spaces can be supported.
C OSPF over GRE over IPsec is required to enable intersite dynamic routing.
D Sites with overlapping address spaces cannot be supported.

You are deploying threat remediation to endpoints connected through third-party devices.
In this scenario, which three statements are correct? (Choose three.)
