QUESTION 74
You want to enable inter-tenant communicaon with tenant system.
In this Scenario, which two solutions will accomplish this task?

interconnect EVPN switch

interconnect VPLS switch

external router

logical tunnel interface

To enable inter-tenant communication with tenant system, you need to use an external router or a logical tunnel interface.
The other options are incorrect because:
A) Interconnecting EVPN switch is not a valid solution for inter-tenant communication with tenant system.
EVPN (Ethernet VPN) is a technology that provides layer 2 connectivity over an IP network. It can be used to connect different logical systems on the same device, but not tenant systems. Tenant systems are isolated from each other and do not share the same layer 2 domain1.
B) Interconnecting VPLS switch is also not a valid solution for inter-tenant communication with tenant system. VPLS (Virtual Private LAN Service) is another technology that provides layer 2 connectivity over an IP network. It can also be used to connect different logical systems on the same device, but not tenant systems. Tenant systems are isolated from each other and do not share the same layer 2 domain1.
Therefore, the correct answer is C and D. You need to use an external router or a logical tunnel interface to enable inter-tenant communication with tenant system.
To do so, you need to perform the following steps:
For external router, you need to connect the external router to the interfaces of the tenant systems that you want to communicate with. You also need to configure the routing protocols and policies on the external router and the tenant systems to exchange routes and traffic. The external router acts as a gateway between the tenant systems and provides layer 3 connectivity2.
For logical tunnel interface, you need to create a logical tunnel interface on the device and assign it to a tenant system. You also need to configure the IP address and routing protocols on the logical tunnel interface and the tenant systems that you want to communicate with. The logical tunnel interface acts as a virtual link between the tenant systems and provides layer 3 connectivity3.

The 3uspiciou3_Endpoint3 feed is usable by any SRX Series device that is a part of the same realm as SRX-1

Juniper ATP Cloud automatically creates the 3uopi’cioua_Endpoints feed after you commit the security policy.

QUESTION 77
Which three statements about persistent NAT are correct? (Choose Three)

New sessions can only be initiated from a source towards the reflexive address.

New sessions can be initiated from a destination towards the reflexive address.

Persistent NAT only applies to source NAT.

All requests from an internal address are mapped to the same reflexive address.

Persistent NAT applies to both destination and source NAT.

QUESTION 78
Referring to the exhibit,

Which statement about TLS 1.2 traffic is correct?

TLS 1.2 traffic will be sent to routing instance R1 but not forwarded to the next hop.

TLS 1.2 traffic will be sent to routing instance R1 and forwarded to next hop 10.1.0.1.

TLS 1.2 traffic will be sent to routing instance R2 but not forwarded to the next hop.

TLS 1.2 traffic will be sent to routing instance R2 and forwarded to next hop 10.2.0.1.
