* SSH Access (Option B):Host-inbound-traffic controls traffic destined to the SRX device itself (management/control plane). If host-inbound-traffic is not configured to allow SSH, then SSH access to the firewall is blocked.
* Explicit Zone Configuration (Option D):For user-defined security zones, host-inbound-traffic must be explicitly configured to allow specific services (SSH, ICMP, SNMP, etc.).
* Console Access (Option A):Console access is not controlled by host-inbound-traffic. Console access is always available directly.
* Management Zone (Option C):In the management functional zone, host-inbound-traffic is implicitly allowed for management services, so this is not explicitly required.
Correct Statements:B and D

When two networks use the same private IP address ranges, conflicts occur. The solution is to use address translation techniques on the SRX:
* NAT (Network Address Translation):Translates private IP addresses to another IP range, enabling connectivity between overlapping private networks.
* PAT (Port Address Translation):Extends NAT by allowing multiple private IPs to share one or a few public IPs using different port numbers. This is especially useful when there is a limited pool of public IP addresses.
Other options:
* IDP (Option A):Intrusion Detection and Prevention, unrelated to address overlap.
* BGP (Option C):A routing protocol, but it does not solve overlapping IP addressing problems.
Correct Features:NAT and PAT

NAT rule processing on SRX devices follows a deterministic order:
* Top-to-bottom order (Option C):NAT rules are always evaluated in the order they appear in the configuration, starting at the top.
* First-match wins (Option B):Once a packet matches a NAT rule, processing stops.
* Option A:Incorrect. Not all rules are processed; evaluation stops at the first match.
* Option D:Incorrect. NAT rules are never processed bottom-to-top.
Correct Statements:NAT rule processing stops at the first match, and NAT rules are processed top-to- bottom.

When source NAT uses a pool of addresses from thesame subnet as the egress interface, the firewall must respond to ARP requests for those NAT pool IPs. Without this, upstream devices would not know how to forward traffic destined for those IPs.
* Proxy ARPis required (Option D). It enables the SRX to answer ARP requests on behalf of the NAT pool addresses.
* Static NAT (Option A)is unrelated and maps one-to-one, not required here.
* Dynamic DNS (Option B)has no relation to NAT pools.
* Destination NAT (Option C)applies to inbound translations, not outbound source NAT pools.
Correct Feature:Proxy ARP
Reference:Juniper Networks -Source NAT Pools and Proxy ARP, Junos OS Security Fundamentals.

* Static NAT:Provides a one-to-one bidirectional mapping between internal and external IP addresses.
When configured, the translation automatically applies in both directions (Option A is correct). It does not use Port Address Translation (Option C is incorrect).
* Destination NAT:Allows external clients to access internal resources by translating the destination address. It supportsport forwardingso specific services (e.g., HTTP on port 80) can be forwarded to an internal host (Option D is correct). It does not require equal-sized address ranges (Option B is incorrect).
Correct Characteristics:Static NAT is bidirectional, and Destination NAT supports port forwarding.
