Exam overview 1Z0-404

The Oracle Communications Session Border Controller 7 Basic Implementation Essentials (1Z0-404) certifies an engineer's ability to deploy and operate Oracle's Acme Packet SBC at the network edge. Administered by Oracle as an OPN Certified Specialist exam, it targets professionals who configure session border control for SIP-based voice, video, and messaging traffic across IP borders.

This exam suits network architects, system integrators, support engineers, and configuration implementers who already work with VoIP and TCP/IP. Candidates should be comfortable with routine SBC operations—system access, ACLI configuration, backup and restore—before attempting the test. Hands-on time with the Acme Packet OS configuration tree is the most reliable preparation path.

The blueprint spans eight core topics rather than weighted domains: SIP essentials, SBC fundamentals, initial configuration, interface provisioning, realm and routing concepts, Peering environment setup, Access-Backbone configuration, and High Availability. Practitioner-level items expect you to troubleshoot boot issues, SIP call flows, registration caching, and HA failover using ACLI tools.

For 1Z0-404 candidates, our practice set reproduces the exam's eight topics in proportion—from ACLI boot parameters and realm bridging (PBRB) through Session Agent Group strategies and SIP Hosted NAT Traversal. Every online question ships with a detailed answer explanation that walks the ACLI path and reasoning, while the downloadable PDF packages the full bank for offline review during commutes or lab downtime.

Official Exam Domains & Weighting

The 1Z0-404 exam is organized into eight core topics. Oracle publishes the topic list but not percentage weightings, so candidates should prepare across all eight rather than prioritizing by domain. To pass, you must master the following:

Topic 1: Session Initiation Protocol (SIP) Essentials

Covers SIP architecture elements including proxies and back-to-back user agents (B2BUAs), plus diagnosing a basic SIP call flow processed by the Oracle SBC.

Topic 2: Introduction to Session Border Controller (SBC)

Describes the basic functions of an SBC, the boot process and SBC services, and the device's role at IP network borders.

Topic 3: Initial Configuration

Explains boot parameters and their effects, the configuration tree, user versus super-user ACLI commands, and creating, modifying, and deleting configuration elements.

Topic 4: Provisioning Interfaces

Covers default network interface behavior, provisioning physical and network (VLAN/non-VLAN) interfaces, and enabling management operations through the media interface.

Topic 5: Session Border Controller Concepts

Focuses on realms and realm bridging, global SIP parameters, the Media Manager, SIP interfaces, steering pools, routing policies, session agents, and Header Manipulation Rules (HMRs).

Topic 6: Peering Environment Configuration

Describes Policy-Based Realm Bridging (PBRB) in Peering environments, building a working Peering setup, and configuring Peering access rules.

Topic 7: Access-Backbone Environment Configuration

Explains registration caching, Hosted NAT Traversal (HNT) and Adaptive HNT, the PBRB model in Access-Backbone, and media latching.

Topic 8: Configuring SBC High Availability

Covers the HA mechanism and node states, configuring an HA SBC pair, and managing system failover between primary and secondary nodes.

Sample questions 7 of 64 shown

Q1
Which two functionalities are provided by Session Border Controllers? (Choose two.)
1. they span multiple networks and provide edge proxy functions between them
2. they are session-aware devices that enable control of end-to-end interactive communications across PSTN network borders
3. they enable premium interactive services across IP network borders by complementing existing edge routers
4. they provide routing functions for IP, TCP, and SMTP using application parameters
5. they replace typical edge routers and firewalls in order to provide a unified network border for signaling and media control
Session Border Controllers (SBCs) span multiple networks to deliver edge proxy functions between them and complement existing edge routers to enable premium interactive services across IP network borders. They operate at IP network borders rather than PSTN borders, and they do not replace standard edge firewalls or route SMTP traffic.
Q2
Your Session Border Controller is configured as the source and destination for all signaling messages and media streams coming into and leaving the provider's network. Which two SIP functions does it provide? (Choose two.)
1. an IP edge router
2. Back-to-Back User Agent (B2BUA)
3. Edge proxy
4. Data firewall
5. Media gateway
When acting as the termination and origination point for both signaling and media at the network perimeter, the SBC functions as a Back-to-Back User Agent (B2BUA) and a SIP Edge Proxy.
Q3
How does the SIP registrar server maintain the registered user's information in its database?
1. by querying a DNS server
2. by querying an ENUM server
3. by creating a registration cache entry, which is an association between a layer 3 IP address and the User Agent (UA) Via address
4. by creating a location record, which is an association between the Call-ID and the User Agent (UA) Contact address
5. by creating a binding, which is an association between a globally unique SIP URI and the User Agent (UA) Contact address
A SIP registrar server stores registration state by creating a binding, which maps a user's globally unique SIP Address of Record (AOR) URI to their current User Agent (UA) Contact address.
Q4
You are examining a SIP packet. There is no final response to the ACK method. What is the reason for this?
1. The ACK method was defined only in RFC 2543 and it has been deprecated
2. The ACK method is part of the INVITE transaction
3. The ACK method is an exception in RFC 3261
4. The ACK method is an optional SIP method
5. The ACK method was replaced with the CANCEL method in RFC 3261
Under RFC 3261, the ACK method serves as a confirmation mechanism within the INVITE transaction (or to confirm receipt of a final 2xx response) and does not elicit a SIP response itself.
Q5
Where are passwords and licensing information stored?
1. Non-Volatile Random Access Memory (NVRAM)
2. Content Addressable Memory (CAM)
3. RAM memory
4. Synchronous Dynamic Random Access Memory (SDRAM)
5. Boot Flash
Boot parameters, system passwords, and license keys are saved in Non-Volatile Random Access Memory (NVRAM) so that they persist across reboots.
Q6
Which three statements are true about the bootloader? (Choose three.)
1. It decompresses the image file and loads it into the main RAM
2. It reads the image file
3. It is based on Linux
4. It looks at the boot parameters
5. It is a Windriver's VxWork product
The bootloader reads system boot parameters from NVRAM, locates and reads the software image file, decompresses it, and loads it into main RAM for execution.
Q7
You are configuring the boot parameters in the Session Border Controller. Which three statements are true about the boot parameters? (Choose three.)
1. A reboot is always required to apply any change to the boot parameters
2. The target name is used for domain name resolution
3. The system clock is a boot parameter
4. The boot parameters are stored in Non-Volatile Random Access Memory (NVRAM)
5. The boot parameters are not affected by the activate-config command
Boot parameters reside in NVRAM. Because they dictate low-level boot behavior rather than running application configuration, changes are unaffected by activate-config and require a system reboot to take effect.

Frequently asked questions

Who should take the 1Z0-404 exam?

The exam targets network architects, configuration consultants, configuration implementers, network administrators, project managers, support engineers, and system integrators. It is built for professionals who perform routine SBC operations—system access, ACLI configuration, backup and restore—and who already understand TCP/IP networking and VoIP telephony.

What topics are covered on the Oracle SBC 7 Basic exam?

The blueprint contains eight core topics: SIP essentials, SBC introduction, initial configuration, interface provisioning, SBC concepts (realms, steering pools, session agents, HMRs), Peering environment configuration, Access-Backbone configuration (registration caching, HNT), and SBC High Availability. Our practice questions are mapped to all eight so you can spot weak areas before test day.

What is Oracle's retake policy if I fail the 1Z0-404 exam?

Oracle requires a 14-day waiting period before you can retake a failed proctored exam, allows a maximum of 4 attempts within any 12-month period, and does not permit retaking an exam you have already passed. Schedule through Pearson VUE and plan your preparation so the first attempt counts.

How long is the 1Z0-404 certification valid?

Oracle certifications follow a periodic recertification model to remain active. Because the Communications SBC track evolves with new Acme Packet OS releases, candidates should expect to upgrade to a current version within the active window to keep the credential—and its associated OPN Specialization benefits—in good standing.

Is there a 1Z0-404 mock exam I can use for timed practice?

Yes. Our 1Z0-404 mock exam reproduces the real test's format—multiple-choice and single-choice questions drawn from the eight core topics—so you can rehearse pacing across the 180-minute window. Use it to build recall and confidence before sitting the live Pearson VUE exam.

How do the practice ACLI and realm-bridging scenarios compare to the live 1Z0-404 exam?

They are built directly from the official eight-topic blueprint and emphasize the same practitioner tasks—troubleshooting boot issues, SIP call flows, registration caching, and HA failover through ACLI. Explanations name the specific configuration element or SIP mechanism, so you learn the reasoning behind each answer rather than memorizing options.
