databases Online Quiz - 24

BlackBerry Enterprise Solution uses transactional database replication to keep data synchronized between the messaging server (e.g., Exchange, Domino) and the BES databases. This ensures real-time consistency of user and device state.

BlackBerry Router is the service component that establishes and maintains connections between the BlackBerry Enterprise Server and the wireless network infrastructure. It routes data packets to and from the carrier network.

BlackBerry Enterprise Server supports integration with all three major enterprise messaging platforms: Lotus Domino (A), Microsoft Exchange (B), and Novell GroupWise (C). Each has a dedicated connector in BES.

BlackBerry Dispatcher is responsible for compressing and encrypting all data traffic between BES and handheld devices. It ensures data security and optimizes bandwidth usage through compression before transmission.

When a user is re-added to BES after being removed, messages that were previously on the device lose their synchronization context. The user cannot forward or reply to those old messages because they are no longer linked to the BES state.

BlackBerry was developed by Research In Motion (RIM), a Canadian technology company. RIM created and manufactured the BlackBerry line of smartphones and related services until rebranding as BlackBerry Limited.

Transactional replication is the correct answer because BlackBerry Enterprise Solution uses transactional replication to ensure data consistency across the database infrastructure. This type of replication replicates data transactions in real-time, which is essential for an enterprise messaging system where data integrity and synchronization are critical. Analytical processing is not a replication type, while merge and snapshot replication are less suitable for real-time enterprise messaging systems.

The BlackBerry Router is responsible for connecting to the wireless network (the BlackBerry Infrastructure) via port 3101. The Dispatcher manages encryption/compression, the Messaging Agent handles mail queues, and the Controller monitors server services.

ALL is the correct answer because BlackBerry Enterprise Server historically supported integration with all three major enterprise messaging platforms: Lotus Domino, Microsoft Exchange, and Novell Groupwise. This multi-platform support was a key feature that made BlackBerry popular in enterprise environments where different organizations used different email systems.

The BlackBerry Dispatcher handles the encryption, compression, and routing of data packets between the BlackBerry Enterprise Server and the BlackBerry Router. The Messaging Agent handles email synchronization, the Controller monitors services, and the Router manages external connections.

False is correct because when a user is re-added to the BlackBerry Enterprise Server (BES), they do not automatically regain access to their previous messages and the ability to forward or reply to them. Re-adding a user typically creates a new state, and historical message access is not preserved. This is a security and state management feature to ensure clean user lifecycle management.

24 hours is correct because the BlackBerry State Database (BBSD.nsf) is programmatically configured to be deleted after 24 hours as part of automated maintenance and cleanup routines. This prevents the accumulation of stale state data and helps maintain database performance. The 24-hour window is a standard retention period for temporary state information in the BlackBerry infrastructure.

9 is correct because the BlackBerry Enterprise Server infrastructure typically consisted of 9 core services including the BlackBerry Router, Dispatcher, Controller, Messaging Agent, Attachment Service, Sync Server, Policy Service, Monitoring Service, and Administration Service. These services work together to provide the complete BlackBerry enterprise functionality.

3DES (Triple DES) is correct because it was the default encryption method used in BlackBerry encryption for securing data transmission between the BlackBerry Enterprise Server and handheld devices. 3DES was the industry standard at that time, providing strong encryption for enterprise messaging. The other options (AED, 4DES, 3AED) are not standard encryption algorithms.

Data deletion or wiping of a BlackBerry handheld can also be initiated directly from the device settings or via security policies, not solely from the BlackBerry Enterprise Server (BES) manager. Therefore, the statement is false.

False is correct because user addition and deletion cannot be done directly from the BlackBerry Administration Service alone. These operations typically require the use of the BlackBerry Enterprise Server management tools or integrated directory services like Active Directory. The Administration Service provides monitoring and configuration, but user lifecycle management is handled through separate management interfaces.

Every BES has a unique SRP ID, shared CAL key and ID is correct because each BlackBerry Enterprise Server installation requires a unique SRP (Server Routing Protocol) identifier for authentication with the BlackBerry infrastructure, while the CAL (Client Access License) key and ID are shared across the organization for licensing purposes. This combination ensures proper server identification and license management.

Options->Advanced Options->Enterprise Activation is correct because this is the correct menu path to access the Enterprise Activation feature on BlackBerry handheld devices. The Enterprise Activation feature is located under Advanced Options in the device settings menu, which houses more complex configuration options. The other menu paths (Programs, direct Options, Administrator) are incorrect.

Checking for GPRS and EDGE to be in bold is correct because on BlackBerry handheld devices, when BlackBerry services are properly enabled and active, the network indicators (GPRS and EDGE) appear in bold capital letters in the status display. This bold formatting indicates that the data connection is active and authenticated for BlackBerry services. Just checking one or the other is insufficient.

BlackBerry messaging Agent is correct because the BlackBerry Messaging Agent is the service responsible for handling calendar data synchronization and processing in the BlackBerry infrastructure. While other services like Controller, Dispatcher, and Router handle different aspects of data flow, the Messaging Agent specifically manages calendar and messaging data processing.
