1. B and E are correct. The essence of disaster recovery resides in understanding that it represents planned and practiced efforts, tools and mechanisms to respond to any kind of serious data, service or facilities event that prevents normal business or data processing functions from taking place. Answer A is incorrect because it represents planning prior to such events designed to avoid or limit their effects, not activity following such events to deal with the consequences. Answer B is correct because it occurs after the event and involves planning and practice to minimize the effects of such events. Answer C is incorrect because it does not specifically address disaster recovery approaches, techniques or mechanisms. Answer D is incorrect because disaster recovery techniques invariably concentrate on switchovers to backup sites, systems and copies of data on the assumption that original systems are out of service for the foreseeable future. Answer E is correct because it’s a crucial part of bringing the necessary data and systems together to restore operations after a disaster has occurred.
2. A is correct. The Appliance Manager application is the SANWorks Management Appliance application that enables control over appliance settings, configuration and properties, as well as restart or shutdown functions. Its capabilities also include backup and restore capabilities for Management Appliance configuration files. The HSG Element Manager is a Web-based enhanced SAN manager that makes it possible to use the Management Appliance to configure and monitor HSG-based storage subsystems. Thus, answer B is incorrect. Network View is an add-on product for the Management Appliance that automatically discovers and monitors both in- and out-of-band SAN devices and interconnects. Therefore, answer C is incorrect. Open SAN Manager provides a single point for Web-based SAN management for installation and configuration of SAN devices, storage and so forth. Thus, answer D is incorrect. Storage Resource Manager (SRM) is not a Management Appliance application per se, but rather, a Web-based monitoring, reporting and alerting tool for capacity planning and storage consumption management. It is not a Management Appliance application per se, so answer E is incorrect.
3. B and D are correct. When using Windows 2000 virtual disks or basic disks, Virtual Replicator (VR) can add capacity or grow volumes without rebooting at all. Therefore, answer A is incorrect. Indeed, VR permits new disks to be added to an existing pool to create a new pool, which may be subdivided into virtual disks of appropriate size. Thus, answer B is indeed correct. VR offers centralized, not decentralized disk storage, but does use storage pooling and virtualization. However, answer C is incorrect. Indeed, snapshots support non-disruptive data backup and can avoid the need to operate completely within limited backup windows or timeframes. Therefore, answer D is also correct.
4. D and E are correct. When the SANworks Virtual Replicator (VR) is installed, an SNMP Agent and an associated management information base (MIB) are automatically installed by default. The SNMP Agent is a process that gathers local management information based on requests from management applications that interact with it. The MIB is a database of management information that represents objects and associated values related to VR resources and activities. Thus, answers D and E are correct. CLI is the command line interface and is part of basic Management Appliance capability, not installed as part of VR; thus, answer A is incorrect. CIM stands for Compaq Insight Management and is part of a set of objects associated with managing desktop machines that have nothing to do with VR. Therefore, answer B is incorrect. DHCP Agent is a portable set of Unix-based DHCP utilities that has nothing to do with VR. Therefore, answer C is incorrect.
5. A, B, D and F are correct. Enterprise Volume Manager (EVM) host agent runs on a long list of platforms that include specifications as stated for items A (Windows NT 4.0 Server or Enterprise Server Service Pack 5, 6A or greater), B (Windows 2000 Server, Advanced Server and Datacenter Service Service Pack 2 or greater), D (Sun Solaris 2.6, 7 and 8) and F (Compaq Tru64 UNIX V5.1A). In addition EVM host agents also run on IBM-AIX 4.3.3 and HP-UX V11.0. This latter limitation explains why Answer E is incorrect (it says V10.0, not V11.0); the omission of any kind of Linux from this list explains why answer C is incorrect.
6. B is correct. By definition, Secure Path is a tool that’s part of Data Replication Manager (DRM). It’s designed to provide continuous data access to StorageWorks RAID array storage systems that may be running on Windows NT 4.0, Windows 2000, Novell NetWare, Sun Solaris, HP-UX and IBM AIX platforms. The Secure Path management utility offers continuous monitoring, supports multiple paths to devices and can identify failed paths and failed-over storage units. For load balancing devices can even be moved between paths. That’s why answer B is correct. Answer A is incorrect because Secure Path offers no encryption services. Answer C is incorrect because Secure Path manages virtual devices, not
