  B. Access control to storage objects and Access Control Lists (ACLs)
  C. Access control to storage objects and auditing
  D. User authentication and Information Rights Management (IRM)
  A. Authentication and authorization

  Securing the Application Access Domain

  

  Access control services regulate user and host access to data. These services mitigate the threats of spoofing user identity and elevating their privileges. Both these threats affect data integrity and confidentiality. Access control mechanisms used in application access domain are user and host authentication (technical control) and authorization (administrative control). These mechanisms may lie outside the boundaries of the storage network and require various systems to interconnect with other enterprise identity management and authentication systems. NAS devices support the creation of access control lists that regulates user access to specific files. The Enterprise Content Management application enforces access to data by using Information Rights Management (IRM) that specifies which users have what rights to a document.

  A. Token ring
  B. Full mesh
  C. Bridged
  D. Core-edge
  D. Core-edge

  Core-Edge Topology

  The core-edge fabric topology has two types of switch tiers. The edge tier is usually composed of switches and offers an inexpensive approach to adding more hosts in a fabric.

  Each switch at the edge tier is attached to a switch at the core tier through ISLs. The core tier is usually composed of directors that ensure high fabric availability. In addition, typically all traffic must either traverse this tier or terminate at this

  tier. In this configuration, all storage devices are connected to the core tier, enabling host-to-storage traffic to traverse only one ISL. Hosts that require high performance may be connected directly to the core tier and consequently avoid ISL

  delays.

  In core-edge topology, the edge-tier switches are not connected to each other. The core edge fabric topology increases connectivity within the SAN while conserving the overall port utilization. If fabric expansion is required, additional edge

  switches are connected to the core. The core of the fabric is also extended by adding more switches or directors at the core tier. Based on the number of core-tier switches, this topology has different variations, such as, single- core topology

  and dual-core topology. To transform a single-core topology to dual core, new ISLs are created to connect each edge switch to the new core switch in the fabric. EMC E10-001 Student Resource Guide. Module 5: Fibre Channel Storage Area

• Question 279:

  Which remote replication solution has the highest bandwidth requirements?

  A. Array-based synchronous
  B. Array-based disk buffered
  C. Host-based asynchronous LVM mirroring
  D. Log shipping over IP networks
  A. Array-based synchronous

  ---

  Synchronous Replication Application response time is increased with synchronous remote replication because writes must be committed on both the source and target before sending the "write complete" acknowledgment to the host. The degree of impact on response time depends primarily on the distance between sites, bandwidth and quality of service (QOS) of, the network connectivity infrastructure. If the bandwidth provided for synchronous remote replication is less than the maximum write workload, there will be times during the day when the response time might be excessively elongated, causing applications to time out. The distances over which synchronous replication can be deployed depend on the application's capability to tolerate extensions in response time. Typically, it is deployed for distances less than 200 KM (125 miles) between the two sites. EMC E10-001 Student Resource Guide. Module 12: Remote Replication

• Question 280:

  When developing a disaster recovery plan, what is the result of choosing a particular recovery time objective for a system?

  A. Determines the type and location of the backup media
  B. Determines how often to take a backup of the system
  C. Determines how long to retain backup copies
  D. Determines how many transaction logs should be backed up
  A. Determines the type and location of the backup media

  Recovery-Time Objective (RTO): The time within which systems and applications must be recovered after an outage. It defines the amount of downtime that a business can endure and survive. Some examples of RTOs and the recovery

  strategies to ensure data availability are listed below:

  RTO of 72 hours: Restore from tapes available at a cold site. RTO of 12 hours: Restore from tapes available at a hot site. RTO of few hours: Use disk-based backup technology, which gives faster restore than a tape backup.

  RTO of a few seconds: Cluster production servers with bidirectional mirroring, enabling the applications to run at both sites simultaneously.
