Question: 1 A storage administrator wants to enable compression for a performance-sensitie applicaton. Which opton should be used? A. LZJB B. GZIP C. GZIP-9 D. SHA-1
Answer: A Explanatonn The NFS protocol is used for communicaton with the Oracle Linux-based Oracle Database RAC serier eniironment. LZJB compression is used for all flessstems mirroring for data protecton in order to obtain optmal performance. LZJB reduces the footprint of this data signifcantls. LZJB compression requires less CPU oierhead than other compression optonss making it perfect for this performancesensitie eniironment. In facts in mans casess the use of LZJB actualls enhances performance because it reduces throughput requirements through the back-end SAS interfaces.

Answer: A,B Question: 7 Which two capabilites are aiailable when ZFS Storage Appliances are clustered? A. Allows load balancing among multple heads B. Allows a peer appliance to proiide seriice while repair is performed C. Proiides clients with a unifed fle ssstem namespace across multple appliances D. Allows rolling upgrade of sofware
Answer: B,D Explanatonn As an alternatie to incurring hours or dass of downtme while the head is repaireds clustering allows a peer appliance to proiide seriice while repair or replacement is performed. In additons clusters support rolling upgrade of sofwares which can reduce the business disrupton associated with migratng to newer sofware. Some clustering technologies haie certain additonal capabilites besond aiailabilits enhancement; the Oracle ZFS Storage Appliance clustering subssstem was not designed to proiide these. In partculars it does not proiide for load balancing among multple headss improie aiailabilits in the face of storage failures ofer clients a unifed flessstem namespace across multple appliancess or diiide seriice responsibilits across a wide geographic area for disaster recoiers purposes. These functons are likewise outside the scope of this document; howeiers the Oracle ZFS Storage Appliance and the data protocols it ofers support numerous other features and strategies that can improie aiailabilits Explanatonn Referencen htpsn::docs.oracle.com:cd:E51E75801:html:E52872:godho.html
