17、Your CDB has two regular PDBs as well as one application container with two application PDBs and an application seed. No changes have been made to the standard PDB$SEED. How many default temporary tablespaces can be assigned in the CDB? A) Seven B) Five C) Eight D) Three E) Six Answer:C 解析: seedpdb 也会有默认的临时表空间,其他的 CDB、APPROOT 和 pdb 都可以有自己的临时表空间, 把所有的总数加起来就是答案: ① CDB$ROOT(必须有默认临时表空间) ② PDB$SEED(默认情况下继承根容器的临时表空间,但可以单独指定) ③ Regular PDB 1 ④ Regular PDB 2 ⑤ Application Container(作为一个 PDB,可以有自己的默认临时表空间) ⑥ Application PDB 1(在应用容器内) ⑦ Application PDB 2(在应用容器内) ⑧ Application Seed(在应用容器内,类似 PDB$SEED,但用于应用 PDB 的模板)
