Oracle Exam 1Z0-133 Topic 4 Question 104 Discussion

Actual exam question for Oracle's 1Z0-133 exam

Question #: 104
Topic #: 4

Identify two advantages of using a Single Client Access Name (SCAN) when configuring a GridLink data source. (Choose two.)

AThe Fast Connection Failover (FCF) pattern, which allows rapid failure detection, is enabled

BThe more sophisticated runtime connection load balancing (RLCB) is used; without SCAN, load balancing reverts to a simple round-robin scheme

CSCAN is required for the GridLink data source to use an XA driver

DThe database URL is shorter because it contains one SCAN alias and port as opposed to a host and port foe each RAC node

EThe data source configuration does not need to be updated when new nodes are added to the RAC cluster

Wait, is C a real thing? I thought XA was just for breakfast cereal. You learn something new every day!

Yes, and with SCAN, the database URL is shorter and configuration doesn't need updating when new nodes are added

D is a nice bonus, but I'm more excited about the fast failover. Gotta keep those apps up and running, you know? No time for database downtime.

Definitely, and having a shorter database URL with just one SCAN alias is a nice convenience too.

I think advantages of using SCAN are FCF pattern and RLCB

B is pretty neat too. That runtime load balancing is like having a traffic cop for your database connections. Keeps things running smoothly.

A and E, for sure! SCAN makes life so much easier when dealing with RAC clusters. No more fiddling with individual node URLs, and the automatic failover is a lifesaver.
