VCAP5-DCA vs VDCA550

So what has changed in the Exam Blueprint for the VDCA550 exam?

• Section 1.2, The number of live lab activities (VDCA550; 23 and VDCA510; 26).

• Section 1.6, The Time limit has changed (VDCA550; 180 minutes and VDCA510; 210). Both an additional 30 minutes for non-native English speakers.

• Section 1.12, the environment available during the exam is described in greater detail in the VDCA550 Blueprint. Also, the vSphere 5.5 environment consist of five ESXi 5.5 hosts, two vCenter 5.5 Servers, vCOPS 5.6 Foundation, vCenter Orchestrator 5.5 and vSphere Replication 5.5 appliances plus an Active Directory domain controller and shared storage.

• Section 1.13 presents an overview of the documentation available during the exam; links to the actual documentation are included in the Blueprint. You won’t find this overview in the VDCA510 Blueprint.

• Under the Objectives, all “Knowledge sections” have been disappeared in the VDCA550 Blueprint. Although some parts moved to the “Skills and Abilities” section.

• The VDCA550 Blueprint does not have a separate Troubleshooting section. Some troubleshooting objectives have been moved to other objectives.

• The VDCA510 Blueprint has a total of 9 sections; the VDCA550 Blueprint has 7 sections.

New Skills and Abilities been marked as “NEW”.
Other Skills and Abilities moved to a new location, e.g. “Configure Software iSCSI port binding” is now part of Objective 1.1. But in the VDCA510 exam it was part of Objective. 1.3, so it has been marked as: “VDCA510 Obj. 1.3”.
