ZCP Q and A
ZCP Certification Exam
Passing mark is atleast 75%, answers are highlighted in bold.
1) After performing a failover operation (Test, Live, Move) Zerto allows you to generate a report detailing the steps performed during the operation.
2) VPGs can only protect virtual machines running Mac OS X or Windows XP and newer.
3) To recover a single VPG after a corrupted database, which of these operations would be most effective?
- Journal file-level restore
- Offsite clone
- Live failover
- Backup restore
4) ZVR’s Journal is stored where?
- Production/source site
- Recovery/target site
5) During a VPG sync, which of the following operations can be performed? Select all that apply.
- Add a VM to the group
- Remove a VM from the group
- Change length of Journal history for the group
- Change hard limit of Journal size for the group
6) Offsite Backups for a VPG should be scheduled to run at least every four hours, but no more than every 12 hours.
7) How much memory can be allocated to a Virtual Replication Appliance?
- 1 GB
- 3 GB
- Between 1-16 GB
- Between 2-8 GB
8) If both sites (target/recovery and source/production) are up, healthy, and accessible, which VPG-level operation is most appropriate?
- Live Failover
- Offsite Clone
9) What basic method does ZVR use to protect data and applications?
- VM-level continuous replication
- Scheduled and on-demand snapshots
- Daily delta syncs
- Guest/agent-based replication
10) ZVR cannot function across different hypervisors, storage configurations, or host OS versions.
11) What must be true for a Move operation to be effective? Select all that apply.
- Both source (or production) and target (recovery) sites are up and accessible
- Each VM in the VPG has an up-to-date Journal
- The very latest copy of the data is required
- One of the site’s hosts has either a new VRA installed or an upgraded VRA
12) A fully configured ZVM on each paired site—e.g. production and recovery—requires which of the following? Select all that apply.
- Adding a site-specific license under Site Settings
- Creating matching VPGs on each site
- Installing VRAs on that site’s host(s)
13) Enabling auto-commit will always provide 30 minutes to validate the results of a failover before committing the changes.
14) ZVR has built-in support for scheduled bandwidth throttling that can work with or without other hardware/software also managing this.
15) What characterizes the kinds of VMs you should group together in the same VPG?
- Each are using the same datastore or volume for storage
- They need to maintain consistency with each other and all be failed over or recovered together
- All are running both the same OS and same hypervisor
- The journal is sized the same on each VM
16) Adding a VM to an existing VPG means… (Select all that apply)
- The entire VPG will be re-synchronized to ensure group consistency
- The VPG protection will need to be paused before adding the additional VM
- A checkpoint will be automatically inserted in the Journal prior to adding the VM
- A Live Failover cannot be executed until the updated VPG is fully synchronized
17) What is the Journal?
- Audit trail to track which operations were performed and when
- Series of checkpoints tracking block-level changes within VMs
- Detailed list of every snapshot, whether automatic or manually generated snapshots
- Compliance record of each VPG’s replication status at any given checkpoint
18) The ZVR installer includes which of the following components? Select all that apply.
- Local copies of the ZVR documentation specific to your hypervisor
- One license key for each site you’ll use with Zerto
- Microsoft .NET Framework in case the machine does not already have it installed
- VRA template for a custom-designed Zerto VM
- A Virtual Backup Appliance (VBA) for managing backups
19) If you needed to test the failover of an entire virtualized datacenter, what best practices should be followed? Select all that apply.
- Perform the test during off hours or on the weekend
- Clone the VPGs you want to test prior to starting the failover test
- Use an isolated/fenced network for testing
- Always stop the test from within ZVM and not your hypervisor’s management console(s)
- Provision a sandbox where ZVR can deploy the test VMs
20) What is a Virtual Replication Appliance?
- Lightweight agent installed on each VM in a protection group
- Snapshot engine that powers the ZVR Journal
- Custom Linux VM performing continuous replication
- A hypervisor plugin/add-on to manage cross-hypervisor replication
21) ZVR 4.5 allows for Journal Compression to increase storage capacity for journal history.
22) If the hypervisor service/admin account provided during installation is incorrect, ZVR will still proceed with the installation and ask for re-validation after installation is complete.
23) When configuring a Failover Test network, what is Zerto’s recommended best practice?
- Test and production network should be the same to ensure consistency
- Test network should be isolated/fenced
- The ZVM should be on a test network
- Pause replication on production network when using a test network during a test
24) What operating system is running on the VRA virtual machine?
- Red Hat Enterprise Linux
- Windows Server 2012
25) What VPG configuration option would give you the ability to stagger when and how your protected VMs start?
- Bandwidth Throttling
- Pre/Post Operation Scripting
- Boot Order Groups
