QUESTION 3
Which LAN configuration allows backups and replication to run simultaneously without potentially impacting backup performance on an EMC Data Domain system?

A.    Separate the traffic by using two separate Ethernet NICs
B.    Separate the traffic by using two separate VLANs on a NIC
C.    Reduce the traffic by using VLAN tagging on a NIC
D.    Reduce the traffic by using a larger MTU size

Answer: A

QUESTION 4
A customer has two EMC Data Domain systems deployed with a collection replication configuration. Based on best practices, what should be configured if the customer has less than 6 Mb/s throughput between the installation sites?

A.    Low bandwidth optimization
B.    Gz compression
C.    Initial replication seeding
D.    Bi-directional replication

Answer: A

QUESTION 5
An organization currently writes backups to an EMC Data Domain system and then creates encrypted copies of their backups on tapes. These tapes are then shipped to a third-party offsite vault.
They are now planning to deploy a second Data Domain system in a hosted disaster recovery site as a replication target to replace the use of the offsite tapes. The two sites are connected through an encrypted WAN link.
Where should encryption be applied on the Data Domain systems to ensure a similar level of data security as achieved by their current process?

A.    Encrypt the replication context
B.    Encrypt the data at rest
C.    Encrypt both the data at rest and the replication context
D.    None. The WAN link between the sites is already encrypted.

Answer: B

B.    B
C.    C
D.    D

Answer: B

QUESTION 7
An organization currently writes backups to an EMC Data Domain system and then creates encrypted copies of their backups on tapes. These tapes are then shipped to a third-party offsite vault.
They are now planning to deploy a second Data Domain system to a secure data center at their corporate headquarters as a replication target to replace the use of the offsite tapes. The two sites are connected through the Internet.
Where should encryption be applied on the Data Domain systems to ensure a similar level of data security as achieved by their current process?

A.    Encrypt the replication context
B.    Encrypt the data at rest
C.    Encrypt the data at rest and the replication context
D.    Encryption is not required

Answer: A
