Question 2
SDWAN networks capitalize the usage of broadband Internet links over traditional MPLS links to offer more cost benefits to enterprise customers. However, due to the insecure nature of the public Internet, it is mandatory to use encryption of traffic between any two SDWAN edge devices installed behind NAT gateways. Which overlay method can provide optimal transport over unreliable underlay networks that are behind NAT gateways?
  1. TLS
  2. DTLS
  3. IPsec
  4. GRE
Correct answer: C
Question 3
Which best practice ensures data security in the private cloud?
  1. Use IPsec for communication between unsecured network connection
  2. Encrypt data at rest and in transition.
  3. Use the same vendor for consistent encryption.
  4. Anonymize data ownership to comply with privacy rules.
Correct answer: B
Question 4
As part of workspace digitization, a large enterprise has migrated all their users to Desktop as a Sen/ice (DaaS), by hosting the backend system in their on-premises data center. Some of the branches have started to experience disconnections to the DaaS at periodic intervals, however, local users in the data center and head office do not experience this behavior. Which technology can be used to mitigate this issue?
  1. tail drop
  2. traffic shaping
  3. WRED
  4. traffic policing
Correct answer: B
Explanation:
Traffic Shaping does help with congestion and better bandwidth utilization over the WAN.
