NEW QUESTION # 83
Refer to the exhibit.

You are designing a data center network. This customer requests that you connect the data center core their firewalls. The customer uses six VRFs for segmentation, and the firewalls are responsible for handling traffic in all of the VRFs.
What is the recommended design for the links between the data center core switches and the firewalls?

A. Each link should be a routed-only port (ROP) in a /31 subnet.
B. Link 1 and Link 3 should be one VSX LAG. Link 2 and Link 4 should be another VSX LAG.
C. Link 1 and Link 2 should be one VSX LAG. Link 3 and Link 4 should be another VSX LAG.
D. All links should be in the same VSX LAG.

Answer: B

Explanation:
From the exhibit:
1. Links 1 and 3 connect the two VSX core switches to the active firewall.
2. Links 2 and 4 connect the two VSX core switches to the passive firewall.
Therefore, each firewall receives its own VSX multi-chassis LAG.

NEW QUESTION # 84
You are modernizing a customer's legacy three-tier architecture with an L3 spine and leaf topology. The CX switches in the topology will provide the overlay. The customer data center uses six VRFs. The customer has asked for service leaf switches to connect to two clustered firewalls, which route and filter traffic between the VRFs. How should the service leaf switches connect to the firewalls?

A. On four ROPs (two per switch), each ROP being in the default VRF
B. On two VSX LAGs, each of which carries one VLAN per VRF
C. On two VSX LAGs, which are in the default VRF
D. On four ROPs (two per switch), each ROP being attached to the six data center VRFs

Answer: B

Explanation:
Create one multi-chassis LAG to each firewall. Each LAG operates as a Layer 2 trunk carrying a separate transit VLAN for every VRF. HPE's validated border-leaf configuration uses two MC- LAGs-one to each firewall-with the external VRF VLANs permitted on both.

NEW QUESTION # 85
The customer operates a 24/7 production facility and is concerned that the migration will disrupt the production line. What are two ways to minimize or eliminate this disruption? (Choose two.)

A. Close the production site for at least 1 day to do a bing-bang approach
B. Create a Migration Plan which describes a phased approach, i.e. access layer first, distribution layer second, etc.
C. Whenever possible, ramp up the new infrastructure in parallel and do transparent switching from old to new core switch.
D. Replace one access switch at a time and patch the ports by using a patch plan.

Answer: C,D

Explanation:
To minimize disruption in a 24/7 environment, build the new infrastructure in parallel where possible and migrate gradually. Replacing one access switch at a time with a detailed patch plan limits the impact to small, controlled sections.
