質問 # 48
You are designing an overlay solution for two Data Centers based on the Aruba CX platform. Each Data Center has two rooms and each room is its own fabric. There is a requirement for multicast traffic to be supported across all data center rooms and fabrics. What needs to be done?
- A. Establish a separate data center interconnect fabric for multicast traffic only
- B. Change the design to use one fabric per site
- C. Change the design to extend a single fabric across all rooms and both sites
- D. Use HPE Aruba CX switches' selective split horizon feature
正解：D
質問 # 49
A customer currently has a three-tier architecture in which aggregation switches are the default gateways.
Pairs of aggregation switches use VRRP. You are migrating to an L2 two-tier architecturein which the core switches are the default gateways. How should you migrate the default gateway functionality?
- A. Use a DHCP server to assign servers new gateway IP addresses, which are configured on the new core switches
- B. Add the core switches to the aggregation switches' VRRP groups and use VRRP to fail over to the new switches
- C. Configure VSX active gateway on the new core switches using the current default gateway IP address as the virtual IP and a new virtual MAC address
- D. Configure VSX active gateway on the new core switches using a new default gateway IP address as the virtual IP and the existing VRRP MAC for the virtual MAC address
正解：B
質問 # 50
You are designing overlay solutions for two Data Centers. Each Data Center has two rooms and each room is its own fabric. What is the underlay routing protocol between each data center room?
- A. OSPF
- B. iBGP
- C. eBGP
- D. RIP
正解：C
質問 # 51
Mention two disadvantages of the End-of-Row or Middle-of-Row switches in Data Center design
- A. Longer, more complex cabling within the row
- B. Higher latency for rack-to-rack traffic within the row
- C. More equipment
- D. Lower port density and less scalable
正解：A、D
質問 # 52
In a multi-AS underlay design
- A. All spine switches are in the same AS while each leaf (VSX pair if used) are in their own AS
- B. Every spine and every leaf is in their own AS
- C. All spine and leaf switches are in one AS and the border leaf is in separate AS
- D. Every spine is in their own AS while all leaf switches in one AS
正解：A
質問 # 53
CX Switches come with trusted platform modules (TPM). What is the function of TPM?
- A. TPM is just a convenient name to allow users to connect to the switch securely
- B. TPM prevents customers from loading certificates signed by the CA of their choice to the switches
- C. TPM stores a certificate signed by GeoTrust Certification Authority (CA).
- D. TPM stores a certificate signed by an HPE Aruba Networking Certification Authority (CA).
正解：D
質問 # 54
PVLAN (Private VLAN) defines three types of VLANs under the same SVI

- B. Primary VLAN, Isolated VLAN and Customer VLAN
- C. Secondary VLAN, Isolated VLAN and Provider VLAN
- D. Primary VLAN, Isolated VLAN and Community VLAN
正解：D
質問 # 55
What is the transit VLAN that runs between VSX members?
- A. It is used as a keepAlive mechanism
- B. Must not be assigned IP addresses on any switch.
- C. Must be assigned identical IP address on both of the switches
- D. It is a routed VLAN allowed in the ISL to ensure that the two switches within a VSX pair can learn routes from one another, in potential failover situations
正解：D
質問 # 56
What is one difference between a QSFP28 LC BiDi transceiver and a QSFP28 MPO SR4 transceiver?
- A. The BiDi transceiver uses fewer fiber strands than the SR4 transceiver
- B. The BiDi transceiver supports splitting the bandwidth into multiple lower bandwidth links
- C. The BiDi transceiver requires single-mode fiber, while the SR4 transceiver supports multi-mode
- D. The BiDi transceiver supports lower bandwidth than the SR4 transceiver
正解：A
質問 # 57
Depending on a switch's role in the topology, the demands on various tables differ. Several HPE Aruba CX switch models support different profiles, each of which optimizes the correct table for a switch with the corresponding role:
- A. L3 Aggregates profile allocates more space to the routing table compared to L3 core profile
- B. L3 Aggregates profile allocates more space to the routing table compared to Spine switch
- C. L3 Aggregates profile allocates more space to the support more overlay host entries table compared to leaf switches
- D. L3 Aggregates profile allocates more space to the ARP/ND table compared to L3 core profile
正解：D
質問 # 58
Which of the following are deemed as Post-installation handover tasks
- A. Project budget details
- B. RFP
- C. Enable monitoring of new systems
正解：C
質問 # 59

- C. It only works with MMF fiber type
- D. The maximum speed it can achieve is 400 Gbps
正解：D
