What are two advantages of splitting a larger OSPF area into a number of smaller areas? (Select two)
正解：A、B
解説：
Splitting a larger OSPF area into a number of smaller areas has several advantages for network scalability and performance. Some of these advantages are:
* It increases stability by limiting the impact of topology changes within an area. When a link or router fails in an area, only routers within that area need to run the SPF algorithm and update their routing tables. Routers in other areas are not affected by the change and do not need to recalculate their routes.
* It reduces processing overhead by reducing the size and frequency of link-state advertisements (LSAs).
LSAs are packets that contain information about the network topology and are flooded within an area.
By dividing a network into smaller areas, each area has fewer LSAs to generate, store, and process,
* which saves CPU and memory resources on routers.
* It reduces bandwidth consumption by reducing the amount of routing information exchanged between areas. Routers that connect different areas, called area border routers (ABRs), summarize the routing information from one area into a single LSA and advertise it to another area. This reduces the number of LSAs that need to be transmitted across area boundaries and saves network bandwidth.

What is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports?
正解：D
解説：
This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.

Due to a shipping error, five (5) Aruba AP-515S and one (1) Aruba CX 6300 were sent directly to your new branch office You have configured a new group persona for the new branch office devices in Central, but you do not know their MAC addresses or serial numbers The office manager is instructed via text message on their smartphone to onboard all the new hardware into Aruba Central What application must the office manager use on their phone to complete this task?
正解：A
解説：
Explanation
Aruba Installer App is a mobile app that simplifies site installations and enables network connectivity for Aruba devices. The app allows the user to scan the barcode of the device and add it to the network using Aruba Central. The app also automates importing Aruba devices into Aruba NetEdit for intelligent configuration management and continuous conformance validation
質問 # 50
Which statements are true regarding a VXLAN implementation on Aruba Switches? (Select two.)
正解：A、B
解説：
Option A: MTU size must be increased beyond the default
This is because option A shows how to configure the MTU size for VXLAN tunnels on Aruba switches using the interface command and the vxlan command. The MTU size must be increased beyond the default value of 1500 bytes to accommodate the VXLAN header and payload2.
Therefore, option A is true regarding a VXLAN implementation on Aruba switches.
Option B: VNIs encapsulate and decapsulate VXLAN traffic
This is also true regarding a VXLAN implementation on Aruba switches. VNIs are used to encapsulate and decapsulate VXLAN traffic between two devices, such as a switch and a server. VNIs are also used to map VXLAN tunnels to overlay networks3.
Therefore, option B is also true regarding a VXLAN implementation on Aruba switches.
VXLAN is a Layer 2 encapsulation technology that substitutes the usage of VLAN numbers to label Ethernet broadcast domains with VXLAN numbers. VXLAN supports 224 Ethernet broadcast domains or VXLAN numbers. A VXLAN number ID is referred to as VNI. There is a one-to-one relationship between an Ethernet broadcast domain and a VNI. A single Ethernet broadcast domain can't have more than one VNI.
質問 # 51
A customer wants to provide wired security as close to the source as possible The wired security must meet the following requirements:
-allow ping from the IT management VLAN to the user VLAN
-deny ping sourcing from the user VLAN to the IT management VLAN
The customer is using Aruba CX 6300s
What is the correct way to implement these requirements?
正解：A
解説：
An inbound ACL is applied to traffic entering a port or VLAN. An outbound ACL is applied to traffic leaving a port or VLAN4. To deny ping sourcing from the user VLAN to the IT management VLAN, an inbound ACL on the user VLAN should be used to filter icmp echo traffic toward the IT management VLAN. Icmp echo-reply traffic is not needed to be allowed because it is already permitted by default5. References: 4
