최신 Aruba Certified Switching Associate (ACSA) HPE6-A86 무료샘플문제 (Q53-Q58):

질문 # 53
Why would a device perform an ARP request?

정답：D

설명：
The correct answer is B. To find the destination MAC address for a specific IP address. ARP, or Address Resolution Protocol, is used on IPv4 Ethernet networks to map a Layer 3 IPv4 address to a Layer 2 MAC address. HPE Aruba Networking AOS-CX documentation states that ARP maps network addresses assigned to devices to physical addresses, and specifically maps IPv4 network addresses to Layer 2 MAC addresses on Ethernet networks. When a host wants to send traffic to another IPv4 device on the same local network, or to its default gateway, it must know the destination MAC address to build the Ethernet frame. If the MAC address is not already in its ARP table, it sends an ARP request asking which device owns the target IP address. Option A is incorrect because ARP is not used to find a source IP address. Option C is incorrect because the device already knows its own source MAC address. Option D describes reverse mapping, which is not the purpose of a normal ARP request.


질문 # 54
Which access control method involves granting access to network resources based on the physical address of the Network Interface Card (NIC)?

정답：B


질문 # 55
Which user group exists by default on an HPE Aruba Networking CX 8400 Series switch?

정답：B

설명：
The correct answer is A. operators. HPE Aruba Networking AOS-CX documentation for the CX 8400 identifies built-in user groups that exist by default on the switch. These include administrators, operators, and auditors. The operators group has limited privileges, such as basic display-only CLI access and the ability to view nonsensitive switch configuration information. It does not have full switch configuration privileges. The other options-helpdesk, servicedesk, and support-are not listed as built-in default user groups for the CX
8400. Those names could be created manually as custom local user groups in some environments, but they are not default AOS-CX groups. Therefore, from the available choices, the default group is operators.


질문 # 56
Which statement about Flash memory is true?

정답：B

설명：
The correct answer is C. The contents of Flash survive when a device reboots or powers down. In HPE Aruba switch operation, the active configuration used by the device while it is running is the running configuration.
The startup configuration is the saved configuration that is preserved and used after reboot. HPE Aruba documentation explains that saving the running configuration writes it to the startup configuration file in Flash memory, allowing the configuration to remain after the switch reboots. This confirms that Flash is nonvolatile storage. HPE Aruba AOS-CX documentation also describes eMMC or SSD switch storage as nonvolatile memory used for persistent storage of configurations, files, databases, and scripts. Option A is incorrect because switch Flash storage is not normally expanded by adding extra Flash for configuration storage. Option B is incorrect because the running configuration is held as the active operating configuration, not simply "Flash." Option D is incorrect because show running-config displays the current running configuration, not the saved startup configuration stored in Flash.


질문 # 57
The customer requires the highest speed available using a single port link between a CX 6200 and a CX 6300 over a distance of 1 meter (3 feet). Which is the correct validated connectivity option for a single port?

정답：D

설명：
Both the CX 6200 and CX 6300 support 25-gigabit SFP28 interfaces, and a 25G LR optic is a validated option that provides the highest available speed among the choices using a single port, regardless of the short distance involved.
