NEW QUESTION # 43
A four-member HPE Aruba Networking CX 6200F VSF configuration is planned to replace the current
5412R switch. The customer has an open-source network management solution.
How should you respond to their question about monitoring the switches securely?
Answer: D
Explanation:
The correct answer is B. RESTful API is a secure way to monitor CX switches. HPE Aruba Networking AOS- CX supports a REST API as a management and automation interface. The REST API is accessed through HTTPS, which provides encrypted communication for management operations. This makes it a secure monitoring and automation option for a customer using an open-source network management platform that can integrate through APIs. Option A is incorrect because RMON is a monitoring feature, but it is not the best answer for secure modern monitoring access. Option C is not the best answer because using a dedicated out- of-band management port improves management-plane isolation, but it is not itself a monitoring protocol or method. Option D is incorrect because SNMPv2 is not considered secure; HPE Aruba hardening guidance recommends SNMPv3 instead of older SNMP versions because older versions lack authentication and encryption protections. Therefore, from the listed options, RESTful API is the best secure monitoring method for CX switches. ( arubanetworking.hpe.com )
NEW QUESTION # 44
A Network Operator needs to create a new subnet for a small department that requires exactly 12 usable IP addresses for its devices.
Which subnet mask or prefix length will provide the required number of usable host addresses with the least amount of wasted addresses?
Answer: B
NEW QUESTION # 45
How many broadcast domains are shown in the diagram below?
Answer: A
Explanation:
The correct answer is B. 2. The diagram shows two VLANs: VLAN 10 and VLAN 20. In Ethernet switching, each VLAN represents a separate Layer 2 broadcast domain. HPE Aruba Networking documentation defines a VLAN as a single Layer 2 network that can be partitioned to create multiple distinct broadcast domains, isolated from each other unless traffic passes through a router or Layer 3 interface. In this diagram, PCs A and B are in VLAN 10, so they share one broadcast domain. PCs C and D are in VLAN 20, so they share a second broadcast domain. The Layer 3 switch has SVIs for VLAN 10 and VLAN 20, which allow routing between the two VLANs, but the SVIs do not merge the broadcast domains. They provide Layer 3 gateways for each VLAN. Therefore, the number of broadcast domains is based on the number of VLANs shown, not the number of PCs, switch links, or SVIs. Since there are two VLANs, there are two broadcast domains.
NEW QUESTION # 46
Which is at the Transport Layer of the OSI model?
Answer: C
Explanation:
The correct answer is B. TCP port. The Transport Layer, Layer 4 of the OSI model, is responsible for end-to- end transport services between hosts. TCP and UDP operate at this layer, and TCP/UDP port numbers identify application conversations on a host. A TCP port is therefore a Layer 4 item. Option A is incorrect because an IP address belongs to Layer 3, the Network Layer, where logical addressing and routing occur. Option C is incorrect because a MAC address belongs to Layer 2, the Data Link Layer, where Ethernet switching and local delivery are handled. Option D is incorrect because a physical switch port is associated with the Physical Layer interface and Layer 2 switching behavior, not the Transport Layer. In HPE Aruba Networking CX configurations, ACLs also distinguish between IP addressing and Layer 4 protocol fields such as TCP or UDP ports, reinforcing that TCP port information is transport-layer information.
NEW QUESTION # 47
A switch port is up, but no traffic is being forwarded. What could be a possible reason?
Answer: A
Explanation:
The Spanning Tree Protocol (STP) is used to prevent loops in a network by designating one active path and blocking redundant paths. If a switch port is up but no traffic is being forwarded, it's likely that the port is in a blocking state due to STP. This means that STP has determined that the port is part of a redundant path and has blocked it to avoid network loops.
