A network technician is installing an HPE Aruba Networking CX 6300M switch and needs to provide power to several connected devices, including security cameras and wireless access points, using Power over Ethernet (PoE). The total power requirement for these devices is 400 watts.
When selecting a power supply for the switch, what hardware specification must the technician verify to ensure the switch can meet this demand?
- A . The total PoE power budget of the power supply.
- B . The number of 10GbE uplink ports.
- C . The switching capacity in Gigabits per second (Gbps).
- D . The airflow direction (front-to-back or back-to-front).
Which type of routing protocol dynamically adapts to changes in network topology and link status?
- A . Static routing
- B . Dynamic routing
- C . Distance-vector routing
- D . Link-state routing
A Network Operator is using a third-party Network Monitoring System (NMS) to create a network topology map and monitor the real-time bandwidth utilization on switch interfaces. The NMS uses open standards for polling devices.
Which long-standing, industry-standard protocol would the NMS use to poll the switches for this information?
- A . REST API
- B . LLDP
- C . SNMP (Simple Network Management Protocol)
- D . Telnet
A Network Technician has been given a list of `show` commands to validate the configuration of a newly installed HPE Aruba Networking CX switch. The technician needs to verify the status of all IP-configured interfaces on the switch, including VLAN interfaces (SVIs) and the out-of-band management port.
The technician wants a single command that produces a table-like output, with one line per interface, showing the interface name, its IP address, and its status.
Which of the following validation commands is the best tool for this specific purpose?
- A . `show running-config`
- B . `show interface brief`
- C . `show ip route`
- D . `show ip interface brief`

A Network Operator is troubleshooting a slow file transfer between a client and a server. The operator captures the traffic and observes that the TCP window size is frequently shrinking to a very small value.
What is the purpose of the TCP windowing mechanism?
- A . To specify the number of packets that can be sent before rebooting.
- B . To manage the flow of data and prevent the sender from overwhelming the receiver.
- C . To encrypt the data being transferred for security.
- D . To choose the routing path for the data to take.
What is the advantage of Multiple Spanning Tree Protocol (MSTP) over traditional STP?
- A . It supports load balancing across multiple instances.
- B . It requires fewer configuration changes in large networks.
- C . It has a slower convergence time than STP.
- D . It can only be used in networks with a single VLAN.
A Network Operator is explaining the difference between TCP and UDP to a junior technician, focusing on why a streaming video application might use UDP.
Which of the following characteristics are primary reasons for using UDP over TCP for real-time applications? (Select all that apply.)
- A . It guarantees the delivery of all packets in the correct order.
- B . It has a lower header overhead, which adds less data to each packet.
- C . It establishes a reliable, three-way handshake before sending data.
- D . It does not retransmit lost packets, which avoids increasing latency.
- E . It uses acknowledgements to ensure every segment is received.
Which of the following best describes the purpose of rate limiting in networking?
- A . Maximize network bandwidth
- B . Preventing unauthorized access
- C . Minimizing latency
- D . Ensuring fair distribution of resources
