NEW QUESTION # 27
What can be done to dynamically set the PoE Priority on a switch port when deploying IP cameras APs. and other PoE devices?
Answer: B
NEW QUESTION # 28
Which feature can network administrators use to centralized RF planning and optimization service when using an Aruba mobility master architecture?
Answer: B
Explanation:
Explanation
AirMatch is a feature that provides centralized RF planning and optimization service for Aruba wireless networks. It uses cloud-based algorithms and machine learning to optimize the RF performance and user experience. References:https://www.arubanetworks.com/assets/ds/DS_AirMatch.pdf
NEW QUESTION # 29
You are in a meeting with a customer where you are asked to explain the network redundancy feature Multiple Spanning Tree (MSTP). What is the correct statement for this feature?
Answer: B
Explanation:
MSTP Multiple Spanning Tree Protocol. MSTP is an IEEE standard protocol for preventing loops in a network with multiple VLANs. MSTP allows multiple VLANs to be mapped to a reduced number of spanning-tree instances. configuration ID consists of two parameters: name and revision. The name is a 32-byte ASCII string that identifies the MSTP region, which is a group of switches that share the same configuration ID and VLAN-to-instance mapping. The revision is a
16-bit number that indicates the version of the configuration ID. By default, the MSTP configuration ID name is set to the switch IMC address, which is a unique identifier derived from the MAC address Media Access Control address. MAC address is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. of the switch.
NEW QUESTION # 30
When using the network check page in Central, what kind of tests can you run on switches?
(Select two.)
Answer: B,E
Explanation:
In Aruba Central's network check page, you can run several diagnostic tests on switches. A ping test is a common utility to check the reachability of a host on an IP network. A Power over Ethernet (PoE) check can help verify the power delivery status to PoE-capable devices. These tests are crucial for ensuring connectivity and power supply to network devices
NEW QUESTION # 31
Which field in a Layer 3 IPv4 packet header is used to mitigate Layer 3 route loops?
Answer: B
Explanation:
The field in a Layer 3 IPv4 packet header that is used to mitigate Layer 3 route loops is Time To Live (TTL). TTL is an 8-bit field that indicates the maximum number of hops that a packet can traverse before being discarded. TTL is set by the source device and decremented by one by each router that forwards the packet. If TTL reaches zero, the packet is dropped and an ICMP Internet Control Message Protocol (ICMP) Internet Control Message Protocol (ICMP) is a network protocol that provides error reporting and diagnostic functions for IP networks. ICMP is used to send messages such as echo requests and replies (ping), destination unreachable, time exceeded, parameter problem, source quench, redirect, etc. ICMP messages are encapsulated in IP datagrams and have a specific format that contains fields such as type, code, checksum, identifier, sequence number, data, etc. ICMP messages can be verified by using commands such as ping, traceroute, debug ip icmp, etc. message is sent back to the source device. TTL is used to mitigate Layer 3 route loops because it prevents packets from circulating indefinitely in a looped network topology. TTL also helps to conserve network resources and avoid congestion caused by looped packets. The other options are not fields in a Layer 3 IPv4 packet header because:
- Checksum: Checksum is a 16-bit field that is used to verify the integrity of the IP header.
Checksum is calculated by the source device and verified by the destination device based on the values of all fields in the IP header. Checksum does not mitigate Layer 3 route loops because it does not limit the number of hops that a packet can traverse.
- Protocol: Protocol is an 8-bit field that indicates the type of payload carried by the IP datagram.
Protocol identifies the upper-layer protocol that uses IP for data transmission, such as TCP Transmission Control Protocol (TCP) Transmission Control Protocol (TCP) is a connection- oriented transport layer protocol that provides reliable, ordered, and error-checked delivery of data between applications on different devices. TCP uses a three-way handshake to establish a connection between two endpoints, and uses sequence numbers, acknowledgments, and windowing to ensure data delivery and flow control. TCP also uses mechanisms such as retransmission, congestion avoidance, and fast recovery to handle packet loss and congestion.
TCP segments data into smaller units called segments, which are encapsulated in IP datagrams and have a specific format that contains fields such as source port, destination port, sequence number, acknowledgment number, header length, flags, window size, checksum, urgent pointer, options, data, etc. TCP segments can be verified by using commands such as telnet, ftp, ssh, debug ip tcp transactions, etc ., UDP User Datagram Protocol (UDP) User Datagram Protocol (UDP) is a connectionless transport layer protocol that provides.
