NEW QUESTION # 14
What is the purpose of Link Aggregation Control Protocol (LACP)?
- A. To detect rogue devices on the network
- B. To increase bandwidth by bundling multiple physical links
- C. To assign IP addresses dynamically
- D. To prioritize VoIP traffic
Answer: B
Explanation:
LACP (Link Aggregation Control Protocol) is a protocol used to combine multiple physical network links into a single logical link, known as a link aggregation group (LAG). This increases the overall bandwidth between two network devices, providing redundancy and load balancing for traffic across the aggregated links. LACP is part of the IEEE 802.1AX standard (formerly 802.3ad), and its primary purpose is to manage the aggregation of links to improve network performance and reliability.
NEW QUESTION # 15
Which two transport layer protocols operate at Layer 4? (Choose two.)
- A. ICMP
- B. TCP
- C. IP
- D. UDP
Answer: B,D
Explanation:
Both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) operate at the Transport Layer (Layer 4) of the OSI model. These protocols are responsible for managing the end-to-end communication and flow of data between devices on a network.
A). TCP (Transmission Control Protocol): TCP is a connection-oriented protocol that provides reliable, ordered, and error-checked delivery of data between applications. It ensures that data packets are delivered correctly and in the correct order.
B). UDP (User Datagram Protocol): UDP is a connectionless protocol that does not guarantee reliable delivery or ordering of data packets. It is used in applications where speed is more important than reliability, such as streaming media or online gaming.
NEW QUESTION # 16
A Solutions Architect is explaining the TCP three-way handshake process to a customer. What is the correct sequence of flags in the TCP headers for establishing a connection?
- A. ACK -> SYN-ACK -> SYN
- B. SYN -> ACK -> FIN
- C. SYN -> SYN-ACK -> ACK
- D. FIN -> FIN-ACK -> ACK
Answer: C
NEW QUESTION # 17
Which of the following best describes the purpose of rate limiting in networking?
- A. Preventing unauthorized access
- B. Minimizing latency
- C. Ensuring fair distribution of resources
- D. Maximize network bandwidth
Answer: C
NEW QUESTION # 18
A Network Operator is configuring QoS on an HPE Aruba Networking CX switch. The operator needs to classify traffic based on the application being used, such as distinguishing between HTTP and FTP traffic.
Which of the following is used to identify the application at Layer 4 for QoS classification?
- A. IP address
- B. VLAN ID
- C. MAC address
- D. TCP or UDP port number
Answer: D
NEW QUESTION # 19

NEW QUESTION # 20
Which of the statements is true about Rapid Spanning Tree Protocol (RSTP)? (Select two)
- A. It operates on a per-VLAN basis.
- B. It supports only a single spanning tree instance.
- C. It uses the same port roles and states as STP.
- D. It has a faster convergence time than STP.
Answer: B,D
NEW QUESTION # 21
What is the default subnet mask for an IPv4 Class C network?
- A. 255.0.0.0
- B. 255.255.0.0
- C. 255.255.255.0
- D. 255.255.255.255
Answer: C
Explanation:
In IPv4, Class C networks are typically used for smaller networks. The default subnet mask for a Class C network is 255.255.255.0, which allows for 256 IP addresses in total, with 254 usable host IPs (the first address is the network address, and the last is the broadcast address).
Class C networks have the first three octets (the first 24 bits) dedicated to the network portion, and the last octet (8 bits) available for host addresses, hence the subnet mask 255.255.255.0.
NEW QUESTION # 22
A Network Technician is running a new cable to a user's desk that is 80 meters from the wiring closet. The connection must support 1Gbps.
Which is the minimum category of Unshielded Twisted Pair (UTP) cable that should be used to guarantee this performance over the required distance?
- A. Cat6
- B. Cat5e
- C. Cat3
- D. Cat5
Answer: B
NEW QUESTION # 23
A Solutions Architect is conducting a final validation of a newly installed core switch. The architect needs to quickly get a high-level summary of the switch's health and resources. Which troubleshooting commands would provide a good "dashboard" view of the switch's overall health?
(Select all that apply.)
- A. `show system`
- B. `show logging -r`
- C. `show mac-address-table`
- D. `show running-config`

NEW QUESTION # 24
Which two benefits does QoS provide? (Choose two.)
- A. Reduces network congestion
- B. Increases network latency
- C. Prioritizes critical applications
- D. Increases packet loss
Answer: A,C
Explanation:
Quality of Service (QoS) is a set of techniques used to manage and optimize network traffic, ensuring that certain types of traffic receive priority over others. The two main benefits of QoS are:
C). Reduces network congestion: QoS can prioritize certain traffic types, helping to prevent congestion by ensuring critical traffic (such as VoIP or video conferencing) gets through the network even during periods of high demand. By managing bandwidth allocation, it can help reduce the impact of congestion.
D). Prioritizes critical applications: QoS allows administrators to prioritize traffic from critical applications, ensuring that important services (like real-time voice or video) receive the necessary bandwidth and low latency, even in times of high network usage.
NEW QUESTION # 25
A Solutions Architect is designing a routing solution for a branch office. The office has a core switch that needs to be configured to route between the local user VLAN (VLAN 10) and a server VLAN (VLAN
20). Additionally, all traffic destined for the internet must be forwarded to a primary firewall at
10.255.255.1. For redundancy, a secondary, floating static route should be configured to forward traffic to a backup firewall at 10.255.255.5 only if the primary path fails.
Initial State:
* The switch is in its factory default state, connected via the console.
* VLANs 10 and 20 are already created.
Required Configuration:
* Enable IP routing on the switch.
* Configure an SVI for VLAN 10 with IP address 192.168.10.1/24.
* Configure an SVI for VLAN 20 with IP address 192.168.20.1/24.
* Configure the primary default route to 10.255.255.1.
* Configure the backup default route to 10.255.255.5 with an administrative distance of 10.
Which configuration set correctly implements this routing design?
- A. ip routing
