102From the command output:[R2] display bgp group inRemote AS: 102...Type: internal...Peer Members:
10.1.3.3 4 10210.1.4.4 4 10210.1.5.5 4 102Key indicators:"Remote AS: 102""Type: internal"- This tells us that the BGP session isiBGP.IniBGP, both thelocalandremoterouters are in thesame AS.Since all remote peers (10.1.3.3, 10.1.4.4, 10.1.5.5) are inAS 102, and the session type isinternal, that means R2 mustalsobe in AS
102.Correct answer: 102In Huawei BGP implementation:If the BGP peer type is"internal", thelocal router and peer router are in the same AS.TheRemote ASshown in the display bgp group command refers to the AS number configured for the peer.Since the session type isinternal, thelocal AS = remote AS.

Huawei SD-WAN supports various intelligent traffic steering mechanismsto optimize link utilization andbalance network trafficacross multiple links.
#D. Traffic bandwidth-based traffic steering
This method ensures that traffic isdistributed across multiple links based on available bandwidth.
SD-WAN dynamically selects linksbased on their real-time bandwidth utilization,ensuring optimal performance and load balancing.

BGP EVPN Route Types in VXLAN:
BGP EVPN Type 2 Route (MAC/IP Advertisement Route)
Used forhost reachability advertisement.
Carries MAC and IP address information of endpoints.
Does not carry an IP Prefix field(Type 5 routes handle prefixes).
Correct Explanation of Answer Choices:#IP Address (B) is included- Used for host mobility and reachability.
#L3VNI (C) is included- Used forLayer 3 VXLAN routing.#L2VNI (D) is included- Used forLayer 2 VXLAN bridging.#IP Prefix (A) is not included in Type 2 routes- It is part ofEVPN Type 5 routesforprefix advertisement.

Comprehensive and Detailed Explanation:
#The Best Protection Against MITM and Spoofing Attacks:
#(D) Associating DHCP Snooping with IPSG (IP Source Guard) and DAI (Dynamic ARP Inspection) providescomplete protectionby:
Blocking rogue DHCP servers.
Preventing MAC/IP spoofing.
Ensuring only valid clients access the network.
#Why Not Other Options?
#(A) Configuring trusted/untrusted interfacesonly helpsblock rogue DHCP servers, but does not prevent spoofing.
#(B) Limiting MAC address learningprevents MAC flooding, but does not stopMITM attacks.
#(C) Checking the CHADDR field in DHCP Snoopinghelps detectspoofed requests, but does not block all MITM scenarios.

Understanding Network Monitoring Data Categories
#Network devices operate across three functional planes:
#A. Management Plane:
Handlesdevice configuration, authentication, and monitoring.
Example:SNMP, SSH, NETCONF logs.
#B. Data Plane (Forwarding Plane):
Handlespacket forwarding and switching.
Example:Interface statistics, traffic rates, dropped packets.
#C. Control Plane:
Handlesrouting, signaling, and protocol operations.
Example:BGP, OSPF, and MPLS signaling messages.
#D. Monitoring Plane (Incorrect Choice):
There is no "monitoring plane" in network architecture.
Monitoring tools collect data frommanagement, control, and data planes, butdo not form a separate plane.
Why is the Answer D (Monitoring-plane data)?
#Monitoring-plane does not exist as a separate category in network architecture.
#O&M tools collect data from management, control, and data planes, but do not define a separate "monitoring plane".
Real-World Application:
