These hosts cannot access the internet. Therefore the host with ip address 200.0.12.8 does not belong to this range.

If the Telnet user level is set too low, the administrator might not have the necessary permissions to configure or modify the interface seBngs, including seBng IP addresses. This restric?on could prevent the alloca?on or modifica?on of interface IP addresses. 13. vty configura?on as shown in the figure, the user authority level is set to level 3.

(Mul?ple Choice) Op ons: A. Broadcas?ng method B. DNS C. DHCP D. Manually specified on AP Correct Answer: B, C (h ps://www.cisco.com/c/en/us/td/docs/wireless/access_point/cw916x/cw9164/installguide/b-hig cw9164i/installa?on-overview.html) Source: Huawei Official Website (h ps://support.huawei.com/enterprise/en/doc/EDOC1100081215) Source: Cisco Official Website Ques on 17: What is the maximum nego?a?on rate supported by the IEEE 802.11g standard? Op ons: A. 300Mbps B. 150Mbps C. 54Mbps D. 1200Mbps Correct :C Slide 16 Page 8 VERIFIED ANSWER: ABCD 19. Which of the following SNMP packets are sent to the NMS by the Agent on the managed device? A.Set-Request B.Get-Request C.Get-Next-Request D.Response Answer:D Source: Slide 18 (Network Management and OM) Page.No.16 Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1000178170/490ce67d/ipv6packet-format) Source: Lecture 19 (IP v6 Basics) Page.No.28 Source: Lecture 21(Network Programmability and Automa?on) Page.No.24 Verified Answer: ACD Source: Lecture 20 (Introduc?on to SDN and NFV) Page.No.19 Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1100193624/20c00492/reliabilitydesign#EN US_TOPIC_0276661504) Source: Lecture 3 (Huawei VRP) Page.No.29 Reason: When the silent-interface command is applied to an interface on RTA in an OSPF configura?on, it causes RTA to stop sending OSPF packets, including Hello packets, which are crucial for establishing and maintaining OSPF neighbor rela?onships. However, RTA will s?ll listen to and process OSPF packets received on that interface. Therefore, RTA will not form or maintain a neighbor rela?onship with RTB (op?on A), it will not send OSPF packets (op?on C), but it will con?nue to receive and process OSPF packets from RTB (op?on D). This confirms why B is incorrect and A, C, D are the correct responses. Source: Lecture 5 (IP Rou?ng Basics) Page.No.31 Source: Lecture 5 (IP Rou?ng Basics) Page.No.31 Reason: The correct answer is C: MAC-D, 11.0.12.1. This is because in a network where a router is used, when a packet needs to cross from one network to another (in this case from 10.0.12.1/24 to 11.0.12.1/24), the router's MAC address for the outbound interface (MAC-D) is used as the des?na?on MAC in the forwarded packet. 29. In the network shown in the figure below, assuming that all routers enable the OSPF protocol at the same ?me, which router is the BDR in this network? Reason: For elec?ng the DR and BDR we consider the priority of the routers. In the above example, there are two routers having the highest priority i.e. 255. Therefore, as both RTA and RTB has same priority, so now we have to consider the router id. The router with highest router id will be considered as DR which in this case is RTB. Whereas the router with second highest router id will be selected as BDR which in this case is the RTA. Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1100082074) Source: Lecture 4(Network Layer Protocols and IP Addressing) Page.No.20 33. Which of the following cannot be the length of the IPv4 packet header? A.32B B.60B C.20B D.64B Answer: D Source: Lecture 4(Network Layer Protocols and IP Addressing) Page.No.8 Verified Answer: A Reason: In OSPF (Open Shortest Path First) protocol, a Designated Router (DR) is elected on each mul?access network segment, such as Ethernet. Since the network diagram shows that each link between the routers (RTA, RTB, RTC, RTD) represents a separate Ethernet link and each is considered a mul?-access network, a DR will be elected on each of these links. Therefore, there are four separate segments, implying that each segment will elect its own DR. Hence, the total number of DRs elected across the network is 4. Verified Answer: D Verified By: Aleeza Mahsood Source: Lecture 5(IP Rou?ng Basics) Page.No.29 Reason: In this case, the des?na?on ip address is that of Loopback0 which is 10.0.2.2 with its mask of /32 with hop address of 10.0.12.2 of RTB to create a sta?c route. Source: Lecture 5(IP Rou?ng Basics) Page.No.14 37. As shown in the figure, if host A and host B want to achieve inter-VLAN communica?on through single-arm rou?ng, which configura?on should be done under the G0/0/1.1 interface of RTA? Source: Lecture 10(Inter VLAN Communica?on) Page.No.11 Reason: Reason: The router separates these groups of devices into two broadcast domains because routers do not forward broadcasts between their interfaces. There are 2 broadcast domains in this scenario: One for the switch and its connected hosts (all ports on the switch are in the same VLAN by default). One for the hub and its connected hosts. Reason: When we run shut down command on VLANIF 10 interface it state is changed to down. In order to recover it, run the undo shutdown command in the VLANIF interface view to start the VLANIF interface and aPer that its state will be again converted to UP and working. 40. The output informa?on of the sub-interface of a router aggregate port 1 is shown in the figure. Based on this informa?on, which of the following statements are correct? (Mul?ple Choice) [Router A]display Interface Eth-Trunk 1.100 Eth-Trunk1.100 current state : UP Line protocol current state : UP Last line protocol up ?me : 2019-03-04 10:22:40 UTC -08 :00 Descrip?on: HUAWEI, AR Series, Eth-Trunk1.100 Interface Route Port, Hash arithme?c : According to SIP-XOR-DIP, Maximal BW: 2G, Current BW: 2G, The Maximum Transmit Unit is 1500 Internet Address is 10.0.12.2/24 IP Sending Frames’ Format is PKTFIT ETENT 2.Hardware address 1s 00e0-fc3b-2015 Current system ?me: 2019-03-04 10:24:29 -08:00 Last 300 seconds input rate 0 bits/sec, 0 packets/sec Last 300 seconds output rate 0 bits/sec, 0 packets/sec Real?me 0 seconds input rate 0 bits/sec, 0 packets/sec Real?me 0 seconds output rate 0 bits/sec, 0 packets/sec Input: 6 packets, 574 bytes, Output:7 packets, 638 bytes, Input bandwidth u?liza?on ;0% Output bandwidth u?liza?on :0% Verified Answer: ABC Reason: The output lists two ac?ve ports (GigabitEthernet0/0/1 and GigabitEthernet0/0/2) under the aggregate port, indica?ng two links are present. The output explicitly states that the IP address for EthTrunk1.100 is 10.0.12.2/24.The sub interface number of the aggregate port is 100 - The interface name 'Eth-Trunk1.100' indicates the sub-interface number is 100. Reason: When Host A sends a data frame to Host B, the switch (SWA) uses its MAC address table to determine the outgoing port. Since the MAC address table of SWA shows that the MAC address of Host B (MAC-B) is associated with port GO/0/2, the switch will specifically forward the data frame to this port. Slide: Lecture 13 (AAA Principles and Configura?on) Page.No.2 43. On Huawei ARG3 series routers, what authen?ca?on modes does AAA support? (Mul?ple Choice) A.802.1x B.Local C.None D.HWTACACS Answer:BCD Slide: Lecture 13 (AAA Principles and Configura?on) Page.No.8 Source: (h ps://forum.huawei.com/enterprise/en/difference-between-the-ppp andpppoe/thread/667248010435903489-667213871523442688) Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1000173015/3ee10304/understandingsegment-rou?ng mpls) 46. The output informa?on of a certain device is shown in the figure. Which of the following statements is correct? (Mul?ple Choice) display interface G1gabitEthernet 0/0/0 G1gabi tEthernet0/0/0 current state : UP Line protocol current state : UP Route Port, The Maximum Transmit Unit is 1000 Internet Address is 10.0.12.2/24 IP Sending Frames' Format is PRTFMT ETENT_2.Hardware address is 00e0- fc22- 4fff Port Mode: FORCE COPPER Speed : 100.Loopback: NONE Duplex: FULL,Nego?a?on: DISABLE Md1 : AUTO Last 300 seconds input rate 24 bits/sec, 0 packets/sec Last 300 seconds output rate 24 bits/sec, 0 packets/sec A. The IP address of the interface is 10.0.12.2/24 B. The MAC address of the interface is 00e0-fc22-4fff C. The working rate of this interface is 1Gbps D. The MTU value of this interface is 1000 Answer: ABD Reason: The IP address "10.0.12.2/24" is explicitly listed under the interface proper?es, confirming the IP configura?on. The MAC address is directly given as "00e0-fc22-4fff," indica?ng the MAC address of the interface. The Maximum Transmit Unit (MTU) specified for the interface is 1000, clearly stated in the output. Op?on C is incorrect as the output men?ons "Speed: 100," sugges?ng the interface is opera?ng at 100 Mbps, not 1 Gbps. Verified Answer: D Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1100313446/874fdebf/ospfroute-selec?on-rules) Reason: Since the path A-C-D has the lowest cost of 60, therefore the path for RTA to reach the network will be of A-C-D. 50. Which of the following statements is correct? Source: Lecture 2 (Network Referencing Model) Page.No.8 Source: Lecture 7 (Ethernet Switching Basics) Page.No.23 Source: Lecture 7 (Ethernet Switching Basics) Page.No.24 Source:(h ps://support.huawei.com/enterprise/en/doc/EDOC1100278261/55c108dd/crea?ngand-dele?ng-a vlan) 55. By default, in the SNMP protocol, which port number does the agent process use to send alarm messages to NS? A.164 B.163 C.162 D.161 Answer: C Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1000060766/e35b53a6/snmpport-numbers) Reason: Modifying the IP address of the G0/0/1 interface (Op?on A) or closing it (Op?on B) directly disrupts the network path used by the Telnet session between Router A and Router B. Changing the IP address alters the rou?ng path, making the current connec?on invalid, while closing the interface terminates all data transmission, effec?vely severing the connec?on immediately. Both ac?ons result in an immediate loss of connec?vity for the Telnet session. Source: Lecture 15 (Network Services and Applica?ons) Page.No.7 Verified Answer: B Verified By: Aleeza Mahsood Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1000113315/2d2a4a3c/frequency-bandand-channel) 59.APer the link authen?ca?on is completed, the STA will con?nue to ini?ate link service nego?a?on. Which of the following messages is used to achieve the specific nego?a?on? A.Join B.Handshake C.Associa?on D.Nego?ate Verified Answer: C Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1100033726/e88c00c0/sta-access) Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1000069520/82ee2e5b/standalone-acsolu?on-core switches-and-acs-func?on-as-the-gateways-for-wired-and-wireless-usersrespec?vely) Verified Answer: B Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1100102755) 62. Which of the following working modes are supported by Huawei Enterprise AP? (Mul?ple Choice) A.Local B.Cloud C.FIT D.FAT Answer:BCD Source: Lecture 16 (WLAN Overview) Page.No.11 Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1100325245/3ee10304/understandingsegment-rou?ng mpls) Source: Lecture 17 (WAN Technologies) Page.No.19 Source: (h ps://support.huawei.com/enterprise/en/doc/EDOC1100290934/60bd56a0/snmpconfigura?on) Source: Lecture 18 (Network Management and OM) Page.No.16 67. The IPv6 address 2001: ABEF: 224E: FFE2: BCC0: CD00: DDBE: 8D58 cannot be abbreviated. A. True B. False Correct Answer : A Reason: There are no sequences of consecu?ve zero sec?ons (e.g., 0000:0000) that could be replaced with ‘::’. Therefore, the only possible abbrevia?on is the removal of a leading zero from any sec?ons that have them. In this case, the sec?ons either don’t have leading zeros to remove or, like CD00, the zero is not leading but a part of the significant value. Hence, it cannot be abbreviated.

Business plane C. Data plane D. Management plane Verified Answer: ACD Source: Lecture 20 (Introduc?on to SDN and NFV) Page.no.7 Source: Lecture 20 (Introduc?on to SDN and NFV) Page.no.41 Reason: Op on B: The router will forward data packets whose des na on network is 12.0.0.0/8: This is assumed correct based on typical rou?ng behavior where packets are forwarded unless explicitly denied or unmatched. Op on C: The data packet whose des na on network is 11.0.0.0/8 will be forwarded from the router's GigabitEthernet0/0/0 interface: This is directly confirmed by the rou?ng table showing an entry for 11.0.0.0/8 with the next hop via GigabitEthernet0/0/0. 72. Which of the following descrip?on about the Router ID of OSPF is incorrect? (Mul?ple Choice) Source: (h ps://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_ospf/configura?on/xe16/iro-xe-16- book/iro-cfg.html) Source: Lecture 5 (IP Rou?ng Basics) Page.no.15 Reason: Since the priority of direct routes is 0, therefore it has the highest priority. Source: (h ps://info.support.huawei.com/info-finder/encyclopedia/en/OSPF.html) 75. The route entry 10.0.0.24/29 may be aggregated from which of the following subnet routes? (Mul ple Choice) A.10.0.0.26/30 B.10.0.0.23/3o C.10.0.0.24/30 D.10.0.0.28/30 Verified Answer: ACD Reason: The route entry 10.0.0.24/29 covers the IP range from 10.0.0.24 to 10.0.0.31. Analyzing the op?ons, subnets 10.0.0.26/30, 10.0.0.24/30, and 10.0.0.28/30 fit en?rely within this range. Therefore, the correct op?ons are A, C, D.
