H12-831-ENU Dumps and Exam Test Engine

The HCIP-Datacom certification exam covers a wide range of topics, including routing and switching technologies, network security, WAN technologies, and network troubleshooting. Candidates will need to have a good understanding of these topics in order to pass the exam and obtain the certification.

Q213. As shown in the figure, OSPF is enabled on all interfaces of the router. The IP address marked in the figure is the IP address of the loopback0 interface of the device. Loopback0 of R1 and R2 is advertised in area 1, Loopback0 of R4 is advertised in area 0, and Loopback0 of R3 and R5 is advertised in area 2. Which of the following IP addresses can ping each other? (Multiple choice)

10.0.2.2 and 10.0.3.3 (Type 3 reception is not counted in non-backbone areas)

10.0.3.3 and 10.0.5.5 (same as region 1)

10.0.4.4 and 10.0.2.2 (normal calculation Type 3)

10.0.2.2 and 10.0.5.5 (Type 3 reception is not counted in non-backbone areas)

Q214. IS-IS is a link-state routing protocol that uses the SPF algorithm for route calculation. As shown in the figure, a campus deploys both IPv4 and IPv6 and runs IS-IS to achieve network interconnection, of which R2 only supports IPv4.

Which of the following statements is true about the topology calculation of this network?

If you want IPv4 and IPv6 network computation to form the same shortest path tree, you need to run the ipv6 enable topology ipv6 command to enable the IPv6 capability of the IS-IS process

By default, since R2 does not support Pv6

By default, IPv4 and IPv6 networks will be calculated separately to form different shortest path trees

By default, in the shortest path tree formed by IPv6 network calculation, the path from R1 to R4 is R1-R2-R4

Q215. OSPF is deployed in a small and medium-sized network. When checking the routing table of a certain device, it is found that only directly connected routes exist. Which operation is unlikely to cause the fault?

Routing protocol configuration error

Routing policy configuration error

Port address configuration problem

The configured user permissions are too low

Q216. Which of the following is not a hardware preparation for cutover?

Test the operation of the board

Power-on test

Device version check

Cable Continuity Test

Q217. Which of the following functional descriptions about eSight physical topology monitoring are correct? (Multiple choice)

Graphically display the layout and status of network elements, subnets, and links

Accurate and visualized monitoring of the network operation status of the entire network

The system shows the network structure of the whole network and the relationship between network entities in business

The entrance of the entire network monitoring realizes efficient operation and maintenance for customers

Q218. Which of the following reasons may cause the hosts in the same VLAN of the local area network to fail to communicate with each other? (Multiple choice)

Switch MAC address learning error

The interface is damaged by artificial shutdown or physical interface

Wrong port and MAC address binding is configured on the switch

Port isolation is configured on the switch

Q219. In the NFV architecture, what are the specific underlying physical devices? (Multiple choice)

Storage Devices

Network equipment

server

Air conditioning system

Q220. An engineer uses two routers to test IPv6. He wants to realize the interconnection of IPv6 networks by running OSPFv3. About the OSPFv3 related configuration that needs to be done on R1
, which are correct? (Multiple choice)

[R1-ospfv3-1-area-0.0.0.0] network 2001

[R1-GigabitE thernet0/0/1] ospfv3 1 area 0

[R1] router id 10.1.1.1

[R1-ospfv3-1] router-id 10.1.1.1

Q221. The Router LSA of a certain router is shown in the figure. Which of the following statements is wrong?

The Router ID of this router is 10.0.12.1

This router is the DR

This router has established an adjacency relationship

This router supports external route import

Q222. As shown in the figure, a sham link is established between PE1 and PE2 through the LoopBack0 interface. CE2 can learn the route of network segment 192.168.1.0/24 (the direct route on CE1) through the sham link and the backdoor link. If the default configuration is maintained, the cost of the route from CE2 to network segment 192.168.1.0/24 should be ( ). (Please fill in the Arabic numerals directly, without symbols)

Q223. What can we infer from this graph? (Multiple choice)

R1 has both level-1 and level-2 link status information

R1 only has level-2 link state information

In a level-2 network, there are a total of 8 routers

The system-ID of R1 is ee8c.a0c2.bafl

Q224. If the BFD session goes down, the direct link will fail.

TRUE

FALSE

Q225. BFD is only a general fast detection technology, which can realize fast switching function by itself, and it is not necessary to use it together with other fast switching technologies.

True

False

Q226. What shortcomings can RED technology solve?

TCP global synchronization phenomenon

TCP starvation phenomenon

Indiscriminate discard

Q227. In addition to the virtual connection, what type of IPv6 address is the source IPv6 address of the Hello packet of OSPFv3?

IPv6 anycast address

Unique local address

Global Unicast Address

Link-local address

Q228. In an MPLS network, SRs running the DP protocol exchange LDP messages to implement functions such as neighbor discovery, session establishment and maintenance, and label management. To ensure the reliability of message delivery, all LDP messages are sent and received based on TCP connections.

TRUE

FALSE

Q229. If no security policy is configured between firewall domains, or when searching for a security policy. If all security policies are not matched, the default interzone packet filtering action is executed by default is?

Only allowed to pass some part

Refuse to pass

Escalate to the administrator

Different default actions should be different

Q230. After the cutover is completed, what items generally need to be checked? (Multiple choice)

Software Version

Physical topology

Data flow

Control Plane Entries

Q231. IS-IS supports multiple instances and multiple processes, that is, one IS-IS router, multiple VPN instances can be configured to be associated with multiple IS-IS processes. Which of the following descriptions about IS-IS multi-instance and multi-process are correct? (Multiple choice)

One IS-IS process can only be associated with one VPN instance

If an IS-IS router creates multiple IS-IS processes, each process does not affect each other and is independent of each other

1 IS-IS process can be associated with multiple different VPN instances

1 VPN instance can be associated with multiple different IS-IS processes

Q232. When OSPFv2 evolves to OSPFv3, the LSA format and function are exactly the same, except that the network layer address in the LSA changes from IPv4 to IPv6.

True

False

Q233. What are the working modes of firewall interfaces? (Multiple choice)

Exchange Mode

Transparent Mode

Transmission Mode

Routing Mode

Q234. When deploying MPLS/BGP IP VPN, which of the following descriptions is wrong regarding the use of BGP to exchange routing information between PE-CE?

In the case of CE multi-homing, enabling BGP AS number replacement may cause routing loops. BGP SoD can be used to prevent routing loops in VPN sites.

When BGP is used to exchange routing information between PE and CE, if the autonomous systems where the two VPN sites are located use the same private AS number, the AS number replacement function can be used to replace the received private AS number with any specified AS number. The AS number in the network route to prevent the route from being discarded due to repeated AS numbers

In the Hub&Spoke scenario, when Hub-CE and Hub-PE use IGP, Spoke-PE and Spoke-CE cannot use EBGP

When BGP is used to exchange routing information between PE and CE, there is no need to import private network routes into BGP on PE.
