H12-891_V1.0-ENU exam is designed to validate the ability of the candidates to design, implement, and troubleshoot complex data communication networks. H12-891_V1.0-ENU exam is suitable for IT professionals who have a minimum of five years of experience in the field of data communication and who want to further their knowledge and skills in this area.

Q102. Link state information is isolated by default between different IS-IS processes on the same router.

TRUE

FALSE

Q103. The switch SWA and SWB are connected together by 2 Ethernet links, where the switch SWA has the following interface configuration:

Without changing the current configuration, GigabitEthernet1/0/1 and GigabitEthernet1/0/2 can join the same aggregation group

Because of the different VLANs allowed, GigabitEthernet1/0/1 and GigabitEthernet1/0/2 cannot join the same aggregation group

After link clustering is configured on both SWA and SWB, if MSTP is enabled on the switches SWA and SWB Both GigabitEthernetl1/0/1 and GigabitEthernetl/O/2 are the forwarding status of MSTP

Only if the configuration of GigabitEthernet 1/0/2 is changed to match GigabitEthernet 1/0/1 can the two join the same aggregation group

Q104. Router R1 runs the OSPF protocol, use the “display ip routing-table” command to view the routing table of the router R1, the following about the OSPF in the routing table.
Is the information described correctly?

In the routing table, route table entries identified by the “OSPF” identifier can only be learned through LSAs of Type 3

In the routing table, the routing table entries identified by the “OSPF” identifier can only pass Class 1 LSA

In the routing table, the routing table entries identified by the “OSPF” identifier can be learned through the 1/2/3/5 LSA

In the routing table, the routing table entry identified with the “O_ASE” identifier can only be learned by routing introduction

Q105. VPN instances are also known as VPN routing forwarding tables (PN Routing and Forwarding table), and there are multiple route forwarding tables on the PE, including a public route forwarding table, one or more VPN route forwarding tables, and VPNv4 Route forwarding table.

False

TRUE

Q106. In the laboratory network, the network is built according to the following topology diagram, SWI is the default configuration, and SW2 disables the switch STP function.

SG0/0/2 for WI enters the Discarding state

SW2 and G0/0/1 enters the Discarding state

SW2 G0/0/2 enters discarding state

No interface is backed up for blocking

SWI’s G0/0/1 enters the Discarding state

Q107. Comparisons for primary switch elections in the stack include?

MAC address

Health status

Stack priority

Stack ID

Q108. Run the SSM across the entire HW IP multicast network. The following about SSM understands correctly? (Multiple choice question)

No RP is required

SSM uses only shared trees

SSM uses only the SPT tree

Ideal for 1-to-many applications

SSM is recommended when you have multiple sources and expect to minimize the state of mroute in your network Ideal for many-to-many applications

Q109. An engineer performed the ingestion operation on an OSPF router in a network of the company, is the following statement about the introduction of the routing LSA correct?

The Advertising Router report is set to as the Router ID of ASBR

Net Mask is set to all 0

Link State lD is set as the destination network segment address

Using the Link State ID and Advertising Router, you can uniquely identify an LSA

Q110. Drag and drop

When sending a packet with a destination address of 4444, it is sent without labeling.

When the router receives a packet with the label 1024, it replaces the label with 1027 and sends it.

When a packet with a destination address of 2222 is sent, it is sent without labeling.

When sending a packet with a destination address of 3333, label 1026 and send it.

Q111. The Path Selection tool can define multiple entries, which of the following tools will automatically generate a rejection of any entries at the end of the slot

Community -filter

IP-prefix

Route policy

AS-Path- filter

Q112. If the Interface Sticky MAC function is enabled, what is the number of MAC addresses that the interface learns by default?

Q113. The following description of VRRP load sharing is correct? (Multiple choice questions).

When configuring priority, make sure that the same router acts as a master in the three VRRP backup groups

You can create multiple VRRP backup groups on one interface of a router . The router can act as a master for one VRRP backup group and as a backup for other VRRP backup groups

When you deploy load sharing, hosts in the same LAN are required to configure the IP addresses of different virtual routers as gateway addresses for missing provinces

VRRP load sharing requires at least two virtual routers to provide forwarding services at the same time

Q114. The following description of the characteristics of cross-domain VN-Optionc is correct?

A maximum of two layers of tags need to be used in the message forwarding process.

VPMV4 routes are not saved on the ASBR, and VPNv routes are not advertised to each other.

VPN routes are exchanged directly between the ingress PE and egress PE and do not require an intermediate device to secure a circular VPN route.

Cross-domain VN-Optionc, which is not suitable for use when spanning multiple AS.

Q115. The following statement about VXLAN gateways is incorrect

Layer 2 gateway: Used to solve the problem of tenant access to the VXLAN virtual network, it can also be used for subnet communication of the same VXLAN virtual network.

Layer 3 gateway: Used for cross-subnet communication of VXLAN virtual networks and access to external networks.

VXLAN Layer 3 gateways can be divided into centralized gateways and distributed gateways.

Layer 2 gateway and VPN instance binding.

Q116. Level-1-2IS transmits Level-2LSP to the Level-1 area if the AT location 1 in Level-2LSP is delivered It means that the Level-1lS in the area can be accessed to the outer area through Level-1-2IlS

True

False

Q117. Configuration under a certain interface: isis timer hello 5 level-2, the following statement is correct?

The hello packets sent at level-1 and Leve1-2 are both 5s

The hello packets sent at level-1 are sent at 5s interval

The level-2 hello packet send interval is 5s

The CSNP packet sending interval for this interface Level-2 is 5S

Q118. The fields that represent priority in the VLAN (8021Q) data encapsulation are a total of 6 bits.

True

False

Q119. The following description of the link state protocol is plausible?

CPU utilization is high and loops are easy to generate

Slow convergence and low CPU utilization

Fast convergence and low CPU utilization

Fast convergence and high CPU utilization

Q120. Which of the following options can affect the establishment of IBGP neighbors?

iBGP-Multi-hop is not configured

Authentication is unsuccessful

IGP routing is not passable

BGP protocol version inconsistencies

Q121. ::1/128 is the IPV6 loopback address

TRUE

FALSE
