QUESTION 117
What can we infer from this graph? (Multiple choice)

There is a route entry on R1 to 172.16.1.4/32

There is no IS-IS routing entry in R1’s IP routing table

There are 6 routing entries generated by IS-IS in the IP routing table of R1

R1 has no route entry to 172.16.1.4/32

QUESTION 118
Regarding the BGP MPLS IP VPN network architecture, which of the following descriptions is wrong?

The P device only needs to have basic MPLS forwarding capabilities, and does not maintain VPN-related information

Sites can access each other through VPN, and a site can only belong to one VPN

In general, CE devices cannot perceive the existence of VPN, and CE devices do not need to support MPLS, MP-BGP, etc.

The BGP/MPLS IP VPN network architecture consists of three parts: CE (Customer Edge), PE (ProviderEdge) and P (Provider). PE and P are operator equipment, and CE is BGP/MPLS IP VPN user equipment

QUESTION 119
When configuring a RADIUS server template on a Huawei switch, which of the following options are optional configuration parameters?

Authentication server address and port

RADIUS automatic detection of users

Accounting server address and port

Shared-key

QUESTION 120
An engineer uses two routers to test IPv6 services, and simulates the interconnection between the headquarters and branches by running BGP4+.

As shown in the figure, an engineer captures the packet to view the update message sent by R1. Regarding the description of the message information, which of the following statements is correct?

The next hop address of the route described in this packet is :2001:db8::2345:1.:1

This packet describes the currently withdrawn IPv6 route

The routing address prefix described in this packet and its prefix length are :2001:db8:2345:1::1/128/

The route described in this packet may be imported through import

QUESTION 121
Which of the following is not a primary role in developing a project delivery process

Increase customer satisfaction

Clear division of responsibilities

Improve work efficiency

Reduce project risk

QUESTION 122
IS-IS supports the processing and calculation of IPV6 routes by adding TLVs to carry IPV6 addresses and reachability information.

TRUE

FALSE

QUESTION 123
After the cutover is completed, what items generally need to be checked? (Multiple choice)

Software Version

Physical topology

Data flow

Control Plane Entries

QUESTION 124
When BGP/MPLS IP VPN is deployed, the OSPF VPN Route Tag is not transmitted in the extended community attribute of MP-BGP, but is only a local concept, only on PE routers that receive MP-BGP routes and generate OSPF LSA Significant.

True

False

QUESTION 125
Since BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors. Deploying routing policies between IBGP neighbors is invalid.

True

False

QUESTION 126
In the label forwarding table of the MPLS device, for different routes (the next hop is also different), the label is sent out:

must be different

must be the same

may be the same

QUESTION 127
The end-to-end delay is equal to the sum of all processing delays and queue delays on the path

True

False

QUESTION 128
Which of the following description of the Confirm Failure phase in the Structured Network Troubleshooting Process is correct?

Should pay attention to how to better solve the fault regardless of whether the fault belongs to its own responsibility.

Attention should be paid to the opinions of users, and faults should be judged based on the judgment of users.

The impact should be minimized and others should not know that the network is down.

Should confirm whether the non-disabled work is within the scope of their responsibility.

QUESTION 129
When there are multiple redundant links in an IS-IS network, multiple equal-cost routes may appear. Which of the following statements is wrong about equal-cost routing within an IS-IS network?

When the number of equal-cost routes in the network is greater than the number configured by the command, and these routes have the same priority, the route with the larger next-hop device System ID is preferred for load balancing.

If load sharing is configured, the traffic will be evenly distributed to each link

After the equal-cost route priority is configured, when the IS-IS device forwards the traffic reaching the destination network segment, it will not adopt the load balancing method, but forward the traffic to the next hop with the highest priority

A priority can be specified for each route in the equal-cost route, and the route with higher priority will be preferred. the rest as backup routes

QUESTION 130
MPLS has the concept of forwarding equivalence class FEC. Which of the following description is wrong? (Multiple choice)

MPLS classifies packets with the same forwarding processing method into a class called FEC

A forwarding equivalence class FEC assigns unique label values on all routers

Groups of the same FEC will be handled differently in MPLS networks

The division of FEC is flexible. It can be any combination based on the source address, and the address, source port, destination port, protocol type or VPN, etc.

QUESTION 131
As shown in the figure, there is a packet containing a three-layer label header. Please select the values corresponding to the X, Y, and Z fields in the figure (decimal)
