Changing the Concept of H12-261-ENU Exam Preparation 2022

NO.146 If running PIM-SM on a multicast network, you need to construct a multicast forwarding tree between the multicast source and the receiver to enable the receiver to receive multicast data. Which of the following description about the constructed multicast forwarding tree is correct? (Multiple Choice)

The RTP tree is built between the RP and the receiver.

The RPT tree is built between the multicast source and the RP.

The SPT tree is built between the RP and the receiver.

The SPT tree is built between the multicast source and the RP.

NO.147 In the MPLS-BGP-VPN environment, if the label is only distributed through BGP or LDP, the MPLS label of the packet has at most two layers of labels.

True

False

NO.148 As shown in the following scene, which description is true?

R1 has both Level-1 and Level-2 LSDB

R1 can ping the interface address of R21 1oopbapk0

R1 has a route to R2 1oopback0 10.0.2.2/32

No neighbor relationship can be established between R1 and R2.

NO.149 Configure AS-path-Filter ip as-path-filtr 10 permit_100$ means to match the route received from AS100.

True

False

NO.150 Which of the following is not included in the digital certificate?

Public key information

Digital envelope

Digital signature

Issuer

NO.151 What is the main reason why RSTP converges faster than STP?

RSTP increases the type of port status

RSTP has less overhead

RSTP is not based on timer convergence

RSTP has a smaller timer

NO.152 The path selection tool can define multiple entries, which of the following tools will automatically generate and reject any entries at the end of the configuration? (Multiple Choice)

Route policy

IP-prefix

Community -filter

AS-Path-filter

NO.153 Between the two directly connected devices that have established IBGP neighbor, run the shutdown command to shut down the interface of one of the devices. The BGP connection will not be disconnected immediately.

True

False

NO.154 Through the following displayed command, you can determine that switch loop fault is caused by ().

NO.155 About the description of MPLS lable related information, which of the following is wrong?

The length of the MPLS label is 4 bytes and it is encapsulated between the link layer and the network layer.

By default, the device supports the PHP feature, and the label value of the egress node supporting PHP which is allocated to the penultimate hop node is 3.

If the bottom mark of the label is S=0, it indicates that the label is the bottom label and directly performs IP forwarding.

When the tag value is 0, it indicates that the tag should be ejected, and the packet must be forwarded based on IPv4.

NO.156 Which is wrong about the EVPN Type 5 class routing?

The IP Prefix field can carry either the host IP address or the network segment address.

Type 5 is an IP prefix route.

Type 5 routing carries both Layer 2 VNI and Layer 3 VNI

Type 5 routing carries Layer 3 VNI.

NO.157 The following is about the RD attribute filter of BGP, what is the correct description? (Multiple Choice)

If RD-filter is configured, but the RD of the route does not match any of the RDs defined in the rule, the default match result is Permit.

The relationship between the rules configured by RD-filter is “or”

If RD-filter is not configured, but this RD-filter is used for filtering, the matching result is deny.

Matching multiple rules in the order of configuration

NO.158 Which of the following options may affect the establishment of IBGP neighbors? (Multiple Choice)

Authentication is unsuccessful

The BGP protocol version is inconsistent

IBGP-Multi-hop is not configured

IGP routing is unreachable

NO.159 Router HW is enabled with OSPF and the role of the router HW is ABR, and abr -surmnary is configured. Which classes of LSA will be aggregated? (Multiple Choice)

Type 4 LSA

Type 5 LSA

Type 2 LSA

Type 1 LSA

Type 3 LSA

NO.160 Now there is a network consisting of router R1, router R2, router R3 and router R4. These four routers are interconnected via a LAN network. Basic OSPF is deployed on all four routers. When you execute the command “display ospf peer” on the router R2, the status between router R2 and router R3 is “2way”.
So, what conclusion can you draw from this output? (Multiple Choice)

Router R4 is DR

Router R2 is a DR or BDR

Router R2 is not DR

Router R3 is neither a DR, nor a BDR

There is no full adjacency relationship between router R2 and router R3.

NO.161 In an existing OSPF network, which type of LSA will cause SPF calculation? (Multiple Choice)

Type 1 LSA

Type 3 LSA

Type 4 LSA

Type 2 LSA

Type 5 LSA

NO.162 There are two types of community-filter: basic community attribute filters and advanced community attribute filters. Which of the following filtering tools makes the advanced community attribute filter more flexible than the basic community attribute filter?

ACL

Regular-expression

AS-path-filter

IP-prefix

NO.163 Which of the following operations can implement fast fault detection on multicast network? (Multiple choice)

Shorten the Holdtime of Join/Prune messages

Reduce the interval at which the interface sends Hello messages.

Establishing PIM BFD session between neighbors

Reduce the interval for sending Join/Prune messages.

NO.164 Which of the following options is correct for the description of the optimal routing elections for various protocols?

OSPF puts all routing information in the LSDP into the IP routing table.

The route with the next hop unreachable in BGP is also put into the IP routing table.

Learn different routing entries to the same destination network segment from BGP and OSPF, and select the optimal route to join the IP routing table by comparing the preference value of the protocol.

Select the best route to the same destination network segment by comparing the cost value of the route entry in BGP protocol.

NO.165 Regarding BGP route filtering, which of the following description is wrong?

For a locally advertised route, configure a routing policy. The policy takes effect before the route is added to the BGP routing table.

The filtering relationship between the nodes of the Route-Policy is “OR”, that is, the Route-Policy can be passed with a node filter only.

When receiving a route from a BGP peer, perform a routing policy to filter unwanted BGP routes. These routes are not added to the local BGP routing table.

In the same node of Route-Policy, the relationship of multiple if-match clauses for different attributes is “OR”.
