Q141. IBGP was established on two Between directly connected devices of neighbors, if the shutdown command is executed to shut down the interface of one of the devices, the BGP connection will not be disconnected immediately.

TRUE

FALSE

Q142. Which of the following LSAs are only spread within a single area? (multiple choice)

AS External LSA

Router LSA

Network LSA

Summary LSA

The firewall’s own security zone can be deleted

The same interface of the firewall can belong to different security zones

Different security zones of the firewall can have the same priority

Q144. A family user has opened a 10Mb/s bandwidth. In order to improve the user experience, the user can stabilize the speed at 12Mb/s.We use the token bucket technique to achieve this requirement, which of the following is optimal.

cir 10000 pir 12000

cir 10000 cbs 12000 pbd 12000

cir 8000 pir 12000

cir 10000 cbs 10000 pbs 12000

Q145. Which statement about multicast packet forwarding is correct?

RPFFailure to check indicates that multicast data packets are received from the suboptimal interface, but the inbound interface still receives multicast traffic and forwards it downstream.

IGMP The snooping function cannot control the scope of multicast traffic flooding on the Ethernet.

In the multicast transmission mode, the destination address of the packet can identify the location of the receiver

the source address of the multicast packet is the unicast address

Q146. DHCP The protocol can assign some parameter information related to ICP/IP to the client. In this process, DHCP defines a variety of packets. The encapsulation protocol used by these packets at the transport layer is:

UDP encapsulation

IPpackaging

PPP encapsulation

TCP encapsulation

Q147. When deploying MPLS/BGP IP VPN, regarding the use of BGP to exchange routing information between PE-CE, which of the following descriptions is wrong?

In the case of CE multi-homing, enabling the BGP AS number replacement function may cause routing loops. BGP So 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 AS number with any specified AS number. The As number in the private network route, to prevent the route from being discarded due to repeated AS numbers

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.

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

Q148. As shown in the figure, a company has built an OSPF network. The links in the figure all form an OSPF adjacency relationship, and all OSPF devices announce their own loopback interface addresses. One day, the two links of S1-R2 and S2-R1 suddenly failed. In order to check whether the network is running normally, the engineer checked the equipment status. Which of the following descriptions is correct?

R5 can learn the loopback route of R2 normally

R3 cannot learn the loopback route of R2

R1 can normally learn the loopback route of R2

R3 can learn the loopback route of R2 normally

Q149. in command aggregateate ipv4-address { mask | mask-length } [as-set I attribute-policy route-policy-name1 ldetail- suppressed I origid-policy route-policy-name2 |suppress-policy route-policy-name3], multiple parameters can be used toAffects summary routes and their results. Which description is correct about this command?

If As is configured-set, the AS_PATH of the summary route contains the AS path information of all specific routes to prevent routing loops

If Supp is configuredress-policy also generates aggregated routes. The if-match clause in Route-policy is used to select suppressed detailed routes. Detailed routes matching the Route-policy will still be advertised to other BGP neighbors

If Origin is configured-policy, only with Route Only the detailed routes matching the policy can participate in the aggregation

If Attrbute-policy is configured, you can change the attributes of the aggregated route

Q150. As shown in the figure, Client1 and Client2 serve as clients of RR1 and RR2 at the same time, RR1 and RR2 are in the same Cluster, and R1 introduces 10 routes. Assuming that the BGP configuration is correct and all neighbor relationships have been established, how many route entries exist in the BGP routing table of Client2?

Q151. The IPv6 link-local address can be generated through stateless automatic configuration.

TRUE

FALSE

Q152. BGP EVPNWhich of the following types of packets are required to implement virtual machine migration in a distributed gateway scenario?

Type5

Type4

Type1

Type2

Type3

Q153. Which type of address prefix in the following options indicates that the address is globally unique and globally routable among IPv6 unicast addresses, similar to the public address in IPv4?web address?

::1/128

FE80::/10

C00::/7

2000::/3

Q154. Which properties meet the following two conditions:
BGP router A can choose toWhether the Update packet carries this attribute.
If Router B receives aAfter the Update message, Router B does not recognize the attribute, but also advertises the Update message containing this attribute to Router C.
Router C may recognize and use this attribute.
(multiple choice) ( confirmed)

Aggregator

Local-Pref

Multi Exit-Disc

Community

Q155. BGP can only automatically aggregate routes whose source is Incomplete.

True

False

Q156. [R1]ospf 1
[R1-ospf-1]area 2
[R1-ospf-1-area-0.0.0 2] network 10.0.13.1 0.0.0.0
As shown in the configuration, the administrator has configured OSPF on R1, but R1 cannot learn the routes of other routers, so the possible reason is ().

This router does not have an OSPF process ID configured

The area ID configured by this router and the area I of its neighbor routersD is different

This router is not configured with the authentication function, but the neighbor router is configured with the authentication function

This router’s advertised network address does not match the interface mask

Q157. Two routers, connected together through serial ports, However, the interconnection cannot be pinged. Now check the port status as follows

Can you identify the cause from the above information? (Single Choice)

Insufficient link bandwidth

IP addresses at both ends are not on the same network segment

Inconsistent link layer protocols at both ends

Subnet mask mismatch

Q158. Regarding BGP4+, which of the following statements is correct?

BGP4+ carries the next hop address of IPv6 routes through the Next_hop attribute

There is no Next_hop attribute in BGP4+

BGP4+ carries the next hop address of the route through the Network Address of Next Hop in the MP_Reach_NLRI attribute

BGP4+ carries the prefix and mask length of IPv6 routes through the NLRI attribute

Q159. BFD judges whether a fault occurs by periodically detecting packets, which is a fast fault detection mechanism relying on routing protocols.

TRUE

FALSE

Q160. What command can be used to prevent users from accessing multiple devices through the HUB on the access port of the switch? (Single Choice)

[Huawei-GigabitEthernet0/0/1port trunk allow pass vlan 10
[Huaweijinterface GigabitEthernet 0/0/1

[Huawei-GigabitEthernet0/0/1 ]port link type access [Huawei-GigabitEthernet0/0/1]port isolate enable

Q161. Which of the following descriptions about the properties of BGP is correct?

The AS number of the adjacent AS, listed in the AS in the BGP routing entry_ The far right of the Path list.

BGP Speaker When the route learned from the EBCP peer is advertised to the IBGP peer, the next hop attribute of the route information is not changed.

Local Prefs are only valid between EBGP peers and are not advertised to third-party ASs.

A route can only have one community attribute value.

Q162. OSPRouter in F Lin included in LSAk What are the types of Type? (Multiple Choice)

StubNet

P-2-P

Vlink

TransNet

Q163. Which of the following is incorrect about BGP routing? (Single Choice)

Non-aggregated routes take precedence over aggregated routes.

in PrefVal, Local_ PIf the references are equal, if the BGP preference of the locally generated route, IBGP route, and EBGP route is the same, the locally generated route takes precedence.

See below entry in BGP routing table: * 172.16.1.11/32 0.0.0.0 100 ? Indicates that the route is available and non-optimal.

for next- Routes that are not reachable by the hop are invalid routes and do not participate in optimization.
