Q318. Regarding route introduction, what is the following description of the error?

BGP supports both import and network when generating routes, and the network mode is more precise.

By default, OSPF introduces an external route with a default metric of 1, and the level-2 network of the ingested external route type type, Type2

ISIS, routes to Level After the 1 makes a route ingestion, if you do not manually configure the ingestion policy, a bad route will be formed.

Introducing IBGP routing in OSPF may cause routing loops

Q319. Unlike STP, RSTP has only one BPDU type, its value is 2, and there is no TCN BPDU.

TRUE

FALSE

Q320. In an MPLS VPN network, different CE devices exchange routing information with the same PE device using different routing protocols, and different CE devices use routing protocols that are independent of each other

True

False

Q321. OSPFV is the GP running on the P4 network) OSPF3 is the KGP running on the IP6 network. OsPFV works the same basic way as OSPF2, such as elections for DR and BDR. As shown in the figure, an engineer uses three routers for IP6 service testing, and he wants to interconnect the IPv6 network by running OSPFv3 Which of the following statements is correct regarding the election of the network DR?

After the network converges, R1 is DR

After the network converges, the engineer modifies the priority of R1 to 100, the priority of R2 to 10, and R3 to the default value. When the network converges again, Rl is DR and R2 is BDR

After the network converges, the broadcast link adds a device, R4, with a priority of 150 When the network converges again, R4 is DR

After the network converges, R1 is powered off and restarted, and when the network converges again, R3 is DR

Q322. In inter-domain packet filtering, which of the following options belongs to the outbound direction?

trust –>Local

untrust–> dmz

trust–> untrust

untrust–> trust

Q323. Is the following description of the BSR/RP mechanism correct?

PIM-SM domain can have more than one C-BSR, but only one BSR can be elected by the C-BSR that receives the C-RP Packets are collected C-one RP information

BSR advertises BSR and C-RP information to all routers in the PIM-SM domain by flooding Bootstrap packets

A C-BSR can also collect C-RP information by receiving C-RP packets

Q324. The following about the Router-LSA of OSPFv3 is correct?( Single choice questions).

The router-LSA data area contains the Link-Local address

The router-LSA data area contains the Interface ID of the neighbor on this side

Similar to OSPFv2, the Option field exists in the header of LSA, not in the data area of Router-LSA

When LS type= Ox0001 in the head of LSA, the data area representing LSA is Router-LSA

Q325. What about the description of IGMP Snooping, is it correct?

IGMP Snooping solves the problem of multicast messages broadcasting in layer 3

IGMP Snooping does not consume the CPU of the switch

IGMP Snooping establishes a MAC multicast address table by listening for IGMP packets sent by the host

IGMP Snooping runs at the link layer and is a multicast constraint mechanism on Layer 2 Ethernet switches that manages and controls multicast groups

Q326. What is the field that the IPv6 header has similar to the IPv4 header “Type of Service” field?

Version

Flow Label

Next Header

Traffic Class

Q327. Four routers R1, R2, R3, and R4 run IS, and the I5S router type is noted in the diagram. All four routers have an area address of 49001, and looking at the routing table on R1l shows the following results, the reason why R did not reach the route of 1034344

The routing policy configured on the ARO filters the System-ID of the default route

R2 from conflicting with R3

R and R4 Zone Planning Errors The System-ID of

R2 conflicts with R1

Q328. 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

Q329. VrRP priority is not configured as O, devices that issue VRRP priority of 0 stop participating in the VRRP backup group, notifying the backup device to become a laster device as soon as possible without having to wait until the Master_Down_Interval timer times out

True

False

Q330. Which of the following are used in Ethernet?

A MAC address in a non-canonical format

CSMA/CD in multiplexed interviews

Mac address in canonical format

8025 encapsulated frames

8023 Encapsulated Frame

Q331. In an MPLS BGPVPN networking that does not enable MPLS penultimate hop pop-up technology. When the message reaches the last hop PE, the message has two layers of labels, and the two layers of label values can be the same.

TRUE

FALSE

Q332. Assuming that the shaping rate of a port is 10OMbps, the input loans and RIP of P configurations of each service of the interface are as follows: Then after the first round of scheduling, EF How many loans are allocated by the queue?( Single choice questions).

30M

15M

90M

25M

Q333. What are the problems with manually creating static VXLAN tunnels in campus networks? Multi-select

Although the static VXLAN tunnel mode can support distributed gateway application scenarios, the configuration workload is large and the configuration adjustment is complex

N devices to establish static VXLAN tunnels, you need to manually configure up to N(N-1)/2 tunnels, the amount of configuration is large

VTEP can only learn remote MAC addresses in a way that relies on data flooding

Static VLAN tunnel also uses related protocols on the control plane, which will cause equipment resource loss

Q334. In cross-domain VPN-OptionB packet forwarding, two ASBRs exchange the same LSP tags once.

True

False

Q335. In order to configure M4, you first need to define a RADIUS server, which is defined as follows:
Huawei]radius-server template EXAM
[Huawei-radius-EXAM]radius-servershared-key cipher HUAwei123(Huawei-radius-EXAM]radus-server authentication 10766661812(Huawei-radius- EXAM]radius-server authorization 1076666
1812[Huawei-radius-EXAM]radius-server accounting 10766661813 (Huawei-radius EXAM]radius-server retransmit 2

True

False
