NEW QUESTION 141
Which of the following community attributes can ensure that the propagation scope of BGP routing entries is only within the AS?

No_Export

No_Export_Subconfed

Internet

No_Advertise

NEW QUESTION 142
Which of the following tools cannot be used to match BGP routing entries?

Community Filter

IP Prefix List

NEW QUESTION 143
In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.
Label, a description of the two-layer label in the following options. What is wrong is:

MPLS VPNThe outer label is made byLDPprotocol or statically assigneD. the inner label is assigned by the correct end MP-BGPassigned by neighbors

By default, the outer label is popped before the packet is forwarded to the last hop device

M PLS VPNThe outer layer is labeled as a private network label, and the inner layer label is called a public network label.

Layer labels are used inPEThe device sends the packet correctly to the correspondingVPNmiddle

NEW QUESTION 144
During the test phase of the cutover, the criteria to indicate that the test has been completed are:

IPThe configuration view result of the device is normal as the standard

Test that the network service is normal as the standard

The upper-layer application service test carried by the network is normal as the standard

D, check that the network is running normally as a standard

NEW QUESTION 145
When OSPFv2 evolves to OSPFv3, the format and function of LSA are exactly the same, except that the network layer address in LSA changes from IPv4 to IPv6.

TRUE

FALSE

NEW QUESTION 146
Compared with the OSPFv2 packet header, which fields are added in the OSPFv3 packet header?

IPV6 Auth Type

Link ID

Instance ID

IPV6 Router ID

NEW QUESTION 147
Regarding BGP/MPLS IPVPN routing interaction, which of the following descriptions is wrong?

The egress PE can send IPv4 routes to the remote CE through BGP, IGP or static routing

After the egress PE receives the VPNv4 route advertised by the ingress PE, it filters the VPNv4 route according to the RT attribute carried by the route

The exchange between PE and CE is IPv4 routing information

The ingress PE changes the IPv4 route received from CE to VPNv4 route, and saves it according to different VPN instances

NEW QUESTION 148
Configure ipv6 preference in IS-IS protocol view. The function of this command is to configure the preference of IPv6 routes generated by lS-Is protocol.

TRUE

FALSE

NEW QUESTION 149
As shown in the figure, private network routing information is exchanged between PE1 and PE2 and their respective CEs through OSPF, and the same DomainlD is set on both PE1 and PE2. When routes are imported from BGP to OSPF on PE2, it is possible that Which of the following types of SAs are passed to CE2?

Typel LSA

Type3 LSA

Type7 LSA

Type5 LSA

NEW QUESTION 150
When deploying BCPIMPLS TP VPN, the OSPF VPN route tag (VPN Route Tag) is not transmitted in the MP-BGP extended community attributes. It only makes sense on PE routers that receive MP-BGP routes and generate OSPF LSA.

TRUE

FALSE

NEW QUESTION 151
As shown in the figure, which of the following statement is correct? (Multiple choice)

There are 8 MA networks in area 0

There are 4 MA networks in area 0

There are 4 routers in area 0

There are 8 routers in area 0

NEW QUESTION 152
As shown in the figure, the carrier BGP/MPLS IP VPN backbone network constructs SP through DP. If you want to realize the intercommunication between the two sites of user X through the BGP/MPLS IPVPN network, the 32bit mask of Loopback interface address must be used between PE1 and PE2 to establish the MP-IBGP peer relationship.

TRUE

FALSE

NEW QUESTION 153
An enterprise purchased the leased lines of two operators. In order to optimize the route, the enterprise used the 6GP protocol to learn routing entries of the two operators. However, the company found that after such a configuration, the traffic of the export routing increased greatly. After the network engineering investigation, it was found that the traffic of the two operators was passed to each other through the company’s export router.

Therefore, the company intends to use routing strategies to prevent the traffic between different operators from passing each other. Is the configuration in the figure correct?

TRUE

FALSE

NEW QUESTION 154
Which statements are wrong about OSPF Router LSA and Network LSA? (Multiple choice)

The router running DSPF must generate Network LSA

Routers running OSPF must generate Router LSA

There must be both Router LSA and Network LSA in the OSPF network

Network LSA carries both topology and routing information

NEW QUESTION 155
Please match 0SPFv3LSA with its transmission range.

LinkLsAlocallinkrange

AS-external-LSA Autonomous system-wide intra-regional propagation
Network-1SA intra-regional spread

NEW QUESTION 156
As shown in the figure, all interfaces of the router enable OSPF. Which of the following statements is correct?

The Type1 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information

The Type5 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information

The Type2 LSA generated by R2 in area 0 contains 10.0.2.2/24 routing information

The Type3 LSA generated by R2 in area 0 contains 10.0.2.2/32 routing information

NEW QUESTION 157
In an MPLS network, SR running the DP protocol exchange LDP messages to realize functions such as neighbor discovery, session establishment and maintenance, and label management. In order to ensure the reliability of message delivery, all sending and receiving of LDP messages must be based on TCP connections.

FALSE
