NO.60 RD is used to distinguish between the same IP address in different VPNs, and how many bits (radio) the RD contains

16 D,128

NO.61 What designs in the router can improve the reliability of the router?

Dual power supply design

Module hot-swappable design

Issu Design

Dual-engine design

NO.62 After configuring the VLAN-based MAC address drift detection function, if the MAC address drifts, you can configure the actions of the interface according to your needs.
Which of the following is not a configurable action?

Send an alert

The MAC address blocks

Interface blocking

Traffic filtering

NO.63 IGMP SSMMapping is bound to multicast through a static multicast source, so that members of IGMPv1 and IGMP2 can also access the SSM multicast network. The following statement about IGMPSSMMapping is wrong? (Radio).

The multicast address of the SSM is 232000~232255255255

IGMP SSM Mapping does not process reporting messages from IGMPv3 In order to ensure that the same network segment runs any version

IGMP hosts can make SSM services run IGMPv3 on the multicast router socket connected to the network segment where the member host is located

If the IGMP SSM Mapping feature is not enabled, neither IGMPv1 nor IGMPv2 supports multicast for deploying SSM modules

NO.64 Use ping-ax-cY-sZ-vpn-instance M 105162, which has the meaning of

IcMP request for the ping, message size Z (without IP and ICMP headers)

The source IP address of the ping packet is X

The ping belongs to the VPN instance M

The ping sends Y ICMP requests

NO.65 Which of the following messages does the BGP protocol support?

Update

Open

Hello

Keepalive

NO.66 Which of the following descriptions of MPLS header TTL are correct?

Copy IPTIL value is handled in such a way that the LSR of the MPLS domain is hidden, which plays a certain security role

Can prevent wireless circular forwarding of messages

MPLS has two ways of handling TTL, one is that the IP packet copies the PTTL of the MPLS header hen it enters the MPLS network Value; Another is to set the TTL of the MPLS header to 255 at the entrance LER

When copying TTL is disabled, tracert can see the LSR of the passing MPLS domain

NO.67 The following statement about VXLAN gateways is incorrect

Layer 2 gateway: Used to solve the problem of tenant access to the VXLAN virtual network, it can also be used for subnet communication of the same VXLAN virtual network.

Layer 3 gateway: Used for cross-subnet communication of VXLAN virtual networks and access to external networks.

VXLAN Layer 3 gateways can be divided into centralized gateways and distributed gateways.

Layer 2 gateway and VPN instance binding.

NO.68 The multicast protocol that can generate multicast distribution trees is?

IGMPv2

BGP

OSPF

PIMV2

NO.69 Auto-negotiate mode is to obtain the maximum interface rate and operating mode, the network administrator configures all Ethernet interface rates of a working switch to 10OMbps, and the operating mode is configured as Full-duplex, when a network card is configured After the auto-negotiate workstation is connected to the switch, the negotiation result is that the interface rate is 10OMbps and the working mode is half-duplex, which of the following explanations is the most reasonable for this phenomenon?

The problem is on the workstation’s NIC, mostly due to the aging of the NIC driver on the workstation, which causes the workstation NIC to learn the interface rate and operating mode configured on the switch

Port rate negotiation is negotiated through the initial port sending FLP, and the operating mode is not negotiated through FLP

STP initializes the port into the blocking state, causing auto-negotiation to fail, so the port should be configured as an edge port

At higher port rates and operating modes, the workstation’s network interface card cannot be configured as auto-negotiate

Auto-negotiation is not configured on the switch, resulting in the switch not being able to send FLP messages to the workstation, causing the workstation to set its own operating mode to Half-duple

NO.70 Regarding the domain-authentication-mode md5 hello command in the ISIS process, the correct explanation is?

ISIS authentication cannot be applied in IPv6 environments.

This command is mainly used to make is the ISIS Hello message carry authentication information during the transmission process.

All router domain authentication methods of the same routing domain are MD5, the password is hello, and lS-IS SNP and LSP will spread normally.

outing domain authentication is primarily used to allow level-1 and Level-2 SNP and LSP messages to carry authentication information during delivery.

NO.71 The following description is correct regarding route control

IBGP routes can be introduced using the impot-route BGP command

AS-path-fiter is for AS-path, which affects the routing of paths.

OSPF, ISIS, and BGP can issue default routes.

In Node 10, if-match community-fiter1 and f-match as-pah-fiter1 are “and the relationship

NO.72 With an existing network running OSPF, what types of LSAs cause ISPF operations?

2?LSA

3?LSA

1?LSA

5?LSA

4?LSA

NO.73 When deploying the ISIS protocol in an IPv6 environment, the following statement is correct (single choice).

By default, the DIS priority for broadcast network interfaces at Level-1 and Level-2 is 1

In broadcast networks, IPv4 and. The DIS priority for IPv6 can be set separately

In the same broadcast network. If each router supports both IPv4 and IPv6. The DIS for IPv4 and IPv6 must be the same device

IS-IS is configured under the finger port is ISIS silent, this interface will not send ISIS packets, but will receive ISIS packets

NO.74 There is an existing switch running the RSTP protocol. If the network topology changes, what happens to the Layer 2 forwarding table that is automatically learned by the switch?

All table entries are dropped

Except for the table entry related to the edge port that is not deleted, all other table entries are deleted

Only table entries related to the port that received the TC message are dropped

If the aging time is set to 15 seconds, entries that exceed the aging time are deleted

Table entries are dropped except for table entries related to edge ports and table entries related to ports that receive TC messages

NO.75 ?? Route? Policy??:ip community-filter Ipermit 100: 1 ip as-path-filter 2 permit ^I00$ route-policy test permit node 10 if-match communityfilter 1 if-match as-path-filter 2 apply as-path 200 Is the above configuration description correct?

The BGP route matches the above only if the BGP route carries a community attribute value of 100:1 or if the AS PATH is 100 route one policy. The AS-one PATH attribute that matches the route is changed to 200

The BGP route matches the above only if the BGP route carries a community attribute value of 100:1 and the AS-One PATH is 100 route policy?. The AS-PATH nature of the matching route is changed to 200

Only if the BGP route carries an AS-PATH of 100, the BGP route matches the route one policy above. The AS-one PATH attribute that matches the route is changed to 200

As long as the BGP route carries a community attribute value of 100:1, the BGP route matches the route-policy above. The AS-PATH attribute of the matching route is changed to 200

NO.76 Huawei’s two switches SWA and SWB are connected together by 7 Ethernet cables, and static link clustering is configured, and the corresponding port on the switch SWA is Ethernet 1/0/1?Ethernet1/0/2?Ethernet 1/0/3?Ethernet 1/0/4?Ethernet 1/0/5, Ethernet1/0/6, Ethernet 1/0/7, configured in order of port if the switch SWA, SWB supports only 6 ports per aggregation group

In the case of consistent configuration of each port, Ethernet 1/0/6 port is an aggregate group Unselected port

In the case of consistent configuration of each port, the Ethernet1/0/1 port is an aggregate group Unselected port

With the same configuration of each port, the Ethernet 1/0/7 port is the aggregate group Unselecte port

With the same configuration of each port, SWA randomly selects one of the 7 ports as the aggregate group Unselecte port

NO.77 Configure queue-based traffic shaping, which defaults to tailing if the queue length exceeds the cache size

True

False
