A : Type3

B : Type2

C : Type4

D : Type1

Answer: B

Question 2

The following statement about static VXLAN tunnel configuration is correct?

Options :

A : A BD needs to create an NVE country, and when there are multiple BDs, multiple NVE interfaces must be created

B : An NVE interface can be associated with multiple VNls, so you can create only one NVE interface when there are multiple BDs

C : For a VXLAN tunnel, you need to create a corresponding NVE interface, in which you explicitly specify the source IP address and the destination IP address , so there are multiple VXLAN tunnels on the VTEP that must be vE interfaces The destination address of the VXLAN tunnel is specified in the

D : NVE interface, and multiple VXLAN tunnels can create only one NVE interface

Answer: D

Question 3

The following statement about the VPNv4 address is wrongly described as ?

Options :

A : By default, PE does not perform VPN-target filtering on received VPNv4 routes.

B : Local PE sets up An Export Target for these routes before releasing VPNv4 routes learned from sites that are directly connected to them to other PEEs attributes, and are published with routes as extended community attributes for BGP.

C : Carries the RD attribute when BGP publishes both reachable and unreachable VPNv4 routes.

D : The VPNv4 address has a total of 12 bytes, including an 8-byte route identifier RD (Route Distingulisher) and a 4-byte IPv4 Address prefix.

Answer: A

Question 4

In different scenarios, RSTP provides different protection functions, and the wrong statement about this statement is

Options :

A : The root protection feature is enabled for the specified port, and its port role can only remain as the specified port

B : When the anti-TC-BPDU packet attack feature is enabled, the number of times the switching device processes IC BPDU packets per unit time is configurable

C : after the BPDU protection function is enabled on the switching device, if the edge port receives RST BPDU, the edge port will be set to a non-remote port and the spanning tree calculation will be re-performed

D : Start the specified port of root protection, when the port receives a better RSTBPDU, the port will enter the Discarding state and is no longer forwarding packets. If the port does not receive a better RSTBPD for a period of time then automatically revert to the normal Forwarding state

Answer: C

Question 5

Both the CSNP packet of ISlS and the DD packet of OSPF have a role in the MA network, describing the role

of the link state database summary, which is correct compared to the following statements of these two types

of messages

Options :

A :

Both packets need to be confirmed to the terminal router after being sent, otherwise they need to be

retransmitted

B : Once the adjacency relationship is established, the CSRP packet and the D message will stop sending

C : The two packets do not need to be confirmed to the router after they are sent the master-slave relationship in the DD message interaction of

D : OSPF is not identity bound to dr/BDR; the CSN message is generated only by DIS

Answer: D
