1.

Which of the following statements regarding Local-Preference is true?

Local-Preference is a well-known mandatory attribute. Local-Preference affects traffic that enters an AS. Local-Preference can be transmitted between ASs. The default Local-Preference value is 100.

2.

Which of the following statements regarding AS_Path is false?

AS_Path is a list of ASs that a BGP route passes through. AS_Path is a very important well-known mandatory attribute in BGP. BGP does not accept the routes whose AS_Path attribute contains the local AS number. When a router has two or more routes to the same destination, the router compares the AS_Path attributes of these routes and prefers the route with the longerAS_Path attribute.

3.

Which of the following statements regarding PIM-DM is false?

PIM-DM stands for Protocol Independent Multicast-Dense Mode. It is a dense-mode multicast routing protocol. PIM-DM assumes that each subnet on a network has at least one receiver station interested in the multicast source. PIM-DM uses the graft mechanism to restore multicast packet forwarding proactively. PIM-DM does not have periodic flood-prune processes.

4.

If one routing protocol only needs to import part of the routing information of another routing protocol and set attributes of the imported routes, only the route-policy can meet this requirement.

5.

Which of the following statements regarding join member interfaces are false when link aggregation works in manual mode?

An Eth-Trunk cannot be nestled, and a member interface cannot be an Eth-Trunk. An Ethernet interface can join only one Eth-Trunk. Before adding an Ethernet interface to an Eth-Trunk, ensure that the Ethernet interface does not belong toany other Eth-Trunk. If the local device uses the Eth-Trunk, the remote interface directly connected to the member interface must join the Eth-Trunk so that both ends cancommunicate. An Eth-Trunk can work in Layer 2 or Layer 3 mode. The two working modes can be identified automatically and do not need to be switched manually.

6.

Which of the following statements regarding MUX VLAN is false?

Each group VLAN must be bound to a principal VLAN. If the VLAN ID has been used by the principal VLAN, this VLAN cannot be used for the VLANIF interface, super-VLAN, or sub-VLAN. After MUX VLAN is enabled on an interface, VLAN mapping and VLAN stacking can be configured on the interface. An enterprise can use the principal port to connect to the enterprise server, a separate port to connect to enterprise customers, and a group port to connect toenterprise employees. Enterprise customers and employees can both access enterprise servers, enterprise employees can communicate with each other,
enterprise customers cannot communicate with each other, and enterprise customers and employees cannot communicate with each other.

7.

Single-packet attacks indicate that an attacker controls botnet hosts to send a large number of attack packets, causing link congestion on the attacked network and system resource exhaustion.
