In BGP, the Origin attribute is used to identify the origin of a route. Which of the following statements are true about the Origin attribute?

If a route is imported to BGP by the originator using the network command, the Origin attribute of the BGP route is displayed as i in the BGP routing table.

If multiple routes carry the same destination address but different Origin attributes and all other route selection conditions are the same, BGP selects the optimal route according to the Origin attribute in the following order: IGP > EGP > Incomplete.

This attribute is a well-known mandatory attribute.

If a route is imported to BGP by the originator using the network command, the Origin attribute of the BGP route is displayed as i in the BGP routing table.

If a route is learned through EGP, the Origin attribute of this BGP route is displayed as ? in the BGP routing table.

If multiple routes carry the same destination address but different Origin attributes and all other route selection conditions are the same, BGP selects the optimal route according to the Origin attribute in the following order: IGP > EGP > Incomplete.

This attribute is a well-known mandatory attribute.

A router uses an advanced ACL to filter data. The ACL configuration is shown below. Which of the following statements is false about the configuration?csharpCopyEdit[Huawei] acl 3001[Huawei-acl-adv-3001] rule permit icmp source 192.168.1.3 0 destination 192.168.2.0 0.0.0.255

The ACL permits IP packets from host 192.168.1.3 to network segment 192.168.2.0/24.

The ACL permits ICMP packets from host 192.168.1.3 to host 192.168.2.200.

The ACL denies ICMP packets from host 192.168.1.2 to network segment 192.168.2.0/24.

The ACL permits IP packets from host 192.168.1.3 to network segment 192.168.2.0/24.

The ACL is a numbered ACL whose number is 3001.

A company has a stack consisting of three switches that are running properly. The master switch restarts due to a fault. Given this, which of the following statements are true?

Before the restart of the original master switch is complete, the original standby switch becomes the new master switch.

Before the restart of the original master switch is complete, the original slave switch is specified as the new standby switch.

After the original master switch restarts, it becomes the new master switch.

After the original master switch restarts, the original standby switch becomes a new slave switch.

Before the restart of the original master switch is complete, the original standby switch becomes the new master switch.

On the OSPF network shown in the figure, R1, R2, and R3 run OSPF, and R1 advertises four VPN routes to OSPF. A filter-policy needs to achieve the following goal: R1's and R3's routing tables contain the routes to 192.168.3.0/24, but R2's routing table does not. Which of the following filter-policies cannot meet this requirement?

A filter-policy on R1 for filtering the routes to be imported

A filter-policy on R2 for filtering received routes

A filter-policy on R2 for filtering the routes to be advertised

A filter-policy on R1 for filtering the routes to be imported

A filter-policy on R1 for filtering the imported routes to be advertised

Which of the following statements are true about the packet filtering firewall?

The packet filtering firewall supports per-packet detection.

The packet filtering firewall filters data packets based on ACLs.

The packet filtering firewall can analyze associated packets to improve security.

The packet filtering firewall supports per-packet detection.

The packet filtering firewall can check application-layer data.

The packet filtering firewall filters data packets based on ACLs.

Typically, a protocol that occupies two ports during communication is called a multi-channel protocol. For such protocols, the ASPF function must be enabled on the firewall to ensure smooth setup of the data channel and reduce the risk of attacks. Which of the following protocols is not a multi-channel protocol?

323 (D): A VoIP protocol using multiple channels. Single-Channel Protocol: SMTP (C): A single-channel protocol for email communication, which does not require ASPF.
