A. Type 5 LSAs are advertised by ASBRs and flooded on OSPF networks except stub areas and NSSAs. B. Filtering policies can be configured on ABRs or ASBRs to filter Type 5 LSAs. C. Routers in the same area as the ASBR can calculate external routes through intra-area LSAs and Type 5 LSAs. D. A Type 5 LSA contains the FA address, which is 0.0.0.0.The FA address is reserved only and does not take effect.

A. HTTPS TCP 443 protocol acknowledgment use port B. When using a website HTTPS, when accessing, if the user cannot browse the digital user of the website, access the website. C. If the traffic contains a virus, the router cannot use the virus to directly detect the HTTPS, IPS detection. D. HTTPS SSL VPN Pass Used to secure access to data.

A. LDP FRR can generate an LSP as the backup of the primary L5P based on Label Mapping messages that are not from the optimal next hop. LDP FRR establishes forwarding entries for the backup LSP. B. Synchronization between LDP and IGP requires suppression of IGP route advertisement to achieve consistent LDP and IGP. C. LDP Graceful Restart (GR) leverages the separation of the forwarding plane and control plane by MPLS to ensure uninterrupted traffic transmission during a protocol restart or active/standby switchover. D. By default, the policy for manually configuring LDP FRR specifies that backup routes with 32-bit addresses should trigger the setup of a backup LDP L5P.

A. Interchange of the Instance VLAN mapping configuration is inconsistent B. Interchange of the exchange C. Interchange of the exchange The Region Name configuration is inconsistent D. The exchange between the BPDUs is inconsistent.

A. Sliding window size can only increase or remain unchanged B. Sending the transmission end does not require a full window size C. TCP Sliding window allows multiple packets to be sent before receiving the acknowledgment D. When the repeater is over-timed, the sender does not receive the confirmation, and the data will be unrecognized. E. The sender announces the initial window size

A. Chain bandwidth road is not enough B. Chain layer protocol road inconsistency C. The IP address is not on the same network segment. D. Subnet mask does not match code

The registration text is used to construct the source tree to report the DR RP RPT with it. D. Registration The package encapsulates the datagram group service.

A. Advanced ACL route-policy, which can be used in the routing line. B. Entry permit:0 less-equal 128 IPv6 means that all routes are allowed to pass. C. If more than one point Route-policy is specified, the matching pattern of at least one of the points in the permit section is the section should be D. Route-Policy can only filter by default route

A. If a previous Link-LSA Prefix Option 0x00 Prefix IPv6 suffix field is , then it will not be admitted to the single calculation. B. Option LSA Link-lsa field exists in the header, not the data area C. Contains both the local address chain of this interface and all the pre-IPv6 suffixes of this interface. D. Contains both the local address chain of this interface and all the previous Ipv6 suffixes in the same area on the router.
