Question 272

OSPFv3 is a version of OSPF for IPv6 and is different from OSPFv2. OSPFv3 is based on links but OSPFv2 is based on network segments. Which of the following statements is false?

When an OSPFv3 router obtains routing information from a neighbor, it uses the link-local address of the neighbor as the next hop for packet forwarding.

Two OSPF routers on the same physical link can still establish a neighbor relationship even if no unicast IPv6 address is configured.

Two OSPF routers on the same physical link can still establish a neighbor relationship even if their IPv6 addresses are on different networks.

Except for virtual links, all OSPFv3 interfaces use a link-local address as the destination address of OSPFv3 message.

Question 276

Which of the following statements regarding features of the inter-AS VPN Option C are true?

VPN routes are directly exchanged between the ingress PE and the egress PE, and the routes do not need to be stored or advertised by the intermediate devices.

The inter-AS VPN Option C mode is not applicable to scenarios where multiple Ass are spanned.

A maximum of two labels are required for packet forwarding.

ASBRs do not store VPNv4 routes or advertise VPNv4 routes to each other.

Question 277

Which of the following statements correctly describe the LDP session establishment process?

The label switching router (LSR) with the larger transport address initiates a TCP connection.

After two devices receive a Keepalive message from each other, the LDP session is successfully established.

LDP Neighbor Discovery Hello messages are encapsulated using TCP with the multicast destination address of 224.0.0.2.

After the TCP connection is successfully established, the active party sends an Initialization message to negotiate with the passive party about parameters used for establishing an LDP session.

Question 280

Which of the following statements regarding HTTPS is false?

A router cannot detect the viruses in HTTPS traffic through the IPS technology

HTTPS uses SSL to ensure data security

When a user attempts to visit a website using HTTPS, if the user's browser cannot identify the digital certificate of the website, the user will be unable to access the website

By default, the HTTPS protocol uses TCP port 443
