NEW QUESTION 182
What is the correct statement about the difference between OSPFv2 and OSPFv3? (Multiple Choice)

Both OSPFv2 and OSPFv3 support interface authentication, and OSPFv3 authentication is still implemented based on the fields in the OSPF message header

OSPFv3 is similar to OSPFv2 in that it uses a multicast address as the destination address of OSPF packets

OSPFv2 and OSPFv3 have the same types of messages: Hello, DD, LSR, LSU, LSA ack, and their message formats are the same

The protocol number of OSPFv2 in the IPv4 packet header is 89, and the next header number of OSPFv3 in the IPv6 packet header is 89

NEW QUESTION 183
If the PPP link between R1 and R2 is shown, and the direct connection port is not on the same network segment, but the R1 and R2 direct connection ports can communicate, and the Ethernet link cannot communicate under the same IP planning, what is the reason? (Multiple choice)

R1 and R2 are connected to the POS port, and the 24-bit subnet route of the direct connection port of the other party is learned through IPCP.

R1 and R2 are connected to the POS port, and the 32-bit host route of the direct connection port of the other party is learned through IPCP.

The interconnected POS port of R1 and R2 learns the MAC address of the peer interface through LCP, and does not require the ARP request MAC address.

The data packets of the interconnected POS interface of R1 and R2 do not need to encapsulate the Ethernet header, and do not need to use ARP to request the MAC address.

NEW QUESTION 184
Regarding the site in the BGP/MPLS IP VPN network architecture, which of the following descriptions is correct?

In any case, different sites belonging to the same VPN cannot use overlapping address spaces

The two networks that are far apart geographically must belong to different sites

Terminals connected to the operator’s network through the same CE may belong to different sites

A site is a group of IP systems, and a network formed by a host cannot be called a site

NEW QUESTION 185
Which of the following scenarios is not suitable for deploying interface policy routing?

In the scenario of multiple ISP outlets in the corporate network, different network segments of the intranet access the Internet through different ISP outlets

On the core switch, the traffic of mutual access between the internal network and the external network is dragged to the side-mounted security detection device

Modify the next hop of locally originated traffic

On the core switch, draw the traffic from the internal network and external network to the AC device that is connected to the bypass

NEW QUESTION 186
When there are multiple redundant links in an IS-IS network, multiple equal-cost routes may appear.
Regarding equal-cost routes in an IS-IS network, which of the following descriptions is wrong?

When the number of equal-cost routes in the networking is greater than the number configured through commands, and the priorities of these routes are the same, the route with the higher System ID of the next hop device is preferred for load sharing

After the equal-cost routing priority is configured, when the IS-IS device forwards the traffic to the destination network segment, it will not adopt the load sharing method, but will forward the traffic to the next hop with the highest priority.

For each route in the equal-cost route, the priority can be specified, the route with the higher priority will be preferred, and the rest will be used as backup routes

If load sharing is configured, the traffic will be evenly distributed to each link

Internet

DMZ

NEW QUESTION 188
Which type of prefix will the router running BGP advertise to its own IBGP neighbor (assuming the router is not configured as a route reflector)?

The prefix is learned through the EBGP neighbor, or the prefix is learned from the RR.

The prefix is learned by other BGF neighbors, or the prefix is locally learned through network or route introduction.

The prefix is learned by other IBGP neighbors, or the prefix is learned from the EBGP neighbor, or the prefix is learned through the route introduction.

Presences existing in routing shows

The prefix is learned through the EBGP neighbor, or the prefix is learned locally through the network or route.

NEW QUESTION 189

NEW QUESTION 192
Which of the following description about the OSPF virtual link is true?

A virtual connection can be established in any area, and itself belongs to the area after it is established.

The virtual link uses the outbound interface P as the link address.

The virtual link can be used to solve the problem that area 0 is divided.

The cost of the virtual link is the optimal link.

NEW QUESTION 193
Which statement is correct about multicast packet forwarding?

In the multicast transmission mode, the destination address of the message can clarify the location of the receiver

The source address of the multicast packet is a unicast address

RPF check failure indicates that the multicast data packet is received from the sub-optimal interface, but the inbound interface will still receive the multicast traffic and forward it downstream

The IGMP Snooping function cannot control the range of multicast traffic flooding in the Ethernet
