Question 62
R1 executes the operation ping -a 10.1.1.1 10.5.16.2, what does this command mean?
The source IP address of the ping packet is any directly connected port address of R1
The source IFP address of the ping packet is the outgoing interface address of the optimal IP route that R1 points to 10.5.16.2, and is not 10.1.1.1
The source IP address of the ping packet is 10.1.1.1
The destination IP address of the ping packet is 10.1.1.1 and 10.5.16.2
Question 63
Regarding the role of ping and tracert, which of the following statements is correct?
Ping detects the two-way reachability between the correct end and the one-way icmp echo request packet
Tracert must be able to trace every hop IP address from source to destination
Ping verifies the reachability from the local end to the opposite end, it does not mean that the opposite end is reachable from the local end
Tracert has the same function as ping, but the name is different
Question 64
In the intra-domain MPLS VPN network, when the data packet enters the public network and is forwarded, it will be encapsulated with two layers of MPLS labels. Regarding the description of the two layers of labels, which of the following options is wrong?
The outer label of MPLS VPN is allocated by the LDP protocol or statically, and the inner label is allocated by the MP-BGP neighbor at the correct end.
The outer label of MPLS VPNE is called the private network label, and the inner label is called the public network label.
By default, the outer label is singled out before the packet is forwarded to the last hop device
The outer label is used to correctly send the data packet to the corresponding VPN on the PE device
Question 65
