Begin to Test:

1. The OSPF protocol runs between CE and PE, when CE1 advertises the route of the site to CE2. Which of the following description is wrong?

When PE2 receives a BGP route from PE1 that carries a different Domain ID from the local one, it is correct for all LSAs, and PE2 will generate Type5 LSA or Type7 LSA

When PE2 receives the same Domain ID as the local BGP route sent by PE1, PE2 will generate Type3 LSA for Type1 LSA and Type2 LSA

When PE2 receives the same Domain ID as the local BGP route sent by PE1, for Type3 LSA, PE2 will generate Type5 LSA

The Domain ID configured by PE1 can be used as an extended community attribute of BGP and sent along with the route to PE2.

Question 1 of 25

2. By default, which of the following secure MAC address types will be lost after the device restarts?

Question 2 of 25

3. Regarding MP-BGP, whici of the following description is incorrect?

MP-BGP's message type and VPNv4 routing policy are the same as BGP-4

MP-BGP needs to assign private network labels to VPNv4 routes

MP-BGP advertises VPNv4 routes through two attributes: MP_REACH_NLRI and MP_UREACH_NLRI

Question 10 of 25

11. 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 11 of 25

12. 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 12 of 25

13. 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 14 of 25

15. In an intra-domain MPLS VPN network, when a data packet enters the public network and is forwarded, it will be encapsulated with two layers of MPLS labels. Which of the following description is wrong about the two layers of labels? (Multiple choice)

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.

By default, the outer label is ejected before the packet is forwarded to the last-hop device

The outer label of MPLS VPN is called the private network label. The inner label is called the public network label.

The outer label is used to correctly send the data packet to the corresponding VPN on the PE device

To support the processing and calculation of IPv6 routing, IS-IS added NLPID to 129 TLV

IS-IS working at the data link layer only needs to add a new TLV to support Pv6

To support the processing and calculation of IPv6 routes, IS-IS has added TLV232236

By default, IS-IS enables the multi-topology feature
