Source-Specific Multicast (SSM)is being used throughout the HW IP Multicast network. Which of the following three
statements about SSM are true? (Choose three.)
A. SSM uses Shortest-Path Trees Only
B. There are no RPs to worry about
C. SSM is best suited for applications that are of the Many-to-Many category
D. SSM uses shared Trees only
E. The use of SSM is recommended when there are many sources and it is desirable to keep the amount of route
state in the routers in the network to a minimum.
F. SSM is best suited for applications that are of the one-to-many category
Regarding the logical model of the MPLS TTL pair, is the following description correct?
A. Pipe IP MPLS IP TTL 1 In MPLS TTL mode, when the message passes through the network, it is mapped to the field
at the ingress point.
B. MPLS TTL IP TTL MPLS A label, which has the same function as the header, can prevent the network from routing
the loop (as it is)
C. Uniform IP MPLS IP TTL 1 MPLS TTL mode is simulated. When the message passes through the network, the entry
point is reduced and the field is fixed to the value.
D. In the case of the MPLS VPN MPLS Ingress uniform, the private network text can be used in the reporting mode.
HW has a Frame Relay network with two sites (a headquarters site and a remote site) connected by a single PVC. RIP
version 2 is running in the network. A new remote site is added and HW has ordered a second PVC between this site
and the headquarters site. All Frame Relay interface IP addresses are in a single subnet.
The customer configured Frame Relay DLCI mappings and can successfully ping from the new remote to the headquarters site as well as to the other remote site. However, the new router does not have a route in its route table to the other remote site\’s LAN, and cannot ping the LAN interface or any hosts on that LAN.
What is most likely causing the problem?
A. Triggered updates should be configured on the headquarters router, to directly forward routing updates between the two remote sites
B. The headquarters site router has split-horizon enabled on the frame-relay interface
C. Neighbor statements are not configured on the two remote sites, pointing to all other sites
D. The frame-relay IP to DLCI mappings are incorrectly configured
E. RIP cannot propagate routing updates over a partial mesh frame-relay configuration, so another routing protocol
should be selected
Synchronization between LDP and IGP suppresses reachable IGP route advertisement to implement network
convergence and ensure LDP and IGP are along the same path. This minimizes traffic loss and improves network
As shown in the figure, the R1 R2 ISIS R1 R2 ? neighbor relationship is established, and the data synchronization
the process with it is correct.
A. The message sent by the R1 R2 PSNP is a message.
B. The message sent by R1 R2 CSNP is a message.
C. The message sent by the R1 R2 LSP is a packet.
D. The message sent by R1 R2 Hello is the message.
The configurations of two routers in a company are shown. Which of the following statements regarding the routing table of R1 is true?
A. The IP routing entries whose destination network segment is 10.0.2.2/32 on R1 can be generated through OSPF only
when the IS-IS preference of R2 is changed to 5
B. If the IS-IS preference of R1 is changed of R1 is changed to 5, the IP routing entries whose destination network
the segment is 10.0.2.2/32 on R1 are generated through OSPF
C. If the IS-IS preference of R1 is changed to 5, the IP routing entries whose destination network segment is 10.0.2.2/32
on R1 are generated through IS-IS
D. If the IS-IS preference of R2 is changed to 5, the IP routing entries whose destination network segment is 10.0.2.2/32
on R1 are generated through IS-IS
Which of the following are key differences between RIP version 1 and RIP version 2? (Multiple Choice)
A. RIP version 2 uses multicasts while RIP version 1 does not
B. RIP version 1 supports authentication while RIP version 2 does not
C. RIP version 1 does not support VLSM while RIP version 2 does
D. RIP version 1 is distance vector while RIP version 2 is not
E. RIP version 1 uses hop counts as the metric while RIP version 2 uses bandwidth information
Routers and routers are running. Both routers are in R1 R2 BGP AS 65234 R2 R1 BGP. The router\\’s route
exists on the router\\’s path.
By the table, but not in the router\\’s routing table. R1 IP So what caused the problem?
A. Synchronization is turned off
B. BGP Down neighbor relationship
C. Router is not enabled R1 BGP Multi-hop
D. Routing is not the best
In the shared network, which mechanism is used to prevent duplicate traffic PIM-SM?
A. Register mechanism
B. BSR/RP mechanism
C. Assert mechanism
D. Join/Prune mechanism
LAND\\’s attack means that the attacker sends a source address and a destination address to the target host. The target is marked as the source port and the destination port. SYN-ACK TCP report text, the receiving end is waiting for the sending end of the final message, and the connection is always connected in a semi-connected state, causing the
receiver to receive limited resources. Waste
In a basic network packet layer, which information can be included (more?)
A. Data Road Department Chain Head
B. Upper data layer
C. Network Department
D. Path record
E. net tail layer
One of the VXLAN BD VNIs can have multiple correspondences
An OSPF router is connected to Area 0 and Area 1, and Area 1 is configured as a stub area. Which type of LSAs are in
A. Type 1, Type 2, and Type 5 LSAs
B. Type 1, Type 2, and Type 3 LSAs
C. Type 3 and Type 4 LSAs
D. Type 7 LSA
E. Type 1 and Type 2 LSAs
The correct answer is here:
Q1: ABF, Q2: B, Q3: B, Q4: A, Q5: B, Q6: C, Q7: AC, Q8: B, Q9: C, Q10: B, Q11: BC, Q12: B, Q13: B
