Question List

Question1: Two routers configured to run BGP have been connected to a firewall, one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer, including the correct BGP session endpoint addresses and the correct BGP session hop-count limit (EBGP multihop). What is a good first test to see if BGP will work across the firewall?

Question2: Which of the following scenarios can an AS-path-filter be used for? (Multiple Choice)

Question3: Which of the following statements about penultimate hop popping are true?

Question4: Which of the following are functions of Random Early Discard (RED)?

Question5: Which of the following are found in a basic Network Layer Packet? (Multiple Choice.)

Question6: On a BGP/MPLS Ipv4 VPN, OSPF, LDP, and static routes are configured. Which of the following protocols must be enabled with GR to achieve NSF on PEs? (Multiple Choice)

Question7: Which of the following statements is true about the port mirroring on Huawei devices?

Question8: Which parameter will not be received from the root bridge by a non-root bridge running 802.1D STP?

Question9: Switches use IPSG to verify the source address of IP packets. IPSG obtains the binding table by listening to the address resolution process.

Question10: The LS Sequence Number field is used to detect expired and duplicate LSAs. This field is a signed 32-bit integer and therefore the minimum LS Sequence Number is 0x800000000.

Question11: Which of the following are legal representations of the IPv6 prefix 12AB00000000CD30? (Multiple Choice)

Question12: Which of the following statements are true about RIPng? (Multiple Choice)

Question13: When a router within the HW network makes a forwarding decision, the _____is always used to select the best route from those installed in the routing table.

Question14:
Based on the preceding networking and configurations, which of the following statements is true?

Question15: What is the destination IP address of routing update packets sent by RIPv2?

Question16: In a data communication session between two hosts, the session layer in the OSI model generally communicates with what other layer of the OSI model?

Question18: Which of following statements is true about IS-IS LDP synchronization?

Question19: Which of the following statements is false about the DSCP field?

Question20: Routers HW1 and HW2 are IP Multicast routers. These routers use (S, G) entries for multicast packet forwarding. Which of the following address types are used in the "S" entry?

Question21: Which of the following are key differences between RIP version 1 and RIP version 2? (Multiple Choice)

Question22: Based on the routing information exchange mode, MPLS VPNs are usually classified into two types. One is the overlay VPN. What is the other type of MPLS VPN?

Question23: When a router is building a routing table from different routing protocols, which of the following will determine the routes to be installed in the routing table?

Question24: Authentication can be configured in the IS-IS protocol to enhance IS-IS security. The IS-IS authentication functions include interface authentication, area authentication, and routing domain authentication.

Question25: To improve delay and jitter on frame relay links, we can fragment and assemble the frame between multiple PVCs. This is similar to what happens with PPP multilink.

Question26: Besides an IPv4 address, a router distinguisher (RD) also contains an identifier that distinguishes IP routes to the same destination IP address in different VPNs. How many bits are there in the identifier?

Question27: As shown in the following figure, the neighbor relationship between R1 and R2 has just been established.
Which of the following statements is true about the database synchronization process between R1 and R2?

Question28: Which of the following are used in Ethernet networks? (Multiple Choice)

Question29: You must ensure that mission critical traffic is prioritized in the HW network. The IP precedence of a packet can be determined by which of the following?

Question30: If a Gigabit Ethernet port receive buffer becomes full on a LAN switch, what protocol can be used to request that the remote port delay sending frames for a specified time?

Question31: OSPF is running on a network. In OSPF, what LSA type would only cause an Incremental SPF calculation? (Multiple Choice)
