NO.36 Which of the following is the default interval at which the DIS on a broadcast IS_IS network sends CSNPs.

NO.37 Which of the following statements regarding the stateful inspection firewall is true?

NO.38 ON a stateful inspection Firewall where there is no session table, when the status detection mechanism is enabled and the second packet (CYN+ACK) of 3-way hadshakes reaches the firewall. Which of the following statements is true?

NO.39 The traffic limiting policy feature only supports the number of connections initiated by the specified IP or the number of connections received.

NO.40 Which of the following statements about multicast packet forwarding is true?

NO.41 IGMPV3 not only supports IGMPv1 General Query and IGMPv2 Group-Specific Query, and also IGMPv3 Source/Group-Specific Query.

NO.42 What parameters can a DHCP6 server assign to a DHCPv6 client?

NO.43 Compared with STP, RSTP defines the different port states. Which of the following statements regarding discarding and learning states are true?

NO.44 Compress the 2001:0DBB:B8:0000:C030:0000:0000:09A0:CDEF address.___________(if the answer contains letters, capitalize them.)

NO.45 Which of the following statements regarding an IP prefix are true?

NO.46 When a routing policy is used to filter routes, which of the following route prefixes will be denied by the IP prefix below?

NO.47 See the following figure. RTA, RTB, RTC, and RTD are in the same AS and establish IBGP peer relationships through direct links. RTB an RTC are route reflectors (RRs), RTA and RTC are the RR clients of RTB, and RTB and RTD are the RR clients of RTC. If RTA advertises the route 10.1.1.0/24 to the BGP process, the Originator ID of the BGP route received by RTD is——————.

NO.48 If a router ID is configured in both the system via and the BGP view, BGP uses the router ID configured in the BGP view because the BGP view takes precedence over the system view.

NO.49 Which Of the following IEEE 802.11 standards is also known as Wi-Fi 6?

NO.50 A switch runs MSTP. The configuration is shown in the figure. What is the role of this switch in MSTI 1?

NO.51 To prevent inter-area routing loops, OSPF does not allow advertising routing information between two non-backbone areas and allows sing routing information only within an area or between the backbone area and a non-backbone area. Therefore, each ABR must be connected to the backbone area.

NO.52 When two routers exchange LSDB information using DD packets, a master/slave relationship is formed first, the router with a larger router ID is the master, and determine the MS bit.

NO.53 Which of the following statements regarding the LSA age field are true?

NO.54 Which of the following statements about the forwarding plane of a switch is false?

NO.55 Which of the following TLVs is used by ISIS to describe the IP address of an interface?
