On an RSTP network , port roles are optimized to overcome the disadvantages of STP . Which of the following port roles are supported in RSTP ?
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?
IGMP snooping enables a switch working at Layer 3 to establish a Layer 3 multicast forwarding table by listening to IGMP messages exchanged between the upstream Layer 3 device and the user hosts. The switch working at Layer 3 manages and controls the forwarding of multicast data packets based on the Layer 3 multicast forwarding table, thus suppressing multicast data flooding on the Layer 3 network.
When multiple access channels are set for the same access requirement, the insecure access channels are not used and secure access channels are selected in normal cases. Which of the following are secure access channels?
There are two types of BGP peer relationships : EBGP and IBGP . When configuring EBGP, ensure that the peer IP address is routable and the UDP connection can be correctly established.
BGP is generally applied to complex networks where routes change frequently. Frequent route flapping consumes a large number of bandwidth and CPU resources, and even affects the normal operation of the network. This is an unavoidable problem that cannot be solved in BGP.
In special scenarios, when advertising routes to an IBGP peer, a BGP device needs to set the next hop to its IP address to prevent blackhole routes. Which of the following commands can be run in this case?
A local router runs IS-IS and its command output is shown in the following figure. Which of the following statements is true?
On a WLAN, the HSB service sets up an HSB channel between two devices that back up each other, maintains the channel status, and backs up data. Which of the following can HSB back up in real time?
On an OSPF network, an IR in area 0 must be a BR, but an ASBR may not be an ABR.
