問題 #328
R1, R2, R3, and R4 run IS-IS, and the DIS priorities of their interfaces are shown in the following figure. If all these devices are started simultaneously, will be elected as the DIS. (Enter the device name, for example, R1.)

答案：

解題說明：
R4
* DIS Election in IS-IS:
* In IS-IS, the Designated Intermediate System (DIS) is elected on broadcast networks to reduce the number of LSAs exchanged and maintain the LSDB.
* The DIS is elected based on priority:
* The router with the highest priority is elected as the DIS.
* If priorities are equal, the System ID is used as a tie-breaker, and the router with the highest System ID becomes the DIS.

問題 #329
Which of the following descriptions of the different classifications of PBR is correct?

A. Local PBR is invalid for originating packets and only works for forwarded packets.
B. Interface PBR is called under the interface and takes effect on the outbound packets of the interface.
C. Interface PBR can modify the IP-Precedence of IP packets
D. PBR can be divided into interface PBR, local PBR and routing PBR.

答案：B

問題 #330

問題 #332
Which of the following statements is false about the default processing of the next hop address when a BGP device advertises a route?

A. When advertising a locally originated route to an IBGP peer, a BGP device sets the next hop address to the IP address of its interface connected to the peer.
B. When advertising a route to an EBGP peer, a BGP device sets the next hop address to the IP address of its interface connected to the peer.
C. When advertising a non-labeled route received from an EBGP peer to an IBGP peer, a BGP device changes the next hop address to the IP address of its interface connected to the IBGP peer.
D. A BGP device does not change the next hop address of a route if the route is received from an IBGP peer and is to be sent to another IBGP peer.

答案：C

解題說明：
Comprehensive and Detailed Step-by-Step Explanation:
* Default Next Hop Behavior in BGP:
* Locally Originated Routes (A): The next hop is set to the advertising router's interface IP address.
* Routes Received from EBGP (B): The next hop is not changed when these routes are advertised to IBGP peers. (This makes Option B false.)
* Routes Advertised to EBGP (C): The next hop is set to the interface IP address of the advertising router.
* Routes Advertised Between IBGP Peers (D): The next hop is not modified by default.
* Incorrect Statement:
* Option B is incorrect because the next hop of a non-labeled route received from an EBGP peer is not changed when it is advertised to IBGP peers.
