質問 # 44

Click the Exhibit button.
Which two statements are correct about the class-of-service configuration shown in the exhibit? (Choose two.)

A. Incoming traffic will not be classified because no classifier exists in the configuration.
B. The best-effort queue can never transmit more than 40% of the total bandwidth on the ge-0/0/0 interface, even if that bandwidth is available.
C. The best-effort queue can transmit more than 40% of the total bandwidth on the ge-0/0/0 interface, if no other queue is using that bandwidth.
D. Incoming traffic will be classified using the default classifier.

正解：A、C

解説：
The class-of-service (CoS) configuration in the exhibit shows how traffic is scheduled on the ge-0/0/0 interface. Let's analyze each statement to determine its correctness:
A: Incoming traffic will not be classified because no classifier exists in the configuration.
* This statement is correct. The configuration shown does not include any classifier, so no explicit classification is defined. As a result, incoming traffic will not be classified according to any custom criteria.
B: The best-effort queue can transmit more than 40% of the total bandwidth on the ge-0/0/0 interface, if no other queue is using that bandwidth.
* This statement is correct. The transmit-rate percent 40 means that 40% of the bandwidth is guaranteed for the best-effort queue, but it can use more bandwidth if other queues (like the priority scheduler) are not utilizing their allocated bandwidth.
C: Incoming traffic will be classified using the default classifier.
* This statement is incorrect. Without an explicit classifier in the configuration, there is no mention of a default classifier being used. Therefore, the incoming traffic won't be classified based on the configuration shown.
D: The best-effort queue can never transmit more than 40% of the total bandwidth on the ge-0/0/0 interface, even if that bandwidth is available.
* This statement is incorrect. The transmit-rate percent 40 sets a guaranteed minimum bandwidth but does not set a maximum limit. The best-effort queue can utilize more bandwidth if other queues are not using their allocated portions.

質問 # 45
In which two ways does OSPF prevent routing loops in multi-area networks? (Choose two.)

A. The SPF algorithm prunes looped paths within an area.
B. All areas are required to connect to area 0.
C. The LFA algorithm prunes all looped paths within an area.
D. All areas are required to connect as a full mesh.

正解：A、B

解説：
OSPF is an interior gateway protocol that uses link-state routing to exchange routing information among routers within a single autonomous system. OSPF prevents routing loops in multi-area networks by using two methods: area hierarchy and SPF algorithm. Area hierarchy is the concept of dividing a large OSPF network into smaller areas that are connected to a backbone area (area 0). This reduces the amount of routing information that each router has to store and process, and also limits the scope of link-state updates within each area. All areas are required to connect to area 0 either directly or through virtual links2. SPF algorithm is the method that OSPF uses to calculate the shortest path to each destination in the network based on link-state information. The SPF algorithm runs on each router and builds a shortest-path tree that represents the topology of the network from the router's perspective. The SPF algorithm prunes looped paths within an area by choosing only one best path for each destination3.

質問 # 46
In IS-IS, which two statements are correct about the designated intermediate system (DIS) on a multi-access network segment? (Choose two)

A. A router with a priority of 10 wins the DIS election over a router with a priority of 1.
B. On the multi-access network, each router forms an adjacency to every other router on the segment
C. A router with a priority of 1 wins the DIS election over a router with a priority of 10.
D. On the multi-access network, each router only forms an adjacency to the DIS.

正解：A、B

解説：
Option A (Correct):
* In IS-IS, the Designated Intermediate System (DIS) is elected based on the highest configured priority (as defined in Junos OS).
* If priorities are equal, the router with the highest MAC address becomes the DIS.
* A priority value of 10 will always override a lower priority (e.g., 1).

Exhibit

You want to use both links between R1 and R2 Because of the bandwidth difference between the two links, you must ensure that the links are used as much as possible.
Which action will accomplish this goal?

A. Define a policy to tag routes with the appropriate bandwidth community.
B. Disable multipath.
C. Enable per-prefix load balancing.
D. Ensure that the metric-out parameter on the Gigabit Ethernet interface is higher than the 10 Gigibit Ethernet interface.

正解：A

質問 # 48
Which two statements are correct about IS-IS interfaces? (Choose two.)

A. If a point-to-point interface is in both L1 and L2, separate hello messages are sent for each level.
B. If a broadcast interface is in both L1 and L2, one combined hello message is sent for both levels.
C. If a point-to-point interface is in both 11 and L2, one combined hello message is sent for both levels.
D. If a broadcast interface is in both L1 and L2, separate hello messages are sent for each level.

正解：C、D

解説：
Intermediate System to Intermediate System (IS-IS) is a link-state routing protocol that supports Level 1 (L1), Level 2 (L2), or both (L1/L2) operations. The way IS-IS sends Hello (IIH) packets depends on whether the interface is point-to-point (P2P) or broadcast (LAN).
Evaluating the Answer Choices
✅ Option A: "If a point-to-point interface is in both L1 and L2, separate hello messages are sent for each level." Incorrect!
On point-to-point (P2P) interfaces, only one combined Hello message is sent for both L1 and L2.
IS-IS P2P Hellos include both Level 1 and Level 2 TLVs in the same message.
Reference:
❌ This statement is incorrect.
✅ Option B: "If a point-to-point interface is in both L1 and L2, one combined hello message is sent for both levels." Correct!
On point-to-point (P2P) links, IS-IS sends a single Hello message that includes TLVs for both L1 and L2.
This reduces overhead and simplifies adjacency formation.
✅ This statement is correct.
✅ Option C: "If a broadcast interface is in both L1 and L2, separate hello messages are sent for each level." Correct!
On broadcast (LAN) interfaces, IS-IS sends separate Hello messages for L1 and L2.
This is because L1 and L2 use separate Designated IS (DIS) elections and different multicast addresses:
L1 Hellos: Sent to AllL1IS (01:80:C2:00:00:14)
L2 Hellos: Sent to AllL2IS (01:80:C2:00:00:15)
✅ This statement is correct.
✅ Option D: "If a broadcast interface is in both L1 and L2, one combined hello message is sent for both levels." Incorrect!
As stated above, IS-IS sends separate Hello messages for L1 and L2 on broadcast interfaces because they have independent DIS elections.
❌ This statement is incorrect.
Final answer:
✅ B. If a point-to-point interface is in both L1 and L2, one combined hello message is sent for both levels.
✅ C. If a broadcast interface is in both L1 and L2, separate hello messages are sent for each level.
Verification from Juniper Documentation
Juniper IS-IS Configuration Guide confirms:
Point-to-Point (P2P) interfaces send one combined Hello for both levels.
Broadcast interfaces send separate L1 and L2 Hellos due to separate DIS elections.
RFC 1195 (IS-IS Extensions for IPv4) specifies that broadcast networks require distinct Hellos per level.
