질문 # 11
Exhibit

You want to provide better performance for the video traffic that traverses your network The video traffic enters your network without any class-of-service markings According to Juniper Networks, which two classification methods are performed by the routers shown in the exhibit? (Choose two.)

A. R1 performs multifield classification.
B. R2 and R3 perform behavior aggregate classification
C. R2 and R3 perform multifield classification
D. R1 performs behavior aggregate classification.

정답：A,B

설명：
The exhibit illustrates a standard end-to-end Class of Service (CoS) path consisting of an edge router (R1) and core/intermediate routers (R2 and R3).
* Edge Classification (Option B): The scenario specifies that video traffic enters the network without any class-of-service markings. Because there are no DSCP or 802.1p bits to inspect, the ingress router (R1) cannot use simple Behavior Aggregate (BA) classification. Instead, it must use Multifield (MF) classification. MF classification allows the router to look deeper into the packet (Source/Destination IP, Protocol, Port numbers) to identify the video stream and assign it to a specific forwarding class. * Core Classification (Option D): Once R1 has identified the traffic, it will typically apply a rewrite rule on its egress interface to mark the packets with a specific CoS value (like a DSCP code). Consequently, the downstream routers (R2 and R3) do not need to perform expensive deep-packet inspection again. They can use Behavior Aggregate (BA) classification, which simply looks at the markings in the packet header to determine the appropriate forwarding priority.
* Option A and C: These are incorrect because BA classification is impossible on unmarked ingress traffic, and performing MF classification in the core is inefficient and not a recommended Juniper design practice for high-speed transit.

질문 # 12
Click the Exhibit button.

Your network receives the full Internet BGP routing table from two different ISPs. You want your local routers to use Provider A to forward all Internet traffic as long as Provider A is available.
Referring to the exhibit, which two actions would satisfy this requirement? (Choose two.)

A. Use a routing policy to set the local preference attribute value lower for the routes that are learned by R2.
B. Use a routing policy to set the local preference attribute value higher for the routes that are learned by R1.
C. Use a routing policy to set the local preference attribute value lower for the routes that are learned by R1.
D. Use a routing policy to set the local preference attribute value higher for the routes that are learned by R2.

정답：A,D

설명：
To prefer Provider A for all Internet traffic, you should increase the local preference on routes learned from R1 (connected to Provider A) or equivalently decrease the local preference on routes learned from R2 (connected to Provider B). Either approach ensures that your routers select Provider A as the primary path while keeping Provider B as a backup.

질문 # 13
When configuring connectivity to a VoIP enabled phone, which two statements are correct? (Choose two.)

A. The switch places voice traffic in the expedited forwarding class by default.
B. The switch can signal to the phone device which VLAN tag it should use for voice traffic.
C. The switch places voice traffic in the best-effort forwarding class by default.
D. The telephone device can signal to the switch which VLAN tag it will place on voice traffic.

정답：A,B

질문 # 14
Which statement is correct about IS-IS?

A. Level 1 routers route traffic between autonomous systems.
B. Level 2 routers must share the same area address.
C. IS-IS uses areas and an autonomous system.
D. Level 1/2 routers automatically inject a default route to the nearest Level 1 router.

정답：C

질문 # 15
Click the Exhibit button.

Referring to the exhibit, what is required for the BGP peering to establish?

A. Configure neighbor 10.10.10.1 multihop under the ext-peers hierarchy.
B. Configure neighbor 172.16.1.1 multihop under the ext-peers hierarchy.
C. Configure neighbor 172.16.1.1 multipath under the ext-peers hierarchy.
D. Configure neighbor 10.10.20.1 multihop under the ext-peers hierarchy.

정답：B

설명：
Since router1 is using a loopback (192.168.1.1) as its local BGP address, the BGP peer (router2) must establish a session toward this loopback. The remote peer (172.16.1.1) is two hops away, so the multihop option must be configured under the BGP group to allow the TCP session to succeed.
