トピック 1	High Availability: This section of the exam measures the skills of a Data Center Reliability Engineer and covers strategies to ensure continuous network availability. It includes features like Link Aggregation Groups (LAG), Graceful Restart (GR), Bidirectional Forwarding Detection (BFD), and Virtual Chassis. It also provides a basic understanding of how to configure, monitor, and troubleshoot each of these high-availability components to maintain resilient network performance.
トピック 2	Protocol-Independent Routing: This section of the exam measures the skills of a Routing Engineer and covers routing features that function independently of any specific protocol. It includes static, aggregate, and generated routes, along with the concept of martian addresses. Routing instances and Routing Information Base (RIB) groups are introduced, as well as techniques like load balancing and filter-based forwarding. Configuration, monitoring, and troubleshooting aspects of these routing components are also covered in this section.
トピック 3	Data Center Architectures: This section of the exam measures the skills of a Data Center Architect and covers foundational knowledge about various data center designs. It includes traditional multitier architectures as well as more modern IP fabric architectures using spine-leaf topologies. The section also touches on Layer 2 and Layer 3 strategies for forwarding traffic, the differences between overlay and underlay networks, and introduces Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN), explaining its basic purpose and role in data center environments.
トピック 4	Layer 2 Switching and VLANs: This section of the exam measuresthe skills of a Network Support Engineer and covers the essential concepts of Layer 2 switching operations within Junos OS. It includes an overview of Ethernet switching and bridging, providing an understanding of how Layer 2 networks function. The section also introduces VLAN concepts, focusing on port modes, VLAN tagging methods, and the purpose of Integrated Routing and Bridging (IRB). It further explores the practical side by addressing how to configure, monitor, and troubleshoot both Layer 2 switching and VLANs.
トピック 5	Data Center Routing Protocols BGP OSPF: This section of the exam measures skills of a Network Operations Specialist and covers the operation and key concepts of the OSPF protocol. It explains elements such as the link-state database, OSPF packet types, and router IDs, including how adjacencies and designated routers work within areas. The section then transitions to BGP, outlining its basic operations, message types, attributes, and the path selection process. It also discusses both IBGP and EBGP roles. Lastly, the section reviews how to configure, monitor, and troubleshoot OSPF and BGP using routing policies and various tools.

Juniper Data Center, Associate (JNCIA-DC) 認定 JN0-281 試験問題 (Q176-Q181):

質問 # 176
BGP is primarily used for which purpose in a network?

A. Encrypting data traffic between networks
B. Providing Layer 2 connectivity
C. Connecting different autonomous systems and route sharing
D. Internal routing within a single autonomous system

正解：C

質問 # 177
Which statement is correct about member interfaces when creating a LAG?

A. The interface's MTU settings must match on all member interfaces.
B. The interface's duplex settings and link speed must be the same on all member interfaces.
C. Member interfaces must all be allocated on the same chassis when using a Virtual Chassis.
D. Member interfaces must all be allocated on the same PFE.

正解：B

解説：
When creating a LAG (Link Aggregation Group) in Junos, the duplex settings and link speed must be the same across all member interfaces.
Step-by-Step Breakdown:
LAG Overview:
A LAG combines multiple physical interfaces into a single logical interface to increase bandwidth and provide redundancy. All member links must act as a single cohesive unit.
Interface Requirements:
Duplex: All member interfaces must operate in the same duplex mode (either full-duplex or half-duplex). Mismatched duplex settings can cause performance issues, packet drops, or interface errors. Link Speed: All interfaces in the LAG must have the same link speed (e.g., all interfaces must be 1 Gbps or 10 Gbps). Mismatched speeds would prevent the interfaces from functioning correctly within the LAG.
Configuration and Validation: Ensure that all member interfaces have identical settings before adding them to the LAG. These settings can be checked using the show interfaces command, and the LAG can be configured using:
set interfaces ae0 aggregated-ether-options link-speed 10g set interfaces ge-0/0/1 ether-options 802.3ad ae0 Juniper Reference: LAG Configuration: Duplex and link speed must be consistent across member interfaces to ensure proper LAG operation in Juniper devices.

質問 # 178
Referring to the exhibit, which statement is correct?

A. The ge-0/0/12 interfaces is an access port.
B. The ge-0/0/0 interface has been explicitly assigned to a VLAN named default.
C. The asterisk indicates that the interface is active.
D. The default VLAN is a user defined VLAN name.

正解：C

質問 # 179
MACsec provides protection against which two types of threats? (Choose two.)

A. Man-in-the-middle attack
B. Hashing attacks
C. Data decryption
D. Playback attacks

正解：A、D

解説：
MACsec (Media Access Control Security) provides data confidentiality, integrity, and origin authenticity at Layer 2, protecting against several types of threats.
Step-by-Step Breakdown:
Man-in-the-Middle Attack Protection:
MACsec encrypts traffic at Layer 2, preventing man-in-the-middle attacks where an attacker intercepts and manipulates traffic between two communicating devices. Since the data is encrypted, any intercepted packets are unreadable.
Protection Against Playback Attacks:
MACsec also protects against playback attacks by using sequence numbers and timestamps to ensure that old, replayed packets are not accepted by the receiver.
Juniper Reference:
MACsec Configuration: Juniper devices support MACsec for securing Layer 2 communications, ensuring protection against replay and man-in-the-middle attacks in sensitive environments.

質問 # 180
Which statement is correct about IBGP?

A. It ensures that duplicate AS numbers are not present in the AS path.
B. It requires a physical full mesh.
C. It requires a logical full mesh.
D. It ensures that the local and remote peers use different AS numbers.

正解：C

解説：
In IBGP (Internal Border Gateway Protocol), all routers within the same AS (Autonomous System) must have a logical full-mesh topology. This means that every IBGP router must be able to communicate with every other IBGP router directly or indirectly to ensure proper route propagation.
Step-by-Step Breakdown:
Logical Full Mesh:
In an IBGP setup, routers do not re-advertise routes learned from one IBGP peer to another IBGP peer. This rule is in place to prevent routing loops within the AS.
To ensure full route propagation, a logical full mesh is required, meaning every IBGP router must peer with every other IBGP router in the AS. This can be done either directly or via route reflection or confederation.
Physical Full Mesh Not Required:
The physical topology does not need to be a full mesh, but the BGP peering relationships must form a logical full mesh. Techniques like route reflectors or BGP confederations can reduce the need for manual full-mesh peering.
Juniper Reference:
IBGP Configuration: IBGP logical full mesh requirements can be simplified using route reflectors to avoid the complexity of manually configuring many IBGP peers.
