質問 # 188 
Click the Exhibit button.
You are troubleshooting an aggregated Ethernet interface on a Juniper Networks EX Series Switch. The aggregated Ethernet interface does not appear in the output shown in the exhibit.
Which action will solve this problem?
正解：D
解説：
On EX Series switches, aggregated Ethernet (ae) interfaces do not exist by default; before any ae interface can be created, referenced, or brought into service, an administrator must first reserve the desired number of aggregated Ethernet device slots by configuring set chassis aggregated-devices ethernet device-count number at the [edit chassis] hierarchy. This statement allocates the internal resources needed for that many ae interfaces to exist as valid, configurable objects; until it is committed, any interface-level configuration referencing ae0 (such as the aggregated-ether-options and family ethernet-switching stanzas shown in the exhibit) is accepted syntactically by the CLI but never actually instantiates a live ae0 device, which is exactly why show interfaces ae0.0 returns 'device ae0 not found' despite the interface appearing fully configured.
Increasing the device-count to at least 1 (or higher, to cover the number of LAG bundles planned) immediately resolves this and allows ae0 to appear as an operational interface once its member links are also associated with it. This is a foundational and frequently overlooked prerequisite step in LAG deployment on Juniper switches. There is no separate licensing requirement for aggregated Ethernet functionality on EX Series switches, a reboot is not needed since the chassis statement takes effect upon commit, and the LACP mode (active versus passive) is unrelated to whether the ae interface object itself exists in the first place.

質問 # 189
Which statement is correct about the exhibit?
正解：B
質問 # 190
Which two statements describe the purpose of a BGP notification message? (Choose two.)
正解：A、D
解説：
A BGP NOTIFICATION message is one of the four core message types defined in RFC 4271, alongside OPEN, UPDATE, and KEEPALIVE, and it serves a very specific and narrow purpose within the protocol: whenever a BGP speaker detects an unrecoverable, fatal condition in the session -- such as a malformed OPEN message, an unsupported capability, a hold-timer expiration, a finite-state-machine error, or an administratively initiated reset -- it transmits a NOTIFICATION message to its peer immediately before closing the underlying TCP connection and tearing down the session entirely. This confirms that a NOTIFICATION always signals the termination of the session upon a fatal error, never a routine, in-session update. Structurally, every NOTIFICATION message carries a defined error code and error subcode field, which together precisely classify the category and specific nature of the fault that triggered the termination (for example, 'Cease' with a subcode indicating administrative shutdown, or 'Update Message Error' with a subcode indicating a malformed attribute), giving the receiving peer's administrator concrete diagnostic information about exactly why the session was torn down.
Updating route attributes while keeping a session alive is the role of the UPDATE message, not NOTIFICATION, and refreshing a neighbor's table without resetting the session describes the optional Route Refresh capability (a separate, distinct BGP mechanism), neither of which describes NOTIFICATION's function.
質問 # 191
Which statement is correct about the IS-IS ISO NET address?
正解：B
解説：
An ISO NET address is a type of network address used by the IS-IS routing protocol. It identifies a point of connection to the network, such as a router interface, and is also called a Network Service Access Point (NSAP).
An ISO NET address consists of three parts: an area ID, a system ID, and a selector. The area ID identifies the IS-IS area to which the device belongs. The system ID uniquely identifies the device within the area. The selector identifies a specific service or function on the device, such as routing or management.
An ISO NET address must be unique for each device in the network, because it is used by IS-IS to establish adjacencies, exchange routing information, and compute shortest paths. If two devices have the same ISO NET address, they will not be able to communicate with each other or with other devices in the network. Therefore, it is important to assign different ISO NET addresses to each device in the network.
質問 # 192
What are two reasons for creating multiple areas in OSPF? (Choose two.)
正解：B、C
解説：
Option A is correct. Creating multiple areas in OSPF can help to reduce the convergence time .
This is because changes in one area do not affect other areas, so fewer routers need to run the SPF algorithm in response to a change.
Option D is correct. Creating multiple areas in OSPF can help to reduce Link State Advertisement (LSA) flooding across the network. This is because LSAs are not flooded out of their area of origin.
