질문 # 108
Which two types of tunnels are able to be created on all Junos devices? (Choose two.)
정답：A,C
설명：
GRE tunnels can be created on all Junos devices. GRE is a tunneling protocol that encapsulates a wide variety of network layer protocols inside virtual point-to-point links.
IP-IP tunnels can also be created on all Junos devices. IP-IP tunneling is used to encapsulate IP packets within IP packets, providing a simple way to tunnel IP traffic.
질문 # 109
Which two statements are correct about generated routes? (Choose two.)
정답：A,B
설명：
A is correct because generated routes require a contributing route. A contributing route is a route that matches the destination prefix of the generated route and has a valid next hop. A generated route is only installed in the routing table if there is at least one contributing route available. This ensures that the generated route is reachable and useful. If there is no contributing route, the generated route is not added to the routing table.
B is correct because generated routes show a next hop in the routing table. A generated route inherits the next hop of its primary contributing route, which is the most preferred route among all the contributing routes. The next hop of the generated route can be either an IP address or an interface name, depending on the type of the contributing route. The next hop of the generated route can also be modified by a routing policy.
질문 # 110
Referring to the exhibit, all users connected to the same VLAN can communicate with each other, but not with users on other VLANs in this network.
What must be configured to enable communication between the VLANs?
정답：A
질문 # 111
A GRE tunnel is experiencing fragmentation issues. You confirm that the tunnel is up and is functioning correctly. You confirm that hosts are sending 1500-byte packets. In this scenario, which statement is correct?
정답：C
설명：
GRE encapsulation adds a fixed 24 bytes of overhead to every packet it carries -- 4 bytes for the GRE header itself and 20 bytes for the new outer IPv4 delivery header. When a host transmits a full 1500-byte Ethernet payload into a gr- interface, the resulting encapsulated packet becomes
1524 bytes, which exceeds the physical interface's standard 1500-byte MTU and forces fragmentation or drops if the don't-fragment bit is set. The correct remediation is to reduce the effective MTU seen by end hosts so that encapsulated packets never exceed the physical link's transmission limit. Junos automatically applies this logic to gr-logical interfaces, which default to a
1476-byte protocol MTU (1500 minus 24), but when the underlying physical interface or a manually configured path is involved, administrators must explicitly size the interface MTU to
1476 bytes to prevent post-encapsulation oversize packets. Allowing fragmentation with clear- dont-fragment is a workaround that increases CPU load and can degrade performance rather than solving the root cause, BFD addresses link-failure detection rather than MTU sizing, and ToS copying affects only the type-of-service byte, not packet length.
질문 # 112
You are deploying an EX Series switch with a Wi-Fi access point. The access point needs all untagged traffic to use a specific VLAN. In this scenario, which feature should you enable on the switch port?
정답：C
