• B. A level 2 IS4S adjacency will form
• C. No IS-IS adjacencies will form
• D. A level 1 and level 2 IS-IS adjacency will form

正解：C
質問 # 43
Click the Exhibit button.

In the exhibit, each IP subnet in the campus environment is associated with a unique VLAN ID.
Which action will ensure that Host C will communicate with Host A and Host B?

• A. Configure a port-based ACL that permits inter-VLAN routing for all configured VLANs
• B. Configure all switch ports connecting to the host devices as trunk ports associated with all VLANs
• C. Configure all switch ports connecting to the host devices as access ports associated with a common VLAN
• D. Configure an IRB interface for each VLAN and associate it with its corresponding VLAN

正解：D
質問 # 44
By default, how long will a learned MAC address be retained in the bridge table on an EX Series switch?

• A. 600 seconds
• B. 3600 seconds
• C. 300 seconds
• D. 1800 seconds

正解：C
質問 # 45
Router-1 and Router-2 need to connect through the Internet using a tunneling technology.
Hosts that are connected to Router-1 and Router-2 will be sending traffic up to 1500 bytes.
The maximum segment size is supported across the path is 1520 bytes.
Which tunneling technology will allow this communication to take place?

• A. GRE tunnel
• B. IP-IP tunnel
• C. IPsec VPN transport mode
• D. IPsec VPN tunnel mode

正解：B 解説：
Difference Between GRE and IP-IP Tunnel. Generic Routing Encapsulation (GRE) and IP-in-IP
(IPIP) are two rather similar tunneling mechanisms which are often confused. In terms of less
overhead, the GRE header is 24 bytes and an IP header is 20 bytes.
質問 # 46
Which statement is correct about IS-IS link state PDUs?

• A. They are used to maintain link-state database synchronization.
• B. They are used to establish adjacencies.
• C. They are used to determine whether the neighbors are Level 1 or Level 2.
• D. They are used to build the link-state database.

正解：D
