1. 1A branch LAN must exchange IP traffic with a different network at headquarters. Which component has the primary role of connecting those networks?

   1. A. A wireless access point
   2. B. A Layer 2 switch
   3. C. A router
   4. D. A WLAN controller

   Answer: C

   Explanation: Cisco states, "Switches create a network. Routers connect networks." The branch needs a router to forward traffic between distinct networks.

   Reference: Small Business Networking Resources — What is switch vs. a router?

2. 2A switch port must carry a PC's untagged traffic in existing VLAN 30. Which interface command assigns its access VLAN?

   1. A. switchport access vlan 30
   2. B. switchport trunk native vlan 30
   3. C. switchport voice vlan 30
   4. D. switchport trunk allowed vlan 30

   Answer: A

   Explanation: Cisco lists "switchport access vlan" and explains that it "Assigns the port to a VLAN." Applied to this access port, the command selects VLAN 30.

3. 3A Cisco router's IPv4 routing table shows an entry beginning with code O. Which route source does that code identify?

   1. A. OSPF
   2. B. Static
   3. C. Connected
   4. D. BGP

   Answer: A

   Explanation: Cisco lists "O - OSPF derived" in the show ip route code legend, so O identifies an OSPF route.

   Reference: Cisco IOS IP Routing Protocol-Independent Command Reference: show ip route — show ip route, Examples, code legend

4. 4A network engineer needs a permanent one-to-one mapping from the inside host 10.10.10.1 to the inside global address 172.16.131.1. Which NAT command establishes that mapping?

   1. A. ip nat inside source list 1 pool net-208
   2. B. ip nat inside source static 10.10.10.1 172.16.131.1
   3. C. ip nat pool net-208 172.16.131.1 172.16.131.1 netmask 255.255.255.0
   4. D. ip nat inside source list 1 interface GigabitEthernet0/0 overload

   Answer: B

   Explanation: "Establishes static translation between an inside local address and an inside global address." The static inside source command creates the requested persistent one-to-one translation; the other commands define or use dynamic translation resources.

5. 5A network appliance has an unpatched software weakness that could be used to gain unauthorized access, but no attack has occurred. Which security concept describes the weakness itself?

   1. A. Threat
   2. B. Exploit
   3. C. Vulnerability
   4. D. Mitigation

   Answer: C

   Explanation: "Weakness in an information system, system security procedures, internal controls, or implementation that could be exploited or triggered by a threat source." The weakness is a vulnerability; the other terms describe a potential cause, a means of taking advantage, or a response.

   Reference: NIST CSRC Glossary: Vulnerability — Definitions, FIPS 200 under VULNERABILITY

6. 6A network team uses standardized automation to apply the same router configuration across many sites. Which operational effect should it expect compared with manual per-device changes?

   1. A. More consistent configurations and fewer human errors
   2. B. More varied configurations and fewer human errors
   3. C. More consistent configurations and more human errors
   4. D. More varied configurations and more human errors

   Answer: A

   Explanation: "With the replacement of manual by automated tasks, network devices are configured more consistently and are less prone to human errors." Automation reduces manual variation and associated errors.

7. 7A campus has many wireless access points and needs one component to manage them centrally. Which component fits that role?

   1. A. A Layer 2 switch
   2. B. A WLAN controller
   3. C. A router
   4. D. A wireless client

   Answer: B

   Explanation: Cisco states, "A WLAN controller manages wireless network access points that allow wireless devices to connect to the network." Central AP management is the controller's role.

   Reference: What is a WLAN controller? — What is a WLAN controller?

8. 8A switch access port connects to a Cisco IP phone with a PC behind it. Data already uses VLAN 20; the phone must use VLAN 30 for voice. Which interface command sets the voice VLAN?

   1. A. switchport access vlan 30
   2. B. switchport voice vlan 20
   3. C. switchport voice vlan 30
   4. D. switchport trunk allowed vlan 30

   Answer: C

   Explanation: Cisco says, "You can configure an access port with an attached Cisco IP Phone to use one VLAN for voice traffic and another VLAN for data traffic from a device attached to the phone." Its voice VLAN command is "switchport voice {vlan{vlan-id | dot1p | none | untagged}}". Thus VLAN 30 belongs in the voice command.

9. 9A router has Ethernet0/0 addressed 10.1.1.1/30. Its routing table contains both C 10.1.1.0/30 and L 10.1.1.1/32. What does the L entry represent?

   1. A. The router's own interface address
   2. B. The entire connected subnet
   3. C. A manually configured static route
   4. D. An OSPF-learned destination

   Answer: A

   Explanation: Cisco labels the 10.1.1.1/32 entry L and says, "10.1.1.1/32 is a local host route." It represents the router's own configured interface address.

   Reference: Local Host Routes Installed in the Routing Table on Cisco IOS and Cisco IOS-XR — Cisco IOS Local Routes

10. 10Several inside hosts selected by access list 1 need dynamic translations from the already defined pool net-208. Which command binds the access list to that pool?

    1. A. ip nat inside source static 10.10.10.1 172.16.131.1
    2. B. ip nat pool net-208 172.16.131.1 172.16.131.10 netmask 255.255.255.0
    3. C. ip nat inside source list 1 pool net-208
    4. D. ip nat inside source list 1 interface GigabitEthernet0/0 overload

    Answer: C

    Explanation: "Establishes dynamic source translation, specifying the access list defined in Step 4." The list-to-pool binding selects the inside addresses and assigns pool addresses dynamically.
