   Refer to the exhibit. Communication between London and New York is down. Which command set must be applied to resolve this issue?

   • ANewYork(config)#int f0/1 NewYork(config)#switchport nonegotiate NewYork(config)#end NewYork#
   • BNewYork(config)#int f0/1 NewYork(config)#switchport mode trunk NewYork(config)#end NewYork#
   • CNewYork(config)#int f0/1 NewYork(config)#switchport trunk encap dot1q NewYork(config)#end NewYork#
   • DNewYork(config)#int f0/1 NewYork(config)#switchport mode dynamic desirable NewYork(config)#end NewYork#

   Show answer

   Answer: C

   Explanation

   Has to be C. TOS = Trunk Operational Status TAS = Trunk Administrative Status TNS = Trunk Negotiated Status TOT = Trunk Operational Trunk-Encapsulation TAT = Trunk Administrative Trunk-Encapsulation TNT = Trunk Negotiated Trunk-Encapsulation Operational = What we are doing at this moment Administrative = How we configured it Negotiated = What we asked for during the negotiation TAS is configured as Auto, so if other side is trunk and this side is auto then it will form trunk. There is no need for B. If we look for trunk-encapsulation TAT, it's set for ISL. It will not work for .1q. I think you need to change encapsulation to .1q, so answer should be C.

   Refer to the exhibit. The trunk between Gig1/0/1 of switch SW2 and Gig1/0/1 of switch SW1 is not operational. Which action resolves this issue?

   • AConfigure both interfaces to nonegotiate and ensure that the switches are in different VTP domains.
   • BConfigure both interfaces in dynamic auto DTP mode and ensure that the switches are in the same VTP domain.
   • CConfigure both interfaces in dynamic auto DTP mode and ensure that the switches are in different VTP domains.
   • DConfigure both interfaces in dynamic desirable DTP mode and ensure that the switches are in the same VTP domain.

   Show answer

   Answer: D

   Explanation

   The DTP questions are awful. When DTP is in auto it wont be able to negotiate a trunk, therefore, the show int trunk command will produce no output. I still agree, the answer should still be D. DTP needs to be removed from IOS! Utter rubbish and more effort should be put into creating the questions on the subject.

   Select 2

   

   Refer to the exhibit. Which two facts does the device output confirm? (Choose two.)

   • AThe device's HSRP group uses the virtual IP address 10.0.3.242.
   • BThe device is configured with the default HSRP priority.
   • CThe device sends unicast messages to its peers.
   • DThe standby device is configured with the default HSRP priority.
   • EThe device is using the default HSRP hello timer.

   Show answer

   Answer: DE

   Explanation

   D & E is correct! The default priority value is 100. The router in the HSRP group with the highest priority value becomes the active router. The default hold time is 10 seconds for both versions of HSRP (v1 and v2), which is roughly three times the default hello time.

   Refer to the exhibit. Which type of antenna is shown on the radiation patterns?

   • Apatch
   • Bdipole
   • Comnidirectional
   • DYagi

   Show answer

   Answer: B

   Explanation

   Answer is B. Even the pattern shown is a patter of a omnidirectional antena, that pattern is specific of dipole antenas, so making most correct between two

8. Question 158 · 1003 in bank

   Select 2

   

   Refer to the exhibit. All switches are configured with the default port priority value. Which two commands ensure that traffic from PC1 is forwarded over the Gi1/3 trunk port between DSW1 and DSW2? (Choose two.)

   • ADSW2(config)#interface gi1/3
   • BDSW1(config-if)#spanning-tree port-priority 0
   • CDSW2(config-if)#spanning-tree port-priority 128
   • DDSW1(config)#interface gi1/3
   • EDSW2(config-if)#spanning-tree port-priority 16

   Show answer

   Answer: AE

   Explanation

   The correct answers would look to be A & E. Priority is chosen based on the upstream port, therefore we need to make this change on DSW2. This means answers B and D are out. Port priority is set in increments of 16: Switch(config-if)#spanning-tree port-priority ? port priority in increments of 16 This leaves us with C or E. C is the default, so won't change the behaviour here, so it's out too. The only two still standing are A & E.

9. Question 159 · 1003 in bank

   A company has an existing Cisco 5520 HA cluster using SSO. An engineer deploys a new single Cisco Catalyst 9800 WLC to test new features. The engineer successfully configures a mobility tunnel between the 5520 cluster and 9800 WLC. Clients connected to the corporate WLAN roam seamlessly between access points on the 5520 and 9800 WLC. After a failure on the primary 5520 WLC, all WLAN services remain functional; however, clients cannot roam between the 5520 and 9800 controllers without dropping their connection. Which feature must be configured to remedy the issue?

   • Amobility MAC on the 5520 cluster
   • Bmobility MAC on the 9800 WLC
   • Cnew mobility on the 5520 cluster
   • Dnew mobility on the 9800 WLC

   Show answer

   Answer: B

   Explanation

   https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-7/High_Availability_DG.html#pgfId-44041 "When the HA pair is set up, by default, the Primary WLC's MAC address is synced as the Mobility MAC address on the Standby WLC" -> Devices in 5520 HA cluster already have the mobility mac. https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/config-guide/b_wl_16_10_cg/mobility.html "Ensure that you configure the mobility MAC address using the wireless mobility mac-address command for High-Availability to work" -> Mobility MAC needs to be set manually on new Catalyst 9800.

10. Question 160 · 1003 in bank

    

    Refer to the exhibit. Which configuration change ensures that R1 is the active gateway whenever it is in a functional state for the 172.30.110.0/24 network?

    • AR2 standby 1 priority 90 standby 1 preempt
    • BR2 standby 1 priority 100 standby 1 preempt
    • CR1 standby 1 preempt R2 standby 1 priority 90
    • DR1 standby 1 preempt R2 standby 1 priority 100

    Show answer

    Answer: C

    Explanation

    Setting R1 to preempt means take over the role when online, setting R2 to 90 means it will lose to a higher value in an election. 100 is default.
