NEW QUESTION # 169
An engineer enables the HSRP feature on a Cisco Nexus 7000 Series Switch. It must be ensured that the switch manages packets that are sent to the local vPC MAC address, remote vPC MAC address, and HSRP virtual MAC address.
Which command accomplishes this goal?
- A. peer-gateway
- B. hsrp preempt
- C. map-server
- D. peer-switch
Answer: A
Explanation:
The peer-gateway command allows each vPC peer to intercept and process packets destined to the MAC address of the other peer (remote vPC MAC) as well as the local and HSRP virtual MAC addresses.
This prevents the need for such packets to traverse the vPC peer link, reducing unnecessary traffic and avoiding packet drops caused by vPC loop avoidance mechanisms.
It effectively enables the Nexus switches in a vPC domain to route packets destined for each other's MAC addresses and for the HSRP virtual MAC, ensuring proper forwarding and load sharing in the presence of HSRP and vPC.

NEW QUESTION # 180
Which type of encoding is used on 8-Gbps links as compared to 10-Gbps links?
- A. 8-Gbps links and 10-Gbps links use 64B/66B encoding.
- B. 8-Gbps links use 64B/66B encoding, and 10-Gbps links use 8B/10B encoding.
- C. 8-Gbps links and 10-Gbps links use 8B/10B encoding.
- D. 8-Gbps links use 8B/10B encoding, and 10-Gbps links use 64B/66B encoding.
Answer: D
Explanation:
1, 2, 4, and 8 Gb Fibre Channel all use 8b/10b encoding. Meaning, 8 bits of data gets encoded into 10 bits of transmitted information - the two bits are used for data integrity. Well, if the link is
8Gb, how much do we actually get to use for data - given that 2 out of every 10 bits aren't "user" data? FC link speeds are somewhat of an anomaly, given that they're actually faster than the stated link speed would suggest. Original 1Gb FC is actually 1.0625Gb/s, and each generation has kept this standard and multiplied it. 8Gb FC would be 8 1.0625, or actual bandwidth of
8.5Gb/s. 8.5*.80 = 6.8. 6.8Gb of usable bandwidth on an 8Gb FC link.
10GE (and 10G FC, for that matter) uses 64b/66b encoding. For every 64 bits of data, only 2 bits are used for integrity checks. While theoretically this lowers the overall protection of the data, and increases the amount of data discarded in case of failure, that actual number of data units that are discarded due to failing serialization/deserialization is minuscule. For a 10Gb link using
64b/66b encoding, that leaves 96.96% of the bandwidth for user data, or 9.7Gb/s.

NEW QUESTION # 184
Refer to the exhibit. A Cisco engineer is configuring a customer scenario with 2 x MDS 9000 switches 24 x UCS B200M6 blade servers. UCS 64S4 Fabric Interconnect in end-host mode and
3 x UCS 5108 server chassis with 2408 Fabric Extenders. The engineer installs 6 x SQL Server
2019 on all blades and then notices that there are read and write latencies.
What is the best way to balance the utilization across the shared ports?
- A. Disable restrictions on oversubscription ratios
- B. Enable "Only dedicate rate mode
- C. Change the assigned speed to 8 Gbps Auto.
- D. Set 4 Gbps performance buffers
Answer: A
Explanation:
When restrictions on oversubscription ratios are disabled, the bandwidth allocation among the shared ports is proportionate to the configured speed. (If the configured speed is auto, then bandwidth is allocated assuming a speed of 4 Gbps.) For example, if you have three shared ports configured at 1, 2, and 4 Gbps, then the allocated bandwidth ratio is 1:2:4. In Cisco SAN-OS Release 3.0 and later (or when restrictions on oversubscription ratios are enabled), port bandwidths are allocated in equal proportions, regardless of port speed, so, the bandwidth allocation for the same three ports mentioned in the example would be 1:1:1.

NEW QUESTION # 185
A Cisco engineer is analyzing a customer environment where dozens of VMs are running on a physical server and UCS chassis are cascaded The setup uses two ISLs in a port channel to the SAN switch (per fabric) The oversubscription from VM to physical SAN port is often 20 (VMs/host) x 72 (9 UCS chassis cascaded = 72 hosts): 2 (ISLs from fabric interconnect to SAN switch port on the NPV core (NPIV enabled switch) This results to 20 x 72 2 per single ISL = 720 VMs per ISL
20 (VMs per host) x 8 (hosts per chassis) x 9 (chassis per port channel to SAN switch) / 2 (ISLs per port channel) = 20 x 8 x 9 / 2 = 720 VMs per SAN F-port What is the best way to resolve possible IOPS bottleneck?
- A. Deploy a content delivery network
- B. Enable Windows 1Gb server full duplex
- C. Remove data encryption on the SSD
- D. Configure 802 1Qbb priority flow control
