Question 2

In a VXLAN EVPN fabric, which protocol is used to exchange MAC and IP address reachability information among VTEPs?

Accepted Answer

BGP. In a VXLAN EVPN fabric, BGP (Border Gateway Protocol) is used as the control plane protocol to exchange MAC and IP address reachability information among VTEPs. Specifically, MP-BGP (Multiprotocol BGP) with EVPN address family (AFI L2VPN / SAFI EVPN) carries Type-2 routes (MAC/IP advertisement) to distribute host reachability across the overlay network, enabling efficient MAC learning and ARP suppression.

Answer

IS-IS

Answer

EIGRP

Answer

OSPF

Question 3

Which TWO statements about Fibre Channel zoning are correct? (Choose two.)

Accepted Answer

Zoning can be used to prevent unauthorized access to storage targets.. Fibre Channel zoning restricts which initiators can communicate with which targets, effectively preventing unauthorized access to storage LUNs. By defining zone members (via WWN or port ID), the fabric enforces these access controls at the switch level, ensuring that only devices within the same zone can exchange Fibre Channel frames.

Answer

Zoning is required to increase the distance between a host and storage.

Answer

Zoning can only be applied within a single VSAN.

Answer

Zoning is used to load balance traffic across multiple paths.

Question 4

An engineer is configuring a UCS service profile for a blade server that will boot from SAN. The storage is connected via FC SAN. Which policy must be included in the service profile to define the WWPNs for the HBAs?

Accepted Answer

SAN connectivity policy. The SAN connectivity policy in a UCS service profile defines the WWPNs and WWNNs for the Fibre Channel HBAs (vHBAs) on the blade. It specifies the vHBA interfaces, their fabric assignments (A/B), and the WWPN pool used to assign addresses. Without a SAN connectivity policy, the service profile cannot present FC HBAs to the OS, and boot-from-SAN would fail.

Answer

Network control policy

Answer

Boot policy

Answer

vNIC placement policy

Question 5

In a centralized anycast gateway VXLAN EVPN design, which is a requirement?

Accepted Answer

All VTEPs share a common anycast IP address for the default gateway.. In a centralized anycast gateway VXLAN EVPN design, all VTEPs share a common anycast IP address and MAC address for the default gateway. This allows any VTEP to serve as the first-hop router for hosts, enabling optimal east-west traffic forwarding without requiring a separate gateway device. The anycast IP is configured on each VTEP's VLAN interface, and the same IP/MAC is advertised via EVPN Type-2 routes.

Answer

Each VTEP has a unique anycast IP address.

Answer

The anycast gateway is configured on the spine switches.

Answer

The route reflector is an external BGP speaker.

Question 6

In ACI, a tenant requires that all traffic between two EPGs is denied except for specific HTTP traffic. Which policy elements must be configured?

Accepted Answer

Create a contract with a subject that includes a filter for HTTP only. ACI uses a whitelist model. To allow only HTTP, a contract with a subject and filter for HTTP is applied, and no other filters are included.

Answer

Use an external firewall for filtering

Answer

Create a taboo contract to deny all traffic and a separate contract to allow HTTP

Answer

Create a filter for HTTP and apply it directly to the EPGs

Question 7

A UCS C-series server is deployed in standalone mode and managed via CIMC. The administrator needs to mount an ISO image for OS installation. Which CIMC feature should be used to remotely attach the ISO?

Accepted Answer

Virtual media. Virtual media in CIMC allows the administrator to map a remote ISO image (from an HTTP/HTTPS, NFS, or CIFS share) as a virtual DVD/CD-ROM drive to the host, so the server can boot from it and install an OS without physical media. This is the standard CIMC feature for remote OS installation on standalone C-series servers.

Answer

KVM console

Answer

Serial over LAN

Answer

Remote firmware update

Question 8

Which Fibre Channel port type is used to connect two Cisco MDS switches together to form an inter-switch link (ISL)?

Accepted Answer

E-port. An E-port (Expansion port) is the Fibre Channel port type specifically designed to connect two switches together to form an Inter-Switch Link (ISL). When two Cisco MDS switches are connected, the ports on both ends negotiate to become E-ports, which carry fabric traffic between switches including FSPF routing updates, zone information, and data frames. This is the standard port type used for switch-to-switch connectivity in a Fibre Channel fabric.

Answer

N-port

Answer

NP-port

Answer

F-port

Question 9

Which TWO characteristics are true about Cisco VPC? (Choose two)

Accepted Answer

VPC allows dual-homing of a server to two different switches.. Cisco Virtual PortChannel (vPC) allows a server to be dual-homed to two different switches, enabling active-active load balancing and link redundancy. This is achieved by making the two switches appear as a single logical switch to the downstream device using the vPC protocol, which synchronizes state and forwarding information across the peer link.

Answer

VPC keepalive uses Layer 2 connectivity.

Answer

VPC requires a dedicated management VLAN.

Answer

VPC member ports can be on different VLANs on each peer.

Question 10

A storage array uses thin provisioning. A volume is created with a virtual size of 1 TB but only 100 GB of physical storage is allocated initially. What happens when the host writes data beyond the currently allocated physical space?

Accepted Answer

The array automatically extends the volume by allocating more physical blocks from the pool.. Thin provisioning decouples the volume's presented (virtual) size from its physically consumed capacity. When the host writes beyond the currently allocated blocks, the array's allocation engine automatically carves additional blocks from the shared storage pool and maps them to the volume, transparently to the host. The write succeeds as long as the pool has free space.

Answer

The write fails immediately.

Answer

The host must reconfigure the volume size.

Answer

The volume is expanded to 1 TB physical.

Question 11

A storage engineer is planning an FCoE deployment in a data center. The network must support lossless Ethernet for Fibre Channel traffic. Which three Data Center Bridging (DCB) features are required? (Choose three.)

Accepted Answer

Priority Flow Control (PFC). Priority Flow Control (PFC, option A) is required because it provides per-priority, class-based pause frames (IEEE 802.1Qbb) that prevent frame drops on the lossless CoS used for FCoE traffic, which native Fibre Channel cannot tolerate. Enhanced Transmission Selection (ETS, option C) is required because it guarantees bandwidth allocation per traffic class (IEEE 802.1Qaz) so storage, LAN, and IPC classes each receive their configured share while unused bandwidth can be borrowed. Data Center Bridging Exchange (DCBX, option E) is required because it uses LLDP TLVs to advertise and negotiate PFC, ETS, and other DCB parameters between the server CNA/NIC and the switch, ensuring consistent configuration end to end. LACP (option B) is a link-aggregation protocol for bundling links and is not a DCB lossless feature, and STP (option D) is a loop-prevention protocol that is actually undesirable in a lossless FCoE fabric, where technologies like TRILL or shortest-path forwarding are preferred.

Answer

Link Aggregation Control Protocol (LACP)

Answer

Spanning Tree Protocol (STP)

Question 12

A data center administrator is implementing FCoE on a Cisco UCS fabric. The converged network adapters (CNAs) must communicate with the Fibre Channel storage array via the FCoE forwarder. Which FCoE port type is used on the CNA to connect to the FCoE forwarder?

Accepted Answer

VN-port. A VN-port (VN_Port) is the virtual N-port emulated by a converged network adapter in an FCoE environment. It performs FLOGI with the FCoE forwarder (FCF) and behaves exactly like a physical FC N-port from the fabric's perspective, which is why it is the correct port type on the CNA side.

Answer

VE-port

Answer

VF-port

Answer

E-port

Question 13

An organization uses synchronous replication between two storage arrays for disaster recovery. Which three characteristics apply to synchronous replication? (Choose three.)

Accepted Answer

Write acknowledgment is sent only after data is written to both arrays.. Option B is correct because in synchronous replication the host write is not acknowledged until the data has been committed to both the source and the target array, guaranteeing the remote copy is identical at acknowledgment time. Option C is correct because the write must traverse the link and be committed on the remote array before the I/O completes, so round-trip latency is added to every write, making it slower than asynchronous replication. Option E is correct because, since every acknowledged write exists on both arrays, no committed data is lost on failover, yielding a zero RPO. Option A is wrong because synchronous replication typically needs more bandwidth and lower latency than asynchronous, since each write must be transmitted and confirmed in real time. Option D is wrong because high-latency, long-distance links are precisely where synchronous replication performs poorly; such links are better suited to asynchronous replication.

Answer

It requires less bandwidth than asynchronous replication.

Answer

It is suitable for long-distance links with high latency.

Question 14

Which of the following is a requirement for VPC peer keepalive to function correctly?

Accepted Answer

Must be a Layer 3 interface with unique VRF. VPC peer keepalive requires a Layer 3 interface with a unique VRF to ensure that keepalive messages are sent over a dedicated, isolated path that is independent of the peer-link. This prevents the keepalive from being disrupted by issues on the peer-link and allows the VPC peers to detect failures even when the peer-link is down. The keepalive uses UDP port 3200 and must be routed through a separate VRF to avoid conflicts with the management or default routing tables.

Answer

Must use the same IP subnet as peer-link

Answer

Must be a direct Layer 2 connection

Answer

Must be in the same VLAN as peer-link

Question 15

A network engineer wants to automate the configuration of VLANs on a Nexus 9000 switch using REST-based APIs. Which approach should be used to send NX-OS commands via HTTP/HTTPS in JSON format?

Accepted Answer

NX-API REST. NX-API REST supports XML or JSON over HTTP/HTTPS and allows configuration via RESTful operations. NX-API CLI sends CLI commands over HTTP, not REST. Guest Shell runs bash scripts. NETCONF uses XML over SSH.

Answer

Guest Shell

Answer

NETCONF

Answer

NX-API CLI
